Itheyiphu ye-PTFE egoqiwe ingathuthukisa ukunamathela kwe-interlayer (ukuvimbela) kanye nokudlulisa okunamathelayo ngesikhathi sokugcina isikhathi eside. Izimbangela: inkumbulo enwebekayo yefilimu ye-PTFE kanye ne-silicone PSA ihamba ngaphansi kwengcindezi/ukushisa. Ukuvimbela: i-gradient winding tension (impintshana yangaphandle, ukuxega kwangaphakathi) ngesikhathi sokukhiqiza, kanye nokukhulula okokunamathela ohlangothini olunganamatheli. Gcina ku -15°C kuya ku-40°C, 30-70% RH, uvundlile kumarack, zungezisa amaroli ngekota. Ukuze uthole amamaki anamathelayo aminyene, engeza iphepha lokukhulula phakathi kwezendlalelo.

Indwangu ye-PTFE enezinga eliphezulu lokushisa inikeza izinzuzo eziyisithupha ezibalulekile njengebhande lokuthutha eliphrintayo: indawo engeyona induku (okunamathiselwe kokuphrinta nokukhishwa kukayinki ngokuhlanzekile), ukumelana nokushisa okungu-260°C (ukoma okusebenzayo), ukuzinza kwe-dimensional (<0.5% ubude, ukubhaliswa okunembile), ukungabi namandla kwamakhemikhali (imelana nokunamathisela okubolayo), ukungqubuzana kombala okuphansi, ukungqubuzana kombala ophansi, ukungqubuzana kombala, kanye nokusebenza okuqinile I-antistatic). Ilungele ukuphrinta isikrini, ukuphrinta kwedijithali, nezinhlelo zokusebenza zokudlulisa ukushisa.

Indwangu ye-PTFE ye-Anti-static izinga lokushisa eliphezulu ihlanganisa okunganamatheli, ukumelana nokushisa (260°C), kanye nezakhiwo ezingasebenzi ngamakhemikhali ze-PTFE ezijwayelekile nokusebenza kwe-static-dissipative. Izicelo ezibalulekile: ukukhiqizwa kwe-elekthronikhi (i-PCB lamination, ukuphathwa kwengxenye), i-PV module lamination (ivimbela ukulimala kwe-ESD kumaseli elanga), ukucubungula ukudla kanye nemithi (i-ESD-safe baking liners), izitshalo zamakhemikhali (anti-corrosion, anti-static ducting), kanye nezimboni zendwangu / zokunyathelisa. Ukumelana nobuso ngokuvamile 10⁶–10⁹ Ω.

Amateyipu e-PTFE okushisa okuphezulu agcinwe efomini lokugoqa angahlushwa ukunamathela kwe-interlayer (ukuvinjwa) kanye nokudluliselwa okunamathelayo ohlangothini olunganamathele. Imbangela: PTFE ifilimu inkumbulo nokunwebeka futhi abicah PSA creep ngaphansi kwengcindezi nokushisa. Isixazululo: I-gradient winding tension - iqinile ezingqimbeni ezingaphandle, iyaxega ezingqimbeni zangaphakathi - kusetshenziswa isilawuli sokuqina sokuqina kwe-loop. Ihambisana ne-coating yokukhishwa, isitoreji esifanele (15-40°C, 30-70% RH), ukubekwa okuvundlile, nokuzungezisa kwekota.

Impilo yesevisi yendwangu yokushisa ephezulu ye-PTFE iyahluka kakhulu ngohlelo lokusebenza. I-Chemical anti-corrosion lining ingahlala iminyaka engu-3+ (4x ubude kunerabha). Amathreyi okubhaka ukudla ezinyangeni ezedlule anokonakala okuncane. Amabhande e-Industrial conveyor agqoka kusuka ku-friction. I-PV lamination (150°C, EVA contact) inempilo emaphakathi. Izinhlelo zokusebenza zokungqubuzana okukhulu (amadiski abrasive) anokuphila okufushane. Izici ezibalulekile: ukulawulwa kwezinga lokushisa (hlala ku-≤260°C), gwema ama-creases abukhali, ukuhlanzwa okuvamile, nokushintshwa okufika ngesikhathi lapho kunamabhamuza noma kubaphuzi.

