Preface
Refer aviation, we what can think of for a short while is feeling of science and technology. Right, the plane is an accurate and complex machine —— from giant wing, powerful engine, to sophisticated aviation electron equipment and mechanical system, every component is made through strict design and accurate craft.
However, the besmear outfit of the plane also is a knowledge actually. Regard the “ dress of the plane as ” , besmear outfit can publicize experience of flight of user of company culture, promotion not only, was to assume more show for the plane outline, anti-icing, prevent ultraviolet ray of rain, anti-fouling, anticorrosion, adiabatic, keep out to wait for safe safeguard to weigh duty. The body of doorsill of science and technology of plane coating its are durable sex, protection, energy-saving now decrease heavy, fight the ultraviolet ray and radiation protection, side such as environmental protection standard. We often say coating of ability in swimming is an environment friendly model a kind of coating, so what application case does coating of ability in swimming have in aviation domain?
Case
The application of paint of ability in swimming in aviation domain
The coating of ability in swimming of green environmental protection also got wide attention in aviation domain. If the adornment coating inside plane engine room chooses coating of ability in swimming commonly, the modified polyurethane system of the acrylic acid of ability in swimming that our country has independent intellectual property is applied in the coating system of the cabin inside the plane, be able to bear or endure water, flame retardant, oil resistant, be able to bear or endure corrupt the result is favorable, and be able to bear or endure saline mist can amount to 2000 H, be in all sorts of plastic an adherent power performance that attends with aluminium alloy material is superior.
In the meantime, use coating of ability in swimming the other position that goes up as the plane coating and the research that regard functional sex as coating and make also be in advance ceaselessly ahead. The network latex that our country researcher wears with 3 yuan of polymer each other is made base makings, auxiliary in order to get together mica of ammonium phosphate, thin silk, silicon is aluminous base hollow small bead, chloridize olefin as for filling, development went a kind to be able to be used in the coating of damp of ability in swimming of plane wall housing. Its film is had decrease exceedingly goodly brace up fall a confusion of voices, flame retardant, heat insolation is sound-absorbing and equivalent if really, and harmful to human body organic volatile (namely VOC) content is very low.
In market of civil and unmanned aircraft, because what produce,Beijing Wei adds company of unmanned aircraft science and technology some model unmanned aircraft nose and wing use base material of special high strenth bubble, its data cannot bear suffer solvent, and solvent coating adds exert oneself to differ. The third of ability in swimming that chose to having good adhesion with base material then gets together face lacquer, use air spray.
Be in abroad, the Boeing company of United States of company of on eye preexistence bound two big aircrafts (Boing) the empty customer firm with France (the coating of ability in swimming that the aircraft that Airbus) place makes uses basically originates PPG company of the United States, company of Dutch Akzo Nobel. The sort of coating of aviation of ability in swimming that this two big companies produce is all ready, oxygen of the copy that includes type of face lacquer, polyurethane, annulus, be bored with child etc, quality has safeguard, applicability is very strong, can satisfy the user standard of each country, wide application is used at each countryman and on martial aviation equipment. If be used at the priming paint of plane envelope, PPG company has EWDE072/EWDE02 of priming paint of oxygen of lake be surrounded by mountains and the oxygen of lake be surrounded by mountains that do not have chromium priming paint EWDY048/EWAE118 two breed. The coating of aviation of ability in swimming of the Aerowave series that the Akzo Noble firm that empty customer firm uses produces, include anticorrosive lacquer of priming paint, face, the result is favorable, satisfied use requirement already, also achieved environmental protection to expect the result safely. Bottleneck
Put the issue that be in at present
Although besmear of ability in swimming installs a technology to be mixed in ceaseless development,perfect, but at present home still is existing in domain of coating of aviation of ability in swimming a few problems and technical bottleneck, orgnaization of need scientific research and plane make a firm collective thrash out. Besides before system of mentioned standard of coating of aviation ability in swimming is not quite perfect, have certain difference with abroad besides, still put in the following problem:
1) manufacturing cost is relative taller. As a result of the technology inside the industry, produce can relevant limitation, cost of coating of ability in swimming is at present higher, the paint that major uses at the price of coating of ability in swimming of aviation domain to also compare a tradition is opposite taller.
2) the good and bad are intermingled inside the industry. The manufacturer of coating of ability in swimming of our country is not much, product quality is uneven also, the coating of ability in swimming of aviation of high grade home that just proves via obtaining the practice that popularizes extensively the result is favorable is opposite less.
3) taller to carrying conduit to ask. Coating of ability in swimming is certain to besmearing the equipment of outfit also is had caustic, this lacquer can to duct generation is corroded and dissolve, the particle of decentralize gradually separate out, film also can produce hemp drop. The equipment that carries coating of ability in swimming so asks to collect appliance to have anticorrosion or the material of stainless steel, such coming down, facility cost is higher.
4) spray environment needs to transform upgrade. When producing the spot to need to have technology of spray of coating of ability in swimming, traditional paint spray product line needs to undertake be transforminged accordingly upgrading. Coating of ability in swimming is affected in besmear outfit process by the environment opposite bigger, opposite also to the control of temperature and humidity relatively strict, these are the elements that need to transform the consideration when upgrading in product line.
