White corundum powder, white, strong cutting force. Good chemical stability and good insulation. Scope of application: wet or dry jet sand, suitable for ultra precision grinding and polishing in crystal and electronic industries, and making advanced refractory materials.
About the advantages and characteristics of white corundum powder:
1. It does not affect the color of machined parts;
2. It can be used for sand blasting in the process where iron powder residues are strictly prohibited;
3. Micro powder grade is very suitable for wet sand blasting and polishing operations;
4. Fast processing speed and high quality;
5. The extremely low iron oxide content is suitable for sand blasting operations where iron residues are strictly prohibited.
White corundum micro powder polishing has the advantages of fast polishing speed, high smoothness, long service life, no pollution to the environment, and easy removal from the contaminants. Now let’s have a detailed understanding of the application of white corundum powder in the polishing industry, and what is the effect?
1、 Electrolytic polishing: The basic principle of electrolytic polishing is the same as that of chemical polishing, that is, to make the surface smooth by selectively dissolving the small protruding parts on the surface of the material. Compared with chemical polishing, it is better to eliminate the influence of cathodic reaction. The electrochemical polishing process is divided into macro leveling and micro leveling.
2、 Chemical polishing: chemical polishing is to make the material dissolve preferentially in the concave part of the surface micro convex part in the chemical medium, so as to obtain a smooth surface. The main advantage of this method is that it does not need complex equipment, and can polish workpieces with complex shapes. It can also polish many workpieces at the same time, with high efficiency. The core problem of chemical polishing is the preparation of polishing liquid, and the proportion of white corundum sand in the polishing liquid is very important.
3、 Magnetic grinding and polishing: magnetic grinding and polishing is to use magnetic green silicon carbide to form white corundum sand under the action of magnetic field, and the polishing plate is used to grind the workpiece. This method has high processing efficiency, good quality, easy control of processing conditions and good working conditions.
4、 Fluid polishing: Fluid polishing is to achieve the purpose of polishing by scouring the surface of the workpiece with high-speed flowing liquid and white corundum sand particles carried by it.
5、 Mechanical polishing: Mechanical polishing refers to the polishing method to obtain a smooth surface by cutting the plastic deformation of the material surface to remove the convex part after polishing. Generally, oilstone bars, wool wheels, sandpaper, abrasive belts, nylon wheels, etc. are used. The polishing pieces are mainly manually operated. For special parts such as the surface of the rotary body, turntables and other auxiliary tools can be used. For those with high surface quality requirements, ultra precision polishing can be used.
