  • Patent number: 10697116
    Abstract: In a method for producing nanofibrillar cellulose, cellulose based fibre material, in which internal bonds in cellulose fibres have been weakened by preliminary modification of cellulose, is subjected to disintegration treatment in form of pulp comprising fibres and liquid. The fibre material is supplied at a consistency higher than 10 wt-%, preferably at least 15 wt-%, to a disintegration treatment where fibrils are detached from the fibre material by joint effect of repeated impacts to the fibre material by fast moving successive elements and the weakened internal bonds of the cellulose fibres. The nanofibrillar cellulose is withdrawn from the disintegration treatment at dry matter which is equal or higher than the consistency of the fibre material. In the disintegration treatment, the fibre material is supplied through several counter-rotating rotors (R1, R2, R3 . . .

  • Publication number: 20140284407
    Abstract: In a method for producing nanofibril cellulose, cellulose based fibre material, in which internal bonds in the cellulose fibre have been weakened by chemical modification, are supplied, for separating fibrils, through several counter-rotating rotors outwards in the radial direction with respect to the rotation axis of the rotors in such a way that the material is repeatedly subjected to shearing and impacting forces by the effect of the blades of the different counter-rotating rotors, whereby it is simultaneously fibrillated.

  • Patent number: 8841374
    Abstract: A method for manufacturing an aqueous suspension of calcium carbonate by grinding in an aqueous medium in the presence of an acrylic grinding aid agent and of an alkali carbonate salt. These salts enable the quantity of grinding aid agent used to be reduced, for an equivalent level of performance in terms of rheology and granulometry of the suspensions. The method includes a first step of manufacture of the alkali carbonate salt within the aqueous solution of acrylic polymer itself, through the addition of alkali hydroxide and bubbling of carbon dioxide.

  • Patent number: 8833681
    Abstract: The current invention is directed to a method and apparatus for defibrillating cellulose fibers achieved through single or multiple passes of raw or pre-processed cellulose fiber slurry with a preferred solid material consistency range of 35% to 55% through twin-screw fiber processing machines. During this processing operation fiber slurries are optionally further enhanced with additional fiber and mineral additives to optimize performance of the material for specific end purposes. The hyper defibrillated fiber slurry produced can be defined as one reaching a Schopper-Riegler (SR) level between 75 SR and 85 SR and/or producing a pressed, dried board with a density of preferably at least 850 kg/m3.

  • Patent number: 8820666
    Abstract: A method for processing a supply of post consumer scrap linear low density or low density polyethylene film into near-virgin quality blown film product. The method includes tearing the supply of film in a shredder, wherein the surface area of the film is exposed, including delaminating the film. The torn supply of film is washed in a water bath including a surfactant. The film is agitated in the bath containing the surfactant wherein contaminants on the film are removed from the film. The washed film is ground into smaller pieces and additional washing of the ground film in a rotating friction washer occurs wherein additional contaminants are removed from the film. The ground film is then dried and compacted without addition of water into granulated objects of near-virgin quality blown film product.
