摘要： A method for removing wax from a pulp furnish is disclosed. The method is effective for removing wax from a pulp furnish containing waxed old corrugated containers (OCC). In the method, the pulp furnish containing waxed OCC is treated with an agglomeration chemical which separates wax from the fibers and agglomerates the wax for removal by screening. In a preferred embodiment, the pulp furnish is treated with a caustic material to enhance wax removal.

摘要： A method of treating wood-fiber pump, particularly wood-fiber pulp that contains recycled paper, comprises delivering the pulp to and advancing the pulp in a heating zone while delivering steam to the heating zone. The pulp is finely-divided in a disperser and the finely-divided pulp delivered to a screw press without separate departure of steam, so as to compact the pulp in the end of the screw press and therewith form a plug seal. At the same time, one or more bleaching chemicals is or are supplied during one or more treatment stages, and the temperature of the pulp is regulated to obtain an optimal bleaching process or optimal bleaching processes. The temperature of the pulp can be raised or lowered by supplying steam or water thereto respectively. The invention also relates to a plant for carrying out the method.

摘要： A method of treating solid containing material derived from effluent or sludge from a plant for de-inking paper, the material containing calcium in the form of one or more insoluble calcium compounds, the method including the steps of treating the material with an acid to cause dissolution of the calcium thereby forming a calcium ion-containing solution in which insoluble solids are suspended, separating the solution from the insoluble solids and incinerating the separated solids. The solution containing calcium ions may be treated by adding one or more reagents to form a calcium compound precipitate, eg calcium carbonate. The particulate solids produced following the incineration step and following the precipitate formation may be employed as pigments or fillers in paper making or paper coating.

摘要： A method of making sanitary paper products from recycled newspapers. The method includes the steps of: (a) pulping newspapers in water with agitation to produce a pulp slurry, the pulp from the newspapers having an average fines content of greater than about 40% and a Canadian Standard Freeness of less than about 250; (b) washing the pulp, whereby the fines content is reduced to less than about 35% and the Canadian Standard Freeness is increased to more than about 300; (c) introducing the treated pulp at a papermaking consistency into the headbox of a paper making machine; (d) adding from about 0.01% to about 1.5% of a surfactant system to the treated pulp; and (e) utilizing the treated pulp in a paper making process to produce sanitary paper products.

摘要： Raw materials useable in the manufacture of paper, cardboard and carton are recovered from waste sludge. After precipitation of the coarse particles, the sludge is centrifuged to remove black particles and then divided by fractional screening into its fiber, filler, pigment and agglomerate components. The agglomerate component is shear-treated and again fractionated, while the fibers, fillers and pigments, following further treatment if necessary, are fed to their points of reuse.

摘要： Recycled paper pulp having at least two different types of paper which consume widely different amounts of bleaching chemical, or mixed hardwood and soft-wood pulps, are treated in a manner that enhances distribution and redistribution of bleaching chemical to enhance uniformity of the bleaching treatment. The pulp is intensely mixed to provide a homogenous mixture of fibrous material and bleaching chemical, and then is continuously or intermittently subjected to mechanical action (such as in low intensity mixers, or by agitating pulp in a retention tank) of sufficient intensity and duration so as to enhance distribution and redistribution of a bleaching chemical. Also, recycled pulp will have cleanliness which varies significantly over time, and this is accommodated by sensing at least one of the brightness, color, or lignin content (e.g. all three) of the pulp prior to treatment in a first bleaching stage, controlling the quantity of first bleaching chemical added to the first stage in response to at least one of the brightness, color, or lignin content sensing to achieve a target brightness increase for the first stage, and then repeating the sensing and quantity control steps for a second and subsequent stages. Alternatively all sensing can be done initially. Within a stage, a valve may be controlled to subject the pulp to a second treatment in that stage, or to pass it out of the stage to the next stage, depending upon cleanliness.

摘要： A process for producing cellulose pulp and a filtrate of cellulose pulp that functions as a preservative for digestible food products that are intended for human and animal consumption. In the emulsification process wax paper, water, preservative potassium sorbate and the surfactant hydroxylated lecithin are heated and blended. The cellulose pulp is filtered through a filter having openings of about 2 micrometers. The cellulose pulp acts as a preservative when used with food products such as dietary fiber, a caking agent used in the dairy industry to prevent caking and clumping of graded cheese, dry seasoning and spiced soups. The cellulose pulp can also be used to improves the flowability of products which enhances their performance in packaging. The filtrate can be used as a water base for food products and acts to preserve the food product. Also fresh fruits and vegetables can be washed with the filtrate which increases the time that they can be stored without refrigeration.
