Dziwani zambiri zakugwiritsa ntchito kwa Teflon, kuchokera ku zophika zosamata mpaka kumakina akumafakitale. Phunzirani zomwe Teflon imagwiritsidwa ntchito komanso kusinthasintha kwake m'magawo onse.

Polytetrafluoroethylene inapezeka mu 1938. Poyamba inapezedwa ndi katswiri wa zamankhwala wa ku America Roy J. Plunkett (1910-1994) pamene amayesa kupanga mufiriji watsopano wa carbon ndi fluorine.

Pakati pa poto wokutidwa ndi Teflon, kunong'onezana kumatuluka: Kodi Teflon ndi yotetezeka pakatentha kwambiri komanso nkhawa za PFOA? Tiyeni tiwulule chowonadi kumbuyo kwa zinthu za Teflon.

ETFE ikusintha momwe timaganizira za kapangidwe ka wowonjezera kutentha. Tiwona zodabwitsa za zomangamanga za ETFE ndi momwe filimu yodabwitsayi ya ETFE ikufotokozeranso tsogolo la zomangamanga zokhazikika.

Dziwani zamatsenga a zophika zopanda zomata! Phunzirani za PTFE-zokutidwa ndi mapani a ceramic. Kodi zokutira pa poto yopanda ndodo ndi chiyani? Zindikirani sayansi yomwe idayambitsa kusintha kosasunthika.

'Kuti mudziwe ngati miphika ndi mapoto anu ali ndi Teflon, yang'anireni ngati zokutira zopanda ndodo. Komanso, yang'ananinso zomwe zapakidwa za logo ya Teflon, kuwonetsetsa kuti muli ndi zophikira zomwe zili ndi zinthu zodziwika bwino zosagwira.'

Pini yopanda ndodo nthawi zambiri imapangidwa kuchokera kuzinthu zoyambira monga aluminiyamu kapena chitsulo chosapanga dzimbiri. Siginecha yake ndi zokutira, zomwe zimapangidwa ndi polytetrafluoroethylene (PTFE) kapena nthawi zina ceramic, zomwe zimatsimikizira kuti chakudya sichimamatira pamwamba, kupanga kuphika ndi kuyeretsa kosavuta.

Munayamba mwadzifunsapo kuti, 'Kodi kutsekemera kusungunula teflon tepi?' Lowani mu sayansi ndi mphamvu ya teflon tepi mukakumana ndi kutentha kwa soldering. Pezani zidziwitso zamtengo wapatali kuti muwonetsetse kuti pali kulumikizana kotetezeka, kopanda kutayikira muzochita zanu zonse zapaipi.'

Lowani mozama mumkangano wa Teflon vs Nylon. Kuchokera ku mphamvu zamakina, kukana kuvala, kuyamwa kwa chinyezi, nkhaniyi ikuphwanya makhalidwe awo ndi ntchito zawo. Dzikonzekeretseni ndi chidziwitso kuti mudziwe zoyenera kuchita bwino pantchito yanu.

Dziwani kuchedwa kwamoto kwa PVC ndi Teflon. Phunzirani za katundu wawo, kukana kutentha, ndi zina zambiri m'nkhani yathu yowunikira. Dzilowetseni lero!
