Xihloko lexi xi katsa swikombiso swa nkoka swa matirhelo ya thepi ya mahiselo yale henhla ya PTFE leyi tirhisiwaka eka ku peta hi vacuum, vutshunguri byo hisa bya vacuum na tindzhawu leti fanaka. Swilaveko swa nkoka swihambana swinene na matirhiselo ya xibakabaka: ku humesiwa ka gasi swina nkoka swinene (TML≤1%, CVCM≤0.1%; tigiredi ta aerospace/optical ti lava TML≤0.5%, CVCM≤0.01%); ku tiya ka mahiselo swifanele ku tiyisisiwa eka hinkwaswo swa PTFE substrate (260°C) na adhesive layer; silicone PSA leyi basisiweke hi ndlela yo hlawuleka leyi nga na gasi ya le hansi ya laveka ku sivela ku thyakisa ka siloxane; matimba yo khoma mahiselo yale henhla ya sivela creep na edge lifting; ku basa swilava leswaku kungavi na ku khuluka ka fibre xikan’we na ionic yale hansi; thepi leyi lwisanaka na static (ku tiya ka le henhla ka 106-109 Ω/sq) yi sivela ku onhaka ka ESD; ku lwisana ka plasma kufanele ku kamberiwa eka maendlelo ya sputtering/PECVD; kuhunguteka ka mahiselo ehansi ka 2% switiyisisa ku kongoma ka masking.

Xihloko lexi xi pimanisa ku vupfa ka mahiselo ya kamara na mahiselo ya le henhla ya xinamarheti lexi twaka ntshikelelo wa silicone xa thepi ya PTFE. Ku vupfa ka mahiselo yale henhla (120-180°C) swiendla ti dense crosslinked networks letingana matimba yo tiya ya cohesive, leswi sivelaka masalela ya adhesive endzhaku ko rhurhumela. Yi endla ti chemical anchoring bonds na PTFE substrates hiku tirhisa primer co-curing, leswi herisaka makhombo ya delamination. Ku vupfa ka mahiselo yale henhla switlhela swisusa ti low-molecular volatiles loko kungase rhumeriwa, leswi sivelaka ku bubbling xikan’we naku thyakisa oil ya silicone hinkarhi waku hisiwa kosungula.

Nkongomiso lowu wu katsa ku hlawuriwa ka thepi ya mahiselo yale henhla ya PTFE eka injection molding demolding na switirhisiwa swa anti-stick. Ku hlawuriwa loku sekeriweke eka mahiselo: ≤260°C eka tipulasitiki to angarhela (standard silicone PSA tape, 0.13-0.18mm); 260-300°C eka tipulasitiki ta vunjhiniyara ta mahiselo yale henhla yofana na PC, PA66, POM (xinamarheti xa silicone xa mahiselo yale henhla, 0.18-0.25mm); 300-400°C eka PEEK, LCP, PPS ekusuhi na switsutsumi swo hisa (thepi yo namarhela ya tsandzeka; tirhisa lapi ra PTFE leri nga riki na namarheta kumbe filimi ya PFA). Ku hlawuriwa loku sekeriweke eka switirhisiwa: switirhisiwa swa tacky swilava high-release pure PTFE surfaces; switirhisiwa leswi taleke hi nghilazi/minerali swi lava thepi yo tika ya 0.25mm+ leyi nga onhakiki; swiengeteri leswi onhaka swi lava xinamarheti lexi lwisanaka na tikhemikhali na substrate yo enta; switirhisiwa leswi nga na vuxiyaxiya bya static swi lava thepi ya anti-static black PTFE.

Lapi ra fiberglass leri pfanganisiweke na PTFE ri tirhisiwa ngopfu eka ku lulamisiwa ka rhaba hikokwalaho ka ku tiya ka rona, ku nga namarheli, na ku hlangana ka le hansi. Switirhisiwa swa nkoka swikatsa: ti release liners ta plate/vacuum vulcanization xikan’we naku vumba mathayere; mabandhi yo fambisa lama nga namarheliki ya swigayo leswi pfulekeke, tikhalendara ni tilayini to kufumeta; lapi ro hlanganisa ra vuhlayiselo bya rhaba leyi nga hetiwangiki ngopfu; ku khomiwa hi ndlela yo hlawuleka ka silicone na fluororubber; na titreyi ta oven to post-curing. Mimbuyelo yikatsa ku herisa ku namarhela ka mold, ku hunguta kutirhisiwa ka release agent, ku sivela ku phutsela ka roller, naku tiyisisa ku demolding hiku olova.

Mahiselo ya glass transition (Tg) ya silicone pressure-sensitive adhesive ya kwalomu ka -120°C – yale hansi swinene kutlula ti acrylic adhesives. Tg leyi yale hansi swinene yi hlayisa PTFE high-temperature tape yi olova naswona yi namarhela hambi kuri eka -70°C, leswi sivelaka ku pandzeka ka brittle xikan’we naku endla leswaku kuva na ku namarhela loku tshembekaka eka switirhisiwa swa cryogenic.

Ku hlawuriwa ka phepha ro humesa kumbe substrate ya filimi na xitirhisiwa xo humesa swi khumba hi ku kongoma ku tshamiseka ka vuhlayiselo na matirhelo ya ku rhurhumela ka thepi ya mahiselo ya le henhla ya PTFE. Xihloko lexi xi pimanisa PET vs. kraft paper substrates na silicone vs. fluorinated release agents, leswi ringanyetaka nhlanganelo lowunene wa zero-residue peeling xikan’we naku tshembheka ka nkarhi woleha.
