Pvc Plastic Shelf Dividers

 　　The yellowing of PVC profiles is mostly due to the presence of paste at the die. The reason is that the die runner is unreasonable or the local polishing in the runner is not good, and there is a stagnant area. The yellow line of PVC profile is mostly due to the presence of paste in the barrel. The main reason is that there is a dead corner between the sieve plates (or transition sleeves) and the material flow is not smooth. The yellow line is a vertical straight line on the PVC profile, the stagnant material is at the exit of the die; if the yellow line is not straight, it is mainly in the transition sleeve. Yellow lines appear when the formula and raw materials are unchanged, the reason should be found mainly from the mechanical structure, and the starting point of decomposition should be found and eliminated. If the reason cannot be found from the mechanical structure, it should be considered that there is a problem with the formula or process. The measures to avoid degradation include the following aspects:

• PVC Extrusions
  • PVC Foam Profile
  • PVC Profile
  • PVC Pipes
  • PVC Tube
  • PVC Divider
• PC Extrusions
• ABS HDPE PP Extrusions
• Injection Molding

　　Strictly control the technical indicators of raw materials and use qualified raw materials;

　　Formulate reasonable molding process conditions, under which PVC materials are not easy to degrade;

　　The molding equipment and mold should be well-structured, and the dead corners or gaps that may exist on the contact surface between the equipment and the material should be eliminated; the runner should be streamlined and the length is appropriate;

　　The heating device should be improved, the sensitivity of the temperature display device and the efficiency of the cooling system should be improved.

The heating device should be improved, the sensitivity of the temperature display device and the efficiency of the cooling system should be improved.

 　Polyvinyl chloride PVC is an economical and general-purpose thermoplastic polymer, which is widely used in the construction and construction industries to produce door and window profiles, pipes, wire and cable insulation, and medical equipment. It is the world's three largest thermoplastic materials together with polyethylene and polypropylene. Due to the poor molding performance of the processed PVC profile, such as high melt viscosity, poor fluidity, poor thermal stability, easy thermal decomposition, poor aging resistance, easy to become brittle, hard, crack, and poor toughness, The cold resistance is not good, so PVC modification is generally required to make up for the above shortcomings.

　　Physical modification: Physical modification is to improve its performance by adding various additives or filling, blending, and strengthening.

　　1. For example, adding ACR to improve the molding and processing performance of PVC materials; adding internal and external lubricants or polyethylene wax to improve the viscosity and fluidity of the materials; adding thermal stabilizers to improve the thermal stability of the materials during molding and reduce their Decomposition temperature; adding antioxidants and anti-ultraviolet agents to improve the anti-aging life of PVC profile products; adding plasticizers to improve the plasticizing performance of materials and increase the softness of products. Filling modification is to improve certain properties by adding inorganic or organic fillers.

　　2. Such as adding wood powder filler to reduce the specific gravity of PVC products, close to wood; adding metal powder, such as copper powder, aluminum powder to improve the conductivity of the product; adding iron oxide magnetic powder to improve the magnetic properties of the product; adding calcium carbide to improve the product Hardness, while reducing material costs; adding red mud to improve the heat resistance and light aging resistance of the product, while reducing material costs.

　　3. For example, other polymers that can be blended and modified with PVC include acrylonitrile-butadiene-styrene copolymer (ABS), methyl methacrylate-butadiene-styrene copolymer (MBS), poly Acrylate, chlorinated polyethylene (CPE), ethylene-vinyl acetate copolymer (EVA), nitrile rubber, ethylene propylene rubber, chlorinated polyvinyl chloride (CPVC), dioctyl maleate, etc.

　　4. In addition, PVC modification methods such as reinforced modification, crosslinking modification, foaming modification, and radiation modification can also be used to improve the performance of PVC. For example, use mica powder with a large aspect ratio for reinforcement; use dicumyl peroxide (DCP) for cross-linking modification to increase strength; use azodicarbonamide foaming agent to reduce the specific gravity of PVC products, and use cobalt radiation for Irradiate, increase intensity, etc.

