The average production and consumption of PVC transparent board is 1.4 million tons, and it 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.
Features: mechanical properties, excellent 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.
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 casting system should be thick and short, and the gate cross-section should be large. There must be no 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. Extremely easy to decompose, contact with steel at 200 ° C. Copper will be more easily decomposed, and corrosion will escape during decomposition. Irritating gas. Small molding temperature range.
4.When using the nozzle of the screw injection machine, the hole diameter should be large to prevent dead corners. No inserts, if any, should be preheated.
PVC board is 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.
