creases with the increase of temperature. The mechanical properties of rigid PVC are good, and its elastic modulus can reach 1500-3000MPa. The soft PVC has an elasticity of 1.5-15 MPa. The friction of PVC is generally, the static friction factor is 0.4-0.5, and the dynamic friction factor is 0.23. PVC sheet is basically divided into PVC hard board, PVC soft board and PVC transparent board.
1, PVC hard board appearance: smooth surface, smooth, no cracks, no bubbles. The color is generally gray, white, and can be used for blue, black, and micro-machine color; PVC hard board is processed into various acid-resistant and alkali-resistant chemical equipment. Widely used in chemical, electroplating, smelting, water treatment industries, PVC fabrics used in the construction and decorative materials industry as a template, the demand is very large. But it is not suitable for food containers.
2, PVC soft board: PVC is added to the flexible sheet of plasticizer and other auxiliary materials.
Soft board appearance: The surface is smooth and flat, and the texture is soft and tough. The colors are white, green, red, gray, black and so on.
Use; It is used for lining of acid and alkali resistant and anti-corrosion equipment. It can also be used as general electrical insulation and sealing gasket. The use temperature is -20~40 °C.
3, PVC transparent hard board, the surface is smooth and flat, with flame retardant, insulation, moisture, heat, corrosion, impact resistance, no deformation, anti-light, anti-fading, good weather resistance and so on. Widely used in shockproof, anti-corrosion containers, equipment electrical shields, light boxes, construction, hardware decoration and interior and exterior decoration.
4, PVC transparent soft board, smooth surface, no cracks, no bubbles, uniform color, cold-resistant, heat-resistant, anti-aging, tensile, light transmission, long service life, etc., can be used as a civil decoration, but also As an industrial board, it is mainly used in shops, shopping malls, factory aisle curtains, table tops, etc.
