- 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.
Pet cage is generally made of high quality iron wire, low carbon steel wire, stainless steel wire welding, its characteristics are beautiful, light, folding, easy to store. Pet cage surface treatment is generally: cold galvanizing, hot galvanizing, spraying, dipping, chrome plating, nickel plating and other methods. Pet cage is mainly used for family breeding pets and protection. Tianfu metal products company specializes in the production of various specifications of pet cage such as pigeon cage, dog cage, bird cage, parrot cage and so on.
- The coating on the surface of the welding core is called the coating. The coating of electrode plays a very important role in the welding process. If the photoelectrode without drug skin is used for welding, in the welding process, oxygen and nitrogen in the air will invade a large number of molten metal, metal iron and beneficial elements such as carbon, silicon, manganese oxidation and nitriding to form various oxides and nitrides, and residual in the weld, resulting in slag inclusion or cracks in the weld. The gas in the weld pool may produce a large number of pores in the weld. These factors can greatly reduce the mechanical properties of the weld and make it brittle.
The size of the galvanized layer of galvanized iron wire is related to the anti-corrosion ability and application effect of galvanized wire. The thickness of the galvanized layer of the general standard galvanized wire products should be tested after the product is formed. There are three specific test methods. Weighing method and cross section microscopy method are destructive experimental methods, and magnetic method is a relatively rigorous non-destructive method, but the measurement steps and requirements are relatively high, so they are rarely used in specific applications. The first two methods are intuitive and common methods.
- Copper sulfate point test is a simple way to quickly distinguish ordinary carbon steel and all types of stainless steel wire rope. The concentration of copper sulfate solution used is 5%-10%. Before the point test, the experimental area should be thoroughly removed from the oil or other impurities, and a small area should be polished by grinding machine or soft grinding cloth, and then the test liquid drops to the grinding place. Ordinary carbon steel or iron in a few seconds will form a layer of outer metal copper, and the surface of stainless steel does not produce copper precipitation or display copper color.
First of all, we need to pay attention to the material of the barbed wire, because the galvanized barbed wire itself includes cold plating and hot plating. The properties and prices of the two are obviously different, and it is easy to be confused by a little negligence.
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.
Domestic iron wire factory has been able to consume wire rope, radial low steel wire, umbrella steel wire, spring steel wire, bicycle saddle spring steel wire and other products. In the 1980s, hot – plated low carbon steel wire, fan net cover steel wire, carbon structure steel wire, bed steel wire and so on were also published. The elongation of wire is increased after annealing. Make the product more soft and increase the scope of application of the wire.
Steel wire and iron wire have many similarities, but carefully distinguish, will find that they are not only different in the material, but also in the product characteristics of the great difference. So when choosing, be sure to make a clear distinction between the two. Steel wire factory introduces steel wire carbon structural steel made above, generally not galvanized, used for machinery, spring. Black, very hard; Wire: made of mild steel (mild steel), galvanized, used for joining and binding. White and soft.
When galvanized wire out of the light plating should be carried out light treatment. The bath temperature of galvanized wire should be controlled well. Galvanized wire, also known as hot dip zinc and hot dip galvanized, is an effective way of metal corrosion prevention, mainly used in various industries of metal structure facilities. It is to immerse the steel parts after rust removal into the molten zinc liquid at about 500℃, so that the surface of the steel member is attached with zinc layer, so as to play the purpose of anticorrosion.
- 5, after the light plating should be carried out light treatment.
With the development of mining industry, pig iron classification in Our country has been very extensive, can satisfy the demand of machinery industry. In general, iron used to produce large coils of galvanized wire can be divided into two classes. A metal produced directly from iron ore and iron smelting, consisting of iron oxide, silicon dioxide, and other miscellaneous stones. When this ore is specially refined into metal iron, carbon, silicon, manganese, and other elements are mixed in, so that the refined material is called general pig iron, is also for the initial grade of the material.
Post time: 26-05-22- Compared with electric galvanized iron wire, hot dip galvanized iron wire has higher zinc layer, better anti-corrosion performance, and is suitable for the more important anti-corrosion and anti-rust status.

Nestor rolling cage, high-speed railway Nestor rolling cage and railway Nestor rolling cage are all produced, sold and installed in accordance with the technical requirements of the reference drawing of railway line 2012-8001. Nestor rolling cage is a kind of protective equipment emerging in railway in recent years. Nestor rolling cage is connected by Nestor connecting clip on the longitudinal tensile rib fixed on the bracket. The longitudinal tension and the support are connected with the Φ2.5mm cold-drawn galvanized steel wire around 2 laps and then tightened. The support is set in the column and the middle of the span of the protective fence of 3m. The other spans are only set with the upper column, and the support and the protective fence are connected with the bracket hoop. For the protective fence that has been installed with metal mesh, the Nestor roller cage is directly fixed on the transverse sheet and wire of the metal mesh with the cold-drawn galvanized steel wire of 2.5mm or the Nestor connection fastener.
Specific requirements for the safety of galvanized wire production: clean up all tools and other objects that hinder production in the galvanized wire production environment. Operators in the pickling process, pay attention to the action should be careful, not careless, into the pickling tank must be handled lightly, to prevent splashing on the body. When adding acid, the acid must be slowly poured into the water. It is forbidden to pour the water into the acid, so as to prevent the acid from splashing out and hurting people. Do not hurt yourself or others.
Hot dip galvanizing, also known as hot dip zinc, is the method of forming a layer of zinc coating on the surface of the workpiece after oil removal and rust removal, showing a clean and infiltrating surface, immediately immersed in the plating tank of zinc melting in advance. Cold galvanizing is the same after the removal of oil, in addition to lure, showing no pollution, infiltration of the workpiece hung into a special electroplating tank on the cathode, the anode with zinc. Switch on the DC power supply, zinc ions on the anode migrate to the cathode, and discharge on the cathode, so that the workpiece is coated with a layer of zinc layer hot dip galvanizing method.
Post time: 19-08-22- The COMBINATION OF disSIMILAR METALS, such as steel and copper, tin, lead and other non-ferrous metals, during hot dip operation, the dissolution of this non-metal will cause the change of zinc film structure. Also like the combination of old and new steel, in pickling operation, the new material is easy to pickling over. In addition, such as part of the processed components, excessive pickling at the processing place is also.
