Ib tug lig fluorinated polymer uas yog semi-crystalline, semi-opaque thiab dawb.Nws muaj cov tshuaj tiv thaiv zoo heev uas tsis cuam tshuam los ntawm yuav luag txhua yam tshuaj thiab tseem muaj cov pa oxygen siab heev (piv txwv li yog qhov tsis muaj nplaim taws).Nws muaj qhov coefficient tsawg heev ntawm kev sib txhuam thiab ruaj khov rau qhov kub thiab txias.Nws yog mos, yooj yim deformed, yooj yim heev rau nkag thiab tsis tshua muaj zog nrog cov hluav taws xob tsis zoo.Nws tseem kim heev thiab tsis tuaj yeem yaj-ua tiav (txawm hais tias nyob rau hauv txoj kev xav nws melts ntawm 327C, lub yaj viscosity ntawm cov qib ib txwm yog infinite) thiab yog li yog tsim los ntawm cov hmoov sintering txoj kev.
Cov ntawv thov muaj xws li bearings, ntsaws ruaj ruaj, O-rings, kub kub hluav taws xob rwb thaiv tsev, tsis yog-stick coatings thiab linings rau cov hlab ntsha thiab lwm yam, thiab lwm yam.
Cov opaque dawbPTFE Spheremuaj cov av tiav thiab tus qauv kam rau ua.Polypropylene (PP) yog ib lub hnab yas uas muaj zog, lub teeb yuag nrog ib qho nyuaj, du nto uas haum rau kev siv qhov twg cov kab mob tuaj yeem yog qhov tseem ceeb.Feem ntau muaj zog dua, nruj dua, thiab tiv taus qhov kub thiab txias dua li polyethylene, polypropylene kuj muaj qhov ua haujlwm zoo rau cov tshuaj thiab cov kuab tshuaj.
Yas yog hais txog ib pawg ntawm cov khoom siv hluavtaws lossis semi-synthetic uas tau tsim los ua kom tiav cov khoom tshwj xeeb.Cov yam ntxwv tseem ceeb tshaj plaws ntawm cov yas yog nws qhov hnyav, machinability, corrosion kuj, thiab feem ntau zoo thermal thiab hluav taws xob insulating zog.Qee qib yas kuj muaj qhov pom kev pom zoo ib yam li iav, tsis tshua muaj kev sib txhuam los yog nws tus kheej-lubricating qhov chaw, thiab muaj kev cuam tshuam tshwj xeeb.Nyob ntawm lawv cov khoom, qee cov qib yas tuaj yeem siv los ua lwm hom hlau, iav, thiab ceramic.Tsis zoo li hlau, yas yuav muaj kev nkag mus, uas yog deformation tshwm sim los ntawm lub sij hawm ntev raug rau ib tug tas li load.
Lub zog tensile, siv los qhia cov khoom siv lub zog tag nrho, yog qhov siab tshaj plaws uas nws tuaj yeem tiv taus ua ntej nws tawg.Corrosion resistance piav qhia txog cov khoom muaj peev xwm los tiv thaiv kev puas tsuaj los ntawm huab cua, noo noo, lossis lwm yam nruab nrab.Hnav tsis kam qhia tias muaj peev xwm tiv thaiv kev puas tsuaj los ntawm kev sib cuag nrog lwm qhov chaw.Toughness piav qhia txog cov khoom muaj peev xwm nqus tau lub zog ua ntej tawg, thaum hardness (feem ntau ntsuas raws li indentation hardness) piav qhia txog nws qhov tsis kam mus rau qhov deformation mus tas li.Impact resistance yog qhov ntsuas ntawm cov khoom muaj peev xwm nqus tau lub zog poob siab ua ntej tawg.
- PTFE tiv taus cov tshuaj feem ntau, feem ntau tiv taus qhov kub thiab txias, thiab muaj kev sib txhuam qis, tsis muaj qhov chaw- PTFE feem ntau tiv taus qhov kub thiab txias dua li lwm cov fluoropolymers, xws li FEP thiab ETFE- av tiav- Xim yog opaque dawb- Standard kam rau ua.
