When galvanized wire is galvanized, it is generally necessary to pay attention to the following problems: the duration of the protective effect of galvanized wire is greatly related to the thickness of the coating. Generally speaking, in the dry main gas and in indoor use, the thickness of galvanized wire galvanized layer only 6-12 μm “, and in harsh environmental conditions, galvanized wire galvanized layer thickness needs 20μm “to B height up to 50μm”. Therefore, the environmental impact should be considered when choosing the thickness of galvanized layer. Galvanized wire in galvanized, pay attention to the above problems, can be well galvanized, to ensure the quality of galvanized wire.

2. Eliminate caked zinc residue on zinc liquid surface

Because the coating obtained is thicker, hot-dip galvanizing has very good protective function than electric galvanizing, so it is an important maintenance coating for iron and steel parts in strict working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transportation, shipbuilding and other occupations. In the field of agriculture, such as pesticide irrigation, greenhouse and construction industry such as water and gas transportation, wire casing, scaffolding, Bridges, highway guardrail and other aspects, it has been widely used in these years.

The main customers of the thorn rope factory are still targeted at farms and plantations, because the demand for thorn rope is often very large.

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.

The impregnated hexagonal wire mesh will lose its original characteristics after corrosion, and will change in shape, color and mechanical properties, resulting in equipment damage, pipeline leakage, etc., specifically, it is easy to break and lose the original protection function. Usually there are three kinds of metal corrosion: physical corrosion, chemical corrosion, electrochemical corrosion, corrosion in addition to the chemical properties and organizational structure of the metal itself, but also related to the surrounding medium, such as wet environment than dry environment easy corrosion, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the corrosion of impregnated hexagonal wire mesh, prolong the service life of products.

The management system of the rinsing water after the steel wire pickling should be regularly and regularly discharged after the rinsing water, and the rinsing water should be kept clean and low acid value as far as possible. The pH control is more appropriate. The concentration of plating aid should not be too high. Hot plating wire must be added ammonium chloride and zinc chloride according to the data of laboratory analysis, and the specific gravity of the composite solution is controlled in the range of 50~80g/L. The addition of ammonium chloride or zinc chloride raw materials without the results of laboratory analysis shall be subject to criticism and education, and economic treatment if necessary.

Bridge protection system generally do not need to install special drainage system, the use of hexagonal mesh gabion cage, the filling is selected stones, the stones are not easy to wear, and between the stones and stones will retain some space, so it is very good to meet the drainage requirements.

The quality of hot-dip galvanized barbed wire is only the zinc layer attached to the surface of the wire, and with the chemical reaction, the zinc layer on the surface will gradually lose its role because of the oxidation reaction, which is more prominent in the humid environment. And because the use of rusty wire after all, it is said that the quality of hot-dip galvanized barbed wire is certainly not up to the level of stainless steel barbed wire.

A pet carrier can be used as an indoor or outdoor pet house. The dog cage is equipped with a fixed food basin and water fountain, and the foot plate pet cage rubber pad has bayonets on four sides to be splintered. It can be spliced, cut and disassembled according to the size of the cage. It is convenient and easy to clean. It can solve the problem of pinching the feet of the puppies in the ordinary cage and prevent the puppies from causing adverse reactions in the development. The dividers are breathable and comfortable, and can be used as heat shields for pets in summer. A puppy with small feet, no feet, no pinching.
