The average production and consumption of PVC board is 1.4 million tons, which is being produced and applied worldwide with a growth rate of 4%. In recent years, the growth of PVC plastics in Southeast Asia has been particularly significant, thanks to the urgent need for infrastructure construction in Southeast Asian countries. Among the materials that can produce three-dimensional surface films, PVC plastic board is the most suitable material. Specific gravity: 1.38 g / cm3, molding shrinkage: 0.6-1.5%, molding temperature: 160-190 ° C.

Characteristics: excellent mechanical and electrical properties, strong acid and alkali resistance, good chemical stability, but low softening point. Suitable for making thin plates, wire and cable insulation layers, seals, etc.

成型 The plastic plate forming characteristics:

1. Amorphous material, small moisture absorption, poor fluidity. In order to improve fluidity and prevent air bubbles, the plastic can be dried in advance. The mold pouring system should be thick and short, and the gate section should be large without dead corners.

The mold must be cooled and the surface is chrome plated.

2. Due to its corrosive and fluid characteristics, it is best to use special equipment and molds. All products must be added with different types and quantities of additives as required.

3. It is easy to decompose. It will decompose more easily when it comes into contact with steel at 200 ° C. Corrosion will escape during decomposition. Irritating gas. The molding temperature range is small.

4. When using the nozzle of the screw injection machine, the hole diameter should be large to prevent dead angle stagnation. No inserts, if any, should be preheated.

PVC board can be seen everywhere in people's daily life. PVC can not only express the colors of nature, but also the colors of people's fantasy. In Germany, 40% of furniture is made of PVC, such as desks, bookshelves, sofas, kitchen cabinets, etc. It is a synthetic material that is loved, popular and widely used in the world today.
