History of hot dip galvanizing method
79 years BC.
Initial data on the use of zinc has been approximately dated to the year 79 BC. The first time the element was involved in the construction field. The detected records are considered to be the occurrence of galvanization.
The initial fixed chronicle of galvanizing — Paul Jacques Malouin, a chemist from France, demonstrated in the Royal Academy of Sciences separate experiments that were associated with the finish of iron with melted zinc (galvanized iron).
Luigi Galvani, an Italian physicist and doctor, studied the chemical course, which is made between different alloys during the experiments, according to electrophysiology.
Alessandro Volta helped galvanize when an Italian physicist discovered the presence of electrical potential between the two alloys, forming the most basic chemical resource of the current.
M. Faraday noted the" sacrificing " property of zinc during experiments with this element and salted water.
The French physicist C. Sorel obtained a patent for galvanizing the movement.
Industry of Britain began to use about 10’000 tons of zinc every year with the aim of making the treated zinc steel.
The US is significantly behind in the development from Britain. In the United States of America the very first galvanizing plant began its work only at the beginning of 1870. At that time, the metals were dipped into a tank of melted zinc by hand.
Progress in the fields of metallurgy and bath production technology has many times raised the effectiveness of galvanizing/galvanizing and the reliability of the resulting coating.
At the moment, about 10 million tons of zinc are consumed every year around the world. For hot-dip galvanizing of steel spent most of 2 million tons (for hot processing of metals) and approximately 6 million tons for the continuity of the progress of the oxidation. In any large area in which steel is used, one way or another can be faced with galvanization. Chemical, machinery, motor transport, municipal, pulp and paper-these are only some of the areas that have historically been very dynamically used by galvanizing to protect against rust. They continue to use some technological processes and today. The galvanizing method contains a true and growing history of success in numerous applications around the world.
