Uma usebenza emkhakheni wokudla, imithi, noma izimonyo, kungenzeka ukuthi uke wahlangana negama elithi "i-food grade fumed silica" izikhathi ezingenakubalwa. Kodwa into eyiqiniso — akuzona zonke izinhlobo ze-silica ezifanayo, futhi leyo ephephile ukuthi ingadliwa? Lokho kungumdlalo ohluke ngokuphelele. I-food grade fumed silica iyi-powder enhle kakhulu, engabonakali kahle, eyi-amorphous silicon dioxide, ecutshungulwe ukuze ihlangabezane nezindinganiso eziqinile zokuphepha zokudliwa ngumuntu. Akusiyona nje into yokugcwalisa engahleliwe; iyisengezo esibalulekile esisebenzayo esivimbela izinto eziyimpuphu ekuhlanganeni, siqinisekisa ukuthi zihamba kahle emigqeni yokukhiqiza, futhi size sizinzise izinhlanganisela eziwuketshezi. Cabanga ngaleyo nhlanganisela yezinongo ekhishini lakho noma leyo mpushana yokuphuza — ngaphandle kwe-food grade fumed silica esebenza njenge-anti-caking agent, ubungabhekana nezigaxa eziqinile ezingasebenziseki. Imakethe yomhlaba wonke ye-fumed silica ikhuphuka ngokuqhubekayo, futhi imibiko yezimboni ibikezela ukuthi izofinyelela ngaphezu kwezigidi eziyizinkulungwane eziyisigidi ezi-1.5 ngo-2028, futhi ingxenye ye-food-grade ingumshayeli omkhulu. Ngakho-ke, uma uthola le nto ukuyisebenzisa emigqeni yakho yokukhiqiza, kungcono ukuthi wazi ukuthi ufuna ini.

Yini eyenza i-fumed silica yezinga lokudla ihluke kangaka kwezinye izinhlobo ze-silicon dioxide yindawo yayo ephakeme kakhulu — sikhuluma ngama-200 kuya ku-400 square metres ngegramu. Lokho kufana nokusabalalisa igremu yempushana endaweni enkulu njenge-tennis court. Lendawo enkulu yiyona enika amandla amahle okumunca nokujiya. Ngaphezu kwalokho, ngenxa yokuthi i-amorphous hhayi i-crystalline, ayinabo ubungozi bokuphefumula obufanayo ne-crystalline silica. I-FDA ne-EFSA zombili ziyivumele ukuthi isetshenziswe ekudleni, kodwa kuphela uma ikhiqizwa ngaphansi kwezimo eziqinile ze-GMP. Lapho-ke ikhwalithi yomthengisi wakho iqala ukubaluleka, ngoba akubona bonke abakhiqizi abadlala ngemithetho efanayo.

Ake ngikwazise ngo-I-Shandong Zhonglian Chemical Co., Ltd.— igama elihamba phambili embonini yokukhiqiza i-silica. Inezizinda eShandong, eChina, le nkampani ayiyona nje into edlulayo. Isebenze iminyaka, yakha idumela lokukhiqiza imikhiqizo ye-silicon dioxide esezingeni eliphezulu ehlangabezana namazinga omhlaba. Inesitifiketi se-ISO9001, okusho ukuthi uhlelo lwayo lokuphatha ikhwalithi lusemthethweni. Futhi abenzi nje okuncane; batshale imali enkulu emandleni ocwaningo nokuthuthukisa, behlala belungisa futhi bethuthukisa izinqubo zabo zokukhiqiza ukuze bakhiphe ikhwalithi yomkhiqizo engaguquki futhi ethembekile. Uma usebenzisa i-fumed silica yezinga lokudla ezintweni ezibucayi njengemithi noma ukucubungula ukudla, ukungaguquki akuyona into enhle — kuyinto ebalulekile.

