Roj hmab qhwv hlau yog hais txog cov txheej txheem ntau lawm, roj hmab thiab hlau tsim ua ke, feem ntau yog cov roj hmab qhwv hlau. Raws li kev faib tawm cov khoom, cov khoom tseem ceeb yog NBR qhwv hlau, silicone roj hmab qhwv hlau, ternary propylene roj hmab qhwv hlau, chloroprene roj hmab qhwv hlau, ntuj roj hmab qhwv hlau, fluorine roj hmab qhwv hlau, butadiene. Raws li cov khoom siv ntawm lub cev, cov khoom tseem ceeb yog cov roj hmab kub-npuaj hlau, hnav-tiv thaiv cov roj hmab-clad hlau, roj hmab kub tsawg-clad hlau, roj-resistant roj hmab-clad hlau, laus-resistant roj hmab-clad hlau, acid -alkali-resistant roj hmab-clad hlau, ozone-resistant roj hmab-clad hlau, thiab lwm yam. Cov xim no feem ntau dub, tab sis kuj pob tshab thiab ntsuab. Xim, xiav, ntshav, liab thiab lwm yam xim. Lub qhov ntev tuaj yeem kho tau raws li cov qauv lossis cov duab kos muab los ntawm cov neeg siv khoom. Hlau thiab tooj liab yog feem ntau siv rau hauv cov hlau no.
Tam sim no, tsis muaj ntau lub chaw tsim khoom lag luam uas tuaj yeem tsim cov roj hmab-npog cov hlau. Peb lub tuam txhab muaj cov kws tshaj lij kev tshawb fawb roj hmab thiab cov kws tshaj lij, tshwj xeeb hauv kev tshawb fawb khoom lag luam roj hmab. Tam sim no cov khoom lag luam tau thov mus rau ntau qhov chaw lag luam qib siab. Cov roj hmab xeb-cov xim hlau tau dhau los ua ib puag ncig ROHS daim ntawv pov thawj thiab zaub mov-qib FDA daim ntawv pov thawj. Tam sim no, lub ntsiab ntawm cov roj hmab cladding yog: roj hmab-clad hlau pas, roj hmab-clad hlau qhov chaw, roj hmab-clad roj hmab, roj hmab tsho, roj hmab-clad yas qhov chaw, roj hmab-clad nylon, roj hmab-clad ferrofluorocarbon, roj hmab-clad PTFE , thiab lwm yam.
Cov ntaub ntawv siv roj hmab feem ntau siv yog raws li nram no:
1. Fluororubber: Nws muaj qhov kub thiab tsis kam zoo, tuaj yeem siv rau hauv - 30 ~ 250 ~ C ib puag ncig, muaj zog oxidant tsis kam, roj tsis kam, acid thiab alkali tsis kam. Feem ntau siv rau hauv qhov kub thiab txias, lub tshuab nqus tsev siab thiab qhov chaw siab siab, haum rau roj ib puag ncig. Fluororubber yog dav siv hauv roj av thiab tshuaj lom neeg kev lag luam vim nws cov khoom zoo heev.
2. Cov roj hmab Silicone: Nws muaj qhov ua tau zoo rau qhov siab thiab tsis kub, tswj tau zoo elasticity hauv qhov kub ntawm - 70 - + 260 ~ C, thiab muaj qhov zoo ntawm ozone tsis kam thiab huab cua laus kuj tiv taus. Nws yog qhov tsim nyog rau kev sib khi gasket hauv cov tshuab cua sov. Kev rwb thaiv tsev, rwb thaiv tsev thiab khoom siv roj hmab kho mob tuaj yeem ua yam tsis muaj tshuaj lom.
3. NBR: Nws muaj cov roj ua tau zoo thiab tshuaj tsw qab kuab tshuaj, tab sis nws tsis tiv taus rau nruab nrab xws li ester thiab chlorination. Yog li no, NBR yog lub ntsiab roj-resistant.
4. chloroprene roj hmab: nws muaj roj zoo kuj, kuab tshuaj ua hauj, tshuaj nruab nrab tsis kam, tab sis tsis muaj ntxhiab roj tsis kam. Nws cov yam ntxwv yog huab cua tsis kam thiab huab cua laus. Hauv kev tsim khoom, chloroprene roj hmab feem ntau yog siv los ua cov qhov rooj thiab qhov rai ntim, diaphragms thiab cov khoom nqus dav dav.
5. Ethylene propylene trioxide: Nws muaj cov cua kub zoo, huab cua tsis kam thiab ozone kev laus ua haujlwm. Nws feem ntau yog siv cov qhov rooj thiab lub qhov rooj ntim thiab tsheb kev lag luam feem ntau dav.
6. Polytetrafluoroethylene composite gasket yog hom tshiab ntawm cov khoom sib khi uas yog ua los ntawm polytetrafluoroethylene thiab cov khoom lag luam zoo txhua yam roj hmab nrog cov txheej txheem tshwj xeeb ntau lawm. Nws ua ke cov yam ntxwv zoo ntawm polytetrafluoroethylene thiab roj hmab, yog li cov khoom lag luam muaj kev tiv thaiv zoo tiv thaiv, kub ua hauj, tsis muaj tshuaj lom, tsis muaj tshuaj tiv thaiv thiab ua haujlwm tau zoo. Elasticity thiab sealability.
