Chifukwa chiyani PTFE High-Temperature Fabric Flame-Resistant mu Open Fire? Kodi Njira Yake Yochepetsera Moto Wang'ono Ndi Yotani?

Jiangsu Aokai New Materials, wopanga nsalu zotentha kwambiri za PTFE, akufotokoza kuti:

PTFE mkulu-kutentha nsalu kwambiri lawi zosagwira pamoto, makamaka chifukwa cha maselo dongosolo ndi matenthedwe kuwola limagwirira ake pachimake zakuthupi — polytetrafluoroethylene (PTFE). Kuchedwa kwake kwa malawi sikudalira zowonjezera zoletsa moto monga zida wamba, koma zimachokera ku kusakhazikika kwachilengedwe kwamankhwala ndi machitidwe ake owonongeka.

Izi zitha kumveka kuchokera pamagulu atatu:

1. 'Zida' zolimba za Molecular: Mphamvu Zapamwamba za Bond ndi Chitetezo

Ma  bondi amphamvu a carbon-fluorine (C-F) : Mamolekyu a PTFE amakhala ndi msana wa kaboni wozunguliridwa ndi maatomu a fluorine. Chomangira cha C-F ndi chimodzi mwazinthu zodziwika bwino zamakhemikolo zodziwika bwino, zokhala ndi mphamvu zomangira pafupifupi 485 kJ/mol. Kutentha kwambiri (kutentha) kumafunika kuti kuswe, kupanga mzere woyamba wa chitetezo.

Kuteteza  mphamvu ya maatomu a fluorine : Ma atomu akuluakulu, osanjidwa bwino ndi fluorine amakhala odzaza kwambiri, amakhala ngati zida zankhondo zomwe zimatsekereza tcheni chamkati cha kaboni. Chotchinga ichi chimalepheretsa mankhwala ambiri (kuphatikiza okosijeni) kuti asalowe mu tcheni cha kaboni ndipo amalepheretsa mwamphamvu kuyatsa kofunikira kuti uyake.

2. Kuwola Kosayaka: Kuchotsa Polima M'malo Mowotcha

·  Unyolo scission pamaso makutidwe ndi okosijeni : Pa kutentha kwambiri, ndi ofooka mpweya mpweya (C-C) zomangira mkati PTFE yopuma pamaso C-F zomangira. Unyolo wa mamolekyulu umayamba kuwola mpweya usanalowemo.

·  Chogulitsa chachikulu ndi monoma : Ikasweka, PTFE makamaka imachita depolymerization , kutulutsa ma monomers a tetrafluoroethylene (C₂F₄) kuchokera kumapeto kwa unyolo. Zinthuzi zimaphikidwa m'malo moyaka mwachiwawa komwe kumatulutsa kutentha kwakukulu ndi mpweya woyaka.

·  Gasi-gawo chotchinga mphamvu : C₂F₄ mpweya wochokera ku depolymerization ndi wandiweyani kuposa mpweya ndipo umakhala pafupi ndi pamwamba, kupanga mpweya wosanjikiza kwakanthawi womwe umachepetsa kuchuluka kwa okosijeni ndikuwonjezera kuyaka.

3. Kuthandizira Udindo wa Glass Fiber Substrate

PTFE high-temperature nsalu ndi gulu lopangidwa ndi ❖ kuyanika PTFE pa galasi CHIKWANGWANI nsalu. Ulusi wagalasi womwewo ndi chinthu chosayaka moto. Monga mafupa opangidwa, zimatsimikizira kuti ngakhale pamwamba pa PTFE wosanjikiza watenthedwa kutentha kwakukulu, zinthuzo sizimasungunuka kapena kudontha ngati pulasitiki yoyera, kusunga umphumphu wapangidwe ndikuletsa kufalikira kwa moto.

Ziyenera kutsindika kuti PTFE ndi yoletsa moto , osati yoyaka moto. Ikatenthedwa pamwamba pa malo ake osungunuka (327 ° C) ndi mosalekeza, imawola ndikutulutsa utsi wapoizoni. Nthawi zambiri imapirira kutentha kwanthawi yayitali mpaka 260 ° C ndipo imakhala yosasunthika kwakanthawi pa 300-360 ° C.

Kuwola pamoto wotseguka : Mukawonekera mwachindunji pamoto wotseguka (kutali kwambiri ndi kutentha kwake kwa kutentha), PTFE wosanjikiza amawola, koma ndondomekoyi simapanga kutentha kokwanira kapena zoyaka kuti zipitirize kuyaka. Kuphatikizidwa ndi chithandizo cha fiber galasi, malawi sangathe kufalikira mosalekeza.

Mwachidule, PTFE pamwamba kutentha nsalu ndi lawi zosagwira chifukwa mfundo zake pachimake PTFE ndi molecularly kukana kuyaka .High-mphamvu mankhwala zomangira, njira kuwola wapadera, ndi osayaka magalasi CHIKWANGWANI mafupa a mafupa pamodzi kupanga chotchinga cholimba moto.

Zambiri pamwambapa zimaperekedwa ndi Jiangsu Aokai New Materials Technology Co., Ltd.

Kuti mumve zambiri, mawonekedwe ogwiritsira ntchito ndi mayankho makonda azinthu zathu zonse - kuphatikiza nsalu yotentha kwambiri ya PTFE, tepi ya PTFE yotentha kwambiri, lamba wa PTFE wotentha kwambiri, lamba wopanda waya wamakina omangira, nsalu imodzi ya PTFE, lamba wotenthetsera wotentha kwambiri ndi zinthu zina zosagwirizana ndi magalasi, chonde osagwira magalasi, lamba wosamva kutentha ndi zina.
