Ukukhiqiza i-PVC kuhlale kubhekene nezinkinga ezimbili zekhwalithi eziphica onjiniyela bokukhiqiza kanye nabakhiqizi: ukushintsha kombala komkhiqizo okungalindelekile kanye nokuna kwezulu. Izimboni eziningi zichitha amahora amaningi zilungisa amazinga okushisa okucubungula, zishintsha izilinganiso zefomula, futhi zishintsha amaqoqo ezinto zokusetshenziswa, kodwa ukuphuzi, izindawo ezimnyama, kanye nokuna kwempuphu emhlophe kusaqhubeka emikhiqizweni ye-PVC esiqediwe. Lezi ziphambeko azigcini nje ngokonakalisa ukubukeka komkhiqizo kanye nokucaca kodwa futhi ziholela ekungahambelani kweqoqo, ukwanda kwamanani emfucumfucu, kanye namathuba ebhizinisi alahlekile ama-oda okwenza ngokwezifiso aphezulu.
Amaqembu amaningi okukhiqiza awayinaki imbangela eyinhloko: ukulandelela ukungcola ezingeni eliphansiIziqinisi ze-PVCNakuba iziqinisi ezijwayelekile zinikeza isivikelo esiyisisekelo sokushisa ngesikhathi sokukhipha kanye nokubumba, ukungcola okusele kubangela ukusabela okungabonakali kokuwohloka kwe-catalytic okulimaza izakhiwo zama-molecule e-PVC ngokuhamba kwesikhathi.Iziqinisi ze-PVC ezihlanzekile kakhulu, okuhlanganisa izinhlobo ze-CaZn, i-BaZn, kanye ne-methyl tin ze-premium, zixazulula lezi zinkinga eziyisisekelo ngokunciphisa okuqukethwe kokungcola, ukuzinzisa ukucubungula ukushisa, kanye nokugcina ukuhambisana kombala isikhathi eside kuzo zonke izinhlobo zemikhiqizo ye-PVC.
Isixhumanisi Esifihliwe Phakathi Kokungcola Kwe-Stabilizer Nokuwohloka Kwekhwalithi Ye-PVC
I-Polyvinyl chloride (PVC) ayinakho ukuzinza kokushisa okungokwemvelo. Ngaphansi kwezimo zokucubungula izinga lokushisa eliphezulu ezidingekayo ukuze kufakwe futhi kukhishwe, i-PVC engashintshiwe idlula ekuqhekekeni kwe-molecular chain kanye nokubola kokushisa, okubangela ngokwemvelo ukufiphala nokuphuzi. Iziqinisi zokushisa ziyangezwa ukuze kuncishiswe izisusa zokubola futhi kuvale ukuzinza komkhiqizo ngesikhathi sokukhiqiza kanye nokuphila kwesikhathi eside kwenkonzo.
Umehluko oyinhloko phakathi kweziqinisi ezijwayelekile nezihlanzekile kakhulu usezintweni ezisele. Iziqinisi ezivamile ezishibhile ziqukethe ama-free acid angasuswanga, izinsalela zensimbi esindayo, kanye nezinhlayiya zokungcola okungokwemvelo. Lezi zingcolisi ezincane kakhulu azibangeli umonakalo obonakalayo ngokushesha ngemva kokukhiqizwa. Esikhundleni salokho, zisebenza njengezikhuthazi zomsebenzi ophezulu ezisheshisa njalo ukuwohloka kokushisa kwe-PVC ngesikhathi sokucubungula nokusetshenziswa kwansuku zonke.
Lokhu kusabela okubangela ukusheshisa kuveza izinto ezintathu ezijwayelekile ezinephutha ekukhiqizweni okukhulu. Okokuqala, ukushintsha kombala okuqhubekayo, okuhlanganisa ukuphuzi okuphelele kanye nokuphambuka kombala wendawo phakathi kwamaqoqo okukhiqiza. Okwesibili, imvula ebusweni, lapho izinhlanganisela zokungcola ezingaphenduliwe zithuthela ngaphandle ukuze zakhe i-white powder noma amafilimu afiphele, zibhubhise ukukhanya kwendawo kanye nokucaca. Okwesithathu, ukusheshisa ukwehluleka kokuguga, okwenza imikhiqizo ye-PVC ithambekele ekuqhekekeni nasekufeni kombala ngaphansi kokukhanya kwangaphandle kanye nezindawo ezinomswakama ophezulu. Ngokungafani namaphutha okucubungula alungisekayo, la maphutha avela ekungcoleni ayaqhubeka futhi awakwazi ukulungiswa ngokwelashwa kwangemva kokukhiqiza.

