Chemical method is mainly the application of paint stripper, and the method is widely used in aircraft maintenance process.The paint vehicle that aircraft skin paint (comprising priming paint and finish paint) is mainly made into by epoxy resin, polyurethane and acrylic materials.When carrying out depainting processing, paint stripper composition is penetrated into inside from coating surface, destroy coating resin molecule or intermolecular associative key, coating is expanded softening, the depainting component that is simultaneously penetrated into coating inside also can be destroyed the interaction of coating and base material, reaches the object that makes coating come off and then peel off from metal surface.In this process, unavoidably the aluminum alloy base material of aircraft main body itself is caused to corrosion.
Domestic main paint stripper product mostly contains the harmful components such as phenol, complex acid salt or carrene at present.Environment is had to negative effect, human body is also had to larger infringement.Paint stripper makes the enamelled coating swelling of substrate surface, after departing from, must just can make enamelled coating remove completely from substrate surface through high pressure water washing, so the sewage that contains a large amount of chemical compositions has caused secondary pollution to environment again with base material.
In addition, along with scientific and technological progress, and raising increasingly handling to aircraft, requirement on flexibility, the composite that quality is relatively light gets more and more and is adopted by aircraft industry.Chemical stripper can cause heavy corrosion to composite, so for take the aircraft components depainting that composite is matrix, chemical stripper is completely inapplicable.
For existing problem in above-mentioned prior art, the surperficial depainting process device of a kind of novel heating dust suction collocation of research and design Dry ice cleaning, is very necessary thereby overcome existing problem in prior art.
