I-Polyurethane (PU) kunye ne-polyvinyl chloride (PVC) zezona zinto zidumileyo zisetyenziswa kwiUmbhobho wenkcenkce yentsimbi engenastainless.Zombini zenziwe ngohlobo lwe-thermoplastic, kodwa kukho umahluko ophambili phakathi kwazo.Ngenxa yesi sizathu, i-PVC ifaneleka ngakumbi kwezinye izicelo, ngelixa i-polyurethane ingcono kune-PVC kwezinye izicelo.
Umbhobho wePVC
I-PVC ikwafaneleka kakhulu ukutya, ukunkcenkceshela, iimveliso zobisi kunye nezicelo zonyango.Nangona kunjalo, ngenxa yokuxhathisa okunamandla kwimozulu kunye neekhemikhali ezininzi, ingasetyenziselwa iinjongo ezininzi.
Imibhobho yePVC ifumaneka kwiintlobo ezinzima, eziphakathi okanye ezilula kwaye zinokuqiniswa.Ke ngoko, umbhobho wePVC uyafuneka kuso nasiphi na isicelo.Nangona kunjalo, i-hose ye-PVC inabo ubuthathaka bayo.Ayihambelani nezinye ii-oyile, iikhemikhali kunye nolwelo, kwaye iya kuphuka ngokuhamba kwexesha.Ngethamsanqa, i-TPC ikwanayo imibhobho yePVC ekhethekileyo enganyangekiyo yeoli enelinen ekhethekileyo ukuthintela le meko.
Umbhobho wePolyurethane (PU)
Ithumbu lePolyurethane lizalisa ingxaki ekunzima ukuyicombulula iPVC kwaye inokumelana ngokuqinileyo nolwelo oluninzi olusekelwe kwipetroleum kunye neekhemikhali.Kungenxa yoko le nto ii-PU hoses zihlala zisetyenziswa kwiintambo zamafutha.Ubushushu obuphantsi abuyongxaki kwimibhobho ye-polyurethane.
Ukongezelela, izicelo eziphezulu zoxinzelelo zingenye indawo apho i-polyurethane hoses ikhanya ngokwenene, kuba yenza kakuhle kwezi zicelo.Nangona kunjalo, i-polyurethane ayikho incasa njengePVC, ngoko ayifanelekanga kwezolimo okanye kwishishini lokutya.
Imibhobho ye-PVC yahlulwe yaba ziindidi ezininzi, njengethumbu elisicaba, ithumbu elilukiweyo lentsimbi, ithumbu lomlilo elinerabha elineentambo kunye nethumbu lokufunxa.Ekhaya, uya kufumana imibhobho yePVC ngasemva kwendlu, phantsi kweshawari yokuhlambela kunye nesinki yasekhitshini.
Yiya kwisithuthi sakho kwaye uya kufumanisa ukuba umbhobho wePVC udlala indima ebaluleke kakhulu ekusebenzeni kwenjini yakho.Umbhobho we-PVC usebenzisa i-pressure vent kwi-crankcase, ukwenzela ukuba i-oyile ayiyi kuvuthela isitywina.
Amafama asebenzisa intsimbi yokufunxa intsimbi kunye nemibhobho yePVC yokunkcenkceshela ukunkcenkceshela umhlaba wasefama nokutshiza izityalo ngezibulali zinambuzane kunye nezongezelelo.Bakwayisebenzisa njengesixhobo sokuhambisa ukutya okuziinkozo, umgubo, kunye negesi kunye namafutha.Ukusetyenziswa kwemizi-mveliso, i-hydraulic PVC hoses isetyenziswa koomatshini kwizityalo zokuvelisa.
Kwishishini le-oyile kunye negesi yendalo, i-hose eyomeleziweyo yenza i-PVC ye-hose ye-corrosion inganyangeki kwaye i-anti-static.Oku kuyenza ibe lukhetho olufanelekileyo lokuhambisa uxinzelelo oluphezulu kunye nolwelo oluqhumayo kunye neegesi.Ukomelezwa okufanayo kukwenza kube luncedo ukuhambisa i-sludge ngombhobho wokufunxa kumashishini okwakha, amachiza kunye neemoto.
Ithumbu eliqiniweyo lePVC lisetyenziswa kakhulu kwezolimo, ukuloba, ubunjineli kunye nempahla yasekhaya.Inokuthutha ulwelo kunye neegesi, ezifana namanzi, i-lye, ioli, i-asidi, i-oksijini kunye negesi.Njengoko ubona, imibhobho yePVC isetyenziswa kakhulu kwihlabathi liphela.Enyanisweni, yenye yezona zinto zisetyenziswa kakhulu kwimibhobho ye-PVC, ibalwa ngaphezu kwe-82% yokuthengisa i-hose.Oku kungenxa yokuba iPVC ibiza kakhulu.Ukongeza, ifanelekile kakhulu kwizicelo ezivezwe kumaqondo obushushu agqithisileyo, imisebe ye-ultraviolet okanye iikhemikhali.Ikwangumbhobho okhanyayo, othe wasetyenziswa kumashishini amaninzi awohlukeneyo, ngoko ke yeyona mveliso ithengiswa kakhulu.
