METHOD OF PREVENTING POLLUTION FOR DRY ROLLER USED IN PAPERMACHINE

摘要

The present invention relates to a method of preventing the contamination of a dry roller used in a paper machine which comprises the following steps: taping a fluorine resin tape (10) on a paper machine dry roller multiple times; wrapping a fluorine resin film (2) in which two fluorine resin layers (21, 22) formed of two different kinds of fluorine resins with different melting points are laminated on a joint (X) of the taped fluorine resin tape (10); then compressing the fluorine resin film with heat. The present invention enables users to readily and conveniently repair and manage the dry roller for the paper machine in the field, simplifies a facility by removing the necessity of having a separate spraying device for a surface formation agent to prevent contamination, and effectively improves releasing properties and contamination preventing properties of the dry roller.
