Case

Function

1) sound insulation. With sheet of double layer separate sound insulation wall and the hollow board consisting of double layer sound insulation wall, its sound insulation effect is the equivalent of about 24 cm thick brick wall, acoustic index up to 40 ~ 50 decibels

(2) fireproof. Plasterboard is noncombustible material, have certain fire performance, some can be used for fire protection of steel structure

(3)strength. When the wall of the lateral load is 250 mpa, the wall of the lateral maximum deformation is not more than 1/240 of the way up the brick wall.

(4) the humidity control. When the air humidity is bigger than its water content, plasterboard can absorb the moisture in the air; On the contrary, the plasterboard can release the moisture in plate, can adjust indoor air humidity in action.
