Seb cov khoom noj-qibTeflon hosesMuaj peev xwm xeem dhau high-kub chav yog nyob ntawm cov khoom siv tshwj xeeb thiab kev siv cov xwm txheej. Hom khoom noj-qib-teflon suav nrog PTFE, FEP, thiab pfa. Ntawm lawv, PTFE thiab PTFE muaj qhov kub tau zoo, thiab lub sijhawm ntev siv kub yuav ncav cuag 26 {8} degree. FEP yog qis dua me ntsis, nrog qhov siab tshaj plaws kev siv kub ntawm 200 degree. Kev kub nyhiab hauv cov khoom noj khoom haus hauv kev ua zaub mov noj, feem ntau muaj qhov kub ntawm {}}}. 3 mpa. Hauv qhov no, PTFE thiab PTFE thiab PFA cov leeg muaj peev xwm tiv thaiv nws thiab yuav tsis muaj teeb meem rau kev siv tas li rau ntau xyoo. Cov leeg ntawm FEP tseem tuaj yeem siv tau rau hauv chav qis dua 180 degree rau lub sijhawm luv luv, tab sis ntev-lub sijhawm kub yuav ua rau lub raj muag muag thiab txo nws lub zog.
Txawm li cas los xij, thaum xaiv lub raj, koj yuav tsum tshawb xyuas seb nws puas muaj ntawv pov thawj-kawm ua khoom noj, xws li Asmeskas cov ntawv pov thawj lossis cov khoom noj nyob hauv tsev. Cov ntaub ntawv raw ntawm cov zaub mov-qib teflon yog ntawm siab purity, tsis muaj lwm yam ntxiv ntxiv thaum lub sij hawm cov khoom siv ntau lawm yuav ua rau muaj kev kub ntxhov yuav ua rau muaj kev kub ntxhov. Qhov no tseem ceeb heev. Txawm hais tias qee qhov kev lag luam Teflon teflon yog tseem tshav kub-resistant, tej zaum yuav muaj impurities nyob rau hauv cov ntaub ntawv raw thiab lawv tsis tuaj yeem siv nyob rau hauv cov zaub mov noj.
Tsis tas li ntawd, kev kub siab xaim hluav taws xob yuav tsum them sai sai rau txoj kev sib txuas ntawm cov kav dej. Yog tias koj siv cov fittings ceev lossis xov sib txuas, tej zaum yuav muaj teeb meem nrog sib foob ntawm kev laus thaum muaj kub. Nws yog qhov zoo tshaj plaws los xaiv cov vuam kub-yaj vuam lossis flared fittings kom ntseeg tau tias tsis muaj chav so ntawm kev sib txuas.
Feem ntau, ntev npaum li koj xaiv cov khoom siv tau (PTFE lossis PFA yog qhov kev tsim tawm ntawm cov kev teeb tsa, thiab ua kom muaj kev ua kom huv thiab ntxuav tawm, xws li kev npaj khoom noj thiab kev npaj khoom noj.
