PTFE tepi ya mankhwala chitoliro/chiwiya odana ndi dzimbiri, osati ndodo, ndi kusindikiza chitetezo amafuna kufananitsa gawo lapansi, dongosolo zomatira, ndi mankhwala media. Silicone PSA ikulimbikitsidwa 200-260 ° C ndi zidulo / alkalis; acrylic PSA imalimbana ndi zosungunulira za organic koma imachepetsa kutentha mpaka ≤150°C. Pa HF, kuwira > 80% alkali, kapena chlorine trifluoride, gwiritsani ntchito PTFE-only lining (palibe zomatira organic). Zovuta: zomatira ndiye ulalo wofooka kwambiri, osati PTFE yokha.

Mphamvu ya tepi ya PTFE imapangidwa bwino kudzera pakuyala ndi kukhathamiritsa kwa njira yochiritsa. Kuphimba: zoyambira wosanjikiza (0.5-2μm silane primer kupewa zomatira peeling), zomatira makulidwe 30-60μm (mulingo woyenera kwambiri akugwira mphamvu), zingalowe defoaming, ndi 5-10μm kusefera. Kuchiritsa: Kutentha kwapang'onopang'ono (80-100 ° C kuchotsa zosungunulira → 120-140 ° C kuumba → 150-220 ° C deep crosslinking), post-curing (40-60 ° C kwa 24-48h kuti mupumule kupsyinjika), ndi kutsika kwapakati kuti muteteze kupsyinjika kwamkati kuchokera ku kuchepa kwa gawo lapansi. The poyambirira ndi zofunika PTFE a otsika pamwamba mphamvu.

Tepi ya PTFE yotentha kwambiri imakhala ngati chinthu chofunikira kwambiri popanga semiconductor, osati chogwiritsidwa ntchito ponseponse. Ntchito zazikuluzikulu: chitetezo chawafer-level (ma plasma etching masking, chitetezo cham'mbuyo cha CMP, CVD/PVD masking), njira zolongedza (kukhazikika kwa waya, chigoba cha soldering cha PCBs), ndi kukonza zida (anti-static roller kukulunga, cholemba pachipinda choyera). Zofunikira zoyera kwambiri: ma halogen otsika (amaletsa dzimbiri zomangira zomangira), ma siloxane otsika (<500 ppm, amalepheretsa kupanga tinthu tating'ono), ma ion achitsulo otsika (<1 ppm iliyonse), ISO Class 4 cleanroom slitting/package, 10⁶-10⁹ Ω TV surface resistivity, ndi kutsika kwa TV OC.

Tepi yotentha kwambiri ya PTFE yamankhwala imaphatikiza gawo laling'ono la PTFE logwirizana ndi zomatira za platinamu. Zofunika kwambiri: ISO 10993 yogwirizana (palibe cytotoxicity, sensitization, kapena irritation), imapirira kutsekereza mobwerezabwereza (steam/EO/gamma), 260°C kukana kutentha. Njira zodzitetezera: musapitirire 260 ° C (utsi wapoizoni wopitilira 300 ° C), kuyatsa kwa gamma kungayambitse kusokoneza, kutsimikizira njira zotsekera, ndikupempha zolemba zonse zotsatiridwa (malipoti a ISO 10993, MSDS, data yokalamba). Osati kuti agwiritse ntchito magazi achindunji kapena implantation pokhapokha atatsimikiziridwa mwachindunji.

PTFE tepi reusability zimadalira zinthu zinayi: zomatira chiphunzitso (mkulu crosslink kachulukidwe, otsika silikoni migration, microphase kapangidwe kwa repositionable tack), gawo lapansi anangula (pamwamba kutsegula + zoyambira kuteteza kutengerapo zomatira zonse), ❖ kuyanika kumbuyo (kumasula wosanjikiza kuteteza zomatira pa unwinding), ndi kagwiridwe koyenera (zoyera zomatira pamwamba, zomatira zolondola pamwamba, kupewa zomatira pamwamba). Zomatira zotsuka ndi madzi zimatha kuchira> 90% tack pambuyo poyeretsa.

