The main factors causing metal rust: relative humidity of the atmosphere at the same temperature, the percentage of water vapor content and water vapor saturation content in the atmosphere, known as relative humidity. Under certain relative humidity, the corrosion rate of metal antirust oil is very small, but higher than the relative humidity, the corrosion rate increases suddenly. This relative humidity is called the critical humidity. When the humidity in the atmosphere is higher than the critical humidity, the metal surface will appear water film or water droplets, if the atmosphere contains harmful impurities, dissolved in the water film, water droplets, electrolytes and aggravate corrosion.
In the electroplating tank through the current unidirectional make zinc plating on the metal surface gradually, the production speed is slow, the coating is uniform, the thickness is thin, usually only 3-15 micron, the appearance is bright, smooth, beautiful, poor corrosion resistance, generally will rust in a few months. The production process of hot wire plating mainly includes: preparation of the original plate → pre-plating treatment → hot dip plating → post-plating treatment → finished product inspection, etc. According to custom often according to plating pretreatment method.
- Suitable for general engineering building wall, pouring concrete, multi-storey building, etc., in the structure of heat preservation and heat insulation system plays an important role, when the construction will be hot dip galvanized welded wire rack together wall of heat preservation and heat insulation board placement will be concrete pouring mold inside, outside the wall heat preservation and heat insulation board and one kind of live, after ripping into heat preservation and heat insulation board and wall body. The coating on the surface of the welding core is called the coating.
Galvanized wire mesh is divided into hot dip galvanized wire mesh and cold galvanized wire mesh. Galvanized steel wire net selects the high quality low carbon steel wire, iron wire factory made by precision of automation machinery welding technology processing, smooth surface, firm structure, integrity is strong, even if the local cutting of galvanized steel wire net, or local also under pressure from loose phenomenon, after molding, wire mesh galvanized corrosion resistance good, has the advantage that the general steel mesh does not have.
- 5. It prevents your dog’s fear from causing chaos or other problems.
Barbed wire even in the mining industry also has a higher embodiment, because the selection of low-carbon materials to make it has a general iron mesh does not have the flexibility, determined its plasticity in the use, and then can be used in hardware crafts in the deep processing production, as the wall plastering, inside leak prevention crack and so on. Its light net body, the lower cost, can let the customer realize its economic benefits.
As we all know, even if it is the same kind of steel wire, because of the steel making process, wire drawing process and equipment are not the same, so the quality of steel wire production is not the same. Due to the different mechanical properties of steel wire itself, flattening process and equipment, the width and elongation of steel wire in the flattening process have different effects. Therefore, in the selection of wire diameter, the following three factors should be considered:
- Choose a well-structured crate, such as one with a tray under it so the dog can pee and defecate in it. It’s also easy for the host to clean up.
The application of cold wire drawing is very wide today. What problems need to be paid attention to in the acceptance of cold wire drawing in galvanizing plant?
Post time: 29-09-22The production process of stainless steel blade and galvanized blade is basically similar. The blade size is usually determined according to the mold.
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.
Post time: 08-05-23We can complete the installation of ordinary double-strand barbed rope by using wood shaft or even trees, but the blade barbed rope has high requirements for construction.

In the process of composite plating, it is necessary to stir the plating solution to obtain the composite coating in which the particles dispersed in the matrix metal. Stirring methods include mechanical stirring, air stirring, ultrasonic stirring, bath circulation, etc. In the process of production, the acid activation solution can remove the corrosion products and oxide film on the surface of low carbon steel wire without excessive corrosion on the matrix. Galvanized wire can be used zincate galvanized or chloride galvanized and other processes, appropriate additives should be used to obtain the coating required by the standards of low carbon steel wire.
Post time: 30-08-22- Hexagonal net weaving methods: positive twist, reverse twist, two-way twisting, first editing after plating, first plating after editing, and then divided into hot dip galvanized hexagonal net, electric galvanized hexagonal net, PVC plastic coated hexagonal net, stainless steel hexagonal net, etc.
In the atmosphere containing carbon dioxide and hydrogen sulfide and Marine atmosphere is not corrosion resistant, in high temperature and high humidity air and contain organic acid atmosphere is small, galvanized layer is also easy to be corroded. In order to make large rolls of galvanized wire on the surface of the deposited layer to the local, remove the surface film layer, surface inclusions and other defects can be found and treated by conventional techniques. Excess foam is caused by soaps and surfactant saponable fats brought into the tank, and moderate rates of foam formation may be harmless.
- 3, galvanized silk mesh binder transport, storage and use should be in accordance with the relevant provisions to adopt safety, fire prevention methods, so as to be more safe use.
Since the reform and opening up, China has stopped a series of reforms and explorations on the grassland pasture use and animal husbandry operation system in grassland pastoral areas. In the 1980s, the grassland contract system was introduced in Inner Mongolia and other regions, under which grasslands were collectively used and farmers contracted to operate them separately. Stainless steel barbed wire fence is widely used by herdsmen in grassland pastoral areas
Now the pet cage on the market is still mainly wire cage, so the identification of wire cage mainly has the following parameters:
- Reverse twisting of the barbed rope: first wrap the barbed wire around the main wire (that is, a single piece of iron wire) and then add an iron wire and twist together to form a double strand of barbed rope.
