探讨无溶剂复合镀铝结构白色变灰的问题

Discuss The Problem Of White Becomes Gray In Solvent-Free Composite Aluminum Coating Structure

胶水粘度越高,对油墨白度的影响也越小,反之粘度越低则对白色油墨变灰影响越大。本文认为复合镀铝膜的胶水往高粘度和高流平方向发展会更适合。

The higher the viscosity of the glue,the smaller the influence on the whiteness of the ink,On the contrary,the greater the impact on the graying of the white ink,This paper believes that the glue of the composite aluminum coating film will be more suitable for the development of high viscosity and high leveling.
