Meijun water sandblasting machine IIII type wet negative pressure water sandblasting equipment, suitable for sandblasting room base sand recycling sand.

Our company specializes in sandblasting machines for more than ten years, on the basis of excellent technology and good machine quality.

Water blasting machine MG-FSP7500 is a kind of equipment that complies with national standard discharge and environmental protection standard sand blasting No dust emission, automatic cycle sand collection, one person can sandblast or multiple people can sandblast.

Negative pressure water sandblasting machine application:

Use net compressed air to strongly spray (such as quartz sand, white corundum, ceramic sand, brown corundum, cast steel sand, river sand, etc.) onto the surface of the metal workpiece to grind off burrs, oxide skin, rust, accumulation on the surface of the workpiece. The process of surface defects such as carbon, welding slag, molding sand, residual salt, old paint film, and dirt is called sandblasting.

Sandblasting is often used for surface cleaning of workpieces, such as removing residual sand and high carbon-containing layers on the surface of castings, as well as welding seams of welded parts, to eliminate rust and oxide scale. Rust removal generally uses sandblasting and pickling. The latter is easy to allow hydrogen to penetrate into the steel parts, increase the internal stress and reduce the plasticity, while sandblasting and rust removal does not produce hydrogen embrittlement. Whether it is high carbon steel, high strength steel, or elastic parts, brass parts, stainless steel parts and aluminum parts after sandblasting and entering the next process, the bonding force of the coating or oxide layer can be improved. Co-construction of hard chrome plating and paint is commonly used to clean the surface by sandblasting, and machine tool accessories and tools are often used for matting before opalescent chrome plating. Sand blasting and rust removal is an excellent quality among various surface pretreatment methods. It can not only completely remove the oxide skin, rust, old paint film, oil stains and other impurities on the metal surface, so that the metal surface shows a uniform metal color, but also can make the metal surface obtain a certain roughness, so as to obtain a uniform roughness. surface, and convert the machining stress into pressure, improve the bonding force between the anti-corrosion layer and the base metal and the corrosion resistance of the metal itself. Commonly used in painting, thermal spraying and roughening of plastics. In addition to sandblasting, surface roughening methods include threading method, knurling method, electric spark roughening method, etc.

Sandblasting is divided into two categories: dry blasting and wet blasting. Wet blasting uses abrasives mixed with water to form mortar. In order to prevent metal from rusting, corrosion inhibitors should be added to the water. Dry spraying has high efficiency, rough processing surface, large dust and more abrasive crushing; wet spraying has little environmental pollution, and has certain polishing and protective effects on the surface, and is often used for finer processing.
