Preparation of Antisulphuric Paperboard and Its Aapplication in Packaging Industrial Silver Products

Abstract

An antisulphuric coating manufactured by U.S. michelman was coated on the case board to prepare antisulphuric packaging paperboard. The silver strip samples were wrapped in antisulphuric packaging paperboard under laboratory condition in a simulated extreme sulfur-containing atmosphere, then the corrosion status of silver strip samples were observed and the effect of antisulphuric packaging of the coated paperboard with different coating weight were tested and analysed. The results show that antisulphuric packaging paperboard with coating weigh 18-22g/m 2 applied to wrap industrial silver products, its comprehensive protective effect and physical properties are better, and it can avoid the economic loss caused by the corrosion of silver products due to exposure to the industrial atmosphere.
