When opening, only one side of the gill net needs to be fixed, and then the gill net needs to be opened in the opposite direction. Pay attention to the spacing of the holes should not be too large, otherwise it will affect the aesthetic effect. As long as the time to slowly return to the line, simple operation, convenient construction.

  • In order to improve the corrosion resistance of steel pipe, the general steel pipe is galvanized. Galvanized steel pipe is divided into hot dip galvanized and electric galvanized. The layer of hot dip galvanized is thick, the cost of electric galvanized is low, and the surface is not very smooth. Used for steel blowing oxygen pipe, generally with small diameter welded steel pipe, specifications from 3/8-2 inches of eight. Made of 08, 10, 15, 20 or 195-Q235 steel strip, in order to prevent corrosion, some should be aluminized.

  • Cold galvanizing is also called electric galvanizing. It is the use of electrolytic equipment to remove oil, pickling, and then put the pipe into the solution of zinc salt, and connect the anode of the electrolytic equipment, place zinc plate on the opposite side of the pipe, and connect the positive pole of the electrolytic equipment to the power supply. A layer of zinc is deposited on the pipe fitting by directional movement of an electric current from the positive pole to the negative pole. Cold plated pipe fitting is processed before galvanizing.

  • Powder coating color is divided into: blade thorn rope blue, grass green, dark green, yellow. Spray blade gill net is made of hot-dip galvanized steel plate or stainless steel sheet stamped out of sharp knife sheet, high tension galvanized steel wire or stainless steel wire as core wire combination of blocking devices. Because the shape of the thorn rope is not easy to contact, so it can reach excellent protective barrier effect. The primary raw materials of products are galvanized sheet, stainless steel plate, high quality low carbon steel wire (electric galvanized, hot galvanized, coated plastic, plastic spray) wire, blue, green, yellow and other colors.

  • 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.

  • Hexagonal mesh is made of galvanized iron wire woven by automatic mesh machine, mesh into regular hexagonal, mesh standard, beautiful, mesh size can be customized according to customer requirements, usually 27mm,20mm, 13mm, wire diameter from 0.40mm to 1.20mm, to meet the requirements of different customers.

  • 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.

  • Therefore, when zinc reaches saturation in the solid melt, the two elements of zinc and iron atoms diffuse with each other, and the zinc atoms diffused into (or infiltrated into) the iron matrix migrate in the lattice of the matrix and gradually form an alloy with iron, while the iron diffused into the molten zinc liquid forms an intermetallic compound FeZn13 with zinc and sinks into the bottom of the hot-dip galvanized pot, that is, zinc slag. When the workpiece is removed from the zinc leaching solution, the surface of the pure zinc layer is formed, which is hexagonal crystal, and its iron content is not more than 0.003%.

  • There are three main factors affecting corrosion of stainless steel pet cages in Dalian:

  • Galvanized electric welding net is widely used in industrial production, agriculture, engineering construction, transportation, mining and other processing and manufacturing industries. Such as machinery and equipment protective cover, animal guardrail, pot flower guardrail, window fence, safety exit guardrail, poultry cage, egg basket and home office food industry basket, paper basket and design decoration.

  • 3. The transport, storage and use of the binder of galvanized wire mesh should adopt safety and fire prevention methods according to the relevant regulations, so as to be safer.

  • Zinc coating on steel and ferrous metal plays an anodic role, it is commonly used for those parts subjected to atmospheric or water action, but zinc coating only when the water temperature below 60℃, the anode properties. When the temperature is higher, the potential changes and the zinc to iron becomes the cathode. Therefore, for parts subjected to hot water (such as steam boilers), the zinc skeleton must be approximately 70 microns thick and void free. For parts subjected to low or normal temperature or atmospheric action, zinc coating without pinholes is not necessary.

  • 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. When the galvanized wire out of light plating should be carried out light treatment, the galvanized wire bath to control the temperature. Now the quality level of galvanized wire on the market is not equal, galvanized wire is also called hot dip zinc and hot dip galvanized, is an effective way of metal corrosion prevention, mainly used in various industries of metal structure facilities.

  • Removal of surface-active substances by activated carbon matting. Or make the bubble unstable according to overworry, these are all reasonable countermeasures; Other strategies should also be used to minimize the amount of surfactant taken in. The introduction of organic matter can make the electroplating process speed drop sharply. Galvanized iron wire blackening can be effectively prevented, such as: the work site to keep dry, reduce and do not use chemicals, operators with clean gloves and so on. In addition, hot dipping zinc factory can be required, after dipping zinc must be passivation treatment, passivation treatment of zinc has a better anti-discoloration effect, can effectively prolong the discoloration time, the combination of the two, discoloration should be able to solve.
