    What are the factors that affect the resistivity of insulating materials

    (1) Temperature. As the temperature increases, its resistivity decreases exponentially. This is because when the temperature rises, the thermal motion of the molecules intensifies, and the average kinetic energy of the molecules increases, which increases the probability that the kinetic energy of t... read more

    What are the components of epoxy resin anticorrosive materials

    One is epoxy resin, which is a general term for polymers containing epoxy groups. It is mainly suitable for media that is not very corrosive. It has outstanding alkali resistance and is also resistant to corrosion by general acids (except hydrofluoric acid). The second is the curing agent of epoxy r... read more
