Umbhobho Wokuthintela Ioksijini we-PE-RT II
Intshayelelo yePipe ye-Oxygen Barrier ye-PE-RT II
Umbhobho wokuthintela ioksijini wohlobo lwe-GKBM PE-RT (EVOH) yimveliso ephuculweyo yombhobho wokufudumeza umgangatho we-PERT. Wenziwa kusetyenziswa inkqubo yokukhupha ioksijini enamaleko amathathu okanye amahlanu. Umaleko wangaphakathi (onamaleko amahlanu ziileko zangaphakathi nezangaphandle) ngumbhobho we-PE-RT, umaleko wangaphandle (onamaleko amahlanu yileko ephakathi) yimpahla yokuthintela ioksijini ye-EVOH, kwaye umaleko ophakathi yi-glue eshushu enyibilikayo. Uhlobo olutsha lombhobho odibeneyo. Ukongeza kuzo zonke iingenelo ze-PE-RT, umahluko omkhulu wombhobho wokuthintela ioksijini kukuba unokuthintela ngempumelelo ioksijini ekungeneni kwinkqubo kwaye ukhusele iindawo zesinyithi kwinkqubo kumonakalo we-oxidation. Kukho iimveliso ezingama-20 zizonke zemibhobho yokuthintela ioksijini yohlobo lwe-PE-RT (EVOH) II, ezahlulwe ngokweenkcukacha ezi-5 ezivela kwi-dn16-dn40.
Uhlu lweePipe zokuFudumeza uMgangatho we-PE-RT
1. Umahluko ophambili phakathi kwemibhobho yokuthintela ioksijini yohlobo lwe-PE-RTⅡ kunye nemibhobho ye-PE-RT, PE-X, PP-R, PE kunye neminye kukuba uhlobo lwe-PE-RTⅡ ludidi olunezigaba ezintathu oludityaniswe ngokwendalo lube yisigaba esinye, apho isigaba se-EVOH sivimba ioksijini. Amanzi okanye umoya ongena kumbhobho wandisa kakhulu ubomi benkonzo yeevalvu zesinyithi, iiswitshi, iibhoyila, abaqokeleli bamanzi kunye nezinye iindawo zesinyithi kwinkqubo yonke yemibhobho ezigugileyo ngenxa ye-oxidation. Ukuba umbhobho wokuthintela ioksijini usetyenziswa emanzini epompo, nokuba amanzi awahambi ixesha elide, akayi kubohla ngenxa ye-oxidation, kwaye iibhaktheriya eziphila kwioksijini azinakuyenza.
Umbhobho wodonga we-PE-RT wohlobo lwe-2.PE-RT II unokumelana nobushushu okuphezulu.
3. Ikwanayo nenzuzo yokuba ayithathi ndawo emva kokufakwa nokusetyenziswa kwemibhobho ye-PE-RT.
4. Ikwanazo neenzuzo zokuba ikhululekile emva kokufakwa nokusetyenziswa kwemibhobho ye-PE-RT.
5. Ikwanenzuzo yokuphucula imeko-bume emva kokufakwa nokusetyenziswa kwemibhobho ye-PE-RT.
6. Ikwanazo neenzuzo zobomi obude bemibhobho ye-PE-RT.
7. Ikwanazo neenzuzo zokugcinwa lula kwemibhobho ye-PE-RT.
8. Iipayipi zokuthintela ioksijini nazo zineempawu ezifanayo nezinye iipayipi zokufudumeza umgangatho ezimelana nobushushu obuphezulu: ukumelana ne-asidi, ukumelana ne-alkali, ukumelana nokugqwala, ukumelana nokwaluphala, okungenatyhefu kwaye okungenancasa, okungenamhlwa, ukumelana namanzi amancinci, okungekho scaling, okuthintela ukuqhekeka komkhenkce, okuthintela ukuvuza, ukulahleka kobushushu okuncinci, ukonga amandla, ucoceko, olunobuhlobo nokusingqongileyo, oluguquguqukayo kwaye kulula ukulugoba, kunye nokuphelisa uxinzelelo lokugoba olubandayo.
