Modern construction and industry can not be imagined without equipment, metal parts. The material requires care and protection from unwanted environmental influences. For several centuries, the method of immersing the steel element in hot zinc and creating an additional protective layer has been popular.
Hot-dip galvanizing technology in Novosibirsk is especially popular due to its numerous advantages:
The cost of the treatment procedure is also important. In comparison with similar methods aimed at strengthening the metal, galvanizing remains the most budget. The procedure is quite simple – the only difficulty may arise in preparing the product for immersion in the chemical composition.
The preparatory stage of the method of hot-dip galvanizing Novosibirsk offers to perform in several steps. Be sure to degrease the surface, remove oil, synthetic compounds. This can be done with the help of chemical reagents – alkali, acid. After using the chemical product should be thoroughly washed. The remaining chemicals can damage the materials.
For washing should be an important step-etching. With the help of hydrochloric acid, it is necessary to remove the remains of rust, scale. The product is treated with an acid that dissolves iron chloride from the surface. It is the acid that provides the parts with a smooth surface, which is important for good adhesion of the protective melt to the metal structure. Input substances-inhibitors help prevent the hydrogenation of steel. Subsequent rinsing removes residues of salts.
The last step in preparation for dipping – fluxing. Coating the part with a solution of flux has two main functions: surface cleaning, film formation and ensuring good wetting when bonding with zinc.
After drying the fluxed product, it is immersed in a bath filled with hot zinc. Withstand should be 3-10 minutes. Immersion and removal occur exclusively with the use of a rotating drum to avoid uneven application of zinc composition.
With the correct procedure, the life of the metal structure will be up to 50 years. No additional repairs or maintenance will be required.
