Chizvarwa chitsva cheUV-kuporesa silicones uye epoxies zviri kuwedzera kushandiswa mumotokari uye zvemagetsi application.
Chiito chese muhupenyu chinosanganisira kutengeserana: Kuwanikwa kweimwe bhenefiti nekubhadhara imwe, kuzadzisa zvakanyanya zvinodikanwa zvemamiriro aripo. Kana mamiriro acho achibatanidza kusungirirwa kwepamusoro-soro, kuisa chisimbiso kana kuisa gasketing, vagadziri vanovimba nemanamira ekurapa eUV nekuti anobvumira pa-kuda uye nekukurumidza kurapa (1 kusvika 5 masekonzi mushure mekuratidzwa kwechiedza).
Kutengeserana, zvisinei, ndekwekuti izvi zvinonamira (acrylic, silicone uye epoxy) zvinoda substrate inoonekera kuti isungirire zvakanaka, uye inodhura zvakanyanya kupfuura zvinonamira zvinorapa nedzimwe nzira. Zvakadaro, vasingaverengeki vagadziri mumaindasitiri mazhinji vakagadzira ichi kutengeserana kwemakumi emakore anoverengeka. Mamwe makambani mazhinji achaita izvi kune ramangwana rinoonekwa. Musiyano, zvisinei, ndewekuti mainjiniya anozoita mukana wekushandisa silicone kana epoxy UV-kurapa inonamira, seimwe iri acrylic-yakavakirwa.
"Kunyangwe takagadzira UV-kurapa silicones kwemakore gumi apfuura kana zvakadaro, mumakore matatu apfuura taifanira kuwedzera kuedza kwedu kutengesa kuti tienderane nezvinodiwa nemusika," anodaro Doug McKinzie, mutevedzeri wemutungamiri wezvigadzirwa zvehunyanzvi kuNovagard. Solutions. "Kutengesa kwedu UV-kurapa silicone kwakawedzera makumi mashanu muzana makore mashoma apfuura. Izvi zvichaderedza vamwe, asi tichiri kutarisira kukura kwakanaka kwemakore anoverengeka anotevera.”
Pakati pevashandisi vakuru veUV-kurapa silicones vane mota OEMs, uye Tier 1 uye Tier 2 vatengesi. Mumwe mutengi weTier 2 anoshandisa Loctite SI 5031 sealant kubva kuHenkel Corp. kuenda kumateshi ehari mudzimba dzemagetsi mabhureki ekudzora mamodule uye matayi-pressure sensors. Iyo kambani inoshandisawo Loctite SI 5039 kugadzira UV-yakaporeswa-mu-nzvimbo silicone gasket yakatenderedza perimeter yega yega module. Bill Brown, maneja wezvishandiso zveinjiniya yeHenkel, anoti zvigadzirwa zvese zvine dhayi yefluorescent yekubatsira kuona kuvepo kwekunamira panguva yekuongorora kwekupedzisira.
Iyi subassembly inozotumirwa kune Tier 1 mutengesi iyo inoisa zvimwe zvemukati zvemukati uye inobatanidza PCB kumaterminal. Chivharo chinoiswa pamusoro peperimeter gasket kugadzira chisimbiso chakasimba pagungano rekupedzisira.
UV-kurapa epoxy adhesives zvakare anowanzo shandiswa kune mota uye yevatengi zvemagetsi maapplication. Chimwe chikonzero ndechekuti izvi zvinonamira, sesilicones, zvakanyatsogadzirwa kuti zvienderane newavelength ye LED light sources (320 kusvika 550 nanometers), saka vanogadzira vanowana zvese zvakanakira mwenje we LED, senge hupenyu hurefu, kupisa kushoma uye kuchinjika masisitimu. Chimwe chikonzero mutengo wakaderera wekurapa kweUV, nekudaro zvichiita kuti zvive nyore kumakambani kutengesa kusvika kune iyi tekinoroji.
