銅礦砂 電鍍前底面拋光銅礦砂 金屬磨光銅礦砂銅礦砂簡介:
銅礦砂是從銅礦中開采出來的,然后經(jīng)過選礦成為含銅品質(zhì)較高、精細(xì)的砂狀銅礦。按用途篩選成規(guī)格大小不同的顆粒。
Introduction of copper ore sand:
Copper ore is mined from copper ore, and then it has become a fine sand shaped copper ore with high copper quality. The sizes of different sizes are screened by use.銅礦砂性能特點(diǎn):
銅礦砂顆粒堅(jiān)硬、外形棱角多、噴射效果好、破損率小、含灰率低,作為除銹材料,銅礦砂碰到鐵之后分裂成2-3個(gè)銅礦砂,其形狀不變,鋒利的刃在除銹中效果非常快,并且可循環(huán)利用多次,由于可以反復(fù)利用,其經(jīng)濟(jì)效益大幅度提升。
The properties of copper ore sand:
Copper sand particles, hard shape edges, good spraying effect, low breakage rate, low ash rate, as rust material, copper sand met iron split into 2-3 copper ore, its shape, sharp edge of the rust removal effect is very fast, and can be recycled by many times, can be repeatedly used the economic benefit is greatly improved.銅礦砂理化指標(biāo):
