  • Patent number: 10640923
    Abstract: The invention relates to a method for treating starch in pulp, paper and board making processes, in which processes recycled fibre material is used as raw material wherein the recycled fibre material is pulped in a pulper and obtaining a pulp flow comprising an aqueous phase and at least recycled fibres and starch dispersed in the aqueous phase. The method comprising the following steps: —adding amylase enzyme inhibitor and/or at least one biocide to pulp flow or to an aqueous process flow comprising starch for preventing starch degradation, and—adding an amphoteric polymer obtained by copolymerisation of (meth)acrylamide with cationic and anionic monomers to pulp flow or to an aqueous process flow comprising starch for binding starch to the fibres.

  • Patent number: 8734615
    Abstract: The invention relates to a method for impregnating and drying a continuous paper web (1) by means of a urea resin dissolved in water, and to a corresponding system. Such paper webs (1) are employed for example as furniture foil or floor laminate, wherein in the known art melamine resin is used exclusively for bonding to a substrate. This is relatively expensive. Therefore the object of the invention is to create a method in which the paper web (1) which is impregnated by means of urea resin can be bonded to the substrate with a high degree of operational reliability. Said object is achieved in that the temperature of the paper web (1) is determined separately in each of the drying zones (3.1, 3.2, 3.3, 3.4), that for each of the drying zones (3.1, 3.2, 3.3, 3.4) an amount and/or a temperature of the circulating air are regulated so that the maximum temperature of the paper web (1) is 99° C., and that exhaust air is extracted from a first one of the drying zones (3.1, 3.2, 3.3, 3.

  • Patent number: 8282778
    Abstract: The invention relates to a method for preventing or delaying bacterial sporulation in the broke system of a board or paper machine by lowering the content of transition metals in the broke to a level unfavorable for sporulation. Preferably bacterial cells present in the broke system of the board or paper machine are not substantially killed by the procedure used for lowering the content of the transition metals. The invention further relates to a method for producing packaging board or packaging paper having a low bacterial spore content.

  • Publication number: 20120193054
    Abstract: Methods and apparatuses for forming a nonwoven web are described herein. The apparatus includes a mixing partition defining one or more openings therein that permit fluid communication between two fluid flow streams, at least one of which includes a fiber. The apparatus also includes an enclosed region surrounding at least a portion of the mixing partition. The enclosed region is adapted to provide an applied pressure to a fluid flow stream to urge the stream through one or more of the openings in the mixing partition. The apparatus also includes a receiving region designed to receive at least a combined flow stream and form a nonwoven web by collecting fiber from the combined flow stream.
