Introduction Of PVC Sheet Forming Characteristics
- Nov 20, 2018 -

PVC sheet is made of hard PVC, which is waterproof, moisture-proof and anti-mite. It contains flame retardant raw materials, so it is safe to use. Most of the PVC plastic sheets are mainly plain, and there are also imitation patterns and imitation marble patterns. Its cross-section is a honeycomb-like mesh structure, and there are processed tongues and concaves on both sides. This is the detail of the selection. It requires the tongue and the groove to be straight and straight, and the bite is smooth and the parts are free from undulations and height differences. PVC plastic panels vary from 12 to 20 yuan per square meter, which is affordable. PVC plastic plate 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, seals, etc. Its global usage is in each Among the synthetic materials, it ranks second. PVC is being produced and applied worldwide at a rate of 4%. In recent years, the growth of PVC plastic sheets 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 is the most suitable material. PP is polypropylene, PP has excellent chemical stability and is inert to most acids, bases, salts and oxidants.

PVC sheet molding characteristics:

1. Amorphous material, low moisture absorption, poor fluidity. In order to improve fluidity and prevent the occurrence of bubbles, the plastic can be pre-dried. The mold casting system should be short and thick, and the dust-proof accessory bag type dust-removing accessories should be removed. Big, 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 amounts of additives as needed.

3. It is highly diversified, and it is more easily differentiated from steel and copper at 200 °C, and it is eroded during differentiation. Irritant gas. The molding temperature range is small.
