Failure Analysis of the Coating of Certain Containers
An on-site inspection was conducted on the coating failure of certain containers.The adhesion test of the coating was conducted on site.The chemical structure of the coating,the type of coating film-forming substances,the element content of the coating,the water-soluble ions in the coating,and the pH value of the coating were analyzed in the laboratory.The mechanism and reasons for the coating failure were discussed.The results show that the container may be corroded by hydrofluoric acid.The hydrofluoric acid penetrates and destroys the coating structure,causing the blistering,cracking and shedding of the container coating.
