青岛日用化工厂在煤炭科学院北京所的协助下,结合我国具体情况,参考国内外汽车水箱防冻防锈冷却液的产品及资料,研制成功了一种新型汽车水箱用30~#～40~#防冻防锈冷却液。这种冷却液除具有良好的冷却效果之外,还具有30~#冷却液在不低于-25℃、40~#冷却液不低于-35℃不结冻及对水箱具有足够的防锈等特点。它的组成以乙二醇为主,添加少量我国新试制成功的特效防锈剂——硼酸鋰皂以及对铜件有独特防锈效果的苯并三氮唑,并添加有硬水络合剂。产品为萤光红色透明液体。
With the help of Beijing Institute of Coal Science and Technology, with reference to the specific conditions of our country and with reference to the products and materials of antifreeze antirust coolant at home and abroad, Qingdao Daily Chemical Factory succeeded in developing a new type of automotive water tank with 30 ~ # ~ 40 ~ Antifreeze anti-rust coolant. In addition to this cooling fluid has a good cooling effect, but also has 30 ~ # coolant at not less than -25 ℃, 40 ~ # coolant is not less than -35 ℃ not frozen and the tank has enough rust Features. Its composition is mainly ethylene glycol, adding a small amount of our new trial success special effects rust inhibitor - lithium borate soap and copper has a unique anti-rust effect of benzotriazole, and add a hard water complexing agent. Products are fluorescent red transparent liquid.
