The characteristics of HDPE pipe and PE pipe

 　The full name of PE is Polyethylene, which is the simplest polymer organic compound. It is the most widely used polymer material in the world today. It is polymerized by ethylene. According to the density, it is divided into high density polyethylene, medium density polyethylene and low density polyethylene. Low-density polyethylene is relatively soft, and it is mostly used for high-pressure polymerization; high-density polyethylene has the characteristics of rigidity, hardness and mechanical strength, and it is mostly used for low-pressure polymerization. High-density polyethylene can be used as containers, pipes, and high-frequency electrical insulating materials for radar and television.

How to choose a safe and reliable "water supply pipe"?

 The water supply pipe is responsible for transmitting our daily water, so the material of the water pipe directly affects the quality of water and our health. There are countless varieties of water supply pipes on the market. How to plan and select data for construction unit planners is a very serious mission, which is related to people's livelihood and project cost. This requires us to understand several types of pipelines on the market. Let's take a look at the main water supply pipe:

　　Galvanized iron pipe

　　The most widespread product in China is classified as a selected product abroad. There is only one reason. Galvanized iron pipes will rust, affect water quality, form water heavy metal overruns, and cause serious health problems. Although they are cheap, their health cannot be guaranteed.

　　pvc pipe

　　PVC (polyvinyl chloride) plastic pipe is a modern composition material pipe. However, in recent years, the scientific and technological circles have discovered that the chemical additive phthalate, which can make PVC softer, has a great impact on the kidneys, liver, and testis in the human body. It can cause cancer and kidney damage, damage the human body's functional reconstruction system, and affect development. In the process of other re-production, pipelines are required to have a beautiful appearance and stable delivery speed. Stabilizers are often required. Stabilizers contain a large amount of heavy metals. This is a major damage. Heavy metals can pollute the soil and pollute water. Generally speaking, Because its strength is far from suitable for the pressure requirements of water pipes, it is rarely used in water pipes. In most cases, PVC pipes are suitable for wire pipes and sewage pipes.

　　PPR tube

　　The PP-R water supply pipe is now the most popular product. The most popular in the world is the American polygon pipe, which is called Poly Pipe in my country. Its water supply pipe series include: PPR antibacterial pipe, PPR steady-state aluminum clad, and PPR copper pipe , PPR boutique pipes, etc. are all classified as first-line products in shopping malls. They are safe, stable, moderately priced, relatively cost-effective, and have a 50-year warranty.

　　Copper tube

　　The cost is moderately expensive and can be made by non-ordinary collectives. Only the local tyrants have the strength to enjoy it. Many foreign high-end sanitary wares often show the shadow of copper pipes. Although good, the price is high. The PPR copper pipes produced by Poly Pipeline now combine the advantages of copper pipes and PP-R pipes. The use of red copper with a purity of 99.99% or more is used for sterilization, antibacterial, and good cleaning functions. The thermal conductivity is lower than that of copper pipes, and it has excellent heat preservation function, which is suitable for high-end residential buildings.

　　stainless steel pipe

　　Very good product, unfortunately the material is too hard and the price is too high, which leads to inconvenient processing, easy damage, and high probability of spoilage. Therefore, stainless steel pipes are rarely seen in the process of using and processing.

　　Aluminum-plastic composite pipe

　　Aluminum-plastic composite pipe is one of the most popular pipes on the market now. Because of its light weight, ease of use and convenient construction, its flexibility is more suitable for use in home furnishings. The main defect is that when used as a hot water pipe, due to long-term thermal expansion and contraction, the pipe wall will be misaligned and cause leakage.

　　Stainless steel composite pipe

　　Stainless steel composite pipes are similar in structure to aluminum-plastic composite pipes, and to a certain extent, their functions are relatively close. Similarly, due to the strength of steel, the construction process is still a problem.

　　HDPE water supply pipe

　　HDPE water supply pipes are now the most important and mainstream pipelines on the market. High-quality PE water supply pipes are not only safe and clean, but also antibacterial, non-scaling, simple in construction, and will not be damaged after 50 years of continuous use. The failure rate is extremely low. The Xintong water supply pipeline adopts advanced equipment, the appearance of the produced pipeline is lubricated, the wall thickness is accurate, the out-of-roundness is low, and the pressure-bearing capacity is strong.

