为解决某型机机翼整体油箱用密封剂对阳极化时间较长的铝合金、镁合金、不锈钢粘接差而造成的渗、漏油问题，采用我国粘接底涂ＱＳ－７进行了一系列试验和装机试用，证明粘接底涂ＱＳ－７能显著提高密封剂对各种材质的粘接能力，且使用工艺简单，不增加辅助器材。系列的试验及装机试用证明，采用该底涂是一种理想而可靠的方法
In order to solve the problem of seepage and oil leakage caused by poor bonding of aluminum alloy, magnesium alloy and stainless steel with a long time of anodizing, Series of tests and installed pilot trial to prove that bonding primer QS-7 can significantly improve the sealant adhesion to various materials, and the use of simple technology, without increasing auxiliary equipment. Series of experiments and installed pilot proved that the use of the primer is an ideal and reliable method
