Usually, there are three kinds of metal corrosion: physical corrosion, chemical corrosion, electrochemical corrosion, corrosion in addition to the chemical properties and organizational structure of the metal itself, but also related to the surrounding medium, such as wet environment is easier to rust than dry environment, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the customized corrosion of hexagonal guardrail and extend the service life of the product.
The use of packaging galvanized wire with the development of industry and agriculture is also expanded accordingly. Therefore, galvanized silk commodities have been widely used in industry (such as chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transportation, shipbuilding, etc.), agriculture (such as irrigation, heating houses), construction (such as water and gas transportation, wire casing, scaffolding, houses, etc.), Bridges, transportation, etc., in recent years. Because galvanized silk products have beautiful surface, good corrosion resistance and other characteristics, its use is more and more extensive.
The application of electric welding net is more widely, at present it has replaced the use of other parts of the wire mesh, the cost of electric welding net is lower, the production speed is very fast, so it is very popular. Welding net galvanized before the need for processing is recrystallization annealing, because the welding net must maintain a no oxide and no other impurities of pure iron active surface, if you can not keep its surface clean will lead to a bad galvanizing effect, galvanized layer and iron material is not closely combined, so this step is necessary.
There is also a scaly or boride film or oxide. To remove the photosynovium or oxide commonly used methods are: lead grease removal method, acoustic cleaning method, alkali washing or pickling electrolysis grease to oxide method, these methods in the use of gas or steam harmful to human body, pollution, not environmental protection.
Different from common zinc barbed rope, high zinc barbed rope surface zinc content is very high can reach 6-8 times of the former, so there is a great advantage in the service life, ordinary products begin to corrosion three to five years while the latter will take longer to change. Stainless steel barbed rope is in material protection so durability is also better, these two products are long service life, but in terms of high price.
Wire mesh first welding after galvanized is through the end of welding and then the company to produce wire mesh wire mesh steel mesh construction mesh, floor heating mesh galvanized or hot dip galvanized. First galvanized after welding is to change wire mesh, after the end of welding can see the solder joint; The two processes are different in price. The cost of plating after welding is low, the appearance is smooth, and the cost of plating after welding is high, and it is not easy to rust.
Flood control and flood is good information. Can also be used for handicrafts manufacturing, machinery and equipment of transport network mountain beautification network – high strength wire grille (hook flower net, rhombus net) the use of mountain flowers network protection principle, hook flower net, mesh uniform, flat surface, weaving concise, crochet, beautiful generous, wire mesh, mesh with wider picture, diameter of thicker, not easy corrosion, taking a long, and strong usefulness.
Zinc pot workers should be determined to do duty and responsibility. Do not leave the post without leave, always observe the change of hot plating wire galvanized layer, and according to the analysis results, master the asbestos block gap friction, how long it takes to press, replace the pressing face; Adjust the working face; Until all four faces of the asbestos block are used up, maintenance workers can continue to use the asbestos block after repair when necessary to reduce the consumption of asbestos block.
