Learn how to assess rusted steel, choose between SGA 20/40 and SGA 30/60, set a trial blast and verify cleanliness and surface profile before coating. Read More

As is known to all, ordinary steel usually goes through the process of sand blasting and derusting before use, which can remove rust, oxide scale and other sundries. Before pickling and passivation, stainless steel will also undergo sandblasting to clean the surface, remove the possible oil stains o Read More

Sa 1, Sa 2, Sa 2½ and Sa 3 are visual cleanliness grades for blast-cleaned steel. Learn what each grade means, whether garnet abrasive can achieve Sa 2½ or Sa 3, and which blasting and inspection factors affect the final result. Read More

1） Not clean washing, or even not washingSome production and processing enterprises in order to save costs in the water washing process, the amount of water is not enough or the water quality is very poor, or even no water washing, resulting in high mud content of the abrasive.2） Insufficient magnet Read More

If there are too many impurities, there will be abnormal color spots or spots on the abrasive jet surface, and the surface is not smooth;The roughness of the abrasive sprayed surface will be uneven. If anti-corrosion coating is required in the later stage, the adhesion of the coating will be uneven, Read More

1.Excellent surface cleaning effectIt can penetrate deep into holes and uneven parts, and completely remove scale, rust, soluble salt and other dirt. After sandblasting, there are no embedded objects, no unfavorable protrusions and pits, and it can easily obtain the highest cleaning level of SA3. Th Read More

In sandblasting, an important indicator that is often detected is electrical conductivity, that is, the electrical conductivity of the object. This is to detect the soluble salt content of the object after blasting. Soluble salts are a potential threat to objects being blasted. It affects the coatab Read More

First, sandblasting grade garnet can be used for sandblasting, rust removal, decontamination, grinding steel, etc., for metal surface treatment in shipbuilding and large-scale complete equipment manufacturing, ship maintenance, etc.The second is to manufacture molding sand, sintered abrasives and co Read More

1. The humidity of the air. When the relative humidity in the air reaches 85% or the surface temperature of the sandblasted object is less than 3 degrees Celsius, the sandblasting operation should be stopped. Once it gets wet, it will lose its effectiveness. Read More
