Wettability Test Of Oil-water Medium On Varied Coating Surface And Antiscaling Paint Optimization

This paper main research fields in a variety of coating surface oil and water mediumwettability of can, the purpose is to find a low wettability of coating material, this paint cangreatly reduce the oil and water medium and the equipment surface touch each other degreethat the oil and water medium not easy in metal component surface scaled. This inhibitioncoating can be used in the production process of mechanical equipment, thereby reducing theoil production process by material and scaling in losses.Paper by a large number of trial to measure in a variety of coating surface oil and watermedium the contact Angle and roll Angle of size, experimental materials including nano sandhigh temperature coating,118coating,618coating,20carbon steel substrate,304stainlesssteel substrate, phenolic coating1,2, epoxy coating phenolic coating, epoxy coating2,1epoxy coating3, through the data analysis research, sewage, water, oil and water three yuanfluid and crude oil recovery liquid medium in material surface wettability of.Through to the oil and water, sewage, water, three yuan liquid and crude in liquid mediumof coating surface contact Angle and rolling Angle measurement and comparison, thecomprehensive evaluation of the material surface wettability can. Among them, the differentliquid medium in the same solid materials on the surface of the contact Angle performanceand rolling Angle have remained; The same liquid medium in different solid material surfacecontact Angle has the very obvious differences, and rolling Angle but no obvious difference.All kinds of coating is heavy, and the sand nano coating the contact Angle and hightemperature rolling Angle are obviously better than the other materials, and finally confirmedthe wettability, has the lotus leaf can lower the effect and scale coating-nanometer sand hightemperature coatings.In view of the heating furnace tube type oil fire fire scaling problems tube is very serious,will come out of the sand add optimization nanometer high temperature in the furnace pipecoating on fire and scale coating construction, and then has engaged in a year of the actualworking condition, the experimental results show that the fire tube surface coating and scaleeffect is obvious, reheating furnace thermal efficiency is increased8%, and can effectivelyavoid the risk of burning heat tube.
