I. Different crafts
1, sandblasting: Sandblastic uses compressed air as the power to form a high -speed jet bundle (copper ore sand, quartz sand, diamond sand, iron sand, sea sand) at high speed sprayed to the required workpiece. On the surface, the appearance or shape of the workpiece surface changes.
2, scrub: The frosted object becomes not smooth, making the light irradiated on the surface to form a sprinkler -like process. For example, the frosted glass makes it opaque, matte leather jackets, making it less bright than the ordinary leather.
. Different effects
1, sandblasting: The abrasive impact and cutting effect on the surface of the workpiece, so that the surface of the workpiece can obtain a certain cleanliness and different roughness, so that the mechanical performance of the surface of the workpiece is improved. Therefore, the anti -fatigue of workpiece is improved, the adhesion between it and the coating, the durability of the coating film is prolonged, and it is also conducive to the flatness and decoration of the paint.
2, frosted: Machine grinding or manually grinding glass with abrasives such as diamond, silicon sand, pomegranate powder and other abrasives to make a uniform and rough surface. The products have become frosted glass and other products. The closed performance is better after scrub processing.
In beauty, skin frosterness is also a common method. It refers to gently massage the skin to remove the skin's keratin with some small granular beauty substances.
. Different uses
1, sandblasting: metallurgy, ink carbide, glass and glass products, enamel, casting steel, water filtration, soaking flower alkali, chemical, sandblast and other industries.
2, frosted: glass, leather, skin, etc.

The difference between the metal surface treatment of sandblasting and frosted
1. The difference in processing process
The sandblasting machine is sprayed with the diamond sand through the blasting machine, and the metal surface is hit. Wait) Make sand surface on the metal surface.
2. The difference between the treatment effect
This is that the objects with smooth surfaces become smooth, and sand spraying makes the surface of the workpiece obtain a certain cleanliness and different roughness.
3. The difference between using the operating equipment
The frosted machine, sandblast machine, sandblasting machine and liquid sandblasting machine.
The sandblast effect is as follows:
This effects as follows:

The sandblast operation rules
1. You must wear protective supplies before work, no Quickly work naked. There are no less than two people at work.
2, gas storage tank, pressure gauge, safety valve should be checked regularly. The gas storage tank is discharged every two weeks of dust, and the filter in the sand can is checked once a month.
3, check whether the ventilation pipe and the sandbase door are sealed. Five minutes before work, a ventilated dust removal equipment must be started. When the ventilation and dust removal equipment fails, the sandblast machine is prohibited.
4, the compressed air valve should be opened slowly, and the air pressure should not exceed 0.8MPa.
5, the particle size of the sandblast should be compatible with the requirements of the work. Generally, it is applicable between the ten to 20th and the sand should be kept dry.
6. When working on a sandblast machine, it is forbidden to approach the unrelated personnel. When cleaning and adjusting the operating site, it should be stopped.
7, not allowed to blow dust or joke with compressed air.
8. After the work is completed, the ventilation and dust removal equipment should continue to run for five minutes before turning off to discharge indoor dust and keep the venue clean.

The metal surface scrub picture:
metal surface sand spray pictures:
extension information:
Thasis is through mechanical methods (grinding, sand spraying, spray spray, etc.), etc. Chemical or electrochemical methods make metal surface sand surface. The surface of matte treatment is not reflective, soft, and can also increase the binding force of the coating layer.
S sand treatment is the most thorough, most common, fastest, and efficient cleaning method. Sandblastic treatment can be arbitrarily selected between different roughness, and other processes cannot achieve this.
This grinding can hit the hair but the speed is too slow. The cleaning of the chemical solvent is too smooth and the coating is not conducive to the coating bonding.

The surface treatment of the metal is bumpy with the surface of the sand spraying machine, which increases the adhesion, which is conducive to the subsequent spraying process.
The scrub is just polishing the surface rust. The surface of the workpiece is smooth. If the paint is painted, the paint is easy to paint, and the effect is not particularly good.
Sand spray is a kind of coating, which increases the surface granules;
The frosted is polishing or acid corrosion, causing the surface granules;
obviously easy sandblasting, difficult to have a high difficulty for scrub processing, but the effect is permanent.
