Izixazululo Zethangi Lamanzi le-PVC Zisiza Ukuthuthukiswa Kwemboni Ngempumelelo
Ezinhlelweni zesimanje zezimboni nezindawo zokuhlala, ukukhethwa kwempahla yokugcina amanzi kuthinta ngokuqondile ukuzinza nokuphepha kwesistimu. Amathangi amanzi e-PVC, anokumelana nokugqwala kwawo, idizayini engasindi, ukuqina, nezindleko ezithengekayo, asephenduke isixazululo esithandwayo ezimeni eziningi. Kodwa-ke, idizayini yesayensi, ukufakwa okufanele, nokugcinwa okusebenzayo kwamathangi amanzi e-PVC kusalokhu kuyizinkathazo ezibalulekile embonini. Lesi sihloko sihlola izixazululo ezibanzi zamathangi amanzi e-PVC ngokwemibono emithathu: izakhiwo zezinto ezibonakalayo, izimo zohlelo lokusebenza, namasu okuthuthukisa.
I-PVC (i-polyvinyl chloride) inokumelana namakhemikhali okuhle kakhulu, imelana nokugqwala okuvela ezinhlobonhlobo zoketshezi olune-asidi nolwe-alkali. Ilungele ukugcina uketshezi emikhakheni yokuchelela ngamakhemikhali, ezemvelo, kanye nezolimo. Ngaphezu kwalokho, isisindo sayo sicishe sibe{2}}kusodwa kuphela kwesihlanu samathangi ensimbi, okwehlisa kakhulu ubunzima bokuhamba nokufaka. Ifaneleka ngokukhethekile{4}izinto zokusebenza ezingasindi ezifana namathangi asophahleni nokugcinwa kwamanzi kwesikhashana. Ngaphezu kwalokho, ingaphakathi elibushelelezi lamathangi amanzi e-PVC limelana nokukhula kwebhaktheriya, ukuhlangabezana nezindinganiso zokuhlanzeka kwamanzi okuphuza kanye nokuthola ukusetshenziswa okubanzi ezinhlelweni zokuhlinzeka ngamanzi zokuhlala.
Izixazululo zethangi lamanzi le-PVC zidinga imiklamo ehlukene yezindawo ezahlukene zokusetshenziswa. Isibonelo, ezifundeni{1}}zezinga lokushisa eliphezulu, i-PVC elungisiwe enokumelana nokushisa okuthuthukisiwe iyadingeka ukuze kuvinjelwe ukonakala okubangelwa ukuchayeka isikhathi eside elangeni. Ezindaweni zezimboni ezinama-asidi aqinile nama-alkali, amaphaneli aminyene noma izimbotshana ezikhethekile ziyadingeka ukuze kuthuthukiswe ukumelana nokugqwala. Ukufakwa nakho kubalulekile; ukuqina kwesisekelo, amandla esakhiwo sokusekela, kanye nokucinana kokuxhunywa kwamapayipi konke kuthinta ngokuqondile ukuphila kwethangi lamanzi. Ukuxhuma okuvumelana nezimo kuyatuswa, futhi izinyathelo zokuvimbela ukuvuza emalungeni kufanele zihlolwe njalo.
Ukuhlanza njalo nokubulala amagciwane kuyisihluthulelo sokuqinisekisa ikhwalithi yamanzi. Emathangeni agcina uketshezi oluthambekele ekubeni nenzika isikhathi eside, amathuluzi anyakazayo noma ama-valve okukhipha amanzi angengezwa ukunciphisa ukunqwabelana kwenhlabathi. Ngaphezu kwalokho, abasebenzisi kufanele basungule isistimu yokuhlola evamile, egxile ekuqhekekeni kwamajoyinti ephaneli kanye nokuwohloka kongqimba lokuvikela lwe-UV, futhi basebenzise ukulungisa noma ukushintshwa ngokushesha.
Ngokuthuthuka kwesayensi yezinto zokwakha, amathangi amanzi e-PVC azoqhubeka nokuguqukela esisindweni esilula kanye nobuchwepheshe obukhaliphile. Abadlali bemboni badinga ukuqhubeka nokuthuthukisa izixazululo zedizayini futhi banikeze izinsiza ezenziwe ngokwezifiso ezihambisana nezidingo zabasebenzisi, ngaleyo ndlela bakhuthaze ukusebenza kahle, ukuphepha, kanye nentuthuko eqhubekayo yezinto zokusebenza zokugcina amanzi.
