Ukukhiqizwa kwePolyvinyl Chloride (PVC) Isikhumba sokufakelwa kuyinqubo eyinkimbinkimbi efuna ukuqina okuphezulu nokuqina kokuqukethwe. I-PVC iyi-thermoplastic esetshenziswa kabanzi eyaziwa ngokuguquguquka kwayo, kepha iyimvelo ingazinzile emazingeni okushisa aphezulu, kudinga ukusetshenziswa kwezikhutha. Ama-potassium-zinc angganilivilivilizer aqhamuke njengokuqamba okubalulekile kulo mkhakha, enikeza izinzuzo eziningi ngaphezu kwabagcinwe bendabuko. Lezi zikhuthazi zibaluleke ikakhulukazi embonini ye-PVC yokufakelwa kwesikhumba ngenxa yezindawo zazo zokuqinisa ukushisa okuphezulu kanye nezinzuzo zemvelo.
Izici nezakhiwo ze-potassium-zinc zizabeza
Ama-potassium-zinc angtulintshintshi, abizwa nangokuthi ama-k-zn esigcina, angxube ye-synergistic ye-potassium ne-zinc compound eklanyelwe ukuthuthukisa ukuqina kwe-PVC. Abakhuthazi babuyisela ngempumelelo abaqinisi abasebenza ngokuhola, abafake izingxenye ngenxa yezinkinga zemvelo nezempilo. Izakhiwo ezibalulekile ze-potassium-zinc ezithelelekile zihlanganisa ukuqina okungcono kakhulu kokushisa, ukucaca okuthuthukile, kanye nokuhambisana okuthuthukisiwe nokuqanjwa kwama-PVC ahlukahlukene.
* Ukuqina okushisayo:Ama-potassium-zinc angganilivilivilizer asebenza kahle kakhulu ekuvikeleni ukonakala kwe-PVC emazingeni okushisa aphakeme. Ngesikhathi sokucutshungulwa kwesikhumba sokufakelwa kwePVC, okuqukethwe kufakwa ngaphansi kokushisa okubalulekile, okungadala ukuthi amaketanga e-polymer ashiye phansi, okuholela ekulahlekelweni kwezakhiwo, kanye nokukhishwa kwe-hydrochloric acid (HCL). Ama-potassium-zinc esibalo asiza ukugcina ubuqotho be-PVC polymer chain, uqinisekise ukuthi izinto ezibonakalayo zigcina izakhiwo zalo ngisho nokuvezwa kokushisa okuningana.
* Ukusobala nokubamba umbala:Abakhuthazeleli banikela ekukhiqizweni kwemikhiqizo ecacile necacile ye-PVC. Bavimbela ukuphuzi namanye ama-regaling nezinye izindlela, baqinisekise ukuthi imikhiqizo yokugcina yesikhumba yokufakelwa igcina isikhalazo sabo sobuhle. Lokhu kubaluleke kakhulu kwizimboni zemfashini nezimoto, lapho ukuvela kwesikhumba sokwenziwa kuyinto ebalulekile yekhwalithi.
* Ukuphepha kwezemvelo:Enye yezinzuzo ezibalulekile ze-potassium-zinc Stungohines ubungane babo bezemvelo. Ngokungafani nokuqina okusekelwe ekuholeni, ama-potassium-zinc anggation awakhiphi izinto ezinobuthi ngesikhathi sokucubungula noma ukulahlwa. Lokhu kubenza babe ukukhetha okuphephile kwabakhiqizi nabasebenzisi bokugcina, ukuhambisana nesidingo esikhulayo sezinto ezizinzile nezingezona ezinobuthi ezimbonini ezahlukahlukene.
Izindlela zohlelo lokusebenza
Ukuhlanganiswa kwe-potassium-zinc Stutilivilizer ku-PVC kuhlanganisa izinyathelo eziningana, okwenzeka ngesikhathi esiteji esijabulisayo. Lezi zikhuthazo zingafakwa ngezindlela ezahlukahlukene, kufaka phakathi ukuhlanganiswa owomile, ukukhishwa, kanye nokubumba kokukhwabanisa.
I-1.dry ehlanganisiwe:E-Dry ehlanganisiwe, ama-potassium-zinc ukuqina ahlanganiswe ne-PVC resin nezinye izengezo ku-mixer esheshayo. Le ngxube isebhekwa amazinga okushisa aphezulu kanye namabutho ama-shear ukuqinisekisa ukusatshalaliswa okufanayo kwabakhuthazayo kulo lonke i-PVC Matrix. Le nqubo ibalulekile ekufezekiseni ukuzinza okungaguquki kuyo yonke i-batch ye-PVC.
