Sehlogo se se tsebagatša tshepedišo ya motheo ye e feletšego ya go kolobiša lešela la fiberglass ka emulsion ya PTFE. Megato ye šupa ya bohlokwa: 1 Tlhokomelo ya pele (go tloša boka/go tloša bogolo) ka 350-400°C go tloša didirišwa tša go dira bogolo bja lešela; 2 Emulsion tlhamo le 40-55% dikahare tiileng le surfactants bakeng sa ntlafatsoa kolobiša; 3 Impregnation ka mokgwa wa dip-squeeze kapa ngaka legare tlotsa; 4 Go omiša ka 100-150°C go moyafatša meetse ka bonolo le go bopa filimi ya PTFE ye e omilego; 5 Sintering ka 360-390°C (go fihla go 400°C) go qhibidiša dikarolwana tša PTFE go ba filimi ye e tšwelago pele; 6 Multi-potoloho impregnation-omisa-sintering pheta 2-4 makhetlo a ho fihlela sepheo botenya le resin dikahare (45-65%); 7 Kalafo ya ka morago go akaretšwa kalafo ya corona, go kgaola mošito, go sotha le go hlahloba boleng. Dintlha tša taolo ya motheo: dewaxing ka botlalo, go kolobiša ka botlalo ka emulsion, go omišwa ganyenyane-ganyenyane, themperetšha ya sintering ye e nepagetšego, le segokanyipalo sa go tlotša se se sa fetogego. Dihlahiswa sebeletsa phahameng-maqhubu a koporo-apere laminates, phahameng-mocheso conveyor mabanta le mehaho lera thepa.

Sehlogo se se tsebiša disolvent tša organic tšeo lešela la themperetšha ya godimo ya PTFE le ka di kgotlelelago. Lešela la fiberglass leo le tloditšwego ka PTFE le bontšha go se šome ga dikhemikhale mo go kgethegilego, le ganetša mo e nyakilego go ba disolvent ka moka tše di tlwaelegilego tša organic ka fase ga maemo a tlwaelegilego a mošomo ntle le go phatlalatšwa, go ruruga goba karabelo ya dikhemikhale. Dihlopha tše di kgotlelelwago di akaretša: di-alcohol (methanol, ethanol, isopropanol), di-ketone (acetone, MEK, cyclohexanone), di-ester (ethyl acetate, butyl acetate), dikhaponetaeoksaete (peterole, toluene, xylene, hexane), dikhaponetaeoksaete tše di nago le halogen (dichloromethane, chloroform, carbon tetrachloride), di-ether (diethyl ether, THF), diesiti tša organic (esiti ya asetiki ya leqhwa, esiti ya formic), di-amine le di-amide (triethylamine, DMF), di-phenol, le tše dingwe tša go swana le khapone disulfide, pyridine, oli ya silicone le seela sa diporiki.

Sehlogo se se akaretša dinyakwa tša seelo sa go tonya nakong ya go sintering ga lešela la themperetšha ya godimo ya PTFE. Ka morago ga go sintering ka 380-400°C, lešela le swanetše go feta ka lebelo ka lefelong la 310-315°C leo le nago le kwelobohloko ya kristale. Sekgahla sa go fodiša se se kgothaletšwago ke bonyane 30-50°C/min (lešela le lesesane le ka fihlelela 100-200°C/min ka go fodiša moyeng). Go fodiša ka lebelo (go tima) go tšweletša crystallinity ya fase (45-50%), go tšweletša dilo tše boleta, tše thata tša go tlotša ka bokagodimo bjo bo boreledi, go kgomarela ka maatla, tshepedišo ye botse kudu ya go se kgomarele, le go ganetša delamination le go phatloga. Go fodiša ka go nanya (go tonya ga sebjana) go feletša ka kristale ya godimo (60-70%), go hlola dikhupetšo tše di thata, tše di brittle tšeo di sekametšego go fokotšega, go ebola le go phatloga ga microcracks.

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 khomaretse thepa, lik'hemik'hale ho hanyetsa, le tlaase kgohlano. Ditirišo tše bohlokwa di akaretša: go fetišetša 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 tša go fapafapana 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 dilamellae 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.

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 tekanyo.

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 li 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 tonya 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 theogela 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 la 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 ka 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.
