How effective is the non-acid rust removal machine in removing rust from different materials?
The non-acid rust removal machine has different characteristics in rust removal effect on different materials.
1For steel material
Steel is one of the most common application materials. The non-acid-washing rust removal machine has a good effect on removing rust from the surface of steel. It uses physical or chemical non-acid-washing methods, such as mechanical grinding, shot blasting, high-pressure water jet and other principles. Mechanical grinding can accurately remove the rust layer. For thicker rust accumulation, shot blasting can allow steel balls to hit the rust at high speed to cause it to peel off, and it can also form a certain degree of roughness on the steel surface, which is beneficial to subsequent coating and other processes. High-pressure water jet rust removal can penetrate deep into the rust gaps and wash away the rust. It will not corrode the steel matrix like pickling, and can effectively clean the steel surface and restore its original metallic luster.
2For aluminum alloy
The chemical properties of aluminum alloys are relatively active, but the rust on their surface is mainly an oxide film. The methods used by non-acid cleaning rust removal machines, such as micro-abrasive jetting, can gently remove the oxide layer on the surface of aluminum alloys while avoiding damage to the aluminum alloy matrix. Some non-acid cleaning rust removal equipment based on electrochemical principles can accurately control the rust removal process to prevent excessive corrosion or other chemical reactions of the aluminum alloy during the rust removal process, thereby ensuring that the material properties of the aluminum alloy are not damaged, making the surface of the aluminum alloy after rust removal smooth and flat, achieving an ideal rust removal effect.
3. For copper and copper alloy materials
Copper will form rust such as verdigris in the air. The non-acid washing rust removal machine can use ultrasonic cleaning with a suitable rust remover to remove the verdigris. The cavitation effect of ultrasound can make the rust remover react with the rust better and decompose the verdigris. At the same time, through electrolysis and other methods, in a suitable electrolyte, with copper as the anode, by controlling parameters such as current density, the verdigris is dissolved without damaging the copper matrix, ensuring that the surface of the copper and copper alloy after rust removal can restore its original color and texture.
However, the technical parameters and working methods of acid-free rust removal machines of different brands and models may vary, and the actual rust removal effect may also vary depending on factors such as equipment performance, severity of rust, and specific composition of the material.
