用水玻璃粘合砂芯,不仅适用于干型油砂芯,而且还可用于干型组合砂芯。用它粘结后强度高,质量好,是一种代替面粉、糊精节约粮食的较好粘结剂,现将粘结工艺介绍如下: 1.将已烘干的油芯2、4(见图1),在其接合处相互摩擦转动,然后分开吹净接合面处砂尘,将油芯1放在转盘(图2)上。

Water glass bonded sand core, not only for dry oil sand core, but also for dry combined sand core. Use it to bond high strength, good quality, is a good alternative to flour, dextrin better food binder, the bonding process is as follows: 1. The dried oil core 2,4 (see Figure 1), at their joints rubbing and rotating with each other, and then blow away the dust at the junction surface, the oil core 1 on the turntable (Figure 2).
