Teflon yeeb nkab (PTFE) yog dab tsi?

1. Vim li cas nws thiaj li hu ua Teflon yeeb nkab (PTFE)? Lub npe Teflon yeeb nkab li cas?

Teflon yeeb nkab, tseem hu ua PTFE yeeb nkab, feem ntau hu ua "tus huab tais ntawm plastics", yog lub siab molecular polymerized nrog tetrafluoroethylene ua monomer. Dawb waxy, translucent, zoo heev tshav kub thiab txias tsis kam, tuaj yeem siv tau ntev ntawm -180 ~ 260ºC. Cov khoom no tsis muaj cov pigments lossis additives, yog acid-resistant, alkali-resistant thiab ntau yam organic solvents, thiab yuav luag insoluble nyob rau hauv tag nrho cov kuab tshuaj. Nyob rau tib lub sijhawm, PTFE muaj cov yam ntxwv ntawm qhov kub thiab txias tsis tshua muaj kev sib txhuam coefficient, yog li nws tuaj yeem siv rau lubrication, ua rau nws yog ib qho zoo tshaj plaws txheej yeeb nkab rau kev yooj yim ntxuav ntawm lub puab txheej ntawm cov kav dej.

①. Teflon du bore raj yog ua los ntawm kev kho tsis tau 100% PTFE resin thiab tsis muaj cov pigments lossis additives. Nws yog tsim rau siv nyob rau hauv aerospace thiab tsheb thauj mus los technology, electronics, Cheebtsam thiab insulators, tshuaj thiab kws tshuaj, khoom noj khoom haus, ib puag ncig kev tshawb fawb, huab cua sampling, kua hloov khoom siv thiab dej kho tshuab. Tag nrho cov kav dej muaj nyob rau hauv kev tiv thaiv zoo li qub (thawv) lossis cov xim xim.

②. Teflon corrugated yeeb nkab yog tsim los ntawm kev kho tsis tau 100% PTFE resin thiab tsis muaj cov pigments lossis additives. Nws muaj qhov yooj yooj yim thiab torsional tsis kam, muab kev ua tau zoo hauv cov ntawv thov uas yuav tsum tau nruj dua khoov radii, muaj peev xwm tuav tau ntau dua lossis sib tsoo ua haujlwm. Bellows muaj nyob rau hauv flares, flanges, cuffs los yog ib tug ua ke ntawm ntau yam optimized yeeb nkab daws. Tag nrho cov kav dej muaj nyob rau hauv anti-static (carbon) versions.

③. Cov yam ntxwv kub thiab corrosion kuj ntawm Teflon capillary raj tau dav siv nyob rau hauv corrosion-resistant industries, xws li tshuaj lom neeg kev lag luam, pickling, electroplating, tshuaj, anodizing thiab lwm yam lag luam. Capillary raj feem ntau muaj kev tiv thaiv zoo corrosion, zoo scaling kuj, zoo heev aging kuj, zoo tshav kub hloov kev kawm, me me kuj, me me, lub teeb yuag thiab compact qauv.
