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
