Calcium Silicate Board

Calcium Silicate Board is mainly made of Portland cement and silicate materials as base and cellulose fiber strengthen, forming in Hatschek process and high pressure (4000 tons and fumigation(in autoclave for 24 hours),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. Applications: Business building, Entertainment facility, supermarket, hotel & restaurant, factory, warehouse, apartment building, hospital, theater and station etc. The size: 1220x2440x5mm-30mm (4'x8'x5mm-30mm)Materials: Tobermorite, CaO, Quartz sand, cellulose fiber Fire-proof rate: A-class incombustible (GB8624-1997) Incombustibility: 180 minutes (GB/T9978-1999) Density: 1.20-1.50g/cm3 Moisture: <10% Heat conduction: 0.24W/MK (Jc/t564) Average Sound-absorption: 45db (GBJ75-84) Anti-bend strength: >15MPa (GB/T7019-1997) Moisture movement rate: <0.19% (GB/T7019-1997) Dry shrinking rate: <0.09% (GB/T7019-1997) Radiation rate: According with Standard (GB6566-2000) 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
