The use of galvanized wire is inseparable from maintenance. The large roll of galvanized silk should be coated with oil, the fiber core is dipped in oil, and the oil is required to protect the fiber core from decay and rust, the wire moistens the fiber, and lubricates 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, among which the rope used in the mine with large friction lifting and mineral water should be coated with black oil grease with increased wear and strong water resistance. It is coated with red oil grease with strong film and good rust resistance, and requires a thin oil layer, which is easy to keep clean during operation.
Galvanized wire coating is galvanized, aluminum plated, coated with nylon or plastic, etc. Galvanized steel is divided into thin coating after steel wire plating and thick coating after steel wire drawing, the mechanical properties of thick coating are lower than that of smooth steel wire rope, and should be used in serious corrosion environment. Aluminized wire rope It is more resistant to corrosion, wear and heat than galvanized wire rope, using the first plating and then drawing method of production. The wire rope coated with nylon or plastic is divided into two kinds: the coated rope and the combined rope after the coated strand.
Through the maintenance of galvanized wire, it can not only greatly extend its service life, but also improve its efficiency in daily use. The difference between galvanized wire and general wire is very big, general wire is cheap, and because the iron is not very stable, it is easy to rust in wet places, so the stability is not very good, and 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.
When producing 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 the iron, that is, rust, and some other corrosive substances, to achieve the purpose of cleaning the iron, so that the zinc will fall off when galvanized. When pickling, we should pay great attention to the acid is very corrosive, so when adding the acid, we must pour the acid into the water, and it is along the cylinder wall, not to pour it down at a time, so as not to cause splashing.
Remember the order of pouring acid, acid into water rather than water into acid, water into acid will cause splashing and boiling, be sure to wear protective glasses when pouring acid, and be sure to ensure that there are no non-professional onlookers, so as not to cause some danger of splashing acid.
