Gold Bond High Strength LITE Gypsum Board is drywall that is formulated to be 25% lighter than standard 1/2" drywall The result is a superior board that is lighter in weight sag resistant and easier to handle High Strength LITE drywall can be used for walls and ceilings in non fire rated single layer construction where framing members are
·This paper introduced the characteristics of α high strength gypsum preparation from FGD gypsum by autoclaved semi dry process The compositions of the product in different stages of the reaction and the effects of crystal modifiers on the morphology of the α HH crystals were examined and compared The properties of α HH and the feature of hydration products of
·Key words Nitrophosphate Ammonia neutralization Deep decalcification High strength α hemihydrate gypsum Controlled crystallization at atmospheric pressure ： The freezing acidolysis solution of the nitric acid phosphate fertilizer process has a high calcium content which makes it difficult to produce fine phosphate and high water soluble phosphate
3 ·30% lighter than standard 5/8 Type X gypsum board Approved component in specific 30 minute UL fire rated designs Gold Bond® High Strength Fire Shield 30® Gypsum Board consists of a fire resistant non Type X gypsum core specially formulated to be 30% lighter than standard Type X gypsum board
This paper introduced the characteristics of a high strength gypsum preparation from FGD gypsum by autoclaved semi dry process The compositions of the product in different stages of the reaction and the effects of crystal modifiers on the morphology of the a HH crystals were examined and compared
·More importantly the prepared α HH was high strength gypsum >30 MPa with high added value Therefore our research has achieved the synchronization of deep phosphorus removal and preparation of high value added gypsum products from PG under mild conditions at laboratory scale thus providing an innovative approach for clean utilization of
·The high strength α hemihydrate gypsum is widely recognized as a high value added cementitious material for its superior workability high strength and favorable biocompatibility [17 20 21] Different crystalline forms of α hemihydrate gypsum have different gel strengths The needle shaped α hemihydrate gypsum has the lowest strength
·Using FGD gypsum as the raw material short columnar shaped α calcium sulfate hemihydrate can be prepared with succinic acid in hydrothermal autoclave method with a low salt content Preparation of Large Grained α High Strength Gypsum with FGD Gypsum Duoduo Shao Duoduo Shao Chemical engineering institute Hebei University of Technology
