cheap brown aluminum oxide manufacturer in china
by Terry Ma ManagerAdding brown corundum to the refractory can make its performance more stable and improve its performance at the same time. Sandblasting is mainly used in copper, aluminum, glass, ceramics, jeans and other related fields, while white corundum is used for free grinding in: various lenses, glass, jade and other related products. brown fused aluminum oxide is also effective in filtering water quality, which is applicable to: purification of drinking water, wastewater treatment, targeted application to non-ferrous metal beneficiation and oil drilling, etc.
The amount of wear can be indicated by the mass, volume or thickness of the ground brown corundum and white corundum. The method of weighing is used to determine the amount of wear, that is, to weigh the mass change of the sample before and after the experiment. The precision analytical balance is usually used for weighing, with the measurement accuracy of 0.1mg. During the experiment, in order to ensure the weighing accuracy, it is necessary to clean and dry the (brown) white corundum sample before weighing, so as to prevent the weight from being affected by dirt on the surface.
The main difference between shale shaker and shale shaker is that the motion direction of shale shaker is basically parallel to the screen surface, and the vibration direction of shale shaker frame is vertical or nearly vertical to the screen. Because of its simple structure, shale shaker is widely used in black corundum abrasive plants, but it is not an ideal classification equipment due to its large noise, large floor area and low screening efficiency. Probability screen is also an inertial vibration Moving screen, but its working mechanism is essentially different from other vibrating screens.
First of all, the white corundum sand can replace the staggered quartz sand because the anti sticking effect of the staggered quartz powder coating is better, and the high-temperature performance of the staggered quartz powder is very good. Compared with the high-temperature performance of the white corundum powder, the high-temperature performance of the white corundum powder is not as good as that of the white corundum powder, making the white corundum powder coating easy to produce problems such as the sand sticking weight of the casting surface.
In winter, the road surface is prone to waterlogging and slipping in rainy and snowy days, which corrodes the bridge steel plate, and the anti-skid performance is poor in freezing weather. The new bridge no longer uses the rubber plate to pave the bridge deck, but boldly uses the new material pink corundum in the bridge deck reconstruction. Practice has proved that the application of black corundum is waterproof, wear-resistant and antiskid. At high temperature, the volume of the binder begins to shrink and the porosity begins to decrease due to the melting of the low melt.
In a word, the phase, microhardness and microdefects of bond in abrasives should be analyzed in combination with the use of abrasives and the main requirements of abrasives, and other physical and chemical properties of bond, so as to get a comprehensive concept, which can be used as the basis for choosing bond. Both white corundum and brown corundum contain alumina, and the hardness of white corundum is slightly higher than that of brown corundum, and white corundum alumina contains alumina The content is more than 99%, and the alumina content of brown corundum is more than 95%.
