Generally speaking, the high-performance cement fiber board meeting the building requirements and national standards needs to meet the following conditions to be considered as the high-performance standard fiber cement pressure plate.

First of all, the fire insulation standard should meet the class a standard of non combustion. When the fire occurs, the fiber cement board will still not burn, and will not produce toxic smoke and fog, and the conductivity level is very low. At the same time, it should be waterproof, moisture-proof and moisture-proof. Even if it is placed in the semi open air or high humidity environment, the performance of the board will still be stable, and there will be no subsidence or deformation. In terms of strength, the general fiber cement board has been pressed and forged by about 5000 tons of plate hydraulic press, with high strength, which is neither easy to deform nor warped.

Secondly, the length, height, thickness, right angle and overall dimension should meet the requirements of the architectural design.

Third, the degree of color should be in line with the design requirements of the building party, and it is required to maintain the consistency of the color allocation of each board, and there should be no obvious color deviation.

Fourth, the surface of fiber cement pressure plate should be machined. The processed surface plate needs to be washed with high-pressure water, or cleaned carefully with water and soft brush. The solvent type chemical cleaner can not be used to clean the plate.

Fifthly, the technical requirements and performance of the metal pendant used on the decorative surface should fully comply with the current national technical standards.
