【供应铜矿砂金刚砂薛先生136/6726/9191】工厂车间地坪用金刚砂 耐磨地坪用金刚砂金刚砂简介

金刚砂可以是碳化硅，也可以是棕刚玉，亦可以是黑刚玉，或者是白刚玉。硬度大，大约是莫氏9.5度，一般的是粉状颗粒，磨碎以后，可以作研磨粉，可制擦光纸，又可制磨轮和砥石的摩擦表面，由砂和适量的碳放在电炉中加强热制得。

金刚砂原材料经过简单加工可分几个等级，筛选分级等方法制成的研磨材料,硬度很大，大约是莫氏7-8度。一般有黑色，棕刚玉，灰色等多种颜色的颗粒，磨碎以后，可以作研磨粉，可制擦光纸，又可制磨轮和砥石的摩擦表面。粒度大小分粗目，中目，细目三大类。各种目数粒度均匀，颗粒形状均一，成棱叫角晶体，有锋利的边缘，磨削力高。金刚砂的磨削力略低于电炉白刚玉，但其任性强，具有介壳状段口之特性，其优点是磨件的光洁度高，砂痕少而浅。磨面细而均匀，可提高产品质量。金刚砂的研磨时间短，效益高，价格低廉，可弥补寿命短的不足。

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.
