  • A remarkable characteristic of stainless steel wire rope is its inherent corrosion resistance to concentrated nitric acid and dilute nitric acid, which makes it easy to be distinguished from most other metals or alloys. But high carbon 420 and 440 steel in the nitric acid point test is slightly corroded, non-ferrous metal encountered concentrated nitric acid is immediately corroded, and dilute nitric acid has strong corrosion on carbon steel.

  • Although the chemical formula is conducive to a high deposition rate, the coating thickness cannot meet the requirements after the organic matter is loaded, so activated carbon can be used to treat the tank. Zinc is a silver-white metal, brittle at room temperature, soluble in acid and alkali, known as amphoteric metal. Pure zinc is more stable in dry air. In humid air or small water containing carbon dioxide and oxygen, the surface of large rolls of galvanized wire will generate a layer of basic zinc carbonate based thin film layer, which can delay the corrosion rate of zinc layer.

  • Take 20cm galvanized wire for acid fog experiment, check the zinc content of galvanized wire through the balance to see whether it meets the zinc layer standard required by the customer, ensure that the metal wire can achieve the role of rust and corrosion prevention, and meet the service life required by the customer. Galvanized iron wires must be packed in good condition, bound neatly and orderly, and bound with an inward end to prevent scratches during transportation. The inspection standard of galvanized iron wire also includes the tensile test. This item is determined according to the material of the galvanized wire order ordered by the customer, and it needs to be tested by comparing the raw material list.
