摘要

High-performance protective coatings often fail in the severe environment of the headspace in domestic wastewater collection and treatment systems.Coating failures are attributed to many factors,including extensive permeability to hydrogen sulfide gas(H2S)and other corrosive gases present.Although the chemical and physical properties of coating systems can be determined in the laboratory,this is not the case for the effects of environmental conditions,such as exposure to severe environments within wastewater headspaces.
