Izinhlobo Nezimo Zokwelapha Okubi kwe-Ultraviolet

Kuvame ukuba nezimo ezihlukahlukene zokuqiniswa kubuchwepheshe bokwelapha be-UV. Okuvame kakhulu ezenzakalweni ezimbi yilezi ezilandelayo. Nokho, ngezinye izikhathi isizathu sokwelapha kabi siphelele. Ngamanye amazwi, ngezinye izikhathi isenzakalo esi-2 noma ngaphezulu esiqinisiwe senzeka ngesikhathi esifanayo emkhiqizweni ofanayo. Isixazululo esiqondile ukuxhumana nezisebenzi zezobuchwepheshe zabakhiqizi bama-resin e-UV, amalambu e-UV mercury, izinto zomkhiqizo, nemishini yokwelapha ye-UV kuqala, noma ukuthola ngokuphelele imbangela yangempela yento yokuqina. Isixazululo esisebenzayo. Umqondo wokuqiniswa okungekuhle, okubizwa ngokuthi ukuqina, kusho: okokuqala, asikho isimo sokuqina esiphelele, okungukuthi, isimo sokungaqini; okwesibili, isimo sokuqiniswa ngokweqile, okungukuthi, ukweqisa. Uma kwenzeka ukuqina, kuzoshiswa ukwelashwa, noma ukuguquka kokushisa kuzokwenzeka ngenxa yekhalori ephezulu yomgqomo wokuphulukisa. Uma ukwenzeka kwento engabonakali kungenxa yokuthi inhlaka ayiqini ngokuphelele, umkhiqizo uyanamathela, amandla okunamathela azoncishiswa kakhulu, noma isixazululo se-resin esingaqinisiwe ebusweni bomkhiqizo. 1. Ukushisa kwe-thermal deformation yomkhiqizo akunawo umthelela omningi ensimbi noma ngokhuni, kodwa uchungechunge oluncane lwepulasitiki lwemikhiqizo yefilimu noma yefilimu luzwela kakhulu ukushisa. Ama-calories azwela kakhulu, ngakho-ke kungashiwo ukuthi okubaluleke kakhulu emsebenzini wokuxazulula ukuguqulwa kokushisa komkhiqizo kulo mkhakha. I-1) Igagasi: Ukuguqulwa kwe-thermal kuyisiteji sokuqala. 2) I-Curl: Qala ukuguqulwa kwengxenye. I-3) Ukuncipha: ukuguquguquka okukhulu kwendawo. 4) Isigaba sokuqala se-Carbonization: zonke ziba phuzi, zibemnyama, futhi ukushisa okunamandla kuba kubi. 2. Nakuba umphumela wokunamathisela ubonakala usuqedile inqubo yokuphulukisa, umphumela wokunamathela phakathi kwezinto ezisetshenziswayo nokwemboza awulungile. Ingase iklwelwe ngesipikili noma ngohlamvu lwemali ngobumnene, ungqimba lokuphulukisa luzosulwa, futhi ukuhlolwa kwe-cross-cutting ngeke kuhlolwe. Izingxenye zeselula, izingxenye ze-LCD zokubonisa noma amafilimu, i-COG/BGA nezinye izingxenye ze-chip kufanele ziqine kakhulu. 3. Swaging, Bulging) Izinto zikamama ezidinga ukupendwa zifana nepulasitiki noma irabha, ezwela kakhulu ezintweni ezishisayo. Ingxenye yezinto zikamama noma inhlaka izovuvukala ngenxa yokushisisa lapho yelapha. , Kuzodala umcimbi wokushiswa kwezinto zomama noma i-resin. Ukwandiswa kokugoba kwangaphakathi nangaphandle kuqinile, futhi kwenzeka ama-bubbles avela ngaphakathi, ukuze ukubukeka ngemva kokuqina kungabonakali kuhle. Lolu hlobo olubi luvela efilimini yokubona kanye nomakhalekhukhwini okhombisa ukuqina okuyisicaba. 4. Ifilimu ye-Bubbling (Bubbling, Air Bubble), ifilimu yekhwalithi ephezulu namanye amafilimu anembayo, nakuba ukuqiniswa nokuhlanganisa kungaqedwa ngokugcwele, uma ukubheka ngesibonakhulu, uzothola ukuthi kukhona imifantu emincane ekhona. Isizathu saso asikakaphethwa, okubuye kube yinto yomkhiqizo omubi okunzima ukuyixazulula. Sikholelwa ukuthi lokhu kuwumphumela we-crystal ye-resin ekusatshalalisweni okuvundlile ngemva kokuba inhlaka iqinisiwe. 5. Ifilimu ye-Surface crack, ifilimu yekhwalithi ephezulu kanye nelinye ifilimu elinembayo. Nakuba ukuqina nokunamathela kungaqedwa ngokugcwele, uma ukubheka ngesibonakhulu, uzothola ukuthi kukhona imifantu emihle kanye nencane. Isizathu saso asikakaphethwa, okubuye kube yinto yomkhiqizo omubi okunzima ukuyixazulula. Sikholelwa ukuthi lokhu kuwumphumela we-crystal ye-resin ekusatshalalisweni okuvundlile ngemva kokuba inhlaka iqinisiwe. 6. Isenzeko sokuba phuzi yinto eyenzeka kakhulu lapho iqina ku-resin esobala. Unganciphisa ukwenzeka koshintsho oluphuzi kusukela ekungezeni izinguquko eziphuzi ekubunjweni kwe-resin ukuze unciphise isenzakalo sokushintsha okuphuzi. 7. Ukuphrinta kweyinki ye-glue engomisi yefilimu evame ukusetshenziswa izacile -izinto ezingakomisi zefilimu yilezi: i-polyethylene, i-polypropylene, i-polyester, i-polyvinyl chloride, i-polystyrene, i-polyolefin, njll. Kodwa umehluko wukuthi ifilimu ayimuncwe. Ngakho-ke, ukuphrinta kwefilimu akomisi i-glue ikakhulukazi isebenzisa izimpawu ze-UV ze-convex nokuphrinta okuthambile kwe-UV. Kodwa-ke, ngesikhathi sokuphrinta nokucutshungulwa, inkinga izinkampani eziphrinta ilebula ezivame ukubhekana nazo ukunamathisela okunganele kukayinki we-UV ebusweni befilimu. Ukuqiniswa kunomthelela omkhulu emandleni okwelula. Ngokukhula kokuphulukiswa kwe-adhesive, ukuminyana okuxhunywe esiphambanweni kuyanda, isilinganiso se-molecular mass of the cross-linking point siba sincane. Uma i-epoxy ne-polyurethane acrylics ididiyelwe, ukunamathela kuzothuthukiswa kakhulu.
