Use of galvanized iron wire
Matters needing attention for pickling
General hardware and machinery factories produce iron wire, or galvanized iron wire is used to produce galvanized iron wire according to customer requirements. The difference between galvanized iron wire and general wire is very large. Generally, the wire is cheap, and because the iron is not very stable, it is easy to rust in a humid place, so the stability is not very good, and the life is not very long; the galvanized iron wire is plated on the outside of the wire. A layer of stable zinc, with a layer of zinc to protect the wire, so that the wire life is longer. Therefore, the machinery factory must learn to use galvanized iron wire.Our company galvanized wire price is lower,And it's of good quality.
A very important step before galvanizing iron wire is to pickle the iron. Pickling is to wash away some oxides on the iron surface with some acid mist or acid, that is, rust, and some other corrosive substances. To achieve the purpose of cleaning iron, zinc will fall off when galvanizing. Pay attention when pickling. The acid is very corrosive. Therefore, when adding acid, you must pour the acid into the water, and it is along the cylinder wall. Do not pour it at once to avoid splashing.
Remember to order the acid, acid into the water instead of water into the acid, water into the acid will cause splashing and boiling, be sure to bring protective glasses when pouring acid, be sure to ensure that there are no non-professionals on the side, so as not to cause some Risk of splashing acid.
About galvanized wire:
Type: the electric galvanized wire is also called cold galvanized wire.
Process flow: high-quality iron wire, pickling and rust removal, three times washing, dehydration, five times galvanized, three times washing, dehydration, light out, washing, dehydration, drying, wire collection, packaging.
1. Mesh: square eye mesh (flat weaving), electric welding mesh, hexagonal mesh (twisting), ginning mesh, mat mesh, metal steel mesh, guardrail mesh, conveyor belt mesh, hook mesh, sound network, and other industries;
2. Drawing: wire drawing, cleaning ball silk, process silk, weaving mesh silk, etc.;
3. Arts and crafts: chain, plastic bag, paper bag, lacquer bag, and various arts and crafts;
4. Pulp bag silk: pear bag, grape bag, apple bag, mango bag, loquat bag, peach bag, pomegranate bag, orange bag, orange bag, lemon bag, etc.
5. Other USES: drawing, flattening, cutting, splice, wire, communication, wire fastening, binding, etc.
Because galvanizing silk commodity has the characteristic such as beautiful surface, corrosion-resistant property, its use scale is more and more extensive.
Features: good flexibility, high zinc content, good brightness, corrosion resistance, no zinc removal.
Galvanized wire features: galvanized wire has good toughness and elasticity, the maximum amount of zinc can reach 300 grams/square meters. With thick galvanized layer, corrosion resistance, and other characteristics.
Application of galvanized wire: the products are widely used in construction, handicraft, weaving screen, highway guardrail, product packaging and daily civil and other fields.
Galvanized wire is made of high-quality low carbon steel wire rod processing galvanized wire products. Galvanized wire is divided into hot galvanized wire and electric galvanized wire two. Galvanized wire production process: the use of high-quality low carbon steel after drawing molding, pickling rust removal, high-temperature annealing, hot galvanized, cooling and other processes.
The production process of general galvanizing wire is coil -- big draw -- annealing -- middle draw --annealing -- galvanizing.
Galvanized wire features: galvanized iron wire has good toughness and elasticity, the maximum amount of zinc can reach 300 grams/square meters, with galvanized layer thickness, strong corrosion resistance and other characteristics.
Calculation of tensile strength of galvanized wire:
Cross-sectional area of steel wire = square diameter *0.7854mm2 wire breaking tension Newton (N)/cross sectional area mm2= strength MPa
The above is our common sense of galvanized wire to make a detailed introduction, I hope to help you.
