热镀锌耐指纹板抗腐蚀性能影响因素研究

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

通过大量的生产验证和试验来寻找耐指纹板抗腐蚀性能的影响因素。结果表明,热镀锌耐指纹板的抗腐蚀性能主要与烘干温度、膜厚、粗糙度和PC值、固化时间有关,在检验和加工过程中的冲压和划伤对皮膜的抗腐蚀性能也存在影响;建立了烘干温度、膜厚、基材的粗糙度和PC值、固化时间与耐蚀性的对应关系,规避了检验和加工过程中可能造成的冲压和划伤,使耐腐蚀性指标满足技术要求,保证热镀锌耐指纹抗腐蚀性能的稳定性。目前山东日照公司已具备稳定批量供货能力,出口比利时等欧洲国家。

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.
