Cabanga ngalokhu: Ungena esitolo sefenisha esidumile futhi udonseleka ngokushesha kusofa lesikhumba lokwenziwa elinobukhazikhazi nelinesitayela. Umbala walo ocebile kanye nokuthungwa okubushelelezi kubukeka sengathi kungamelana novivinyo lwesikhathi. Noma mhlawumbe uthenga isikhwama esisha sesandla, futhi inketho yesikhumba somgunyathi idonsa amehlo akho ngokuqedwa kwayo okukhazimulayo kanye nomuzwa wokunethezeka. Kuthiwani uma ngikutshela ukuthi ngemuva kokubukeka okuhle nokuqina kwale mikhiqizo yesikhumba sokwenziwa kukhona iqhawe elifihliwe—iziqinisi ze-PVC? Ake siqale uhambo lokuthola ukuthi lezi zithasiselo zisebenza kanjani umlingo wazo ezweni lesikhumba sokwenziwa, sihlola imisebenzi yazo, ukusetshenziswa kwazo emhlabeni wangempela, kanye nomthelela wazo emikhiqizweni esiyithandayo.
Indima Ebalulekile Ka-Iziqinisi ze-PVC esikhumbeni sokwenziwa
Isikhumba sokwenziwa, esivame ukwenziwa nge-polyvinyl chloride (PVC), sesibe ukukhetha okuthandwayo embonini yemfashini nefenisha ngenxa yokungabizi kakhulu, ukuguquguquka, kanye nekhono lokulingisa ukubukeka nomuzwa wesikhumba sangempela. Kodwa-ke, i-PVC inesithende se-Achilles—isengozini enkulu yokuwohloka uma ivezwa ekushiseni, ekukhanyeni, nasemoyeni. Ngaphandle kokuvikelwa okufanele, imikhiqizo yesikhumba sokwenziwa ingasheshe iphele, iqhekeke, futhi ilahlekelwe ukuguquguquka kwayo, ishintshe ibe yinto ebizayo ibe ukuthenga okudumazayo.
Yilapho-keIziqinisi ze-PVCZiyangena. Lezi zithasiselo zisebenza njengabavikeli, zinciphisa imiphumela eyingozi ebangela ukuwohloka kwe-PVC. Zimunca i-hydrochloric acid (HCl) ekhishwa ngesikhathi senqubo yokuwohloka, zithathe indawo yama-athomu e-chlorine angazinzile ku-molecule ye-PVC, futhi zinikeze isivikelo se-antioxidant. Ngokwenza kanjalo,Iziqinisi zokushisa ze-PVCqinisekisa ukuthi isikhumba sokwenziwa sigcina ukubukeka kwaso okuhle, ubuqotho besakhiwo, kanye nokusebenza kwaso isikhathi eside, okwenza kube ukukhetha okuthembekile kwezinhlelo zokusebenza eziningi ezahlukene.
Izinhlobo Zeziqinisi Ze-PVC Nezicelo Zazo Ezinethonya Esikhumbeni Sokwenziwa
Izinzinzisi zeCalcium – Zinc: Ompetha Abanobungane Nemvelo
Esikhathini lapho ukuqaphela imvelo kuphambili,iziqinisi ze-calcium - zincsezivele zaduma embonini yesikhumba sokwenziwa. Lezi ziqinisi azinabo ubuthi, okwenza zifaneleke kahle emikhiqizweni ethintana ngqo nesikhumba, njengezingubo, izicathulo kanye nezikhwama zesandla.
Ngokwesibonelo, cabanga ngomkhiqizo wemfashini ozinzile owaziwayo osanda kwethula iqoqo lamajakethi esikhumba e-vegan. Ngokusebenzisa izithambisi ze-calcium - zinc ekukhiqizeni isikhumba sabo sokwenziwa esisekelwe ku-PVC, abazange bahlangabezane nesidingo esikhulayo semfashini enobungani nemvelo kodwa futhi baletha imikhiqizo enekhwalithi ephezulu. Amajakethi agcina imibala yawo egqamile kanye nokuthungwa okuthambile ngisho nangemva kokuguguleka nokuwashwa kaningi. Izakhiwo ezinhle kakhulu zokushisa - ukuzinza kwezithambisi zazibalulekile ngesikhathi senqubo yokukhiqiza, okuvumela isikhumba ukuba sibunjwe futhi sibunjwe ngaphandle kokuwohloka. Ngenxa yalokho, amakhasimende omkhiqizo akwazi ukujabulela amajakethi anesitayela, ahlala isikhathi eside angayekethisi ekusimameni.
