摘要： Methods of increasing formability of a palm sheath material, methods of producing a palm sheath-based product, and palm sheath foodware produced thereby. The formability of a palm sheath material is increased by treating the palm sheath material with a fluid substance that weakens bonds between cellulose fibers of the palm sheath material by partially eliminating lignin and hemicellulose of the palm sheath material. The treated palm sheath material can be used to form various products, such as foodware products by deforming the treated palm sheath material into a shape. Advantageously, the treated palm sheath material can typically be deformed by stretching or punching using dies to a height to diameter aspect ratio of greater than 0.2 and/or to a limit strain of the palm sheath material greater than 0.38.

摘要： The present invention provides a process for producing paper or board, comprising slushing a stock of dried fibres in a slushing system comprising a pulper, and/or feeding a stock of never-dried fibres in a fiber line of an integrated paper mill; deflaking and/or refining the stock in a deflaker and/or a refiner, optionally diluting the deflaked and/or refined stock, directing the deflaked and/or refined stock to a headbox, forming a web, and drying the web, wherein a polymeric paper making additive is added to one or more of the stocks of dried fibres and never-dried fibres before deflaking and/or refining of the stock. The present invention further provides paper and board with improved properties.

摘要： The invention relates to a method for controlling hydrophobic particles in aqueous environment in paper or board manufacture. The method comprises preparing an aqueous stock comprising natural fibrous material, feeding the stock to a wire section, where a fibrous web is formed by draining excess water through a wire, and adding a control chemical to aqueous environment at least in one dosage point between the preparation of the stock and the exit of the web from the wire section. The control chemical comprises performic acid, which is added to the aqueous stock, which has consistency of at least 3 weight-%.

摘要： Water-resistant, protein-based adhesive dispersion compositions and methods for preparing them are provided. The adhesive dispersions are prepared by copolymerizing a denatured vegetable protein, such as soy flour, that has been functionalized with methylol groups with one or more reactive comonomers, and preparing an acidic dispersion of the adhesive. The adhesive dispersions exhibit superior water resistance, and can be used to bond wood substrates, such as panels or laminate, or in the preparation of composite materials.
