Yintoni umahluko phakathi kwemibhobho ye-UPVC kunye ne-PVC

Yintoni umahluko phakathi kwePVC kunye neUPVC?

Ngelixa zombini ezi ntlobo zisetyenziswa ngokubanzi, kukho umahluko phakathi kwe-UPVC kunye nePVC.Ngapha koko, kukho iipropathi ezininzi ezizikhuselayo, makhe sijonge ukuba zenziwe kwaye zisetyenziswa njani.
inkqubo yokuvelisa

Kwiimeko ezininzi, zombini iindidi zenziwe kwi-polymer polyvinyl chloride.Nangona kunjalo, abavelisi abenza le mibhobho banokudibanisa iiplastiki ezahlukeneyo kumxube ukwenza kube lula ukusebenza nazo.Xa ezi plasticizers zingasetyenziswa, umbhobho ubizwa ngokuba UPVC.

Iimpawu

Umahluko phakathi kwemibhobho ye-UPVC kunye ne-PVC iphinda ifikelele kwiipropati.IiPlastiki zisetyenziswa kwimibhobho yePVC, kunye neephthalates zezona zixhaphakileyo.Le kunye nezinye iiplasticizers azinavumba kwaye azinabala.Xa zifakwe kwi-PVC, zenza umbhobho oveliswe ngakumbi kwaye uguquguquke ngokunyusa ukuguquguquka ngokubanzi.I-UPVC ayinazo iiplastiki, kwaye i-UPVC ayinayo i-BPA ye-PVC.
Iiplastiki zeplastiki zenziwe xa i-acids kunye nee-alcohols zisabela ngokwekhemikhali.Iiasidi ezisetyenziswa ngokuqhelekileyo ziquka i-phthalic anhydride kunye ne-adipic acid.Kukho iintlobo ezahlukeneyo zotywala, kunye neendibaniselwano ze-acids kunye ne-alcohols zisetyenziselwa ukumisela iintlobo ze-esters kunye ne-plasticizers ezinokuthi zenziwe.

I-PVC isetyenziswa ngokubanzi ukutshintsha imibhobho yentsimbi emidala, imibhobho yesamente, njl.njl. kwiinkqubo zokunkcenkceshela, imibhobho yamanzi amdaka kunye neenkqubo zamachibi.Ukusebenzisa i-glue ingasetyenziselwa ukuyilungisa, ekulungele ukwakhiwa.I-UPVC yaziwa ngokumelana neekhemikhali.Kwakhona kunceda ukuqinisekisa ukuhamba kwamanzi okwaneleyo ngenxa yeendonga zangaphakathi ezigudileyo.Inzima kunePVC, kodwa ithathwa njengenamandla, iyenza ikwazi ukumelana noxinzelelo kunye nobushushu bokusebenza.

Unyango

Zombini iintlobo zemibhobho ziphathwa ngokulinganayo ngokufanayo.Izixhobo ezithile zamandla zokusika i-PVC kunye neeplastiki zokusika i-hacksaw blades zifanelekile kuzo zombini iintlobo zemibhobho.Umahluko phakathi kwezi zibini unento yokwenza nokuguquguquka kobungakanani.Umzekelo, ukuba iPVC ayinqunyulwanga ngokuchanekileyo, ukuguquguquka kwayo kuyayivumela ukuba ihlale kakuhle.Nangona kunjalo, nge-UPVC, kufuneka isikwe kwimilinganiselo echanekileyo okanye ayiyi kusebenza kwisicelo esicetywayo.Oku kungenxa yokuba iqinile kwaye ayinako ukwelula kancinci njengePVC.

Ekwakhiweni, zombini iintlobo zeplastiki zisetyenziselwa ukwenza uluhlu lwemibhobho.Umzekelo, imibhobho emikhulu yePVC ingasetyenziselwa ukunceda ukuhambisa amanzi angaselwayo.Olunye usebenziso oluqhelekileyo lwenziwa kwiintambo, apho uninzi lwePVC lubonelela ngokufakwa okongeziweyo.
Kulwakhiwo, i-UPVC iyindawo efanelekileyo yomthi kwiimeko ezininzi.Umzekelo, ingasetyenziselwa ukwenza iifreyimu zefestile ezomeleleyo kwaye ezinokumelana nezinto ezingcono kunomthi.I-PVC eqhelekileyo ayinakusetyenziswa ukwenza izakhelo zefestile.Oku kungenxa yokuba i-UPVC ayiboli, kodwa iPVC eqhelekileyo iyabola.I-PVC eqhelekileyo ayinyangeki njengesikhumba njenge-UPVC.Abo basebenza kulwakhiwo banokusebenzisa le mathiriyeli endaweni yentsimbi etyhidiweyo yokuhambisa amanzi obunzima kunye nemibhobho yamanzi