Izithambisi ze-Organotin: Isihluthulelo se-Premium - Isikhumba Sokwenziwa Esisezingeni Eliphezulu
Uma kukhulunywa ngokudala isikhumba sokwenziwa esisezingeni eliphezulu esinokukhanya okuphezulu kanye nokumelana nokushisa, iziqinisi ze-organotin ziyinketho engcono kakhulu. Lezi ziqinisi zivame ukusetshenziswa ekukhiqizweni kwemikhiqizo yesikhumba yokwenziwa esezingeni eliphezulu, njengempahla yokulala efenisha esezingeni eliphezulu kanye nezikhwama zezandla eziklanyiwe.
Umkhiqizi wefenisha yokunethezeka, isibonelo, wayefuna ukudala uhla lwamasofa esikhumba okwenziwa angancintisana nekhwalithi yesikhumba sangempela. Ngokufakaiziqinisi ze-organotinkwifomula yabo ye-PVC, bathole izinga lokucaca kanye nokushelela okwakumangalisa ngempela. Osofa babenesiphetho esihle nesicwebezelayo esabenza babukeke futhi bazizwe njengesikhumba sangempela. Ngaphezu kwalokho, ukuzinza kokushisa okuthuthukisiwe okunikezwa yiziqinisi ze-organotin kwaqinisekisa ukuthi isikhumba singamelana nobunzima bokusetshenziswa kwansuku zonke, okuhlanganisa ukuchayeka elangeni kanye nokushintsha kwezinga lokushisa, ngaphandle kokuphela noma ukuqhekeka. Lokhu kwenza osofa bangabi nje kuphela isengezo esihle kunoma yiliphi ikhaya kodwa futhi babe utshalomali oluhlala isikhathi eside kumakhasimende.
Indlela Izinzisa ze-PVC Ezibumba Ngayo Ukusebenza Kwesikhumba Sokwenziwa
Ukukhetha i-PVC stabilizer kunomthelela omkhulu ekusebenzeni kwesikhumba sokwenziwa. Ngale kokuvimbela ukuwohloka,iziqinisiingathonya izici ezahlukahlukene zezinto, njengokuguquguquka kwazo, ukungaguquguquki kombala, kanye nokumelana namakhemikhali.
Isibonelo, ekukhiqizweni kwesikhumba sokwenziwa esithambile, esinwebekayo sezingubo zezemidlalo, inhlanganisela efanele yeziqinisi kanye nezipulasitiki ingadala into ehamba nomzimba, inikeze induduzo kanye nenkululeko yokuhamba. Ngesikhathi esifanayo, iziqinisi ziqinisekisa ukuthi isikhumba asilahlekelwa ukuma kwaso noma umbala waso ngokuhamba kwesikhathi, ngisho nokusetshenziswa njalo nokuwashwa. Endabeni yesikhumba sokwenziwa esisetshenziswa efenisha yangaphandle, iziqinisi ezinokumelana okuthuthukisiwe kwe-UV zingavikela impahla emisebeni yelanga eyingozi, zivimbele ukufiphala nokuqhekeka futhi zandise isikhathi sokuphila sefenisha.
Ikusasa Lama-PVC Stabilizers Esikhumbeni Sokwenziwa
Njengoba isidingo sesikhumba sokwenziwa siqhubeka sikhula, nesidingo sezixazululo ezintsha ze-PVC stabilizer. Ikusasa lomkhakha cishe lizobunjwa yizitayela eziningana. Enye yezindawo ezibalulekile okuzogxilwa kuzo ukuthuthukiswa kwezithambisi-ndlela eziningi ezihlinzeka hhayi nje kuphela ngokuvikelwa kokushisa nokukhanya okuyisisekelo kodwa futhi nezinzuzo ezengeziwe njengezakhiwo zokulwa namagciwane, amakhono okuziphilisa, noma ukuphefumulela okuthuthukisiwe.
Esinye isimo ukusetshenziswa okwandayo kwe-iziqinisi ezisekelwe ku-bio nezisimemeNjengoba abathengi beqaphela kakhulu imvelo, kunemakethe ekhulayo yemikhiqizo yesikhumba sokwenziwa engeyona nje kuphela enesitayela futhi ehlala isikhathi eside kodwa futhi eyenziwe ngezinto ezinobungani nemvelo. Abakhiqizi bahlola izindlela zokusebenzisa izithako zemvelo kanye nezinsiza ezivuselelekayo ekukhiqizeni izinto eziqinisa imvelo, okunciphisa umthelela wemvelo wokukhiqizwa kwesikhumba sokwenziwa.
