What are the methods of steel structure rust removal, which method is good?

Answer:

3, hand powered derusting, namely: the use of hand-held electric tools or sandpaper, Fengchan and other tools in the surface rust of steel structure; 4, flame cleaning: the flame surface concentration, because of rust and steel of different thermal expansion coefficient and the two separation.
Method: 1, steel rust blasting, namely: the steel shot by high-speed rotation of the polishing head thrown, shot hit on the component surface and achieve intensive derusting purposes; 2, sand blasting, namely: quartz sand, corundum sand, copper ore sand (price difference) with high pressure air jet carrying on the surface of the component to the purpose of steel rust;
Three kinds of rust removal methods are different, the first two kinds of rust thoroughly, the third methods used for small area, no rust removal equipment; fourth methods are used only, that is, there is no equipment, and the requirements are not high.
