Abstract

En våt gipsakselerator omfattende (a) et malt produkt med en midlere partikkelstørrelse på fra omtrent 0,5 mikrometer til omtrent 2 mikrometer hvori det malte produkt omfatter kalsiumsulfatdihydrat, (b) vann, og (c) minst ett tilsetningsstoff selektert fra gruppen bestående av (i) en organisk fosfonforbindelse, (ii) en fosfatholdig forbindelse, eller (iii) en blanding av (i) og (ii) er beskrevet. Også beskrevet er en fremgangsmåte for fremstilling av en våt gipsakselerator, en fremgangsmåte for hydratisering av den kalsinerte gips til å danne en forriglende matriks av stivnet gips, en stivnet gipsholdig blanding, og et stivnet gipsholdig produkt.A wet gypsum accelerator comprising (a) a milled product having an average particle size of from about 0.5 microns to about 2 micrometers wherein the milled product comprises calcium sulfate dihydrate, (b) water, and (c) at least one additive selected from the group consisting of ( i) an organic phosphorus compound, (ii) a phosphate-containing compound, or (iii) a mixture of (i) and (ii) is described. Also disclosed is a process for preparing a wet gypsum accelerator, a method for hydrating the calcined gypsum to form a locking matrix of hardened gypsum, a hardened gypsum-containing mixture, and a hardened gypsum-containing product.
