Problems solved by technology

[0002] It is well known that the electrostatic conductive coating is a functional coating with the ability to conduct current and eliminate accumulated charges. The electrostatic conductive coating used in petrochemical storage tanks is to avoid accidents such as explosions and fires caused by the accumulation of charges. With the application of electrostatic conductive coatings , petrochemical storage tanks have the problem of corrosion and perforation, and the requirements for both electrical conductivity and anti-corrosion are put forward for the electrostatic conductive coating. The effect puts doubts on the range of surface resistivity of conductive coatings, and it is believed that corrosion will still occur if the resistivity is low, and it will be revised in the relevant standards, from 10 5 ~10 9 Ω is modified to 10 8 ~10 11 Ω, while the surface resistivity of conductive coatings reported in many patents and literature is in the range of 10 5 ~10 9 Ω
