welded mesh fencing price check

Large roll galvanized wire welding net is made of high quality galvanized wire welding net, wire through the current, after mutual melting, strong connection point, and the formation of metal mesh. In the use of galvanized iron wire to find the thickness and soft and hard to the size of flowers, weight and softness corresponding to the degree, too soft florets to use fine wire, and heavy flowers, flowers with thick stems to use thick wire.

Paint on the galvanized layer, the binding force between each other and the baking temperature of the paint has a great relationship, after galvanized coating alkyd paint, adhesion is no problem. Galvanized amino paint, paint adhesion is not good. Do two bottom two surface, adhesion is ok, if the two bottom two surface to two bottom three surface, that is, more paint, more baking once, again test adhesion is very poor, poor to the paint from the galvanized layer of pieces torn off.

3, reduce the bivalent iron ion in the plating aid used for hot plating wire, reduce the formation of zinc slag

If the zinc coating is good, but in 3% nitric acid when the light, the coating has dark shadow, passivation occurs when the film is brown, may be caused by foreign metal impurities such as copper or lead in the galvanizing liquid. When problems occur in the process of galvanizing large coil galvanized wire, the temperature and current density are checked first, and then the content of zinc and sodium hydroxide in the plating solution is measured and adjusted through the analysis of the plating solution. Whether DPE content is low can be determined by hull cell test.
