In this article, I will detail the principles, application methods, advantages and disadvantages of the sandblasting process.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is sandblasting?<\/h2>\n\n\n\n<p>Sandblasting is a compressed air-powered surface treatment technology that forms a high-speed jet beam to blast (e.g., sand, pearl salts, sodium bicarbonate, glycine powder, silver, etc.) at high speeds onto the surface of the workpiece or object to be treated. The beaded medium is guided to the surface of the material. The target surface is smooth, clean and shiny by friction reaction.<\/p>\n\n\n\n<p>Sandblasting is a traditional and time-consuming process for large and complex materials with different shapes. As a result, the concept of sandblasting was patented and introduced in the United States in 1870. The concept of sandblasting comes from the natural phenomenon of sand erosion caused by dust in desert areas.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is sandblasting used for?<\/h2>\n\n\n\n<p>Shot peening is a widely used treatment process. It plays many roles in the production and manufacture of metal products, removing oxidized skin, rust, dirt, scratches and other undesirable substances or defects. It makes the metal products have a better appearance and meet the needs of customers.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>When to choose sandblasting<\/strong>appliance<\/h2>\n\n\n\n<p>Sandblasting is used in the following cases:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>1. CNC machining milling cutter and other tools in the processing surface to produce scratches, scratches, swirl scratches, need to remove the product appearance uniform .<\/li>\n\n\n\n<li>2. CNC machined surface products with small burrs, eliminating edge bumps, preventing scratches to the hand, safer to use.<\/li>\n\n\n\n<li>3.CNC machining, aluminum alloy casting surface produces oil, sandblasting to remove oil, make the surface more consistent and beautiful.<\/li>\n\n\n\n<li>4. Aluminum alloy casting requires additional surface treatment such as plastic spraying, plating, painting, etc. to facilitate adhesion and remove the interference of surface magazines.<\/li>\n\n\n\n<li>5. By using different sizes of sand blasting, the roughness of the product surface is changed to produce different uniform roughness on the product surface to meet the requirements of use (e.g. anti-slip).<\/li>\n\n\n\n<li>6. Remove residues or unwanted coatings from the surface of the product without damaging the material.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">How the sandblasting process works<\/h2>\n\n\n\n<p>Compressed air is used as the power source for the sandblasting process. The sandblasting abrasive is sprayed at high speed onto the surface of the workpiece to be treated by the high-speed jet beam formed by the compressed air. The high-speed jet abrasive has a strong impact on the surface of the workpiece and can remove dirt, rust, coatings and other attachments on the surface of the workpiece. While polishing the surface material, the abrasive cuts the surface of the workpiece, thus removing material and roughening the surface. To obtain different degrees of roughness, the grain size of the abrasive and the jetting speed can be adjusted as needed.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Tools for sandblasting<\/h2>\n\n\n\n<h2 class=\"wp-block-heading\">Blasting Cabinet<\/h2>\n\n\n\n<p>Sand blasting machine is the core equipment of sand blasting treatment, which is used in sand blasting places. In order to ensure the smooth running of the sandblasting process and protect the safety of the operators, it must be manufactured with top material technology.<\/p>\n\n\n\n<p>The common sandblasting cabinet is welded with strong, high thickness steel, which effectively blocks the flight of abrasives during the sandblasting process. Strong support legs stabilize the blast cabinet so that it does not shake during operation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">sandblast abrasive<\/h2>\n\n\n\n<p>Sandblasting abrasives are one of the decisive roles in sandblasting treatment through the selection of different materials such as steel shot, quartz sand, aluminum shot, glass and plastic. (Quartz sand glass abrasive can make the surface finer and produce a matte effect, steel balls have a stronger surface treatment ability, aluminum oxide has a whitening effect, and plastic media is less strong and can provide a higher precision) Different sizes are available. (Strong sandblasting treatment effect with large particles and rough surface, poor sandblasting effect with small particles and smooth surface.) <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">guns<\/h2>\n\n\n\n<p>The sand blasting gun is the key component of the sand blasting machine. Without sand blasting cabinet, without sand blasting environment and without sand blasting gun, sand blasting is not possible. Depending on the method of use and the type of abrasive, there are various models to choose from. Hand-held (easy to operate and more accurate), foot pedal room remote operation (easier), and other types.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Sandblasting Gloves<\/h2>\n\n\n\n<p>Sandblasting gloves are hand protection specifically designed for sandblasting operations. When using a hand-held sandblasting gun, the sandblast splashes can damage people's hands. At this time, wearing safe and comfortable sandblasting gloves can effectively avoid sandblasting damage, and comfortable gloves can allow you to accurately control the sandblasting gun.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Advantages and disadvantages of sandblasting<\/h2>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-flow wp-block-group-is-layout-flow\">\n<p><strong>Benefits include.<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Thoroughly clean surfaces<\/strong>: Sandblasting completely removes grease, dirt, oxidized layers and other impurities from the surface of the material, leaving the surface very clean.<\/li>\n\n\n\n<li><strong>Improvement of surface roughness<\/strong>: Blasting creates uniformly fine concave and convex surfaces on the surface of the material, increasing the surface roughness and thus improving the adhesion of coatings, adhesives and coatings on the surface of the material.<\/li>\n\n\n\n<li><strong>Enhanced corrosion resistance<\/strong>: Sandblasting exposes the natural surface of a material, eliminating minor depressions and cracks that can be the starting point for corrosion.
