Study on Influencing Factors of Corrosion Resistance of Hot Dip Galvanized Fingerprint Sheet

In this study a lot of production verification and test had been conducted to find the factors that influence the corrosion performance of fingerprint resistant sheet. It is found out that the corrosion resistant properties of hot dip galvanized fingerprint resistant mainly relates to drying temperature,film thickness,roughness,PC value and cure time.In the process of inspection and processing stamping and scratch exert effect on the corrosion resistant properties of the skin membrane.Based on the above observations,the corresponding relationship between the corrosion resistance and the drying temperature,film thickness,the roughness of the substrate and the PC value,cure time has been established,at the same time stamping and scratches during the inspection and processing has been avoided.All these measurement help to achieve the sheet meeting the technical requirements for the index of corrosion resistance,and guarantee the stability of hot dip galvanized fingerprint resistant corrosion performance.At present,the steel company is able to supply the hot dip galvanized fingerprint resistant sheet to Belgium and other European countries.
