Thermosetting paint film is removed by adding plastic resin coated with thermosetting paint film into a mixed solution of an alcoholic solvent and alkali and heating this mixed solution while stirring. Isopropyl alcohol, phenoxy alcohol and alkali are added in a reactor and heated to a temperature of 50-70° C. while stirring. Plastic resin coated with thermosetting paint film is added and a reaction is performed while maintaining the temperature. The isopropyl alcohol and phenoxy alcohol are added in a mixed ratio of 70-90:30-10.
摘要:
An apparatus continuously treats the surface of waste rubber powder by means of microwave thereby making it possible to treat the surface of waste rubber powder continuously and more efficiently. As a result, recycled rubber material has superior surface roughness and processability and the physical or chemical properties of the rubber articles are improved.

摘要:
A heated high pressure air and/or a high pressure water are spouted through nozzles. Therefore, the coated layer is removed without crushing the bumper unlike in the conventional method, and therefore, a plurality of process steps can be skipped. Thus the bulk of the apparatus can be reduced, the operating cost can be lowered, and the environment can be protected. The method for removing a coated layer includes the step of installing a bumper to be subjected to a removal of the coated layer. Then the coated layer is removed from the bumper by spouting water and/or a pre-heated air to the bumper. Then the bumper is carried to a predetermined psition after removing the coated layer, and then the bumper is detached. The apparatus includes an installing/detaching means for installing/detaching the bumper to be subjected to a removal of the coated layer. A spouting device spouts a compressed air to the bumper thus installed to remove the coated layer from the bumper, and an air supplying means and a water supplying means respectively supply air and water to the spouting device. Then a carrying means carries the bumper to a predetermined position after the removal of the coated layer.
