Ulendo wa Teflon kuchokera ku ngozi ya labotale kupita kuzinthu zopezeka m'mapulogalamu ambiri umatsimikizira kufunika kwake. Chikhalidwe chake chopanda ndodo, kuphatikizapo mphamvu yake yolimbana ndi kutentha kwakukulu ndi mankhwala owononga, zimapangitsa kukhala chinthu chosankhidwa m'madera ambiri. Kaya ndi m’khichini, m’misewu, m’mafakitale, kapena m’zipatala, yankho la ‘chomwe Teflon limagwiritsiridwa ntchito’ likuwonekera m’kugwiritsiridwa ntchito kwake kofala ndi kosiyanasiyana.
Chiyambi cha Teflon (PTFE)
Teflon, dzina lachidziwitso lofanana ndi mnzake wamankhwala, polytetrafluoroethylene (PTFE), yasintha mabizinesi ambiri kuyambira pomwe idapezeka mwangozi mu 1938 ndi Roy J. Plunkett. Kutulukira koopsa kumeneku kunachitika ku United States pamene Plunkett ankagwira ntchito yokonza mafiriji. Anapeza kuti chitsanzo chozizira, choponderezedwa cha tetrafluoroethylene chopangidwa kukhala choyera, cholimba, chosonyeza kubadwa kwa Teflon.
Chomwe chimasiyanitsa Teflon ndi mawonekedwe ake odabwitsa. Amadziwika bwino chifukwa chosagwira ndodo, chinthu chomwe chapanga dzina lanyumba mu kitchenware. Chophika chophimbidwa ndi Teflon chimathandizira kuphika ndi kuyeretsa, zomwe zikuyimira kupita patsogolo kwakukulu pakukonza zakudya komanso zaluso zophikira. Ntchito za Teflon, komabe, zimapitilira kukhitchini.
Pankhani ya kukana kutentha, Teflon imadziwika kuti imatha kupirira kutentha kwambiri popanda kutaya kukhulupirika kwake. Khalidweli limapangitsa kuti likhale lofunika kwambiri popanga zinthu zomwe zimakhudza kutentha kwambiri, makamaka m'makampani opanga mankhwala ndi magalimoto. Mphamvu zake zapamwamba komanso zosagwira dzimbiri ndichifukwa chake zokutira za Teflon ndizofala muzogwiritsa ntchito zosiyanasiyana kuphatikiza zakuthambo, komwe kudalirika ndi kulimba ndikofunikira.
Chinthu chinanso chofunika kwambiri cha Teflon ndi kusakhazikika kwa mankhwala. Imawonetsa kukana kwapadera kwa mankhwala owononga, ndikupangitsa kuti ikhale yofunika kwambiri pazida zopangira mankhwala. Kukaniza uku kumatsimikizira kuti Teflon imatha kuthana ndi zinthu zambiri popanda kuwonongeka, kutsimikizira moyo wautali komanso chitetezo.
Kugwiritsa ntchito kwa Teflon pazachipatala sikungapitirire. Kapangidwe kake ka mankhwala kumapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pachipatala, komwe kuyanjana kwake ndi chikhalidwe cha inert ndikofunikira. Kuchokera pazida zopangira opaleshoni kupita ku ma catheter, gawo la Teflon pakupititsa patsogolo luso lachipatala ndi lofunikira.
Kuchuluka kwa Teflon kumapitilira kukhitchini, chifukwa kumapeza zofunikira pazambiri zamafakitale. Zinthu zapaderazi zasintha momwe zinthu zimapangidwira, chifukwa cha zinthu zake zodabwitsa zomwe zimakwaniritsa zofunikira zamagulu osiyanasiyana.
Makina ndi Zida Zagalimoto
Pamakina ndi uinjiniya wamagalimoto, Teflon imatenga malo oyambira, makamaka pamayendedwe ndi magiya. Zofunikira izi zimapindula kwambiri ndi zokutira za Teflon, zomwe zimachepetsa kwambiri kukangana ndi kuvala. Kusanthula koyendetsedwa ndi data kukuwonetsa kuti ma bere ndi magiya okutidwa ndi Teflon amachepera mpaka 50% kung'ambika poyerekeza ndi omwe sanakutidwe. Izi zikutanthawuza kuwonjezeka kwa moyo wautali komanso kugwira ntchito bwino pamakina ndi magalimoto.
