?????? Calcium Silicate Insulation Board is a new –style white and hard insulated material, which has the characteristics :
?????? 1.small bulk density,?
???? ? 2.high strength and low thermal conductivity.
?????? 3. It can bear high temperature and corrosion, tools can optional cut them.
?
????? The basic material of calcium silicate board is silica and calcium powder, its reforced material is natural woody fibre, then adding a small amount of additives as well as a large amount of water, after reasonable ingredients, heat of mixing rubber, molding steam, curing crystallization and drying processes, then produce the new building material.????
