Provided is a paper machine contamination preventive agent that has high fixability to rolls and the like of a paper machine, that positively finds a silicone oil capable of imparting releaseability and water-repellent properties to the rolls or the like immediately upon being supplied to the rolls or the like, and that uses the silicone oil as a main component. Further provided is a paper machine contamination preventive agent using a silicone oil that permits transfer of less foreign matters from a wet paper web than that in a case where a contamination preventive agent containing a dimethylpolysiloxane base oil is a main component. The paper machine contamination preventive agent is fed to a paper machine and has a sidechain-type modified silicone oil or a sidechain both-termini modification silicone oil as a main component.

Anti-staining agent for paper machine, and method for preventing stains using the same

The invention provides a method of preventing contamination of a canvas of a paper machine, whereby antifouling effect on the canvas can always be maintained and precise drying efficiency is ensured. With the method of preventing contamination of the canvas for pressing a paper strip against the surface of drum-dryers used for drying the paper strip in a paper machine, a predetermined amount of a surface treatment agent P is continuously supplied to the surface of the canvases CC, facing the paper strip, in a stage of operation prior to the paper strip being pressed into contact with the canvases CCas well as the drum-dryers Cwhile the paper strip is being fed by operation of the paper machine.

Pollution prevention method for canvas used in paper machine

The invention provides a method of preventing contamination of a dryer of a paper machine so that predetermined effects of contamination prevention over the long term can always be ensured while maintaining satisfactory drying efficiency. With the method of preventing contamination of the surface of the drum dryer used in a paper machine, a predetermined amount of a surface treatment agent P is continuously supplied to the surface of the drum dryer Cin rotation, facing a paper strip W, while the paper strip is being fed by the paper machine in operation.

Pollution control method for cylindrical dryer used in paper machine

The invention provides a method of preventing contamination of a dryer of a paper machine so that a predetermined anti-fouling effect can always be ensured over a long term while maintaining satisfactory drying efficiency. With the method of preventing contamination of the surface of a drum dryer used in a paper machine, according to the invention, a predetermined amount of a surface forming agent P is continuously supplied to the surface of the drum dryer Din rotation, facing a paper strip W, while the paper strip W is being fed by the paper machine in operation.

Pollution prevention method for cylindrical dryer used in paper machine

An object of the present invention is to provide a method of preventing the over-adhesion of paper onto the surface of a press roll for a long time and preventing both wear and contamination in a paper machine. To do so, there is adopted a method of, in a press roll in a state in which paper is being supplied by driving a paper machine, preventing the over-adhesion of the paper onto a surface of the press roll, wherein wax whose melting point is lower than the surface temperature of the press roll is continuously supplied to a direct surface of the rotating press roll by the amount of 0.01 to 10 mg/m , that is a calculation on the basis of passing paper.
