Standard of product qualityIn conformity with national standard GB9775-20088. Categorya) Common paper surface gypsum board b) Fireproof paper surface gypsum board (H) c) Waterproof paper surface gypsum board (S)Project evaluation With the popularization of application of Paper Faced Gypsum Board, its technology of it becomes more and more perfect. And the scale of production has always been large-oriented gradually. At present, the production lines of 15,000,000 M2/year have been built. 1. The production equipments must be easy to arrange into a whole production line. Except production special set parts, the rest can adopt domestic standard equipments. The driving device can also adopt domestic standard equipments. This would reduce the manufacture of nonstandard equipments; thus the production because more safe and stable. 2. Gypsum Board Production Line of 15 Million Sqm/Year possesses a moderate production scale and workshop area, this is suitable for the automatic degree, which makes it easy to control. Raw material Specification: Calcined gypsum powder Fineness 0.2mm,Remnant 10% Initial set time 3.5-5.5 minutes Final set time 7.5-10.5 minutes Crystal water 4.5%-5% Half-water gypsum powder 65% Bending strength (2 hours) 1.8 Mpa
