Aluminium Oxide Blast Media

The current industry's primary use of aluminium oxide blast media includes first-class brown corundum grain sand, brown corundum polishing sand, aluminium oxide blast media for metal rust removal, brown corundum sand for denim, brown aluminum oxide sand for hot drilling and rhinestones. Due to its brittle nature, the slag is easily broken to form tiny particles of dust during the sandblasting and abrasive process. Aluminium oxide blast media is used for surface spray grinding treatment.

Therefore, judging from the specific value of corundum abrasive, the bulk density of aluminium oxide blast media is relatively low, ball frosting is medium, and the bulk density of barmac sand is relatively high. If there are special requirements and the need for shaping sand, the aluminium oxide blast media bulk density is relatively low. Moreover, the usefulness of each manufacturer is quite different. Aluminium oxide blast media used for polishing is exquisite.

The less the aluminium oxide blast media, the better the matt effect. White corundum is usually used as a blasting medium. Aluminum oxide blast media is the most ideal product for grinding, polishing and sandblasting stainless steel products. In the process of machining parts, if you do not want to have iron powder residue, white corundum is the best aluminium oxide blast media. The most important thing is that aluminium oxide blast media is the lowest cost of all surface treatments.


Aluminium oxide blast media is mainly used by an automatic sandblasting machine to use compressed air to flow in the nozzle at high speed to form a negative pressure to produce an ejection effect. The aluminium oxide blast media is sucked into the nozzle through the sand pipe, and then it is jetted to the workpiece from the nozzle at a high speed with the compressed air flow. Surface, to achieve the purpose of sandblasting.

In the working state, compressed air and aluminium oxide blast media are mixed while spraying, so that the compressed air can be fully utilized. The air flow rate and the aluminium oxide blast media flow rate are easy to adjust, and the ideal mixing ratio, energy and aluminium oxide blast media can be obtained. Because of its high specific gravity, there is less dust generated during the aluminium oxide abrasive spraying process.


Due to the performance advantages of aluminium oxide blast media, such as high hardness, good toughness, high specific gravity, and no harmful substances, it has played an important role in the international blast cleaning industry. It is required that aluminium oxide blast media is made of almandine, because almandine contains different main end-member molecules. The aluminum oxide sandblast media composition meets the industry's requirements for hardness.

Aluminium oxide blast media is very suitable for wet sandblasting, grinding and polishing operations. White corundum is harder than brown corundum. It is brittle, not only has strong cutting force, but also has good chemical stability. The amount of iron oxide contained in aluminium oxide blast media is very low, which is suitable for alumina blasting operations where iron residues are strictly prohibited.


Aluminium oxide blast media is the most suitable product among sandblasting abrasives. In contrast, other sandblasting effects are far less effective than aluminium oxide blast media. The reason is that the glass structure formed by other sandblasting in cold water is fragile. The dust will cause harm to the human body and the environment. The bulk density of various types of aluminium oxide blast media products are quite different.

Aluminium oxide blast media is manufactured by fused high-quality bauxite ore. Brown corundum sandblasting is prepared with cooked bauxite, iron filings, and coke in a certain proportion. The outstanding features of aluminium oxide blast media include the level of content, Brown fused alumina has the most complete effect, the strongest adaptability, and the widest application range among various surface and interior pretreatment methods.


At present, the white corundum used as a grinding medium accounts for 45% of all industrial consumption. Aluminium oxide blast media can be used to control the internal and external disturbances of some special objects, and the cost of sandblasting grit is the lowest. Polishing craftsmanship is more precise, but efficiency is more important for aluminium oxide blast media machines.

After aluminum oxide powder sandblasting, the surface is white without any impurities, eliminating the trouble of cleaning. The secondary and secondary white aluminum oxide blast media are mainly used for the polishing and grinding of workpieces, the production of grinding wheels, and the sandblasting of large workpieces. The role of aluminium oxide blast media for sandblasting is to adjust toughness, moderate hardness and high aggregation density.


