Applications of Silicon Carbide Abrasives
Grinding and Polishing
Silicon carbide abrasives are commonly used for grinding and polishing hard materials such as metals, ceramică, si sticla. They can be used in both wet and dry grinding applications and produce a high-quality finish
Sandblasting
Silicon carbide abrasives are used for sandblasting to remove paint, rust, and other coatings from surfaces. They are effective at removing surface contaminants without damaging the underlying material.
Unelte de tăiere
Silicon carbide abrasives are used to produce cutting tools such as saw blades and drill bits. They can cut through hard materials such as metals, ceramică, and glass with ease.
Materiale refractare
Silicon carbide is used in the production of refractory materials, which are used in high-temperature applications such as furnace linings and kiln furniture.
Electronic Components
Silicon carbide is used in the production of electronic components such as diodes and transistors. It has excellent thermal conductivity and can withstand high temperatures, making it ideal for use in electronic applications.
Coatings and Surface Treatment
Silicon carbide abrasives are used to produce coatings and surface treatments for metals and other materials. These coatings can improve the durability and wear resistance of the underlying material.
Types of Silicon Carbide Abrasives
Carbură de siliciu negru
Carbura de siliciu neagră este un produs abraziv utilizat pe scară largă, cu rezistență excelentă la uzură, duritate ridicată, densitate mare, impurități reduse și alte avantaje, folosit în mod obișnuit în șlefuirea prin sablare, lustruire, măcinare liberă, realizarea diverșilor abrazivi, etc..
Carbură de siliciu verde
Carbura de siliciu verde este fabricată din nisip de cuarț și cocs de petrol rafinat într-un cuptor cu rezistență, datorită proprietăților sale chimice relativ stabile, Conductivitate termică ridicată, coeficient scăzut de dilatare termică, și rezistență bună la uzură.
