The average output and consumption of PVC Tong Ming board is one million and four hundred thousand tons, which is being exported and utilized on a global scale at a rate of 4%. In recent years, the increasing number of PVC plastics in Southeast Asia is particularly obvious. This is due to the urgent need for Southeast Asian countries to stop infrastructure support. The material can produce a three-dimensional film, PVC plastic plate is the most appropriate information. Specific gravity: 1.38 g / cubic centimeter, molding compression rate: 0.6-1.5%, molding temperature: 160-190 C.
Features: mechanical function, excellent motor, strong acid and alkali resistance, good chemical stability, low hardening point. It is suitable for making thin plates, wire and cable insulation, seals and so on.
The molding features of the plastic sheet are:
1. unshaped material, small moisture absorption, poor fluidity. In order to improve liquidity, avoid producing bubbles, plastic can be dry afterwards. Mold casting system should be short, gate section should be large, no dead bath board
The mold must be cooled and chrome outside.
2., because of its characteristics of corruption and mobility, the best equipment and mold should be adopted. All products must be attended to different kinds and quantities of auxiliaries according to necessity.
3., it is easy to differentiate. At 200 degree temperature, it is easier to fight with steel and copper. When it breaks away, it will escape and decay.
4. when adopting the screw type injector nozzle, the aperture should be large, so as to avoid dead angle and sluggish. With or without insert, if the insert is preheated, it should be preheated.
PVC board can be seen everywhere in people's daily life. PVC can not only express the colors of nature, but also express the colors of people's ideals.
