摘要
2 1 1 6#松香改性酚醛树脂生产用多聚甲醛替代液体甲醛 ,选取最佳酚醛配比 ,缩合反应加压 ,产品颜色浅 ,质量稳定 ,生产过程污染小 ,为松香改性酚醛树脂的生产和开发拓展了新思路。
In this technology,paraformaldehyde,the best proportion of phenol and para formaldehyde,and pressure reaction were used to produce rosin phenolic resin(2116 #).The color of the product is lighter,and the most important is that the waste water of production process as well as the cost of production are hardly reduced.
