Abstract

The invention discloses a nickel chrome wire which is passivated. The passivating treatment comprises the following steps: (1) feeding 1 to 2 weight parts of alkyl polyoxyethylene oxide, 0.7 weight part of disodium hydrogen phosphate, 3.2 weight parts of tannic acid, 1.1 weight parts of sodium persulfate and 0.8 weight part of lauryl trimethyl ammonium chloride into 25 weight parts of deionized water in sequence for uniform stirring; (2) then feeding 1.3 weight parts of benzotriazole, 4.2 weight parts of polyacrylic acid, 1.3 weight parts of isomerous tridecanol polyoxyethylene ether phosphate, 0.3 weight part of zinc dihydrogen phosphate and 0.7 weight part of zinc dialkyl dithiophosphate in sequence, continuously stirring the components till the components are fully and uniformly mixed,thus preparing a passivating treatment solution; and (3) putting the nickel chrome wire into the passivating treatment solution for passivating treatment at treatment temperature of 50 DEG C for 30 s,taking out the nickel chrome wire, cleaning the nickel chrome wire with pure water, and drying the nickel chrome wire. The nickel chrome wire disclosed by the invention is high in performance after being subjected to the passivating treatment, and is high in surface smoothness.

Description

technical field [0001] The invention relates to a nickel-chromium wire. Background technique [0002] The oxidation resistance, abrasion resistance, corrosion resistance, heat resistance, cold resistance and weather resistance of the existing nickel-chromium wire need to be improved, and the surface finish is not ideal. Contents of the invention [0003] The object of the present invention is to provide a kind of nickel-chromium wire, which forms a uniform passivation protective film on the surface after passivation treatment, has excellent oxidation resistance, abrasion resistance, corrosion resistance, heat resistance, cold resistance, weather resistance, and the surface Good finish. [0004] In order to achieve the above object, the technical solution of the present invention is to design a kind of nickel-chromium wire, which is through passivation treatment, and said passivation treatment comprises the following steps: [0005] 1) Add 1 to 2 parts by weight of oxidiz...
