- There are many kinds of zinc plating solution, which can be divided into plating solution and no plating solution according to its properties. The galvanized liquid has good dispersion and covering property, the coating crystal is smooth and fine, the operation is simple, the application range is wide, and the long-term use is in the production. However, due to the toxic substances contained in the plating solution, the gas escaping from the plating process has great harm to the health of workers, and the waste water must be treated strictly before discharge.
- 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.
- Decorative hook mesh also has flexible characteristics can be used in different fields according to the needs of designers. When using hook mesh in corrosive environment, we must attach great importance to the selection of hook mesh parts materials. Now the hook mesh is often used in breeding fences, captive animals, protective gardens, etc., the wind and sun surrounding environment is difficult to ensure its life, some hook mesh in use for a period of time, due to exposure to the sun and humidity, will appear welding phenomenon, easy to shorten the service life.
