After passivation treatment of galvanized layer, a layer of bright old and beautiful color passivation film can be generated, which can significantly improve its protective performance. There are many kinds of galvanized solution, which can be divided into cyanide plating solution and cyanide plating solution. Cyanide galvanizing solution has good dispersion and covering ability, coating crystallization is smooth and fine, simple operation, wide application range, has been used in production for a long time.
- When the temperature is running at the same temperature and the same heat is stored, the amount of iron dissolved is not the same. At around 500, the loss of iron increases sharply with the addition of temperature and insulation. It is lower or higher than 480~ 510c, and the loss of epitaxial iron is slower, and it is difficult to catch up with the duration. Therefore, everyone will call 480~ 510c the malignant melting zone.
Post time: 26-12-22Now large roll galvanized wire in our life the use of more and more, to galvanized wire products bring a great market, galvanized wire products are more and more types. The surface coating of good quality galvanized wire is continuous and smooth. When the plating parts are installed and combined, there can be no flow hanging, slag or drop remaining, and no surface defects such as iron exposure. Good quality galvanized wire, coating must be uniform, roughly uniform in copper sulfate solution soaking five times without exposing iron. And with hammering test does not bulge, do not fall off. This is a good galvanized wire should have characteristics.
There are too many fake things on the market now, so shoppers should learn how to distinguish the quality of galvanized wire, the right to protect their consumers’ rights and interests. Galvanizing process of galvanized wire products is a very effective metal anticorrosion method, and it is also widely used in other industrial fields. After galvanizing, iron wire is commonly used in metal structure equipment of various industries.
- The diameter of welded mesh wire for external walls is generally 2.2-ф4.0, and the mesh is generally 25-50.
Post time: 12-05-23- 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.
With the development of mining industry, the classification of pig iron is already very broad in our country, which can satisfy the demand of mechanical industry. In general, the iron used to produce large rolls of galvanized wire can be divided into two classes. A metal exercised directly from the iron ore through the iron making stroke, the composition of the ore is iron oxide, silica and other miscellaneous stones. When this ore is specially refined into metal iron, carbon, silicon, manganese, and other elements are mixed into it. The material produced in this way is called ordinary pig iron, which is also the material for the first grade.
- 5. Maintenance and cleaning in the future
- Annealing is to restore the plasticity of wire, improve the tensile strength of wire, hardness, elastic limit, etc., the wire after annealing is called annealing wire. In the production process of annealing wire, it is very important to ensure the quality of the finished wire, make the wire have certain strength and suitable degree of soft and hard. The annealing temperature is between 800 ℃ and 850℃, and the length of furnace tube is lengthened appropriately for enough holding time.
The main difference is carbon content. Iron has a carbon content of 2.11 percent or more, while steel has a carbon content of 2.11 percent or less. Iron-carbon alloys with carbon content of more than 2.11% are cast iron (pig iron), which are basically not malleable and cannot be drawn into wire. Secondly, the content of impurities is different, and the content of harmful impurities such as sulfur and phosphorus in steel is smaller. Wire general color key, wire color light point, white point.
- 3, pay attention to the cage height
The temperature of large roll galvanized wire should be controlled at 30 to 50℃ during electroplating. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used. Continuous production does not need heating, but needs cooling. Cooling can be in the groove side row thin wall plastic pipe, through the flow of tap water cooling, can also be used as a titanium pipe temperature control device.

Post time: 28-02-23Dog cage mainly by welding, spraying, injection molding, surface treatment, electroplating dog cage is made of high quality steel wire, dog cages are with plastic and plastic surface treatment, electrophoresis, chrome plating, galvanized, imitation gold, etc., according to the customer request processing, respectively, also can be customized to sample, dog cage assembly of compact structure, neat and beautiful appearance, make folding and remove the cage is more convenient and quick, won’t take up too much space.
Razor blade barbed rope has been widely used in military sites, prisons, government agencies, banks in the world. The walls of living quarters, private homes, villas, fences, doors and Windows, highways, railway guardrail and border lines and other protection and security.
Hot dip galvanized welding mesh is made of iron wire, processed by precision automatic mechanical technology. The mesh surface is smooth, the structure is strong, and the integrity is strong. Even if the local cutting or local pressure is not relaxed, the hot dip zinc is processed. Hot dip galvanized welding mesh surface white color, thick zinc layer, high zinc content at the solder joint, uniform mesh, flat mesh surface, solder joint tensile resistance, high corrosion resistance. It has the advantages that ordinary barbed wire does not have.
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.
- Large hexagonal net called stone cage net, mainly used for mountain preparedness protection, hydraulic construction, etc. Small wire hexagonal net is used as a good material for culture, will twist the hexagonal net in the welding of the iron frame on the hexagonal net welding into chicken cage, pigeon cage, rabbit cage and other cage, hexagonal net is an excellent material for culture with net.
Cold plating is a physical treatment method, the zinc is simple and uneven, the amount of zinc is also less than in the corrosion and rust prevention and chemical disposal of hot plating; The amount of hot zinc plating is relatively thick, the surface of the disposal is flat on average, and it is not easy to fall off. A layer of alloy composed of zinc and metal has very strong oxidation ability, and there is a layer of pure zinc on the outside of this layer of alloy, which is why hot plating is thicker and stronger than cold plating. Under the condition of high degree of natural recovery, galvanized hook net can play a very good maintenance effect on the environment, it is not afraid of wind and rain, it is the battle machine in the hook net, much stronger than the dip plastic hook net.
Three methods of twisting the thorn rope: forward twisting, reverse twisting, reverse twisting.
Spray powder mainly acrylic powder, polyester powder and so on. Dipping is a kind of plastic coating process, that is, the plastic coating on the matrix, generally metal, such as: daily use of clothes hangers, pliers handles, scissors on the rubber sleeve, various handrails, etc. Plastic immersion is to heat the metal to spray plastic powder evenly on the metal to form a plastic film, or heat immersion liquid into the metal to cool it and then plastic coating on the metal surface.
Post time: 16-06-22To many people, a dog cage looks like a prison, but for dogs who have been raised on cage training, it is their home and shelter. A cage should be a comfortable place. Never put a dog in a cage for no reason. They will see it as punishment. (Why do many dogs fail to adapt to their owners’ commands, because whether the paparazzi can come out or not, it is also seen as a punishment.
