Qeb: Polytetrafluoroethylene (PTFE) Cov khoom siv Teflon
Polytetrafluoroethylene (PTFE) yog ib qho hluavtaws fluoropolymer ntawm tetrafluoroethylene uas muaj ntau daim ntawv thov vim nws cov khoom tshwj xeeb. Nws tau pom los ntawm kev sib tsoo hauv xyoo 1938 los ntawm tus kws tshuaj hu ua Roy Plunkett thaum nws tab tom ua haujlwm tsim lub tub yees tshiab. PTFE feem ntau paub los ntawm lub npe Teflon, uas yog tus tswv ntawm lub tuam txhab tshuaj DuPont.
PTFE yog ib yam khoom uas tsis yog-reactive thiab thermally ruaj khov uas tiv taus cov tshuaj feem ntau, nrog rau cov kua qaub thiab cov hauv paus. Nws muaj cov coefficient tsawg heev ntawm kev sib txhuam, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv hauv cov ntawv thov uas tsis tshua muaj kev sib txhuam, xws li hauv bearings thiab seals. PTFE kuj yog ib qho zoo heev hluav taws xob insulator, ua rau nws muaj txiaj ntsig hauv kev siv hluav taws xob.
Ib qho ntawm feem nrov kev siv ntawm PTFE yog nyob rau hauv non-stick cookware. Cov khoom tsis-stick ntawm PTFE yog vim nws tsis tshua muaj zog nto, uas tiv thaiv cov zaub mov los ntawm lo rau saum npoo ntawm cookware. PTFE kuj tseem siv tau rau hauv lwm cov ntawv thov uas tsis yog cov khoom siv uas xav tau, xws li hauv cov txheej txheem kho mob thiab hauv kev tsim cov gaskets thiab seals.
PTFE kuj tseem siv rau hauv kev lag luam aerospace vim nws qhov kub thiab txias tsis kam thiab coefficient ntawm kev sib txhuam. Nws yog siv rau hauv kev tsim khoom ntawm cov khoom siv dav hlau, xws li cov ntsaws ruaj ruaj thiab cov kabmob. PTFE kuj tseem siv rau hauv kev tsim kho ntawm qhov chaw suits vim nws muaj peev xwm tiv taus qhov kub thiab txias thiab nws cov khoom tsis-stick.
Ntxiv nrog rau nws siv nyob rau hauv non-stick coatings thiab aerospace daim ntaub ntawv, PTFE kuj tseem siv rau hauv kev tsim khoom ntawm ntau yam khoom, xws li computer cables, automotive parts, thiab industrial coatings.
