However, white corundum is usually rich in some impurities. The higher the purity of white corundum, the less the impurities. The content of impurities directly affects the function of white corundum. The impurities in white corundum are mainly SiO2, TiO2, Fe2O3 and so on. These impurities will affect his refractory function. Some impurities are fusible, and some impurities have a high melting point. However, when they exist together, fusible materials may occur at high temperatures.
It is actually a microscope with loading equipment and eyepiece micrometer. It consists of the main body of the hardness tester, micrometer eyepiece and related accessories. The micrometer eyepiece is used to query the metallographic or microscopic arrangement and determine the inspection site. , Measuring the length of the diagonal, the collection of data, etc .; the host of the hardness tester ends the switching of the eyepiece and the indenter, applies the load at the determined brown corundum inspection site, and ends the movement of the path to find the image point; Anjing and other specimens.
Grinding of gray cast iron, white cast iron, bronze, brass, ore, aggregate, glass, leather, rubber, plastic and heat-sensitive materials. Black silicon carbide abrasive is also suitable for sand blasting, dry grinding, free grinding and cutting and shaping of jewelry, jade, and agate products. Huanhe black silicon carbide abrasive has greatly improved the economic benefits, so it is an economic project for the future development of refractory materials.