Magetsi Insulation ndi Aerospace Components
M'mafakitale apamlengalenga ndi zamagetsi, mawonekedwe apadera a Teflon amalumikizidwa ndi mphamvu zawo zotsekereza. Kafukufuku wambiri amatsimikizira mphamvu ya dielectric yapadera ya Teflon, ndikupangitsa kukhala chisankho chokondedwa pamawaya ndi zingwe. Deta imatsimikizira kuti kusungunula kwa Teflon kumateteza bwino makina amagetsi, kuchepetsa chiopsezo cha kuwonongeka kwa magetsi ndikuwonetsetsa kuti magetsi sangasokonezeke. Momwemonso, m'mlengalenga, komwe kumakhala koopsa, kukana kwa Teflon kutentha kwambiri ndi mankhwala owononga ndikofunikira. Zambiri kuchokera pakuyezetsa kokwanira zimatsimikizira kuti zida za Teflon zimasunga umphumphu, ngakhale m'malo ovuta kwambiri.
Kukhalitsa ndi Kukaniza
Kukhalitsa kwa Teflon ndi kukana kutentha kwambiri ndi zinthu zowononga ndizo maziko a luso lake la mafakitale. Umboni wochirikizidwa ndi deta umasonyeza kukhoza kwa Teflon kupirira kutentha kwapakati pa -250 madigiri Celsius mpaka kupitirira 260 digiri Celsius (-418 mpaka 500 madigiri Fahrenheit). Kusiyanasiyana kodabwitsaku kumapangitsa kuti ikhale yothandiza pamagwiritsidwe omwe amakumana ndi ma cryogenic komanso kutentha kwambiri.
Kuphatikiza apo, kukana kwa Teflon kumitundu yambiri yamankhwala, kuphatikiza ma acid ndi maziko, kumalembedwa bwino. Imakhalabe yosasunthika ngakhale ikukumana ndi mankhwala owononga, kusunga umphumphu wa zigawo zofunika kwambiri ndi zipangizo.
Kugwiritsiridwa ntchito kwa Teflon m'mafakitale ndi umboni wa ubwino wake wothandizidwa ndi deta. Kaya mumakina, zida zamagalimoto, zotchingira magetsi, kapena zida zammlengalenga, magwiridwe antchito a Teflon amapitilira zomwe amayembekezera. Kukhalitsa kwake ndi kukana kutentha kwakukulu ndi zinthu zowonongeka kumapangitsa kukhala chinthu chamtengo wapatali pa ntchito za mafakitale, kumene kudalirika ndi moyo wautali ndizofunikira kwambiri.
Dinani apa kuti mudziwe zambiri za 'Mapulogalamu a Teflon'
Teflon mu Consumer Electronics ndi Zinthu Zapakhomo
Chikoka cha Teflon chimafikiranso pazamagetsi ogula ndi zinthu zapakhomo za tsiku ndi tsiku, mothandizidwa ndi zomwe zimagwira ntchito bwino komanso kukula kwa msika.
Kupititsa patsogolo Kukhalitsa mu Zamagetsi
M'dziko lopikisana kwambiri lamagetsi ogula, zokutira za Teflon zimagwira ntchito yofunika kwambiri pakukulitsa kulimba kwazinthu. Kusanthula kwa data kuchokera kwa opanga otsogola kukuwonetsa kuti zida zamagetsi zokhala ndi zida zophimbidwa ndi Teflon zimawonetsa kulephera kwakukulu chifukwa cha chilengedwe. Zovalazi zimakhala ngati chotchinga chinyezi, fumbi, ndi zonyansa zina, zomwe zimachepetsa mwayi wowonongeka. Kuwongolera kowoneka bwino kumeneku pakudalirika kwa zida kwathandizira kuti Teflon ichuluke pamsika wamagetsi ogula zinthu, womwe akuti umakhala wokwera mabiliyoni a madola pachaka.
Kuphatikiza apo, kukana kwa Teflon kutentha kwambiri kumatsimikizira kuti zida zamagetsi zimakhalabe zokhazikika ngakhale zitagwiritsidwa ntchito nthawi yayitali kutentha kwambiri. Ubwino wothandizidwa ndi datawu ndi wofunikira kwambiri pama laputopu, mafoni am'manja, ndi zida zina zomwe zimatulutsa kutentha pakamagwira ntchito.
Zinthu zatsiku ndi tsiku zimasinthidwanso
Kusinthasintha kwa Teflon kumawonekera muzinthu zambiri za tsiku ndi tsiku, kuyambira nsalu ndi makapeti mpaka zokutira zovala zamaso. Deta imalankhula zambiri za momwe Teflon imakhudzira magwiridwe antchito azinthuzi komanso gawo la msika.
