Черный порошок карбида кремния широко используется при полировке и притирке благодаря своей высокой твердости (по шкале Мооса 9,1-9,3) , острым краям и превосходной термической стабильности. Он особенно эффективен для металлов, керамики, стекла, камня и композитных материалов .
Основные свойства для полировки
Высокая твердость — эффективное удаление материала.
Острые, угловатые зерна — обеспечивают равномерное режущее действие.
Термическая и химическая стойкость — подходит для влажной и сухой полировки.
Контролируемый размер частиц — доступно от мелкого до крупного зерна (FEPA, JIS или микронные сорта).
Распространенные применения полировки
Полировка металла
Удаление заусенцев и чистовая обработка нержавеющей стали, титана, алюминия и чугуна .
