There are three methods to detect the thickness of zinc layer of galvanized wire: weighing method, cross section microscopy method and magnetic method, among which the first two experiments will cause certain damage to galvanized wire, including the length of galvanized wire and the reduction of dosage. The general detection of galvanized wire galvanized layer is detected by magnetic method, which is also a more intuitive and convenient method. The standard of galvanized layer thickness is related to the wire diameter of galvanized wire. The larger the wire diameter of galvanized wire, the thicker the galvanized layer is. It is the thickness of galvanized layer and cast iron after centrifugal separation.

1, stress relief before plating where the maximum tensile strength is greater than 1034Mpa key and important parts before plating should be at 200±10℃ stress relief for more than 1 hours, carburizing or surface quenching parts should be at 140±10℃ stress relief for more than 5 hours.

Hot wire mesh in the building wall engineering mainly played the anti-crack effect, inside and outside the use of specifications are not the same. Hot dipped wire material choose low carbon wire, through automation welding precision machinery processing after forming, surface treatment by zinc immersion process, galvanized barbed wire surface smooth and tidy, uniform structure strong, the overall performance is good, even if the local cutting or under pressure will not loose phenomenon occurs, it is the iron mesh strong anticorrosion performance in one of the widely used net class.

Galvanized wire is processed from low carbon steel wire rod, after drawing forming, pickling rust removal, high temperature annealing, cooling and other processes. Galvanized wire is widely used. Electroplating temperature should be controlled at 30 to 50℃. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used.

Dog cage mainly by welding, spraying, injection molding, surface treatment, electroplating dog cage is made of high quality steel wire, dog cages are with plastic and plastic surface treatment, electrophoresis, chrome plating, galvanized, imitation gold, etc., according to the customer request processing, respectively, also can be customized to sample, dog cage assembly of compact structure, neat and beautiful appearance, make folding and remove the cage is more convenient and quick, won’t take up too much space.

Temporary rust prevention is to prepare for the completion of the mission of the protective layer to be removed. The methods include: cajoling corrosion inhibitors, coating antirust oil, peeling molecular compound plastics, drying air, vacuuming, etc. Change the internal structure of the metal: new chromium, nickel and other alloy elements made of stainless steel, but the alloy is not much, expensive, difficult to produce widespread application.

Most people in addition to pay attention to the price of barbed rope, many people for hot-dip galvanized barbed rope or cold galvanized barbed rope will have questions, in fact, these two products, the price difference is not very big, so how to choose hot-dip galvanized barbed rope and electric galvanized barbed rope?

Cold galvanized by electrolytic action to metal and other materials surface attached to a layer of metal film, so that the surface of the material uniform texture, anti-corrosion wear, appearance is more beautiful. Hot dip galvanized coating is thicker, generally 30-60 microns, coating corrosion resistance is higher. Suitable for outdoor work of steel parts, such as highway fences, power towers, large size fasteners and other “rough” workpiece long-term rust prevention.

Zinc is a silver-white metal, brittle at room temperature, soluble in acid and alkali, known as amphoteric metal. Pure zinc is more stable in dry air, and small in humid air or water containing carbon dioxide and oxygen. A thin film layer of basic zinc carbonate will be formed on the surface, which can delay the corrosion rate of zinc layer. The corrosion resistance of galvanized layer in aqueous solution of acid, alkali and sodium chloride is relatively strong. It is also not resistant to corrosion in atmospheres containing carbon dioxide and hydrogen sulfide and in Marine atmospheres; In high temperature and high humidity air and containing organic acid atmosphere is small, galvanized layer is also easy to be corroded.

Some customers are more concerned about quality problems, so for the service life is more important, barbed rope factory will generally recommend the use of high zinc barbed rope or stainless steel barbed rope.
