What is the drawback of the gypsum board?
After flooding easy to yellow, careful water is no problem
Moisture resistance is poor, and sometimes easy to crack, will see the rust inside the nails, so pay attention to moisture, decorative row of nails must use stainless steel.
Poor moisture resistance, easy to crack.
Gypsum board to build gypsum as the main raw material, the general manufacturing can be mixed with light materials, made of hollow or the introduction of foam to reduce the weight and reduce the thermal conductivity; can also be incorporated into the fiber material to improve the tensile strength and reduce brittleness; Can be mixed with silicon mineral powder or organic waterproofing agent to improve its water resistance; sometimes the surface can be sticky or aluminum foil to increase the appearance and moisture resistance. Gypsum board is characterized by light, adiabatic, non-combustible, can be sawing nails, sound absorption, humidity, beautiful. But poor moisture tolerance. Gypsum board is mainly used for interior walls and flat roof decoration, isolation wall, insulation materials, sound-absorbing materials, wood and other materials.
