The technology of processing metal objects with hot zinc was invented in France several hundred years ago. Gradually the knowledge spread to the East, closer to the German territories, and now it is actively used in Russia. Safety of metal structures from electrochemical corrosion is a priority for any industrial production.
Technology hot-dip galvanizing Izhevsk mastered several decades ago. Now the city can provide a full range of services for the protection of steel equipment.
The full cycle of work includes several stages of the operation. The item is prepared for immersion in a hot chemical composition. It is cleaned of oils and residues of synthetic compounds, washed. The next stage of cleaning is called etching. With the help of acid, rust and scale are removed. Then rinsing is required again. The final step in the preparation of the metal structure will be fluxing. The part is covered with a special composition having two main functions - additional sterilization and formation of a protective film on the surface. The coating provides better adhesion of zinc to the metal.
The prepared part can be lowered into the molten bath. The bath is filled with zinc solution (not less than 98%), heated to 450 degrees. Get a smooth coating when immersed metal element can be, if you put the item inside the rotating drum. Keep the drum in zinc is recommended not more than 10 minutes. This time is enough to bond the solution to the metal. It is necessary to lift also as there was a dive-in a rotating drum. The thickness of the layer depends on the lifting speed. Low speed provides a thin layer of zinc on the product.
During the dive on the parts formed excess zinc, which must be removed. The item is dried inside a special device.
Proper execution of the operation ensures high quality of the result, fully compliant with GOST. If in doubt, it is easy to check the thickness of the mixture and the density of the coating. This can be done purely mechanically (you will need a hammer or a special steel cutter) and use the equipment designed for this.
In case of full compliance with the requirements of GOST, the use of hot dip galvanizing in Izhevsk has significant advantages:
The use of this method made it possible to achieve high results in urban construction, the production of household appliances. The products have good performance.
