Sand Function and Ap
  In the stone abrasive polishing technology, dispersed abrasive polishing is one of the commonly used polishing technologies. In the polishing process, white corundum segment sand is one of the indispensable abrasive products. So, let's learn about the role and application of white corundum segment sand!  White corundum segment sand takes diamond micro powder, silicon carbide micro powder, white corundum micro powder, etc. as dispersion abrasive, mixes with liquid or ointment, uses grinding suspension or grinding paste as abrasive, and adds it to the grinding wheel or workpiece with appropriate device for grinding. This technology is a kind of dispersed abrasive grinding technology.  Different abrasives must be matched with grinding wheels of different materials. For example, tin plated grinding wheel is used when diamond abrasive is used, and gray cast iron grinding wheel is used when silicon carbide abrasive is used. However, because the abrasive is added to the workpiece manually or by a measuring device, the abrasive distribution is uneven, and it requires skilled technicians to achieve high quality standards.  The white corundum segment sand adopts the grinding head technology, with uniform abrasive distribution, good grinding quality, stable quality, easy to realize continuous operation, and high grinding efficiency. Generally, the grinding time is 30%less than that of bulk diamond abrasive. The polishing grinding head technology uses diamond, silicon carbide or white corundum micro powder as abrasive and bond, and uses bonding abrasive to make grinding block by sintering, electroplating or bonding technology. Fix it on the grinding plate to make grinding head. The grinding block is generally bonded with asphalt, sulfur and other materials, and the big white corundum grinding block is connected with the grinding plate through the dovetail groove.  The indispensable materials in our industry are white corundum and white corundum segment sand. It seems that their names are the same. White corundum and white corundum sand have completely different functions. Even the application industry is different. This time, let's talk about the different functions of white corundum and white corundum sand.  It is well known that white corundum segment sand is made of aluminum oxide powder. Therefore, the performance is also very much, and the role is also very much. Let's start with the abrasive. The white corundum segment sand has high purity, high hardness and strong wear resistance. It has a very good abrasive effect and can be used as fine abrasives such as stainless steel, which is much better than other abrasives.  In addition, the white corundum section sand is acid resistant, corrosion resistant and has excellent toughness. As long as the adhesive is added, it is also very good for making grinding wheels. In addition, white corundum crystal is very good and will not occur differentiation, fracture, initiation, etc. , so it is a very good choice as a refractory. These are the functions of white corundum.  On the other hand, from the perspective of the role of corundum segment sand, we generally use it when rough refining steel. The corundum segment sand has high temperature strength, good fire resistance and corrosion resistance, and plays a very important role in refractories. In addition, the white corundum section sand has strong slag resistance and can be used in kilns, so the effect of manufacturing products is also very good. These are the action points of white corundum and white corundum segment sand. To sum up, white corundum and white corundum segment sand have different functions and different effects.
Difference between b
  Brown corundum,also known as emery,is reduced in a high temperature electric furnace.The main raw material is bauxite,and then other auxiliary materials such as anthracite and iron filings are added.The main component of the finished brown corundum is aluminum oxide,with the content ranging from 75%to 95%.In addition,it contains a small amount of other components,namely Fe,Si,Ti,etc.  About the physical properties of brown corundum,its density is mainly introduced.Generally speaking,we know one density,but brown corundum has two:one is the bulk density,and the other is the bulk density.So what are these two?What's the difference?  Bulk density of brown corundum:  The stacking density of brown corundum is 1.53~1.99g/cm3.  The bulk density is the mass of the material that is loaded into the container,without excluding anything.Therefore,the bulk density of brown corundum is related to many factors,such as the particle size,particle size composition,variety,particle shape,etc.Generally speaking,the bulk density of coarse abrasive is greater than that of fine abrasive,and the bulk density of mixed abrasive is greater than that of single abrasive.  Grain density of brown corundum:  The particle density of brown corundum is 3.95~4.0g/cm3.  The particle density is also called true density,which is generally understood as the density,that is,the mass of material per unit volume in a dense state(i.e.,the volume excluding pores).At this time,the finer the abrasive particle size,the more accurate the measured particle density.
Scope of use of brow
  Brown corundum is called industrial tooth:it is mainly used in refractory,grinding wheel and sand blasting.  1.Used for making refractory materials,castables,refractory bricks,etc.  2.Sand blasting-the abrasive has moderate hardness,high bulk density,no free silicon dioxide,high specific gravity and good toughness.It is an ideal"environment-friendly"sand blasting material,widely used in aluminum profiles,copper profile glass,precision molds for washing jeans and other fields;  3.Free grinding-grinding grade abrasive,which is widely used in the field of free grinding of picture tubes,optical glass,monocrystalline silicon,lenses,clock glass,crystal glass,jade,etc;  4.Resin abrasive tools-the abrasive materials have proper color,good hardness,toughness,suitable particle section type and blade retention,which are ideal for resin abrasive tools;  5.Coated abrasives-abrasives are raw materials for sandpaper,gauze and other manufacturers;  Brown corundum segment sand  Brown corundum segment sand  6.Functional filler-mainly used for automobile brake parts,special tires,special building products,etc.It can be used as wear-resistant materials for building expressway pavement,airplane runway,wharf,parking lot,industrial floor,sports ground,etc;  7.Filter medium is a new application field of abrasives.Granular abrasives are used as the bottom medium of the filter bed to purify drinking water or wastewater.It is a new type of water filter material at home and abroad,especially suitable for nonferrous metal beneficiation:petroleum drilling mud weighting agent:  8.Hydraulic cutting is a new,environment-friendly and safe cutting method,which uses abrasive as cutting medium and relies on high-pressure water jet for basic cutting.It is applied to the cutting of oil(natural gas)pipelines,steel and other parts.
