Eminyakeni yamuva nje, i-silica yokumunca ukudla, ikakhulukazi i-fumed silica, isithole ukunakwa okukhulu ngenxa yendima yayo ebalulekile ekuthuthukiseni izakhiwo emafutheni adliwayo. Isakhiwo esiyingqayizivele kanye ne-chemistry yendawo ye-fumed silica kuyenza ibe isengezo esisebenzayo sokuthuthukisa ukuthungwa, ukuzinza, kanye nenani lokudla ezinhlelweni zokudla. Lesi sihloko sihluza izinzuzo ezibalulekile kanye nezinqubo lapho i-silica yokumunca ukudla, ikakhulukazi i-fumed silica, ibeka isandla ekwakhiweni kwamafutha adliwayo, inikeza imininingwane ebalulekile kubakhiqizi nabahleli embonini yokudla.

I-silica yokumunca ukudla, ikakhulukazi i-fumed silica, isebenza njengesithako esisebenza ngezindlela eziningi emafutheni adliwayo ngokusebenza njengesakhiwo kanye nesikhundla samathukuthelo. Lesi sengezo sithuthukisa umuzwa womlomo kanye ne-viscosity yemikhiqizo esekelwe emafutheni, sivumela ukwakheka okunempilo okunezinga elincishisiwe lamafutha ngenkathi kugcinwa izici ezithandekayo zokuzwa. Izinzuzo zezempilo zokufaka i-silica esezingeni lokudla zihlanganisa ukugayeka kokudla okuthuthukisiwe kanye nokukhululwa kwezakhi zomsoco okulawulwayo, okuhambisana nesidingo sabathengi besimanje sokudla okusebenzayo. Izinkampani ezifana neShandong Zhonglian Chemical Co., Ltd. ibe yisikhungo ekuhlinzekeni i-fumed silica esezingeni eliphezulu eyenzelwe izicelo zokudla, iqinisekisa ukuphepha nokuthobela izindinganiso zamazwe ngamazwe.

I-silica enomusi ibonakala ngamaphakethe ayo amahle, angajwayelekile anendawo enkulu engaphezulu kanye ne-chemistry eyingqayizivele engaphezulu eyenza kube lula ukusebenzisana namandla namafutha adliwayo. Isakhiwo sayo esinobubanzi, esinobubanzi obuthathu sivumela ukumunca kahle kwamafutha nokujiya, sinikeze ukuqina nokuthuthukisa ukuthungwa. Imvelo ye-hydrophobic noma ye-hydrophilic engaphezulu ye-silica ingashintshwa ukuze ilungele izindlela zokupheka ezithile zokudla, ilungise ukuhambisana kwayo namafutha adliwayo ahlukahlukene. Ukuqonda lezi zakhiwo kubalulekile kubachwepheshe bokudla abahlose ukuthuthukisa ikhwalithi yomkhiqizo kanye nokuphila eshalofini ngokusebenzisa izithako ezintsha.

Indima esebenza ngayo i-fumed silica emafutheni adliwayo itholakala ekukwazi kwayo ukumunca nokubopha izakhiwo zamachibi emafutheni ngaphakathi kwenethiwekhi yayo, okubangela ukwanda kwe-viscosity nokuthuthukisa umuzwa emlonyeni. Lokhu kusebenzisana kunciphisa ukuhamba kwamafutha, kuvimbele ukuhlukana kwezinhlangothi futhi kuthuthukise ukuzinza komkhiqizo. Ngaphezu kwalokho, i-fumed silica ithonya ukuthungwa ngokudala ukungaguquguquki okukhilimu nokushelelayo, okungalingisa iphrofayili yezinzwa yemikhiqizo enamafutha aphezulu ngaphandle kokwandisa okuqukethwe kwekhalori. Izinqubo ezinjalo ziyigugu ekuthuthukiseni amafomula okudla anempilo ngaphandle kokudela ukwaneliseka komthengi.

Ngaphandle kwendima yayo yesakhiwo, i-silica yokudla esebenza njengomthamo iqhuba nezinzuzo zokudla ngokulawula ukutholakala kwamalipidi emzimbeni. Ukukhululwa kwe-oyela okulawulwa yi-fumed silica kusiza ekugayeni nasekutholakaleni kwezakhamzimba kancane kancane, okungase kuthuthukise ukusebenza kwamalipidi nokunciphisa ukwanda kwamalipidi egazini ngemuva kokudla. Lo mshikashika wokulawula ukuhlakazeka kwamalipidi usekela ukusetshenziswa kwamandla okungcono futhi ungase ube nomthelela ekuthuthukiseni impilo yenhliziyo nemithambo yegazi. Lezi zici zigcizelela ukubaluleka kokuhlanganisa i-silica esezingeni lokudla emafutheni adliwayo njengesithako esisebenzayo esinomthelela ekuthuthukiseni impilo.

I-Fumed silica isetshenziswa ezinhlobonhlobo zemikhiqizo yokudla okubalwa kuyo izinongo zokudla, ama-spreads, amasosi, kanye nemikhiqizo yokubhaka enamafutha aphansi, lapho ithuthukisa ukwakheka futhi yandisa isikhathi sokugcinwa. Ukuqanjwa okusha okuqhubekayo kubakhiqizi abanjengoShandong Zhonglian Chemical Co., Ltd. kusekela ukuthuthukiswa kwemikhiqizo ye-silica ethuthukisiwe eyenzelwe ukusetshenziswa ekudleni, okubalwa kuyo izinhlobo ze-nano ne-hydrophobic. Sibheke phambili, ukufakwa kwe-silica yokudla okumunca kuyalindeleke ukuthi kwandiswe ngokufunwa okukhulayo kwezinketho zokudla ezihlanzekile, eziphilile ezingadali ukwehla kwekhwalithi noma ukunambitheka.

I-silica yokumunca ukudla, ikakhulukazi i-fumed silica, idlala indima ebalulekile ekwakheni amafutha adliwayo ngokuthuthukisa ukwakheka, ukuzinza, nezinzuzo zokudla okunempilo. Izimfanelo zayo eziyingqayizivele nezinqubo zenza kube isithako esibalulekile ekwakhiweni kokudla kwesimanje okuhlose ukunciphisa okuqukethwe kwamafutha ngenkathi kugcinwa ikhwalithi yomkhiqizo. Izinkampani ezifana no-Shandong Zhonglian Chemical Co., Ltd. qhubeka nokwenza izinto ezintsha kulo mkhakha, uhlinzeka ngemikhiqizo ye-silica esezingeni eliphezulu yokudla esekela izixazululo ezisebenzayo nezisimeme embonini yokudla. Abakhiqizi bokudla nabahleli bayakhuthazwa ukuthi bahlole amandla e-fumed silica ukuhlangabezana nezidingo zemakethe eziguqukayo kanye nokuncanyelwa kwabathengi.
