    摘要： A method of producing a paper board comprising: a pulping step of disintegrating and beating fibers from a pulp raw material containing waste paper as a main raw material to obtain pulping process water; a stock preparation step of adding an additive containing a paper strength additive to the obtained pulping process water to obtain a prepared pulp raw material; and a paper-making step of making the obtained prepared pulp raw material into a paper board, wherein the paper board is produced by adding (a) an aqueous solution of hypochlorite and (b) an aqueous solution of water-soluble inorganic ammonium salt or ammonia water to the pulping process water to reduce the amount of the paper strength additive added in the stock preparation step.

    摘要： Methods to preserve starch present in pulp are provided and also methods to control calcium precipitation and/or scaling in digesters or BOD systems. The methods can be performed as part of a papermaking process. Process water containing pulp can be treated with a chloramine. Process water containing pulp with native starch can receive a double treatment with at least one biocide, such as chloramine, and at least one oxidant, such as sodium hypochlorite. The treatment can be performed in any suitable manner. The treatment can be performed at one or more stages or locations in a papermaking system. A target residual chloramine value or range can be achieved by the treatment. Packaging sheets/boards and other paper products manufactured using the methods provided exhibit superior strength and other desirable characteristics.
