Study On Nanoparticles Modified Anticorrosive Coating For Power Transmission And Transformation Equipment

With the increasing expansion of power grid construction, the service life of powertransmission equipment and corrosion become prominent problem. Because of longrunning in the wild, power transmission and transformation equipment component arecorroded and damaged by all kinds of bad environment.The life of a power transmissionand transformation equipment are significantly shortened, and the safe operation isthreatened. Coating anticorrosive paint is used simply, performed excellently, repairedeasily, and applied widely, etc. What’s more, it can meet the demand of the complextypes of equipment, and can play a role of decoration and signature because of itsdiversified color. Due to the special work environment, power transmission andtransformation equipment put forward higher requirements to anticorrosion coating.Based on environmental factors and the sustainable development, anticorrosive coatingsare rapidly developing to the "green" and "high-performance"model. Corrosionprotection of power transmission and transformation equipment is very important toguarantee the safe operation of power system,so enough attention must be paid to thepower transmission and transformation equipment antisepsis problem.New type ofanti-corrosion coatings and the prevention and control technology with high quality, highefficiency, long life should be developed.This paper determined the preparation methods of new waterborne inorganiczinc-rich coatings by experiment, according to the power transmission andtransformation equipment anticorrosion requirements. Orthogonal experiment with theadhesion test and salt fog resistance test of coating are taken as its result indicators. Theoptimal formulation of new waterborne inorganic zinc-rich coatings are determined. Onthe basis of this, appropriate nano-materials Z, S, T are selected to modify waterborneinorganic zinc-rich coatings and orthogonal experimental test to determined optimalformulation.This paper test SEM and XRD characterization of laboratorycoating.Electrochemical impedance spectra test are designed to study the antisepticproperty.Analyzes technology and economy of laboratory waterborne inorganic zinc-richcoating and nano-Z modified water-borne inorganic zinc-rich coating with marketinorganic zinc-rich coating.The experimental results show that adhesion,salt fogresistance,paint film density of nano-Z modified water-borne inorganic zinc-richcoating’s anticorrosion performance are improved..The laboratory coating is superior tomarket inorganic zinc-rich coating technically and economically. And nano-Z modifiedwater-borne inorganic zinc-rich coating has more obvious advantages.
