Galvanized wire cannot be used without maintenance. Large rolls of galvanized silk should be coated with oil, and the fiber core should be dipped in oil. The oil is required to protect the fiber core from decay and corrosion, moisten the fiber with iron wire, and lubricate the wire rope from the inside. The surface is coated with oil so that the surface of all the wires in the rope strand is evenly coated with a layer of anti-rust lubricating grease. For the mine rope with large friction and mineral water, it should be coated with black oil grease with increased wear and strong water resistance. It is coated with red oil with strong film and good rust resistance, and it is required to have a thin oil layer, which is easy to keep clean during the operation.
Galvanized wire coating is galvanized, aluminum plated, coated with nylon or plastic, etc. Zinc plating is divided into thin coating after steel wire plating and thick coating after steel wire drawing. The mechanical properties of thick coating are reduced compared with smooth steel wire rope, and it should be used in severe corrosion environment. It is more corrosion resistant, wear resistant and heat resistant than galvanized wire rope. It is produced by plating before drawing. Coated nylon or plastic wire rope is divided into two kinds of coated rope and coated stock after the rope.
Through the maintenance of galvanized wire, it can not only greatly extend its service life, but also improve its efficiency in the daily use process. Galvanized wire and general wire is very different, general wire is cheap, and because the iron is not very stable, easy to rust in the wet place, so the stability is not very good, the life is not very long. Galvanized wire is coated with a layer of stable zinc on the outside of the wire, and the zinc layer is used to protect the wire and make the service life of the wire longer.
In the production of galvanized wire, the wire should be pickled. Pickling is to use some acid mist or acid to wash away some oxides on the surface of iron, that is, rust, and some other corrosion substances, to achieve the purpose of cleaning iron, so that zinc will fall off when galvanized. When pickling, we should pay great attention to the fact that acid is very corrosive, so when adding acid, we must pour acid into water, and it is along the wall of the cylinder, not a splash down, so as not to cause splash.
Remember the order of pouring acid, acid into water rather than water into acid, water into acid will cause splashing and boiling, when pouring acid must wear protective glasses, must ensure that there are no non-professional onlookers, so as not to cause some risk of splashing acid.
