查询词典 initial condition

This paper mainly studies effect and influence factor that typical corrosive medium (muriatic acid, vitriol, nitric acid, sodium hydroxide, sodium chloride etc.), consistence and condition temperature acts on the material coated on castiron centrifugal interface (PFEP, PPS, CPE, remodeled epoxy). It is studied that powder electrostatic spray, suspend fluid spray, suspend fluid electrophoresis underside coat etc. technics influences on coat quality coated with above four anticorrosive material. The property analysis is done that above four anticorrosive material and three coat technics adapt to centrifugal pump frame and running dynamic condition. In addition, the effect is introduced that castiron centrifugal coated anticorrosive material is used in coal water with alum.
