Production process
Prepare material (Tobermorite crystal , fly ash, Quartz sand, cellulose fiber…) →loose fiber→ blending (15 minutes) → blowing→forming in 1 time(Hatschek process)→ stacking(usually model by model)→ pressurization (in order to make the fiber well-knit through evaporation with 4000 tons press machine for 15 minutes) →nature conservation(make the boards have the prime strength)→mold release→ steaming (1 standard atmosphere pressure for 24 hours )→prime checking→ sanding →edge trimming →packing→ quality inspection→ warehousing
Fiber Cement Board
is mainly made of Portland cement and silicate materials as base and cellulose reinforced, forming in Hatschek process and high pressure (4000T press machine for 15 minutes) and fumigation(in autoclave for 24 hours)，so it has the advantages of high strength, light weight, 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, billboard, external wall panel, exterior wall cladding, paneling, moving floor, desktop board, fire-resistant air pipe , 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.
