- For key and important parts with tensile strength greater than 1034Mpa, the stress should be removed at 200±10℃ for more than 1 hour before plating, and for carburized or surface hardened parts, the stress should be removed at 140±10℃ for more than 5 hours. The cleaning agent used for cleaning shall have no effect on the binding force of the coating and no corrosion on the substrate. Acid activation Acid activation solution should be able to remove corrosion products and oxide film (skin) on the surface of parts without excessive corrosion on the matrix.
Post time: 14-02-23Galvanized barbed wire (barbed wire) is made of galvanized barbed wire twisted on the main wire, so as to play a protective and isolation role. Among them twist weave way is divided into single twist weave and double twist weave. Construction methods include direct installation and spiral insertion.
- Stainless steel wire drawing is a metal working (stainless steel) process, is a popular surface treatment technology in the stainless steel and aluminum products industry today. It is the effect of drawing stainless steel and aluminum products. So galvanized wire and stainless steel wire are two different products. Defects such as surface film and surface inclusion can be found and treated by conventional techniques in order to locally remove the surface film and surface inclusion from the surface of galvanized iron wire. Excess foam is formed when soap and surfactants such as saponified fats are brought into the tank.
We must have a certain understanding of the hexagonal net, we are swayed by the beautiful shape of the hexagonal net, not only the shape of the hexagonal net is very beautiful, in fact, the practical value of survival is very high. The relevant information of Shaojie should be very clear to know that the high speed road guardrail network, hexagonal mesh of all kinds of guardrail network, the value of the high speed road is more prominent, it is not only used in a variety of roads, in a variety of sports ball venues and landslides to take care of, but also to reach the very close utility.
- Generally speaking, zinc is much more stable than iron, and will not rust in daily moisture or wet places. Z common galvanized iron wire equipment is usually we use the barbecue net, barbecue net generally requires to have a long service life, with galvanized iron wire equipment to wire on a layer of zinc, barbecue net is not easy to be corroded.
- Galvanized iron wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire) is made of low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, hot galvanized, cooling and other processes. Galvanized iron wire has good toughness and elasticity, zinc content can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. The products are widely used in construction, handicrafts, wire mesh, galvanized hook mesh, spackle mesh, highway fence, product packaging and daily civilian and other fields.
Now it is more used in the binding of the construction industry. Compared with ordinary iron wire, it is softer and has better luster. Use in daily life does not need to carry out maintenance and maintenance, save a lot of time, but also save the cost of maintenance and maintenance. Annealed wire has good stability, good corrosion resistance, greatly prolonging the service life. More kinds, can be selected according to different uses, making annealing wire device is simple, improve the utilization rate of the device. The material properties of annealed wire can meet different processing requirements.
If the surface of galvanized wire hair black, galvanized layer is thin and uneven, this galvanized wire is partly because the inventory storage time is longer, it may also be because the production technical requirements of galvanized wire, do not meet the standard standards and lead to galvanized wire quality problems. According to the use of galvanized wire is different, galvanized wire has soft and hard, so the galvanized wire for binding requires the flexibility of galvanized wire is better, the flexibility of galvanized wire is good, which can facilitate the operation of workers.
- The uniformity of galvanized wire is reflected in what aspects:
Ordinary blades installed on the walls of the barbed wire fence height in two metres of general construction cost in more than a dozen yuan a metre, but if the prison on the height of the wall construction modest have already reached the four or five meters so that every one meter of the cost of construction in 30-40 yuan, mainly because the work high above the risk is bigger. The construction cost is different, but the price of the blade barbed rope is the same. The construction cost is often higher than the product. In this way, the blade barbed rope factory recommends customers to use the blade barbed rope with better quality to avoid the tedious time and cost of subsequent removal and installation.

As we all know, the mechanism of resistance to atmospheric corrosion of zinc includes mechanical protection and electrochemical protection. Under the condition of atmospheric corrosion, there are ZnO, Zn(OH)2 and basic zinc carbonate protective film on the surface of zinc layer, which to a certain extent slows the corrosion of zinc. When this protective film (also known as white rust) is damaged, a new film will be formed.

Post time: 21-07-22Want to keep a dog friends need to know: choose suitable dog and family environment of the cage, the dog cage to consider the material, the size of the dog, space, location, whether easy to clean and so on. Let’s take a look at these aspects.
- There are many blade specifications, first of all there are three types: spiral type, straight line, spiral cross type. Different units, the strength of the protection of different rope models. The blade barbed wire is mainly made of low carbon steel wire and aluminum magnesium alloy wire by spraying and welding. The blade material of the blade barbed wire is attached to the core wire made of stainless steel wire with professional mechanical strength, so the blade barbed wire has the advantages of good strength and aging resistance.
- The strength of the hook net should be satisfactory: when the vehicle is traveling at 80 km/h, the hook net will not fall into the river when it bumps against the railings 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 important Bridges should be done well.
- In addition to these reasons, we should also pay attention to the tooling and process must be stable, and regular testing should be done to ensure the uniformity of galvanized layer.
- 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.
- According to the habit often according to the basic galvanized hardware before plating treatment method, as long as it does not contact with water can keep 5~7 years or so without rust, of course, if it is a salt water test, it will not be over 4 hours. Hot dip zinc is to use zinc tin solution to cover the hardware, and the rust prevention time is about five times that of traditional galvanizing. The general outdoor construction is to use hot dip zinc, and the salt water test can do about 36 hours.

- After a long time of use, it will not rust after the corrosion layer on the surface of the hot-dip galvanized barbed wire has problems, because the material inside the stainless steel barbed wire is the same as the material on the surface.
- Steel mesh benefits: Compared with traditional handmade steel mesh, steel mesh has better elasticity and even spacing. When pouring concrete, the steel mesh is not easy to bend, and the thickness of concrete protective layer is easy to control and even. In bridge deck surfacing, measure the protective layer of steel mesh. The pass rate is 95 percent.
The barbed wire factory will store the blade barbed wire inventory in the appropriate place, because it understands the product characteristics.
