The service life of the original galvanized iron welding mesh is very limited. Generally, good iron railings can only be used for about 2 years, and then renovated until the service life, which is not only time-consuming but also has safety risks. After the appearance of zinc-steel railings, the service life has been increased to a great extent in the post-processing. Generally, it can be used for at least 20 years. To improve the service life of zinc steel railings, we first have a brief understanding of the product characteristics of railings. Then from the maintenance aspect, it is necessary to maintain. Maintenance method of electric welding mesh:
- (2) Spray large number hook mesh guardrail should be used electric spray paint or electrostatic spray paint.
Post time: 14-10-22- Nemator roller cage is connected by nemator connecting clasp with longitudinal tension bar fixed on the support, and the connection between longitudinal tension bar and support is selected. The 2.5mm cold-drawn galvanized steel wire is wound 2 times and then tightened and fixed. The bracket is set on the column and the cross side of the protective fence with a span of 3m. Other spans are only set on the upper part of the column, and the bracket and the protective fence are connected with the bracket hoop.
- First of all, the protective layer of zinc-iron alloy can prevent the steel wire from being corroded by oxidation. The zinc metal reacts with water and oxygen to form a dense zinc oxide layer, which forms a physical barrier to prevent oxygen and water from entering the inside of the steel wire, reducing the chance of corrosion. Compared with ordinary steel wire, hot-dip galvanized wire is more resistant to corrosion in humid, high humidity or corrosive environments such as acid and alkali, so it is more durable.
- Galvanizing can be done by zincate galvanizing or chloride galvanizing. Appropriate additives shall be used to obtain a coating that meets the requirements of this standard. Luminescence treatment should be carried out after luminescence plating. The parts that need to be dehydrogenated for passivation should be passivated after dehydrogenation. Before passivation, 1%H2SO4 or 1% hydrochloric acid should be applied to activate 5~15s. Passivation shall be treated with colored chromate unless otherwise specified in the design drawings.
Even so, when they come out, they will uncover the mess, even though they know they will be punished, but only in a cage.) If you have time to refer to some foreign dog books, also strongly advocate cage training as a puppy. Before starting cage training, the cage is padded with a water bottle, some fun toys and bones to chew on. The cage door must be opened. Order the dog into the cage, then lure it into its new den with tasty cookies.
1. Principle. Because zinc does not change easily in dry air, and in humid air, the surface can form a very dense film of zinc carbonate, which can effectively protect the interior from corrosion. And when the coating is damaged for some reason and the matrix is not too large, the zinc and steel matrix form a micro cell, so that the fastener matrix becomes the cathode and is protected. It is widely used in automobile transportation and other industries, but what is needed is the trivalent chromium passivation layer, zinc nickel alloy plating closed coating, reduce the harmful and toxic layer of hexavalent chromium passivation.

Post time: 07-02-23“Dry” hot dip galvanizing is also called “drying solvent method” hot dip galvanizing. Iron and steel work pieces through degreasing, pickling, cleaning, dipping aid solvent and drying, and then immersed in the molten zinc solution to galvanize. The co-solvent is usually hydrochloric acid, ammonium chloride, or ammonium chloride mixed with zinc chloride in aqueous solution.
- Although the chemical formula is conducive to a high deposition rate, the coating thickness cannot meet the requirements after the organic matter is loaded, so activated carbon can be used to treat the tank. Zinc is a silver-white metal, brittle at room temperature, soluble in acid and alkali, known as amphoteric metal. Pure zinc is more stable in dry air. In humid air or small water containing carbon dioxide and oxygen, the surface of large rolls of galvanized wire will generate a layer of basic zinc carbonate based thin film layer, which can delay the corrosion rate of zinc layer.
Large hexagonal net called the stone cage net. Stone cage net before delivery, must be folded into a simple surface, packed compression after delivery. Then put it into the right position to open, and then put the appropriate size of the stone into the cage, the lid tight, and then the various stone cage net and adjacent stone cage net tied up.
The strength of the hook mesh should be satisfied: when the vehicle is traveling at 80 kilometers per hour, the hook mesh will not fall into the river when it bumps against the rail at a 15 degree Angle. The shape and color of the hook mesh should be in harmony with the surrounding natural environment. The phenomenon planning of the important Bridges should be done well. When the bridge crosses important traffic lines, such as expressways, urban rail transit, expressways, railway trunk lines, etc., the hook mesh should add the protective mesh on the pavement of the bridge deck.
Welding mesh is widely used in industry, agriculture, breeding, construction, transportation, mining and other aspects. Such as machine shields, animal fences, flower fences, window fences, access fences, poultry cages, egg baskets and home office food baskets, paper baskets and decorative. We can make it according to the special requirements of customers. Welding mesh is made of high quality low carbon steel wire row welding, and then cold plating (electroplating), hot plating, PVC plastic coated surface passivation, plasticizing treatment, smooth mesh, uniform mesh, solid solder joint, local machining stable performance, corrosion resistance, corrosion resistance. Features: Stainless steel mesh selection of high quality stainless steel wire row welding, more acid, alkali resistance, solid welding, beautiful, widely used and so on.
