Ukuhlaziywa Okubanzi Kwe-Silica (SiO₂) Ekuhlungeni Uwoyela Wemifino: Izicelo Zezobuchwepheshe

Kufaka phakathi izici zomkhiqizo, izimiso zobuchwepheshe, amamethrikhi ohlelo lokusebenza, kanye nobuchwepheshe obusha

I. Izimpawu Zomkhiqizo kanye Nezimfuneko Zobuchwepheshe Ze-Silica

Ukusebenza okuphezulu kwe-Adsorption

I-silica (SiO₂), enokwakheka kwayo okunezimbotshana nendawo ethile ephezulu (imvamisa engu-150–600 m²/g), idonsa kahle izinsini, ama-ion ensimbi (isb., i-iron, ithusi), i-pigments, imikhiqizo ye-oxidation, nezinto eziyingozi (isb, i-benzo(a)pyrene, i-aflatoxin B1) emafutheni emifino.

Ukusebenza Kwe-Decolorization: Ukuhlola kubonisa ukuthi ukungeza u-0.1% we-silica kufeza ukuhlukaniswa kombala okuqhathaniswa nobumba obucushiwe obungu-0.5% kuyilapho kugcinwa umbala kawoyela wemvelo futhi kugwenywa ukuwohloka kwekhwalithi yezinzwa.
Ubungane Bendawo: Ithobelana nezindinganiso zomkhiqizo oluhlaza (isb., T/COCIA 33-2024), okungeyona ubuthi, okugaywa kabusha, futhi kulungele ukuhluzwa kukawoyela wezinga lokudla.

Ukuzinza Kwamakhemikhali

I-silica ihlala izinzile ngaphansi kwamazinga okushisa aphezulu (≤200℃) nasezindaweni ezine-acidic/alkaline, okuyenza ifanele izinqubo zezinga lokushisa eliphezulu njenge-脱酸 (i-deacidification) kanye ne-脱胶 (i-degumming).

II. Izimiso zobuchwepheshe kanye Nokuthuthukisa Inqubo

I-Adsorption Mechanism

I-Adsorption ebonakalayo: Ithwebula ukungcola okuyi-macromolecular (isb, ama-phospholipids, i-saponified matter) ngezakhiwo ezinezimbotshana.
I-Chemical Adsorption: Amaqembu e-surface hydroxyl (-OH) enza izibopho zokuxhumanisa nama-ion ensimbi, ehlisa izinsalela zensimbi enzima.
I-Synergistic Effect: Uma ihlanganiswa nobumba olucushiwe, i-silica inciphisa ukusetshenziswa kobumba ngo-20-30%, inciphisa udoti oqinile.

Amasistimu Okuhlunga Okusha

Isihlungi Esonga Amandla: Sisebenzisa izikrini ezinezendlalelo eziningi (isb, amafreyimu okuhlunga okuqala, esibili, esithathu) nama-agitators ukuze kuthuthukiswe ukuxubana, ukuthuthukisa ukusebenza kahle kokuhlunga ngamaphesenti angaphezu kuka-30 nokuvimbela ukuvinjwa.
I-Automation: Ihlanganisa izinzwa zokucindezela kanye nama-valve okuqapha ukucindezela kwesikhathi sangempela kanye nokushintshwa kwesihlungi okufika ngesikhathi.

III. Amamethrikhi ohlelo lokusebenza nokuhlolwa kokusebenza

Izinkomba Zokusebenza Ezibalulekile

Umthamo We-Adsorption: 0.1–0.3 mg benzo(a)pyrene noma 0.05–0.15 mg i-aflatoxin B1 igremu ngalinye lesilica.
I-Decolorization Rate: Kuwoyela kabhekilanga, i-0.1% ye-silica inyusa ukubola ibe ngu-85-90% futhi yehlisa i-phosphorus ibe ngaphansi kuka-10 mg/kg.
Ukuzinza Kwe-Oxidative: Kwelula isikhathi sokungeniswa kwe-oxidation ngo-30-50%, kuthuthukisa impilo yeshalofu.

Amazinga Ezemvelo Nokuphepha

Isitifiketi Sebanga Lokudla: Ihlangabezana ne-GB 25576-2010 (China) noma i-FDA 21 CFR 172.480 (US), iqinisekisa ukuthi akukho ukungcoliswa kwensimbi enzima/microbial.
Ukuhambelana Kwemfucuza: I-silica ephinda isetshenziswe kabusha inciphisa izinsalela ngo-40% uma kuqhathaniswa nezinqubo zendabuko.

IV. Amathrendi Ezobuchwepheshe

Ukuguqulwa Okusebenzayo

Ukuguqulwa kobuso (isb, ukwelashwa nge-hydrophobic) kuthuthukisa ukukhangiswa okukhethekile kokungcola okuthile (isb., ama-fatty acids amahhala).

Ukuhlanganisa Okuhlakaniphile

Ukuqapha okukude okuqhutshwa yi-IoT kanye nokwenza kahle okunamandla kunciphisa izindleko zokungenela okwenziwa ngesandla.

Ukuthuthukiswa Kwenqubo Eluhlaza

Ikhuthaza ukomiswa kwamandla aphansi ekukhiqizweni kwe-silica ukunciphisa ukukhishwa kwekhabhoni.

Ukuze uthole amapharamitha wobuchwepheshe anemininingwane noma idatha yokuhlola (isb, ukuhambisana kohlobo lukawoyela), bheka imibiko yemboni noma amalungelo obunikazi (isb, CN 210645372 U, CN 212283147 U).
