- The effect of chemical composition and metallographic structure of steel wire
Post time: 20-09-22The 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.
Post time: 11-06-24Hot dip galvanizing is then oiled and chromed. The quality of hot-galvanized sheet produced by this method is significantly improved compared with that by wet galvanizing method. It is only valuable for small-scale production. Continuous galvanizing production line includes a series of pretreatment procedures, such as alkali degreasing, hydrochloric acid pickling, water washing, solvent coating, drying, etc., and the original plate needs to be annealed in cover furnace before entering the galvanizing line.
The quality of hot-dip galvanized barbed wire is only good in the surface of the wire attached to the galvanized layer, and with the chemical reaction, the surface of the zinc layer will gradually lose effect because of the oxidation reaction, this situation is more prominent in the humid area of the environment. And because after all, it is rusty iron wire, so the quality of hot-dip galvanized barbed rope is certainly not up to the level of stainless steel barbed rope.
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.
- The production and processing process of blade barbed rope is tedious, which requires the cooperation of all departments, and the production cycle is relatively long. The barbed rope, whether galvanized barbed rope or stainless steel barbed rope, due to the relatively simple structure, the degree of mechanization in the production process is relatively high, so this is also a big difference in the price.
Cooling can be in the groove close row of thin wall plastic pipe, through the flow of tap water for cooling, can also be used as a temperature control device titanium pipe. In the process of electroplating galvanized wire, it is necessary to stir the plating solution to obtain the composite coating with particles dispersing in the matrix metal. Stirring methods include mechanical stirring, air stirring, ultrasonic stirring, bath circulation, etc.
After annealing, the wire will become soft, flexibility will increase, iron is a relatively active metal, and more active than hydrogen, so it is a good reducing agent. At room temperature, iron is not easy to react with oxygen, sulfur, chlorine and other non-metallic elements in dry air. Its production cost is lower, its use and scale are also relatively wide, and it has better protective function. Therefore, it is an important material for steel parts in strict working environment.
- Choose a cage with a proper structure, such as a tray under the cage so that the dog can urinate in the cage. It’s also easy for the owner to clean up.
Post time: 12-05-23- In addition, many luxury cat cage, dog cage, parrot cage, bird cage and flock bird cage, will use iron square tube. Luxury cage using iron square tube is generally as a cage body frame, and then on each side of the welded iron wire. Square tube cage is characterized by more beautiful shape design, cage body more solid, more surface treatment methods.
- 1. Put the cat carefully in the special basin for washing the cat. Keep your cat as calm as possible.
- The mixture of rare earth and aluminum enhances the fluidity of zinc liquid, makes the coating more uniform, and also reduces the zinc consumption. Hot dip galvanized wire has better protection performance than cold galvanized wire, which makes it good application in chemical experimental equipment. Hot dip wire coating thicker, so that it has good corrosion resistance, can be in the outdoor sun and rain and other harsh environment can be maintained for decades, so hot dip galvanized wire is widely used in construction, traffic guardrail and other outdoor facilities.

Post time: 02-09-22- The middle of the two thorns is 7 to 8 circles, while the ordinary thorn rope is only 3 and a half circles, showing neat and beautiful.
Some customers are just for ordinary fencing, but the pictures provided to the barbed rope factory are indeed applied to the barbed rope products in prison, maybe because the customers prefer the style, but such products are really a little overqualified to be installed in ordinary areas. Even if the customers prefer such barbed rope products, the higher price is prohibitive. The price and quality of the prison rope are certainly not the level of the rope we contact in our daily life.
- The difference between 304 and 201 stainless steel wire rolling cage is the difference in material, material determines the price, so the price of 304 stainless steel blade gill net is slightly higher, the following mainly to explain the difference in two raw materials.
- Again: positive and negative twisting barbed rope appearance beautiful
2. Eliminate the caked zinc residue at the zinc liquid surface
- The first difference is in the amount of zinc.

Post time: 26-07-22Products are widely used in construction, handicrafts, wire mesh, highway guardrail, product packaging and daily civilian and other fields. Galvanized wire is divided into hot galvanizing, cold galvanizing, electric galvanizing, hot galvanizing price is high, the price of electric galvanizing is low. Hot dip galvanizing is not easy to rust, electric galvanizing is easy to rust, this is a simple discrimination. Hot dip galvanizing is dipped in zinc liquid melted by heating, with fast production speed and thick but uneven coating. The market allows a low thickness of 45 microns and a high of more than 300 microns.
Because of the high carbon content, simple cracks occur during water quenching, so double liquid quenching (water quenching + oil cooling) is mostly used, and oil quenching is mostly used for small cross section parts. This type of steel is generally used after quenching by medium temperature tempering or normalizing or in the surface quenching state. Mainly used for manufacturing spring and wear-resistant parts.
There is as far as possible not to show the trace of the application of wire, wire wound flower stems should be wrapped with green or brown tape, in order to cover the trace of the use of wire, in the use of wire modeling can make the drooping flower head raised, and the flower head reinforcement, for herbs and other flower material soft plants, can make the stalk straight. Wire shearing method: if you want to cut the wire, the wire should be straightened and then cut, can not bend the wire, fold and then cut, otherwise, the wire cut is not straight, will bring a small hook, affect the use.
Post time: 30-06-22- Electric welding net is also known as external wall insulation wire mesh, galvanized wire, galvanized electric welding net, wire mesh, row welding net, touch welding net, construction net, external wall insulation net, decorative net, wire mesh, square eye mesh, screen mesh, anti-crack mesh. Stainless steel electric welding mesh, is made of high quality stainless steel wire row welding, more acid resistance, alkali resistance, welding firm, beautiful, widely used and so on.
- The most obvious gap in a short time is the cross section. Because the hot-dip galvanized barbed rope is surface anticorrosive treatment, there will be rust in the cross section, while the stainless steel barbed rope because the internal raw materials are consistent with the surface raw materials, so there is no such situation.
Post time: 23-12-22- In addition, galvanized silk manufacturers can be required to passivation treatment after zinc immersion, after passivation treatment of zinc has a better anti-discoloration effect, can effectively extend the time of discoloration, the combination of the two, discoloration should be able to solve.
The characteristics of hexagonal wire mesh: strong structure, flat surface, with good corrosion resistance, oxidation resistance and so on.