When sand blasting in closed equipment, aluminium oxide blast media operators must wear sand clothes, install exhaust (exhaust) equipment, and have a dedicated person in charge of internal and external contact at the hole. Therefore, aluminium oxide blast media improves the fatigue relief of the workpiece, increases the adhesion between it and the coating, extends the durability of the coating, and is also conducive to the leveling and decoration of the coating.

Aluminium oxide blast media is an ideal "environmental friendly" aluminium oxide blast media with moderate hardness, high bulk density, no free silicon dioxide, large specific gravity and good toughness. It is widely used in the fields of aluminum profiles, copper profiles, glass, washed jeans precision mold, etc. Aluminium oxide blast media personnel must wear sand clothes or canvas work clothes, wear dust-proof masks, high-top sneakers, and canvas gloves.


Aluminium oxide blast media uses compressed air as the power to form a high-speed jet beam to spray the aluminium oxide blast media to the surface of the workpiece to be treated at high speed. Aluminium oxide blast media can make the cleaned surface obtain the required cleanliness and roughness at the same time, and abrasive blast media improve the adhesion of the coating on the basic surface. Therefore, the workpiece rust removal is essential.

Aluminium oxide blast media changes the appearance or shape of the outer surface of the workpiece surface The impact and cutting effect of media on the surface of the workpiece make the surface of the workpiece get a certain degree of cleanliness and different roughness, and improve the mechanical properties of the workpiece surface. Brown aluminum oxide blast media is suitable for surface beautification of various high-end products, crafts or hardware.


After the surface of aluminium oxide blast media is coated with industrial coating with good performance, the coating life can be more than 3.5 times higher than the same quality coating on the surface treated by other methods. Aluminium oxide blast media is a kind of sand blasting and derusting abrasive that we often choose.

What should we pay attention to when choosing aluminium oxide blast media for derusting? No matter how good the coating is, it can not adhere to the surface of the workpiece without surface treatment for a long time. Aluminium oxide blast media for sand blasting has moderate hardness, high bulk density, no free silica, heavy specific gravity and good toughness.


Among all kinds of surface treatment methods, aluminium oxide blast media has the most obvious effect, and can adapt to a variety of complex projects. The effect of single choice of aluminium oxide blast media is not obvious. Workpiece rust is often encountered in industrial production, if not, it is likely to cause damage to the workpiece, and if it is serious, the workpiece will be scrapped.

The stability and pressure of aluminum oxide blasting media mechanical equipment, projection distance, sealing, aluminium oxide sandblasting time are important factors affecting sandblasting. The aluminium oxide blast media workpiece has just been sprayed, so someone needs to carry out surface maintenance in time to avoid re contamination. This is because aluminium oxide blast media is the fastest and most thorough to clean the steel surface. 


Another advantage of aluminium oxide blast media is that the surface roughness can be determined in advance according to the requirements and can be easily achieved in the cleaning process. After the coating of aluminium oxide blast media, the coating cycle is 3.5 times higher than that of the same quality coating. Another feature of aluminium oxide blast media is that the surface roughness can be determined according to the requirements in advance.

The control personnel of aluminium oxide blast media should wear work clothes, work caps, dust masks and goggles The lighting equipment used by media must be a 36V safety light with a protective cover. Do not sandblast in foggy, rainy or dewy weather, because aluminium oxide blast media needs temperature and humidity up to standard during rust removal. Aluminium oxide blast media finish the painting work within 4 hours.


Only aluminium oxide blast media can be evaluated by four cleaning grades that have been formulated and accepted by all; Aluminum oxide blast media can not only deal with complex surfaces that are difficult to clean, but also clean the pipe surface with tools. The main machines used in aluminium oxide blast media are manual sand blasting machine, automatic brown aluminum oxide sandblasting machine, vibration grinding machine, etc.
