Silicon carbide blast abrasives are the hardest and sharpest abrasives available, providing excellent rust removal capabilities as well as deburring metal, glass, or polishing stone surfaces.
Aluminum oxide and silicon carbide are both widely utilized sandblasting agents; choosing which to use depends on your application and budget.
Hårdhet
Silicon carbide is an extremely hard and sharp material, ranking ninth on the Mohs scale of mineral hardness. Used as an abrasive to cut or grind difficult materials like metal and stone, as well as glass, rubber, wood and paint sandering projects with low cutting pressure such as graining stainless steel finish or finishing stainless steel graining applications, silicon carbide ranks ninth for mineral hardness on Mohs’ scale of mineral hardness.
Hardness makes sand more brittle than other forms of blast media, causing it to break down more easily than other options. Sand can be recycled for shorter blast cycles and works well on materials with lower tensile strength such as aluminum and ceramics; additionally, its hard surface etching properties help prepare them for coating applications.
White aluminum oxide abrasives are ideal for soft metals like aluminum, as they produce an elegant finish without creating excessive heat. White aluminum oxide can also be combined with silicon carbide to achieve desired results.
This type of abrasive material is tough and durable, making it suitable for heavy sanding operations such as working with cast iron. Furthermore, this abrasive works well on harder materials like steel and titanium alloys as well as being available in a range of grit sizes from coarse to fine grit sizes to meet all sanding needs. Furthermore, its cost is also much less than tungsten carbide.
Versatility
Silicon carbide sanding grains are highly versatile. Their hardness enables them to grind both harder materials like metal and rougher surfaces such as concrete, as well as soft materials like wood finishes, stone and rubber – plus their long lifespan ensures they can withstand wear without losing effectiveness – ideal for applications requiring limited downtime.
This versatile blasting solution is often chosen for tasks that require fast material removal. Automotive industries prefer this blaster because of its ability to quickly clear away paint, rust and other defects from car bodies and components; construction companies, welding shops and foundries use them because it quickly cleans away ferrous and non-ferrous metals and glass debris.
Different grades of silicon carbide provide different levels of longevity, coarseness/aggressiveness and friability. Black silicon carbide (Carborundum) is one of the most widely used grades used in wheel, slurry and refractory abrasives, commonly grinding metals and ceramics with less effectiveness on softer materials like wood; additionally it has more durability than brown fused alumina at handling higher temperatures and temperatures.
Alumina-zirconia is an innovative material with greater durability than black silicon carbide, at a more cost-effective rate than diamond. Additionally, its lifetime can outlive aluminum oxide. Alumina-zirconia comes as loose or bonded sanding grains in various grit sizes and formats such as discs sheets and belts and can also be attached to oil-based and water-based compounds via adhesion bonds.
Hållbarhet
CARBOREX blast media remains effective for longer than other blast media, enabling you to achieve superior results with fewer replacements required – saving both time and money as well as decreasing environmental impacts caused by its use.
CARBOREX Abrasives are semi-friable black coarse grain blasting materials designed for various applications. Their semi-abrasive qualities make them suitable for metal lapping, glass grinding and stone polishing as well as deburring and etching processes – plus can serve as an efficient replacement for aluminum oxide when aggressive cutting of low tensile strength metals are required without heat generation issues.
Manufacturers create an abrasive by fusing together high-grade silica sand and finely ground carbon (petroleum coke) at high temperature in an electric furnace at an extremely high temperature, producing carbide particles with sharp, durable edges which can withstand even high pressure sanding applications.
Cooling and solidification processes are employed to avoid undesirable crystalline structures before it undergoes particle size classification to meet established industry standards and customer demands. Once complete, this abrasive material may then be packaged into cartridges for blasting applications or sold individually by weight for general sanding or grinding applications.
Säkerhet
Silicon carbide’s hardness makes it an excellent material to use as blasting media and for wet sanding applications, producing an exceptional finish for metalworking and woodworking applications while its razor-sharp grains cut effortlessly through hard materials like stone. Unfortunately, silicon carbide does not last as long and wears down more quickly with repeated usage than aluminum oxide would.
Silicon and carbon, combined into one chemical compound known as moissanite, is found naturally as an uncommon mineral; however, mass-production has begun since 1893 in powder or crystal form for use as an abrasive. Furthermore, moissanite is often employed in tough ceramic applications like those seen in bulletproof vests as an ingredient of their plates.
Abrasive blasting utilizes abrasive material as its main media because it is both affordable and long-lasting. Specialized machinery projects the abrasive material at high speeds across a surface to remove rust, power away old paint or roughen up surfaces for coatings or other finishing processes.
employees using silicon carbide should take all necessary precautions to protect themselves and other workers when working with this abrasive. This may involve wearing a supplied-air respirator with full facepiece operating under pressure-demand or other positive-pressure conditions to limit exposure, and immediately changing into clean clothing and washing any parts of their bodies that came in direct contact with silicon carbide. If skin contact occurs, workers should change into new attire immediately as well as cleanse any parts that were directly exposed.
