中国胶粘剂

分析了化学氧化表面处理中化学处理温度、化学处理时间、化学处理液使用次数和处理后试片存放方式等因素对胶粘剂剪切强度检测结果的影响。研究结果表明：当化学处理温度在70℃左右，化学处理时间控制在10～30 min之间，化学处理液最多使用2次，并且处理干燥后的试件在4 h内完成粘接的条件下，铝合金粘接效果较佳。

The influence of chemical treatment temperature,chemical treatment time,the number of times of using chemical treatment solution and the storage mode of treated specimen in chemical oxidation surface treatment on test results of adhesive shear strength was analyzed. The research results showed that the bonding effect of aluminum alloy was relatively good when the chemical treatment temperature was around 70 ℃,the chemical treatment time was controlled between 10-30 min,the chemical treatment solution was used at most 2 times,and the bonding of the treated and dried specimens were completed within 4 h.
