Flange Head Self-Drilling Screws find extensive use in various industries, from construction and automotive to manufacturing and engineering
Now more and more people are buying the barbed rope, but there are often a lot of people do not know the specifications of the blade barbed rope when they buy, here is to introduce the specific characteristics of the blade barbed rope.
Many people do not know how to choose high quality cut wire, I will give you a detailed introduction. The raw material of cutting wire is divided into: stainless steel cutting wire, copper cutting wire, steel wire cutting wire, copper plated steel wire cutting wire, galvanized steel wire cutting wire, iron wire cutting wire, aluminum wire cutting wire and so on.
Post time: 22-11-22National standards on the use of wire mesh standards have certain requirements, diameter and mesh size matching use, rather than simply diameter, on the plaster layer to use the mesh should not be greater than 20×20, diameter is not easy to be less than 1mm, just choose diameter is not much meaning, choose 40×40×0.9 and choose 10×10×0.6 wire mesh, Which is better? I’m afraid it’s 10 by 10 by 0.6.
- The galvanized requirements of the parts to be plated: the surface of the parts to be plated should be smooth, and there is no dirt that cannot be removed by pickling method. Such as paint, grease, cement, asphalt and excessive rotten harmful substances; All welds of welded components shall be sealed without air; Pipe fittings and containers must have exhaust and zinc inlet holes; The workpiece should be finished welded steel pipe without thread, if any thread should be protected.
- At present, some manufacturers also use the process of sandblasting equipment for wire pretreatment, sandblasting process is carried out in the sandblasting room, but in the process of sandblasting, dust will permeate the whole sandblasting room, produce a lot of dust that is not easy to collect, and if the dust will be discharged at will.
- There are many kinds of zinc plating solution, which can be divided into plating solution and no plating solution according to its properties. The galvanized liquid has good dispersion and covering property, the coating crystal is smooth and fine, the operation is simple, the application range is wide, and the long-term use is in the production. However, due to the toxic substances contained in the plating solution, the gas escaping from the plating process has great harm to the health of workers, and the waste water must be treated strictly before discharge.
Post time: 14-03-23There are many ways to choose the blade stabbing rope, and it is necessary to choose reasonably when choosing. Blade barbed rope is very good in the market reputation, and different types of blade barbed rope can play different roles, so how should we choose blade barbed rope? What are the main points?
A. When the thickness of the plating is 3-4 mm, the zinc adhesion should be less than 460g/m, that is, the average thickness of the zinc layer is not less than 65 microns.
Barbed wire was used as a barrier to livestock theft, for one thing, because the surface was covered with sharp spikes that made it very difficult to penetrate through the barbed wire. On the other hand, it is because livestock generally have the habit of running into each other, which makes livestock dare not run into each other with the barbed rope, thus saving the user’s use cost.
Fourth, the difference between 201 and 304 is the problem of nickel. And the price of 304 is relatively expensive now, generally close to 20,000 yuan per ton, but 304 can at least ensure that it will not rust in the process of use. (Experiment with potions)
Select cut silk first to ensure that the raw material of the silk is exactly the raw material you need, the raw material will be used well. Choose high straightness, so that the length of the truncation will be the same, will not show a lot of length difference, the length of the truncated wire is a very important element to choose the truncated wire.
The height of the shield should not be less than two meters. The length of the shield should be the width of the journey and the extension 10 meters away. The vertical load of the handrail on the bridge is 1.2KM/m, and the horizontal external load is 2.5KM/m, both of which should be calculated separately. Galvanized hook mesh belongs to a hook mesh, it is the selection of galvanized wire, hot-dip galvanized wire as raw materials, woven through the hook mesh truncated.
We must have a certain understanding of the hexagonal network, we are the beautiful shape of the hexagonal network, more than the appearance of the hexagonal network is very beautiful, in fact, the practical value of survival is very high. To introduce the relevant information should be very clearly know the highway guardrail net, hexagonal wire netting in all kinds of fence netting, in the value of the high-speed on the road more MaoJian, it not only be used in all kinds of road, in a sports ball games venue and try our best to take care of landslides, also has reached very matter effectiveness.
Post time: 18-10-22The 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.
Pay attention to safety in line collection and operation, others without the consent of the monitor, Ben have to get on the bus operation. The reels should be placed lightly, stacked firmly and neatly, not more than 5 reels. Direct contact with acid and alkali must be prohibited. When the acid fog exceeds the specified target of the state, measures should be taken to control it in time, otherwise production is not allowed.
- The surface of the galvanized wire deposition layer before galvanized to remove the surface film layer, surface inclusion and other defects to the local, can be found and treated by conventional technology. Excess foam is caused by soaps and saponable fatty surfactants being brought into the tank. Moderate foam formation rates may be harmless.
Stainless steel blade barbed rope under normal circumstances, basically 20 or 30 years is no problem, but because of the problem of its own material will appear a certain degree of rust, this is also because usually stainless steel blade barbed rope used by the material is 304 material, in daily use if in a long-term humid environment will cause certain corrosion. But usually users buy stainless steel blade barbed rope is basically life will not have problems users can also rest assured to use.
Steel wire and iron wire have a lot of similarities, but carefully distinguish, you will find that they are not only different in the material, but also in the product characteristics are very different. So when choosing, make sure you make a clear distinction between the two. Steel wire factory introduces steel wire carbon structure steel made above, generally not galvanized, used for machinery, spring. Black and hard; Iron wire: low carbon steel (mild steel), galvanized, used for joining and wrapping. It’s white and soft.
Post time: 06-09-22- Pure zinc is more stable in dry air. In moist air or water containing carbon dioxide and oxygen, the surface will generate a layer of basic zinc carbonate based thin film layer, which can delay the corrosion rate of zinc layer. Comparison of corrosion resistance of zinc coating in aqueous solution of acid, alkali and sodium chloride; It is also resistant to corrosion in atmospheres containing carbon dioxide and hydrogen sulfide and in oceanic atmospheres; In high temperature and high humidity air and contain organic acid atmosphere is small, galvanized layer is also easy to be corroded.
Small and medium-sized cat cages, dog cages and fences are mostly made of pure iron wire, wire diameter is generally between 2-5mm. Of course, the larger the cage, the thicker the wire, because the larger cage needs to withstand more force.
