PTFE, zoo dua lub npe hu ua polymer, yog ib qho polymer uas tau txais qhov tseem ceeb hauv kev siv hauv kev lag luam thaum lub sijhawm thib ob ntawm lub xyoo pua nees nkaum.Nws tsis tshua muaj coefficient ntawm kev sib txhuam thiab inertness ua rau nws haum tsis tau tsuas yog rau cov tais diav, tab sis kuj rau cov ntsaws ruaj ruaj nyob rau hauv industrial li qub.Txawm li cas los xij, cov ntaub ntawv nthuav tawm cov khoom siv tsis zoo, xws li kev ntxhov siab (xws li poob ntawm qhov tawv nqaij nrog lub sijhawm) thiab qhov kub thiab txias, uas yuav ua rau muaj teeb meem hauv qee yam kev siv.
Ib daim ntawv thov uas PTFE tau ua pov thawj zoo rau lwm cov ntaub ntawv yog nyob rau hauv cov ntsaws ruaj ruaj siv nyob rau hauv industrial plug li qub.Kev lag luam ntsaws li qub yog siv los thauj ntau cov kua dej, thiab lawv tau raug rau cov kev xav tau, xws li tshuaj tua kab mob thiab kub siab.Cov ntsaws ruaj ruaj yuav tsum tau ua kom tau raws li qhov yuav tsum tau muaj cov tshuaj tiv thaiv, thaum tiv thaiv kom tsis txhob yaig txhua lub sijhawm.Lub siab xav txo cov nqi tsim khoom thaum txhim kho kev ua haujlwm tau ua rau muaj kev xav tau ntawm cov ntsaws ruaj ruaj, nrog kev xav tau ntau dua ntawm cov khoom siv.Yog li kev nkag siab zoo txog qhov kev ntxhov siab hauv lub foob raug faib li cas yog li xav tau.Tsis tas li ntawd, qhov tshwm sim ntawm kev ntxhov siab so thiab kev kub ntxhov yog qhov txaus siab thiab lawv yuav tsum tau coj mus rau hauv tus account ib yam nkaus, los kwv yees tus cwj pwm ntawm lub foob.
PTFE yog cov khoom tseem ceeb siv los kaw cov kua dej sab hauv thiab rau cov cua.Internal sealing yog muab los ntawmPTFE lub tes tshouas yog compressed ntawm lub cev thiab lub ntsaws, thaum sab nraud sealing yog guaranteed los ntawm PTFE sab saum toj foob.
PTFE yog ib qho polymer pom nyob rau xyoo 1938 los ntawm Roy Plunkett ntawm DuPont Company.Nws cov qauv tshuaj muaj xws li chains ntawm carbon atoms bonded ua ke, nrog ceg ntawm fluorine atoms txuas.Cov khoom siv feem ntau hu ua polytetrafluoroethylene (PTFE), thaum polymer yog ib lub npe lag luam ntawm DuPont Company.
PTFE tau dhau los ua cov khoom siv engineering tseem ceeb.Nws cov txiaj ntsig tseem ceeb yog nws cov cim tsis nplaum, tsis muaj zog, tsis kam tiv thaiv tshuaj lom neeg thiab muaj zog heev.Tsis tas li ntawd, cov khoom tshwj xeeb ntawm lub cev tuaj yeem txhim kho los ntawm kev ntxiv cov khoom sib xyaw ua ke lossis hloov cov txheej txheem tsim khoom.Qee qhov tsis zoo ntawm lub cev uas PTFE cov kev paub yog qhov siab tshaj plaws rau kev hloov pauv kub thiab tsis zoo rau kev nkag siab thiab kev ntxhov siab.Qhov nyuaj thiab tsis-linear xwm txheej ntawm cov yam ntxwv no nthuav tawm txoj haujlwm ilv rau txhua tus engineer uas xav kwv yees tus cwj pwm ntawm PTFE.
Lwm qhov tsis zoo uas PTFE raug kev txom nyem los ntawm nws yog nws cov viscosity siab uas ua rau kev txhaj tshuaj thiab tshuab moulding tsis yooj yim sua, tawm hauv kev tsim khoom kim dua, xws li sintering thiab extrusion, tsuas yog kev xaiv rau ib feem ntau lawm.
