Copper slag with high hardness, shape of a water chestnut, injection effect is good, compared with quartz sand the rust removal effect than quartz sand is good. 
1. Many water chestnut form, efficiency faster than quartz sand, because quartz sand jet out after met iron into a powder and round shape, and copper ore iron met after split into 2-3 copper ore, its shape is changeless, the sharp edge of the rust removal effect is very fast, can be recycled three times. And quartz sand for shape into a ball and cleaning effect is greatly reduced.
2, quartz sand because of its encounter iron to the formation of the dust and causes pollution of the environment, the workers easier occupational disease, iron and steel panel forming a layer of quartz powder, under the influence of word order construction and construction quality, the copper ore without the above situation, this is also so for many years large anti-corrosion company and large shipyard to switch to the cause of the copper ore.
