Nyob rau hauv xyoo tas los no, ntau yam kev lag luam, peb tus kheej suav nrog, tau txav los ntawm ntuj roj hmab mus rauhluavtaws.Tab sis dab tsi yog qhov txawv ntawm ob?Dab tsi yog qhov sib txawv ntawm cov khoom sib txawv thiab lawv puas tuaj yeem tiv thaiv cov roj hmab hoses?Kab lus hauv qab no tau muab tso ua ke los teb cov lus nug no thiab ntau ntxiv.
Ntuj Roj Hmab vs Synthetic Roj Hmab: Dab tsi yog qhov txawv?
Ntuj roj hmab los ntawm Hevea brasiliensis (los yog Pará roj hmab tsob ntoo) uas yog hom nroj tsuag hauv tebchaws Brazil.Cov roj hmab ntuj yog cov khoom siv elastomer nrov heev, siv ntau yam kev siv thiab kev lag luam.
Cov roj hmab hluavtaws yog tsim los ntawm cov khoom siv hluavtaws thiab yog tsim los ntawm ntau hom polymers.Vim nws cov khoom siv dag zog, nws tuaj yeem hloov kho thiab muaj ntau yam khoom sib txawv ntxiv rau nws.
Feem ntau, cov roj hmab ntuj suav hais tias muaj zog thiab hloov tau yooj yim dua, tab sishluavtaws roj hmabmuaj qhov zoo ntawm kev ua tshuaj thiab kub resistant.Synthetic roj hmab kuj muaj txiaj ntsig los ntawm kev siv nyiaj ntau dua.
Dab tsi yog cov cuab yeej ntawm Synthetic Rubber Hoses?
Feem ntau cov khoom ntawmhluavtaws roj hmab tubingsuav nrog:
Flexibility - Roj hmab hoses yog qhov zoo tagnrho rau txhua daim ntawv thov uas yuav tsum muaj lub hose hloov tau yooj yim lossis lub raj.Roj hmab paub tias muaj peev xwm khaws tau nws qhov yooj yim, thaum kuj tseem tiv taus kinks thiab abrasions.
Kev ntsuas kub tsis kam - Cov roj hmab ntuj (qhov tseeb ntau cov khoom siv hose) tsis tuaj yeem tswj qhov kub thiab txias zoo li cov roj hmab hluavtaws ua.
Tshuaj tiv thaiv - Ib qho hluavtaws roj hmab hose yeeb nkab yog qhov zoo dua ntawm kev tiv thaiv cov tshuaj thaum piv rau cov roj hmab ntuj, thiab lwm yam khoom siv siv rau kev tsim cov hose, uas tuaj yeem ua rau lub sijhawm tsis muaj zog.
Dab tsi yog qhov txawv ntawm Synthetic Rubber?
Raws li cov roj hmab hluavtaws tuaj yeem muaj cov khoom sib txawv, muaj ntau hom sib txawv.
EPDM - Ethylene Propylene Diene Monomer (EPDM) yog cov tshuaj tiv thaiv rau feem ntau cov tshuaj, sib nrug los ntawm cov rog thiab cov roj ntxhia.UV thiab huab cua-resistant, EPDM roj hmab hoses kuj muaj qhov kub-resistant.
NBR - Nitrile butadiene roj hmab (NBR), thaum tsis tiv taus huab cua li EPDM, muaj kev tiv thaiv siab rau cov roj ntxhia, ua rau nws tsim nyog rau kev siv lub hose yog nyob rau hauv kev sib cuag nrog roj thiab roj.
SBR - Styrene butadiene roj hmab (SBR) yog lub hom phiaj dav dav thiab pheej yig dua thaum piv rau EPDM thiab NBR.Thaum tsis muaj huab cua tsis kam, nws zoo ib yam li EPDM hauv nws cov tshuaj tiv thaiv.
TPE - Ntawm no ntawm Lanboom, peb cov kev tshawb fawb thiab thev naus laus zis tau siv cov txiaj ntsig ntawm cov roj hmab thiab PVC los tsim cov thermoplastic polyester elastomer (TPE).Hom roj hmab no ua ke nrog PVC kom muaj kev txhim kho yooj yim ntawm qhov kub thiab txias, raws li tus qauv PVC tuaj yeem poob nws qhov yooj yim thiab tawg hauv cov xwm txheej no.TPE kuj tseem tsis muaj taint-dawb thiab WRAS-pom zoo, ua rau nws tsim nyog rau kev siv dej haus.
TPV - Peb nyob rau pem hauv ntej ntawm kev tsim cov thermoplastic vulcanizates (TPV).TPVs yog cov ua haujlwm siab elastomers nrog tus nqi zoo sib xws rau cov roj hmab.Lawv tso saib ntau cov yam ntxwv thiab kev ua tau zoo ntawm cov roj hmab, tab sis muaj zog dua, hnyav dua, thiab 100% rov ua dua tshiab.
Cov ntawv thov dab tsi yog Synthetic Rubber Hoses Zoo Tshaj Rau?
Vim lawv cov khoom, hluavtaws roj hmab hoses muaj ntau yam thiab tuaj yeem siv rau ntau daim ntawv thov.Nov tsuas yog qee qhov:
Industrial - Synthetic roj hmab hoses feem ntau yog siv nyob rau hauv industrial cheeb tsam.Lawv cov tshuaj tiv thaiv ua rau lawv zoo tagnrho rau cov ntawv thov uas cuam tshuam rau kev hloov pauv huab cua, roj, lossis lubrication.
Kev tsim kho - Lawv qhov yooj yim thiab kev puas tsuaj ua rau lawv haum rau kev siv uas cuam tshuam nrog kev tsim kho.EPDM thiab NBR muaj kev tiv thaiv huab cua ntau dua, ua rau lawv haum rau kev siv sab nraum zoov, nrog rau sab hauv tsev.
Dej - TPE, vim yog tsis muaj taint-dawb thiab WRAS-pom zoo, tuaj yeem siv rau cov ntawv thov uas cuam tshuam txog kev hloov pauv thiab xa dej haus.
Muaj ntau ntau hom roj hmab hluavtaws, txhua tus muaj nws tus kheej cov khoom, ua rau lawv haum rau cov kev siv sib txawv.Peb muab ntau hom roj hmab hoses sib txawv, ua kom yooj yim dua puas tau nrhiav cov khoom tsim nyog rau koj.Thov koj xav tias dawb los ntawm peb cov khoom lag luam, lossis yog tias koj twb pom qhov koj tab tom nrhiav, koj tuaj yeem tiv tauj ib tus tswvcuab ntawm peb pab pawg muag khoom zoo rau kev tsocai dawb.
