Gypsum admixture for polycarboxylic ceramic dies for compounding arylsulphobetaine
The invention discloses a gypsum admixture for polycarboxylic ceramic dies for compounding arylsulphobetaine. The arylsulphobetaine can be combined with Ca<2+>, so that a hydration process can be accelerated to a certain extent, thereby slowing down the delayed coagulation of a polycarboxylic macromolecular admixture. By adding a small amount of arylsulphobetaine into the polycarboxylic macromolecular admixture, a gypsum admixture for polycarboxylic ceramic dies, which can reduce the water-gypsum ratio, and does not reduce the water imbibition of gypsum on the premise of enhancing the strength of gypsum for ceramic dies, can be obtained. After the gypsum admixture is added into beta-hemihydrate gypsum, the water-gypsum ratio can be reduced, thereby facilitating the improvement of the strength of ceramic gypsum dies, and then facilitating the improvement of the number of use and production efficiency of dies for ceramic production.
