reinforcing wire mesh

Strictly control the pH value of large roll galvanized wire bath, research shows that the size of the bath pH value directly affects the quality of steel wire coating, improper control of pH value will cause loose coating. When the pH value is greater than 3, the steel wire coating has burr caused by fine dendrites, and the surface is not smooth. The current density is strictly controlled. From the microscopic morphology, the higher the current density, the larger the zinc layer grain deposition, the less dense the corresponding zinc layer.

Packing is also very important. The cut wire should be bundled and tightly packed with plastic film, and then placed in a regular box. The whole box should be filled and sealed. It is better not to have half a box.

Pure zinc is more stable in dry air. In moist air or water containing carbon dioxide and oxygen, the surface will generate a layer of basic zinc carbonate based thin film layer, which can delay the corrosion rate of zinc layer. Comparison of corrosion resistance of zinc coating in aqueous solution of acid, alkali and sodium chloride; It is also resistant to corrosion in atmospheres containing carbon dioxide and hydrogen sulfide and in oceanic atmospheres; In high temperature and high humidity air and contain organic acid atmosphere is small, galvanized layer is also easy to be corroded.

Maintenance is indispensable in the use of galvanized wire. Large coils of galvanized silk should be coated with oil, fiber core immersion oil, oil is required to protect the fiber core is not rotten, not rust, wire moisture fiber, and from the internal lubrication wire rope. Surface coating so that all wire rope strands in the surface, are evenly coated with a layer of rust-proof lubrication grease, which for friction lifting and mineral water large mine rope, to be coated with grinding and water-resistant black oil grease. Coated with red oil with strong film and good rust resistance, it is required to have a thin oil layer, which is easy to keep clean during operation.
