Cov yam ntxwv ua haujlwm
1. Tsawg kev sib txhuam coefficient: PTFE muaj qhov sib txhuam coefficient tsawg heev, kwv yees li 0.04, uas ua rau kev sib txhuam quab yuam tsim los ntawm lub nplhaib foob thaum lub sij hawm txav me me, yog li txo qis kev siv hluav taws xob thiab kev tsim hluav taws xob. Qhov kev sib txhuam qis no yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv qhov chaw kub kub, vim nws pab tswj kev ua haujlwm ruaj khov ntawm cov khoom siv.
2. Kev ruaj ntseg zoo: PTFE yuav tsis dhau thermal expansion lossis deformation ntawm qhov kub thiab txias thiab muaj qhov ruaj khov zoo. Qhov no txhais tau hais tias txawm tias qhov kub thiab txias npaum li cas, PTFE lub nplhaib sealing tuaj yeem tswj tau nws cov qauv qub thiab qhov loj me, yog li ua kom muaj kev sib khi ntawm cov khoom siv.
3. Cov khoom siv hluav taws xob zoo: PTFE yog cov khoom siv hluav taws xob zoo heev nrog cov rwb thaiv tsev siab thiab lub zog dielectric. Qhov no txhais tau hais tias kev siv lub nplhaib PTFE foob tuaj yeem tiv thaiv qhov xau ntawm tam sim no, yog li ua kom muaj kev nyab xeeb ntawm cov khoom siv.
4. Cov khoom siv tshuaj: PTFE yog inert rau feem ntau cov tshuaj thiab yuav tsis corroded los ntawm feem ntau acids, alkalis, thiab organic solvents. Qhov no tso cai rau PTFE foob kom tswj nws qhov kev ua tau zoo hauv ntau qhov chaw tshuaj lom neeg.
Qhov zoo
1. Qhov kub thiab txias adaptability. Lub nplhaib PTFE foob muaj qhov kub thiab txias hloov tau zoo thiab tuaj yeem siv tau ntev ntawm qhov kub txog li 260C. Qhov no ua rau nws zoo tagnrho rau cov khoom siv kub kub
xaiv.
2. Hnav tsis kam: Vim tias PTFE muaj qhov sib txhuam coefficient qis thiab qhov zoo ntawm qhov ruaj khov, lub nplhaib sealing muaj lub neej ua haujlwm ntev. PTFE sealing nplhaib tuaj yeem tswj tau qhov zoo sealing nyhuv txawm nyob rau hauv nquag tsiv teb. ua ke,
3. Yooj yim rau nruab: Cov duab thiab qhov loj ntawm PTFE sealing nplhaib yog ruaj khov thiab yooj yim rau nruab thiab tswj. Nws tuaj yeem ntsia tau yooj yim hauv qhov chaw txawm tias qhov chaw txwv.
4. Kev lag luam: Piv nrog rau lwm cov khoom siv high-end sealing, tus nqi ntawm PTFE sealing rings yog qhov tsim nyog. Xav txog nws cov kev ua tau zoo thiab kev pabcuam lub neej, PTFE sealing rings yog kev lag luam zoo heev.
Kev txwv
1. Tsis haum rau tag nrho cov tshuaj ib puag ncig: Txawm hais tias PTFE yog inert rau feem ntau cov tshuaj, nws tseem yuav puas nyob rau hauv ib co corrosive chemical ib puag ncig. Yog li ntawd, thaum siv lub nplhaib PTFE, koj yuav tsum xav txog nws qhov chaw siv tshuaj.
2. Txwv tsis pub kub kub tsis kam: Txawm hais tias polytetrafluoroethylene muaj qhov zoo ntawm qhov kub thiab txias adaptability, nws qhov kub-kub kuj tseem txwv los ntawm nws cov qauv tshuaj. Tshaj li qhov kub thiab txias, lub nplhaib PTFE foob tuaj yeem decompose lossis deform, cuam tshuam rau nws txoj haujlwm thiab kev pabcuam lub neej.
3. rhiab heev rau hluav taws xob: PTFE yog ib qho rhiab heev rau cov hluav taws xob, thiab cov hluav taws xob ntev ntev yuav ua rau nws degrade. Yog li ntawd, lwm yam ntaub ntawv tsim nyog yuav tsum tau xav txog thaum siv nyob rau hauv lub radioactive ib puag ncig.
Xaus
Tshwj xeeb, kev ruaj ntseg ntawm PTFE foob nplhaib yog pom nyob rau hauv nws zoo seem stability, tsis tshua muaj kev sib txhuam coefficient, thiab tshuaj lom neeg zog. Txawm hais tias nyob rau hauv qhov chaw kub kub, PTFE sealing nplhaib yuav tsis dhau thermal expansion lossis deformation, thiab tseem tuaj yeem tuav nws cov duab qub thiab qhov loj me, yog li ua kom muaj kev sib khi ntawm cov khoom siv. Tsis tas li ntawd, vim nws tsis tshua muaj kev sib txhuam coefficient thiab zoo seem stability, PTFE sealing rings muaj lub neej ntev kev pab cuam, txo qhov zaus ntawm kev hloov thiab tu nqi.
Lub tshav kub tsis kam ntawm PTFE foob rings yog xav txog nyob rau hauv lawv lub peev xwm los tswj lawv cov thawj kev ua tau zoo nyob rau hauv high-temperature ib puag ncig. Nyob rau hauv qhov chaw kub kub, feem ntau cov ntaub ntawv yuav raug puas los yog hloov, tab sis PTFE tuaj yeem tswj kev ua haujlwm ruaj khov. Qhov no txhais tau hais tias txawm tias qhov kub thiab txias npaum li cas, PTFE sealing nplhaib tuaj yeem tswj hwm nws qhov kev ua tau zoo, yog li ua kom ruaj khov ntawm cov khoom siv.
Yog li ntawd, "kev sib xyaw ua ke zoo tshaj plaws ntawm kev ruaj ntseg thiab kub tsis kam" txhais tau hais tias PTFE foob nplhaib tuaj yeem tswj hwm nws qhov kev ua tau zoo thiab zoo tib yam nyob rau tib lub sijhawm nyob rau hauv qhov chaw kub kub yam tsis muaj kev hloov pauv lossis kev puas tsuaj, yog li muab kev pabcuam zoo rau ntau yam kub kub. khoom siv. Muab cov nyhuv sealing txhim khu kev qha thiab kev pabcuam lub neej. Qhov kev sib xyaw ua ke zoo tshaj plaws no ua rau PTFE ntsaws ruaj ruaj yog ib qho kev xaiv zoo tshaj plaws rau cov ntawv thov kub.
