I-Jiangsu Aokai New Materials, umkhiqizi ochwepheshe we-PTFE itheyiphu yezinga lokushisa eliphezulu, wabelana ngeziqondiso zobungcweti. Uma isetshenziswa ku-vacuum coating, ukwelashwa kokushisa kwe-vacuum nezinye izindawo ze-vacuum, itheyiphu ye-PTFE enezinga eliphezulu lokushisa inezidingo zokusebenza ezihluke kakhulu eziwumongo uma kuqhathaniswa nezinhlelo zokusebenza zomkhathi. Ukukhipha umoya okuphansi, ukukhishwa okuguquguqukayo okuphansi kanye nokuhlanzeka okuphezulu yizinto eziza kuqala. Izinkomba ezibalulekile okufanele zihlolwe zihlelwe kanje:
1. I-Vacuum Outgassing Property (Inkomba Ebaluleke Kakhulu)
Lena inkomba yokusebenza ewujuqu yezinhlelo zokusebenza ze-vacuum. Ngaphansi kwengcindezi ephansi kanye nokushisa okuphezulu, i-tape izokhipha igesi eguquguqukayo, eyehlisa i-vacuum degree. Izivunguvungu ezijiyile zingcolisa izakhi ezibonayo, okuhlosiwe okufafaza kuzo kanye nezinto zokusebenza, okuholela ekumbozekeni kwenkungu, ukunamathela kwefilimu okungekuhle ngisho nokulahlwa okuphelele komkhiqizo.
· Ingqikithi Yokulahlekelwa Kwenqwaba (TML): Imfuneko evamile TML ≤ 1.0%; izinhlelo zokusebenza ezisezingeni eliphezulu njengezimboni ze-aerospace nezimboni zokubona zidinga i-TML ≤ 0.5%.
· Izinto Eziqoqiwe Eziguquguqukayo Eziqoqiwe (CVCM): Kulawulwa ngokuqinile, ngokuvamile i-CVCM ≤ 0.1%; Izimo eziqinile zidinga i-CVCM ≤ 0.01%.
2. Ibanga Lokumelana Nokushisa
· Izinga lokushisa lesevisi eliqhubekayo: I-PTFE-coated fiberglass substrate ye-PTFE tape ingamelana nokuchayeka isikhathi eside ku-260°C. Nokho, ukumelana kwezinga lokushisa kwesendlalelo sokunamathela kufanele kuqinisekiswe kanyekanye. I-siliconal silicone PSA inikeza ukumelana nokushisa okuqhubekayo okungaba ngu-200°C, kuyilapho okunamathelayo kwe-silicone esebenza kahle kakhulu kungafinyelela ku-260°C.
· Izinga lokushisa eliphakeme lesikhathi esifushane: Hlola ukuthi izinga lokushisa eliphakeme elisheshayo ngesikhathi sokucubungula liyawedlula yini umkhawulo wokushisa wetheyiphu wesikhathi esifushane (ngokuvamile ≤300°C). Izinga lokushisa eleqile lizokhipha ikhabhoni futhi libolise ungqimba olunamathelayo, kubangele ukungcoliswa okukhulu ngaphakathi kwegumbi le-vacuum. Qaphela: Uma izinga lokushisa lokuhlanza ivacuum lingaphezu kuka-260°C, itheyiphu ye-PTFE ayisasebenzi; Itheyiphu ye-polyimide (Kapton) noma itheyiphu ye-aluminium foil izokwamukelwa esikhundleni salokho.
3. Uhlobo Lwezinto Ezinamathelayo & Amandla Okubamba Amazinga Okushisa aphezulu
· Ukukhethwa kwesistimu enamathelayo: Ingcina ye-silicone ezwela ukucindezela iyindlela evamile yokukhethwa kwezicelo ze-vacuum ngenxa yokumelana kwayo nokushisa okuphezulu. Noma kunjalo, izinamatheliso ze-silicone ezijwayelekile ziqukethe ama-siloxane amaningi aphansi, aguquguqukayo ngaphansi kwe-vacuum enezinga eliphezulu lokushisa futhi angcolise izinto zokusebenza, ikakhulukazi izindawo ezikhanyayo nezindawo zokuthintana zikagesi. Ngakho-ke, i-adhesive adhesive adhesive adhesive ehlanzekile ephansi ngokukhethekile iyadingeka.
· Amandla okubamba amazinga okushisa aphezulu: Ngaphansi kwezimo ezihlanganisiwe zevacuum kanye nezinga lokushisa eliphezulu, ukukhasa, ukuphakamisa unqenqema noma ukuxebuka ngokugcwele kwetheyiphu kuzovimba ngokuqondile amapayipi okukhipha umoya futhi kwethule imithombo emisha yokungcola. Ubude besikhathi sokubamba i-shear ezingeni lokushisa lokusebenza kufanele buqinisekiswe.
