Packaging: electric welding net general packaging for moisture-proof paper (color is mostly gray white, yellow, plus trademarks, certificates, etc.), some like 0.3-0.6mm domestic sales of small wire diameter electric welding net, because the wire is relatively soft, coupled with small volume, customers often require packing processing, in order to prevent shipment caused by damage. The wire of electric welding mesh has straight, also has a wavy bend (also known as the Dutch net).
If the zinc coating is good, but in 3% nitric acid when the light, the coating has dark shadow, passivation occurs when the film is brown, may be caused by foreign metal impurities such as copper or lead in the galvanizing liquid. When problems occur in the process of galvanizing large coil galvanized wire, the temperature and current density are checked first, and then the content of zinc and sodium hydroxide in the plating solution is measured and adjusted through the analysis of the plating solution. Whether DPE content is low can be determined by hull cell test.
No matter how good the quality of hot-dip galvanized barbed rope is, it is only attached to the surface of the wire with galvanized layer, and with the cause of chemical reaction, the zinc layer on the surface will gradually lose its effect because of oxidation reaction, which is more prominent in the humid area of the environment. And because, after all, the wire will rust, so the quality of hot-dip galvanized barbed rope is certainly not up to the level of stainless steel barbed rope.
Under any application environment, users hope that the welding mesh has better strength, as long as it has improved in strength, it will make better use of the demand, but to make the strength of this product improve, also need to have many conditions, to see what kind of data manufacturers have in production, the strength of the product is the strength of the data, But a manufacturer does not meet the strength requirements in the data, and naturally, it cannot make the strength of the product improve after all, so this is the condition.
And high quality data is constrained by production cost and production conditions, so some welding mesh manufacturers do not meet this requirement, natural in this case, there is no way to improve the strength of the product. In addition to the data, there is the production process, even if it is the best data, but the manufacturer does not meet the production process requirements in the welding, it will also form the product under high pressure welding, so this is also a decline in strength, the process conditions of different manufacturers are also very different, so it forms the market above the product has a difference in strength.
Galvanized iron wire can be divided into hot-dip galvanized iron wire and cold galvanized iron wire according to different processing methods. Galvanized iron wire is more prominent in its corrosion resistance. Galvanized iron wire has good toughness and elasticity, the amount of zinc can reach 300 g/square meter, with thick galvanized layer, strong corrosion resistance and other characteristics. Galvanized iron wire products are widely used in construction, handicrafts, wire mesh preparation, the production of galvanized hook mesh, wall mesh, highway guardrail, product packaging and daily civilian and other fields.
With the development of mining industry, pig iron classification in Our country has been very extensive, can satisfy the demand of machinery industry. In general, iron used to produce large coils of galvanized wire can be divided into two classes. A metal produced directly from iron ore and iron smelting, consisting of iron oxide, silicon dioxide, and other miscellaneous stones. When this ore is specially refined into metal iron, carbon, silicon, manganese, and other elements are mixed in, so that the refined material is called general pig iron, is also for the initial grade of the material.
If the surface of galvanized wire is black and the galvanized layer is thin and uneven, the galvanized wire is partly because the inventory storage time is longer, but also because the production technical requirements of galvanized wire do not meet the standard and lead to the quality problems of galvanized wire. According to the use of galvanized wire is different, galvanized wire has soft and hard, then the galvanized wire used for binding requires the flexibility of galvanized wire is better, the flexibility of galvanized wire is good, and it can be easy for workers to operate.
Hook fence is made of hook fence for the net surface of the protective net, barrier grid. Material PVC wire, stainless steel wire, good low carbon steel wire, galvanized wire, iron wire hook mesh is made of hook mesh machine for various materials of wire hook knitting, can be divided into two kinds of folding, screwing lock.
