Teflon siab ua haujlwm tshwj xeeb txheej yogptfe uaRaws li lub hauv paus cob ntawm fluorine txheej, lus Askiv lub npe rau Teflon, vim hais tias ntawm kev hais lus, feem ntau kuj hu ua Teflon, Teflon, Teflon, Teflon thiab hais txog (tag nrho rau kev txhais lus ntawm Teflon).

Teflon muab faib ua PTFE, FEP, PFA, ETFE ob peb yam yooj yim: TEflon PTFE: PTFE (polytetrafluoron) non-stick txheej tuaj yeem siv tsis tu ncua ntawm 260 deG C, nrog kev siv siab tshaj plaws ntawm 290-300 DEG C, tsis tshua muaj kev sib txhuam coefficient, zoo hnav tsis kam thiab zoo heev tshuaj stability. Teflon FEP: FEP (fluorinated ethylene propylene copolymer) non-stick txheej melts thaum lub sij hawm ci los ua ib zaj duab xis tsis ntxeem tau, muaj tshuaj lom neeg ruaj khov, zoo heev uas tsis yog-stick zog, lub siab tshaj plaws kev khiav hauj lwm kub yog 200 ℃. Teflon PFA: PFA (perfluoroalkyl) non-stick coatings, zoo li FEP, yaj thaum ci los ua ib zaj duab xis ntxeem tau. Qhov zoo ntawm PFA yog siab dua kev siv kub ntawm 260 ℃, muaj zog toughness, tshwj xeeb tshaj yog haum rau kev siv cov kub kub nyob rau hauv lub premise ntawm anti-stick thiab tshuaj tiv thaiv nyob rau hauv lub teb ntawm kev siv. Teflon ETFE: ETFE yog copolymer ntawm ethylene thiab tetrafluoroethylene. Cov resin yog cov tawv fluoropolymer uas nyuaj tshaj plaws, tsim cov txheej txheem zoo heev nrog cov tshuaj lom neeg ua haujlwm tsis tu ncua ntawm 150 ° C.

Tom qab coated nrog Teflon, nws muaj cov yam ntxwv hauv qab no:

1, non-viscosity: yuav luag tag nrho cov khoom tsis sib txuas nrog teflon zaj duab xis. Cov nyias nyias kuj qhia tau zoo heev uas tsis yog-adhesion.

2, tshav kub tsis kam: Teflon zaj duab xis muaj cov cua kub zoo heev thiab tsis kub tsis kam. Lub sijhawm luv luv tuaj yeem tiv taus qhov kub siab txog 300 ℃, feem ntau ntawm 240 ℃ ~ 260 ℃ tuaj yeem siv tsis tu ncua, nrog cov cua sov tsis zoo, nws tuaj yeem ua haujlwm ntawm qhov kub thiab txias tsis muaj embrittlement, tsis yaj ntawm qhov kub thiab txias.

3, zawv zawg: Teflon zaj duab xis muaj qhov coefficient ntawm kev sib txhuam. Thaum lub load swb, kev sib txhuam coefficient hloov, tab sis tus nqi tsuas yog nyob nruab nrab ntawm 0.05 thiab 0.15.

4, noo noo tsis kam: teflon zaj duab xis nto tsis lo rau dej thiab roj, kev tswj ntau lawm tsis yooj yim rau lo rau cov tshuaj, xws li cov av me me, yooj yim so tuaj yeem raug tshem tawm. Lub sijhawm luv luv, txuag lub sijhawm thiab txhim kho kev ua haujlwm zoo.

5, hnav tsis kam: nyob rau hauv siab load, nrog zoo heev hnav kuj muaj nuj nqi. Nyob rau hauv ib qho kev thauj khoom, nws muaj ob qhov zoo ntawm kev hnav tsis kam thiab tsis-adhesion.

6. Corrosion kuj: Teflon yuav luag resistant rau tshuaj corrosion thiab tuaj yeem tiv thaiv qhov chaw ntawm txhua yam tshuaj yaig.