2. Ukukhishwa:Ngesikhathi sokuxoshwa, i-PVC ehlanganisiwe ye-PVC yondliwe ye-extruder, lapho incibilikisiwe futhi ihlelwe khona. Abaqinisi baqinisekisa ukuthi izinto ze-PVC zihlala zizinzile futhi azihlali ngaphansi kwamazinga okushisa aphezulu nezingcindezi ezibandakanyeke ekukhishweni. I-PVC esetshenzisiwe ye-extrudy yasungulwa ngamashidi noma amafilimu, asetshenziswa ngemuva kwalokho ekwenziweni kwesikhumba sokufakelwa.
3. Ukubumba:Ngezicelo ezidinga ukwakheka okuningiliziwe kanye nemiklamo, ukuqashwa kokujova kuyaqashwa. I-PVC Compound, equkethe izibalo ze-potassium-zinc, ifakwe emgodini wokudala lapho ipholisa khona futhi iqina ibe yindlela oyifunayo. Abaqinisi ababamba iqhaza elibalulekile ekugcinweni kokuqina okushisayo kule nqubo, ukuvimbela izinkinga kumkhiqizo wokugcina.
Kungani ama-potassium-zinc ukuqina abizwa nge- "Kickers"
Igama elithi "Kicker" kumongo we-potassium-zinc Gcaning aqhamuka emandleni abo okusheshisa inqubo ye-PVC Plastisol ngesikhathi sokushisa. Ekwenziweni kwesikhumba sokufakelwa kwePVC, ukufeza i-gelation efiselekayo nokuhlanganiswa kwe-PVC Plastisol kubalulekile. I-Potassium-Zinc Stumaliviliviliviling Act njenge-Kickers ngokwehlisa amandla asebenze adingekayo ukuze uthole ukubheja, ngaleyo ndlela usheshise lonke inqubo. Le gelation esheshayo iyazuzisa ngoba iholela emijikelezweni yokukhiqiza esheshayo kanye nezinqubo zokukhiqiza ezisebenza kahle.
Izinzuzo nokusebenza
Ama-potassium-zinc esibalo anikela ngezinzuzo ezimbalwa zokusebenza ekukhiqizweni kwesikhumba sokufakelwa kwesikhumba se-PVC. Lokhu kufaka phakathi:
* Ukuqina okuthuthukile okushisayo:Lezi zikhutha zinikeza ukuqina okuphakeme kokushisa kuqhathaniswa nabaqinisi bendabuko, ukuqinisekisa ukuthi izinto ze-PVC zingamelana namazinga okushisa aphezulu ngaphandle kokonakaliswa. Lokhu kubaluleke kakhulu embonini yesikhumba yokufakelwa, lapho amashidi e-PVC namafilimu atholwa khona lapho kushisa khona ngezinqubo ezinjengokufaka nokugcona.
* Ikhwalithi Yomkhiqizo Ethuthukisiwe:Ngokuvimbela ukonakaliswa kanye nokudilizwa, ama-potassium-zinc ukuqina asiza ukukhiqiza isikhumba sekhwalithi esezingeni eliphakeme se-PVC esinephutha. Lokhu kuholela emkhiqizweni ongaguquguquki futhi onokwethenjelwa, okubalulekile ekuhlanganeni namazinga ezimboni kanye nokulindelwe kwamakhasimende.
* Ukuthobela imvelo:Ukusetshenziswa kwe-potassium-zinc Gentilizer kuqondanisa nezidingo ezikhulayo zokulawula nezokuthenga zabathengi bezinto zokwakha imvelo. Abakhuthele abadedeli izinto eziyingozi, okwenza inqubo yokukhiqiza iphephe futhi igcineke kakhulu.
* Ukusebenza kahle:Ukusetshenziswa kwe-potassium-zinc ukuqinisa kungathuthukisa ukusebenza kahle ngokunciphisa amathuba eziphutha ezinjenge-fisheyes, ama-gels, kanye nama-specks amnyama. Lokhu kuphumela ekuvuthweni okuphezulu kanye nezindleko eziphansi zokukhiqiza, kufaka isandla ekusebenzeni kahle kwenqubo yezomnotho.
Ukusetshenziswa kwe-potassium-zinc Stungoger embonini ye-PVC yokufakelwa kwesikhumba kufanekisela intuthuko ebalulekile kubuchwepheshe bokuqinisa izinto ezibonakalayo. Abakhuthazeleli bahlinzeka ngozi oludingekayo, ukucaca, kanye nokuphepha kwezemvelo okudingekayo ukuze kukhiqizwe imikhiqizo yesikhumba esezingeni eliphakeme. Njengoba imboni iqhubeka nokubeka phambili ukusimama nokuphepha, abaqinisi be-potassium-banc balungele ukudlala iqhaza elibaluleke ngokwengeziwe ngokuzayo kwezokukhiqiza lesikhumba se-PVC.
