I-PVC vs. Iplastiki eqhelekileyo: Ukuqonda umahluko

Xa kufikwa kwimibhobho yamanzi kunye nokwakhiwa, amagama athi PVC, UPVC, kunye neplastiki ahlala esetyenziswa ngokutshintshanayo. Nangona kunjalo, kukho umahluko ocacileyo phakathi kwezi zixhobo ezibalulekileyo ukuba uziqonde, ngakumbi xa kufikwa kwi-valve fittings. Kweli nqaku, siza kuphonononga umahluko phakathi kwePVC kunye neplastiki eqhelekileyo, kunye nokuba ezi zintlukwano zichaphazela njani ukukhethwa kofakelo lwevalvu kwizicelo ezahlukeneyo.

I-PVC, emele i-polyvinyl chloride, luhlobo lweplastiki olusetyenziswa kakhulu kushishino lokwakha. Iyaziwa ngokuhlala kwayo, ukumelana neekhemikhali, kunye nokuguquguquka. I-UPVC, okanye i-polyvinyl chloride engafakwanga plastiki, luhlobo oluthile lwePVC oluqina ngakumbi kwaye luxhathisa ukubola kweekhemikhali. Zombini i-PVC kunye ne-UPVC zisetyenziswa ngokuqhelekileyo ekuveliseni izixhobo zevalve ngenxa yokukwazi ukujamelana noxinzelelo oluphezulu kunye neendawo ezinzima.

Ngakolunye uhlangothi, iplastiki eqhelekileyo, edla ngokubizwa ngokuba yi "plastiki," ligama elibanzi elibandakanya uluhlu olubanzi lwee-synthetic okanye i-semi-synthetic organic compounds. Ngokungafaniyo nePVC kunye ne-UPVC, iplastiki yesiqhelo inokwahluka kakhulu ngokweempawu zayo, kubandakanya amandla, ukuguquguquka, kunye nokumelana nemichiza kunye nobushushu.

Omnye umahluko ophambili phakathi kwePVC kunye neplastiki eqhelekileyo ilele ekubunjweni kwayo. I-PVC yi-thermoplastic, ethetha ukuba inokufudunyezwa kwaye ibunjwe kwiimilo ezahlukeneyo, iyenze ilungele ukwenziwa kofakelo lwevalvu ngoyilo oluntsonkothileyo. Ngokwahlukileyo, iplastiki eqhelekileyo inokuba yi-thermoplastic okanye i-thermosetting, kwaye le yokugqibela iqinile kwaye ingabunjwa kangako.

Omnye umahluko obalulekileyo kukwenziwa kweekhemikhali zePVC kunye neplastiki eqhelekileyo. I-PVC ngokwendalo iyamelana nelangatye kwaye inokumelana okuphezulu nemichiza, iyenza ilungele usetyenziso apho ukuvezwa kwezinto ezidlayo kuyinkxalabo. Iplastiki eqhelekileyo, kuxhomekeke ekubunjweni kwayo, ayinakunika inqanaba elifanayo lokumelana neekhemikhali kunye nokunciphisa umlilo njengePVC.

Xa kuziwa ekukhetheni izixhobo zevalve, ukhetho phakathi kwePVC kunye neplastiki eqhelekileyo kuxhomekeke kwiimfuno ezithile zesicelo. Umzekelo, kwiinkqubo zemibhobho yemibhobho apho ukuxhathisa kulwelo olubolayo kubalulekile, i-PVC okanye i-UPVC ifakela iivalvu zihlala zikhethwa ngenxa yokuxhathisa kwazo iikhemikhali kunye nokuqina. Ngokwahlukileyo, izifakelo zevalvu zeplastiki eziqhelekileyo zinokufaneleka kwizicelo zoxinzelelo oluphantsi apho iindleko kunye nokuguquguquka ziyingqwalasela ephambili.

Ngokubhekiselele kwimpembelelo yokusingqongileyo, iPVC kunye neeplastiki eziqhelekileyo nazo ziyahluka. I-PVC yaziwa ngokuba lukhetho oluzinzileyo xa kuthelekiswa nolunye uhlobo lweplastiki eqhelekileyo, njengoko inokuphinda isetyenziswe kwakhona kwizicelo ezahlukeneyo. Ukongeza, i-PVC inobomi obude, inciphisa isidingo sokutshintshwa rhoqo kunye nokunciphisa inkunkuma.

Ukuqukumbela, ngelixa zombini iPVC kunye neplastiki eqhelekileyo zisetyenziswa ekuveliseni izifakelo zevalvu, kukho umahluko omkhulu ekubunjweni kwazo, iipropathi, kunye nokufaneleka kwezicelo ezahlukeneyo. Ukuqonda le mahluko kubalulekile ukwenza izigqibo ezizizo xa ukhetha izifakelo zevalvu ukulungiselela imibhobho yamanzi kunye neeprojekthi zokwakha. Ngokuqwalasela izinto ezinjengokumelana neekhemikhali, ukuguquguquka, kunye nefuthe lokusingqongileyo, iingcali zinokukhetha ezona zinto zifanelekileyo kwiimfuno zabo ezithile, ziqinisekisa ixesha elide kunye nokuthembeka kweenkqubo zabo.
