有机粘结剂所具有的高生产率、旧砂回用率,以及获得铸件良好的表面质量等,使其得到越来越广泛的应用,但其价高特别是产生的大量气体所带来的铸件气孔、脉纹等缺陷,以及污染环境等问题,与绿色铸造又格格不入。而传统的无机粘结剂,特别是水玻璃虽适应了绿色铸造的趋势,但铸件表面质量差及回收利用难题却长期困扰着铸造工作者。
The high productivity of organic binders, the rate of reuse of used sand, and the good surface quality of the castings make them more and more widely used, but the high cost of castings, especially the large amounts of gas produced Pores, veins and other defects, as well as pollution of the environment and other issues, and green casting are out of tune. While traditional inorganic binders, especially water glass, have adapted to the trend of green casting, the problems of casting surface quality and recycling have long plagued foundry workers.
