| This invention concerns a process for producing fiber-reinforced materials using physical methods which is characterized by an extraordinary increase in the intermolecular hydrogen-bonding by means of a corresponding, physical enlargement of the specific fiber surface and a refinement of the fiber structure suited for contact formation, wetting, and felting. This is done by continuous grinding of the cellulose fibers or other fibers and plants containing cellulose in a refiner or other suitable fiber crushing or defibering equipment. Subsequently, after optional preliminary drying, the aqueous microfiber pulp is molded and dried. The primary material hardens by itself through drying and concomitant shrinkage, without addition of bonding or filler materials and without use of any external pressure, to a specific gravity of 1.5. | ||||||

| 104 | METHOD FOR ADJUSTING THE FIBROUS PROPERTIES OF PULP | EP03712162.1 | 2003-03-21 | EP1488037A1 | 2004-12-22 | RANUA, Jukka; LILLEBERG, Risto |
| The invention relates to a method for adjusting the fibrous properties of chemical pulp, mechanical pulp or chemi-mechanical pulp, for adjusting the smoothness of the properties and for decreasing any variation in quality. According to the method, in the manufacture of pulp, a wood material is used, which is selected according to the number of the tree’s annual rings. The wood material is classified according to the number of annual rings into categories that represent a certain fibre dimension property, such as the fibre length or the fibre coarseness. The wood material is classified by log or group of logs at any stage in connection with the felling of the wood or in the plant or at some stage of the chain between the stub and pulping and grinding or a refiner. | ||||||

| A cellulose mixture including a protein based adhesive binder and colorant. The mixture can be compression molded or extruded and upon curing in the presence of microwave or radio frequency energy or in a thermally controlled appliance, produces board or shape formed stock. The produced stock exhibits colorations and a grain pattern comparable to natural stone. Unlike stone, the material exhibits a light weight, low density, structural rigidity and ready machinability. A preferred method includes admixing separate, colorized batches of feedstock, each feedstock includes shredded waste newsprint, soybean flour, water and a colorant; reducing the moisture content of each feedstock or a proportioned admixture of several feedstocks, such as by air drying or compressing or performing the admixture in the presence of heat; compacting the admixture to final shape; and curing the shaped material. Final forming and finishing apparatus complete the process. | ||||||

| 120 | Arundo donax pulp, paper products and particle board | US11392862 | 2006-03-28 | US20070056702A1 | 2007-03-15 | Ernett Altheimer |
| Composite panels and pulp, and paper products of the pulp, are produced from Arundo donax. In the fabrication of the composite panels, Arundo donax is comminuted to a suitable size, combined with a binder, and consolidated into panels that meet standards for construction and/or furniture grade panels. The Arundo donax particulates may be combined with wood particulates to produce a mixed furnish that can be used in the preparation of composite panels. Comminuted Arundo donax is treated, in conventional pulping processes, to produce a high tensile strength pulp that can be used in the production of paper. The pulp has a lighter color than wood pulp, and thereby uses less bleaching chemicals to achieve a desired whiteness. The pulp can be combined with wood pulp to produce a variety of products. | ||||||
