High-tensile PTFE phahameng-mocheso lesela e entsoe ka tlotsa PTFE holim'a phahameng-matla fiberglass lesela, fana ka tensile matla, mocheso ho hanyetsa, bao e seng khomarela thepa, lik'hemik'hale ho hanyetsa, le tlaase kgohlano. Ditirišo tše bohlokwa di akaretša: go fetišetša ka intasteri (go phuthela ka go fokotša phišo, go baka dijo, diomiši tša lešela, go omiša pampiri/filimi); motswako bōpa lokolla lesela le chesang tobetsa cushion liners; welding dikgaretene tšireletso le mogote kwahelang baki; enjene motlakase le transformer kwahelang; go aga dibering tše di thelelago le dithekgo tša diphaephe; dikhemikhale filtration le belofo tiiso ka ditikoloho corrosive. Matla a godimo a go goga a netefatša go swarelela ka fase ga kgatelelo, go gagoga, go koba gape le gape, le kgatelelo ya motšhene ya themperetšha ya godimo go ralala le dikgopelo tše tše di fapanego tša mošomo o boima.

Nakong ya go sintering, dikarolwana tša PTFE godimo ga lešela la fiberglass di a qhibidiga ka godimo ga 327°C, di senya di-lamellae tša mathomo tša ketane ye e phuthilwego le mellwane ya dikarolwana go bopa go qhibidiga ga amorphous. Ge e fodile, PTFE e recrystallizes go ba spherulites yeo e bopilwego ka di-lamellae tše di lebanego le radially, ka crystallinity yeo e lego go 50-70%. Sekhahla sa go fodiša se laola phethego ya kristale: go fodiša ka go nanya go tšweletša kristale ye e phagamego, di- spherulite tše kgolo, go thatafala mo gogolo; go tima ka lebelo go fa spherulites ye botse le go fetofetoga mo go kaonafetšego.

Se se kopana sa setegeniki go tšwa go Jiangsu Aokai se sekaseka ka moo dithemperetšha tša fase ka mo go feteletšego goba tša godimo tša sintering di senyago lešela la themperetšha ya godimo ya PTFE. Go sintering ga fase go tlogela dikarolwana di sa qhibidige, go hlola micro-pores, kgokagano ye e fokolago ya go tlotša-substrate, bokagodimo bjo bo makgwakgwa, maatla a motšhene a mabe, le ponagalo ye e sa bonagalego ya maswi. Go fiša kudu go hlohleletša go senyega ga phišo ya PTFE, go tšweletša mekoti ya diphini, di-bubble, go brittleness, go fetoga ga mmala o mosehla go ya go o motsothwa le go lokolla muši o nago le mpholo. Bobedi bjo bo feteletšego bo senya go kopana, tshepedišo ya go se kgomarele, go feto-fetoga le maemo, go thibela go fiša le go tsepama ga ditekanyo.

PTFE phahameng-mocheso lesela insulating gaskets kopanya phahameng dielectric matla (a tsitsitseng tlas'a mongobo), -70 ° C ho 260 ° C mocheso fapaneng, bokahohleng lik'hemik'hale ho hanyetsa (ntle le qhibilihile alkali tšepe), bao e seng khomarela holim (thibela creepage),-ba khahlanong le creep (fiberglass matlafatso vs. hloekileng PTFE), phahameng tensile matla, tlaase khohlano (μ = 0.05-0.1), le V-0 tekanyetšo ya kgabo. Ge e bapetšwa le mica, rabara, le di-gasket tša PTFE tše di hlwekilego, lešela la PTFE le nea go feto-fetoga mo go phagamego, go šongwa, le go tsepama ga tekanyo ya nako e telele. Loketseng bakeng sa transformers, enjene kwahelang, lik'hemik'hale flange tiiso, le semiconductor thepa.

PTFE lesela bataletse nakong sintering hloka tsitsipano e nepahetseng, mocheso, le taolo ya thibelo. Mekgwa ya motheo: mochine wa stenter (dipoleiti tša diphini di boloka bophara, di thibela go fokotšega ga weft), profaele ya themperetšha ya gradient (go ruthetša ka go nanya → 380-400°C swara → go fodiša ka go nanya ka fase ga 310°C pele o lokolla kgatelelo), substrate yeo e fokotšegilego pele (e tloša kgatelelo ya go loga pele ga go tlotša), le botenya bja go tlotša bjo bo swanago (e thibela go qhibidiga ga phapano). Thibelo ya stenter e swanetše go hlokomelwa go fihlela e fodile ka fase ga ntlha ya kristale ya PTFE (e ka bago 310°C) go thibela warpage.

