Abstract

The invention relates to the technical field of industrial copper powder production, and discloses a production system for producing industrial copper powder based on pyrolysis and hydrogen embrittlement principles. The production system includes a horizontally rotatably arranged rotary furnace, a multistage-cooling spiral system, a turbine crushing system and a copper fine powder ball mill; the rotary furnace is placed in a heating furnace, a heating ring chamber is formed between the rotary furnace and the heating furnace, and the rotary furnace is heated by fuel combustion in the heating ring chamber; the rotary furnace is connected with the multistage-cooling spiral system, and copper particles formed after heating pyrolysis in the rotary furnace are spirally conveyed and cooled by themultistage-cooling spiral system; the turbine crushing system crushes the copper particles conveyed by the multistage-cooling spiral system, and removes pyrolyzed carbon black; and the copper fine powder ball mill grinds the copper particles processed by the turbine crushing system to form the industrial copper powder. The production method realizes the preparation of high-purity ultrafine copperpowder (1000-1250 meshes), the whole preparation process achieves energy saving and environmental protection, and the prepared industrial copper powder has good quality and high grade.

Description

technical field [0001] The invention relates to the technical field of industrial copper powder production, in particular to a production system for producing industrial copper powder based on pyrolysis and hydrogen embrittlement principles. Background technique [0002] Industrial copper powder is widely used in powder metallurgy, electric carbon products, electronic materials, metal coatings, chemical catalysts, filters, heat pipes and other electromechanical parts and electronic aviation fields. [0003] Printed circuit board (referred to as PCB) is the most basic and active electronic component, and is an indispensable and important part of the electronics industry. A United Nations report pointed out that more than one-third of the world's electronic products are produced in China, and 70% of the world's electronic waste also flows to China. In 2010, my country's PCB production accounted for 38.1% of the global PCB market, ranking first in the world; it is estimated th...