PVC Modification Method

 　　PVC resin is a polar non-crystalline polymer, density: 1.38 g/cm3, glass transition temperature: 87°C, so it has poor thermal stability and is difficult to process. It cannot be used directly, it must be modified and compounded, and related additives and fillers can be added before it can be used. However, due to the different types and fractions of related additives and fillers added, this determines that the properties and requirements of the prepared PVC materials are different.

PVC Extruding has focused on plastic extrusion and injection molding for several years in China. We started as a small operation, but now have become one of the leading suppliers in plastic extrusion industry in China.

Today, PVC Extruding has been one of the top producers of PVC Foam extrusions,PVC profiles,ABS profiles,PC extrusions and PP+FIBERGLASS extrusions etc.

　　We usually call it PVC formula, strictly speaking, it is PVC modified formula, and PVC can only be used after modification. This category is often classified as polymer modified materials. The modification of polymer materials mainly focuses on research on the high performance of general-purpose plastics, the conversion of single-component materials to multi-component composite materials (alloys, blends, and composites), functionalization of materials, and optimization of performance and price.

　　Modification methods are mainly chemical modification, filling modification, reinforcement modification, blending modification and nano-composite modification. The basic principle of modification is to give materials functions or improve certain properties through additives. Therefore, the level of PVC formulation technology determines the level of technology and production capacity of a factory.

Advantages of PVC foam sheet

 　　PVC foam board

　　The new environmentally friendly PVC foamed board can play a certain role in advertising exhibitions. It can produce various advertising exhibition boards, booths, signs and public signs, etc., with simple production and convenient installation.

　　PVC foam board has many advantages. For example, "Home Decoration PVC Board" is paying more attention to safety and environmental performance, comfortable performance and special environmental performance, and "Commercial PVC Board" is more focused on durability, economic performance, cleaning and maintenance. PVC foamed sheet is generally not polluted in the production and development process, and it is relatively green and environmentally friendly.

　　3. PVC film

　　The consumption of PVC in the field of PVC film ranks third, accounting for about 10%. After PVC is mixed with additives and plasticized, a three-roll or four-roll calender is used to make a transparent or colored film with a specified thickness. The film is processed in this way to become a calendered film. It can also be cut and heat-sealed to process packaging bags, raincoats, tablecloths, curtains, inflatable toys, etc. The wide transparent film can be used for greenhouses, plastic greenhouses and mulch films. The biaxially stretched film has the characteristics of heat shrinkage and can be used for shrink packaging.

　　4. PVC hard materials and plates

　　Stabilizers, lubricants and fillers are added to PVC. After mixing, the extruder can be used to extrude hard pipes, special-shaped pipes and corrugated pipes of various calibers, which can be used as sewer pipes, drinking water pipes, wire casings or stair railings. . The calendered sheets are overlapped and hot pressed to make hard plates of various thicknesses. The plate can be cut into the required shape, and then welded with hot air with PVC welding rod to form various chemical resistant storage tanks, air ducts and containers.

　　5. PVC general soft product

　　The extruder can be used to squeeze into hoses, cables, wires, etc.; the injection molding machine can be used with various molds to make plastic sandals, shoe soles, slippers, toys, auto parts, etc.

　　6. PVC packaging materials

　　Polyvinyl chloride products are mainly used for packaging in various containers, films and rigid sheets. PVC containers mainly produce PTP packaging for mineral water, beverages, cosmetics packaging bottles, medicines, and packaging for refined oil. PVC film can be used to co-extrude with other polymers to produce low-cost laminates and transparent products with good barrier properties. Polyvinyl chloride film can also be used for stretch or heat shrink packaging for packaging mattresses, cloth, toys and industrial goods.

PVC profile blister process and application range

 　　PVC blister is a kind of plastic profile processing technology. The main principle is to heat the flat PVC profile sheet, then after it becomes soft, it is adsorbed on the surface of the mold by vacuum, after cooling, it is formed, and then it can be widely used in PVC sheet Packaging, lighting, advertising, decoration and other related industries of profile products.