Itheyiphu yezinga lokushisa eliphezulu ye-PTFE esetshenziswa ekuthintaneni nokudla kufanele ihloniphe imikhawulo eqinile yezinga lokushisa: ≤260°C ukuze isetshenziswe ngokuqhubekayo (akukho mkhawulo wesikhathi), 260-300°C kufika kumaminithi angu-30 kuphela, futhi >300°C kunqatshelwe. Itheyiphu eyokuthintana nabantu abangaqondile kuphela (ama-tray liners, amakhava okushisa), hhayi ukugoqa ukudla okuqondile. Ungalokothi usebenze ngaphandle komthwalo wokudla (ukushisa okomile). Shintsha uma enamabhamuza, aphuzi, noma agugile.

Indwangu ye-PTFE ephezulu lokushisa (PTFE-coated fiberglass) ihlala isikhathi eside uma igcinwe ngaphansi kuka-260°C, kude namacrease acijile, futhi ihlanzwa ngamathuluzi athambile. Izici eziyinhloko ezikhawulela ukuphila: ukuwohloka kokushisa okungaphezu kuka-260°C, ukushaqeka okushisayo okuvela ekushiseni ngokushesha/okupholisa, ukukhathala komshini ngenxa yokugoba nokushuba, ukuhlasela kwamakhemikhali okuvela ezinsimbi ezincibilikisiwe ze-alkali noma ama-oxidizers aqinile, umonakalo ovela kuma-metal scrapers ngesikhathi sokuhlanza, kanye nokuchayeka kwe-UV ukuze kusetshenziswe ngaphandle. Ikhwalithi yokugqoka kanye ne-substrate nayo ibalulekile.

Indwangu ye-PTFE enezinga eliphezulu lokushisa izinzile kufika ku-300°C, kodwa emlilweni iyabola futhi ikhiphe amagesi anobuthi obukhulu: i-hydrogen fluoride (HF) (i-corrosive, pulmonary edema) ne-perfluoroisobutylene (PFIB) (ayinambala, ayinaphunga, ~10x ubuthi obungaphezu kwe-phosgene, i-nodo). Futhi i-carbon monoxide, izinsalela ze-PFOA, kanye ne-trace dioxins. Izifihla-buso zentuthu ezivamile azisebenzi; sebenzisa izisetshenziswa zokuphefumula ezizimele (SCBA). Izimpawu zingase zibambezeleke.

Izinamathiselo ezizwela ukucindezela kwe-Silicone (PSA) zamateyipu we-PTFE wezinga lokushisa eliphezulu ziyahlukahluka kakhulu ekusebenzeni kokuguga okuphezulu kwezinga lokushisa. I-Methylphenyl silicone PSA igcina >85% amandla ekhasi ngemva kwezinsuku ezingu-250°C/7, kuyilapho uhlobo lwe-methyl olujwayelekile lwehla luye ku-50-70%. Izinhlelo ze-addition-cured (hydrosilylation) zinikeza ukuzinza okungcono kakhulu kunokwelashwa nge-peroxide. Ngesevisi eqhubekayo engu-200°C+, khetha amamaki e-phenyl aphezulu alaphelwe ngokwengezwa.

Amateyipu e-PTFE anamathela ngokushisayo (i-PSA) kufanele aqhube ukushisa ngenkathi enamathela. Ukwengeza ama-filler kuthuthukisa ukuqhutshwa kokushisa kodwa kulimaza ukunamathela. Ibhalansi ekahle isebenzisa izinhlayiya eziyindilinga ezimahhadla (njengohlaka lwamathambo) oluhlanganiswe nezinhlayiya ezinhle (ukugcwalisa izikhala), okugcina isamba silayishwa ngaphezu nje komkhawulo we-percolation. Gwema ama-flakes nama-fibers; babulala i-tack.
