Emkhakheni wezinto zokunamathisela ze-polymer, ukuguquguquka okukhulayo sekuqhubeke iminyaka eminingi.Ngesidingo semikhiqizo ehlala isikhathi eside futhi eqinile, ukuthuthukiswa kokunamathela kwe-polymer okuguquguqukayo sekuyinto ehamba phambili.Enye intuthuko ebonise isithembiso ukusetshenziswa kwezingxube ze-RDP polymer binder.
I-RDP, noma impushana ye-polymer ehlakazeka kabusha, i-polymer eyomiswa futhi yagaywa yaba yifomu lempushana, engase iphinde ihlakazwe oketshezini ukuze yakhe i-emulsion entsha noma ukunamathela.Impushana yenziwe ngamapolymer ahlukahlukene ahlanganisa i-vinyl acetate-ethylene (VAE), i-vinyl acetate-ethylene (VAEO), ne-vinyl acetate-ethylene ester (VA-VE).I-RDP isetshenziswe kabanzi ekwakhiweni kokunamathisela nokunamathisela kanye nasezintweni ezifaka udaka nokhonkolo.Izakhiwo zayo ezinhle kakhulu zokwenza ifilimu kanye nekhono lokuthuthukisa ukunamathela, ukucutshungulwa nokuguquguquka kwenza kube ukukhetha okudumile ezimbonini eziningi.
Uma ihlanganiswa namanye ama-polymers afana ne-polyvinyl acetate (PVA), irabha ye-styrene-butadiene (SBR) nerabha ye-carboxyl styrene-butadiene (XSB), i-RDP ingathuthukisa kakhulu ukuguquguquka komkhiqizo wokugcina.Lokhu kungenxa yekhono le-RDP lokwandisa ipulasitiki nokunwebeka kwama-polymers.Ngokusebenzisa lezi zithako ukwenza ifilimu eqinile, i-RDP ingathuthukisa amandla ebhondi yomkhiqizo wokugcina futhi iwenze umelane nokuqhekeka nokuwohloka.
Enye yezinzuzo eziyinhloko zokusebenzisa izingxube zokunamathela ze-polymer ye-RDP ukuguquguquka kwazo.Ingasetshenziswa kuma-substrates ahlukahlukene, kufaka phakathi izinkuni, ukhonkolo kanye nensimbi, ngaphandle kokudela ukusebenza noma ukuqina.Ukwengeza, ingakhiwa ngamazinga ahlukahlukene okuguquguquka kuye ngezidingo zokusetshenziswa kokugcina.Lokhu kuvumela ukuguquguquka okukhulu ekwakhiweni komkhiqizo kanye nekhono lokudala izixazululo zezinhlelo zokusebenza ezithile.
Enye inzuzo yokusebenzisa inhlanganisela ye-RDP polymer binder ukusebenza kahle kwayo kwezindleko.Izindleko zayo eziphansi uma kuqhathaniswa nezinye izinhlobo zokunamathisela kwenza kube inketho ekhangayo ezimbonini eziningi.Futhi kulula ukuyisebenzisa futhi ingafakwa kumaresiphi akhona ngaphandle kwezinguquko ezinkulu.
Inhlanganisela ye-RDP polymer binder ingathuthukisa ikhwalithi iyonke yomkhiqizo wokugcina.Ngenxa yokuthi inikeza ukuguquguquka okukhulu futhi ithuthukisa ukunamathela, inweba impilo yomkhiqizo futhi inciphise isidingo sokulungiswa njalo noma ukushintshwa.Ngokuhamba kwesikhathi, lokhu kungaholela ekongeni kwezindleko ezinkulu kanye nokwanda kokwaneliseka kwamakhasimende.
Ukusetshenziswa kwezingxube ze-RDP polymer binder kukhombisa isithembiso esihle ekwandiseni ukuguquguquka kwemikhiqizo ehlukahlukene.Ukuguquguquka kwayo, ukusebenza kahle kwezindleko, kanye nekhono lokuthuthukisa ikhwalithi iyonke yomkhiqizo wokugcina kuyenza ibe yinketho ebalulekile ezimbonini eziningi.Ukusetshenziswa kwezingxube zokunamathela ze-polymer ye-RDP kungenzeka kuqhubeke nokukhula ekudumeni njengoba isidingo semikhiqizo ehlala isikhathi eside futhi eqinile iqhubeka nokwanda.
