ANTI-STAINING AGENT FOR PAPER MACHINE, AND METHOD FOR PREVENTING STAINS USING THE SAME

摘要

A method for preventing contamination of a paper machine is provided which comprises feeding a paper machine contamination agent comprising a modified silicone oil in which only a sidechain is substituted with an amino -or an epoxy-containing organic functional group directly and continuously to surfaces of the paper machine, followed by contacting an area of the paper machine with a wet paper web. Preferably, the paper machine contamination agent is applied to dryer rolls, canvas rolls, press rolls or a canvas of the paper machine.
