Polytetrafluoroethylene (PTFE)tau tshawb pom los ntawm kws tshuaj Dr Roy J. Plunkett hauv DuPont's Jackson Laboratory hauv New Jersey xyoo 1938. Thaum nws sim ua CFC refrigerant tshiab, polytetrafluoroethylene polymerized nyob rau hauv lub siab-siab cia nkoj (cov hlau nyob rau hauv lub puab phab ntsa ntawm lub nkoj los ua tus catalyst rau cov tshuaj tiv thaiv polymerization).Lub tuam txhab DuPont tau txais nws daim ntawv pov thawj hauv xyoo 1941 thiab tau sau npe nws cov cim lag luam raws li lub npe "TEFLON" hauv xyoo 1944. Tom qab ntawd, DuPont pib ua lag luam hauv Teflon & reg;Ntxiv rau PTFE resin, peb tau tsim cov khoom lag luam, suav nrog Teflon;AF (amorphous fluoropolymer), Teflon;FEP (fluorinated ethylene propylene resin), Teflon;FFR (fluoropolymer foam resin), Teflon;NXT (fluoropolymer resin), Teflon;PFA (perfluoroalkoxy resin) thiab lwm yam.

Teflon conveyor siv

Cov khoom ntawm cov khoom no feem ntau hu ua "non-stick txheej";Nws yog ib yam khoom siv hluavtaws polymer uas siv fluorine los hloov tag nrho cov hydrogen atoms hauv polyethylene.Cov khoom no muaj cov yam ntxwv ntawm acid tsis kam, alkali tsis kam thiab ntau yam organic solvents, thiab nws yuav luag insoluble nyob rau hauv tag nrho cov kuab tshuaj.Nyob rau tib lub sijhawm, polytetrafluoroethylene muaj cov yam ntxwv ntawm qhov kub thiab txias tsis kam, thiab nws cov kev sib txhuam coefficient tsawg heev, yog li nws tuaj yeem siv los ua lubrication, thiab kuj dhau los ua cov txheej txheem zoo tshaj plaws yam tsis muaj roj yias thiab txheej hauv cov yeeb nkab dej.

Teflon siv tau rau hauv txoj siv conveyor: Teflon conveyor siv, Teflon conveyor siv, txias tawv conveyor siv, pipeline conveyor siv, Teflon ntaub, PTFE daim ntaub siv, ntaub pua plag siv, rooj lev ntaub, zaub mov conveyor siv, thiab lwm yam. kuj tseem siv rau ntawm daim kab xev: Teflon nplaum daim kab xev, Teflon iav fiber ntau nplaum daim kab xev, Teflon kub resistant daim kab xev, nws tus kheej nplaum daim kab xev, nws tus kheej nplaum vuam daim ntaub, thiab lwm yam.