Okuhlukanisa ngempela i-Zhonglian ukufinyelela kwabo emhlabeni wonke. Abathengisi nje kubakhiqizi baseShayina bendawo; bahlinzeka izinkampani emhlabeni wonke — eYurophu, eNyakatho Melika, eNingizimu-mpumalanga ye-Asia, noma yikuphi. I-ikhathalogi yomkhiqizoizinhlobo ezingaphezu kuka-150 zemikhiqizo ye-silica yezinga lokudla, yemithi, neyezimboni. Lolu hlobo lwezinhlobonhlobo lukutshela ukuthi bayakwazi abakwenzayo. Noma ngabe udinga ukusatshalaliswa okuthile kosayizi wezinhlayiyana, ukwelashwa okuthile kwendawo engaphezulu, noma isixazululo esikhethekile sokupakisha, kungenzeka ukuthi bake basebenza nokuthile okufanayo ngaphambili. Ithimba labo liyaqonda ukuthi i-fumed silica yezinga lokudla akuwona umkhiqizo olingana wonke umuntu, futhi bazimisele ukusebenza nawe ukuze uthole imininingwane efanele. Lelo zinga lokuvumelana nezimo liyivelakancane emhlabeni wokuhlinzekwa kwamakhemikhali, futhi empeleni ngesinye sezizathu eziyinhloko ezenza abantu baqhubeke bebuya kubo.

Kulungile, ake singene emgqeni wokuthi kungani i-fumed silica yezinga lokudla yakwaShandong Zhonglian igqama phakathi kwezinye. Okokuqala, ubumsulwa. Sikhuluma ngama-99.8% ubuncane be-silicon dioxide, kanti izinsimbi ezinzima njenge-lead, i-arsenic, ne-mercury zigcinwa zingaphansi kwemikhawulo eqinile yemithetho. Lokhu akukhona nje okungashiwo — banemibiko yokuhlola yezinkampani zangaphandle efakazela lokhu. Ezinhlelweni zokudla nezemithi, amazinga okungcola angakwenza noma aphule ukuphepha komkhiqizo wakho, futhi i-Zhonglian ikuthatha ngokungathi sína. Inqubo yabo yokukhiqiza isebenzisa izinto ezingcolile eziphakeme kanye nezimo zokusabela ezilawulwayo ukuze kuqinisekiswe ukuthi umkhiqizo wokugcina uhlanzekile ngangokunokwenzeka. Akukho zindlela ezimfishane, akukho ukugwema.

Omunye umehluko omkhulu indawo engaphezulu elawulwayo kanye nosayizi wezinhlayiya. Ngokuya ngalokho okusebenzisa i-silica kukho, ungase udinge umkhiqizo onobubanzi obuthile bendawo engaphezulu. Mhlawumbe uyisebenzisa njenge-flow agent enhlanganisweni yempuphu ephuzwayo futhi udinge izinhlayiya ezincane ukuze zihlakazeke kangcono. Noma mhlawumbe uyifaka ekwakhiweni kwethebhulethi yemithi njenge-glidant futhi udinge usayizi othile wezinhlayiya ukuze uthole izakhiwo ezinhle zokugeleza. I-Zhonglian inikeza izinhlobo ezimbili ze-hydrophilic ne-hydrophobic ze-food grade fumed silica, okukunikeza ukuguquguquka ngokuya ngohlelo lwakho lokusebenza. Izinhlobo ze-hydrophilic zisebenza kahle ezinhlelweni ezinamanzi, kuyilapho izinhlobo ze-hydrophobic zingcono ekwakhiweni okusekelwe emafutheni noma ezindaweni ezinomswakama. Lokhu kuguquguquka komkhiqizo kusho ukuthi awudingi ukuyekela ukusebenza ngenxa yokuthi umhlinzeki wakho unekhathalogi elilinganiselwe.

Ngaphandle nje kwezici ezingaphezulu, kunenkinga yokungaguquguquki engiyikhulume ngaphambili. Noma yimuphi umkhiqizi angakhiqiza ibhadi elihle ngezikhathi ezithile.
