Uyini umehluko phakathi kwe-UPVC ne-PVC?
Nakuba zombili izinhlobo zisetshenziswa kabanzi, kunomehluko phakathi kwe-UPVC ne-PVC.Eqinisweni, kunezindawo ezimbalwa ezizivikelayo, ake sibheke ukuthi zenziwa futhi zisetshenziswe kanjani.
inqubo yokukhiqiza
Ezimweni eziningi, zombili izinhlobo zenziwa nge-polymer polyvinyl chloride.Kodwa-ke, abakhiqizi abenza la mapayipi bangaphinde baxube ama-plasticizer ahlukahlukene enhlanganisweni ukuze kube lula ukusebenza ngawo.Uma lezi plasticizers zingasetshenziswa, ipayipi libizwa UPVC.
Izimfanelo
Umehluko phakathi kwamapayipi e-UPVC kanye ne-PVC nawo udlulela ezindaweni.Ama-Plasticizer asetshenziswa kumapayipi e-PVC, kanti ama-phthalates avame kakhulu.Lokhu kanye namanye ama-plasticizer angama-ester angenaphunga futhi angenambala.Uma zifakwe ku-PVC, zenza ipayipi likhiqizwe ligobe futhi liguquguquke ngokuthuthukisa ukuguquguquka okuphelele.I-UPVC ayinawo amapulasitiki, futhi i-UPVC ayiqukethe i-BPA ye-PVC.
Ama-Plasticizer akhiwa lapho ama-asidi notshwala kusabela ngamakhemikhali.Ama-asidi asetshenziswa kakhulu afaka i-phthalic anhydride ne-adipic acid.Kunezinhlobo ezahlukene zotshwala, futhi inhlanganisela yama-acids nama-alcohols asetshenziselwa ukunquma izinhlobo zama-ester nama-plasticizers angenziwa.
I-PVC isetshenziswa kabanzi ukufaka esikhundleni samapayipi ensimbi amadala, amapayipi kasimende, njll. ezinhlelweni zokuchelela, amapayipi amanzi angcolile kanye nezinhlelo zamachibi.Ukusebenzisa i-glue kungasetshenziswa ukuyilungisa, okulungele ukwakhiwa.I-UPVC yaziwa ngokumelana kwayo namakhemikhali.Kuyasiza futhi ukuqinisekisa ukugeleza kwamanzi okwanele ngenxa yezindonga zangaphakathi ezibushelelezi.Inzima kune-PVC, kodwa ibhekwa njengenamandla, okwenza imelane nezingcindezi ezihlukahlukene zokusebenza namazinga okushisa.
Ukwelashwa
Zombili izinhlobo zamapayipi ziphathwa cishe ngendlela efanayo.Amathuluzi athile wamandla okusika i-PVC nama-plastic cutting hacksaw blades afaneleka kuzo zombili izinhlobo zamapayipi.Umehluko phakathi kwakho kokubili uhlobene nokuguquguquka kosayizi.Isibonelo, uma i-PVC inganqunywanga kahle, ukuguquguquka kwayo kuyivumela ukuthi ihlale ilingana kahle.Kodwa-ke, nge-UPVC, kufanele isikwe kuzilinganiso ezinembile noma ngeke isebenze ekusetshenzisweni okuhlosiwe.Lokhu kungenxa yokuthi iqinile futhi ayikwazi ukunwebeka kancane njenge-PVC.
Ekwakhiweni, zombili izinhlobo zepulasitiki zisetshenziselwa ukwenza uhla lwamapayipi.Isibonelo, amapayipi amakhulu e-PVC angasetshenziswa ukusiza ukuhambisa amanzi angaphuzwa.Okunye ukusetshenziswa okuvamile izintambo, lapho iningi le-PVC lihlinzeka ngokufakwa okwengeziwe.
Ekwakhiweni, i-UPVC iyindawo ekahle yokhuni ezimweni eziningi.Isibonelo, ingasetshenziswa ukwenza amafreyimu amafasitela ahlala isikhathi eside futhi akwazi ukumelana nezakhi kangcono kunokhuni.I-PVC evamile ayikwazi ukusetshenziselwa ukudala amafreyimu ewindi.Lokhu kungenxa yokuthi i-UPVC ayiboli, kodwa i-PVC evamile iyabola.I-PVC evamile ayimelani nesikhumba njenge-UPVC.Labo abasebenza esakhiweni bangasebenzisa le nto esikhundleni sensimbi yokukhipha amanzi esindayo kanye namapayipi
