【供應(yīng)銅礦砂金剛砂薛先生136/6726/9191】工廠車間地坪用金剛砂 耐磨地坪用金剛砂金剛砂簡(jiǎn)介

金剛砂可以是碳化硅，也可以是棕剛玉，亦可以是黑剛玉，或者是白剛玉。硬度大，大約是莫氏9.5度，一般的是粉狀顆粒，磨碎以后，可以作研磨粉，可制擦光紙，又可制磨輪和砥石的摩擦表面，由砂和適量的碳放在電爐中加強(qiáng)熱制得。

金剛砂原材料經(jīng)過(guò)簡(jiǎn)單加工可分幾個(gè)等級(jí)，篩選分級(jí)等方法制成的研磨材料,硬度很大，大約是莫氏7-8度。一般有黑色，棕剛玉，灰色等多種顏色的顆粒，磨碎以后，可以作研磨粉，可制擦光紙，又可制磨輪和砥石的摩擦表面。粒度大小分粗目，中目，細(xì)目三大類。各種目數(shù)粒度均勻，顆粒形狀均一，成棱叫角晶體，有鋒利的邊緣，磨削力高。金剛砂的磨削力略低于電爐白剛玉，但其任性強(qiáng)，具有介殼狀段口之特性，其優(yōu)點(diǎn)是磨件的光潔度高，砂痕少而淺。磨面細(xì)而均勻，可提高產(chǎn)品質(zhì)量。金剛砂的研磨時(shí)間短，效益高，價(jià)格低廉，可彌補(bǔ)壽命短的不足。

Emery raw materials are made by simple processing of several grades, and the hardness is large, about 7-8 degrees. Generally has black, brown corundum, gray and other color particles, after grinding, grinding can be used as a powder, can be polishing paper, and friction surface of grinding wheel and strop stone. The size of the grain size is coarse, middle and narrow. Various kinds of grain size are uniform, the grain shape is equal to one, the edge is called the Angle crystal, has the sharp edge, the grinding force is high. White corundum emery grinding force is slightly lower than electric, but its willfulness is strong, with conchoidal segment of features, its advantage is a high degree of finish, grinding sand marks and shallow. The grinding is fine and uniform, which can improve the quality of the product. The grinding time of emery is short, the efficiency is high, the price is low, can make up the short life short.
