Maqaalkani waxa uu eegayaa saamaynta xakamaynta xiisadda webka inta lagu jiro daahan heerkul sare ah oo Teflon ah oo ku saabsan isku-duubnaanta substrate-ka PTFE iyo lebbiska dahaarka dhejiska ah. Saamaynta dhullanaanta substrate-ka: xiisadda dhaafta xadka laastikada waxay sababtaa fidinta caagga ah iyo luqunta aan laga noqon karin (dheeraynta dhererka, cidhiidhiga transverse), samaynta caajisnimo, laalaab iyo qaabab mawjad leh; PTFE oo ku gurguurta xiisad joogto ah waxay noqotaa 'barafsan' ka dib qaboojinta, taasoo keenta sinnaansho la'aanta dusha sare; Xiisad aan sinnayn oo aan sinnayn oo ka imanaysa isbarbar yaaca rullaluistu waxay abuurtaa cidhifyo qalloocan, finan dhexe, iyo calaamado dabacsan oo xilliyeed ah.

Maqaalkani wuxuu eegayaa isbeddelada qaabdhismeedka ee dharka heerkulka sare ee PTFE inta lagu jiro da'da. Afar arrimood: PTFE daahan microstructure - maqaarka silsilad molecular iyo oxidation (carbonyl/carboxyl kooxda formation), crystallinity isbedel (hore kor u kaca ka dibna dumo), micro-dillaac iyo pinhole formation, dusha budada; Substrate fiber galaas iyo interface - kala goynta wakiilka cabbirka/isku xidhka oo keenaya luminta isku xidhka, xidhidhaynta wejiga iyo delamination (caabuq, aagagga cad), nabaad guurka shabkada fiber-ka galaaska iyo nabaad-guurka, roobka birta alkali oo keena daxalka walaaca; Qaab dhismeedka macroscopic iyo muuqaalka - midabka isbeddelka (caddaan → beige → bunni → madow), qallafsanaanta iyo laallaabashada, rafashada dusha sare iyo luminta dhalaalka, budada marka la taabto, luminta dabacsanaanta buuxda. Nuxurka gabowga: geeddi-socod horumarsan oo ah 'hoos u dhigista dahaarka → fashilka interface → hoos u dhaca substrate.'

Maqaalkani waxa uu daboolayaa sida loo xakameeyo wakhtiga sinjiga ee dharka heerkulka sare ee PTFE. Habka xakamaynta xudunta ah: hagaajinta xawaaraha khadka. Waqtiga isku dhafka ah = qaybta kuleylka wax ku ool ah dhererka dhererka dharka. Heerkulka wax-ku-oolka ahi waa 350°C (heerkulkan ka sarreeya waxa lagu tiriyaa wakhtiga sintay). Heerkulka aagga badan ee qaybinta: preheating (100-250°C), sintering (360-395°C), dejinta heerkul sare (380-390°C), qaboojinta (ka hooseeya 300°C). Waqtiyada tixraaca ee 380-390 ° C: khafiif ah (0.08-0.13mm) 30-60 ilbiriqsi; heerka (0.18-0.25mm) 1.5-3 daqiiqo; culus (≥0.35mm) 3-5 daqiiqo. Aqoonsiga iyo hagaajinta: hoos u dhigista (xoogga hoose, daadinta budada, dildilaaca yar yar) → yareeyo xawaaraha si loo kordhiyo waqtiga; xad-dhaaf ah (jaalle, jajaban, qiiq cad) → kordhiso xawaaraha si loo gaabiyo degenaanshaha. Heerkulka-waqtiga u dhigma waxa ay ogolanaysaa in si degdeg ah kulkulkiisu sareeyo (395-405°C, ilbiriqsi) ama heerkul hoose oo tartiib tartiib ah (360-375°C, 5-8 daqiiqo).

Maqaalkani waxa uu qeexayaa qaabka isbeddelka xoogga isku-dhafka ah ee lakabka dhejiska heerkulka-sare ee PTFE ka dib gabow heerkul sare ah. Qaabka saddex-marxaladda ah: Marxaladda kor u kaca ee daawaynta ka dib (heerkulka hore ee heerkulka 200-260 ° C, kooxaha falcelinta hadhaaga ahi waxay sii wadaan isku-xirnaanta, isku-duubnida ayaa si weyn u kordheysa); Marxaladda dheellitirka xasilloonida (hababka is-dhaafsiga ee dhammaystirka, isku-xidhnaanta ayaa ah mid xasilloon muddo dheer); Hoos u dhaca iyo heerka hoos u dhaca (waqtiga xad-dhaafka ah/heerkulka ayaa keena hoos u dhaca silsiladda, isku xirnaanta ayaa hoos u dhacda, koollada ayaa jilcisa oo waxay noqotaa mid adag). Sababaha xididka ah ee fashilka wadajirka ah (dillaaca gudaha ee haraaga ka tagaya) iyo tuujin (qulqulka qabow ee ka imanaya geesaha sababtoo ah moodeelka oo yaraada) ayaa la falanqeeyay.

Maqaalkani wuxuu faahfaahinayaa codsiyada Teflon dharka heerkulka sare ee warshadaha tamarta qorraxda. Codsiga muhiimka ah ee lakabka moduleka: dharka lagu sii daayo ee lagu dhejiyay kor/hoosyada cutubyada PV waxay ka hortagtaa dhalaalidda EVA (140-150°C) inay ku dhegganaato kuleyliyaha saxan ama saxan caag ah, ilaalinta qalabka iyo hubinta dusha moduleka siman; suumanka kombuyuutarrada ee rarida/dejinta tooska ah; Dharka ilaalinta caagga ah oo fidinaya nolosha adeegga. Alxanka xadhkaha unugga: suunka qaadaha qaada ee sidda unugyo iyo ribbon dhexmara aagga kululaynta, oo leh dusha aan dhegta lahayn oo iska caabinaysa qulqulka iyo qulqulka alxanka; barkimooyin kuleyliyaha loogu talagalay goobaha shaqada ee alxanka.
