Strictly control the pH value of large roll galvanized wire bath, research shows that the size of the bath pH value directly affects the quality of steel wire coating, improper control of pH value will cause loose coating. When the pH value is greater than 3, the steel wire coating has burr caused by fine dendrites, and the surface is not smooth. The current density is strictly controlled. From the microscopic morphology, the higher the current density, the larger the zinc layer grain deposition, the less dense the corresponding zinc layer.

Welding mesh is also known as external wall insulation wire mesh, galvanized wire mesh, galvanized welding mesh, wire mesh, row welding mesh, touch welding mesh, construction mesh, external wall insulation mesh, decorative mesh, barbed wire, square eye mesh, screen mesh, anti-crack mesh. Stainless steel welding net, is made of high quality stainless steel wire row welding, more acid resistance, alkali resistance, solid welding, beautiful, wide use and so on.

Out-of-line annealing means that the recrystallization annealing of hot or cold rolled steel plate is carried out in the bottom type annealing furnace or cover type annealing furnace before entering the hot plating wire line, so that there is no annealing process in the galvanized line. The steel plate must maintain a clean active surface of pure iron, free of oxides and other dirt, before hot dip galvanizing. In this method, the annealed surface oxide sheet is first removed by pickling method, and then coated with a layer of zinc chloride or a mixture of ammonium chloride and zinc chloride solvent for protection, so as to prevent the plate from being oxidized again.

You can also buy a cage from other places. You can choose the cage you like or find suitable on the website. For example, a pet store, supermarket, pet products website, etc., it is recommended that you buy metal cage, with a metal tray underneath, of course can also be of stainless steel and plastic, is plastic easily damaged by the dog bite, plastic tray is easy to be a dog of uric acid corrosion, but also show the low end of the plastic products, beautiful, durable.

The different spacing of the thorn rope is mainly in order to save costs to consider, because if they are too close, then obviously a little waste of resources, but the installation is too sparse will not work. Usually the bottom spacing is about 10cm, and the top is up to 20cm, this is because the higher the place is more difficult to climb over, usually more than one meter without the help of tools it is difficult for ordinary people to climb over, and the bottom because of the relatively tight can prevent personnel from drilling in the past.

When the zinc layer is seriously damaged and endangers the iron matrix, the zinc will produce electrochemical protection on the matrix, the standard potential of zinc is -0.76V and the standard potential of iron is -0.44V. When zinc and iron form microbatteries, the zinc will be dissolved as the anode, and the iron will be protected as the cathode. Obviously, the atmospheric corrosion resistance of hot dip galvanizing is better than that of electric galvanizing.

The physical methods mainly include manual rust removal and mechanical rust removal, chemical rust removal is generally the use of pickling method, practical application, usually according to the appearance of the workpiece rust status and different post-treatment process, choose different rust removal methods, among which pickling rust cleaning is more commonly used. That is, the iron and steel workpiece with oxide skin or rust is etched in the acid lotion, mainly to remove the oxide or rust layer on the surface of the steel.

Many electrogalvanized wire diameter products are formed by wire drawing, wire drawing is a kind of processing technology, can make the product reach the required shape and meet the standard mechanical properties. Cold wire drawing is carried out at recrystallization temperature, hot wire drawing is carried out at crystallization temperature, warm wire drawing is drawn at higher than room temperature and lower than crystallization temperature. Cold drawing is a common drawing method.

When the coating of large galvanized wire is blistered in the process of galvanizing, the bath temperature should be checked first. If the bath temperature is not low, and then strengthen the removal of oil before plating, to prevent the base metal in acid corrosion. If you pay attention to these problems, the bubbling phenomenon still exists, it should pay attention to the dosage and quality of additives, then you can stop adding additives, with high current electrolysis for a period of time, to reduce the content of additives, observe whether the bubbling phenomenon is improved. If there is no improvement, check whether the additive has been stored for too long or whether it contains too many impurities.

We basically know that the barbed wire fence generally has two kinds of ring and linear filamentous, the overall protective wire mesh selection of galvanized, stainless steel processing raw materials, long-term use is not easy to rust. Barbed wire fence uses stainless steel barbed wire, plastic coated barbed wire, aluminum coated barbed wire, galvanized barbed wire and other raw materials through special wire drawing into the strand planning, has a strong role in protection and maintenance. Widely used on both sides of the highway, grassland, gardens and other places, because it is a field protection product and therefore updated faster, so how to use the barbed wire fence after abandonment? Here are some of the uses of discarded blades.