The mixing technology and feeding sequence of PVC low-foaming raw materials

 　The preparation of pvc low-foaming dry blend is carried out on a standard heating and cooling mixing unit (this unit is a combination of a high-speed mixer and a cooling mixing unit). The mixing principle of the high-speed mixer is that the materials are rapidly scattered along the container wall under the impetus of the high-speed rotating stirring blade, and fall from the center of the container to form a vortex motion to achieve the effect of rapid mixing and uniformity. During high-speed

PVC Extrusions stirring, when the materials are mixed, friction between the materials will be generated, that is, frictional heat will be generated at the same time. There will also be friction

http://upvcextrusion.com/ between the materials and the stirring blade and the container wall, and frictional heat will also be generated, as well as the heating source outside the container. Under the joint action, various

Injection Molding

PC Extrusions additives can quickly infiltrate into the PVC resin and form a semi-gelled dry mixture. The principle of the cooling mixer is to pass cooling water through the outer jacket of the container, and under the low-speed stirring of the paddle, the dry mixture of about 110-120℃ is rapidly cooled to below 45℃ to prevent the hot material from agglomerating, decomposing and foaming. , The mixed dry blend discharged from the mixer should be sieved to remove agglomerates and molten particles for the next step of extruding and granulating, or directly extruding low-foaming products.

Six common senses of PVC foam board processing

 The processing characteristics of pvc foam board are roughly the same as that of wood processing. It is only necessary to avoid scorching caused by excessively high working temperature. In addition, the chips generated after processing can be collected, recycled, and remanufactured to reduce costs. There is one thing to pay attention to when cutting the hollow foam board. Because the hollow space is 23mm, it is easy to assemble. If you don’t pay attention to cutting, most of them are overlapped and cut at one time, resulting in different spacing; you can use the tool It is positioned by the way of bolts, which is convenient for processing. Now we understand a little bit of common sense about the surface processing of PVC foam board.

1. The engraving machine can be used to shape according to the design drawing, and the surface is to be pasted with Minai board or baking varnish; but the hollow foam board should be noted that if the surface is uneven, only the vacuum overmolding method can be used and the material is 2 mm pvc board.

2. 
   

　　2. Bending molding is only suitable for solid foamed board, hollow foamed board is 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 board 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 the 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.

　　5. Then there is the common processing method. The surface is pasted with crystal plate (usually single-sided colored acrylic plate), Minai plate and Minai paper. In the part of the edge banding, the general processing is mostly automatic edge banding machine. The automatic edge banding machine is divided into two types: roller type and crawler type. However, if hollow foaming is used, it is recommended to use a color similar to that of the surface coating material to avoid obvious color difference when the paper is pasted. .

　　6. Drilling can be beneficial to the crawler edge banding machine, which is less likely to cause unevenness on the surface after edge banding. The pressure adjustment is also very important; the color of the foam board is also directly processed by the NC machine. The material itself can reduce the density and increase the air content of the foam board according to the needs of the application, to achieve the effect of heat insulation and sound insulation and cost reduction. For example, the density of 15mm foam board reduces its own weight and the same volume of 10mm foam board. The weight is the same. At present, some manufacturers have used the foaming board to use vacuum forming for table top molding or large machine cover, but there is a disadvantage when applied to the table top molding, which is that the surface is not well resistant to mold and is easy to wear.

PVC board used in cars

 　The pvc board is a honeycomb-shaped cross-section made of PVC as a raw material. With the forward development of the automobile industry, more and more plastics are applied to automobiles. With people's serial requirements for automobile safety, environmental protection, and energy saving, we urgently need comprehensive performance plastic materials and automobile plastic parts. It is also used more and more widely, and it has been developed from interior and exterior decorative parts to car body covering parts and structural parts. For example, the front face, bumper, engine hood, trunk lid, roof, fender, door inner guard and certain body frame components.

Why PVC foam board is suitable for home decoration

　　The main component of pvc board is polyvinyl chloride, and other components are added to enhance its heat resistance, toughness, ductility, etc. It 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 in Europe was about 5 million tons, while its consumption was 5.3 million tons. In Germany, the production and consumption of PVC is an average of 1.4 million tons. PVC is being produced and applied worldwide at a growth rate of 4%.

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.

Appearance characteristics of PVC rigid board

 　PVC hard board appearance: smooth, flat surface, no cracks, no bubbles. The color is generally gray, white, and can be used to produce blue, black, computer color and other purposes; PVC hard boards are processed into various acid and alkali corrosion resistant chemical equipment through secondary processing. It is widely used in chemical, electroplating, smelting, and water treatment industries. Nowadays, the construction and decoration material industries use PVC boards as templates, which are in great demand. But it is not suitable for food container.

The main use and industrial chain of PVC

 　　1. PVC profile

　　Profiles and profiles are the largest area of PVC consumption in my country, accounting for about 25% of total PVC consumption. They are mainly used to make doors and windows and energy-saving materials. At present, their applications are still growing nationwide.

High Quality Custom HDPE Extrusion Hollow Profile

　　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.
