摘要
采用改性有机硅树脂对呋喃树脂进行改性,提高了树脂砂常湿及高湿强度;降低了树脂加入量,减少了发气量和刺激性气味,减少了环境污染;降低了成本。
As the modifying organic silicone resin was used to modify the furan resin,It resulted in better normal wet strenth and high wet strength of resinbonded sand,reducing resin addition,reducing gas generating and irritation, improving enviromental pollution as well as lower costs of production.
