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.

The paper itself is formed from a particular paper pulp composition which contains fatty acids and/or fatty acid salts and an aluminum salt, as well as, if necessary, alkylketenedimer. Such paper pulp concentration contains, furthermore, anionic and cationic polyacrylamides in the ratio of 40:60 to 60:40, as well as an epoxidized fatty acid amide. The acrylic acid content of the anionic polyacrylamide amounts to between about 5% and 20%.

摘要： The present invention relates to certain compositions and processes useful for inhibiting the growth of microorganisms in water and, in particular, water used for industrial purposes; for example, in the manufacture of paper, in cooling water systems, in effluent water treatment, and in secondary recovery petroleum operations. The novel processes and compositions of the present invention are processes or mixtures which show unexpected synergistic activity against microorganisms, including bacteria, sulfate-reducing bacteria, fungi, and algae, which produce slime in aqueous systems where such slime is objectionable from either an operational or aesthetic point of view. Specifically, the invention is directed to the use of compositions comprising 2-(thiocyanomethylthio)benzothiazole and 2,2-dibromo-3-nitrilopropionamide.
