Phaj heat exchanger yog cov khoom siv hluav taws xob zoo heev, nws daim ntawv thov yog dav heev, phaj kub exchanger feem ntau cov ntsiab lus tseem ceeb yog phaj kub exchanger phaj thiab sealing gasket. Cov theem ntawm txoj kev loj hlob ntawm lub sealing gasket ncaj qha txiav txim siab theem ntawm kev loj hlob ntawm lub phaj kub exchanger, phaj kub exchanger sealing tsis ua hauj lwm yog ib tug loj heev ntau lawm tsis ua hauj lwm, ces lub phaj kub exchanger sealing gasket yog dab tsi kev ua tau zoo los tiv thaiv sealing nyhuv?
Qhov tseeb, nws yog cov nram qab no rau tus yam ntxwv, yog li ntawd lub phaj kub exchanger sealing gasket muaj zog sealing nyhuv.
Incompressibility
Cov roj hmab hluavtaws zoo li cov kua dej tuaj yeem hloov tau nws cov duab, ntawm chav kawm, nws tsis tuaj yeem ntws, thaum lub siab kom deform nws tom qab ploj ntawm extrusion siab, nws tuaj yeem rov qab los rau nws cov duab qub (uas yog, gasket hauv compression. txheej txheem ntawm nws lub ntim tsis hloov pauv, mus rau qhov loj ntawm lub siab hloov).
Lub zog
Yuav tsum muaj lub zog txaus los tiv thaiv lub siab extrusion kom nws mus rau hauv lub xeev sealing thiab tiv taus cov kua nruab nrab siab (piv txwv li, lub zog tensile ntawm cov roj hmab gasket, ruaj khov-extension zog thiab lwm yam khoom siv lub cev).
Plasticity
Cov txheej txheem yuav tsum tau hloov kho kom nws ua tiav ob qho tib si lub zog txaus kom ua raws li kev siv thiab cov yas txaus kom nws haum nruj rau cov hlau nto hauv qab qhov tsim nyog los tsim lub sealing muaj nuj nqi (lub gasket profile ua tau raws li cov duab ntawm cov khoom. sealing phaj grooves).
Kev nkag mus tsis kam
Synthetic rubber's polymer peb-dimensional mesh qauv muaj peev xwm tiv thaiv kev nkag mus ntawm cov kua uas muaj cov tshuaj sib txawv (media resistance).
Kub tiv taus
Cov roj hmab hauv cov ntaub ntawv polymer muaj qhov tsis zoo uas tag nrho cov khoom siv roj hmab hluavtaws tsuas yog siv tau rau hauv qhov ntsuas qhov nqaim ntawm qhov ntsuas kub. Yog li ntawd nws yog ib qho tseem ceeb uas cov formulation ntawm cov khoom yog ua tib zoo xaiv raws li qhov kub thiab txias yuav tsum tau rau daim ntawv thov.
Durability
Ntau yam ntawm cov khoom siv hluavtaws tshiab yog tus cwj pwm los ntawm kev pabcuam lub neej ntev dua li cov qauv qub vim yog siv cov khoom siv tshiab ntxiv uas txuas ntxiv rau kev pabcuam lub neej. Hauv qhov no, qhov kev xaiv raug ntawm cov khoom siv hluavtaws yog qhov tseem ceeb heev, txhua yam khoom siv roj hmab raws li cov khoom siv hluavtaws yuav tshwm sim los ntawm kev ntxhov siab, nyob rau hauv tus txheej txheem ntawm kev siv, vim yog cov tshuaj hloov pauv hauv cov khoom siv hluavtaws, thawj zaug sealing muaj nuj nqi yuav maj mam poob, thiab thaum lub sealing kev ua tau zoo qis dua qhov compression txwv, to yuav inevitably tshwm sim.
