PVC board to PVC as raw materials, can waterproof, moisture-proof, decay. Contains flame-retardant raw materials, so the use of safety. PVC plastic plate mostly plain-based, there are imitation patterns, imitation marble pattern. Its cross-section of the honeycomb-shaped mesh structure, both sides of the processing of the mouth and the tongue and groove processing, which is the details of the selection, I asked the mouth and the tenon completely flat, smooth bite each other, no local ups and downs and height difference. PVC plastic sheet per square meter 12 to 20 yuan range, can be described as inexpensive. PVC plastic plate features: mechanical properties, excellent electrical properties, strong acid and alkali resistance, chemical stability, but the softening point is low. Suitable for the production of sheet metal, wire and cable insulation, seals, etc. Its global use in the Of synthetic materials in the second highest. PVC is growing at a rate of 4% in the world to get production and application. In recent years, the growth of PVC plastic sheet in Southeast Asia is particularly significant number of times, thanks to Southeast Asian countries have the urgent need for infrastructure construction. Among the materials that can produce three-dimensional surface films, PVC is the most suitable material. PP is polypropylene, PP chemical stability is excellent, for most of the acid, alkali, salt, oxidants are significantly inert.
PVC board molding characteristics:
1. The amorphous material, moisture absorption is small, poor mobility. In order to improve mobility, to prevent the occurrence of bubbles, plastic can be pre-drying mold casting system should be short, clear dust accessories bag dust removal accessories attention, gate section should The mold must be cooled and the surface chrome-plated.
2. Because of its corrosive and fluid characteristics, it is best to use special equipment and mold. All products should be added as needed, different types and quantities of additives.
3. Easily differentiated, at 200 degrees temperature and steel. Copper contact more easily differentiate, when the evolution of decadent decomposition. Irritant gas. Molding temperature range.
