Ukukhiqizwa kwesikhumba sokwenziwa se-polyvinyl chloride (PVC) kuyinqubo eyinkimbinkimbi edinga ukuzinza okuphezulu kokushisa kanye nokuqina kwento. I-PVC iyi-thermoplastic esetshenziswa kabanzi eyaziwa ngokuguquguquka kwayo, kodwa ayizinzile ngokwemvelo emazingeni okushisa aphezulu, okudinga ukusetshenziswa kweziqinisi. Iziqinisi ze-potassium-zinc zivele njengobuchwepheshe obubalulekile kulo mkhakha, zinikeza izinzuzo eziningi kuneziqinisi zendabuko. Lezi ziqinisi zibaluleke kakhulu embonini yesikhumba sokwenziwa se-PVC ngenxa yezakhiwo zazo ezinhle kakhulu zokuqinisa ukushisa kanye nezinzuzo zemvelo.
Izici kanye Nezakhiwo Zeziqinisi Ze-Potassium-Zinc
Iziqinisi ze-potassium-zinc, ezaziwa nangokuthiIziqinisi ze-K-Zn, ziyinhlanganisela ehambisanayo yamakhemikhali e-potassium ne-zinc aklanyelwe ukuthuthukisa ukuzinza kokushisa kwe-PVC. Lawa ma-stabilizer athatha indawo ngempumelelo yama-stabilizer asekelwe ku-lead, asuswe kakhulu ngenxa yezinkinga zemvelo nezempilo. Izakhiwo ezibalulekile ze-iziqinisi ze-potassium-zinckufaka phakathi ukuzinza kokushisa okuhle kakhulu, ukucaca okuthuthukisiwe, kanye nokuhambisana okuthuthukisiwe nezinhlobo ezahlukene ze-PVC.
*Ukuzinza Kokushisa:Iziqinisi ze-potassium-zinc zisebenza kahle kakhulu ekuvimbeleni ukuwohloka kwe-PVC emazingeni okushisa aphezulu. Ngesikhathi sokucubungula isikhumba sokwenziwa se-PVC, le nto ifakwa ekushiseni okukhulu, okungabangela ukuthi amaketanga e-polymer aqhekeke, okuholela ekushintsheni kombala, ekulahlekelweni kwezakhiwo zomzimba, kanye nokukhululwa kwe-hydrochloric acid (HCl). Iziqinisi ze-potassium-zinc zisiza ukugcina ubuqotho beketanga le-polymer ye-PVC, ukuqinisekisa ukuthi le nto igcina izakhiwo zayo ngisho nangaphansi kokushisa isikhathi eside.
*Ukucaca Nokubamba Umbala:Lezi ziqinisi zinegalelo ekukhiqizweni kwemikhiqizo ye-PVC ecacile nekhanyayo. Zivimbela ukuphuzi kanye nokunye ukushintsha kombala, ziqinisekisa ukuthi imikhiqizo yesikhumba yokwenziwa yokugcina igcina ukubukeka kwayo okuhle. Lokhu kubaluleke kakhulu embonini yemfashini neyezimoto, lapho ukubonakala kwesikhumba sokwenziwa kuyisici esibalulekile sekhwalithi.
*Ukuphepha Kwemvelo:Enye yezinzuzo ezibalulekile zeziqinisi ze-potassium-zinc ukuthi zinobungani nemvelo. Ngokungafani neziqinisi ezisekelwe kumthofu, iziqinisi ze-potassium-zinc azikhiphi izinto ezinobuthi ngesikhathi sokucubungula noma ukulahla. Lokhu kuzenza zibe ukukhetha okuphephile kwabakhiqizi kanye nabasebenzisi bokugcina, okuhambisana nesidingo esikhulayo sezinto ezihlala isikhathi eside nezingenabo ubuthi ezimbonini ezahlukahlukene.
Izindlela Zokusebenzisa
Ukuhlanganiswa kweziqinisi ze-potassium-zinc ekwakhiweni kwe-PVC kuhilela izinyathelo eziningana, ezivame ukwenzeka ngesikhathi sesigaba sokuhlanganiswa. Lezi ziqinisi zingafakwa ngezindlela ezahlukene, okuhlanganisa ukuxuba okomile, ukukhipha, kanye nokubumba ngomjovo.
1. Ukuxuba Okuomile:Ekuxubeni okomile, iziqinisi ze-potassium-zinc zixutshwa ne-resin ye-PVC nezinye izithasiselo ku-mixer enesivinini esikhulu. Le ngxube ibe isifakwa emazingeni okushisa aphezulu kanye namandla okusika ukuqinisekisa ukusatshalaliswa okufanayo kweziqinisi kuyo yonke i-matrix ye-PVC. Le nqubo ibalulekile ekufezeni ukuzinza okuqhubekayo kulo lonke iqoqo lezinto ze-PVC.