- 1) wire thickness: we also know that the pet cage wire is too thin to be easily bitten off by dogs, the general cage wire on the market are 3mm steel wire, such wire is only suitable for small dogs or rabbits, for large dog friends I suggest to buy more than 4mm thick.
- Most builders buy hot-dip galvanized wire. They want good corrosion resistance. And people use galvanized wire products in their daily life, such as wire mesh guardrail, galvanized wire is more, which still takes into account the cost. In addition, galvanized silk will also be used in the field of art. Artists are attracted to its bright color and softness, so the factory must consider these factors when producing galvanized silk.
Now the pet cage on the market is still mainly wire cage, so the identification of wire cage mainly has the following parameters:
As a very important product of the barbed rope factory blade barbed rope can be said to have made a great contribution, but often due to the opaque processing process often do not get the trust of customers.
Post time: 24-02-23Compared with the traditional barbed and twisted barbed rope, the raw material cost is relatively high because of the relatively complex process.
When large rolls of galvanized wire are used to bind and reinforce the goods, corresponding binding methods should be selected according to the fastening node conditions of the strengthened goods, such as opening binding, opening binding, insertion binding and so on. The insulation layer of semi-hard and soft insulation products shall be based on the diameter of the steel pipe and the size of the equipment. Large rolls of galvanized wire or glue are tied together with a width of 60mm. The binding interval of semi-hard insulating products shall not exceed 300 mm; The larger length of felt and cushion shall not exceed 200mm, and the number of belts shall not be less than 2.
- The smaller the mesh of decorative hook mesh, the finer the demand wire, the larger the mesh, the thicker the demand wire. For example, 6.5cm mesh aperture, the required iron diameter is 3.5mm-4mm. Then a fine welding will be broken, and then thick and heavy, workers can not bear.
- 3. Gently rub soapy water on its body and scrub gently with a towel. Make sure you don’t get anything in his eyes or it might scare him into attacking you (he might show his little fangs and claws).
Large roll galvanized wire can be divided into hot-dip galvanized wire and cold galvanized wire, the difference between the two lies in the way of zinc and the amount of zinc. Hot dip galvanizing is to soak steel wire in melted zinc liquid, hot dip galvanizing zinc fast, zinc layer thick rust prevention performance is very good, but the zinc is not uniform, and the surface is dark, the life of hot dip galvanizing can reach 20 years.

Post time: 24-04-22The impregnated hexagonal wire mesh will lose its original characteristics after corrosion, and will change in shape, color and mechanical properties, resulting in equipment damage, pipeline leakage, etc., specifically, it is easy to break and lose the original protection function. Usually there are three kinds of metal corrosion: physical corrosion, chemical corrosion, electrochemical corrosion, corrosion in addition to the chemical properties and organizational structure of the metal itself, but also related to the surrounding medium, such as wet environment than dry environment easy corrosion, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the corrosion of impregnated hexagonal wire mesh, prolong the service life of products.
- Similar to two materials in the coating part melting together, and coating thickness can reach 100 microns, so high corrosion resistance, salt spray test 96h no problem, equivalent to 10 years under the usual environment; Cold galvanizing is electroplating at room temperature. Although the thickness of the coating can also be controlled, the binding strength and thickness of the coating are relatively low, so the corrosion resistance is poor.
- Atmospheric relative humidity At the same temperature, the percentage of atmospheric water vapor content and its vapor saturation content is called relative humidity. Below a certain relative humidity, the corrosion rate of metal antirust oil is small, while above this relative humidity, the corrosion rate increases sharply.
Galvanized wire is divided into hot dip galvanized iron wire and galvanized iron wire according to the production process. It has the characteristics of high tensile strength, good softness, zinc layer uniformity, corrosion resistance, beautiful color, good smoothness, strong adhesion and corrosion resistance. Hot dip galvanizing has better protective properties than electric galvanizing, so it is an important protective coating for steel parts used in harsh working conditions.
The production process of large coil galvanized wire is relatively simple. The wire after cleaning is put into electroplating solution first. Of course, the plating solution should contain zinc oxide, a direct current of steel, another zinc plate in the plating solution. The zinc is transferred to the surface of the steel as a molecule. If it shows a bright and beautiful color, the wire is coated with zinc.
Stainless steel barbed wire in the way of corrosion is not too, because the surface is not treated but rely on its own raw materials for corrosion resistance, so there will be no chemical reaction.
The life of the “wire”, is actually “low carbon steel wire”, carbon content in less than 0.2%. The surface is usually coated with zinc plating because it is easy to rust. Under atmospheric conditions, the galvanized layer will not rust before most of the fall off, relatively soft. The life of the “steel wire”, is carbon content in about 0.6% of the “carbon steel wire”, or carbon content in about 0.8% of the “high carbon steel wire”, they have enough hardness and elasticity after appropriate heat treatment, high strength. Uses such as winding ordinary spring and so on.
