Study On Surface Rust Removal And Corrosion Prevention Of Color Steel Tile

With the advent of the era of science and technology,steel both in the industrial production and daily life plays a vital role.According to statistics,every year there are tens of millions of tons of steel in the world became rust due to not properly and protect,iron and steel products due to corrosion damage caused by slashing production,product quality,environmental pollution,harm to human health,and even cause serious accident with the loss is incalculable.As a result,steel rust not only has an important economic significance but also has an important social significance.The color steel is currently the most widely used building materials,with its advantages of beautiful appearance,light weight,low price is widely used in plant construction,temporary accommodation and other aspects,especially the strong earthquake resistance,waterproof,etc.has been widely promoted.However,the color steel tile also has its Achilles heel.The paper by reading a lot of literature,the mainstream of traditional anti-rust method at home and abroad are reviewed.Comparing the advantages and disadvantages of various the methods rust protection,combining with the actual industrial production line and the extent of the antirust effect,finally determine the two kinds of rust route: ethanol amine and acid compound with rust,phosphating film rust.These two kinds of rust prevention method has simple process,low equipment investment cost effective,rust,etc,is a highly efficient,economic and environmental anticorrosive methods.Broke the traditional antirust method is expensive and inefficient,pollution caused by the spell.Then through the orthogonal experiment selected three kinds of rust inhibitor formula of optimal ratio.Next conducted a series of characterization of the experiment.Antirust effect through the characterization of experiment data analysis to be the best,the most economical and most the best anti-rust agent formula is suitable for industrialized production.At the same time,the corrosion mechanism of steel surface is deeply studied and analyzed,and the specific corrosion reasons and corresponding protection solutions are analyzed in different environments.
