Cheap Black Synthetic Corundum Manufacturers

Black corundum is closely related to life, polishing products around it, stainless steel, aluminum products. And commonly used bicycle, sewing machine, motorcycle and watch parts. It's trivial widgets, but not without them. Black corundum can also process materials, manufacture abrasive discs and tools, resin cutting discs, and so on. There is another new use of aluminium oxide grit suppliers. The pedestrian bridge is used to test black corundum for non-slip.

Winter roads are prone to water and skid on rainy and snowy days, brown fused alumina price which in turn can corrode the steel plates of bridges and have poor skid resistance in freezing weather. Newly constructed bridges no longer use rubber sheet to pave the deck, and at the same time boldly use the new material white aluminum oxide blast media for bridge deck reconstruction. This will make the product quality unstable and easily cause defects such as deformation, foaming, black core, unstable hardness or low strength. 


Practice has proved that the application of white alumina is waterproof, wear-resistant and non-slip. At high temperatures, the binder begins to shrink due to the melting of the low-melting material, and the porosity begins to decrease. The temperature at this time is called the sintering temperature. Rhenium continues to heat up, shrinks to a large value, and the aluminium oxide blasting porosity decreases to a low value. The temperature at this time is called the complete sintering temperature.


The temperature continues to rise, and the green body begins to soften or begin to expand. A- to local melting. The brown aluminum oxide temperature at this time is called the softening temperature. The temperature range from complete sintering to the beginning of softening is called the sintering range. The white aluminum oxide abrasive 220 grit sintering temperature and the complete sintering temperature can be determined by measuring the changes in volume shrinkage and water absorption.


It can also be measured using a high Ju microscope. The pink corundum starting softening temperature is measured by a Sichuan high temperature microscope. Because the procedure of accurately determining the above-mentioned meaning of the burnout is difficult, and a high microscope is required. Therefore, a simplified method is sometimes used. That is, the white fused aluminum oxide temperature at which the water absorption of the sample is 6% and 2% is used as the sintering range.


The brown fused alumina sintering bonding agent is already in the molten state under the sintering overflow degree. Therefore, sintering Fan Shan is only used as the sintering range. Normative reference data. However, for sintered binders, the sintering range is a more important parameter. For sintered binders that are too narrow, the black aluminum oxide 70 grit abrasive media product often overburns or is partially burned due to fluctuations in overflow or temperature differences in the kiln.


The two test methods that need to be proposed here are commercial microscope tests. The aluminum oxide grit high temperature microscope test is a comprehensive test, which can observe and take pictures of the entire process of the sample from heating to melting. From the temperature of each point of the sample's expansion, shrinking, shrinking, melting to full melting, it can be inferred that the sample's approximate sintering range, fire resistance, and 220 grit aluminum oxide blast media temperature range starting to melt to full melting.