　　Blister packaging products mainly include: blister, tray, blister box. Also known as: vacuum cover, blister, etc., blister packaging equipment mainly includes: blister forming machine, punching machine, sealing machine, high frequency machine. For folding machines, packaging products formed by encapsulation can also be divided into: plug-ins, blister card double blister, half blister, half-fold blister, three-fold blister, etc.PVC Extrusions

　　In the blister process, the transparent PVC profile hard sheet is made into a specific convex transparent plastic, which is covered on the surface of the product to protect and beautify the product. The ordinary plastic is hardened and a layer is glued on the surface. The solute material, so that the surface of the tray has a solute feel, which is used to improve the grade of the packaged product. The plastic tray of the modified material with a special process is mainly used for the electrostatic tray of electronic and IT products.

　　The mold used for blister production, the lowest cost is the plaster mold, the second is the electroplated copper mold, and the most expensive is the aluminum mold. The mold is drilled with small holes for vacuum adsorption and heating of the hard sheet to form a blister PVC plastic profile. product.

　　In the blister we often talk about, a blister forming machine is used to adsorb the thermally softened plastic hard sheet on the surface of the mold, and after cooling, a concave-convex shape plastic is formed.

　　Blister cutting: The plastic product after blister packaging is formed, and the large sheet is divided into individual products by a knife through a punch.

　　Folding: One of the PVC blister packaging products is called plug-in packaging.It is necessary to fold the three sides of the blister to the back with a folding machine, so that in the next packaging process, the paper card is inserted into the folding to form a plug-in package.Plastic Foam Extrusions

　　Heat sealing: It is a kind of blister packaging process. The paper card coated with blister oil on the surface and the blister are also combined with a sealing machine to form a blister card package.

　　High-frequency sealing: It is a process of blister packaging, mainly using a high-frequency machine to generate ultrasonic waves, and then bonding the blister and the blister together to form a double blister packaging. The difference from high-frequency sealing is that the ultrasonic It can not only seal PVC, PET, PETG and other materials, but also PET materials, and there is no electromagnetic damage to the packaged products. It is especially suitable for the packaging of electronic products: but the disadvantage is that the ultrasonic edge sealing can only be separated by dots. And in general, only one side can be sealed at a time.

How To Store PVC Foam Board Correctly?

 

　　Placement method of PVC foam board

　　1. Do not place the PVC foam board in a place directly exposed to the sun or on a car, because the PVC foam board will be severely deformed at high temperatures, so you must avoid placing it in a high temperature environment.

　　2. All PVC foam boards should not be stored upright. They must be placed flat on a flat ground. If the PVC foam boards are placed upright, they will bend and deform after a period of time.

　　Three. During the transportation of PVC foam board, please use wooden drag or paper wrapper to prevent it from deforming during transportation

The future development prospects of PVC foam board

 　　The PVC foamed sheet is produced on the CM80 conical twin-screw extrusion line introduced from Millekron in Cincinnati, Austria. The quality is very good, and the colors are gray and white. Polyvinyl chloride colored boards can be produced according to customer requirements. The colors are bright and beautiful. PVC hard board has good chemical stability, corrosion resistance, high hardness, high strength, anti-ultraviolet (anti-aging), fire and flame retardant (self-extinguishing), reliable insulation performance, smooth appearance, no water absorption, no deformation, and easy processing And other unique features. It is a good thermoforming material and can replace local stainless steel and other synthetic materials such as corrosion

　　First of all, the country is in the midst of an upsurge in environmental protection. The "14th Five-Year Plan" of Guangdong Province should promote green and low-carbon development, formulate and implement carbon emissions peaking actions, and promote carbon emissions to peak first. The green and environmental advantages of PVC foam board can guarantee its product status.

　　There is no doubt about the environmental performance of PVC foam board in the current sheet market. Its production process does not need to cut wood, nor does it need to burn coal to mine metal ore, which coincides with the national environmental protection boom. And its performance is not worse than any traditional board, which makes it more competitive in future development.

　　Secondly, it does not need to increase the cost to replace the traditional board, and it can even reduce the economic cost.

　　PVC foam board does not need to add additional cost to replace traditional board, because its own performance can be compared with traditional board, even in certain specific aspects such as acid and alkali resistance, corrosion resistance, etc. It is better than traditional boards, and even the cost reduction brought about by this performance will be popular in the market. It is applied in more and more fields, which also gives it a broad space for development.

