For example, a high hardness mineral used in the sandblasting industry to prepare and clean surfaces. At the time of iron separation from the iron furnace; Are separated from iron ore impurities. During smelting in the factory, the grout impurity floats on the molten metal and an angle granule is formed. These materials are either disposed of as waste or used as abrasives.
Copper powder is a mixture of silicates and metal oxides that remain after the impurities have cooled. These materials are used in solid form in sandblasting and shot blasting industries for cleaning and painting surfaces.
Copper slag; There are different types, each with different uses. Matte mesh and glossy mesh are two types of high quality of this element.
What is the advantage of silica over silica?
Unfortunately, it is a substance that does not cause any environmental pollution and is less expensive than silica due to its large volume on Earth.
* Higher speed
* Reduced cost
* Less dust production
* Increase work efficiency
* Higher increase in surface quality
* Protects the health of employees
* Free silica (crystallized) less than 1%
* Corner
Application of proverbs
Using high pressure blasting equipment, the most suitable material in terms of quality and price to remove rust, sediment and prepare surfaces for painting is used in shipbuilding, bridge construction, steel industry and..
* Refineries
* Oil rigs
*petrochemical
* Marine and shipbuilding industries
*pipelines
* Power plants
* Cement industry
* Parts manufacturing industries
Reasons for choosing the medium instead of silica sand
Considering the use of silica sand as an abrasive, which is more common than other abrasives in our country, the evaluation of this product with silica sand is as follows.
According to the classification of slag abrasives in SSPC-AB1 standard, the mesh with a minimum of free silica (crystallized silica) below 1% is in category A, which does not cause any environmental pollution.
While the percentage of free silica in silica sand due to its purity reaches over 90%, the resulting dust during blasting operation causes two dangerous diseases of silicosis and lung cancer.
The minimum hardness of copper slag (copper bar) according to the standard (ISO-11127-4) is seven mice, which is measured by glass slide method and has much higher hardness compared to silica sand.
As a result of the impact of this abrasive on the surfaces, cleaning of any mass and rust, climbing oxides, and old coatings with high thickness can be done easily and surface preparation is provided by providing the maximum adhesion between the surface and the coating in the best possible way.
High mesh density (3.5 gr / cm 3) is another factor that accelerates blasting.
The abrasive hits the surface more rapidly. The minimum density is defined in ISO-11127-3 as 3.3 grams per cubic centimeter.
