Description of the Invention: [Technical Field] The present invention provides a structure of a high-purity stainless steel cable and a treatment method thereof, mainly for degreasing and polishing a stainless steel wire manufactured by knitting, which can be effectively degreased by an effective And Electro Polishing (Ep)' to enhance the use of stainless steel wire in the appearance of sturdy appearance and use of the life to increase the stainless steel cable. [Prior Art] The stainless steel wire used in the industry is mainly made by the shape of the product required for the stainless steel wire to produce the steel wire of the preset strength'. The de-grease cleaning of the non-steel wire that has been completed is: In the manufacturing process, the existing stainless steel wire is squeezed, which causes mechanical damage (ie, thick chain surface) on the surface of the finished product, so that the finished product of 5 MW or steel wire is in long-term contact with the outside world. It will affect its normal service life. Among them, the general non-scale steel cable itself and the mechanical damage caused by the weaving process: = the treatment can not completely remove the residual oil, resulting in no recording mouth, is not yellow. In the general stainless steel cable: ~, has a good anti-corrosion ability is the surface of a layer of chromium-rich two film ° Hai oxide film thickness is related to the corrosion resistance of the good soil, according to the Auger electron spectrometer AESuuger 61 _ 200907117 spectroscopy, AES) analysis shows that the general stainless steel wire only has a thin layer of chromium oxide film on the outer layer (see Annex 1) and it is easy to produce I basic in the process of stretching the wire. Defects, (see Annex II), and at the same time (4) the residual steel wire is easily scaie on the surface due to the high temperature of the extrusion of the eye mold during the process of stretching (the invention is based on the invention) The failure of the steel wire or the non-recorded steel wire due to the processing and degreasing cleaning is not completely caused by the shortcomings / progress - step by step, in order to use effective finished degreasing and electropolishing to the non-recorded steel wire or not The steel wire product is surface treated to improve its corrosion resistance and normal service life. The first object of the present invention is to electrolytically degrease the steel wire or stainless steel wire after being fabricated into the required finished product. of After degreasing treatment, after washing with water, the non-line or residual steel cable is polished = to correct the rough surface of the finished surface layer: ^ The anti-purity of the finished product of the product, followed by weak acid activation and water washing, for drying Stainless steel wire or non-scale steel cable has excellent corrosion resistance and increases the gloss of its surface. In addition to the second object of the present invention, 4 butyl μ A ^ 疋 is used for the electrolytic degreasing process of stainless steel wire or stainless steel wire. ~6〇g/L hydrogen The third object of the invention is to make non-recorded steel wire or stainless steel wire for 200907117. The main agent used for electrolytic polishing treatment is 4〇~6〇% phosphorous acid, and 20~40 % sulfuric acid. The fourth item # of the present invention is a main agent used for the weak acid activation process for the unrecorded steel wire or the unrecorded steel wire is 5 to 1% nitric acid. [Embodiment] The high-purity stainless steel wire designed by the present invention The structure and treatment method of the 'paragraphs' and 'two heads' are mainly for the smoothing of the rough surface of the stainless steel wire which is woven by the non-scale steel wire to achieve effective degreasing' and processing in the stainless steel wire. polishing The principle is that the stainless steel wire is firstly degreased by electrolysis (丨) to achieve complete degreasing treatment, then washed with water (2) to remove the degreasing agent, and then the stainless steel wire or stainless steel wire is electropolished (3) to the finished surface layer. The rough surface is precisely leveled to improve the corrosion resistance of the finished product, followed by weak acid activation (4) and water washing (5) for finished product drying (6) to make the stainless steel wire or stainless steel wire have better corrosion resistance. The traits and the luster of the surface are increased. Among them, the main agent used for the electrolytic degreasing process is stainless steel wire or stainless steel wire, which is 30~60g/L sodium hydroxide, and the stainless steel wire is twisted with stainless steel wire. The finished product of the required form and specifications is subjected to electrolytic polishing. (3) The procedure is to immerse the stainless steel wire in a phosphoric acid-based electrolyte (here, 4〇~60% phosphoric acid, and 20~40% sulfuric acid). The electrolyte is implemented), and is energized to transfer positive and negative ions to generate an electric field. 200907117 " Electrolytic polishing of stainless steel wire, when stainless steel wire is in operation* After the polishing process, 'Anodic polorization is used in 3.5% wt NaCl, and the apparent pitting potential of the surface is significantly increased. It is proved that the polished film is not easily pierced by the surface of the polished steel wire. For a more complete passivation film, the annual corrosion rate (mm/year) of the unrecorded steel wire can also be reduced from 0.07 (mm/year) before untreated to 〇· 〇3 (mm/year), so that the stainless steel cable is Under electropolishing, the corrosion resistance can be improved. At the same time, the electro-polished steel wire has a smoother and more complete degreasing process due to its surface, and has a brighter appearance on its exterior. In addition, the outer layer of the stainless steel wire in the polishing process has a high content of chromium and oxygen, and the oxygen content is lowered from 4% to the inner layer of the outer layer and finally maintained at 1%, which is known to be electrolytically polished. The process of the stainless steel wire has a thick chromium-rich and oxide film on its surface (refer to the AES element content diagram of the Annexe IV, and the thickness of the oxide film is inferred from the oxygen content. The thickness of the electropolished oxide film is more than five times that of the stainless steel wire which is currently not subjected to electrolytic polishing. In the SEM micrograph of the electrolytic polishing process of the stainless steel of the present invention, it is observed that the surface is flat and has no mechanical damage (ie, no rough surface) on the surface of 1 000X, thereby reducing corrosion. The resulting incentives and increased stress concentrations are generated by the addition of 2000907117 'speed failure. At the same time, the main agent used in the process of weak acid activation (4) for the non-line or non-line of the present invention is 5 to 10% by weight of nitric acid. The implementation of the electroless degreasing and electropolishing process for the design of the unconstrained steel wire or the non-recording cable has the following advantages: 1. Stress-free polishing: electrolytic polishing is mainly the result of the interaction of phosphate on the surface of the anode electrode process disk. The metal ions dissolved in the anode and the phosphoric acid in the polishing liquid form a phosphate having a small solubility, a large viscosity, and a small diffusion rate, and slowly accumulate near the anode. For the microstructure of the stainless steel cord, the current density of the mucosa at the bulge is higher, the dissolution rate is faster, and the uneven position of the mucosa changes with the flow of the mucosa, and the rough surface is gradually flattened to achieve the purpose of stress-free polishing. 2. Increased gloss: The surface roughness of the stainless steel wire after the electrolytic polishing process is better flattened, so that the refractive index of the surface of the stainless steel wire is definitely improved to improve the contour and gloss of the finished product. 3. Surface improvement: The work hardened layer and scratches on the surface of the stainless steel wire during the wire drawing process have been improved and disappeared by electrolytic polishing, so that the stainless steel wire can prolong its normal service life. 4. Corrosion resistance increases · · The surface pitting potential of stainless steel wire is obviously increased after electropolishing, and an oxygen-rich, chromium-rich and iron-depleted oxide film is formed on the surface, which can effectively improve the steel wire of 200907117. Use the rhythmic ability of the environment. The above-mentioned invention can effectively improve the durability and normal service life of the stainless steel wire or the non-recording steel wire in the process of fat and electrolytic polishing, and conforms to the implementation value of the available patents of the invention patents.
