PVC hardboard is usually made of rolled PVC sheet by superimposed heating and pressing. Grey PVC Rigid Boards.
Brife Stages of Grey PVC Rigid Boards Making :
1. Low temperature heating stage
2. Medium temperature heating stage
3. High temperature heating stage
4. Stop Heating Adjustment Phase
5. Cooling stage
The Influence of Repression Time of Grey PVC Rigid Boards:
Grey PVC Rigid Boards is usually made of rolled PVC sheet by superimposed heating and pressing. According to the need, this kind of PVC hardboard can be flexibly made into various thicknesses. Because PVC is a thermo-unstable resin, HCl is decomposed and polyene structure is formed by thermal decomposition. If processed at high temperature for a long time, the product performance will be seriously affected. However, PVC is also a poor heat conductor, heat transfer is slow, to prepare products with good performance, heating time is difficult to control, such as insufficient heating time, easy stratification in the board; if heating time is too long, not only reduces production efficiency, more serious is that PVC will accelerate decomposition at high temperature for a long time, thus affecting product performance.
