IPC: A47B77/00
Filed: 1998-09-08
Abstract: PROBLEM TO BE SOLVED: To improve the adhesiveness of a waterproof seal and an adhesive by applying a discharge process as a pretreatment when a fluorine paint coating or a fluororesin film laminate is used on the surface. SOLUTION: A sink cabinet 2 is fitted to an interior wall face 1 via a waterproof seal 3 in a kitchen, and a shelf 4 is fitted via an adhesive 5. When a fluorine paint is coated or a fluororesin film is laminated on the surface to make stains to be hardly stuck and easily removed, the adhesiveness is inferior, thus a discharge process is applied as a pretreatment to reform an execution face. As the discharge process, a corona discharge is generated between electrodes to expose the execution face to the discharge space, or an arc discharge is generated between electrodes and sprayed to the execution face by the gas flow such as air. The nonadhesive execution face is reformed, and the watertightness and airtightness of the waterproof seal 3 and the adhesive 5 can be improved.
