This article will let Baowu take you to know more about it.

We all know that iron things are easy to rust, but if steel products such as H-beams are not well maintained or encounter some harsh environmental problems, rust will also occur.

The rusting of H-beam will affect the service life of the H-beam. Once the rust of the H-beam is not handled in time, the corrosion resistance will be reduced.

Therefore, we need to derust the rusted H-beam. Let's list several methods for derusting.

Small pneumatic or electric rust removal:

Powered by electricity or compressed air, and then equipped with appropriate rust removal equipment, it performs back and forth movement to meet the rust removal requirements of different occasions, and can roughen the coating. The efficiency of rust removal is higher than that of manual rust removal. much higher.

High pressure water abrasive rust removal:

Destroys rust and coatings by the impingement action of high pressure water jets. It is characterized by no dust pollution and no damage to the steel plate, greatly improving the rust removal efficiency and good rust removal quality. But there is a disadvantage that the steel plate after rust removal is easy to rust, and the subsequent problems need to be repaired.

Shot blasting and rust removal:

The abrasive is thrown to the surface of the H-beam by the rotating impeller to achieve the effect of rust removal. This is a relatively advanced treatment method for rust removal of hull steel materials. This method has high production efficiency, high degree of automation, and can realize assembly line operation with less pollution.

Shot peening and rust removal:

The effect of surface cleaning is mainly achieved by particle spraying. It is widely used and can thoroughly remove impurities on the metal surface. It has high rust removal efficiency, high mechanical level and good rust removal quality.

The above are the reasons for the rust of H-beams and how to deal with them. If you want to know more, please pay attention to Baowu at any time.
