Corrosion degradation of metal materials in the fermentation industry environment.Peer-reviewed article

A vast majority of machine works is made of steel materials and a fermentation industry does not seem to be an exemption. As there are plants with a high humidity and a heterogenic temperature in the fermentation industry, a large degradation due to the corrosion occurs. It is a gradual process, which in its graduation might cause a shutdown of the whole production line. The aim of this contribution was to make recommendations of an appropriate corrosion protection applicable in the fermentation (brewery) industry, based on the results of tests of two anticorrosion systems. In the laboratory simulating normal service conditions, there was tested a synthetic single- layer paint (organic protection) and a zinc-coating layer (inorganic protection). In order to increase corrosion pressure, both anticorrosion systems were destructed by microcracks which approximate a normal destruction of coating compactness which normally occurs in service conditions.A vast majority of machine works is made of steel materials and a fermentation industry does not seem to be an exemption.
