[Previous technology] At present, in the industrial industry, electroplating process towels are highly toxic with cyanide electroplating solution. Because this electroplating operation must be performed at a temperature of 70 to 80 degrees Celsius, during this process, Its electroplating is because the content of free cyanide is too high. During the inspection, the operator is vulnerable to the danger of cyanogen poison, and the waste electric boat fluid produced after the process also contains the same proportion of free cyanide. And cyanide compounds, therefore, considerable waste of equipment costs (such as heating equipment, cooling equipment, wastewater discharge treatment, etc.) is required for the treatment of sewage and waste water discharge from the jade factory, or it will not only cause serious damage to the environment (for example, Preservation of toxic substances, depletion of waste electricity, sewage discharge ...), will also face severe environmental sanctions, such as closing the factory or relocating products, as well as fighting against environmental regulations, increasing operating costs. fate. Not only does it reduce the competitiveness of the product, but also the consumer's approval; the safety of the riders' operations and the potential for unpredictable crises. [Content] The present invention is a non-cyanide normal temperature electric ore silver-electricity ore bath, which replaces the conventional compounds in the electric ore liquid with chlorine compounds. In addition to avoiding the danger of cyanide poisoning, it can also be used in the process The work / plate temperature is reduced to warm, and the quality of the finished silver plating layer can also be compared with the results of conventional cyanide compounds. The non-cyanide recording solution can be used in Electricity is still carried out at f temperature, and it is normal to make _ Yugao Industrial 20Q526816 safety standard, commissioner / low-income counties, Nana Optoelectronics _ Guanqi-the production of all-metal stopper nuts and other money and silver products. The king of the hall application is due to the production process of the present invention. She is faceless and non-hazardous. In the treatment of her waste liquid, it should meet the standard of L ° / tail water discharge; The King of Work avoids the danger of cyanide poisoning during cropping; for environmental conservation, it avoids the persecution of self-exhibiting cyanide compounds by the severe cyanide compounds. In addition, the invention not only reduces the cost of anti-virus equipment installed by the operator during the processing process, but also reduces the cost of equipment such as waste Wei liquid and sewage discharge. It not only increases product competitiveness and reputation, but also allows for easy access The recognition of customers and environmental groups in Europe and the United States. [Performance] The present invention is a non-cyanide room temperature electric shock 触, which is composed of 2g / 1 ~ i〜1 silver salt, 200g / l ~ _g / 1 active conductive salt, 10ml / 1 ~ 5. ml / l, paste ^ and gloss agent 'The rest is composed of water, the main feature is to replace silver cyanide (AgCN) with silver salts such as silver chloride or desert silver, which can be applied to silver plating at room temperature. The manufacturing process not only reduces the toxicity of cyanide compounds to the workers during the plating operation, but also avoids the adverse effects of personnel working under high temperature conditions for a long time. The preferred embodiment of the present invention is described in detail with the illustration of the first figure as follows: Silver plating pretreatment (step 10): The pretreatment is to remove oxides, hydroxides or grease on the substrate; immersion in acid (step 11) The purpose is twofold: one is to remove the thin oxide film formed on the metal surface; the other is to increase the surface activity of the substrate to facilitate the silver plating process; 200526816 washing before plating (step 12): removing the dirt on the substrate; Pre-mineralized nickel (step 13): Silver is not easy to adhere to the surface of non-recorded steel, so fiber must be recorded on the base material of non-steel steel to increase the adhesion of silk substrate. In addition, pre-mineralized nickel can also increase the surface of the substrate. Active; Wash after pre-nickel plating (step 14): After the pre-nickel nickel, wash the remaining compound solution above; electro money silver (step 15): include silver salt, active conductive salt, buffer, chelating agent, gloss agent And water according to the ratio _ formulated into a liquid for the Wei bath, the temperature of the liquid is normal temperature, the electric and ore parameters of its electrolytic silver power ore are controlled within the range of 0. 〇5 ~ 3 · _m2 ^ density, after 5 ~ 10 minutes Electroplating time can achieve the effect of electroplating; Step 16): After passing the money silver, Taixian's residual compound liquid; and drying the finished product (Step 17): After the complete key silver process, place the finished product in a shaded place, wait for air drying , The finished product is ready to use. In summary, the non-cyanide room temperature electroplating silver electric ore bath invented in this case has industrial applicability, novelty, and progress, and meets the requirements of invention patents. What is described above is only the preferred embodiment of the present invention, and is not intended to limit the scope of implementation of the present invention. That is, according to Ben Fa Lu Yueshen. Equal changes and repairs in the scope of monthly patents [Simplified illustration of the drawing] The meanings of the figures are as follows:-The figure of the electroplating steps of the non-cyanide room temperature electroplating silver electric money bath invented by Tulin Surface morphology of the bell layer of a non-cyanide room temperature electro-smelting silver electric money bath