Ngokumelana nokushisa okuhle kakhulu kanye nokusebenza okulwa nokuguga, zicindezela ngempumelelo ukuwohloka kwe-catalytic okubangelwa ukungcola okusele ngaphansi kwemisebe enamandla ye-ultraviolet kanye nezindawo zokushisa okuphezulu. Abakhiqizi basebenzisa kakhulu iziqinisi ze-BaZn ezihlanzekile kakhulu kumaphrofayili e-PVC angaphandle, amaphaneli odonga, kanye nezinto zombhobho eziveziwe, ukuxazulula izinkinga zesikhathi eside zokuguqulwa komkhiqizo wangaphandle kanye nokushintsha kombala.
• Isiqinisi Se-Methyl Tin Esihlanzekile Kakhulu
Iziqinisi ze-Methyl tinzimelela izinga eliphezulu lokuhlanzeka phakathi kweziqinisi ze-PVC ezivamile, cishe zingenazo nhlobo ukungcola okubonakalayo. Ziqeda ngokuphelele ukuwohloka kwezinga lama-molecule, ziletha ukucaca okuvelele kanye nokugcinwa kombala. Lokhu kuzenza zibe ukukhetha okukhethekile kwemikhiqizo ye-PVC esobala ephezulu, kufaka phakathi amapayipi abonakalayo, amafilimu okupakisha, kanye nezinto ze-PVC zezinga lokukhanya. Akukho ukufiphala, ukuphuzi, noma imvula okwenzekayo ngisho nangemva kokugcinwa isikhathi eside nokusetshenziswa ngamandla aphezulu, okuqinisekisa ukubukeka komkhiqizo osezingeni eliphezulu njalo.
Amathiphu Okukhetha Izithambisi Ezisebenzayo Zabakhiqizi be-PVC
Ukuqondanisa iziqinisi ezihlanzekile kakhulu nezidingo zokukhiqiza kuyindlela engabizi kakhulu yokunciphisa amazinga anephutha nokuthuthukisa ukuncintisana komkhiqizo. Emikhiqizweni evamile ye-PVC yangaphakathi efunwa kancane, iziqinisi ezijwayelekile zingahlangabezana nezidingo eziyisisekelo zokusetshenziswa kwesikhathi esifushane, yize ukuncishiswa kwekhwalithi okuncane kungavela ngemuva kokubekwa isikhathi eside.
Kuzo zonke izimo ezisezingeni eliphezulu, ukuthuthukela kuzinzisi ezihlanzekile kakhulu kuyitshalomali elidingekayo. Imikhiqizo ye-PVC ecacile, izinto zezokwelapha nezokudla ezisezingeni eliphezulu, kanye nezingxenye ze-PVC zokuhlobisa ngokunemba zidinga izindawo zokungcola eziphansi kakhulu ukuqinisekisa ukusebenza kahle nokuphepha kokukhanya. Imikhiqizo ye-PVC yobunjiniyela bangaphandle kumele isebenzise izinzisi ze-BaZn ezihlanzekile kakhulu ukuze imelane nokuguga okubangelwa ukungcola futhi igcine ukusebenza okuzinzile ezindaweni ezinzima.
Ekukhiqizeni kwangempela, iziqinisi ezihlanzekile kakhulu nazo zenza kube lula ukulungisa amaphutha efomula. Ukwakheka kwazo okuhlanzekile okuzinzile kunciphisa isidingo sezithasiselo ezisizayo ezikhokhela amaphutha okungcola, zinciphise imijikelezo yokulungisa amaphutha okukhiqiza futhi zehlise izindleko zezinto zokusetshenziswa eziphelele. Izinga lokuncipha kwezinsalela kanye nokuvumelana komkhiqizo okuthuthukisiwe kuthuthukisa ukusebenza kahle kokukhiqiza efektri kanye nedumela lemakethe.
Imibuzo Nezimpendulo
Q1: Kungani iziqinisi ze-PVC ezihlanzekile kancane zibangela ukushintsha kombala kanye nemvula?
