Some raw materials in the production of unstable processing, the wire itself will exist burr, surface small pits and other local defects. Galvanized steel in galvanized, generally should pay attention to the galvanized layer protection time of galvanized wire, and the thickness of galvanized layer has a great relationship. Generally speaking, when the main gas is relatively dry and used indoors, the galvanized layer thickness of galvanized wires is only 6-12μm, and under relatively harsh conditions, the galvanized layer thickness of galvanized wires needs 20μm, and can be predicted to reach 50μm.
Specific requirements for the safety of galvanized wire production: clean up all tools and other objects that hinder production in the galvanized wire production environment. Operators in the pickling process, pay attention to the action should be careful, not careless, into the pickling tank must be handled lightly, to prevent splashing on the body. When adding acid, the acid must be slowly poured into the water. It is forbidden to pour the water into the acid, so as to prevent the acid from splashing out and hurting people. Do not hurt yourself or others.
The welding between low carbon steel, low alloy steel, medium carbon steel, alloy steel and the same kind of metal materials or dissimilar metal materials can be realized. The weld has good comprehensive mechanical properties, tensile strength can reach more than 400MPa.
Its wire diameter specifications include: 8#-24#, with thick coating, corrosion resistance, strong coating and so on. And according to the special needs of users, according to industry standards to provide various specifications of galvanized wire. Low carbon steel wire is called galvanized iron wire after drawing and galvanized, so galvanized wire products have certain characteristics. In order to better let galvanized wire play an effect, in the process of galvanized wire, generally according to customer needs to control the thickness of galvanized wire zinc layer, so that galvanized wire can meet the needs of customers.
Hook mesh from the point of view of weaving quality inspection requirements, hook mesh wire and silk staggered can not loose, the whole piece of hook mesh can not loose deformation. Of course, if the customer special requirements out of the net, showing loose phenomenon can not blame the production side. Whether the mesh meets the specification requirements and the wire diameter meets the wire diameter.Application range of hot dip galvanizing: because of the thicker coating, hot dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for iron and steel parts in harsh working environment. Hot dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, power transmission, shipbuilding and other industries, in the agricultural field such as irrigation, greenhouse and construction such as water and gas transmission, wire casing, scaffolding, Bridges, road guardrail and other aspects, has been widely used.
Large roll galvanized wire phosphating film is dark gray to black gray, the thickness is generally 5-20μm, has better corrosion resistance in the atmosphere. Membrane is a microporous structure, strong adsorption ability to paint, such as used as paint bottom, corrosion resistance can be further advanced. Metal oxidation treatment: Add steel products to NaOH and NaNO2 mixed solution, heating treatment, the surface can form a layer of thickness of about 0.5-1.5μm blue oxide film, in order to reach the purpose of steel corrosion prevention, this process is called blue treatment, referred to as blue.
The difference between them can be so divided, the amount of zinc on the surface of the high zinc thorn rope is about 5 times that of the general zinc thorn rope, which greatly extends the time of rust prevention ability. In the appearance of the two products are silver and white at the same time the metal texture is better, for the difference between the two products if it is not good to distinguish, but for long-term work experts can be able to distinguish the two at a glance.
Another way is to have special equipment for measuring, which is expensive and impossible for ordinary users to buy. The last method is that there is a hierarchy gap in the light sense of the barbed rope, the general zinc barbed rope is more bright and the high zinc barbed rope is slightly darker, so customers do not think that the more beautiful the appearance of the product is good quality. 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.
1. Electroplating process control
Cold plating is a physical treatment method, the zinc is simple and uneven, the amount of zinc is also less than in the corrosion and rust prevention and chemical disposal of hot plating; The amount of hot zinc plating is relatively thick, the surface of the disposal is flat on average, and it is not easy to fall off. A layer of alloy composed of zinc and metal has very strong oxidation ability, and there is a layer of pure zinc on the outside of this layer of alloy, which is why hot plating is thicker and stronger than cold plating. Under the condition of high degree of natural recovery, galvanized hook net can play a very good maintenance effect on the environment, it is not afraid of wind and rain, it is the battle machine in the hook net, much stronger than the dip plastic hook net.
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.
The characteristics of hexagonal net: solid structure, flat surface, with good corrosion resistance, oxidation resistance and other characteristics: used for raising chickens, ducks, geese, rabbits and zoo fences, mechanical equipment protection, highway guardrail, sports places Seine, road green belt protection net. The screen in the production of box shaped container, with stone filled with cages, can be used to protect and support seawall, hillside, road and bridge, reservoir and other civil engineering, is a good material for flood control and flood resistance, namely (stone cage net, stone cage cage).
