Tshuaj lom neeg sib xyaw ua piv txwv thiab PTFE & Silicone Septa

Lub Tebchaws 26th, 2024
Cim npe: Septa Caps Tsum HPLC septa Septa Kev Muag Khoom Septa Kev Muag Khoom Septa Cap soj ntsuam cap HPLC Vials PTFE SAUN Silicone Sepicone
Hauv cov tshuaj soj ntsuam chaw soj ntsuam thiab cov chaw muaj kev lag luam, ua kom muaj kev lag luam sib txawv ntawm cov qauv thiab soutta yog qhov tseem ua rau kev tswj kom muaj txiaj ntsig zoo thiab kev nyab xeeb. Qhov no yuav tsum nkag siab cov ncauj lus kom ntxaws txog cov kuab tshuaj thiab cov thoob ntiaj teb sib cuam tshuam nrog soutta ntaub ntawvXws li polytetrosauruoroethylene (PTFE) thiab silicone, uas tuaj yeem ua rau muaj kev mob siab thiab kev sib cais, thiab thaum kawg cuam tshuam kev ua tau zoo.

Compatibility nrog polytetrafluoroethylene (PTFE)


Polytetrafluoroethylene (PTFE), feem ntau yog muaj ntau yam siv dav hauv cov gasket vim nws cov tshuaj zoo heev thiab tsis muaj kev tiv thaiv cov khoom. PTFE tiv thaiv ntau yam ntawm cov kuab tshuaj, suav nrog hydrocarbons, dej cawv, thiab cov acids thiab cov hauv paus. Qhov no ua rau nws xaiv qhov zoo tshaj plaws rau kev siv cov ntawv thov kev sib tw ua rau muaj kev txhoj puab heev.

Txawm li cas los xij, txawm hais tias nws cov tshuaj muaj zog tiv thaiv, PTFE yuav muaj kev txiav txim tsawg hauv qee cov xwm txheej. Piv txwv li, muaj zog oxidizers xws li concentrated sulfuric acid, nitricens xws li chlorine lossis fluorine compound nrog PTFE. Cov kev tawm tsam no tuaj yeem ua rauPTFE GACEETTSkom thuam thiab poob lawv cov khoom sib khi ua tau zoo dhau sijhawm.

Nws yog ib qho tseem ceeb kom nkag siab txog cov txheej txheem tshwj xeeb uas cov tshuaj no cuam tshuam nrog PTFE. Piv txwv li, feeb cov sulfuric acid tuaj yeem ua rau PTFE rau defluoricize, ua rau kev tsim ntawm hydrofluoric acid thiab carbonineous seem uas tuaj yeem cuam tshuam rau cov khoom siv gasket. Ib yam li ntawd, nitric acid tuaj yeem ua rau oxidative degradation ntawm PTFE, cuam tshuam nws cov khoom siv tshuab thiab kev sib khi ua tau zoo.

Kev sim txhij txhua thiab kev tshuaj xyuas yog qhov tseem ceeb los daws cov kev nyuaj siab no. Qhov no suav nrog kev txheeb xyuas tshuaj lom neeg sib xyaw ua ke cov kab ke thiab cov ntaub ntawv los ntsuas cov kev pheej hmoo txaus ntshai cuam tshuam nrog kev siv PTFE soutta nyob rau hauv ib puag ncig muaj oxidizers. Ib qho ntxiv, tswj tau cov qauv ntsuas PTFE me me raug nthuav tawm, tuaj yeem muab qhov pom tau zoo rau hauv kev ua tau zoo thiab cov khoom siv ruaj khov ntawm cov khoom siv.

Silicone Sib Xws


Silicone yog lwm cov khoom siv dav hauv cov gaskets thiab yog muaj txiaj ntsig zoo rau nws cov khoom siv yooj yim, muaj peev xwm kub ua rau muaj kev kub ntxhov.Silicone SeptasFeem ntau siv nyob rau hauv cov ntawv thov uas yooj thiab elasticity yog qhov tseem ceeb, xws li cov khoom siv kho mob, thiab ua cov khoom siv khoom siv khoom siv.

Silicones tau zoo sib xws nrog ntau yam tshuaj lom neeg thiab cov kuab tshuaj, tab sis qee cov tshuaj yuav ua rau muaj teeb meem. Piv txwv li, silicones yuav tsis haum rau siv nrog cov ntxhiab hydrocarbons, cov kua qaub muaj zog xws li cov roj thiab cov roj thiab roj nplua thiab roj ntau.

Kev sib cuam tshuam ntawm silicone nrog cov ntaub ntawv tsis sib xws tuaj yeem ua rau o, softening, lossis kev ntxhov siab ntawm cov roj gasket. Qhov no tuaj yeem cuam tshuam sealing kev ua tau zoo, ua rau xau, thiab cov txheej txheem paug thiab khoom siv.

Txhawm rau kom ntseeg tau qhov zoo, nws yog ib qho tseem ceeb rau kev txiav txim siab xws li tshuaj multe, ntsuas kub, thiab lub sijhawm ua haujlwm hauv kev ua haujlwm. Ua kev ntsuam xyuas kev sib raug zoo siv cov khoom siv roj me me

Nrhiav cov ntaub ntawv tshaj tawm ntawm PTFE \ / Silicone Septa? Dhia rau peb tsab xov xwm rau kev nkag siab tiav ntawm cov tseem ceeb no:Txhua Yam Koj Yuav Tsum Tau Paub: 137 Pre-SLIT PTFE \ / Silicone Septa Soutra Faqs

Kev Txij Nkawm thiab Kev Soj Ntsuam


Ntxiv rau kev xaiv cov ntaub ntawv tshaj tawm, kev coj ua thiab kev tshuaj ntsuam xyuas yog qhov tseem ceeb kom ntseeg tau tias kev ua haujlwm ntev ntev thiab lub kaw lus kev ncaj ncees. Tsis tas li no:

Tshawb xyuas SARAA rau cov cim ntawm kev hnav, puas tsuaj, lossis tsis zoo thaum niaj hnub saib xyuas kev saib xyuas.

Saib xyuas rau kev hloov pauv hauv kev sib khi ua haujlwm, xws li txov lossis siab hloov pauv, uas yuav qhia tau soutta teeb meem.

Siv kev tiv thaiv kev txiav txim tu thiab hloov soutta Ua ntej lawv mus txog qhov kawg ntawm lawv lub neej muaj txiaj ntsig lossis qhia cov cim ntawm kev tsis zoo.

Los ntawm kev coj ua kom ze rau kev siv tshuaj lom neeg, kev xaiv cov khoom, thiab kev xaiv, thiab cov koomhaum tuaj yeem txo cov kev pheej hmoo cuam tshuam nrog soutta Ua tsis tiav, kom ntseeg tau kev ntseeg siab, thiab tswj cov qauv kev nyab xeeb thiab ib puag ncig hauv lawv cov txheej txheem.
