The Role of Abrasives in Industry
Abrasives are indispensable in a myriad of industrial operations. They cut, молоть, polish, and remove excess material, making them essential in manufacturing, строительство, и автомобильной промышленности. From shaping a piece of furniture to polishing a car’s surface, abrasives are the silent workers behind the scenes.
The Production of Silicon Carbide Abrasives
Silicon carbide abrasives don’t just appear out of thin air. There’s a meticulous process behind their production, tailored to forge their unique properties.
Производственный процесс
The production journey begins with a high-temperature reaction between silica sand and petroleum coke. Результат? A lump of raw silicon carbide. This lump is then grounded, treated, and graded into abrasive grains of varying sizes and specifications. An intriguing process, не так ли?
Key Features of Silicon Carbide Abrasives
What sets silicon carbide abrasives apart? These abrasives are incredibly hard and sharp. They’re heat-resistant and durable, making them suitable for heavy-duty applications. Their ability to maintain sharpness even under intense pressure is another feather in their cap.
Типы абразивов из карбида кремния
Like a spectrum of hues, silicon carbide abrasives come in different types, each with its own strengths.
Black Silicon Carbide Abrasives
Черный карбид кремния abrasives are renowned for their toughness. With a lower purity level, they’re ideal for materials like stone, чугун, и цветные металлы.
Зеленые абразивы из карбида кремния
С другой стороны, зеленые абразивы из карбида кремния, with higher purity levels boast superior properties. They exhibit low thermal expansion and strong oxidation resistance, making them thermally stable. Their excellent chemical resistance allows them to resist both strong acids and alkalis. более того, they have high refractoriness and excellent thermal shock resistance, suitable for self-bonded ceramics, honeycomb ceramics, and foam ceramics. Their high wear resistance and hardness (Мооса 9.5), coupled with strong self-sharpening and grinding power, make them apt for grinding and polishing cemented carbide, титановый сплав, and quartz glass. Окончательно, their high-temperature resistance, with a melting point of 2600 degrees Celsius and maximum operating temperature reaching 1900 градусов Цельсия, is a bonus when applied to the inner wall of engines, enhancing the engine’s lifespan.
