Light Weight Fireproof Calcium Silicate Board -Tunnel

calcium-silicate-board1

 

Raw material : Pure quartz powder , quick lime , Portland cement , cellulose and some kinds of fined mineral additives

including suspending additive . We make the raw material into a wet sheet and then through high temperature and high

pressure autoclave for more than 10 hours by advanced technology to have the final product . It will compose a special

Calcium Silicate Board .

There is no asbestos , brucite and meerschaum in the raw materials and the formulation at all .

 

Advantages :

Light Weight Fireproof Calcium Silicate Board

1.Through-coloured base board ,with coliured varnish which gives a natural appearance .
2. Durable . More than 60% of the composition is same as granite , more than 20% same as marble .
3.High strength , good at impact resistance .
4. Resistant to high tempeartures
5. Excellent weather resistance , water resistant
6.Outstanding sound insulation capability .
7.Non combustible , no flame spread , no fune development , no toxic gasses
8.Low moisture and water absorption.
9.Resistant to fungus, bacteria , insects , vermin, etc.
10.It is non-radioactive.
11. Resistant to many chemicals
