Abstract: A process for the comminution, in particular defibrillation, and reaction of fibrous materials having a high dry solids content with the addition of a circulating medium, preferably a carrier gas and/or reaction agent, as well as optionally of chemicals. The invention is mainly characterized in that the circulating medium is recycled after leaving the comminuting device, by changing its temperature, and is then recycled to the comminuting device. Another embodiment of the invention is characterized in that the fibrous materials and liquid reaction agent are separated from the carrier gas and reaction agent vapors, which are then recycled back to comminuting device. A plant for carrying out this process is mainly characterized in that the comminuting device and route for recycling and treatment of the circulating medium form a closed system.

Abstract: A refining process for paper pulp in which colloidal silica sol is mixed with the paper pulp to be refined. The addition of the colloidal silica sol reduces the time necessary to refine the pulp to a predetermined freeness value compared to refining in the absence of the colloidal silica sol.

Abstract: High strength and high density wood fiberboard is formed by treating the wood fiber source material with a highly alkaline solution, such as sodium hydroxide solution, before interfelting the fibers into a loose mat. The wood source material may be treated after refining the material into fibers, but preferably, the wood source material is treated before fibrillation. Further, wood fiber source material may be partially neutralized before felting without substantial change in the resulting densities and strengths.
Abstract translation: 在将纤维粘合到松散垫中之前，通过用高碱性溶液如氢氧化钠溶液处理木纤维源材料来形成高强度和高密度木纤维板。 在将材料精炼成纤维之后，可以处理木材来源材料，但优选地，木材来源材料在原纤维化之前被处理。 此外，木纤维源材料可以在毡化之前被部分中和，而不会导致密度和强度的实质变化。

Abstract: The present invention provides a process for producing pulp which includes the step of adding alkaline salt of aluminate to pulp material to reduce energy consumption in the mechanical treatment of the pulp material, and alkaline salt of aluminate for use in such a process and pulp as produced by such a process. In preferred embodiments, the present invention provides such a process for producing pulp at a wet pulp material maximum pH of about 8.5, and a process that includes the step of adding at least one pound of alkaline salt of aluminate per dry ton of end product pulp, and a process where the mechanical treatment is a mechanical refining process, particulary mechanical treatments that are at least a part of treatments known generally as refiner mechanical pulping and thermo mechanical pulping, and alkaline salt of aluminate for use in such processes and pulp as produced by such processes.

Abstract: The continuous treatment of a cellulosic material in the form of chips to produce at least partial delignification of the material without true mechanical grinding is effected in apparatus comprising two parallel meshing screws which are rotated in the same direction in a sheath and have identical threads providing a plurality of zones of different pitch. The material is passed in succession through a first zone for feeding the material downstream, a first braking zone for causing a first compression of the material, a second zone for feeding the material downstream and in which the material is brought into contact with a reagent, e.g. steam or a chemical reagent, and a second braking zone for causing a second compression of the material. In each compression stage the material is subject to alternate increases and decreases in pressure, the first compression stage causing the expulsion of any water present in the material and the second compression stage causing the expulsion of any spent reagent and residual liquors in the material.
