Production process
Â
Prepare material (Tobermorite
crystal , fly ash, Quartz sand, cellulose fiber…) →loose
fiber→ blending (*5 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 ***0 tons press machine
for *5 minutes) →nature conservation(make
the boards have the prime strength)→mold release→
steaming (1 standard atmosphere
pressure for *4 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 (***0T press machine for *5 minutes)
and fumigation(in autoclave for *4
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.Â
