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 15minutes)→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
