Abstract

The invention discloses a preparation method of an electrode plate for a copper-silver ion generating device. The preparation method comprises the following steps: (1) preparation of raw materials: soaking electrolytic copper and silver ingots in a mixed solution formed by mixing sulfuric acid with concentration of 20% and hydrofluoric acid with concentration of 5% for 20-40 min, and then cleaningthe ingots with pure water for later use; (2) smelting: placing 70%-99% of electrolytic copper and 1%-30% of silver ingots into a crucible, and placing the crucible in a double vacuum smelting devicewith a constant electromagnetic field at vacuum of 10<-3>, rotating the crucible at 1000-1200 DEG C to form electromagnetic bidirectional stirring, keeping the temperature for 100-150 min, and performing cooling with ionized water for 30 min or shorter to obtain copper-silver alloy; (3) cold processing: performing cold forging, cold rolling and cold annealing on the melted copper-silver alloy; (4) stamping: stamping the copper-silver alloy to obtain the electrode plate for the copper-silver ion generating device. The invention also discloses a product prepared by the method.

Description

Technical field [0001] The invention relates to the field of disinfection and sterilization, in particular to a method for preparing an electrode plate for a copper-silver ion generating device, and a product prepared by the method. Background technique [0002] At present, the substances used for disinfection and sterilization on the market are mainly divided into physical disinfection and chemical disinfection. Among them, chemical disinfection is widely used. However, disinfection by chemical reagents can easily pollute the environment. Physical disinfection is relatively safe and can reduce environmental pollution. At present, physical disinfection is mainly used for disinfection of swimming pool water, disinfection of livestock water, disinfection of household water and other domestic water disinfection and disinfection. The principle is mainly to sterilize by copper ion, silver ion, ultraviolet light, etc. [0003] Silver is one of the trace elements in human tissues. A smal...
