Kapangidwe ka Mamolekyulu a PTFE ndi Katundu Wake Wabwino Kwambiri

Monga katswiri wopanga nsalu za PTFE zotentha kwambiri, Jiangsu Aokai New Materials imakupatsirani luntha laukadaulo. Chigawo chapakati cha PTFE mkulu-kutentha nsalu ndi Polytetrafluoroethylene (PTFE), ndi kapangidwe maselo a (mathbf{-(CF_2-CF_2)_n-}). Unyolo waukulu wa kaboni umakutidwa ndi maatomu a fluorine. Zinthu zitatu zapamwambazi zimagwirizana ndi mawonekedwe a mamolekyu a PTFE pamagawo osiyanasiyana:

1. Katundu Wabwino Kwambiri Wopanda ndodo

Zochokera ku mphamvu zotsika kwambiri zapamtunda, zomwe zimatsimikiziridwa ndi kukulungidwa kwakunja kwa maatomu a fluorine  ndi mamolekyulu a non-polarity..

Kuteteza kwakukulu  kwa maatomu a fluorine: Fluorine imakhala ndi mphamvu yamphamvu kwambiri yamagetsi komanso ma radius akulu a van der Waals. Mowirikiza komanso mowirikiza mozungulira mozungulira mbali yakunja ya tcheni cha kaboni, maatomu a fluorine amapanga chigoba chotchinga chotchinga ndikupanga malo osalala bwino osalala.

·  Mphamvu yofooka ya ma intermolecular: Ngakhale kuti mgwirizano wa CF ndi wa polar kwambiri, kulinganiza kokwanira bwino kumapangitsa kuti ma molekyulu onse asakhale polar. Zofooka zokha zobalalika zimakhalapo pakati pa mamolekyu, zomwe zimapangitsa kuti pakhale mphamvu yotsika kwambiri (pafupifupi 18 mN/m). Pafupifupi palibe zinthu zomwe zingafalikire kapena kumamatira pamwamba pa PTFE.

2. Acid Yamphamvu & Alkali Corrosion Resistance

Zochokera ku inertness yamphamvu kwambiri yamankhwala, yotsimikiziridwa ndi mphamvu yayikulu ya CF bond  ndi steric shielding effect..

·  Ma CF bond amphamvu kwambiri: Bond ya CF imakhala ndi mphamvu yopitilira muyeso (pafupifupi 485 kJ/mol), yokhazikika kwambiri kuposa ma CH ndi ma CC bond, ndipo ndi yovuta kwambiri kuthyoka.

Kuteteza kwathunthu  : Chipolopolo cholimba cha atomu ya fluorine chimatsekereza mafupa am'maketani a kaboni, kuletsa ma ayoni owononga kuti asagwirizane ndi tcheni cha carbon chomwe chili pachiwopsezo. Imazindikira chitetezo chapawiri chakuthupi ndi chamankhwala.

3. Superior Electrical Insulation

Zochokera ku polarizability yotsika kwambiri ndi ziro zaulere, zotsimikiziridwa ndi ma cell symmetry  ndi mphamvu yomangirira ma elekitironi.

·  Kapangidwe kake kosagwirizana ndi polar: Ngakhale kuti ma CF bond amtundu wamtundu wa polarity amasiyanasiyana, ma symmetrical makonzedwe a maatomu a fluorine mbali zonse za kaboni umapangitsa kuti pakhale mphindi pafupifupi ziro, zomwe zimapangitsa kuti PTFE ikhale yopanda polar.

Ma  elekitironi omangidwa mwamphamvu: Mphamvu yamagetsi yamphamvu ya maatomu a fluorine imakoka mitambo ya elekitironi molimba ku maatomu a fluorine. Ma electron mkati mwa mamolekyu sangasunthe kapena kumasuka pansi pa malo amagetsi akunja, ndi kusowa kwa zonyamulira za conductive. Chifukwa chake, PTFE imadzitamandira kutayika kotsika kwambiri kwa dielectric komanso mphamvu yakuwonongeka kwakukulu.

Chidule

Kukulungidwa kwathunthu kwa unyolo wa kaboni ndi maatomu a fluorine, zomangira zazifupi zamphamvu za CF, komanso ma symmetrical non-polar molecular makonzedwe amathandizira pakupanga kwapadera kwa PTFE: kusamata, kukana dzimbiri komanso kutchinjiriza kwamagetsi.

Zomwe zili pamwambapa zimaperekedwa ndi Jiangsu Aokai New Material Technology Co., Ltd.

Ngati mukufuna zambiri zokhudzana ndi magawo atsatanetsatane, zochitika zamagwiritsidwe ntchito ndi mayankho makonda pazogulitsa zathu zonse, kuphatikiza nsalu za PTFE zotentha kwambiri, matepi a PTFE otenthetsera kwambiri, malamba a PTFE apamwamba, malamba opanda msoko, nsalu zamtundu umodzi wa PTFE zokutira, nsalu zotchinga ndi magalasi apamwamba kwambiri nsalu, chonde omasuka kulankhula nafe:

·  Nambala yafoni yautumiki: Mr. Guo: +86 18944819998

·  Bambo Liu: +86 13705266308

Nthawi zonse timatsatira chiphunzitso cha ukatswiri ndi umphumphu, ndipo ndi mtima wonse timakupatsirani mayankho okhazikika ndi ntchito yoganizira pambuyo pogulitsa.
