Hot-dip galvanizing Yuzhnouralsk

The most popular material in construction and industry is metal. The task of protecting the part from corrosion becomes a priority. There are several ways to strengthen the steel. The oldest – dipping articles in molten zinc.

Today, a national standard to regulate the process. In accordance with GOST, Yuzhnouralsk produces hot dip galvanizing in several steps.

The first important step is preparation. Only on smooth, cleaned product zinc will go efficiently. First of all, any surface is cleaned. Acid and alkali remove oils or synthetic compounds from the part. It is the nature of pollution that determines the choice of reagent. The procedure is carried out at a temperature of 60-80 degrees. After degreasing may remain a small amount of foam from the reagent or oil. To remove them, the item is washed.

Etching is the next procedure. On the degreased surface are rust, scale. For removal, hydrochloric acid is used in a concentration of 120-210 g / l and a temperature of 20-25 degrees. It is the acid that makes the surface smooth and shiny by removing iron chloride. It is worth remembering – hydrochloric acid dissolves not only rust, but also the surface of the steel. It is recommended to rinse the item thoroughly.

Fluxing, or applying a solution of flux, is necessary to remove iron oxide. Flux is used quite concentrated (400-600 g/l), the temperature is maintained at 60 degrees.

The final stage of preparation is drying the product. Often the drying time significantly exceeds the galvanizing time. On the non-dried metal, the remaining water evaporates, causing micro-explosions. This is fraught with "bare" areas, uneven coverage and poor adhesion.

Hot-dip galvanizing Yuzhnouralsk

Hot-dip galvanizing in Yuzhnouralsk is carried out using a special ceramic bath filled with zinc heated to 450 degrees. Lower in zinc and lift the item from the bath should be inside the spinning drum. Soak in zinc should be 3-10 minutes. After lifting, the formed slags are removed.

With proper galvanizing metal construction will last up to 50 years. The method of protection of parts used in urban and private construction. Be sure to handle the support of power lines, bridge supports, pipes, stair railings. Household utensils also need to be strengthened with zinc-metal utensils, tanks or basins.

It is noteworthy that the zinc treatment retains thermal conductivity, electrical conductivity. The technology involves the gradual penetration of zinc into the metal structure (2 mm. per year). Upon receipt of mechanical damage to the surface will regenerate itself at the expense of the zinc.
