I-Jiangsu Aokai New Materials, umenzi oqeqeshiweyo we-PTFE tape yobushushu obuphezulu, wabelana ngesikhokelo sobuchule. Xa isetyenziswe kwi-vacuum coating, unyango lwe-vacuum ubushushu kunye nezinye iindawo zokufunxa, iteyiphu yobushushu obuphezulu be-PTFE ineemfuno zokusebenza ezingundoqo ezahlukileyo kakhulu xa kuthelekiswa nezicelo ze-atmospheric. Ukukhutshwa okuphantsi, ukukhutshwa okuphantsi okuguquguqukayo kunye nococeko oluphezulu zizinto eziphambili eziphambili. Iimpawu eziphambili eziza kuvavanywa zidweliswe ngolu hlobo lulandelayo:
1. IPropati yeVacuum Outgassing (Esona Salathisi Sibalulekileyo)
Esi sisalathiso sokusebenza esigqibekileyo sezicelo zevacuum. Ngaphantsi koxinzelelo oluphantsi kunye nobushushu obuphezulu, i-tape iya kukhulula i-gas eguquguqukayo, ethoba isidanga se-vacuum. Izinto eziguquguqukayo eziguquguqukayo zingcolisa iinxalenye zamehlo, iithagethi zokutshiza kunye nezinto zokusebenza, ezikhokelela ekugqunyweni kwenkungu, ukuncamathela kwefilimu okungekuhle kunye nokulahlwa ngokupheleleyo kwemveliso.
· I-Total Mass Loss (TML): Imfuno ngokubanzi TML ≤ 1.0%; izicelo ezikumgangatho ophezulu ezifana ne-aerospace kunye namashishini optical afuna i-TML ≤ 0.5%.
· Iqokelelwe i-Volatile Condensable Materials (CVCM): Ukulawulwa ngokungqongqo, ngokuqhelekileyo iCVCM ≤ 0.1%; Iimeko ezinzima kakhulu zifuna i-CVCM ≤ 0.01%.
2. IBanga lokumelana nobushushu
· Ubushushu benkonzo eqhubekayo: I-PTFE-coated fiberglass substrate ye-PTFE tape inokumelana nokuvezwa kwexesha elide kwi-260 ° C. Nangona kunjalo, ukuchasana kweqondo lokushisa kwe-adhesive layer kufuneka kuqinisekiswe ngaxeshanye. I-silicone ye-PSA eqhelekileyo inika ukuxhathisa ubushushu obuqhubekayo malunga ne-200 ° C, ngelixa i-adhesive ye-silicone esebenza kakhulu inokufikelela kuma-260 ° C.
· Iqondo lobushushu bexesha elifutshane: Khangela ukuba amaqondo obushushu akhawulezayo ngexesha lokucubungula adlula umda we-thermal wexesha elifutshane weteyipu (ngokubanzi ≤300 ° C). Ukushisa okugqithisileyo kuya kukhupha i-carbonize kunye nokubola kwe-adhesive layer, kubangela ukungcoliseka okukhulu ngaphakathi kwegumbi lokucoca. Qaphela: Ukuba ubushushu bonyango lwe-vacuum bungaphezulu kakhulu kwe-260 ° C, iteyiphu ye-PTFE ayisasebenzi; Itheyiphu ye polyimide (Kapton) okanye itheyiphu yealuminiyam iyakwamkelwa endaweni yoko.
3. Uhlobo oluncamathelayo kunye namandla okubamba ubushushu obuphezulu
· Ukukhetha inkqubo yokuncamathelisa: Isincamathelisi esine-silicone yoxinzelelo lolona khetho luqhelekileyo lwezicelo zevacuum ngenxa yokumelana nobushushu obuphezulu. Nangona kunjalo, i-adhesives ye-silicone eqhelekileyo iqulethe i-siloxanes eninzi ye-molecular low, eguqukayo phantsi kwe-vacuum yobushushu obuphezulu kwaye ingcolise iindawo zokusebenza, ngakumbi iindawo ezibonakalayo kunye neendawo zoqhagamshelwano zombane. Ke ngoko, i-adhesive ye-silicone ecocekileyo ecocekileyo ephuma ngaphandle okanye i-non-silicone i-adhesive formulations iyafuneka.
· Amandla okubamba amaqondo obushushu aphezulu: Phantsi kwevacuum edityanisiweyo kunye neemeko zobushushu obuphezulu, ukukhasa, ukunyuswa komphetho okanye ukupelwa ngokupheleleyo kweteyipu kuya kuthintela ngokuthe ngqo imibhobho yokucoca kunye nokwazisa imithombo emitsha yongcoliseko. Ubude bexesha lokubamba i-shear kwiqondo lokushisa lokusebenza kufuneka liqinisekiswe.
