Title (EN) CURING AGENT FOR WATER GLASS MOLDING AND MANUFACTURING METHOD AND USE THEREOF
(FR) AGENT DURCISSEUR DESTINÉ AU MOULAGE DE VERRE SOLUBLE ET SON PROCÉDÉ DE FABRICATION ET SON UTILISATION
(ZH) 一种铸造水玻璃用固化剂及其制备方法和用途
Abstract:
(EN) 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.
(FR) L'invention concerne un agent durcisseur destiné au moulage de verre soluble, comprenant : un ester ; de la silice amorphe ; et de l'eau. La silice amorphe est formée au moyen d'un procédé de pyrolyse et/ou au moyen d'un procédé de précipitation. L'invention concerne également une utilisation de l'agent durcisseur destiné au moulage de verre soluble, en préparation d'un moule de coulée et d'un noyau de moule. Les constituants respectifs de l'agent durcisseur comprenant un ester, de la silice amorphe et de l'eau sont mélangés à grande vitesse de manière à former une suspension. Ensuite, la suspension est appliquée de manière à préparer un sable autodurcissant de verre soluble. L'agent durcisseur ne provoque pas de contamination de poudre et peut être mesuré et ajouté de manière pratique. L'invention concerne également un procédé de fabrication de l'agent durcisseur destiné au moulage de verre soluble et un sable autodurcissant de verre soluble.
(ZH) 一种铸造水玻璃用固化剂,包含:酯、无定形二氧化硅和水,无定形二氧化硅为热解法无定形二氧化硅和/或沉淀法无定形二氧化硅。还公开了一种铸造水玻璃用固化剂在制备铸型和型芯中的用途,将包含酯、无定形二氧化硅和水的固化剂各组分高速混合配制成悬浮液,再将其应用于水玻璃自硬砂的制备中,无粉体污染,计量、添加方便。还公开了一种铸造水玻璃用固化剂制备方法和一种水玻璃自硬砂。
