Detailed Product Description

    Calcium Silicate Board is mainly made of Portland cement and silicate materials as base and cellulose fiber strengthen, forming in one time with high pressure (4000 ton) and fumigation(autoclave),Which has the advantages of high strength, anti- freeze, water-resist, fire-proof, damp-proof, sound-absorption , no distortion and no radiation...Etc. Used as suspended ceiling, partition, heat insulating board, base plate, external wall panel, exterior wall cladding, paneling, flooring, back-liners, skirting lines, prefabricated structures, door shutters etc.  

For example: Business building, Entertainment facility, supermarket, hotel & restaurant, factory, warehouse, apartment building, hospital, theater and station etc.

Production process

Prepare material (Tobermorite, fly ash, Quartz sand, cellulose fiber) →loose fiber→ blending (15 minutes) → blowing→ forming in 1 time→ stacking(usually model by model)→ pressurization (in order to make the fiber well-knit through evaporation with 4000 tons press machine in 15 minutes) →nature conservation(make the boards have the prime strength)→mold release→ steaming (1 standard atmosphere pressure with 24 hours )→prime checking→ sanding →edge trimming →packing→ quality inspection→ warehousing
