Illustrations are hydrochloric acid and hydrobromic acid, made from halogen-containing plastics and fireplace retardants, hydrofluoric acid unveiled by pyrolysis of fluorocarbon fireplace suppression brokers, sulfuric acid from burning of sulfur-that contains supplies, nitric acid from large-temperature fires the place nitrous oxide gets fashioned, phosphoric acid and antimony compounds from P and Sb based mostly fireplace retardants, and a lot of Some others. These corrosion is just not significant for structural resources, but fragile structures, Specially microelectronics, are strongly affected. Corrosion of circuit board traces, penetration of aggressive substances with the casings of areas, along with other outcomes could potentially cause a right away or gradual deterioration of parameters or even premature nuso (and sometimes delayed, given that the corrosion can development over very long time) failure of kit subjected to smoke.