Fiberglass nsalu matenthedwe shrinkage ndiye chifukwa chachikulu cha PTFE tepi dimensional kusakhazikika. Pa kutentha kwa PTFE sintering (360-400 ° C), kupsinjika kotsalira koluka kumatulutsidwa. Ngati sichiletsedwa, nsalu imachepa; Ngati atalephereka, kupsinjika kobisika kumatsekeredwa, kumapangitsa kuchepa pang'onopang'ono pakuchiritsa zomatira (150-200 ° C) ndikutentha komaliza. Yankho: gwiritsani ntchito magalasi a fiberglass asanayambe kutentha ndi <0.5% shrinkage pa 400 ° C, kuchotsa kupsinjika kotsalira musanayambe kupaka.

Tepi ya PTFE yotalikirana ndi kutentha imafunikira silikoni PSA yomwe imasunga zomatira kuchokera -70°C mpaka 260°C. Zinthu zazikuluzikulu zamapangidwe: kusanjikiza koyambira koyambira (kuteteza kutsetsereka), kusanjikizana kwa chilumba cha m'nyanja (MQ resin Islands + polysiloxane continuous phase), gradient crosslinking (wosanjikiza kwambiri wamkati wa kukana kukwawa, wosanjikiza wakunja wosanjikizana wocheperako), ndi zoziziritsa kutentha zokhazikika (cerium oxid resistance). Magawo a phenyl-modified siloxane amapondereza kutentha kwa crystallization, zomwe zimathandiza kusinthasintha pansipa -100 ° C.

Aokai PTFE adawonetsa mndandanda wake wonse wazinthu ku APFE Shanghai 2026 (Booth 6T602, Hall 6). Zogulitsa zomwe zili ndi fiberglass zolimbitsa thupi za PTFE, mafilimu oyera a PTFE, magiredi odana ndi malo amodzi, ndi malamba onyamula kutentha kwambiri - kuphimba chakudya, PV lamination, mabatire a lithiamu, zamagetsi, ndi ma CD. Chiwonetserochi chikudutsa pa June 26. Zogulitsa zonse zimathandizira ndondomeko yachizolowezi.

Chodulidwa kumapeto kwa nkhope ya PTFE tepi yotentha kwambiri imakhudza kwambiri zomatira ndikukweza m'mphepete panthawi yogwiritsira ntchito. Kung'ambika kosakwanira (masamba osawoneka bwino, ngodya zosayenera) kumapanga ulusi wa guluu, kufewetsa zomatira m'mphepete mwake, ndikuwonetsa magalasi a fiberglass - zomwe zimapangitsa kutulutsa, kulumikizana kofooka, ndikutukuka pakutentha kapena kupsinjika. Nkhope zosawoneka bwino (zopindikira, zotuluka) zimayambitsa kugawanikana kosagwirizana, kuyendetsa zomatira kukwawa panthawi yosungira. Nkhope yabwino yomalizira ndi yosalala, yonyezimira, komanso yopanda kuwonongeka - imagwira ntchito ngati chisindikizo chomwe chimatseka zomatira ndikuonetsetsa kuti pali mgwirizano wonse.

Pa PTFE tepi ❖ kuyanika, zosungunulira volatilization mlingo wa silikoni kuthamanga tcheru zomatira ndi yofunika ndondomeko chizindikiro. Kuthamanga kwambiri → kusenda pamwamba, kusayenda bwino, zibowo (zosungunulira zotsekeredwa), ndi ma craters (kuundana kapena kupangitsidwa ndi zoyipitsidwa). Kuchedwetsa kwambiri → kugwa, m'mbali zokhuthala, ndikunyowetsa pa PTFE yamphamvu yotsika. Njira yoyenera: kusinthasintha koyambirira kwapang'onopang'ono pakuwongolera ndi kuthawa kwa thovu, kenako kufulumizitsa kuyanika kuti mupange mawonekedwe. Gwiritsani ntchito zosungunulira zosakanizika (toluene/xylene + kuyanika mwachangu) ndi kutentha kwa uvuni wa gradient (otsika → sing’anga →pamwamba).
