In the process of repairing, removing rust, cleaning paint and polishing the surface of details according to technical requirements to prepare for the next coating phase are very important.
Rust removal and surface cleaning methods:
Due to the influence of humidity, temperature, light, etc. over time, the mechanical and electronic equipment and machinery’s surface coatings are oxidized, rusted, and aged, affecting exploitation performance and use. Depending on the degree of damage, mechanical and electronic equipment will be put into the maintenance and repair process.
In the process of repairing, removing rust, cleaning paint and polishing the surface of details according to technical requirements to prepare for the next coating phase are very important. The rust removal and surface cleaning help the paint film adhere better and have a higher anti-corrosion effect.
Currently, there are many methods of cleaning detailed surface rust:
- Clean with the wire brush
- Clean with the hammer
- Flame cleaning
- Sand disc grinding (using grinding discs)
- Clean with the high-pressure water spray
- Wet sandblasting
- Dry sandblasting
- Cleaning by blasting: Similar to the dry sandblasting method, the advantage is the small amount of dust and the ability to recover up to 99% of the reusable balls.
Overview of the shot blasting solution:
This is a commonly used method, and the surface quality is very high. Rust stains and dirt are completely removed, the surface is well roughened, and the adhesion of the paint layer is significantly improved. In addition, there is a small amount of dust, with the ability to reuse up to 99%.
The operating principle of the blasting room system to recover the steel balls: The machine will push the steel grain into the surface of the steel structure product to be rusted, clean the surface, the compressed air will push the steel ball, steel grain with an enormous kinetic energy and friction force act on the surface of the product to remove impurities or layers of rust. Contaminants or rust layers fall to the recovery floor and are recovered by silo, separating steel ball and dust; the steel ball will be kept in the silo for reuse, dirt is separated from the steel ball and pushed to tank storage, and the exhaust gas is passed through the filter.
According to the above operating principle, to ensure the operation of the system, it is necessary to invest in the following equipment:
- Spray room with rubber lining and lights.
- Equipment to recover steel particles and dust.
- Steel grain spray equipment
- Ray, trolley to bring products in and out.
- Air compressor for dust removal- steel grain spray
- Steel beads with appropriate specifications.
