Abstract
The present invention relates to be used for aluminium powder for paint and production method thereof.With old and useless aluminium foil sheet and the leftover pieces of gathering thereof, by broken, separate, grind, operation such as packing, will obtain qualified aluminium powder, the use of industries such as fuel feeding lacquer; Turn waste into wealth, safeguard clean environment, and be that country saves a large amount of aluminiums; Technology is simple, is easy to promote.
Description
The present invention relates to be used for aluminium powder for paint and production method thereof.
Known aluminium powder is to process with aluminium (aluminium ingot) at present, its process complex process, and difficulty is big, thereby cost is also high.
A kind of old thin production aluminium powder and the production method thereof utilized that the objective of the invention is to avoid weak point of the prior art and provide.
Purpose of the present invention can reach by following measures: gather discarded aluminum slice and leftover pieces, carry out fragmentation, separate then, the product after separating is entered ball mill grind, the product after grinding is packed be product.
The relative prior art of the present invention has following advantage: the one, to turn waste into wealth, and waste and old aluminum slice is to be used as rubbish, can reach more than 98% by gathering its powder purity of processing back, the quality raw materials of purposes such as can paint; The 2nd, processing technology of the present invention is simple, and investment cost is little, can produce on the spot, promotes easily; The 3rd, turn waste into wealth, for country saves a large amount of aluminiums; The 4th, safeguarded the cleaning of environment, promote civilization construction.
The present invention is described in further detail below in conjunction with embodiment: the old aluminium scrap that will collect thin (as the cigarette inner bag) carries out coarse crushing, it is the one-level coarse crushing, its product granularity should be less than 2 millimeters, carrying out the one-level separation then is that wind-force separates, product after separating is carried out two-stage crushing, its product degree of drawing should be less than below 1 millimeter, carrying out secondary again separates, change electrostatic separation over to by the product after the secondary separation, product after the electrostatic separation is entered ball mill to grind, its product granularity requires to reach 250～320 orders, packs then and is the aluminium powder finished product, and its purity reaches more than 98%.(seeing accompanying drawing)
Claims (1)
- A kind of aluminium powder and production method thereof, what it is characterized in that collecting abandons old aluminum slice and leftover pieces thereof, carry out coarse crushing, it is the one-level coarse crushing, its product granularity should be less than 2 millimeters, carrying out the one-level separation then is that wind-force separates, product after separating is carried out two-stage crushing, its product granularity should carry out secondary and separate less than below 1 millimeter again, and the product after separating by secondary changes electrostatic separation over to, product after the electrostatic separation is entered ball mill to grind, its product granularity requires to reach 250～320 orders, packs then and is the aluminium powder finished product, and its purity reaches more than 98%.