　　In recent years, the advantageous PVC foam board has gradually attracted the attention of the market. More and more fields are willing to buy and use boards with good performance from manufacturers, which also makes the share of PVC foam board in the board market rise all the way, and the future development space is very broad.

　　In short, whether it is development opportunities based on national policies, or the advantages of PVC foam board itself and the attention of a wider range of fields, its future development is bound to be unlimited. With the investment in research and development costs, more types and higher quality PVC foam boards will enter the market, which will benefit more areas.

White PE pipe of LDPE pipe

 　What is the white PE pipe? When the customer re-constructs or purchases, they will encounter the design institute or the industry mainly designated white PE pipes. So what is the white PE pipe? Here we give an introduction to several varieties of white PE pipes.

　　One: LDPE tube

　　LDPE pipes are actually low-density PE pipes. PE itself is divided into high-density polyethylene (HDPE) and low-density polyethylene (LDPE). The color of LDPE pipes is snow-white, usually coiled pipes. However, the amount of straight pipes is gradually increasing. , LDPE pipe is mainly used for threading. It is characterized by being transparent and relatively hard. The defect is that it cannot be pulled up. It is not suitable for trenchless pipe jacking.

　　Two: HDPE pipe

　　HDPE pipes are high-density polyethylene pipes. The HDPE material itself is white. The main reason why the PE pipes we see on the market are black is that the black master is added. From the perspective of the use of pipes, the addition of After the black mother, the pipe is not clear, so that the possibility of breeding harmful bacteria is reduced. The pipe made of pure new material HDPE material is white without adding black masterbatch. This kind of pipe has the advantages of two layers of stretchability and ring stiffness, and the sanitary index is also passed, but the cost is high, so the general market will not choose it. , Unless there are special requirements, of course, it is even more unlikely to be used for power threading pipes.

　　Three: Hybrid PE pipe

　　Due to the needs of customers or owners, it is necessary that the color of the PE pipe needs to be white, so it is possible to mix LDPE and HDPE materials in the production, and perhaps also use high-quality HDPE recycled materials. Many customers here think that recycled materials are not good materials. In fact, this is a very wrong concept. Some functional indicators of the application of recycled materials in foreign countries are better than brand-new materials. The white PE pipe made with the mixed formula has good functions, and the cost is relatively low compared with pure HDPE material. It is suitable for market application and is the most mainstream non-excavation power PE pipe.

The mystery of whitening PVC foam board

 　　PVC foam board is a fireproof material for decoration. Because of its moisture-proof, weather-resistant, impact-resistant, thermal insulation, acid and alkali corrosion resistance, and flame resistance, it is widely used in indoor light partition materials, audio-visual space sound insulation materials, Fireproof materials, packaging materials for refrigeration and air-conditioning projects, roof insulation materials and furniture interior materials, etc. The PVC foam board uses polyvinyl chloride as the main raw material, and is extruded with special equipment by adding foaming agent, flame retardant, and anti-aging agent. Among them, the special fluorescent brightener for foam board is also an indispensable chemical additive in PVC foaming.

　　Since PVC is a plastic raw material that can be recycled many times, in order to reduce production costs and respond to the national resource and environmental protection call, many manufacturers will choose to use recycled and pelletized PVC materials to make new products. Although the cost has been reduced a lot, because the materials of polyvinyl chloride products are more complex, in addition to resin, there are a certain amount of auxiliary materials such as plasticizers, stabilizers, lubricants, and pigments. These additives are exposed to light and heat in the process of use, which will produce varying degrees of volatilization and loss, and PVC will also degrade to a certain extent. Therefore, when reusing recycled materials to produce foamed boards, an appropriate amount of stabilizers, lubricants and other related ingredients are required to ensure that the PVC foamed boards processed from recycled materials have good physical and mechanical properties.

　　Because the color of the recycled material turns yellow, the appearance looks particularly unattractive. In order to make the recycled material foam board as bright as new material, Zheyuan Chemical recommends that the foam board manufacturer add a special fluorescent brightener for the foam board to increase White. Fluorescent brighteners are a class of compounds that can absorb ultraviolet light and emit blue or blue-violet visible light. Many industrial products, such as textiles, paper, plastics, etc., often have a visually undesirable yellow hue. Fluorescent brighteners use the principle that blue and yellow are complementary colors to whiten the product. Adding the whitening agent for PVC foaming can remove the yellow color and make the foamed PVC look white and bright. The adding method of the whitening agent for PVC foaming is also very simple. It only needs to be added when the PVC is mixed and mixed thoroughly.