4. Ukucoceka kunye nokuNgcola kwe-Ionic
· Ukuhambelana kwegumbi lokucoceka: Iteyiphu ayisayi kuchithwa ifayibha kunye nentambo kwimida yokusika. Iiteyiphu ezenziwe kwiindawo ezicocekileyo zikhethwayo.
· Umxholo we-ionic ophantsi: Kwiinkqubo ze-vacuum kwi-semiconductor kunye ne-MEMS kumashishini, i-halogen ions (Cl) kunye ne-ioni yensimbi (Na, K) equlethwe kwi-tape iya kudlula kwiqondo lokushisa eliphezulu, i-corroding circuits okanye i-concentration yokuguqula i-doping. Cela iingxelo zovavanyo lwe-ionic extractables ezivela kubaboneleli.
· Ukufuduka kweoli ye-silicone ye-Zero: Ngaphandle kokuguquguquka okuguquguqukayo, i-oyile ye-silicone yasimahla ngaphakathi kokunamathelisa inokutyhutyha imiphezulu kwaye ibangele ukusilela kwiinkqubo ezilandelayo zokubopha kunye ne-welding. Cacisa ibakala lokufuduka kweoli ye-silicone ye-zero kwizicelo ezibalulekileyo.
I-PTFE ngokwemvelo yimathiriyeli ephezulu yokugquma. Intlawulo engatshintshiyo iqokelelana ngokulula kumphezulu wayo ngokukhuhlana okanye ukuxobula ngaphakathi kumagumbi okufunxa. Ukukhutshwa kwe-electrostatic kungonakalisa amalungu e-elektroniki abuthathaka okanye kutsale ungcoliseko.
· Imfuno yesalathisi: Ukukhusela kunye nokukhuselwa kwemimandla e-electrostatic-sensitive, i-anti-static PTFE tape iyafuneka kunye nokumelana nomphezulu ukusuka kwi-10⁶ ~ 10⁹ Ω/sq, kunye nokusebenza okuzinzile kwe-anti-static kufuneka kugcinwe emva kokuvezwa kobushushu obuphezulu.
6. I-Plasma & Ukumelana neMichiza
· Ukumelana ne-Plasma: Kwiinkqubo ze-sputtering kunye ne-PECVD, i-tape evezwe kwi-plasma atmosphere iya kufakwa, ikhuphe i-fluorine radicals yamahhala engcolisa iifilimu ezigciniweyo kunye nokutshabalalisa amagumbi okucoca. Vavanya ukufaneleka kwangaphambili, okanye utshintshele kwiteyiphu ye-polyimide ekwaziyo ukumelana neplasma ukuba kuyimfuneko.
· Ukunganyangeki kwemichiza: Umphunga we-oyile oshiyekileyo kunye nezinyibilikisi zokucoca zinokubakho ngexesha lonyango lwe-vacuum yobushushu; zombini i-adhesive kunye ne-substrate iya kuxhathisa ukudumba kunye neekhemikhali.
7. Uzinzo lweDimensional & Thermal Shrinkage Rate
Ukucutheka okugqithisileyo kwe-thermal kubushushu obuphezulu kuya kuveza imiphetho egqunyiweyo okanye kuvelise imibimbi encamathelayo, ukuphazamisa ukuchaneka kwe-mask kunye nokuhambelana.
· Imfuno yesalathisi: Hlaziya idatha yokuncipha kwe-thermal enikwe ngabavelisi (ivavanywe emva kwemizuzu engama-30 kwi-260 ° C). Iteyiphu yomgangatho wokufunxa wexabiso eliphezulu ifezekisa ukucutheka ngaphantsi kwe-2% okanye nangaphantsi.
Isishwankathelo seNgcebiso zoKhetho
Xa kuthengwa i-PTFE iteyiphu yobushushu obuphezulu bemekobume zevacuum, ukumelana nobushushu kukodwa akwanelanga. Cela ingxelo ye-ASTM E595 yokukhupha i-outgassing evela kubaboneleli, chaza ngokucacileyo iimeko zenkonzo ye-vacuum kwaye ufune iiteyiphu ezikhethekileyo ezikhupha umoya ophantsi kunye ne-adhesive silicone ecocekileyo. Kwiinkqubo zemveliso ezibalulekileyo, qhuba uvavanyo oluncinci lwekhuphoni ukulinganisa ukuguquguquka okungaphelelanga koxinzelelo kwi-vacuum gauges kunye nokuvavanya ungcoliseko olunokubakho kwiimveliso ezigqityiweyo.
