Nsalu yotentha kwambiri ya PTFE (PTFE-yokutidwa ndi fiberglass) imakhala ndi kukana kwamphamvu kwa kutentha kwapakati pa -70°C mpaka 260°C. Imatha kulekerera kutentha kwapang'onopang'ono, mwachitsanzo, kuchoka pa -50 ° C mufiriji kupita ku makina osindikizira otentha a 260 ° C. Maphunziro apamwamba amapulumuka ngakhale kuzizira kwadzidzidzi kuchokera ku 260 ° C mpaka 10 ° C madzi. Komabe, kugwedeza zinthu kuchokera kutentha pamwamba pa 300 ° C (pafupi ndi PTFE's 327 ° C melting point) kungayambitse kusweka ndi delamination mwamsanga. Gawo la fiberglass limapereka bata laling'ono; Chophimba cha PTFE ndiye cholepheretsa.

PTFE mkulu-kutentha nsalu chimagwiritsidwa ntchito makampani mankhwala kwa ntchito zisanu ndi ziwiri zofunika: flange gaskets ndi linings chitoliro (amakana zidulo amphamvu / alkalis), riyakitala ndi linings thanki (kupewa dzimbiri zitsulo, kuyeretsa mosavuta), matumba fyuluta kwa dzimbiri chitoliro mpweya (mpaka 260 ° C), odana dzimbiri kukulitsa, zomangira zomangira, zomangira zomangira, zomangira zomangira, zomangira zomangira, zomangira zomangira zolumikizira. composite akamaumba, ndi magetsi / matenthedwe kutchinjiriza wraps. FDA ndi UL magiredi alipo.

Nsalu yotentha kwambiri ya PTFE (PTFE-yokutidwa ndi fiberglass) imapereka zabwino zinayi zazikulu monga anti-corrosion lining: inertness mankhwala (amatsutsa aqua regia, alkalis amphamvu, zosungunulira), kutentha kwakukulu (-70 ° C mpaka 260 ° C mosalekeza, 350 ° C pachimake), kukhazikika kwa dimensional (<0.5% kukhazikika), kuletsa kukhazikika kwapamwamba (<0.5%) Amagwiritsidwa ntchito m'mapaipi amankhwala, nsanja za desulfurization, matanki otola, ndi zida zazakudya/zamankhwala. Maphunziro a FDA alipo.

Nsalu yotentha kwambiri ya PTFE imapereka zabwino zisanu ndi chimodzi monga lamba wosindikizira wosindikizira: osagwira ndodo (mpaka wosindikizira ndi inki kumasulidwa mwaukhondo), 260°C kutentha kukana (kuyanika bwino), kukhazikika kwa dimensional (<0.5% elongation, kulembetsa kolondola), inertness yamankhwala (imakana phala la dzimbiri), kugunda kwamtundu, kutsika kwamtundu, kutsika kwamphamvu, kutsika kwamphamvu, kutsika kwamphamvu, kutsika kwamphamvu, kutsika kwamphamvu, kutsika kwamphamvu, kutsika kwamphamvu, kutsika kwamphamvu, kutsika kwamphamvu (kutentha kwapakati), antistatic). Zoyenera kusindikiza pazenera, kusindikiza kwa digito, ndi ntchito zosinthira kutentha.

Anti-static PTFE mkulu-kutentha nsalu Chili chosagwira ndodo, kutentha zosagwira (260°C), ndi katundu inert mankhwala muyezo PTFE ndi malo amodzi-dissipative ntchito. Ntchito zazikulu: kupanga zamagetsi (PCB lamination, component handling), PV module lamination (amateteza ESD kuwonongeka kwa maselo a dzuwa), kukonza chakudya ndi mankhwala (ESD-safe baking liners), zomera za mankhwala (anti-corrosion, anti-static ducting), ndi mafakitale a nsalu / kusindikiza. Kukaniza pamwamba nthawi zambiri 10⁶–10⁹ Ω.

Moyo wa ntchito ya nsalu ya PTFE yotentha kwambiri umasiyana kwambiri ndi kagwiritsidwe ntchito. Mankhwala odana ndi dzimbiri amatha kukhala zaka 3+ (4x motalika kuposa mphira). Ma tray ophikira chakudya miyezi yapitayi ndi kuwonongeka pang'ono. Malamba otengera mafakitale amavala kuchokera ku kukangana. PV lamination (150 ° C, EVA contact) ali ndi moyo wapakati. Ntchito zolimbana kwambiri (ma abrasive disc) amakhala ndi moyo waufupi. Mfundo zazikuluzikulu: kuwongolera kutentha (kukhala ≤260 ° C), pewani mikwingwirima yakuthwa, kuyeretsa nthawi zonse, ndikusintha munthawi yake mukakhala matuza kapena achikasu.

Nsalu ya PTFE yotentha kwambiri imakhala yokhazikika mpaka 300 ° C, koma pamoto imawola ndikutulutsa mpweya wapoizoni kwambiri: hydrogen fluoride (HF) (corrosive, pulmonary edema) ndi perfluoroisobutylene (PFIB) (yopanda mtundu, yopanda fungo, ~ 10x poizoni kwambiri kuposa phosgene, antido). Komanso carbon monoxide, zotsalira za PFOA, ndi kufufuza ma dioxin. Masks wamba wamba sagwira ntchito; gwiritsani ntchito zida zopumira zokha (SCBA). Zizindikiro zitha kuchedwa.

Nsalu ya PTFE yotentha kwambiri (PTFE-yokutidwa ndi fiberglass) ndi yabwino kutenthetsa ma microwave chifukwa imatumiza ma microwave popanda kuyamwa mphamvu, imalimbana ndi 260 ° C, ndipo imakhala ndi malo osasunthika. Mapulogalamuwa akuphatikiza ma microwave ophikira, malamba owumitsira makina owumitsira makina, zomangira zopangira mafuta kuti zigayidwe, ndi matumba a popcorn a microwave. Magulu a FDA omwe amapezeka kuti agwirizane ndi chakudya.

Nsalu ya PTFE yotentha kwambiri (PTFE-yokutidwa ndi fiberglass) imakhala yosasunthika bwino chifukwa gawo lapansi la fiberglass ndilokhazikika. Nsalu zoonda (0.08mm) zimapulumuka mazana mpaka masauzande; magiredi olemera (> 0.25mm) amasweka pambuyo pambiri. Zoluka za Satin zimaposa zoluka zamba. Kuti mupirire mobwerezabwereza, ganizirani filimu yolimba ya PTFE kapena nsalu yochokera ku aramid m'malo mwake.

Nsalu zotentha kwambiri za PTFE (PTFE-zokutidwa ndi fiberglass) zimagwiritsidwa ntchito kwambiri posindikiza nsalu ndi utoto wa malamba osindikizira kutentha (180-230°C), zovundikira patebulo losindikizira, zowumitsa malamba, malamba ophatikiza makina, ndi zokutira zogudubuza. Malo ake osamata amalepheretsa zotsalira za inki / zomatira, kuchepetsa nthawi yoyeretsa komanso kukonza bwino nsalu. Malamba opanda malire amathandizira kupanga mosalekeza.
