Post time: 05-01-23 3. Scope of application. Electrogalvanizing involves more and more extensive fields, fastener products have been widely used in machinery manufacturing, electronics, precision instruments, chemical industry, transportation, aerospace and so on in the national economy is of great significance. Packing and binding galvanized wire is in the liquid state of zinc, after a messy physical and chemical effect, not only on the steel plated thick pure zinc layer, and also generate a zinc-iron alloy layer. This plating method, not only has the characteristics of corrosion resistance of galvanized wire, and because of the zinc iron alloy layer. It also has strong corrosion resistance that can not be compared with electric galvanizing. Therefore, this plating method is particularly suitable for a variety of strong acid, alkali fog and other strong corrosive environment.

Stainless steel is short for rust acid steel, air, steam, water and other weak corrosion medium or stainless steel is called stainless steel; And the chemical corrosion resistance medium (acid, alkali, salt and other chemical etching) corrosion of steel called acid steel.
Because of the pre-tension given to the packaging and binding of galvanized wire, it has the excellent characteristics of low relaxation value, small stress loss, good stability after loading, not easy to deformation, no fracture, strong elasticity, ordinary steel lines and rebar are difficult to compare. The use of advanced galvanized finishing process, therefore, the use of hot-dip galvanized steel wire construction, not only good corrosion resistance, but also beautiful and generous. The product has the characteristics of smooth surface, high dimensional accuracy, good uniformity of zinc layer and strong adhesion.
The application range of small hexagonal mesh is also relatively wide, can be used for building wall fixed insulation layer, pipeline, boiler fixed heat preservation, decoration and other fields.
2. Stainless steel 316 material should be used in coastal areas, which can resist corrosion of sea water.
Annealing wire is widely used mainly because it has a good elasticity and flexibility, in the annealing process can be a good control of its hardness and softness, it is mainly made of iron wire, more commonly used in the construction industry tie wire use. So why annealing wire according to material properties processing?
Post time: 14-09-22 Galvanized wire hexagonal mesh material: cold galvanized wire, hot galvanized wire, to draw wire
Environmental factors should be considered when choosing the thickness of galvanized layer. Galvanized wire in galvanized, pay attention to the above problems, can be well galvanized, to ensure the quality of galvanized wire. Galvanized methods are mainly divided into two types, one is hot dip galvanizing method, the other is electric galvanizing method. This paper mainly introduces the method of galvanizing. Electrogalvanizing is an electrolyte used for galvanizing.
Low and medium carbon steel wire is used as raw material, with good surface gloss, uniform zinc layer, strong adhesion, corrosion resistance and so on. Available: diameter 1.60mm-4mm (16#-33#) cold plating wire; Diameter 6.40mm-0.81mm(8#-21#) black iron wire, changed wire. It is mainly used in communication equipment, medical equipment, weaving net, brush, steel cable, filter, high-pressure pipe, construction, crafts and other industries.
As we all know, the use of hexagonal net protection, can protect the natural environment while protecting the bridge, so as not only to green the ecological environment, but also to prevent soil erosion.
The use of packaging galvanized wire with the development of industry and agriculture is also expanded accordingly. Therefore, galvanized silk commodities have been widely used in industry (such as chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transportation, shipbuilding, etc.), agriculture (such as irrigation, heating houses), construction (such as water and gas transportation, wire casing, scaffolding, houses, etc.), Bridges, transportation, etc., in recent years. Because galvanized silk products have beautiful surface, good corrosion resistance and other characteristics, its use is more and more extensive.
The application range of positive and negative twisted barbed wire is also very wide. It is a good choice for purchasing barbed wire. So what are the advantages of positive and negative twisted barbed wire compared with other barbed wires? The following barbed wire factory will introduce the positive and negative twisted wire in detail. Three advantages of rope
If adult dogs and puppies touch noses out of love for the dog, then adult dog nose touch is more meaningful. For example, dogs can touch their noses to communicate where food is safe and whether people or other animals are in danger.Aliases: Gabion mesh, heavy hexagonal mesh, ecological mesh, wire mesh, etc.
So, do you know how to pick the right dog cage? When choosing a dog cage, focus on quality and practicality! Let’s take a look at it:
1. After getting the bird cage, do not rush to use it. Clean the cage with a clean cloth or rubber. Then use fine yarn paper (do not use coarse sandpaper randomly), gently polish some parts that need to be polished again to improve the surface finish and trace, and pay attention to not damage the original bamboo green. After careful observation, use a razor blade to carefully clean the individual areas with small burrs.
Large roll galvanized wire is processed from high quality low carbon steel wire rod. Each wire rod rolled by continuous rolling mill is not less than 200kg, but 15% of the number of plates in each batch is allowed to be composed of two, of which the weight of each rod is not less than 80kg, and 4% of the number of plates in each batch is allowed, and the mass of its single wire rod is less than 200kg, but not less than 40kg. Each rod rolled by semicontinuous mill shall not be less than 60kg, and each batch shall be allowed to have 5% disk nitrogen. The mass of the rod shall not be less than 60kg, but not less than 30kg.
Poor pretreatment before plating; Bath temperature is too low; Poor quality of additives or too many additives and organic impurities will cause poor bonding. The quality of additives also has an effect on coating foaming. Some additives react incompletely during synthesis and continue to polymerize during long-term storage or use. The additive tends to distort the crystal lattice and cause stress, causing the coating to bubble.
Pay attention to safety in line collection and operation, others without the consent of the monitor, Ben have to get on the bus operation. The reels should be placed lightly, stacked firmly and neatly, not more than 5 reels. Direct contact with acid and alkali must be prohibited. When the acid fog exceeds the specified target of the state, measures should be taken to control it in time, otherwise production is not allowed.
