The Research on Film-Forming Performance of a New Kind of Compound Inhibitor

Abstract

The film-forming effect of a new kind of compound inhibitor at high temperature was researched, with taking pure octadecyamine and pure imidazoline as comparison tests. Coupon test has been taken with autoclave simulating the on-site water-vapor environment; the film-forming effect of the coupon has been evaluated by hydrophobic test, acid copper sulfate drip test ,AC impedance test and scanning electron microscope(SEM) test. The GC-MS test was taken to analysis decomposition products of the compound inhibitor. The results show that the compound inhibitor can film well, and decomposition product doesn’t contain low molecular weight organic acids and other harmful ingredients. The compound inhibitor can applied into practice safely and efficiently.
