Jiangsu Aokai Cov Khoom Tshiab, cov chaw tsim khoom ntawm PTFE high-temperature tape, qhia cov kev taw qhia kev tshaj lij. Thaum siv rau hauv lub tshuab nqus tsev, lub tshuab nqus tsev kho cua sov thiab lwm qhov chaw nqus tsev, PTFE daim kab xev kub kub muaj ntau qhov sib txawv ntawm cov tub ntxhais kawm ua tau zoo piv nrog rau cov ntawv thov hauv huab cua. Tsawg outgassing, tsawg volatile emissions thiab siab huv yog qhov tseem ceeb tshaj plaws. Cov ntsuas tseem ceeb uas yuav tsum tau ntsuas yog teev hauv qab no:
1. Vacuum Outgassing Property (Qhov taw qhia tseem ceeb tshaj) Qhov no yog qhov kev txiav txim siab ua tau zoo rau kev siv lub tshuab nqus tsev. Nyob rau hauv qhov tsis tshua muaj siab thiab kub siab, daim kab xev yuav tso tawm cov pa roj, uas degrades lub tshuab nqus tsev degree. Condensed volatiles contaminates optical Cheebtsam, sputtering lub hom phiaj thiab workpieces, ua rau pos huab txheej, tsis zoo zaj duab xis adhesion thiab txawm tag nrho cov khoom tsis kam lees.
· Tag Nrho Cov Poob Poob (TML): Kev xav tau dav dav TML ≤ 1.0%; Cov ntawv thov siab xws li aerospace thiab optical industries thov TML ≤ 0.5%.
· Sau Cov Khoom Siv Hluav Taws Xob (CVCM): Kev tswj nruj, ib txwm CVCM ≤ 0.1%; ultra-rigid scenarios xav tau CVCM ≤ 0.01%.
2. Qib Resistance Kub · Kev pabcuam kub tsis tu ncua: PTFE-coated fiberglass substrate ntawm PTFE daim kab xev tuaj yeem tiv taus ntev ntev ntawm 260 ° C. Txawm li cas los xij, qhov kub tsis kam ntawm cov nplaum txheej yuav tsum tau txheeb xyuas ib txhij. Cov pa silicone PSA muaj qhov kub tsis tu ncua nyob ib puag ncig 200 ° C, thaum ua haujlwm siab silicone nplaum tuaj yeem ncav cuag 260 ° C.
· Lub sij hawm luv luv ncov kub: Tshawb xyuas seb qhov kub siab tshaj plaws thaum lub sij hawm ua tiav tshaj daim kab xev lub sij hawm luv luv thermal txwv (feem ntau ≤300 ° C). Tshaj kub yuav carbonize thiab decompose cov nplaum txheej, ua rau muaj kab mob loj heev hauv lub tshuab nqus tsev chamber. Lus Cim: Yog tias lub tshuab nqus tsev kub kho qhov kub siab tshaj 260 ° C, PTFE daim kab xev yuav tsis siv ntxiv lawm; polyimide (Kapton) daim kab xev los yog aluminium foil daim kab xev yuav tsum tau saws hloov.
3. Adhesive Type & High-Tsub Tuav Lub Hwj Chim · Adhesive system xaiv: Silicone siab-rhiab nplaum nplaum yog lub ntsiab kev xaiv rau lub tshuab nqus tsev daim ntaub ntawv vim nws superior tshav kub. Txawm li cas los xij, cov nplaum silicone zoo tib yam muaj ntau cov siloxanes uas tsis tshua muaj molecular, uas ua rau muaj kev kub ntxhov hauv lub tshuab nqus tsev kub thiab paug cov khoom ua haujlwm, tshwj xeeb tshaj yog cov chaw kho qhov muag thiab cov chaw sib cuag hluav taws xob. Yog li ntawd, tshwj xeeb purified low-outgassing silicone nplaum los yog non-silicone nplaum formulations yuav tsum tau.
· Kub-kub tuav lub hwj chim: Nyob rau hauv lub tshuab nqus tsev ua ke thiab high-temperature tej yam kev mob, creep, ntug lifting los yog tag nrho tev ntawm daim kab xev yuav ncaj qha thaiv lub tshuab nqus tsev pipelines thiab qhia cov tshiab cov ntaub ntawv. Lub sij hawm shear tuav ntawm kev ua haujlwm kub yuav tsum raug lees paub.
