- Zinc coating on steel and ferrous metal plays an anodic role, it is commonly used for those parts subjected to atmospheric or water action, but zinc coating only when the water temperature below 60℃, the anode properties. When the temperature is higher, the potential changes and the zinc to iron becomes the cathode. Therefore, for parts subjected to hot water (such as steam boilers), the zinc skeleton must be approximately 70 microns thick and void free. For parts subjected to low or normal temperature or atmospheric action, zinc coating without pinholes is not necessary.
There are three methods to detect the thickness of zinc layer of galvanized wire: weighing method, cross section microscopy method and magnetic method, among which the first two experiments will cause certain damage to galvanized wire, including the length of galvanized wire and the reduction of dosage. The general detection of galvanized wire galvanized layer is detected by magnetic method, which is also a more intuitive and convenient method. The standard of galvanized layer thickness is related to the wire diameter of galvanized wire. The larger the wire diameter of galvanized wire, the thicker the galvanized layer is. It is the thickness of galvanized layer and cast iron after centrifugal separation.
Magnetic test method is the original common difference between austenitic stainless steel and ferritic stainless steel simple way, austenitic stainless steel is wrong magnetic steel, but after cold processing under large pressure will have a slight magnetic; But pure chrome steel and low alloy steel are strong magnetic steel.
After annealing, the wire will become soft, flexibility will increase, iron is a relatively active metal, and more active than hydrogen, so it is a good reducing agent. At room temperature, iron is not easy to react with oxygen, sulfur, chlorine and other non-metallic elements in dry air. Its production cost is lower, its use and scale are also relatively wide, and it has better protective function. Therefore, it is an important material for steel parts in strict working environment.
- Wire rod to stop normalizing or soxaustenitizing treatment, large specifications with spheroidizing annealing instead. In the middle, especially before the waste product drawing process of thermal disposal throughout the selection of soxaustenitizing disposal. Decarbonization should be prevented during thermal disposal. Sulfuric acid or hydrochloric acid pickling was used to remove the oxide sheet after hot treatment. Coating (see lubrication carrier) can be dipped in lime, phosphating, borax disposal or copper plating.
- D, coating adhesion; The zinc layer of the plating parts should be firmly combined with the base metal with sufficient adhesion strength, and will not fall off or bulge after the hammer test.
Small and medium-sized cat cage, dog cage and fence are mostly pure wire welding, wire diameter is generally between 2-5mm. Of course, the larger the cage, the thicker the wire, because the larger cage has to withstand more force.
- Most people think that the fine wire of the front and back twist barbed wire is not as thick and durable as common sense, but the front and back twist barbed wire is made of hot-dip galvanized steel wire, which is more than three times greater than the tensile strength of iron wire, and the amount of zinc added is not less than hot-dip wire
Post time: 28-04-22- The application range of small hexagonal net is also relatively wide, can be used for building wall fixed insulation layer, pipeline, boiler fixed insulation, decoration and other fields.
Paint on the galvanized layer, the binding force between each other and the baking temperature of the paint has a great relationship, after galvanized coating alkyd paint, adhesion is no problem. Galvanized amino paint, paint adhesion is not good. Do two bottom two surface, adhesion is ok, if the two bottom two surface to two bottom three surface, that is, more paint, more baking once, again test adhesion is very poor, poor to the paint from the galvanized layer of pieces torn off.
Stainless steel barbed wire is often used in various engineering projects because of its good anti-corrosion ability, but it is difficult for ordinary families to accept because of its relatively high price. So what material of barbed rope anticorrosion ability is better?
- A lot of pet carriers are designed with a small box at the base, so that pets can clean up when they poo. At the same time, it is also convenient for pets to clean up. For example, if there is no box for leaking excreta, pet excreta will be on the ground, which is quite unsanitary. If you have a box it’s easy to take the box out and clean the trash so it doesn’t get all over the place, so it’s more hygienic.
