Water Atomized Copper Powder with low apparent density is a kind of water spray powder reduction than copper powder preparation low loose the method. The existing oxidation reduction method of directly, copper powder for reduction time long, the higher temperature of furnace temperature, can the big use of goods and services, costs are hush drunker; Labor intensity, low efficiency of working procedure, the high cost of transport; Cannot be used in the production of high carrying into action of gunpowder metallurgy intersections.
The confront invention water spray powder reduction than copper powder preparation low loose the method, which is characteristic of the USES annular flow injection of copper focus more fluid atomization, then directly after the atomization of copper pulverisation into prohibitionist pulverise air-dry, the reduction of sintering, crushing, screening processing, get fine particles of the rules is not reunification by copper color pulverise. It can be used inwards Diamond Tools,powder metallurgy parts,Chemical catalyst,carbon paper skirmishes and rubbing stuffs and welding electrodes.
This invention practiced more than focus after drying get water spray of dry powder sintering directly reduction, made shorten reducing fourth dimension, with a depress temperature reducing force out equal earned sintering, greatly cut back the energy consumption and the beneficial effect caused by the system; The labor strength equals small, high efficiency; Can be used in manufacturing high performance of powder metallurgy products.
