20120080157 | DEGRADING AGENT COMPOSITIONS FOR TEMPORARY WET STRENGTH SYSTEMS IN TISSUE PRODUCTS - 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. | 04-05-2012 |
20120103543 | DEINKING PROCESS - 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. | 05-03-2012 |
