Characteristics of sanding board fireproof floor

1. Fireproof and flame retardant.

Glass magnesium plate is a non combustible material tested by national authorities. The fire resistance limit of the wall and steel structure composed of it is much higher than the national standard.

2. Waterproof and moisture-proof.

After one month of immersion, the sanding plate still maintains its original state and will not deform and swell. Its dry and wet deformation rate is 0.26% and water absorption is about 15%. Specifically, the flexural strength is 18pa in dry state and 22Mpa in hygroscopic state, that is, it is stronger in hygroscopic state.

3. Sound insulation.

Sound insulation effect is good.

4. Insulation and heat insulation.

The thermal resistance coefficient of sand is 1.14m2 K / W, with good heat insulation and thermal insulation performance.

5. Light weight and high strength.

The 10mm thick wallboard weighs 8.8kg/m2, about 1 / 10 of the general solid clay brick wall, and its impact strength is 2 ~ 3 times higher than that of ordinary gypsum board wall. It is easy to install and can effectively shorten the construction period.

6. Green environmental protection.

This is a new type of inorganic substance The radioactivity of plant fiber and other natural materials is far lower than the national standard, and the environmental protection meets the new products encouraged by the national policy.
