How to distinguish the quality of PC hollow boards?
1. By the transparency
The transparency of the hollow board with a long warranty period is about 94%. The lower the transparency, the more the recycled material will increase, and the color of the defective boards will be black.
Spread the protective film to see the plate. The non-impurity and non-particulate sheet is a new material. On the contrary, the foreign matter with impurities is added to the recovered material. The more the recycled material is added, the more the impurities are, the more the quality of the sheet is worse.
2. By the thickness of the upper and lower walls
The thicker the thickness, the more the material is used, the higher the specific gravity, the higher the cost, and the better the quality of the sheet. This method is also the same as the method of weighing the sun panel per unit area. Bending the sun plate sample, the poorer the quality of the fragile plate, the polycarbonate board have better tolerant, if the board is very simple cracking, it is not pure PC materials, that is the hollow sheet was added the reclaim material.
3. By the flatness of the board
On the one hand, the flat plate clarifies that the upper and lower walls are thicker, and the material is not easy to be deformed. On the other hand, the equipment process is also better. If the plate has waves, it is clear that the solar panel process is not sophisticated or the upper and lower walls are relatively thin.
4. By the price
The same kind of standard hollow board, not the same brand hollow board price distance is too large, the low price of the hollow board must have problems.
