带表卡尺齿条与尺身的装配,在国内许多厂家都采用螺接结构,生产工艺复杂,精度要求高,故合格率低.目前国外同行业一些厂出现了以胶接代螺接的新工艺,从而简化了工艺,保证了质量.我厂从一九八一年生产带表卡尺以来,就决定对齿条尺身采用粘接工艺.经过对几种胶性能的反复试验、比较,最后选用了上海合成树脂研究所研制的SA-202胶.其试验情况小结如下:一、胶的选择:主剂:SA-202胶 上海合成树脂研究所生产外观:淡黄色乳状或半透明粘稠液体
With table caliper rack and the assembly of the body, many manufacturers in the country are using the screw structure, the production process is complex, high precision, so the pass rate is low. At present, some factories in the same industry with the glue to replace the new Process, thus simplifying the process, to ensure the quality of our factory from the production of table calipers in 1981, decided to stick to the rack body using adhesive technology.After repeated tests of several adhesive properties, compared to the last The selection of the SA-202 plastic developed by Shanghai Synthetic Resin Research Institute.The test results are summarized as follows: First, the choice of plastic: The main agent: SA-202 plastic Shanghai Synthetic Resin Institute Appearance: light yellow milky or translucent viscous liquid
