Abstract

The invention relates to a preparation method of nano-silver powder with high sintering activity, comprising: step S1, injecting nano-silver into the first grinding device through a first grinding device feed port for preliminary grinding; step S2, preliminarily grinding nano-silver The second grinding device is injected into the second grinding device through the feed port of the second grinding device and is ground again by the high-pressure airflow, and the nano-silver meeting the particle size is injected into the sintering device through the discharge port of the second grinding device; step S3, the central control unit controls the sintering device, and Nano silver is sintered. In the present invention, by setting the central control unit, according to the unqualified rate of nano-silver particle size obtained, the volume change rate during sintering, the sintering temperature and the sintering time, the output of sintered nano-silver meets the preset standard, and at the same time, the jet flow is adjusted. The frequency, the grinding time of the first grinding device and the dynamic parameters of the power device are used to make the particle size of the love nano-silver meet the preset standard.

Description
