Due to the influence of production process or other factors, the zinc layer of galvanized wire products will be different to a certain extent, especially ordinary galvanized can not reach the beauty of electric galvanized, ordinary galvanized wire zinc layer is mainly for anticorrosion and corrosion prevention. Large volume galvanized wire products refers to the use of high quality low carbon steel, after drawing forming, pickling rust removal, high temperature annealing, hot dip galvanized, cooling and other processes, some galvanized wire products are made of iron wire galvanized.
Pay attention to safety in line collection and operation, others without the consent of the monitor, Ben have to get on the bus operation. The reels should be placed lightly, stacked firmly and neatly, not more than 5 reels. Direct contact with acid and alkali must be prohibited. When the acid fog exceeds the specified target of the state, measures should be taken to control it in time, otherwise production is not allowed.
The application of black iron wire in the process is mainly through the hot metal billet rolled into 6.5 mm wire rod, and then put it into the wire drawing device into a different diameter line, and then gradually reduce the aperture of the wire drawing disk, cooling and annealing, coating and other processes, made into a variety of different specifications of iron wire, this kind of iron wire and ordinary black iron wire compared, will be softer, Softness is also very uniform, color is consistent, widely used in the construction industry, mining, chemical industry, welding mesh, welding hanger, reprocessing industry.
Generally speaking, in dry main gas and indoor use, the thickness of galvanized coating is only 6-12μm, but under poor environmental conditions, the thickness of galvanized coating is 20μm, can reach 50μm. Therefore, environmental factors should be considered when choosing the thickness of galvanized layer. Galvanized layer after passivation treatment, can naturally form a layer of bright, beautiful color passivation film, can obviously improve its protective function, decorative.
It’s not clear why friends would want to use building nets for floor heating. What is its advantage in the floor heating project, the role of steel wire mesh is convenient for construction. Building mesh can better fix the pipe, conducive to the construction of the floor, improve efficiency. Anti-cracking function. The building network can improve the bearing capacity of the foundation of the insulation board, the thicker the diameter of the building steel wire, the greater the bearing capacity, effectively prevent the appearance of cracks and cracks of steel wire mesh can improve the thermal shrinkage and shrinkage of cement, strengthen the tensile strength of cement, improve the quality of the heating project.
The production process of large rolls of galvanized wire is a level of drawing, through the mold into a slightly smaller diameter than the original. And so on down to the desired length. One pull is not desirable, must be numbered, from coarse to fine is dependent on metal ductility. If it changes too much it just breaks. After drawing to a certain diameter, galvanized, so that the finished product.
Removal of surface-active substances by activated carbon matting. Or make the bubble unstable according to overworry, these are all reasonable countermeasures; Other strategies should also be used to minimize the amount of surfactant taken in. The introduction of organic matter can make the electroplating process speed drop sharply. Galvanized iron wire blackening can be effectively prevented, such as: the work site to keep dry, reduce and do not use chemicals, operators with clean gloves and so on. In addition, hot dipping zinc factory can be required, after dipping zinc must be passivation treatment, passivation treatment of zinc has a better anti-discoloration effect, can effectively prolong the discoloration time, the combination of the two, discoloration should be able to solve. Galvanized iron wire has good toughness and elasticity, the amount of zinc can reach 300 g/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance.
