近几年,铸件生产厂在环境和技术上需要的投资已越来越迫切。这一趋势有可能延续至90年代。铸造工作者已采用了多种冷制芯工艺,但是,除了水玻璃二氧化碳硬化法以外,其他的有机粘结剂工艺都有着环境污染和冶金方面的问题。尽管水玻璃二氧化碳硬化法无环境污染,但是在强度和铸件的落砂上受到了一定的限制,即使是最新专利——水玻璃二氧化碳粘结剂也不能与有机粘结剂的性能相比。 ECOLOTEC粘结剂工艺是随着铸造工业中来自环境方面的压力不断增加而得到发
In recent years, investment in the casting plant needs to be environmentally and technically more and more urgent. This trend is likely to continue into the 90’s. Foundry workers have adopted a variety of cold core processes, however, other organic binder processes besides water glass carbon dioxide have environmental pollution and metallurgical problems. Although sodium silicate carbon dioxide has no environmental pollution, it has some limitations on strength and casting sand, and even the latest patent-sodium silicate binder can not be compared with organic binders. The ECOLOTEC binder process is developed as the pressure from the environment in the foundry industry continues to increase
