| 摘 要： | 由于催化剂中含有一定量的活性物质(对甲醛),从而降低了磺酸的浓度、也就是减少了硫的含量,改善了树脂砂的使用环境。试验分两批进行。第一批所采用的催化剂有十六种,其代号、组成、树脂砂性能见表1。第二批试验所采用的催化剂有二十二种,试验结果见表2。为了例于比较,表2中一部分催化剂同表1。

| Abstract: | Various catelysts were investigated in this arti- cle in terms of the strength of phenolic resin bonded sand. The behaviour of the catalysts for the resins was discussed. A method of evaluation of the effi- ciency of the catalysts was proposed. Aseries of new kinds of phenolic catalysts were given firstly in this paper. They could eliminate the irritating odour during sand mix preparation and decrease smoke e- volved from phenolic resin bonded sand when pour- ing molten metals. |
