I-Polyvinyl chloride (PVC), i-thermoplastic ethandwa kakhulu, inobuthakathaka obungafihliwe kangako: ithambekele ekuwohlokeni ngesikhathi sokucubungula nokusetshenziswa. Kodwa ungesabi! NgenaIziqinisi ze-PVC, amaqhawe angadunyiswanga ezweni lamapulasitiki. Lezi zithasiselo ziyisihluthulelo sokulawula isimo sengqondo se-PVC, ukucindezela ngempumelelo ukuwohloka nokwandisa isikhathi sayo sokuphila. Kulesi sihloko sebhulogi, singena shí ezweni elithakazelisayo lama-PVC stabilizers, sihlola izinhlobo zawo, izindlela zokusebenza, izindawo zokufaka isicelo, kanye nezitayela ezijabulisayo ezakha ikusasa lawo.
I-PVC akuyona nje enye ipulasitiki; iyisisetshenziswa esinamandla esiguquguqukayo. Ngezakhiwo zayo ezinhle kakhulu zemishini, ukumelana namakhemikhali okumangalisayo, ukuvikela ugesi okuphezulu, kanye nentengo engabizi, i-PVC ithole indlela yayo ezimbonini eziningi, kusukela ekwakheni nasekupakisheni kuya ekukhiqizeni ucingo kanye nekhebula kanye namadivayisi ezokwelapha. Kodwa-ke, kukhona ukubamba. Isakhiwo sama-molecule e-PVC siqukethe ama-athomu e-chlorine angazinzile, lapho evezwa ekushiseni, ekukhanyeni, noma emoyeni, abangela ukusabela kweketanga okwaziwa ngokuthi i-dehydrochlorination. Lokhu kusabela kubangela ukuthi izinto zishintshe umbala, zilahlekelwe ukusebenza kwazo, futhi ekugcineni zingabi usizo. Yingakho ukwengeza iziqinisi ngesikhathi sokucubungula nokusebenzisa i-PVC kungeyona nje inketho—kuyisidingo.
Iziqinisi ze-PVC zingahlukaniswa ngezigaba ngokusekelwe ekwakhekeni kwazo kwamakhemikhali zibe yizigaba eziningana.izinhlobo:
Iziqinisi Zikasawoti Eziholayo:Laba babengamaphayona emdlalweni we-PVC stabilizer, benokuqina kokushisa okuhle kakhulu kanye nokusebenza kahle kwezindleko. Kodwa-ke, ngenxa yokukhathazeka kwabo ngobuthi, baye bancishiswa kancane kancane eminyakeni yamuva.
Iziqinisi Zensipho Yensimbi:Leli qembu lihlanganisa ezidumile njengeziqinisi ze-calcium-zinc kanye ne-barium-zinc. Zinikeza ukuzinza okuhle kokushisa kanye nokuthambisa, okwenza zibe ngesinye seziqinisi ze-PVC ezisetshenziswa kakhulu namuhla.
Iziqinisi ze-Organotin:Njengoba zidumile ngokuqina kwazo kokushisa okuvelele kanye nokubonakala kalula, iziqinisi ze-organotin ziza nentengo ephezulu. Zisetshenziswa kakhulu emikhiqizweni ye-PVC esobala.
Iziqinisi Zomhlaba Ezingavamile:Njengabantwana abasha kule ndawo, lezi ziqinisi ezinobungani nemvelo zinikeza ukuzinza okukhulu kokushisa, azinabo ubuthi, futhi zinikeza ukucaca okuhle. Kodwa, njengeziqinisi ze-organotin, ziza ngezindleko eziphakeme kakhulu.
Iziqinisi Ezisizayo Zemvelo:Zodwa, lezi azinazo izakhiwo zokuzinza. Kodwa uma zihlanganiswa nezinye izinto zokuzinza, zisebenza ngomlingo wazo, zithuthukisa ukusebenza kahle kokuzinza. Izibonelo zifaka phakathi ama-phosphite nama-epoxide.
Ngakho-ke, lezi ziqinisi zisebenza kanjani ngempela umlingo wazo? Nazi izindlela eziyinhloko:
Ukumuncwa kwe-HCl:Izinzisa zisabela ne-hydrogen chloride (HCl) ekhiqizwa ngesikhathi sokuwohloka kwe-PVC, okumisa umphumela wayo wokuzivuselela.
Ukufakwa esikhundleni kwe-Chlorine Atom Okungazinzile:Ama-ion ensimbi kuma-stabilizer athatha indawo yama-athomu e-chlorine angazinzile ku-molecule ye-PVC, okwenza kube ngcono ekuzinzeni kokushisa.
Isenzo Sokulwa No ...Ezinye izinto eziqinisayo zinezakhiwo zokulwa ne-antioxidant, ezisiza ekuvimbeleni ukuwohloka kwe-PVC.
Iziqinisi ze-PVC zikhona yonke indawo ekuphileni kwethu kwansuku zonke, zidlala indima ebalulekile kuma-PVC ahlukahlukeneimikhiqizo:
Imikhiqizo ye-PVC eqinile:Cabanga ngamapayipi, amaphrofayili, namashidi. Kulokhu, kuvame ukusetshenziswa iziqinisi zosawoti we-lead, iziqinisi zomshanelo wensimbi, kanye neziqinisi zomhlabathi ongavamile.
Imikhiqizo ye-PVC eguquguqukayo:Izinto ezifana nezintambo, izintambo, isikhumba sokwenziwa, namafilimu zithembele kakhulu ezintweni eziqinisa insipho yensimbi kanye nezinto eziqinisa i-organotin.
Imikhiqizo ye-PVC esobala:Kungakhathaliseki ukuthi amabhodlela noma amashidi, ama-organotin stabilizers ayindlela engcono kakhulu yokuqinisekisa ukucaca.
Njengoba umhlaba uqaphela kakhulu imvelo futhi ubuchwepheshe buqhubeka nokukhula, ikusasa lama-PVC stabilizers liyathuthuka ngendlela ejabulisayoizindlela.
Ukuya Ohlaza:Ukugxila ekuthuthukiseni izinto eziqinisa imvelo ezingenabungozi, ezingenabungozi, nezibolayo, njenge-calcium-zinc kanye neziqinisa imvelo ezingavamile.
Ukuthuthukisa Ukusebenza Kahle:Kukhona ukusunduza ukudala iziqinisi ezisebenza kangcono ngokuncane, zinciphise izindleko ngenkathi zigcina ukusebenza okuphezulu.
Imisebenzi Yokuphindaphinda:Lindela ukubona izinto eziqinisayo ezenza imisebenzi engaphezu kowodwa, njengokuhlinzeka kokubili ukuzinza kokushisa kanye nokuthambisa noma ngisho nezakhiwo ezivimbela ukuguquguquka.
Amandla Okuhlanganiswa:Ukuxuba izinhlobo ezahlukene zeziqinisi ukudala imiphumela yokusebenzisana nokufeza imiphumela engcono kakhulu yokuzinzisa sekuba umkhuba.
Kafushane nje, iziqinisi ze-PVC zingabaqaphi abathule be-PVC, ziqinisekisa ukuthi isebenza kahle kakhulu futhi ihlala isikhathi eside. Ngemithethonqubo eqinile yezemvelo kanye nentuthuko eqhubekayo yezobuchwepheshe, ikusasa lingelabaqinisi be-PVC abanobungani nemvelo, abaphumelelayo, abasebenza ngezindlela eziningi, futhi abahlanganisiwe. Hlala uqaphile ngalezi zinto ezintsha—zizoguqula umhlaba wepulasitiki!
