Selection of precoated sand is a kind of high quality natural sand is sand base, with special properties of the resin coated system and optimal technology, according to the technical requirements of different users, aiming at room temperature performance, high temperature performance, melting, liquidity and casting surface roughness, etc, the perfect combination, is widely used in automobile engine, diesel engine, hydraulic parts, etc.
Before molding sand surface that has a solid resin film layer of sand and core sand. With cold and hot hair two laminating process: cold ethanol dissolve resin, and join in the process of sand methenamine, make both coated on the surface of the sand, ethanol volatilization, coated sand; Thermal method adding sand preheated to a certain temperature, resin melt, stirring make the resin coated sand surface, methenamine aqueous solution and lubricant, cooling, crushing, screening of precoated sand. Used for steel, cast iron pieces.
Mainly adopts the high quality of precoated sand selected natural quartz sand as the original sand, thermoplastic phenolic resin, methenamine and strengthening agent as raw materials. According to the different technical requirements of users, the curing speed, membranous, liquidity, melting, casting surface roughness ratio of appropriate adjustments, storage, etc. Are cars, tractors, hydraulic parts, etc. One of the best molding materials.
