Kev Tshawb Fawb Tom Qab PTFE's Temperature Resistance
Chemical Structure ntawm PTFE
PTFE qhov kub thiab txias tsis kam yog los ntawm nws cov qauv tshuaj tshwj xeeb. Ua los ntawm cov pa roj carbon thiab fluorine atoms, PTFE tsim ib lub zog, linear polymer saw. Cov pa roj carbon-fluorine bonds yog qhov ruaj khov heev, xav tau lub zog tseem ceeb rau kev tawg. Qhov kev ruaj ntseg molecular no txhais tau rau qhov ua tau zoo ntawm cov cua sov, tso cai rau PTFE coated fabrics los tswj lawv txoj kev ncaj ncees txawm tias qhov kub siab.
Crystalline thiab Amorphous Regions
PTFE tus qauv muaj ob qho tib si crystalline thiab amorphous cheeb tsam. Cov cheeb tsam crystalline muab lub zog thiab qhov ruaj khov, thaum cov cheeb tsam amorphous muab qhov yooj yim. Qhov ob qhov xwm txheej no ua rau PTFE lub peev xwm los tiv thaiv qhov kub thiab txias yam tsis muaj kev cuam tshuam nws lub cev. Raws li qhov kub thiab txias, cov khoom siv maj mam hloov mus, tso cai rau nws hloov mus yam tsis muaj qhov tsis ua haujlwm tam sim ntawd. Cov cuab yeej no tseem siv tau rau Teflon coated ntaub , uas tau txais txiaj ntsig los ntawm tib yam kev ua haujlwm zoo.
Thermal Decomposition Point
Thaum PTFE boasts impressive tshav kub kuj, nws yog ib qho tseem ceeb kom nkag siab txog nws thermal decomposition point. PTFE pib degrade ntawm kwv yees li 400 ° C (752 ° F), tso tawm cov khoom tsim kev puas tsuaj. Txawm li cas los xij, PTFE txheej ntawm cov ntaub feem ntau pib poob kev ua haujlwm zoo ua ntej lub ntsiab lus no, uas yog vim li cas qhov kev pom zoo siab tshaj plaws ua haujlwm kub qis dua. Kev nkag siab txog cov kev txwv no yog qhov tseem ceeb rau kev nyab xeeb thiab siv tau zoo ntawm PTFE coated fabrics hauv cov ntawv thov kub.
Cov yam ntxwv cuam tshuam rau qhov kub thiab txias ntawm PTFE Coated Fabrics
Base ntaub ntaub
Kev xaiv ntawm lub hauv paus ntaub ho cuam tshuam rau tag nrho cov kub tsis kam ntawm PTFE coated daim ntaub. Fiberglass yog ib qho nrov substrate vim nws qhov kub thiab txias tsis kam thiab qhov ntev stability. Lwm cov ntaub ntawv xws li aramid lossis polyester tuaj yeem siv rau cov ntawv thov tshwj xeeb tab sis feem ntau muab qhov ntsuas kub qis dua. Kev sib koom ua ke ntawm lub hauv paus ntaub thiab PTFE txheej txiav txim siab cov khoom sib xyaw ua haujlwm qhov kub thiab txias.
Txheej Thickness thiab Zoo
Lub thickness thiab zoo ntawm PTFE txheej ua lub luag haujlwm tseem ceeb hauv qhov kub thiab txias. Ib txheej txheej tuab feem ntau muab cov rwb thaiv tsev zoo dua thiab tiv thaiv tshav kub. Txawm li cas los xij, nws tsis yog hais txog qhov ntau; qhov zoo ntawm txheej, nrog rau nws cov uniformity thiab adherence rau lub hauv paus ntaub, yog ib qho tseem ceeb sib npaug. Hwm PTFE txheej nrog cov txheej txheem siab heev tuaj yeem muab cov cua sov ua haujlwm zoo dua piv rau cov qauv qib, tshwj xeeb tshaj yog nyob rau hauv Teflon coated ntaub.
Ib puag ncig tej yam kev mob
Cov xwm txheej ib puag ncig tuaj yeem cuam tshuam qhov kub thiab txias ntawm PTFE coated fabrics. Kev cuam tshuam rau UV hluav taws xob, tshuaj lom neeg, lossis kev ntxhov siab ntawm lub tshuab tuaj yeem ua rau cov txheej txheem degrade lub sijhawm, txo nws cov cua sov. Tsis tas li ntawd, muaj qee yam tshuaj los yog cov khoom paug tuaj yeem ua rau muaj kev puas tsuaj ntawm qhov kub thiab txias tshaj qhov xav tau. Yog li ntawd, nws yog ib qho tseem ceeb los xav txog tag nrho cov kev khiav hauj lwm ib puag ncig thaum soj ntsuam cov khoom siv kub muaj peev xwm.