How much is a PVC foam board?

 　PVC expansion sheet is also called Chevron board and Andy board. Take polyvinyl chloride as the main raw material, add foaming agent, flame retardant, anti-aging agent, and use special equipment to extrude. It is widely used in construction, vehicle and ship manufacturing, furniture, decoration, decoration, advertising production, exhibition signs, city appearance and environmental protection, tourism and other industries. The advertising characters are made by an engraving machine or by hand, and the thickness is generally 0.3-2 cm. There are two common production methods: one is crust foaming, with a hard skin on the surface, smooth and flat; the other is free foaming, with no crust on the surface, and the surface is finely uneven (pitted surface). Common colors are white and black.

　　Chevron board is comparable to wood, and it can be sawn, planed, nailed, glued, and has special functions such as no deformation, no cracking, and no need to paint (with a variety of colors); while low-foaming boards can be welded, It is printed with ink and can also be machined by sawing, drilling, milling and other methods.

Precautions for the paint design of PVC foam board

 　PVC foam board has a smooth surface, high hardness, and is not easy to be scratched. It is often used in various industrial buildings and household productions. So what should be paid attention to when designing the paint surface of PVC foam board?

　　1. You can use the engraving machine to shape according to the design drawing, and then choose the surface to be pasted with Meinai board or paint; but the hollow foam board needs to pay attention, if the surface is uneven, you can only use vacuum overmolding. , The material should be 2mm thick PVC board.

　　2. Bending molding is only suitable for solid foamed boards, hollow foamed boards are not applicable; the processing method is to use upper and lower molds, cover the surface of the wooden mold with aluminum plates and heat the solid foamed boards to a plasticizing temperature of 70~90℃ In the meantime, the surface of the foamed board is extruded directly by the upper and lower molds without any change.

　　3. Self-adhesive PVC can provide wood grains with different patterns on the surface according to requirements during extrusion manufacturing, which can save unnecessary processing procedures.

　　4. The surface of PVC foam board can be painted, and the general category can be divided into general baking varnish, piano baking varnish, ceramic baking varnish according to different processing methods; anti-UV ingredients will be added during piano baking varnish processing to avoid surface color changes; In terms of surface hardness, ceramic baking varnish has the advantage of anti-scratch.

PVC board molding characteristics

 　Among the materials that can produce three-dimensional surface film, PVC board is a more suitable material. Specific gravity: 1.38 g/cm3, molding shrinkage rate: 0.6-1.5%, molding temperature: 160-190°C.

　　PVC board molding characteristics:

　　1. Easily decompose, and steel at a temperature of 200 degrees. Copper contact is easier to decompose, and corrosion will escape when it is decomposed. Irritating gas. The molding temperature range is small.

　　2. When using screw injection machine nozzles, the aperture should be large to prevent dead ends from stagnating. Fortunately without inserts, if there are inserts, they should be preheated.

　　3. Amorphous material, low moisture absorption, poor fluidity. In order to improve fluidity and prevent bubbles from occurring, the plastic can be pre-dried. The mold gating system should be short and thick, and the gate section should be large, and there should be no dead corners. The mold must be cooled and the surface is chrome plated.

　　4. Due to its corrosive and fluid characteristics, special equipment and molds can be used. All products must be added with different types and quantities of additives according to needs.

　　The full name of PVC board is Polyvinylchlorid. The main component is polyvinyl chloride. It has bright color, corrosion resistance and durability. Due to the addition of plasticizers, anti-aging agents and other toxic auxiliary materials in the manufacturing process to enhance its heat resistance and toughness , Ductility, etc., so its products generally do not store food and medicine.

　　PVC board is a kind of synthetic material that is well-loved, popular and widely used in the world today. Its global usage ranks second among various synthetic materials. According to statistics, in 1995 alone, the production of PVC sheets in Europe was about 5 million tons, while its consumption was 5.3 million tons.
