Four rust removal methods for H-beam

We all know that iron things are easy to rust. If we do not properly maintain the Sichuan H-beam, or store it on the wet ground for a long time, it is easy to rust, so how should we remove the rust?

1. Small pneumatic or electric rust removal

This rust removal method is powered by electricity or compressed air, and then equipped with appropriate rust removal equipment to perform back-and-forth movement to meet the rust removal requirements of different occasions, and can roughen the coating to remove rust. The efficiency of rust removal is much higher than that of manual rust removal, and it can be used in many parts, especially in the process of ship repairing.

2. High-pressure water abrasive rust removal

This rust removal method destroys rust and coatings by the impact 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.

3. Shot blasting and rust removal

Shot blasting is to use the rotating impeller to throw the abrasive to the steel surface to achieve the effect of rust removal. This is a relatively advanced treatment method for rust removal of hull steel materials. This method not only has high production efficiency, but also has low cost of use, high degree of automation, and can realize assembly line operation with less pollution.

4. Shot peening and rust removal

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