Urea resin (urea-formaldehyde resin), phenol resin, unsaturated polyester, acryl, guanamine, epoxy or polyurethane, etc. can be used alone, or several kinds of thermosetting resins having different hardness, specific gravity and viscosity can be mixed. These materials are non-polluting even when used, have high electrical insulation resistance for the purpose of expanding the range of use, are resistant to alkalis and acids, have relatively high heat resistance, and have a risk of burning (flammable Non-toxic, non-flammable, toxic (styrene, ester, etc.)
Furthermore, it is selected from the viewpoint of a viscous material which is relatively hard to be powdery. Preferably, a resin plate-like molded product obtained by mixing a melamine resin or a phenol resin with a urea resin is crushed, or a melamine resin, a urea resin, and a phenol resin are each roughly crushed and mixed, and then crushed to form an irregular shape. A polyhedral delicate material is preferably used.

The particle size, hardness, and density of the crushed pieces of the thermosetting resin molded product used in the present invention are selected from the above ranges according to the type and thickness of the object (coating film) to be peeled. If a material outside the above range is used, abrasion marks may remain on the object to be peeled. Generally, a soft object uses a fine mesh having a low hardness and a hard object uses a coarse mesh having a high hardness. Also, as a binder,
Vinyl acetate, vinyl copolymer, chloroprene rubber,
Known adhesives such as a nitrile rubber type and a styrene butadiene rubber type can be used, and an epoxy type binder is particularly preferably used.

According to the adhered matter removing roller 10 of the first embodiment, since the material of the rotating roller is a soft resin or rubber having a porous structure, or a sponge-like material having a three-dimensional net-like structure, for example, when used, In FIG. 5A, FIG.
