fibre cement board

Fiber Cement Board is mainly made of Portland cement and silicate materials as base and cellulose fiber reinforced, forming in Hatschek process and high pressure (4000 tons press machine in 15 minutes) and fumigation(in autoclave for 24 hours),so it 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, 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. We can produce the size :1220x2440x5mm-30mm (4'x8'x5mm-30mm)Materials: Tobermorite, Portland cement, Quartz sand, cellulose fiber Fire-proof rate: A-class incombustible (GB8624-1997) Incombustibility: 180 minutes (GB/T9978-1999) Density: 1.30-1.50g/cm3 Moisture: <10% Heat conduction: 0.24W/MK (Jc/t564) Average Sound-absorption: 45db (GBJ75-84) Anti-bend strength: >16MPa (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)
