玻璃打砂用砂sand for sand blasting無塵砂玻璃噴砂
無塵砂是玻璃噴砂中效果非常好的新型產(chǎn)品，廣泛用于清理，和玻璃、金屬表面強化處理的一種獨特性的磨料。主要用于噴砂設備，玻璃噴砂效果非常好。無塵砂經(jīng)高溫冶煉而成，制造中要熔成球狀，再退火以除去內(nèi)應力和防止破損。加入特種礦石經(jīng)高溫燒制成， 無棱角，外型球體狀。
Free-dust sand is a kind newly environmental protection material ,with raw material of bauxite,coal and so on,It is used in the fields of Glass sandblasting and Abrasive tools.Free-dust sand is the substitute for Middle and low intensity emery sand such as Quartz sand, glass balls and metallic balls.
