Silicon carbide is one of the hardest blasting media available, making it ideal for multiple applications and uses. Suction blast and pressure blast systems both utilize this material which can even be recycled up to 20 times due to its hardiness.
These tools are perfect for deburring machined parts and castings, etching contaminants from surfaces and prepping them for painting or other coatings, shaping plastics or mixed materials as well as helping shape or smooth them out.
Coarseness
Silicon carbide blasting media is one of the hardest-working blasting materials. Durable yet flexible, its long lifecycle in your blast cabinet allows you to get more done before needing to refill it again – an advantage when working on roughening new parts to facilitate painting or bonding.
Silicon carbide grit blasting produces an angular profile similar to shot, yet with greater aggression and harder hardness than its counterpart – making it an excellent surface cleaner for fiberglass, metal, stone and masonry surfaces as well as reverse circulation blasting processes for stainless steel surfaces.
Black silicon carbide blasting’s coarse grit can also be utilized for deburring, an essential process to eliminate imperfections and create uniform edges on machined or cast components. Its use in green energy products such as PEM electrolyzer membrane materials is especially advantageous, helping ensure they are free of contaminants prior to coating.
This type of blasting abrasive is also popular for creating controlled etches on glass and other materials with portable abrasive blasting systems, making it the go-to choice among artists for etching patterns onto glass surfaces and prepping surfaces for carving or construction projects.
Prepping the Surface for Coating
An effective coating application depends on many factors, including proper surface preparation. When applying protective or adhesive bonding coatings, ideally they should be clean and dry to avoid moisture expansion during curing causing bubbling or holes in finished coatings – which abrasive blasting and cleaning services can assist with.
Silicon carbide grit can help prepare a surface by roughening it up, creating an adhesive surface. As paint is applied to an object’s surface, its ridges will grab onto it as it’s being applied and ensure that its finish remains secure and long-term.
Surface prep entails eliminating corrosion, oil or grease on a part or structure surface to enable proper adhesion of coating or bonding material to the structure and maximize its benefits. There are various techniques for surface preparation available – chemical treatments or mechanical abrasion can all help bring about this desired goal – though for maximum effectiveness and compliance with safety standards it is advised that professional surface preparation services be sought out for this process.
Non-Slip
Silicon carbide is one of the toughest blasting media available. Due to its hard surface and high hardness, silicon carbide makes an excellent choice for removing coatings, rust and scale to create an ideal surface profile for adhesive bonding. Furthermore, silicon carbide milling nonferrous materials is used along with polishing tough materials like ceramic parts using direct pressure blasting systems as well as suction blasting systems – either alone or alongside aluminum oxide for polishing finish removal and removal, both options being friable depending on application requirements.
At Washington Mills, silicon carbide grit is manufactured via carbothermal reduction of natural crystalline silicon with carbon dioxide at high temperatures, then cooled, milled, and classified according to size to meet industry standards. Crushing, milling and classification equipment produced grains that meet ANSI (North America), FEPA (Europe) and JIS (Japan) standards for grains and powders produced.
Silicon carbide’s hard, angular particles allow it to exhibit excellent cutting and grinding abilities, making it suitable for rock tumbling barrels, gem cutting and lapidary work. Silicon carbide is also widely used as part of ballistic armour ceramics; one study by Chabera et al found that composite ceramics with silicon carbide steel backing had higher shear strength values at impact velocities up to 7.62mm R B32 projectile impact velocities than those using alumina as backing at impact velocities of 7.62mm R B32 projectile impacts than those with alumina steel backings at impact velocities of 7.62mm R B32 projectile impacts.
Recyclable
Silicon carbide, commonly referred to as corundum (/krbnm/), is an eco-friendly abrasive blasting material made of silicon. It features hard, durable surfaces with low thermal expansion and shock resistance; thus making it suitable for power blasting applications that remove rust or prepare surfaces for coatings. Furthermore, doping this ceramic material may increase its performance as a wide bandgap semiconductor device.
Manufacturers use silicon carbide to form blocky, angular grains that closely resemble diamond on Mohs’ scale of hardness. Unlike soft blasting media, which degrades over repeated use, silicon carbide doesn’t degrade and can even be recycled up to 20 times before becoming less effective.
This abrasive is designed for use with suction or pressure blast systems and has numerous applications across numerous industries such as aerospace, telecommunications and energy. For instance, this material plays an essential role in preparing titanium materials used in PEM electrolyzer membrane coatings for coating purposes.
