The cold-rolled steel plate used in the all-steel fume hood is also an iron plate in the popular sense. The main components of the steel plate or iron plate are iron and carbon, which means it will rust. Iron and oxygen can easily produce iron oxide or ferric oxide, ferric oxide, etc.
Consumers need to pay attention, some manufacturers sayAll steel fume hoodIt is non-rusting, and there is no problem in acid and alkali experimental environments. It can be said that high surface temperature and electrostatic spray powder can only play a protective role, but over time, the acid and alkali in the environment are severely volatilized, or indoor humidity will affect the use of the fume hood. Therefore, the editor recommends that customers use stainless steel or PP fume hoods if there are many acid-base experiments.
It is hoped that consumers will not be greedy for cheap when purchasing products, and when purchasing products, they should choose laboratory manufacturers with larger scale and better reputation.
