1. the thickness 15mm with fireproof performance only reach the request of B1 grade
2. its hydroscopic is heavy, it is apt to out of shape.
3. the board is taken as rigidity, it is unable to do the modeling crookedly.
4. the processing two times is difficult, superficial laminating is not good, decorated layer is unable to paste
5. weight is heavy, it is strenuous to carry, and the damaged rate is high.
6. intensity low, poor to be able to bare climate, afraid of being collided, afraid of water, afraid of damp, and out of shape seriously when being stained by water
1 .The thickness above 6mm can reach the request of A grade and the material that is not fired.
2 expansion of coefficient is about 8/10000, absorbing water rate of is slight high (absorbing water rate is 35%)
3. the board is taken as rigidity, it is unable to do various types of modeling crookedly.
4. general construction way only being taken, difficult to be covered on the surface.
5. weight is relatively heavy, it is strenuous to carry, and the damaged rate is high.
6.contain the asbestos in most products
1.3mm thickness to the request of firing prevention.
2.able to bear the damp well, not out of shape, anti-halogen.
3.can stick to, cut down, nailing, gluing, paint, saw, lane, and can use the art designing knife to construct.
4. the board body is pliable and tough and flexible, can crookedly.
5. can collocate various types of panel, make up skin or log skin engaged in the processing two times.
6. light weight, conveniently carry, low damaged rate, waterproof, damp proof.