- Hexagonal net weaving methods: positive twist, reverse twist, two-way twisting, first editing after plating, first plating after editing, and then divided into hot dip galvanized hexagonal net, electric galvanized hexagonal net, PVC plastic coated hexagonal net, stainless steel hexagonal net, etc.
- Origin: Hebei
2, the production and installation is simple and fast, the use of patented friction connection or special connection accessories for installation, greatly improve the installation efficiency.
- 1, first of all, the net surface is smooth, mesh are four lines, pitch is the same, whether the weft wire bending (note: the net width is the length of the weft wire), normal weft wire passes through the straight wire of welded wire mesh, with accurate time and the silk repeated welding, make the pitch of welded wire mesh is consistent, with smooth surface, into a square hole, when the net vertical position from the top downwards see, weft wire is straight.
Uses: water conservancy engineering, river regulation engineering, dike engineering, ecological protection engineering, channel lining, road engineering, river bank reinforcement, ocean engineering, landscape design engineering, bridge reinforcement, railway and highway slope protection, retaining wall, ecological river bank slope regulation and other engineering.
- How much does a spike rope weigh in a meter? In fact, after figuring out how many meters a kilogram of barbed rope, this problem will be solved, and it is OK to divide a kilogram directly by the number of meters.
- The screen is made into a box-like container, with stone filled with cages, can be used to protect and support seawall, hillside, road and bridge, reservoir and other civil engineering, flood control and flood resistance is a good material.
Post time: 19-10-22- In the selection of birdcage, the characteristics of the birds, the way of daily management, the impact of the surrounding environment and so on should be considered. Therefore, it is necessary to have requirements on the shape, structure and technology of the cage, so that the cage can not only be suitable for the birds’ activities, but also delicate and beautiful.
- The blade thorn rope is formed by the punching steel plate and mechanically rolled on the steel wire. The width of the blade is 22mm, the vertical distance between the two blades is 15mm, the longitudinal distance between the blade is 34mm, and the diameter of the core wire is 2.5mm. The blade is made of Q195 steel plate with 0.5mm thickness.
Post time: 09-05-22After annealing, the extension rate of galvanized wire is increased, making the product more soft and increasing the scope of application of galvanized wire. After electric galvanized hot galvanized, electroplated copper and other widely used screen production. Building reinforcement binding with galvanized wire mesh braided with the first after plating, plating and other methods, after treatment of galvanized wire mesh or steel wire mesh, has good corrosion resistance, oxidation resistance characteristics, can be used in construction, petroleum, chemical, aquaculture, garden protection, food processing and other industries reinforcement, protection and heat preservation.
Application: Mainly used in communication devices, medical equipment and braided mesh, brush, steel cable, filter screen, high pressure pipe, construction, technical products and other professional electric galvanized wire: is a low carbon steel as core wire, metal composite materials processed by wire drawing, electric galvanized technology.
- 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.
Galvanized hexagonal mesh weaving process: double stranded hexagonal mesh, can be divided into three screws and five screws.
- When choosing a dog cage, we should pay attention to its material. Generally speaking, it is mainly composed of four materials, plastic, wire, square tube and stainless steel.
- Packaging: Welding mesh is generally packed with moisture-proof paper (color is mostly gray, yellow, plus trademarks, certificates, etc.), some like 0.3-0.6mm domestic sales of small wire diameter welding mesh, because the wire is relatively soft, coupled with small rolls, customers often require baling and bagging treatment, to prevent damage caused by shipment, etc. The wire of the electric welding net is straight, and also with wavy bend (also known as Dutch net). According to the shape of the mesh surface can be divided into: electric welding mesh and electric welding mesh roll.
- In addition, hot-dip galvanized wire also needs to pay attention to maintenance and maintenance during use. Although it has good corrosion resistance, the zinc-iron alloy protective layer of hot-dip galvanized wire will gradually wear out after a long time of use. Therefore, regular inspection and maintenance of the surface of hot-dip galvanized wire, such as recoating or anti-corrosion treatment, helps to extend its service life.
- Choose a cage with a proper structure, such as a tray under the cage so that the dog can urinate in the cage. It’s also easy for the owner to clean up.
