What is the rust removal method for stainless steel handle? With the increasing popularity of stainless steel handles, many problems of stainless steel handles have also been criticized one by one, the most serious of which is the rust removal method of stainless steel handles.
1. Manual derusting
Manual derusting is the original derusting method, with poor labor protection. Generally, rust remains on the cleaned metal surface, and the quality is unstable. However, this derusting method is simple and adaptable, and is still a common derusting method.
2. Jicheng grinding
Mechanical polishing is to remove the rust layer by means of impact and friction with the help of mechanical driving force. Then remove the rust. Common tools include electric grinding wheel, pneumatic brush, electric brush, derusting gun and needle derusting device. Different tools have different advantages and disadvantages. For example, the needle beam deruster is a small pneumatic tool with a needle beam. The needle beam can be adjusted according to different curved surfaces. For curved, narrow, uneven and angular seams, such as oxide skin, rust layer, old coating and welding slag, the needle beam deruster can be used to clean, with good quality, less energy consumption, simple operation and higher efficiency than manual derusting.
3. Derusting of drum
Rust removal of stainless steel handle drum is to place metal workpiece and pig iron castings without abnormal angle and external thread in a slowly rotating hexagonal or circular drum. Due to the rotation of the drum, rust and oxide scale and other dirt can be removed by friction and rolling impact.
4. Flame derusting
Flame derusting is applicable to the derusting of steel structure and casting surface with certain thickness. Its principle is to use the difference of thermal expansion coefficient between metal and oxide skin. After heating, the oxide skin will break and fall off, while the rust layer will break and loose due to the dehydration effect during heating.
5. Electric spark derusting
Electric spark derusting is to remove rust by taking advantage of the different conductivity and thermal expansion rate of oxide scale and steel plate. The cleaned metal workpiece is regarded as an electric ji, and the round roll is regarded as another electric ji. When the round roll contacts with the workpiece, it will produce a short circuit to separate the oxide scale, and the rust will be separated from the surface of the workpiece with the help of mechanical impact force.
