Copper slag 20/40mesh abrasive grit for sandblasting

Copper Slag

Copper slag is a by-product of copper extraction by smelting. During smelting, impurities become slag which floats on the molten metal. Slag that is quenched in water produces angular granules which are disposed of as waste or utilized as discussed below.

#Sandblasting

Copper slag is mainly used for surface blast-cleaning. Abrasive blasting is used to clean and shape the surface of metal, stone, concrete and other materials. In this process, a stream of abrasive grains called grit are propelled toward the workpiece. Copper slag is just one of many different materials that may be used as abrasive grit. Rate of grit consumption, amount of dust generated, and surface finish quality are some of the variables affected by the choice of grit material.
The blasting media manufactured from copper slag brings less harm to people and environment than sand. The product meets the most rigid health and ecological standards.

#Construction

Copper slag can be used in concrete production as a partial replacement for sand. Copper slag is used as a building material, formed into blocks. Such use was common in areas where smelting was done. The granulated slag (<3 mm size fraction) has both insulating and drainage properties which are usable to avoid ground frost in winter which in turn prevents pavement cracks. The usage of this slag reduces the usage of primary materials as well as reduces the construction depth which in turn reduces energy demand in building. Due to the same reasons the granulated slag is usable as a filler and insulating material in house foundations in a cold climate. Numerous houses in the same region are built with a slag insulated foundation. 

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 slag.
