How to solve the rust of H-shaped steel?

How to clean the rust of H-shaped steel when in use, the solution of H-shaped steel rust,

The rust of H-shaped steel seriously affects the service life of Xinjiang H-shaped steel, once the rust of H-shaped steel is not treated in time, it will cause the reduction of corrosion resistance, the more severe the show, and finally lead to alkali break, reducing the service life, so once the H-shaped steel rusts, it should be cleaned up in time, the following is the method of processing the rust of H-shaped steel provided by Zhongao Huixin H-shaped steel sales to you, so that the rust of H-shaped steel is removed thoroughly.

1. Cleaning

The use of solvents and emulsions to clean the surface of steel to remove oil, grease, dust, lubricants and similar organic matter, but it can not remove rust, oxide, welding, etc., on the surface of steel, so it is only used as an auxiliary means in anti-corrosion production.

2. tool rust removal H-shaped steel

Mainly use wire brush and other tools to polish the steel surface, which can remove loose or warped oxide, rust, welding slag and so on. The rust removal of hand tools can reach Sa2 level, and the rust removal of power tools can reach Sa3 level. If the steel surface is firmly attached to the oxide scale, the rust removal effect of the tool is not ideal, and the anchor grain depth required for anti-corrosion construction is not reached

3. Pickling

Generally, chemical and electrolytic methods are used for pickling treatment, and chemical pickling is only used for pipeline anti-corrosion, which can remove the oxide, rust, and old coating, and sometimes can be used as reprocessing after sandblasting. Although chemical cleaning can make the surface reach a certain degree of cleanliness and roughness, its anchor pattern is shallow, and it is easy to pollute the environment.

4, spray (throwing) jet rust removal

Spraying (throwing) jet rust removal is driven by a high-power motor to spray (throwing) jet blade high-speed rotation, so that steel sand, steel balls, iron wire segments, minerals and other abrades under the action of centrifugal force on the surface of Xinjiang steel pipe spraying (throwing) treatment, not only can completely remove rust, oxides and dirt, but also the steel pipe in the abrasive impact and friction force under the action of It can also achieve the required uniform roughness, so that the H-shaped steel will not rust easily
