Abstract: The present invention provides a method for forming a pattern on a synthetic wood board to form, on a surface of the synthetic wood board, a pattern such as wooden grain and the like which is close to natural wood, to enhance the reality of woody like appearance. The synthetic wood board is formed by mixing 35-80 wt % of thermoplastic resin material and 20-65 wt %. By a first grinding process, the synthetic wood board is formed at its entire surface of at least one side thereof with a large number of wound stripes in one direction. By a colorant coating process, a colorant is coated on the surface on which said wound stripes are formed, the colorant impregnates in wood meal on the surface to generate blur. And some colorant remain in recess portion of the wound stripes to form recess pigment layer.

Abstract: The thermoplastic resin waste containers are crushed into coarsely crushed pieces, an impact-grinding force and a centrifugal force are applied on the coarsely crushed pieces so that oily foreign objects be separated; i.e., the oily foreign objects are separated by the impact force and the grinding force. The difference in the centrifugal force separates the resin from the foreign object, the centrifugal force on the resin pieces being controlled by the impact-grinding force, while the centrifugal force on the oily foreign object is free from it. In the course of this process, the crushed pieces to be treated are formed into granules by the impact-grinding force, and the granulated granules are reused as a resin material. Foreign objects other than oils can be separated and removed more easily than oils.

Abstract: A method and apparatus for individually collecting layers from a laminated film containing many layers made of different materials by peeling or separating the layers one from the other. The laminated film having a plurality of layers made of different materials is shredded into a plurality of fragments to be processed; and the fragments to be processed are peeled or separated according to the type of layer by applying an impact frictional striking force to each of the fragments to be processed. Subsequently, the peeled or separated layers obtained in the peeling and separating step are subjected to a wind force classifying step. The collected layers in the mixed state are separated from one another, and they are individually collected.

Abstract: Provided are a reprocessed resin which decreases volume of a thermoset resin foamed material recovered from waste of various resin products and moldably form said thermoset resin foamed material into various molded articles to thereby effectively recover and reprocess the thermoset resin foamed material, a reprocessing method therefor and a method for molding a molded article formed of said reprocessed resin. A pulverized resin to be processed formed of a thermoset resin foamed material along with a thermoplastic resin molding material are applied with a stirring impact force to produce shearing heat generation based on the stirring impact force and are gelled and blended by the shearing heat generation. In this process, the thermoplastic resin molding material is adhered so as to cover the whole surface of the individual pulverized resin to be processed and cooled and granulated to have 15 mm or less of particle diameter to thereby decrease volume by 0.

Abstract: The present invention is intended to, from thermoplastic molded resin articles composed by a variety of laminating thermoplastic resin materials, separate, classify, select and recover the thermoplastic resin materials with classification in terms of type for reusing these materials.

Abstract: A resin material is recovered for recycling from industrial waste of plastic film, unlike conventional methods, without requiring washing and drying the steps for removing foreign objects adhering thereto such as agricultural chemicals. A method for recovering a resin material from industrial waste film according to the invention comprises the steps of crushing waste film into crushed small pieces to be treated, applying a scraping impact force to the crushed small pieces to remove any adherent foreign objects and separate them from each other. Then, the separated crushed small pieces are size-regulated and for regeneration.

Abstract: A synthetic wood meal in which a thermoplastic resin material of 25 to 80 wt % is mixed with a cellulose crushed material of 20 to 75 wt % that lies in the moisture content of within 15 wt % and the mean particle diameter of 20 mesh or less, the mixed material is kneaded so as to be set to gel, and the kneaded material is cooled and pulverized and regulated to a size that lies in a particle diameter of 10 mm or less. Then, the synthetic wood meal as the cellulose crushed material is mixed in at the rate of 20 to 75 wt % to the resin material, the mixed material is kneaded by heating and squeezed by a screw or screws of an extruding die 78 in an extruder.
