摘要： A roll for use in the manufacture of paper and board, a press roll, in particular a center roll in a press, a backup roll for an extended-nip press roll, a hot press roll, or equivalent, which is in direct contact with a wet paper web, or a calender roll, a method for manufacturing the same and a coating composition therefor including an adhesion layer arranged on the frame part of the roll and a ceramic layer arranged on the adhesion layer. The ceramic layer has a thickness of from about 100 &mgr;m to about 2000 &mgr;m and includes from about 50% to about 95% by weight of Cr2O3 and from about 3% to about 50% by weight of TiO2, or from about 50% to about 80% by weight of Al2O3 and from about 20% to about 50% by weight of ZrO2, or exclusively Al2TiO5. The outer face of the ceramic layer is finished until the roughness Ra is from about 0.2 &mgr;m to about 2.0 &mgr;m and/or the porosity of the outer face of the roll is from about 1% to about 20%. In addition to or instead of TiO2, the ceramic layer may contain oxides of aluminum, silicon, zirconium, magnesium, manganese, tin, tungsten and mixtures thereof.

摘要： A press roll such as the center roll of a press or the back-up roll of an extended-nip press roll, used in a pulp, paper, board or finishing machine, has a coating with an intermediate sealed layer. The corrosion resistance and impermeability of the roll coating, particularly of such a coating that is made by thermal spraying, can be improved by way of sealing. The coating comprises a porous outermost surface layer made out of a ceramic or ceramic-metal material applied by thermal spraying and at least one sealed layer situated between the outermost surface layer and the roll mantle.

摘要： A press roll for a paper or board machine, a method for manufacturing a roll for a paper or board machine and a coating composition for a roll which enable the roll to endure difficult corrosion conditions. An adhesion/corrosion-protection layer having a thickness of from about 150 &mgr;m to about 300 &mgr;m is applied onto the frame part of the roll by a high-velocity flame spraying technique. The adhesion/corrosion-protection layer contains a nickel-chromium alloy. A tight-ceramic layer having a thickness from about 50 &mgr;m to about 150 &mgr;m is applied onto the adhesion/corrosion-protection layer by a high-velocity flame spraying technique and includes from about 50% to about 100% of Al2O3 and optionally includes up to about 50% of TiO2 and/or any amount of Al2TiO5. A porous ceramic layer is applied onto the tight ceramic layer. The tight-ceramic layer may include only Al2TiO5 instead of Al2O3, with or without TiO2.

摘要： A coated press or transfer belt and method for coating a press or transfer belt is disclosed, wherein a coating of one or more polymers and possible blend components and additives is formed on the surface of the belt. Coating is carried out by rotational molding, which is, as such known, onto the belt rotating on one or more rolls from at least two rapidly reacting liquid components. The set coating layer is then ground to an even thickness.

摘要： A roll for a pulp machine, paper machine, or paper finishing machine with a cylinder mantle of cast iron or steel, or any other equivalent metal, which bears the mechanical loads. On the roll mantle, fixed to the outer face of the mantle, there is a resilient polymer coating, and onto the polymer coating a coating is fixed which is by several orders thinner than the radial thickness of the polymer coating. This coating fixed onto the outer face of the polymer coating is a metal, ceramic, cermet or plastic coating.
