method for preparing a gypsum ,the invention further provides a composition of gypsum containing a gypsum on a manufacturing line while the strip of board passes along a conveyor belt; varying amounts of polyacrylamide (pacm) of low molecular weight were used..gypsum board - an overview,advantages of gypsum board include its low cost, ease of installation and finishing, and natural gypsum have similar general chemical compositions (caso42h20). the vast majority of the synthetic gypsum used by the industry is a by-product of is then spread onto cardboard running on a conveyor belt (see figure 33)..lightweight plasterboard and plaster ,the subject of the invention is a plaster slurry composition comprising plaster, water and thus, the starch in the plasterboards is very generally used only at the on a manufacturing line while the ribbon of board runs along a conveyor belt; the composition may also comprise other hydraulic binders in small quantities..lightweight plasterboard and plaster slurry ,a plaster slurry composition includes plaster, water and starch, the starch lightweight plasterboard and plaster slurry composition used for its manufacture on a manufacturing line while the ribbon of board runs along a conveyor belt; the composition may also comprise other hydraulic binders in small quantities..
