Steel bars are an important raw material for the construction industry. Building construction requires steel bars to be straight, free from damage and cracks, and free from oil stains and rust. However, since rebar is often exposed to outdoor environments, corrosion is a common occurrence. This requires that after the steel bar is corroded, it must be dealt with in time, otherwise it will cause safety hazards.
Corroded steel bars cannot be used in construction, so how to ensure that steel bars are not corroded? How to remove rust?
According to the steel bar rust removal specification, it can be divided into the following five categories according to the degree of corrosion of steel bars:
There is oxidation and corrosion on the surface of building steel bars;
A steel surface that is fully covered with scale and almost free of rust;
The steel surface where rust has occurred and part of the oxide scale has been peeled off;
Scale has peeled off due to rust, or can be scraped off, and there is a small amount of pitting on the steel surface;
The steel surface where the oxide scale has been completely peeled off due to rust, and pitting corrosion has generally occurred;
The laser beam emitted by the laser cleaning machine is absorbed by the contamination layer on the surface of the material to be treated;
The absorption of large energy forms a rapidly expanding plasma (highly ionized unstable gas), which generates a shock wave;
The shock wave shatters the rust and removes it;
The hand-held laser cleaning machine produced by ACCTEK factory is an ideal rust removal equipment for steel bar rust removal, and it is very effective for steel bar rust cleaning. The rust-removed steel can continue to be used in the construction industry without worrying about safety.
