Niaj hnub no, ntau cov khoom lag luam sawv tawm hauv kev tsim cov thev naus laus zis thiab kev lag luam, thiab PTFE raj yog ib qho ntawm cov khoom lag luam uas ua lub luag haujlwm tseem ceeb hauv ntau yam.Tab sis koj puas tau pom qhov kev laus ntawmPTFE tubes?Qhov kev ua tau zoo ntawm PTFE raj yuav txo qis tom qab kev laus.Yog li yuav tsum tau ua ntau yam kev ntsuas los tiv thaiv kev laus tom qab theem ntawm kev tsim cov PTFE hlab.Kev laus ntawm PTFE hlab yog ntuj thiab tsis tuaj yeem tiv thaiv, tab sis tib qho uas koj tuaj yeem ua tau yog ua kom qeeb ntawm kev laus. PTFE tubes.Txhawm rau kom txo qis kev laus ntawm cov hlab PTFE, koj yuav tsum ntxiv dag zog rau kev siv cov raj PTFE thiab siv cov kev ntsuas los tiv thaiv qhov xwm txheej no.Ntawm noBesteflon muab koj plaub txoj kev loj los ua kom qeeb ntawm kev laus ntawm koj lub raj PTFE.
1. Thaum xaiv cov khoom sizing ntawm PTFE hlab, koj yuav tsum siv sulfur curing system thaum twg los tau.Vim lub tshav kub tsis kam ntawm nws cov roj hmab vulcanized, nws tuaj yeem hloov kho los ntawm kev txo lossis tsis txhob siv cov tshuaj sulfur, uas tuaj yeem txo qis lossis tshem tawm polysulfide crosslinks thiab tsim cov monosulfide los yog disulfide crosslinks, yog li qeeb cov laus ntawmPTFE cov raj.
2. Txhawm rau kom ntseeg tau tias cov khoom ua tiav qhov kev xav tau cua sov, yuav tsum siv peroxide.Hauv qhov no, peroxide vulcanization tsim cov pa roj carbon zoo dua thermal stability thiab carbon cross-linking bonds.
PTFE tube chaw tsim tshuaj paus kuj sau tseg tias koj yuav tsum tau them tshwj xeeb mloog mus rau lwm yam additives nyob rau hauv kev siv ntawm peroxides.Piv txwv li, kev xaiv cov tshuaj antioxidants yuav tsum nruj dua, vim tias lawv feem ntau cuam tshuam nrog vulcanization ntawm peroxides.Yog li ntawd, koj tuaj yeem siv cov roj paraffin, ib qho tshuaj ntxiv uas yuav tsis cuam tshuam nrog peroxide vulcanization.
3. Tsis tas li ntawd, txhawm rau tiv thaiv kev faib tawm ntawm cov peroxide cation thiab tsis txhob vulcanization ntawm lub siab-siab hose (qhia los ntawm qis hardness, qis modulus thiab siab compression thiab ntev deformation), koj yuav tsum siv peroxide kom txo tau. tus nqi ntawm acidic muab tub lim.Yog tias ua tau, qhov sib ntxiv ntawm cov tshuaj alkaline (xws li zinc oxide lossis magnesium oxide) feem ntau txhim kho qhov kev sib txuas ntawm kev sib txuas ntawm peroxide.
4. Thaum tsim khoomPTFE cov hlab ntsha, qee cov tshuaj ntxiv tuaj yeem muab ntxiv, xws li antioxidants, thiab alkaline tebchaw, thiab lwm yam, txhawm rau txhim kho kev sib txuas ntawm kev sib txuas ntawm peroxides thiab ncua kev laus.PTFE cov raj.
