Large rolls of galvanized silk play a very important role in our life. Made of low carbon steel rod processing, after drawing forming, pickling rust removal, high temperature annealing, hot dip galvanized. Cooling and other process processes. Galvanized wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire). Galvanized iron wire has good toughness and elasticity, the amount of zinc can reach 300 g/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance.
Specific requirements for the safety of galvanized wire production: clean up all tools and other objects that hinder production in the galvanized wire production environment. Operators in the pickling process, pay attention to the action should be careful, not careless, into the pickling tank must be handled lightly, to prevent splashing on the body. When adding acid, the acid must be slowly poured into the water. It is forbidden to pour the water into the acid, so as to prevent the acid from splashing out and hurting people. Do not hurt yourself or others.
If the zinc coating is good, but in 3% nitric acid when the light, the coating has dark shadow, passivation occurs when the film is brown, may be caused by foreign metal impurities such as copper or lead in the galvanizing liquid. When problems occur in the process of galvanizing large coil galvanized wire, the temperature and current density are checked first, and then the content of zinc and sodium hydroxide in the plating solution is measured and adjusted through the analysis of the plating solution. Whether DPE content is low can be determined by hull cell test.
Generally speaking, in dry main gas and indoor use, the thickness of galvanized coating is only 6-12μm, but under poor environmental conditions, the thickness of galvanized coating is 20μm, can reach 50μm. Therefore, environmental factors should be considered when choosing the thickness of galvanized layer. Galvanized layer after passivation treatment, can naturally form a layer of bright, beautiful color passivation film, can obviously improve its protective function, decorative.
Purpose of galvanized hexagonal net: building wall fixed, heat preservation, heat insulation; Power plant tied pipe, boiler warm; Anti-freezing, residential protection, landscaping protection; Raising chickens and ducks, isolating chicken and duck houses, to protect poultry; To protect and support seawalls, hillsides, roads and Bridges and other waterworks.
Wire mesh even in the mining industry also has a higher reflection, because the selection of low-carbon materials to do the material so that it has a general iron net class does not have flexibility, concluded that its plasticity in use, and then can be used in hardware crafts deep processing production, as the wall plastering, leak prevention crack and so on. Its light net body, lower cost, more can let customers experience its economic benefits.
Construction welding net work wall insulation project using galvanized welding network in wall insulation and rust engineering project plays a necessary role, wall painting batch putty network is divided into two kinds: this is galvanized welding network; Another is to change the wire drawing wire welding mesh, according to the provisions of the region, construction enterprises to carry out effective material selection. Construction welded wire mesh new mink cage new mink cage grommet see more 1 inch, from silk in 2 mm up and down, management method is simple and easy, a mesh surface bright and clean and is not easy to scratch mink, galvanized welded wire online zinc quantity proportion, it is not easy to rust, new mink cage up more convenient, mink settled in natural environment more comfortable, the price also is higher than before the same specifications of the mink cage competitive many, But the overall character is not harmed at all, it is stronger.
Because the coating obtained is thicker, hot-dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for steel parts used in harsh working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transmission, shipbuilding and other industries, in the agricultural field such as pesticide irrigation, greenhouse and construction industry such as water and gas transmission, wire casing, scaffolding, Bridges, highway guardrail and other aspects, has been widely used.