Coating go swana nakong ya PTFE emulsion impregnation ya fiberglass lesela ke lifeline ya boleng sehlahiswa. Go tlotša mo go sa lekalekanego go baka: go palelwa ga go se kgomarele (go kgomarela matheba a masesane), go fokola ga motšhene (go tsepama ga kgateletšego, go gagoga), go se tsepame ga mohlagase (gagamalo ya go thubega e theoga go fihla go 1/10), go tsenelela ga dikhemikhale (go tšhilafala ga pinhole), ditaba tša ditekanyo (go sotha), le diphošo tša go šoma (go lelera ga lebanta, go fapana ga botenya). Go tlotša ka go swana go nyaka taolo ye e nepagetšego ya viscosity ya emulsion, diteng tše di tiilego, kgatelelo ya lešela, dikgoba tša go pitlela, le diprofaele tša go omiša/sintering tša mafelo a mantši.

Lešela la themperetšha ya godimo ya PTFE le feta ka gare ga dikgato tše nne tša phetogo ya sebopego ge themperetšha e hlatloga: ka fase ga 260°C – go phatloga ga micro-go nanya le go fetofetoga ga tlaleletšo ya mašaledi; ka 327°C (ntlha ya go qhibidiga) – phetogo ya kristale go ya go amorphous, go tlotša go a nolofala, go delaminates go tšwa go fiberglass; 400-500°C – PTFE e depolymerizes (e lokolla dikgase tše di nago le mpholo), go tlotša go a nyamelela; ka godimo ga 500°C – fiberglass e a nolofala (840°C ntlha ya go nolofala) gomme e lahlegelwa ke botshepegi bja sebopego. Dula ka fase ga 260°C o tšwela pele, efoga ditlhora tša >300°C bakeng sa tšhomišo ye e bolokegilego.

PTFE phahameng-mocheso lesela e hlahiswa ka e ka ba e le 'ngoe-ina impregnation (e mong feta: ka potlako, theko e tlaase, tšesaane tlotsa, makgwakgwa holim le pinholes) kapa multi-ina impregnation (2-3 + feta: boreleli, teteaneng, pinhole-free tlotsa, PTFE dikahare 50-70%, tshebetso premium, theko e phahameng). Single-dip sutu di-gasket tša maemo a tlase, mepete ya nakwana le didirišwa tšeo di hemago. Multi-dip e a nyakega bakeng sa matlakala a go baka a maemo a dijo, mapanta a go sepetša ao a sa kgomaretšego, di-substrate tša potologo ya maqhubu a magolo, di- liner tša dikhemikhale le dimembrane tša go aga.

PTFE phahameng-mocheso lesela bokagodimo kalafo roba dikhemikhale inertness bakeng sa bonding / khatiso. Mekgwa e mene: etching lik'hemik'hale (sodium-naphthalene, matla a holim'a 20 → 40-50 dyn / cm, lera lefifi la sa feleng, sebopeho micro-porous), kalafo ea plasma (nano-roughening, grafting sehlopha se sebetsang, fensetere e khutšoanyane mafolofolo), kalafo corona (tšesane-filimi, ho bola ka potlako, botebo lekanyelitsoeng), le kalafo laser (nepahetseng micro-patterning, laoloa carbonization). Mekgwa ka moka e roughen mmeleng le ka dikhemikhale e tsebagatša dihlopha tša polar (C = O, -OH, -COOH) go kgontšha kgokagano ya sekgomaretši.

Bohloeki bja dilo tše tala ke motheo wa motheo wa boleng bja lešela la themperetšha ya godimo ya PTFE. Ditšhila (di-initiator tša mašaledi, didirišwa tša go šoma godimo ga mmu, di-ion tša tšhipi, didirišwa tša go lekanyetša bogolo tše di šilafetšego) di hlola go senyega ga phišo pele ga nako (dibubble, go tšholla makhopho ka godimo ga 260°C), bokagodimo bjo bo sa lekalekanego bjo bo sa kgomaretšego (dintlha tša ankora tša go kgomarela), go fokotšega ga go thibela motlakase (tahlegelo ya dielectric, gagamalo ya go thubega ya fase), maatla a metšhene ao a fokolago (go tsepama ga kgateletšego, go phatloga), le go serolane/go fetoga ga mmala. Didirišwa tše tala tša bohlweki bjo bo phagamego di netefatša lešela la PTFE leo le obamelago FDA, leo le phelago nako ye telele, leo le šomago gabotse.
