Brown corundum abrasive is one of the artificial corundum materials, brown in color, with high purity, high fluidity, low coefficient of linear expansion, corrosion resistance, so what is the use of brown corundum abrasive?
Brown corundum is made of high quality bauxite, iron filings, anthracite coal smelted at high temperature in electric arc, crushed and shaped by self-mill, magnetic separation to remove iron, sieved into various size models.
Brown corundum abrasive uses:
1, used in the manufacture of advanced refractory materials, pouring materials, refractory bricks, etc.
2, sandblasting - abrasive hardness moderate, high bulk density, no free silica, specific gravity, good toughness, is the ideal "environmental protection" sandblasting materials, widely used in aluminum profiles, copper profiles glass, washed denim precision mold and other fields.
3, free grinding - grinding grade abrasives, used in the field of video tubes, optical glass, single crystal silicon, lenses, watches and clocks with glass, crystal glass, jade and other areas of free grinding, is commonly used in the domestic advanced grinding materials.
4, resin abrasives - abrasives with suitable color, good hardness, toughness, suitable particle section type and edge retention, applied to resin abrasives, the effect is ideal.
5, coated abrasives - abrasives are the raw materials for the production of sandpaper, gauze and other manufacturers.
6, hydraulic cutting - is the abrasive as the cutting medium, relying on high-pressure hydraulic jets for basic cutting, applied to oil (natural gas) pipelines, steel and other parts of the cutting, is a new, environmentally friendly, safe cutting method.
Brown corundum abrasive is brown in color, it is one of the artificial corundum materials, which has the advantages of dense texture, high hardness and toughness, etc. What are the characteristics of brown corundum abrasive?
The characteristics of brown corundum abrasives:
1, the outstanding feature is the small size of the crystal impact resistance, because of the processing of crushing with impact crusher, the particles are mostly spherical particles, the surface is dry and clean, easy to bonding agent bonding.
2, brown corundum abrasive grinding ability, good wear resistance, high durability, easy to control the processing size, to achieve processing automation.
3, Brown corundum abrasive has high grinding efficiency. When processing carbide and non-metallic hard and brittle materials, the metal removal rate of diamond grinding wheels is better than that of cubic boron nitride grinding wheels.
4, Brown corundum abrasive processing cost is low. Diamond grinding wheels and cubic boron nitride grinding wheels are relatively expensive, but the total cost is low due to their long life and high processing efficiency.
5、Low grinding force, low grinding temperature, good surface quality, no burns, cracks and tissue changes. When diamond grinding wheels grind carbide, the grinding force of brown corundum abrasive is only one quarter to one fifth of that of green silicon carbide grinding wheels.
Brown corundum micronized powder has high purity, good crystallization, strong fluidity, low linear expansion coefficient, corrosion resistance, and has the characteristics of no explosion, no pulverization and no cracking in the application process. So what are the uses of brown corundum micronized powder?
Brown corundum micronized powder uses:
1, precision casting: stainless steel, aluminum castings and other fusion mold, silica sol process in the layer, the middle layer, the surface layer, etc.
2, functional filler: mainly used for automotive brake parts, special tires, special construction products, etc. Collar can be used as the construction of highway pavement, aircraft runways, docks, parking lots, industrial flooring, sports venues and other wear-resistant materials.
3, sandblasting: widely used in aluminum profiles, copper profiles glass, washed denim molds and other fields, mainly for the decontamination of various materials workpiece, rust removal, anti-corrosion, remove oxidation skin, light decoration, effect patterns, etc.
4、Abrasives: can be made into ceramic grinding wheels, resin grinding wheels, grinding heads, modules, sandpaper, sand belts, gauze and polishing wax, abrasives, abrasive paste, coatings, etc.
5、It is used for brown corundum micronized refractory materials, casting materials, refractory bricks, gun clay, etc.
6、Hydrodynamic cutting: It is to use brown corundum micronized abrasive as cutting medium, relying on high pressure hydraulic jet for basic cutting, applied to oil (natural gas) pipeline, steel and other parts of the cutting, is a kind of assured and reliable cutting method.
7、Filtration medium: It is another application field of abrasive, using granular abrasive as the bottom medium of filter bed to purify drinking water or wastewater, it is assured water filtration material, especially suitable for non-ferrous metal beneficiation: oil drilling mud aggravating agent.
What is brown corundum abrasive suitable for grinding? Brown corundum is a kind of artificial corundum abrasive, which is widely used because of its relatively cheap price and strong grinding power. So do you know what brown corundum abrasives are suitable for grinding?
Brown corundum is made of high quality bauxite, iron filings, anthracite coal smelted at high temperature in electric arc, crushed and shaped by self-mill, magnetic separation to remove iron, sieved into various particle sizes, the particle size of brown corundum abrasives produced by our factory is produced according to international standards and national standards, and can be processed according to the particle size required by users."

Brown corundum is suitable for grinding what: 1:
1. coated abrasives, brown corundum abrasives not only in the performance of the advantages also occupy an advantageous position in the cost, in the choice of material its performance can not only be comparable with other abrasives can also reduce the production cost of abrasives.
2. Grinding and polishing materials, brown corundum abrasives in the field of grinding and polishing more and more applications, such as polishing stainless steel, glass, bamboo and other workpieces, grinding and polishing of metal parts, non-metallic surface treatment processing, etc. have good applications.
3. making resin abrasives, ceramic abrasives, etc., using the performance characteristics of brown corundum, brown corundum particle size sand in the production of resin abrasives and other abrasive fields to become the main application materials, can improve the sharpness of the grinding wheel and the use of periodicity, and low cost is conducive to the improvement of production efficiency.
1、Protect the parts on the brown corundum that are not allowed to be blasted on sand as required.
2、Put into the blasting chamber, in the process of blasting, will not collide with each other and obstruct.
3、Close the door of the shot blasting machine. Brown corundum start shot blasting work, the door of the blasting machine must be closed to avoid sand and dust pollution shot blasting environment.
4, shot blasting steel bead size of 1 ~ 1.5mm.
6, sandblasting brown corundum construction should also check the shot blasting workpiece, if there is not sprayed or shot bad parts, the workpiece re-spray.
5, sandblasting, gun nozzle and workpiece spacing to maintain at about 10 ~ 20cm, vertical uniform movement, while rotating the workpiece in hand, so that the abrasive surface evenly sprayed shot.
Brown corundum in the process of using many details are related to the later use of the effect, and in the application of the time we should also do some protection. Such abrasives in the process of use, especially to the sandblasting link, must pay attention to these matters.
Corundum and high alumina self-flowing refractory castable water dosage is 6.0%~6.8%, slightly higher than the same material vibration low cement refractory castable, 1500 ℃ after burning line change is basically similar, strength is slightly lower still better.
