After annealing, iron wire will become soft, flexibility will increase, iron is a more active metal, and more active than hydrogen, so it is a good reducing agent. At room temperature, iron in the dry air is not easy to react with oxygen, sulfur, chlorine and other non-metallic elements, its production cost is lower, use and scale is wider, better protection function, so it is an important material for iron and steel parts in a strict working environment.
Galvanized hook net cost is low: galvanized process is faster than other coating construction method, and can avoid the installation of time required on the site brushing; Galvanized hook net features: not easy to corrosion, long life, strong practicality, uniform mesh, smooth net surface, simple weaving, beautiful and generous, high quality mesh, wide mesh, thick wire diameter. Can do breeding protection net, coal mine protection net, court protection net, stadium fence net, training field protection net, slope protection, green enclosure, river, building, residential district safety protection, workshop/warehouse isolation, etc..
③ The galvanized iron wire shall not be damaged when it is tightened.When a guided weight progress or repeated guided weight progress at a smaller height (driving) or left-handed and right-handed rope is used in pairs, ordinary wire rope can be selected. The determination of wire rope rotation should comply with: right-handed rope groove drum recommended use of left-handed wire rope: on the contrary, left-handed rope groove drum should use right-handed wire rope.
Silk screen material can choose galvanized wire, stainless steel wire, copper wire, plastic coated wire, paint wire, etc., different materials used in different fields, such as construction, breeding, decoration, etc.
The main raw material of blade barbed rope is galvanized wire and galvanized sheet, because the price of galvanized sheet is more expensive than galvanized wire, so it is directly reflected in the price of the sales of blade barbed rope. There is also the difference in processing technology also led to the difference in the price of the blade thorn rope. The traditional barbed rope is mechanically twisted, which uses less labor and has high production efficiency. But the blade is after two mechanical processing in the manual processing operation before the appearance. So whether from the labor force or from the production efficiency also said there is a large gap. These factors lead to the price of blade thorn rope is more expensive the main factor.
Cold wire drawing is mainly used in the production of hardened low carbon steel wire, with a diameter of 8 mm steel bar to play a fixed role in the development of the construction industry has played a role in promoting the development of the construction industry, widely used. The bonding and anchorage performance between cold wire drawing and concrete is good. When used in components, the phenomenon of cracking in the anchorage area of components and damage caused by steel wire slip is fundamentally eliminated, and the bearing capacity and anti-cracking capacity of the end of components are improved.
The protective duration of galvanized iron wire is closely related to the thickness of galvanized iron wire. In general, zinc layer thickness needs to be very high in dry main gas and indoor applications, but in harsh environments. Therefore, in the selection of galvanized layer thickness, the impact of the environment should be considered. If galvanized iron wire products of different diameters are required, material selection and coating should be controlled reasonably.
The key and important parts with tensile strength greater than 1034Mpa should be relieved of stress at 200±10℃ for more than 1 hour before plating, and the carburized or surface hardened parts should be relieved of stress 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.Wire mesh production of general selection of low carbon wire, after fine and accurate active welding equipment processing, the selection of galvanized process surface treatment. After the completion of the product, the net surface is smooth and regular, good integrity, strong and consolidated, even if part of the choice or pressure will not appear lax phenomenon.
4, when the greenhouse special electric galvanized shaft wire from the well and winding to the roll, be sure to clean up the well fluid, mud sand and other things stuck on the wire, and also coated with protective oil.
Now 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 is: positive and negative twisting barbed rope high service lifeWhen using these two products, it is obvious that there is a gap between them. By pulling or bending the wire, it is often difficult to restore the original, for example, if the same place is repeatedly bent, it will be found that it has broken, and the cold drawing wire will not. Cold drawing wire compared with iron wire, its hardness, tensile resistance, bending ability is greatly enhanced, suitable for building materials.
