摘要: Lignin amines are disclosed which are characterized by high nitrogen content and are water soluble at both alkaline and acidic pH values. The lignin amines have utility as flocculants, filtration aids, precipitants, scale inhibitors, asphalt emulsifiers, fluid loss additives, oil well cement additives, corrosion inhibitors, retention aids, cationic dispersants, and tall oil pitch emulsifiers.

摘要: Paper, board and cardboard are produced by draining a pulp slurry in the presence of high molecular weight, water-soluble polymers of N-vinylamides as drainage aids, retention agents and flocculants. These polymers are particularly effective in a pulp slurry which has a high content of interfering substances and other phenolic compounds.

摘要: The present invention concerns a process for producing a thermoformable porous web using a mixture of cellulosic fibers and one or more thermoplastic materials, particularly by foam forming said mixture into a composite foam, and applying the foam into one or more layers on a support to obtain a porous pre-form web. The thus produced porous composite web can be further processed by compression molding to give a rigid high-strength composite structure, which is suitable for use in producing, e.g. panels or plates, packages or hygiene products, insulators or filters, or printed intelligence, electronics or microcellulose products.
