Why PVC board can develop rapidly in Europe

Date:2016-07-27 Author: Click:

In Germany, the average production and consumption of PVC board is one million and four hundred thousand tons. PVC is at a 4% growth rate in the world within the scope of production and application. In recent years, the growth of PVC board in Southeast Asia is particularly significant, thanks to the urgent need for infrastructure development in Southeast Asian countries. PVC plate is the most suitable material for producing three dimensional surface film. The specific gravity is 1.38 g / cubic centimeter, the molding shrinkage is 0.6-1.5%, and the molding temperature is 160-190 C.

PVC plate forming characteristics:

1., it is easy to decompose. At 200 degree temperature, contact with steel and copper is easier to decompose. When it decomposes, it escapes and corrode. Irritating gas. The forming temperature range is small.

2. when screw injector is used, the diameter of the nozzle should be large enough to avoid dead angle. If the inserts are used, the insert should be preheated.

3. amorphous material, small moisture absorption, poor fluidity. In order to improve the fluidity, prevent the occurrence of bubbles, plastic can be dry in advance. Mold casting system should be short, gate section should be large, no dead angle. Mould must be cooled, surface chrome plating.

4., because of its corrosive and fluidity characteristics, it is better to use special equipments and moulds. All products must be added different kinds and quantities of auxiliaries according to needs.

The full name of PVC board is Polyvinylchlorid, the main component is PVC, the color is bright, corrosion resistant and durable. Because of the addition of some toxic auxiliary materials such as plasticizer and antiaging agent to enhance its heat resistance, toughness, ductility and so on in the manufacturing process, its products do not store food and medicine in the same way.

PVC board is a kind of synthetic material popular and popular in the world today. Its global usage is second higher in all kinds of synthetic materials. According to statistics, in 1995 alone, the output of PVC board in Europe was about five million tons, while its consumption was five million and three hundred thousand tons.
