Embodiment Construction

[0020] Specific embodiments of the present invention will be described in detail below in conjunction with technical solutions and accompanying drawings.

[0021] The advancing direction of the port of the paint stripping system of the present invention is shown by the arrow. In the accompanying drawings, the point light source adopts a xenon pulse lamp 7, and uses the reflector 5 to reflect the light emitted by the light source, and then irradiates the surface of the paint stripping object through the irradiation port, and the light energy is instantly converted into heat energy, so that the surface paint layer 3 is softened . The xenon pulse lamp tube 7 is covered with a pure water circulation cooling tube 6 to cool the lamp tube.

[0022] While the laser pulse xenon lamp is irradiating the surface of the object to be depainted, the dry ice blasting device uses the low-temperature dry ice particles in the high-speed airflow to depaint the area at -78°C. The dry ice particl...

Abstract

The invention relates to heating dust suction and dry ice cleaning surface depainting treatment equipment and a method, which belong to the technical field of surface treatment and are suitable for being used for removing paint films prepared from epoxy resin, polyurethane and acrylic resin materials, in particular to the depainting of metal paint films and composite materials on the surfaces of aircrafts, ships and armored vehicles. The equipment comprises a pulse dot light source heating device, a dry ice spraying device and a dust suction device, and when the equipment is used, a pulse dot light source carries out regional irradiation on the surface of an object to be depainted. Simultaneously, the irradiation region is depainted and cooled through low-temperature dry ice in high-speed air flows by the dry ice spraying device, and peeled paint fragments are directly recovered by the dust suction device without leaving residues in sites. The pulse dot light source heating device, the dry ice spraying device and the dust suction device are combined for depainting. Compared with the traditional physical depainting method, the method has the advantages that the cost is reduced, simultaneously, the efficiency is higher, in addition, no damage is caused on substrates, the environment is not polluted, and secondary contaminants are not generated.

Description

technical field [0001] The invention belongs to the technical field of surface treatment, and relates to a surface paint removal treatment equipment and method using heating and dust collection devices combined with dry ice cleaning, especially suitable for removing paint films made of epoxy resin, polyurethane and acrylic resin materials, especially It is used for the stripping of composite materials and metal coatings on the surface of aircraft, ships and armored vehicles. Background technique [0002] Paint can protect and decorate the substrate, but the paint film is often damaged during use, and it will gradually age during use. In addition to other reasons, the article needs to be repaired and renewed. The old paint film is mainly composed of film formers, pigments, fillers and appropriate additives. When painting or repairing mobile equipment such as aircraft, ships and armored vehicles, due to the gradual aging of the outer skin after a period of time, it is necessa...
