What is sandblasting? Blasting is powered by compressed air, to form a high-speed jet beam will spray material (copper sand, quartz sand, silicon carbide, iron ore, Hainan sand) high-speed jet to the surface to be processed, so that the surface of appearance or shape of the outer surface changes due to impact and abrasive cutting action on the workpiece surface, the surface of the workpiece to obtain a roughness of different cleanliness, the mechanical properties of the surface is improved, thus improving the resistance of the workpiece fatigue resistance, which increases the adhesion between the coating and extend the durability of the coating, the coating also helps leveling decoration. The quality of pre-blasting treatment process, affecting the coating adhesion, appearance, moisture-resistant coating and corrosion resistance and other aspects. Pre-treatment did not work, rust will continue to spread in the coating, the coating into a piece off. After a clean surface and generally simple piece carefully cleaned, coated with exposure method comparison, life can be a difference of 4-5 times. Surface cleaning in many ways, but the most commonly accepted method is: solvent cleaning, pickling, hand tools, power tools. Sandblasting is the use of compressed air to blow out a quartz-speed method to clean the surface of the part. Factory also called blowing sand, not to rust, oil can also incidentally, is very useful for painting. Commonly used in parts of the surface rust; surface modification on the part (a small market selling is wet blasting machine for this purpose, usually sand corundum, medium is water). Sandblasting is generally used rust, oil, and make the substrate surface roughness sufficient, the substrate surface is made before the coating process step. Sand blasting Level: namely cleanliness, representative of international standards, there are two: one is the United States 85 years to develop "SSPC-"; second is 76 years in Sweden developed "Sa-", which is divided into four levels, respectively To Sa1, Sa2, Sa2.5, Sa3, customary international common standards, as detailed below: Sa1 level - equivalent to the U.S. SSPC-SP7 class. Using the general simple manual brushing, abrasive polishing method, which is the lowest level of the four medium cleanliness, the protective coating is only slightly better than the treatment of the workpiece is not used. Sa1 level processing technology standards: the surface should not be visible oil, grease, residual oxide, rust, and paint residues and other contaminants. Sa1 level also called hand-brushing cleanup levels. (Or cleaning grade) Sa2 level - equivalent to the U.S. SSPC-SP6 class. Using blast cleaning method, which is the lowest level of sandblasting, that general requirement, but for protection than manual brushing coating to improve the lot of cleanup. Standard processing techniques Sa2 level: not to be visible greasy surface, dirt, scale, scale, paint, oxides, corrosion, and other foreign matter (except for the defect), but not limited to defects per square meter than the surface 33%, which may include a slight shadow; slight discoloration due to small number of defects, corrosion caused; descaling and paint defects. If the datum surface dents, slight rust and paint will be left in the bottom of the dent. Sa2 level also called commodity cleanup level (or industrial). Sa2.5 level - is widely used in industry and can be used as the acceptance level of technical requirements and standards. Sa2.5 level also called near-white cleanup level (near white-or the white level). Sa2.5 level technical standard treatment: the same as the first half of Sa2 requirements, but the defect is limited to no more than 5% per square meter surface, which may include a slight shadow; slight discoloration due to small number of defects, corrosion caused; descaling and paint defects . Sa3 level - equivalent to the U.S. SSPC-SP5 grade level, is the highest level of industrial processing, also known as white cleanup level (or white level). Sa3 level technical standard treatment: the same but with a level of 5% Sa2.5 shadow, defect, corrosion and so had to exist.
