Because of its light weight, strength is relatively large has gradually begun to replace the original column. At the same time, due to the relatively uniform specifications, the barbed rope installation is also more beautiful. The direct spacing of the barbed rope is relatively fixed, which can effectively prevent crossing. At the same time, the mesh at the bottom is relatively dense, while the mesh at the top is relatively loose, which can save resources.
The 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.
Most people in addition to pay attention to the price of barbed rope, many people for hot-dip galvanized barbed rope or cold galvanized barbed rope will have questions, in fact, these two products, the price difference is not very big, so how to choose hot-dip galvanized barbed rope and electric galvanized barbed rope?
This process has no mold, low processing cost, easy forming, can process a variety of shapes and other characteristics are widely used. But the products of the guardrail are powder impregnated plastic. According to whether it needs heating, it is divided into hot dipping and cold dipping. According to the raw materials of dipping, it can be divided into liquid dipping and powder dipping. Hot-dip galvanizing, as a metal anticorrosion method, is usually to put the steel structure to be derusted into the zinc liquid at about 500℃, so that the zinc layer is attached to the surface of the steel structure.
Wire mesh welding after galvanized is through the end of the welding and then the cold company to make wire mesh wire mesh steel mesh construction mesh floor heating mesh galvanized or hot galvanized. After the first galvanized welding is to change the wire mesh, after the end of welding can see the welding spot; The two processes are different prices are also very different, the cost of the first plating after welding is low, the appearance is smooth, and the cost of the first welding after plating is higher, not easy to rust.
Pet cage You can choose a pet cage that you like or find suitable. It is recommended that you buy a metal cage, with a metal tray at the bottom, of course, the better is stainless steel, plastic can also be, but the plastic tray is very easy to be bitten by pets and damage, plastic tray is also easy to be pet uric acid corrosion, and plastic products are also low, not durable. So pet cages are usually made of metal. This will prevent the pet from entering the house and causing damage, while also providing it with maintenance and not getting sick from running around and touching dirty things.
The shape of the cage has round, square, octagonal, hexagonal and other shapes. Because the circular space uses a large area, it is more suitable for the activities of birds, and it is not easy to get hurt, so it is popular with everyone. A cage is dear to a man who loves birds, for it is inhabited by his master’s birds. If well maintained, it can be maintained for many years. Let’s look at how to maintain the cage.
1. Grid structure is simple, beautiful and practical; 2. Easy to transport, installation is not limited by terrain relief; 3. Especially for mountain, slope, multi-curved area adaptability; 4. Medium low price, suitable for large area use. Main market: railway, highway closed net, yard fence, residential guardrail, all kinds of isolation net.
If the zinc coating is good, but when the light comes out in 3% nitric acid, there is a dark shadow on the coating, and the film is brown when passivation occurs, which may be caused by foreign metal impurities such as copper or lead in the galvanized liquid. When there is a problem in the process of galvanizing, check the temperature and current density first, and then measure and adjust the content of zinc and sodium hydroxide in the bath through the analysis of the bath. Whether DPE levels are low can be determined by Hull cell test.
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.
