Agente de curado para la fundición de vidrio soluble y método de fabricación y uso del mismo
Un agente de curado para la fundición de vidrio soluble que comprende un alcohol, un éster, una sílice amorfa y agua; en donde la sílice amorfa es una sílice amorfa pirogénica y/o una sílice amorfa precipitada; caracterizado por que el agente de curado comprende un 20-40 % de éster, un 30-60 % de sílice amorfa; un 2-12 % de alcohol; y un 3-18 % de agua en fracción de masa; y el alcohol se selecciona de entre el grupo consistente en etanol y alcohol bencílico.
A curing agent for water glass molding comprises: ester; amorphous silica; and water. The amorphous silica is formed by means of a pyrolysis method and/or by means of a precipitation method. Also disclosed is a use of the curing agent for water glass molding in preparation of a casting mold and a mold core. Respective components of the curing agent comprising ester, amorphous silica and water are mixed at a high speed to form a suspension. Next, the suspension is applied to prepare a water glass self-hardening sand. The curing agent does not cause powder contamination, and can be measured and added conveniently. Also disclosed are a manufacturing method of the curing agent for water glass molding and a water glass self-hardening sand.
