Kodi Mfundo Yogwira Ntchito ya Teflon's Non-Stick Surface ndi chiyani?

Jiangsu Aokai New Materials, wopanga nsalu zotentha kwambiri za Teflon, akufotokoza za sayansi kumbuyo kwake.Katundu wabwino kwambiri wopanda ndodo wa Teflon (dzina lamankhwala: Polytetrafluoroethylene, PTFE) makamaka amachokera ku mfundo ziwiri zazikuluzikulu: mphamvu yotsika pamwamba  komanso mawonekedwe ake apadera a maselo..

1. Mphamvu Zotsika Kwambiri Pamwamba

Iyi ndiye mfundo yofunika kwambiri ya physicochemical of non-stick performance. Mphamvu zapamwamba zimatsimikizira kuti malo olimba amatha kunyowetsedwa mosavuta ndi zakumwa.

Teflon ili ndi mphamvu yotsika kwambiri padziko lapansi (pafupifupi 18.5 mN/m ), yotsika kwambiri kuposa zomatira wamba, mafuta, kapena madzi (kuthamanga kwamadzi pafupifupi 72 mN/m).

Malinga ndi chiphunzitso chonyowa , madzi amatha kufalikira pamtunda wokhazikika ngati kugwedezeka kwake kumakhala kochepa kuposa mphamvu yamphamvu. M'malo mwake, amagwera m'malovu (monga madzi patsamba la lotus) okhala ndi ngodya yolumikizana kwambiri (nthawi zambiri> 90 °, ngakhale pafupi ndi 120 °).

Zotsatira : Malo enieni olumikizirana pakati pa zomatira ndi Teflon ndi ochepa kwambiri, kotero palibe kulumikiza kwamphamvu kwamakina kapena kulumikizana kwamankhwala komwe kungachitike. Chifukwa chake zowononga zimachoka kapena zitha kuchotsedwa mosavuta.

2. Mabondi Amphamvu a C-F ndi Maonekedwe Osakhala a Polar Molecular

Maselo a Teflon amapangidwa ndi msana wa kaboni wozunguliridwa ndi maatomu a fluorine.

·  Mphamvu yolimba kwambiri : Chomangira cha carbon-fluorine (C–F) ndi chimodzi mwazinthu zolimba kwambiri mu organic chemistry. Izi zimapangitsa Teflon kukhala wokhazikika pamakina komanso pafupifupi kulowetsa pafupifupi zinthu zonse (kupatula zitsulo za alkali zosungunuka ndi ma fluorinating agents ochepa). Sizimapanga zomangira zamagulu (zogwirizana kapena zolimba za haidrojeni) ndi zida zomata.

·  Low polarity : Ngakhale fluorine imakhala ndi electronegative kwambiri, makonzedwe ake ofananira pamodzi ndi unyolo wa maselo amathetsa nthawi yonse ya dipole. Teflon mwamphamvu sanali polar, hydrophobic, ndi oleophobic.Water (polar) ndi mafuta (osakhala polar koma mkulu pamwamba tension) sangathe kupanga kwambiri intermolecular mphamvu (ofooka van der Waals mphamvu) ndi Teflon.

3. Kugwirizana Pakati pa Low Friction Coefficient ndi Non-Stick Performance

Ngakhale kugunda kocheperako kumatanthawuza kutsetsereka kolimba-kolimba, kumayenderana ndi khalidwe lopanda ndodo.

Teflon ili ndi imodzi mwazinthu zotsika kwambiri zogundana pakati pa zida zonse zolimba (zozungulira 0.04).

Zinthu zomata zikayesa kumamatira, kukangana kochepa kwambiri kumalepheretsa 'kugwira' pamwamba. Ngakhale kumamatira kofooka, mphamvu yakunja kapena mphamvu yokoka pang'ono imapangitsa kuti zinthuzo zisunthike ndikutuluka mosavuta.

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

Pazigawo zatsatanetsatane, mawonekedwe ogwiritsira ntchito ndi mayankho makonda azinthu zathu zonse, kuphatikiza nsalu ya Teflon yotentha kwambiri, tepi ya Teflon yotentha kwambiri, malamba amtundu wa Teflon, malamba opanda msoko amakina omangira, nsalu ya PTFE ya mbali imodzi, lamba wotentha kwambiri, wosamva magalasi, chokondera. tiuzeni kudzera:

Timatsatira nzeru zaukadaulo komanso zowona mtima zautumiki, ndipo tadzipereka kukupatsirani mayankho okhazikika komanso ntchito yachidwi!
