use | as a vapor phase corrosion inhibitor. It is mainly used for metal corrosion inhibition protection and preventing the continuation of metal corrosion. Such as used in automobiles and auto parts, deceleration chassis, internal combustion engines, machine tools, cutting tools and measuring tools, etc., can also be used for metal protection of weapons, radars and other equipment. Gas phase corrosion inhibitor has excellent performance, long anti-rust period, good anti-rust effect, complex and simple parts are suitable. But it has a corrosive effect on brass, tin and their alloys. |
Production method | The reaction of dicyclohexylamine and phosphoric acid produces dicyclohexylamine phosphate, and then sodium nitrite is added to react to produce dicyclohexylamine nitrite: The reaction product is washed and dried to obtain the finished product. |
