Stainless steel materials refer to steels resistant to weak corrosive media such as air, steam, water, and chemically corrosive media such as acids, alkalis, and salts, also known as stainless acid-resistant steel. In practical applications, the steel resistant to weak corrosion medium is often called stainless steel, and the steel resistant to chemical medium corrosion is called acid-resistant steel. The galvanized wire has good toughness and elasticity, and the amount of zinc can reach 300 grams per square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Products are widely used in various fields such as construction, handicrafts, weaving wire mesh, highway guardrails, product packaging and daily civilian use.
Large coil galvanized wire is divided into hot-dip galvanized wire and cold-dip galvanized wire. Hot-dip galvanized wire is darker in color and consumes more zinc metal. It forms an infiltrated layer with the base metal and has good corrosion resistance. Hot-dip galvanized wire can maintain several ten years. The production speed of cold galvanizing is slow, the coating is uniform, the thickness is relatively thin, usually only 3-15 microns, the appearance is bright, and the corrosion resistance is poor. Generally, it will rust in a few months.
Stainless steel wire drawing is a metal processing (stainless steel) process. It is a popular surface treatment technology in the stainless steel and aluminum product industry. It is a wire drawing effect treatment for stainless steel and aluminum products. So galvanized wire and stainless steel wire are two different products. Defects such as surface film layer and surface inclusions can be found and treated by conventional techniques in order to locally remove the surface film layer and surface inclusions on the outer surface of the deposited layer for galvanized iron wire. Excessive suds are caused by the entrainment of soap and saponifiable fat surfactants into the bath.
Moderate rates of foam formation are probably harmless. The small homogeneous particles of large denier in the bath can stabilize the foam layer, but the accumulation of too many solid particles will cause an explosion. Removal of surfactant by matting with activated carbon or destabilization of the foam by filtration are effective measures; other measures should also be taken to minimize carryover of surfactant.
In general, the introduction of organic matter contained in galvanized wire can significantly reduce the plating speed. Although the chemical formula is conducive to a high deposition rate, the thickness of the coating cannot meet the requirements after the organic matter is brought in, so activated carbon can be used to treat the bath. Zinc is a silver-white metal, brittle at room temperature, easily soluble in acid and alkali, and is called amphoteric metal.
