20210292687 · 2021-09-23 ·

A roll of cleaning fabric is used for cleaning printing cylinders of a printing system. The cleaning fabric (13) is impregnated with a cleaning composition containing an organic solvent and a cellulose solubilizer. The roll may be wound around a core (14) and inserted in a removable sealing bag (15) configured to seal around the roll (12) of cleaning fabric (13) in order to prevent the cleaning composition from evaporating before use.

USE OF DI-IONIC COMPOUNDS AS CORROSION INHIBITORS IN A WATER SYSTEM

Disclosed herein are the methods of using di-cationic or di-anionic compounds, which are derived from primary amine through an aza-Michael addition with an activated olefin, in a corrosion control composition to mitigate corrosion of a surface in a water system. The disclosed methods or compositions are found to be more effective than those methods or compositions including commonly used single quaternary compounds for mitigating corrosion for a metal surface in water systems.
