Wood-to-paper process
Deinking The process of removal of printing-ink from printed paper, in order to re-use the fibrous material of the paper. By removal of the printing-ink, the brightness of the new paper formed from recycled fibres is enhanced.
Paper coating The process of modifying the paper surface in order to obtain special properties - often to improve printability.
Paper making The process of making a paper-sheet from a suspension of cellulosic fibre materials, pigments and other chemical additives.
Pulping The process of liberating cellulosic fibres / fibrous materials from plant materials (most often wood) - by mechanical - and / or chemical means.
Recycling The process of re-use of the cellulosic fibres from old/ used paper and paper-board.
Product Types
Cleaners Additives to remove deposits from surfaces ("washing").
Co-binders Additives functioning together with the main binding system (often latices) to improve certain characteristics of the paper-surface.
Collectors Additives used to collect the released ink-particles at deinking - whereby an improved separation of ink and fibres for re-use takes place.
Defoamers Product used to control / suppress the formation of foam.
Deposit control The regime to reduce / prevent unwanted attachments to - / deposition on surfaces.
Insolublizers Additives reducing the water-solubility of certain additives used in paper-coating.
Lubricants Additives used to reduce friction and in paper-coating often to reduce formation of dust.
Chemical terms
Absorbency The degree of uptake of a material (or energy). Often related to uptake of water.
Adhesion The process of attachment of a material to a surface.
Anthraquinone Additive improving the cooking process of wood chips - enhancing the release of the cellulosic fibres.
Block polymers Polymers composed of various parts ("blocks").
Brown stock Released cellulosic fibres in the brown cooking liquor (stained by the released lignin materials) - i.e. the fibrous material in the pulping process before bleaching.
Calender A stack of rolls / cylinders used to increased surface-smoothness and / or gloss.
Carry over Unwanted transfer of material / components from one process to another.
Cobb value A value for measuring the degree of water uptake of paper.
Cooking additives Additives used in the chemical pulping process to aid the release of the cellulosic fibres from plant materials (wood).
Delignification The process of removing the lignin material from the cellulosic fibres.
Digester additives Additives used in the cooking of plant materials (under high temperature and pressure) - whereby one intends to liberate the cellulosic fibres.
Dispersion A suspension of solid particles in a fluid.
Dusting Formation of small "dust"-particles - which negatively influence the environment or a manufacturing process.
Effluent plant The plant for treatment of discharges before the water is let out to a recipient.
Enzymes Proteins starting or speeding up (catalyses) chemical reactions.
Fatty acids Long chained organic acids - derived from fat from plants, animals or fish.
Fatty alcohol dispersions A dispersion where an important part of the solid particles contain fatty alcohols, i.e. long chained, solid alcohols.
Hemicellulose Polymers of sugars, present in vegetable materials - more water-soluble than cellulosic fibres.
Hydrophobizing A process to reduce the wetting / uptake of water.
Incineration Burning at high temperature.
Organic components Chemical structures containing carbon as the most essential element.
Paraffinic types Straight chained materials containing carbon and hydrogen atoms.
Runnability How well a machine can run.
Silicone Water repellent material - based on a silicon-oxygene backbone in combination with organic carbon structures.
Softeners Additives that increase the softness of fibrous materials (paper or textiles).
Surfactants Chemical components which have the tendency to concentrate on inter-phases - f.ex. border-phases between water and air or water and some oily material. Surfactants have a water soluble part and a water insoluble part of the molecule (various types of "soaps").
Waxes Water insoluble, organic materials with a fatty character - solid at ambient temperatures.
Wetting Absorption and spreading of a liquid on a surface.
White fibre Bleached fibres.
