    摘要： A dry strength additive composition generally includes an anionic and/or amphoteric polyacrylamide having a molecular weight of less than 1,000,000 Daltons, wherein the amphoteric polyacrylamide has a net negative charge; a cationic and/or amphoteric starch; and a cationic non-starch polymer having a charge density greater than 1 milliequivalent per gram (meq/g) at a pH of 3. The components defining the composition can be added to a pulp suspension sequentially or as a pre-blended mixture.

    摘要： A degrading agent composition for use in manufacturing a tissue product generally includes a degrading agent, a degradation inhibiting carrier, and a non-ionic surfactant. The non-ionic surfactant stabilizes the viscosity of the composition as a function of time. The degrading agent composition can be used in combination with a temporary wet strength agent to produce a tissue product exhibiting high initial wet tensile strength and desirable decay properties. Processes for forming the tissue product and pumpable fluids containing the degrading agent composition are also disclosed.

    摘要： The present invention provides a process for deinking printed waste paper comprising the steps of: a) converting the printed waste paper to an aqueous pulp slurry in a pulper, where ink is detached from paper pulp; b) subjecting the pulp slurry to flotation in order to remove hydrophobic contaminants including ink from the pulp slurry, said flotation being carried out in the presence of a deinking chemical additive comprising modified silica obtained by treating hydrophilic silica particles with a hydrophobic organic liquid or modified metal silicate obtained by treating hydrophilic metal silicate particles with a hydrophobic organic liquid or a mixture of such modified silica and modified metal silicate. The present invention increases the yield of the flotation step without affecting the brightness of the flotation accept.
