Hot-dip galvanizing Chelyabinsk region

The main enemy of metal is corrosion. Since the mid-18th century, scientists are looking for a way to protect steel parts from the effects of water, to increase the service life of products. Today, the most popular method is galvanizing of metal structures.

A qualitative result can be obtained, taking into account all the recommendations of the state standard. Hot dip galvanizing Chelyabinsk region has the ability to carry out in accordance with the requirements of GOST – in several stages.

The first stage is preparatory. Dirt is removed from the surface of the part. With the help of acid or alkali to clean the metal from the oil, synthetic compounds. It is important to wash the steel part well after cleaning – there may be foam from reagents on the surface, fat, preventing the smooth application of the mixture.

Etching is the next procedure. Hydrochloric acid concentration of 120-210 g / l cleans the product from rust. The acid can corrode the scale, but it is also harmful to the surface of the metal. For etching should be thoroughly washed.

The final stage of preparation is fluxing. A concentrated solution of flux (400-600 g/l) is applied to the part at a temperature of 60 degrees. Flux creates a film on the steel, which allows the metal and zinc to better grasp.

The immersion itself is impossible without a rotating drum. It is the drum that provides uniformity of corrosion protection. Withstand the drum with the part in zinc should be 3-10 minutes, after which it is necessary to remove the formed slags.

Despite the widespread use of hot-dip galvanizing in the Chelyabinsk region, not every steel can be treated with zinc. The procedure is only valid for low carbon steel. To form and as the details require a lot:

  • there should be no chipping, metal shavings, graphite, marking paint, pores, cracks;
  • too narrow threads are most exposed to corrosion due to the difficulty in applying the protective melt. It will have to be processed further;
  • drums, coils, plugs in pipes, boxes can prevent the application of zinc;
  • the size of the part is limited by the size of the bath in which zinc is poured. Too much detail may not fit. Too small and thin detail makes no sense to additionally cover with zinc.

In case of compliance with all requirements and competent implementation of the procedure, the metal structure will significantly increase its service life – up to 50 years. Repair or maintenance will not be required – zinc penetrates deep into the metal structure. Small damage occurring on the surface can be easily eliminated. The surface has the ability to independently recover.
