Product Introduction
Waterproof calcium silicate board can effectively solve the water absorption problem of insulation materials, prevent equipment and pipeline corrosion caused by a humid environment, improve insulation effect and prevent safety accidents at the same time. When in contact with water, waterproof calcium silicate boards will experience a "lotus leaf effect", causing water to condense into droplets and fall without being absorbed by the material. Waterproof calcium silicate boards are divided into two types: surface waterproof type and fully waterproof type. The surface waterproof type has a waterproof treatment on the surface of the material, but does not have a waterproof function inside. The fully waterproof material has a complete waterproof effect, and both the internal and external parts of the material have excellent waterproof performance.