2. Ukukhipha:Ngesikhathi sokukhipha, inhlanganisela ye-PVC exutshwe okomile ifakwa ku-extruder, lapho incibilikiswa khona futhi ihlanganiswe ndawonye. Ama-stabilizer aqinisekisa ukuthi izinto ze-PVC zihlala zizinzile futhi aziboli ngaphansi kwamazinga okushisa aphezulu kanye nezingcindezi ezihilelekile ekukhipheni. I-PVC ekhishwe ibe isidalwa sibe amashidi noma amafilimu, asetshenziswa kamuva ekwenziweni kwesikhumba sokwenziwa.
3. Ukubumba Ngomjovo:Ezinhlelweni ezidinga izimo nemiklamo enemininingwane, kusetshenziswa ukubumba ngomjovo. Inhlanganisela ye-PVC, equkethe iziqinisi ze-potassium-zinc, ifakwa emgodini wesikhunta lapho iphola khona futhi iqine ibe yisimo esifunwayo. Iziqinisi zidlala indima ebalulekile ekugcineni ukuzinza kokushisa phakathi nale nqubo, zivimbela amaphutha kumkhiqizo wokugcina.
Kungani Ama-Potassium-Zinc Stabilizers Ebizwa ngokuthi “Ama-Kickers”
Igama elithi “kicker” kumongo weziqinisi ze-potassium-zinc livela ekhonweni lazo lokusheshisa inqubo yokwakheka kwama-plastisol e-PVC ngesikhathi sokushisa. Ekukhiqizweni kwesikhumba sokwenziwa se-PVC, ukufeza ukwakheka okufiselekayo kanye nokuhlanganiswa kwe-PVC plastisol kubalulekile. Iziqinisi ze-potassium-zinc zisebenza njengeziqinisi ngokunciphisa amandla okusebenza adingekayo ekulungisweni, ngaleyo ndlela kusheshiswe yonke inqubo. Lokhu kwakheka okusheshisiwe kuyazuzisa ngoba kuholela emijikelezweni yokukhiqiza esheshayo kanye nezinqubo zokukhiqiza ezisebenza kahle kakhulu.
Izinzuzo kanye Nokusebenza
Iziqinisi ze-potassium-zinc zinikeza izinzuzo eziningana zokusebenza ekukhiqizweni kwesikhumba sokwenziwa se-PVC. Lokhu kufaka phakathi:
*Ukuqina Kokushisa Okuthuthukisiwe:Lezi ziqinisi zinikeza ukuzinza kokushisa okuphezulu uma kuqhathaniswa neziqinisi zendabuko, okuqinisekisa ukuthi izinto ze-PVC zingamelana namazinga okushisa aphezulu ngaphandle kokuwohloka. Lokhu kubaluleke kakhulu embonini yesikhumba sokwenziwa, lapho amashidi namafilimu e-PVC efakwa khona ekushiseni ngesikhathi sezinqubo ezifana nokuqopha nokunamathisela.
*Ikhwalithi Yomkhiqizo Ethuthukisiwe:Ngokuvimbela ukuwohloka nokuguquka kombala, iziqinisi ze-potassium-zinc zisiza ekukhiqizeni isikhumba sokwenziwa se-PVC sekhwalithi ephezulu esinamaphutha ambalwa. Lokhu kuholela kumkhiqizo ohlala njalo nothembekile, obalulekile ekuhlangabezaneni nezindinganiso zemboni kanye nokulindelwe ngamakhasimende.
*Ukuthobela Imithetho Yezemvelo:Ukusetshenziswa kwezithambisi ze-potassium-zinc kuhambisana nezidingo ezikhulayo zokulawula kanye nezabathengi zezinto ezinobungani nemvelo. Lezi zithambisi azikhiphi izinto eziyingozi, okwenza inqubo yokukhiqiza iphephe futhi iqhubeke isikhathi eside.
*Ukusebenza Kahle Kokucubungula:Ukusetshenziswa kwezithambisi ze-potassium-zinc kungathuthukisa ukusebenza kahle kokucubungula ngokunciphisa amathuba okuba neziphambeko ezifana nama-fisheye, ama-gel, nama-black specks. Lokhu kuphumela ekuvuneni okuphezulu kanye nezindleko zokukhiqiza eziphansi, okufaka isandla ekusebenzeni kahle kwezomnotho kwenqubo yokukhiqiza.
Ukusetshenziswa kwezithambisi ze-potassium-zinc ku-Isikhumba sokwenziwa se-PVCimboni imele intuthuko enkulu kwezobuchwepheshe bokuzinzisa izinto. Lezi ziqinisi zihlinzeka ngokuzinza kokushisa okudingekayo, ukucaca, kanye nokuphepha kwemvelo okudingekayo ekukhiqizeni imikhiqizo yesikhumba sokwenziwa esezingeni eliphezulu. Njengoba imboni iqhubeka nokubeka phambili ukusimama nokuphepha, iziqinisi ze-potassium-zinc zilungele ukudlala indima ebaluleke kakhulu esikhathini esizayo sokukhiqizwa kwesikhumba sokwenziwa se-PVC.