4. Inhlanzeko kanye Nokungcola Kwe-Ionic
· Ukuhambisana kwegumbi elihlanzekile: Itheyiphu akufanele ichitheke i-fiber kanye nelanta emaphethelweni anqunyiwe. Amateyipu akhiqizwa ezindaweni ezihlanzekile ayakhethwa.
· Okuqukethwe kwe-ionic ephansi: Ngezinqubo ze-vacuum ku-semiconductor kanye nezimboni ze-MEMS, ama-ion we-halogen (Cl) nama-ion ensimbi (Na, K) aqukethwe kutheyiphu azokwehlela kumazinga okushisa aphezulu, amasekhethi okugqwala noma aguqule ukugxila kwe-doping. Cela imibiko yokuhlola okukhishwe kwe-ionic kubahlinzeki.
· Ukufuduka kukawoyela we-silicone engu-Zero: Ngaphandle kokuguquguquka okungaguquguqukayo, uwoyela we-silicone wamahhala ngaphakathi kwezinamatheliso angase adlulele ezindaweni futhi abangele ukwehluleka ezinqubweni ezilandelanayo zokuhlanganisa nokushisela. Cacisa ibanga lokufuduka likawoyela we-silicone elinguziro lezinhlelo zokusebenza ezibucayi.
I-PTFE ngokwemvelo iyisisetshenziswa sokuvikela okuphezulu. Ishaja engaguquki inqwabelana kalula endaweni yayo ngokusebenzisa ukungqubuzana noma ukuxebuka ngaphakathi kwamagumba e-vacuum. Ukukhishwa kwe-electrostatic kungalimaza izingxenye ze-elekthronikhi ezibucayi noma kuhehe izinto ezingcolisayo.
· Imfuneko yesikhombi: Ukuze kuvikelwe futhi kuvikelwe izindawo ezizwelayo ku-electrostatic, itheyiphu ye-PTFE engaguquguquki iyadingeka enokumelana nendawo okusukela ku-10⁶ ~ 10⁹ Ω/sq, nokusebenza okuzinzile kwe-anti-static kufanele kugcinwe ngemva kokuchayeka kuthempelesha ephezulu.
6. I-Plasma & Chemical Resistance
· Ukumelana ne-Plasma: Ezinqubweni ze-sputtering kanye ne-PECVD, i-tape evezwe emkhathini we-plasma izoqoshwa, ikhiphe ama-radicals mahhala e-fluorine angcolisa amafilimu adiphozithi futhi agugule amagumbi e-vacuum. Linganisa ukusebenza kusenesikhathi, noma ushintshele kutheyiphu ye-polyimide engazweli ku-plasma uma kudingeka.
· Ukumelana namakhemikhali: Umhwamuko kawoyela osalayo nezincibilikisi zokuhlanza kungase kube khona ngesikhathi sokwelashwa kokushisa kwevacuum; kokubili okunamathelayo kanye ne-substrate kuzomelana nokuvuvukala nokusabela kwamakhemikhali.
7. Ukuzinza Kwe-Dimensional & Thermal Shrinkage Rate
Ukuncipha okushisayo okudlulele kuzinga lokushisa eliphezulu kuzoveza imiphetho efihliwe noma kukhiqize imibimbi enamathelayo, kukhinyabeze ukunemba kokufihla kanye nokuvumelana.
· Imfuneko yenkomba: Buyekeza idatha yokushwabana okushisayo enikezwe abakhiqizi (ihlolwe ngemva kwemizuzu engama-30 ku-260°C). I-Premium vacuum-grade tape ifinyelela ukuncipha ngaphansi kuka-2% noma ngaphansi.
Isifinyezo Sezincomo Zokukhetha
Uma uthenga itheyiphu ye-PTFE yokushisa okuphezulu kwezindawo ze-vacuum, ukumelana nokushisa kukodwa akwanele. Cela imibiko yokuhlolwa kokukhipha umoya kwe-ASTM E595 kubahlinzeki, isho ngokucacile izimo zesevisi ye-vacuum futhi funa amateyipu akhethekile akhipha umoya omncane ane-adhesive asilicone ehlanzekile. Ngezinqubo zokukhiqiza ezibucayi, yenza ukuhlola kwekhuphoni kwezinga elincane ukukala ukuguquguquka kwengxenye yengcindezi kumageji e-vacuum futhi uhlole ukungcola okungaba khona emikhiqizweni ephelile.
