乙缩醛工艺制芯的研究

A Core-making Process Cured by Acetal

介绍一种新的气体硬化树脂砂制芯工艺——乙缩醛硬化工艺.描述了该工艺的试验装置,进行了工艺参数的选择.该工艺不向大气中排放有害物质。

A new core-making process of resin sand cured by acetal of gas-process is introduced in this uaper. The experimental equipments for this process is described and the parameters have been also tested. Because no harmful gas is separated out to atmosphere and this process is favourable to environmental protection.
