A vibrating sand, high strength, low gas, low expansion; 2, lax, good casting surface finish; 3, can not afford to shell layer, good thermal stability, good thermal conductivity, good liquidity coated sand regeneration line manufacturers, casting surface smooth; 4, high strength, high temperature, low inflation, good mold release, anti-sticky sand is good; 5, the shell is not uniform shelling, fast curing; thermal regeneration of the basic principles is the use of the old sand boiling thermal pretreatment and regeneration furnace equipment, the first of the old sand crushing and magnetic separation vibration, and then boiling fired regenerative furnace, sand and then through the insulation, cooling, screening can reuse . After recycling the regenerated sand thermal performance up: loss on ignition (mass fraction) <0.3%; particle concentration ratio (mass fraction) 80-90%; gas evolution <3mL / g. In order to ensure the quality of coated sand core, we must first make sure that the quality of coated sand coated sand reclamation line company, various performance indicators coated sand coated sand production requirements must be met regeneration line manufacturers, the test method can be found in the machinery industry Standard (JB / T8583.1997 coated sand casting). (1) the general category of quartz sand coated sand, thermoplastic phenolic resin, methenamine and calcium stearate, without concerning additives. Generally applicable to the production of cast iron. (2) high-strength low gas class ordinary coated sand coated sand replacement products, by adding additives and use of new technology related to the preparation, its strength is higher than 30% more than ordinary coated sand, gas evolution was also significantly reduced, for the production of complex precision iron castings.
