Silica gel plate: Silica gel plate is an industrial rubber plate made of silica gel as the main raw material. Washers, washers and seals can be punched, mainly used in the fields of food industry, machinery industry, electronic and electrical appliances, automobile industry, chemical light industry, metal and paint. Features of silica gel plate 1. Selectability of thickness. 2. Adjustable color. 3. Simple construction. 4. Stability of quality. 5. Good recoil. 6. Good anti-skid performance.
Tabular Alumina, with the purity, do not add any additives, and firing contraction completely finished sintered alumina, alumina powder as raw material, after fine grinding, molding, drying, for ultra high temperature furnace with the temperature below the melting point of corundum, quick heat cooling fast under the condition of burning, to form a number of closely with columnar crystal, with high purity,high melting point, grains high hardness, heat load of high strength, low shrinkage, high density and low permeability, good wear resistance, good thermal shock stability etc. Tabular Alumina Usage Specification Chemical composition Bulk Density gcm3 Apparent Porosity Al2O3 Na2O Fe2O3 SiO2 Refractory Size 0 1mm 1-3mm 3-5mm 5-8mm 99.0 0.35 0.2 0.2 3.5 5.0 Fine 200 0 325 0 98.5

Function characteristics of white fused alumina sand: It will not affect the color of the workpiece; It can be used for sand blasting in the process of prohibiting iron powder residue; micro powder grade is very suitable for wet sand blasting and polishing; high processing speed and good quality; the content of iron oxide is very low, which is suitable for sand blasting operation in which iron slag is strictly prohibited; Remove impurities by pickling. White corundum abrasive treatment Many advantages of white fused alumina abrasive contribute to its important application in industry, but the waste of white corundum abrasive used in workpiece processing has become the main problem faced by enterprises. When white fused alumina abrasive is used, abrasive precipitation will occur. Of course, there will be other sundries on the workpiece. If the two are combined, the difficulty of cleaning will be further increased.
In the gem world, all kinds of gem-quality corundum other than ruby are called sapphire. The mineral name of sapphire is corundum, which belongs to the corundum group of minerals. In fact, the gem-quality corundum in nature is called sapphire, or colored sapphire, except for red called ruby, and other colors such as blue, light blue, green, yellow, gray, colorless, etc. Sapphire is preceded by a color name, such as pink sapphire. The chemical composition of sapphire (Al2O3) is mainly Fe, Ti, and color. Corundum contains iron (Fe) and titanium (Ti) and other trace elements, and presents blue, sky blue, light blue and other colors, among which the royal blue and cornflower colors that are considered to be thick but not black are the best. In cabochon cutting, when the interior is rich in three groups of inclusions parallel to the bottom surface and oriented, it can produce beautiful six-shot starlight, which is called star sapphire The composition of sapphire is alumina, which is blue due to the trace elements titanium (Ti4) or iron (Fe2). It belongs to the trigonal crystal system, and the crystal form is often cylindrical, short column, plate, etc., and the geometry is mostly granular or dense block. Transparent to translucent, vitreous luster. The refractive index is 1.76-1.77, the birefringence is 0.008, and the dichroism is strong. Heterogeneous body. Sometimes it has a special optical effect - the star effect. The hardness is 9, and the density is 3.95-4.1 g/cm3. No cleavage, fissure development. Industrial sapphire is a material used in special vehicles as transparent armor, and with the exception of diamonds, sapphire is harder than any other natural material. Sapphire belongs to the trigonal crystal system and has a hexagonal structure. The lattice constants are: a=b=4.758A, c=12.991A Refractive index 1.762-1.770 Birefringence: 0.008- 0.010 Uniaxial crystal negative light, in some cases abnormal biaxial crystal light Luster: bright glass luster to adamantine luster Pleochroism: Colored sapphires have dichroism, generally, dark blue/blue, blue/light blue, blue-green, blue-gray, yellow sapphire has golden/yellow, orange/light yellow, light yellow/ Colorless, wait.
