摘要： A method of making a shaped cellulosic paper or paperboard, comprising the steps of:(a) diluting cellulosic fibers with water to form an aqueous suspension of less than 10 percent by weight cellulosic fibers;(b) agitating the aqueous suspension of cellulosic fibers until the fibers become separated from each other and swollen;(c) dewatering the aqueous suspension to at least 20 percent weight cellulosic fibers;(d) preparing a homogeneous, plastically formable material by adding to the suspension sufficient hydrocolloid to bind substantially all of the water in the material to prevent the water from bleeding out during subsequent shaping and to prevent the fibers from flocculating, and by kneading the material, said material containing water in the range of from about 50 to about 90 percent, fibers in the range of from about 8 to 49 percent, and hydrocolloid in the range of from about 1 to about 20 percent, by weight;(e) shaping the material by extrusion, injection molding, rolling, pressing or drawing, and(f) bonding the solids of the material by drying the shaped material.

摘要： A method of making a cellulosic paper or paperboard by agitating an aqueous suspension of cellulose fibers until they become separated from each other and swollen. A sufficient amount of hydrocolloid is added to bind the water in the suspension such that no water will bleed out during a subsequent shaping. The mixture is kneaded until a homogeneous, plastically deformable mixture is formed. The mixture contains about 50-90% water, fibers in excess of about 8% and hydrocolloid in excess of about 1% by weight. The mixture is shaped by extrusion, rolling, pressing or drawing.

摘要： The invention describes a method for dispersion of cellulose based fibers in water. The raw material, which particularly may be recycled paper, is first wetted with water. By a combination of addition of hydrocolloid which binds water, and strong kneading at high solid content, the mixture is transformed into a modulable paste. The high viscosity of the paste effectively conveys the shear forces of the kneading machine to make the fibers flexible and tear them apart. When the kneading is terminated, the hydrocolloid prevents the fibers from reassociation into fiber bundles.

摘要： A dispersion of cellulose based fibers in straw is produced by the aid of alkali and strong mechanical agitation. This solubilizes the pentosane in the straw, and turns the mixture into a high viscosity paste, so that the forces from the agitation tear the individual straws apart and disperses the fibers. In this way the fibers can be dispersed at solid content up to 85% compared to only 8% by traditional methods. The treatment results in a molding paste, which can be used directly for plastic forming of cellulose based fiber products after neutralizing.
