Composition， its use and method for removing and preventing wet strength resins from contaminating papermaking equipment

Compositions and methods for cleaning wet strength resin contamination from papermaking equipment and/or for preventing wet strength resins from contaminating papermaking equipment using the compositions are disclosed. The compositions comprise an aqueous solution of a weak organic acid; a surfactant， preferably a nonionic surfactant， a divalent metal ion containing catalyst and optionally a glycol ether containing solvent.

本发明公开了可用于从造纸设备上清除湿强树脂(wet strength resin)污染物，以及借助该组合物防止湿强树脂污染造纸设备的组合物与方法。该组合物包含弱有机酸的水溶液、表面活性剂(surfactant，优选非离子表面活性剂(nonionic surfactant))、含二价金属离子(divalent metal ion)的催化剂，以及可选的含二醇醚(glycol ether)类溶剂。
