In the air, oxygen accounts for 21%, and rusting is a change after oxidation caused by the oxygen in the metal and the air. Rusting is a chemical reaction that is essentially the oxidation of metals. Therefore, it is very common for all kinds of metals to rust. As large as aircraft carriers, aircraft, ships, and as small as embroidery needles, they will be damaged by oxidation and rust. Now, there is no way to prevent them, but better The best way to relieve rust or directly remove rust!
There are three main methods of rust removal: chemical rust removal, manual rust removal, and mechanical rust removal
①、chemical rust removal:
Chemical rust removal is a method that uses chemical reaction to dissolve general rust, oxide scale and various corrosion products from the surface of the workpiece without affecting the base metal. Inorganic acids and organic acids are commonly used as rust removal materials, so they are often called pickling. This method has a fast rust removal effect, but it is not conducive to environmental protection and has a great impact on the environment. At the same time, chemical rust removal also makes the product react with chemicals. be processed.
②、Manual rust removal:
Manual rust removal is aimed at a single workpiece and has very low power. It is generally suitable for small areas and places where sandblasting is not required.
③、Mechanical rust removal:
Mechanical rust removal should be the best method in the rust removal process. It is flexible to use, there are many methods, and the effect is good and the power is high!
Mechanical rust removal is a physical rust removal method, which not only greatly reduces the cost, but also reduces labor. Surface hardness, life and adhesion, sand blasting is the most common type of mechanical derusting.
Sand blasting and rust removal is the most thorough, fastest and most effective method in the rust removal process; Sand blasting can choose between different roughness, smooth and rough, other mechanical rust removal can not achieve this kind of power and effect. When it comes to sandblasting and rust removal, it is inevitable to involve sandblasting and rust removal machinery - sandblasting machine, sandblasting machine Through the continuous opening and innovation of people, there are more and more types of products, more and more scope of use, and more and more refined processing operations, and even models such as automatic and intelligent unmanned operation are presented, even from sandblasting machines. Many new products have been reproduced, such as: shot blasting machine, burr machine, sandblasting room and so on!
