Kodi PTFE ndi Teflon ndi chinthu chimodzi?

Ili ndiye funso lalikulu, ndipo yankho lake ndi losavuta: inde, PTFE ndi Teflon ndi zinthu zomwezo. Komabe, "zinthu zomwezo" ndi "mawu omwewo" sizitanthauza chinthu chomwecho pankhani yogula zinthu—kumvetsa kusiyana kumeneku kumapangitsa mafunso onse otsatira kukhala osavuta.

PTFE = Polytetrafluoroethylene = Dzina la mankhwala

PTFE imayimira Polytetrafluoroethylene, yomwe imadziwika kwambiri m'Chitchaina kuti "polytetrafluoroethylene." Ili ndi dzina la mankhwala lomwe limatanthauza polima yopangidwa kuchokera ku tetrafluoroethylene monomers. Mosasamala kanthu za komwe zipangizo zopangira zimachokera, zinthu zonse za polytetrafluoroethylene zopangidwa ndi kampani iliyonse zimalembedwa mofanana kuti PTFE—mawu ofanana ndi a makampani omwe si a wopanga aliyense.

Teflon® = Chizindikiro cholembetsedwa cha DuPont

Teflon® ndi chizindikiro cholembetsedwa cha Chemours (chomwe chinachokera ku DuPont mu 2015). Mu 1938, wasayansi wa ku DuPont, Roy Plunkett, adapeza mwangozi PTFE, ndipo kampaniyo inayamba kuigulitsa pansi pa chizindikiro cha Teflon® mu 1945. Kunena zoona, Teflon® imatanthauza "PTFE yopangidwa ndi DuPont/Chemours" —monga momwe Kleenex® imayimira mtundu winawake wa matawulo a mapepala.

Komabe, zenizeni n'zovuta kwambiri kuposa momwe matanthauzo amanenera. Mu makampani, "Teflon" yakhala yofanana ndi PTFE, ndipo ogulitsa ambiri amagwiritsa ntchito mawuwa pofotokoza zinthu zawo popanda chilolezo—chizolowezi chomwe chimapezeka kwambiri m'magawo opanga zinthu ku China: makasitomala akamapempha "machubu a Teflon," ogulitsa padziko lonse lapansi amazindikira izi ngati akunena za machubu a PTFE. Ku Besteflon, nthawi zambiri timakumana ndi mafunso otere; titatsimikizira zomwe zili muzinthuzo, nthawi zonse timatchula PTFE m'malemba ovomerezeka kuti tipewe kusamveka bwino.

 

Chifukwa chiyani "Teflon" sikutanthauza PTFE kwenikweni?

Ngati Teflon ikanakhala dzina la malonda la PTFE, nkhaniyi ikanakhala yosavuta. Komabe, kwenikweni, Chemours imagulitsa fluoropolymer zoposa imodzi pansi pa dzina la Teflon®. Izi ndiye chifukwa chachikulu cha chisokonezo chogula ndipo zikuwonetsa kufunikira kolondola kwambiri polemba zofunikira.

Pakadali pano Chemours imagulitsa zinthu zotsatirazi pansi pa dzina la Teflon®:

 

 

Izi zikutanthauza kuti pamene wogulitsa akunena kuti "timapereka machubu a Teflon," akhoza kukhala akunena za machubu a PTFE, machubu a PFA, kapena machubu a FEP. Zipangizo zitatuzi zimasiyana kwambiri pa kutentha kwawo kwakukulu, zofunikira pakukonza, ndi mitengo; cholakwika cha zilembo chimodzi chingayambitse magwiridwe antchito osiyana kwambiri akaperekedwa.

Malangizo: Nthawi zonse gwiritsani ntchito mayina a mankhwala (PTFE/PFA/FEP) mu maoda ogulira, ma specifications, ndi ma contract; pewani kugwiritsa ntchito "Teflon." Izi si kungoseka chabe koma njira yosavuta yopewera mikangano yotumizira. Dziwani kuti Besteflon yonseZogulitsa zamachubu a PTFEAmalembedwa mayina a mankhwala m'malo mwa "Teflon" - chifukwa kulondola kumaposa kuphweka.

 

Ndani mwini wa chizindikiro cha Teflon®?

Ngakhale kuti umwini wa chizindikiro cha malonda ungaoneke ngati nkhani yalamulo, umatsimikiza mwachindunji ngati ogulitsa anu angagwiritse ntchito mwalamulo mawu oti "Teflon" ndi zinthu zomwe zimagwiritsidwa ntchito mu "chubu cha Teflon" chomwe mumagula.

Mbiri ya Zizindikiro Zamalonda

•1938,Wasayansi wa ku DuPont, Roy Plunkett, adapeza PTFE.

•1945:DuPont inalembetsa chizindikiro cha Teflon® ndipo inayamba kugulitsidwa.

•2015:DuPont inayamba bizinesi yake ya mankhwala opangira zinthu zosiyanasiyana mu kampani yodziyimira payokha ya Chemours, ndipo chizindikiro cha Teflon® chinaperekedwa kwa Chemours.

•SkutaliChemours ili ndi chizindikiro cha Teflon® ndipo imapereka ufulu wopereka zilolezo kwa ogula utomoni wa PTFE padziko lonse lapansi.

Kodi izi zikutanthauza chiyani pankhani yogula zinthu?

Kukhala ndi chizindikiro cha malonda mwalamulo kuli ndi zotsatira ziwiri zothandiza pa kugula:

1. Wogulitsa wanu sangakhale ndi chilolezo cholemba chizindikiro cha Teflon® pa chinthucho.Ngati wopanga mapaipi agwiritsa ntchito chizindikiro cha Teflon® pa zilembo za malonda kapena mawebusayiti popanda kupeza chilolezo cha mtundu kuchokera ku Chemours, izi zikutanthauza kuphwanya malamulo a chizindikiro cha malonda. Izi sizikhudza mtundu wa zinthuzo—mafakitale ambiri aku China amagwiritsa ntchito utomoni wa PTFE wopangidwa mdziko muno (monga Dongyue, Haohua, ndi zina zotero), womwe umakwaniritsa miyezo yonse ya magwiridwe antchito—koma simungathe kulemba chizindikiro cha Teflon® pa chinthu chomaliza.

2. "Chubu cha Teflon" sichingagwiritsidwe ntchito ngati maziko olandirira.Lamulo logulira liyenera kufotokoza "chubu cha Teflon"; wogulitsa akhoza kupereka mtundu uliwonse wa chitoliro cha fluoropolymer. Kungotchula "chubu cha PTFE" kapena "chubu cha PFA" kungakhale muyezo wovomerezeka waukadaulo ngati pakhala mikangano.

 

Kodi makhalidwe a PTFE ochokera ku magwero osiyanasiyana ndi ofanana kwathunthu?
