Kumjongi oqhelekileyo, kukho umahluko omncinci phakathi kombhobho wePVC kunye nombhobho we-UPVC.Zombini ziyimibhobho yeplastiki esetyenziswa kakhulu ekwakheni.Ngaphaya kokufana okungaphaya, ezi ntlobo zimbini zemibhobho zenziwe ngokwahlukileyo kwaye ke zineepropati ezahlukileyo kunye nezicelo ezahlukileyo kancinci kwisakhiwo kunye nezinye iinkqubo zoshishino kwaye uninzi lokuvezwa komsebenzi wokulungisa kumbhobho weplastiki kukwiPVC kune-UPVC.
Ukwenziwa
I-PVC kunye ne-UPVC ubukhulu becala zenziwe ngemathiriyeli efanayo.I-Polyvinylchloride yipolymer enokuthi ifudunyezwe kwaye ibunjwe ukwenza iikhompawundi ezinzima kakhulu, ezomeleleyo ezifana nemibhobho.Ngenxa yeepropathi zayo eziqinileyo xa sele zenziwe, abavelisi bahlala bedibanisa iipolymers ezongezelelweyo zeplastiki kwi-PVC.Ezi polymers zenza umbhobho wePVC ugobe ngakumbi kwaye, ngokubanzi, kulula ukusebenza nawo kunokuba uhlala ungekho iplastiki.Ezo zixhobo zeplastiki zishiywa ngaphandle xa kuveliswa i-UPVC-igama lifutshane kwi-polyvinylchloride engaxutywanga-ephantse yaqina njengombhobho wentsimbi.
Ukuphatha
Ngeenjongo zokufakela, umbhobho wePVC kunye ne-UPVC ziphathwa ngendlela efanayo.Zombini zinokusikwa ngokulula ngeesaha zeplasitiki zokusika okanye izixhobo zombane ezenzelwe ukusika umbhobho wePVC kwaye zombini zidityaniswe kusetyenziswa iikhompawundi zokuncamathisela kunokusebenzisa i-soldering.Ngenxa yokuba umbhobho wePVC awuqulathanga iipholima zeplastiki ezenza iPVC ibe bhetyebhetye, kufuneka isikwe ngokugqibeleleyo ngokobungakanani kuba ayikuvumeli ukupha.
Usetyenziso
Umbhobho we-PVC usetyenziselwa indawo yobhedu kunye nemibhobho ye-aluminiyam kumanzi angaselwayo, ukubuyisela imibhobho yesinyithi kwimigca yenkunkuma, iinkqubo zokunkcenkceshela kunye neenkqubo zokujikeleza kwamanzi.Ngenxa yokuba ixhathisa ukubola kunye nokuthotywa kwemithombo yebhayoloji, yimveliso ehlala ixesha elide ukuyisebenzisa kwiinkqubo zemibhobho.Isikwe ngokulula kwaye amalungu ayo akafuni ukusoda, ukuqhobosheka ngeglu endaweni yoko, kwaye inika isixa esincinci sokupha xa imibhobho ingalingani ngokugqibeleleyo, ngoko ke umbhobho wePVC ukhethwa rhoqo ngabantu abancedisayo njengenye indlela ekulula ukuyisebenzisa kwintsimbi. imibhobho.
Ukusetyenziswa kwe-UPVC akuxhaphakanga kangako kwimibhobho yamanzi eMelika, nangona ukuqina kwayo kuyincedile ukuba ibe yeyona nto ikhethwayo kwimibhobho yamanzi amdaka, ithatha indawo yombhobho wentsimbi.Ikwasetyenziswa rhoqo ekuveliseni iinkqubo zangaphandle zokuhambisa amanzi njengemibhobho yamanzi.
Ekuphela kohlobo lombhobho weplastiki ekufuneka usetyenziselwe ukuhanjiswa kwamanzi okusela ngumbhobho we-cPVC.
