I-Polyurethane (PU) ne-polyvinyl chloride (PVC) yizinto ezimbili ezithandwa kakhulu ezisetshenziswa kuzoIpayipi likathayela lensimbi engagqwali.Zombili zenziwe ngohlobo lwe-thermoplastic, kodwa kukhona umehluko omkhulu phakathi kwazo.Ngenxa yalesi sizathu, i-PVC ifaneleka kakhulu kwezinye izinhlelo zokusebenza, kuyilapho i-polyurethane nayo ingcono kune-PVC kwezinye izinhlelo zokusebenza.
Ipayipi le-PVC
I-PVC nayo ifaneleka kakhulu ekudleni, ukuchelela, imikhiqizo yobisi kanye nezicelo zezokwelapha.Kodwa-ke, ngenxa yokumelana kwayo ngokuqinile nesimo sezulu kanye nezinto eziningi zamakhemikhali, ingasetshenziswa ngezinjongo ezengeziwe.
Amapayipi e-PVC atholakala ngezinhlobo ezinzima, eziphakathi noma ezilula futhi angaqiniswa.Ngakho-ke, ipayipi le-PVC liyadingeka kunoma yisiphi isicelo.Kodwa-ke, ipayipi le-PVC linabo ubuthakathaka bayo.Ayihambisani namanye amafutha, amakhemikhali noketshezi, futhi izophuka ngokuhamba kwesikhathi.Ngenhlanhla, i-TPC futhi inamapayipi e-PVC akhethekile amelana nowoyela anolayini olukhethekile lokuvikela lesi simo.
Ipayipi le-polyurethane (PU)
Ipayipi le-polyurethane ligcwalisa inkinga okunzima ukuyixazulula i-PVC futhi inokumelana okuqinile noketshezi oluningi olususelwa ku-petroleum namakhemikhali.Yingakho amapayipi e-PU evame ukusetshenziswa emigqeni yamafutha.Izinga lokushisa eliphansi akuyona inkinga kumapayipi e-polyurethane.
Ukwengeza, izinhlelo zokusebenza zokucindezela okuphezulu zingenye indawo lapho amapayipi e-polyurethane ekhanya ngempela, ngoba enza kahle kulezi zinhlelo zokusebenza.Kodwa-ke, i-polyurethane ayinambitheki njenge-PVC, ngakho-ke ayilungele ezolimo noma imboni yokudla.
Amapayipi e-PVC ahlukaniswe abe izinhlobo eziningi, njengepayipi eliyisicaba, ipayipi eliboshwe ngensimbi, ipayipi lomlilo elinerabha elinepayipi kanye nepayipi lokumunca.Ekhaya, uzothola amapayipi e-PVC ngemuva kwendlu, ngaphansi kweshawa yokugezela kanye nesinki yasekhishini.
Iya emotweni yakho futhi uzothola ukuthi ipayipi le-PVC lidlala indima ebalulekile ekusebenzeni kwenjini yakho.Ipayipi le-PVC lisebenzisa i-pressure vent ku-crankcase, ukuze uwoyela ungachithi uphawu.
Abalimi basebenzisa imibhobho ye-PVC yokumunca insimbi kanye ne-spiral suction ukuze banisele amapulazi futhi bafafaze izitshalo ngezibulala-zinambuzane nezithasiselo.Baphinde bayisebenzise njengesisetshenziswa sokudlulisa ukuthutha okusanhlamvu, ufulawa, ngisho negesi nophethiloli.Kuzicelo zezimboni, amapayipi e-hydraulic PVC asetshenziswa emishinini ezitshalweni zokukhiqiza.
Embonini kawoyela negesi yemvelo, ipayipi eliqinisiwe lenza ipayipi le-PVC limelane nokugqwala futhi livikeleke.Lokhu kuyenza ibe yinketho efanelekile yokuhambisa uketshezi olunengcindezi ephezulu kanye neziqhumane namagesi.Ukuqinisa okufanayo futhi kwenza kube usizo ukudlulisa udaka ngepayipi lokumunca embonini yokwakha, yamakhemikhali neyezimoto.
Ipayipi eliqiniswe nge-PVC eliqinisiwe lisetshenziswa kakhulu kwezolimo, ukudoba, ubunjiniyela kanye nempahla yasendlini.Ingakwazi ukuthutha uketshezi namagesi, njengamanzi, i-lye, uwoyela, i-asidi, umoya-mpilo negesi.Njengoba ubona, amapayipi e-PVC asetshenziswa kabanzi emhlabeni jikelele.Eqinisweni, ingenye yamapayipi asetshenziswa kakhulu embonini ye-PVC, ebalwa ngaphezu kwe-82% yokuthengiswa kwepayipi.Lokhu kungenxa yokuthi i-PVC ibiza kakhulu.Ngaphezu kwalokho, ifaneleka kakhulu izinhlelo zokusebenza ezivezwe emazingeni okushisa aphezulu, emisebeni ye-ultraviolet noma amakhemikhali.Kuphinde kube yipayipi elilula, elisetshenziswe ezimbonini eziningi ezahlukene, ngakho liwumkhiqizo odayiswa kakhulu.
