In addition, when the mesh belt resistance furnace is used for quenching, the oil stains on the surface of the workpiece are mixed with dust and other impurity particles, and sintered into stubborn solid grease. When the nitrate is tempered, the above grease and nitro salt form stubborn thermal polymer , It is difficult to completely remove the above dirt during electroplat...

Abstract

The invention discloses a non-toxic electroplating liquid. The non-toxic electroplating liquid consists of a hydrogen peroxide stabilizer, a silicon removing agent and a color fixing agent, wherein the hydrogen peroxide stabilizer is a polyethylene polyamine salt; the silicon removing agent is magnesium silicate; the color fixing agent is epoxy chloropropane; the polyethylene polyamine salt accounts for 41 to 42 percent of the total weight of the non-toxic electroplating liquid; the magnesium silicate accounts for 31 to 32 percent of the total weight of the non-toxic electroplating liquid; the epoxy chloropropane accounts for 26 to 27 percent of the total weight of the non-toxic electroplating liquid. The non-toxic electroplating liquid provided by the invention has the advantages of being non-toxic, high in stability and suitable for continuous operation.

Example Embodiment

[0008] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to make a clearer and clearer definition of the protection scope of the present invention.
[0009] Wherein, the non-toxic electroplating solution includes a combination of a hydrogen peroxide stabilizer, a silicon removal agent and a color fixing agent, the hydrogen peroxide stabilizer is a polyethylene polyamine salt, the silicon removal agent is magnesium silicate, and the The fixing agent is epichlorohydrin, the polyethylene polyamine salt accounts for 41%-42% of the total amount of non-toxic electroplating solution, and the said magnesium silicate accounts for 31% of the total amount of non-toxic electroplating solution. 32%, the epichlorohydrin accounts for 26%-27% of the total amount of the non-toxic electroplating solution, and the magnesium silicate includes magnesium sulfate and silicon dioxide.
[0010] To further illustrate, the polyethylene polyamine salt accounts for 41% of the total non-toxic electroplating solution, the magnesium silicate accounts for 32% of the total non-toxic electroplating solution, and the epichlorohydrin accounts for none. 27% of the total amount of poisonous plating solution. Polyethylene polyamine salt surfactants have good water solubility, both acid and alkali resistance, and most of them have bactericidal effects. Since most of the fiber surface is negatively charged, the quaternary ammonium salt cationic surfactant can neutralize its charge, so it has a better antistatic effect. They can form a hydrophobic oil film on the fiber surface, reduce the friction coefficient of the fiber and make it soft and smooth, so it can be used as a softener. In addition to being used as an antistatic agent and softener, this surfactant can also be used as a hair styling conditioner in hair care products and a leveling and fixing agent in the textile industry. But it has the disadvantage of making machinery rusty, and the price is more expensive. In cleaning agents, it is often compounded with non-ionic surfactants to form sterilization and disinfection cleaning agents.
[0011] In further explanation, magnesium silicate is a hydrous magnesium silicate with indeterminate composition, generally crystallized into pentahydrate, containing MgO> 20%, SiO2> 45%. The product is a white powder that is odorless, tasteless, and non-gritty. It is insoluble in water or ethanol, and is easily decomposed by inorganic acid. It reacts with sulfuric acid to produce magnesium sulfate and silicon dioxide. The latter is insoluble in water and acid and can separate silicon and magnesium. It is slightly hygroscopic in the exposed air.
[0012] In further explanation, epichlorohydrin is a colorless liquid with a chloroform-like odor, volatile and stable. It can be miscible with ethanol, ether, chloroform, trichloroethylene and carbon tetrachloride, but is insoluble in water and not miscible with petroleum hydrocarbons. Relative density (d204) 1.1812, melting point -25.6°C, boiling point 117.9°C, refractive index (n25D) 1.43585, flash point (open cup) 40°C, flammable, moderately toxic, LD50 (rat, oral) 90~ 210mG/kG. It is narcotic. Animal experiments have proved potentially carcinogenic. The invention provides a non-toxic electroplating solution, which has the advantages of being non-toxic, promoting dissolution, and improving current density.
