Abstract

En forbedret gipsslurry som inkluderer vann, kalsiumsulfat hemihydrat, et polykarboksylat dispergeringsmiddel og en modifiserer. Modifisereren er kjemisk konfigurert for å forbedre virksomheten av polykarboksylat dispergeringsmidlet. Foretrukne modifiserere inkluderer sement, kalk, lesket kalk, kalsinert soda, karbonater, silikater og fosfater.An improved gypsum slurry which includes water, calcium sulfate hemihydrate, a polycarboxylate dispersant and a modifier. The modifier is chemically configured to improve the activity of the polycarboxylate dispersant. Preferred modifiers include cement, lime, lime, calcined soda, carbonates, silicates and phosphates.
