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.

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%.

　　accounts for 6%-10% of the plastics used in the whole vehicle. PVC is mainly used for door trim, hoses, sealing strips, front and rear door trims, etc. in automobiles. For front and rear door trims, most cars generally use metal core materials and PVC profiles, that is, hollow profiles are extruded from PVC, and then metal core materials are inlaid in the middle to make decorative strips, and then bonded to the front and rear door outer panels of the car. In recent years, in order to further improve the application performance of PVC and expand its application range, PVC alloys have been studied at home and abroad.

　　The above is the application of PVC panels in automobiles. PVC panels are more and more widely used in our lives with other characteristics.

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.

　　Specifications: Implement GB/T13663-2000 "Polyethylene (PE) Pipes for Water Supply"; the drinking water pipe cleaning function conforms to the GB/T17219 rules; it is produced with PE100 grade materials and is generally used for pressure water transportation.

　　Features of HDPE pipe (PE pipe)PVC Foam Profile

　　1. Outstanding cleaning function: no heavy metal salt stabilizer is added during PE pipe processing, the raw materials are non-toxic, no scaling layer, and no bacteria multiply, and the secondary pollution of urban drinking water is well treated.

　　2. Outstanding corrosion resistance: Except for a few strong oxidants, it can withstand the erosion of a variety of chemical media; no electrochemical corrosion.

　　3. Long service life: PE pipes can be used safely for more than 50 years under rated temperature and pressure.

　　4. Good impact resistance: PE pipe has good resistance and high impact resistance, and heavy objects directly pass through the pipeline, which will not cause the pipeline to break.

　　5. Reliable connection function: The strength of the PE pipe's hot melt or electric melt interface is higher than that of the pipe body, and the joint will not be disconnected due to soil movement or live load.

　　6. Outstanding construction function: the pipeline is light in weight, the welding process is simple, the construction is convenient, and the construction cost is low.

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.
