摘要:
The invention relates to a method for treating a surface of a substrate, said method comprising applying a functional chemical onto the surface of the substrate for improving the adhesion of silicon to said substrate. The method further comprises applying said functional chemical in an amount of at least 5 mg/m2 onto the surface of the substrate by using a steam application beam to form a functional chemical layer on the substrate, which functional chemical comprises double bonds, silane hydride, or vinyl silane reactive groups, or oligomeric or polymeric hydrocarbon or polysiloxane compounds.

摘要:
The present invention relates to a release liner composition in which the adhesion of silicone has been improved between a silicone coating and a surface treating layer and so silicone rub-off prevented. The improvement of adhesion is based on a polymeric surface treating agent structure comprising a moiety or moieties that are compatible with a substrate and/or a coating on the surface of the substrate, and a moiety or moieties that are reactive or at least compatible with the silicone coating. The present invention also relates to a base material and a method of producing a base material, and a surface treating agent for a base material and a use of a surface treating agent.

The invention relates to a method and apparatus for removing water in paper-making, wherein paper is formed by feeding pulp to a wire section (2) through a headbox, a web is formed at the wire section, and the web is led from the wire section to a drying section (4) through a press section (3). According to the invention, dewatering the web is enhanced and moisture content of the paper is reduced by removing water from the web (5) the is being formed by at least one dewatering unit (8) comprising a belt circulating member (10) with a belt (11) and at least two rolls (12) over which the belt is arranged to pass.

The invention relates to a method and apparatus for removing water in paper-making, wherein paper is formed by feeding pulp to a wire section through a headbox, a web is formed at the wire section and the web is led from the wire section to a drying section through a press section. According to the invention, dewatering the web is enhanced and moisture content of the paper is reduced by removing water from the web that is being formed by at least one static shoe press unit, the static shoe press unit being selected from the following group:a) using at least one static shoe press unit in conjunction with the wire section; b) using at least one static shoe press unit between the wire section and the press section; c) using at least one static shoe press unit in conjunction with the press section; d) using at least one static shoe press unit between the press section and the drying section; e) using at least one static shoe press unit in conjunction with the drying section; and/or f) using at least one static shoe press unit in conjunction with calendering.
