Quantified by the above-mentioned screw and mixing is generated, for example, a Maddock type, a dullage type or a barrier type. Equipped with a well-known screw of mixing pin type, and in a desired pellet form after mixing and extruding, for example, 2 to 5
It is molded into a desired shape such as a cylinder or prism with a size of about m / m. Further, in selecting the mixing screw, it is considered that the pellet-like material 3 having the dispersibility equivalent to that of the finely pulverized material (1 mmφ or less) is obtained. In the case of a biaxial type, a type in which an inorganic material is filled in and kneaded with a resin is usually used, and a screw configuration that can ensure sufficient dispersibility is used.

なり大変有用である。EFFECTS OF THE INVENTION The present invention provides a method for treating a PVC wallpaper, which is obtained by coarsely crushing the PVC wallpaper into a desired size through a screw having a high kneading performance, and then molding the PVC wallpaper into pellets. The pelletized product can be used for wallpaper or other uses other than wallpaper, for example, PVC decorative sheet, leather, etc., by mixing again in a desired amount in a PVC compound and dispersing. Therefore, even if a defective product that cannot be put out as a product is manufactured in the manufacturing process of PVC wallpaper, it can be reused for manufacturing a desired product without discarding it as in the past, and thus waste of resin is eliminated. Not only effective cost reduction, but also resource recycling is very useful.

る。Further, for example, since finely pulverized ones are bulky (apparent specific gravity: 0.2), only 7 to 8 kg can be put in a 25 kg bag, and the fare is expensive. Also, it is necessary to put 6 to 7 bags, and there is a risk that it will hinder the work, etc. Also, finely pulverized products are not hygienic because the powder flies around and stains the surroundings, and it is difficult to bag and it is easy to bridge. Although there is a fear, in the treatment method of the present invention, as described above, after the coarse pulverization, the fine pulverization is not carried out and the pellet is extruded into a pellet form, which is very suitable for reuse.
