I-Evonik Yethula I-SIPERNAT® 20 Precipitated Silica: Indawo Ephezulu Yokubonisa Ingaphezulu Iletha Izixazululo Ezithuthukisiwe Zokuvimbela Ukunqwabelana Kwezimboni Zokudla Nezokudla Kwezilwane

I-Evonik isethule ngokusemthethweni i-SIPERNAT® 20, uhlobo olusha lwe-precipitated silica oluklanyelwe ukubhekana nezinselelo ezikhona embonini ezinjengokunqwabelana kwempuphu, ukumunca umswakama kanye nokungahambi kahle kwempuphu ekusetshenzisweni kwezokudla nasekudleni kwezilwane.

Njenge-additive engasebenzi ngamakhemikhali enokuzinza okukhethekile, i-SIPERNAT® 20 ayisebenzisani nezingxenye eziyisisekelo zempahla eluhlaza, iqinisekisa ukuhlanganiswa okuphephile ezinhlobonhlobo ezibanzi zokudla kanye nezinhlanganisela zempushana yokuphakela. Ngokuba nendawo ekhombayo eminingi yobukhulu obungu-160 m²/g okungenani, isakhiwo sayo esinezimbobo ezintathu ezichazwe kahle sibamba ngempumelelo umswakama okhululekile kanye nezinhlanganisela eziguquguqukayo ngaphakathi kwe-matrix yempahla, okunciphisa ngqo ingozi yokuhlangana futhi kwandise isikhathi sokuphila kwemikhiqizo yempushana eqediwe.

Umkhiqizo ugqama ngamandla awo anamandla okumunca, anenani lokumunca le-DOA elisukela ku-215 kuya ku-255 ml/100g. Lokhu kusebenza kahle kokumunca uwoyela kuvumela ukuguqulwa okusebenzayo kwezithako eziwuketshezi ezifana neziqholo kanye neziqinisi zokudla okunomsoco zibe yimpushana egelezayo ngokukhululekile, okwandisa ukuguquguquka kokucubungula kwabakhiqizi. I-SIPERNAT® 20 iphinde ibe nokusatshalaliswa kosayizi wezinhlayiyana okulawulwa ngokuqinile kwe-30–80 μm, okuqinisekisa ukusatshalaliswa okusheshayo nokulinganayo kuyo yonke ingxube yempushana kanye nemiphumela engaguquguquki yokuvimbela ukunqwabelana nokukhuthaza ukugeleza.

Imininingwane eyengeziwe ebalulekile ihlanganisa ukulahleka okuphezulu kokomisa okungu-7% kanye nebanga le-pH eliphakathi nendawo elingu-6.0–7.0 ku-5% yokumiswa kwamanzi, ngakho-ke isengezo ngeke sishintshe izakhiwo ze-physicochemical zezinto zokwenziwa noma siphazamise izinqubo zokukhiqiza ezilandelayo. Wonke amapharamitha okusebenza ahlolwa ngokuhambisana nezindinganiso zamazwe ngamazwe ze-ISO ukuze kube nekhwalithi ethembekile, elandelekayo. Njengesithako esizinikele sokulwa nokunqwabelana nokukhuthaza ukugeleza kwama-powder ezithako zokudla kwabantu kanye nokudla kwezilwane, i-SIPERNAT® 20 isiza abakhiqizi ekwandiseni ukuzinza kokugcinwa nokusebenza kahle kokucubungula kwama-powder abo.
