Studying The Effect of Low Temperature on Adhesion Strength of Internal Lining Coating for Steel Liquid Gas Storage Tanks

Abstract

Metal storage tanks for liquid gas are unstable at low temperature (below zero degree centigrade), because the metal tends to be brittle and susceptible to crack. In this research studying some physical properties such as shrinkage, adhesion force and coating layer thickness of aluminum powder with ethyl silicate as a binder were performed. The results shown, that the coating with such layer has excellent resistance to low temperature and impermeable to liquid gas for example, propane, methane and nitrogen a suitable coating layer thickness is (5mm). The data and results were optimized by using Taguchi / ANOVA Technique.
