我厂主要生产小型制冷设备和1～5~＃电动机,铸铁牌号为HT15-33和HT20-40两种。最大壳体铸件重40kg,最小的油盖0.5kg。大部分是潮模湿芯,全部是手工操作。厂部规定铸件质量指标86％(包括外废2％)。为了挽回废品损失,我们开始用“铸308”纯镍生铁焊条焊补,但成本偏高(每公斤78元)。后来,学习了兄弟厂家粘接技术的先进经验,结合我厂的具体条件,采取焊接和粘接并用,达到了预期的目的。一、使用范围和特点 HY-914粘接剂对金属、陶瓷、玻璃、木材、胶木等材料都有较好的粘接力,可用在±60℃条件下使用的金属和一些非金属部件的小面积快速粘接(但不能粘接聚烯烃塑料和承受大冲击力的部件)。作为铸铁件缺陷修复,
I plant mainly produces small refrigeration equipment and 1 ~ 5 ~ # motor, cast iron grades HT15-33 and HT20-40 two. The largest shell castings weighing 40kg, the smallest oil cap 0.5kg. Most of the wet mode moist core, all by hand. Factory regulations casting quality indicators 86% (including 2% of waste). In order to restore the waste loss, we began to use “cast 308” pure nickel pig iron welding, but the cost is high (78 yuan per kilogram). Later, I learned the advanced experience of the bonding technology of brother manufacturers, combined with the specific conditions of our factory, to achieve the expected purpose by welding and bonding. First, the use and characteristics HY-914 adhesive on the metal, ceramic, glass, wood, bakelite and other materials have better adhesion, can be used at ± 60 ℃ under the conditions of the metal and some non-metallic parts of the small Quickly bonded area (but can not be bonded polyolefin plastic and withstand high impact parts). As a cast iron defect repair,
