９４─０３９防止腐蚀的汽车冷却液非腐蚀性的汽车冷却系统用的防冻液，包括防止腐蚀有效量的硅酸钠缓蚀剂和硝酸钠。硅酸钠通常具有低的氧化硅／氧化钠比率，＞１．０～２．４：１，最好是１．５～２．０：１。当含这种缓蚀剂的醇基防冻液，其硅酸钠和硝酸钠的协同作用保...
94-393 Preventing Corrosion of Automotive Coolants Antifreeze for use in non-corrosive automotive cooling systems, including corrosion inhibitors and sodium nitrite in an amount effective to prevent corrosion. Sodium silicate generally has a low silica / sodium oxide ratio> 1.0 to 2.4: 1, preferably 1.5 to 2.0: 1. When the alcohol-based antifreeze containing this inhibitor, its synergistic effect of sodium silicate and sodium nitrate ...