4. Kev huv huv & Ionic paug · Cleanroom compatibility: Daim kab xev yuav tsum tsis muaj fiber ntau shedding thiab lint ntawm tej npoo. Cov kab xev tsim nyob rau hauv cov chaw huv huv yog nyiam.
· Cov ntsiab lus ionic tsawg: Rau cov txheej txheem nqus tsev hauv semiconductor thiab MEMS industries, halogen ions (Cl) thiab hlau ions (Na, K) muaj nyob rau hauv daim kab xev yuav precipitate ntawm kub kub, corroding circuits los yog altering doping concentration. Thov ionic extractables test report los ntawm cov neeg muag khoom.
· Zero silicone roj migration: Sib nrug los ntawm condensable volatiles, cov roj silicone dawb hauv cov nplaum yuav nkag mus rau ntawm qhov chaw thiab ua rau tsis ua hauj lwm hauv kev sib txuas thiab cov txheej txheem txuas ntxiv. Qhia rau xoom silicone roj migration qib rau cov ntawv thov tseem ceeb.
PTFE inherently yog cov khoom siv hluav taws xob siab. Static charges yooj yim accumulates ntawm nws nto los ntawm kev sib txhuam los yog tev tawm hauv lub tshuab nqus tsev chamber. Electrostatic tawm tuaj yeem ua rau cov khoom siv hluav taws xob puas tsuaj lossis nyiam cov pa phem.
· Qhov taw qhia yuav tsum tau: Rau shielding thiab tiv thaiv ntawm electrostatic-sensitive aav, anti-static PTFE daim kab xev yog yuav tsum tau nrog nto resistivity xws li ntawm 10⁶ ~ 10⁹ Ω / sq, thiab ruaj khov anti-static kev kawm yuav tsum tau khaws cia tom qab high-kub raug.
6. Plasma & Tshuaj tiv thaiv · Plasma tsis kam: Hauv sputtering thiab PECVD cov txheej txheem, daim kab xev raug rau plasma cua yuav raug etched, tso tawm fluorine dawb radicals uas ua paug cov yeeb yaj kiab tso thiab ua rau lub tshuab nqus tsev vacuum. Ntsuam xyuas kev siv tau ua ntej, lossis hloov mus rau ntau dua plasma-resistant polyimide daim kab xev yog tsim nyog.
· Tshuaj tiv thaiv: Cov roj seem vapor thiab ntxuav cov kuab tshuaj yuav muaj nyob rau hauv lub tshuab nqus tsev kho cua sov; ob lub nplaum thiab substrate yuav tiv thaiv o thiab tshuaj tiv thaiv.
7. Dimensional Stability & Thermal Shrinkage Rate Cov thermal shrinkage ntau dhau ntawm qhov kub siab yuav nthuav tawm cov npoo npog los yog tsim cov nplaum nplaum, ua rau lub ntsej muag npog qhov tseeb thiab kev sib haum xeeb.
· Qhov taw qhia qhov yuav tsum tau muaj: Saib xyuas cov ntaub ntawv thermal shrinkage muab los ntawm cov tuam ntxhab (kuaj tom qab 30 feeb ntawm 260 ° C). Premium nqus-qib daim kab xev ua tiav shrinkage hauv qab 2% lossis qis dua.
Summary of Selection Recommendations Thaum muas PTFE high-temperature daim kab xev rau lub tshuab nqus tsev ib puag ncig, kub kuj ib leeg yog tsis txaus. Thov ASTM E595 outgassing test reports los ntawm cov neeg muag khoom, kom meej meej lub xeev lub tshuab nqus tsev cov kev pab cuam thiab thov tshwj xeeb uas tsis muaj-outgassing tapes nrog purified silicone nplaum. Rau cov txheej txheem tsim khoom tseem ceeb, ua qhov kev sim daim coupon me me los ntsuas qhov kev hloov pauv ntawm ib feem ntawm lub tshuab nqus tsev vacuum thiab ntsuas qhov muaj peev xwm paug rau cov khoom tiav.
