Eminyakeni yamuva nje, ijeli ye-silica iye yavela njengenye yezinto eziguquguqukayo nezibaluleke kakhulu ezimbonini ezihlukahlukene, kusukela ekugcinweni kokudla kuya ekusetshenzisweni kwezokwelapha. Yaziwa ngesakhiwo sayo samakhemikhali esiyingqayizivele kanye nezakhiwo ezimangalisayo zokumunca, ijeli ye-silica isiyingxenye ebalulekile emikhiqizweni nasezinqubweni eziningi emhlabeni wonke.
Ijeli ye-silica, uhlobo olunezimbotshana lwe-silicon dioxide (SiO₂), ngokuyinhloko yakhiwe ngezimbotshana ezincane ezixhumene eziyinika indawo enkulu engaphezulu. Lesi sakhiwo senza kube i-adsorbent enhle kakhulu, ekwazi ukumunca umswakama nezinye izinto ngokuphumelelayo. Ikhono layo lokugcina noma lokukhulula ama-molecule amanzi ngokusekelwe ezimeni zemvelo liyenze yaba isithako esibalulekile ekufakweni kokudla, emithini yemithi, ngisho nasezimonyoni.
Enye yezinto ezisetshenziswa kakhulu ijeli ye-silica ifana ne-desiccant, into esusa umswakama emoyeni noma ezindaweni ezivalekile. Ekupakishweni kokudla, amaphakethe ejeli ye-silica avame ukufakwa ukuvimbela izinto zokudla ukuthi zingakhuntile noma zibe ne-rancid ngokugcina indawo eyomile. Ngokufanayo, embonini yemithi, i-silica gel isetshenziswa njengesizinzisi ukuze kuqinisekiswe ubuqotho nokusebenza kwezidakamizwa ngesikhathi sokugcina nokuthutha.
Ngaphandle kwendima yayo njenge-desiccant, ijeli ye-silica ithole ukusetshenziswa okubanzi embonini yezimonyo ne-skincare. Izici zayo zokumunca ziyenza ilungele ukusetshenziswa kumaski obuso, izimpushana, neminye imikhiqizo yokunakekelwa kwesikhumba, lapho isiza khona ukumunca uwoyela oweqile futhi inciphise ukukhanya. Ukwengeza, ijeli ye-silica isetshenziswa kabanzi njenge-ejenti yokuqina emikhiqizweni yokunakekelwa komuntu siqu, ihlinzeka ngokungaguquguquki okushelelayo nokusakazeka.
Emkhakheni wezokwelapha, ijeli ye-silica ifakazele ukuthi iyimpahla ebalulekile yokwakha imikhiqizo ehambisana ne-biocompatible. Imvelo yayo engenzi lutho futhi engenabo ubuthi iyenza ifanelekele ukusetshenziswa emishinini yezokwelapha, efana nezimila kanye nama-prosthetics. Ijeli ye-silica nayo isetshenziselwa ukukhiqizwa kwamalensi okuxhumana, lapho ukuguquguquka kwayo kanye nezindawo zokugcina amanzi kuqinisekisa ukunethezeka nokucaca kwabagqoki.
Ukuguquguquka kwejeli ye-silica kudlulela nasezisetshenziswa zezimboni. Embonini yamakhemikhali, ijeli ye-silica isetshenziswa njengokwesekwa kwe-catalyst ekuphenduleni kwamakhemikhali okuhlukahlukene, ithuthukisa ukusebenza kahle kwezinqubo ngenkathi kunciphisa izindleko. Ukuzinza kwayo okushisayo kanye nokumelana nokuwohloka kwamakhemikhali kuyenza ibe yinto ekahle yokusetshenziswa kwezinga lokushisa eliphezulu, njengokukhiqizwa kwengilazi nezitsha zobumba.
Njengoba izimboni ziqhubeka nokuvela, isidingo sejeli ye-silica kulindeleke ukuthi sikhule, siqhutshwa izici zayo eziyingqayizivele nokuvumelana nezimo. Abacwaningi baphinde bahlole izinhlelo zokusebenza ezintsha, ezifana nokusebenzisa ijeli ye-silica ezinhlelweni zokuhlunga amanzi ukuze basuse ukungcola nokungcola emanzini. Ukwengeza, intuthuko ku-nanotechnology ivumela ukuthuthukiswa kwe-silica-based nanoparticles, enesithembiso sokulethwa kwezidakamizwa okuhlosiwe nezinye izinhlelo zokusebenza ezintsha.
Ekuphetheni, i-silica gel ingaphezu nje kwe-desiccant elula; yizinto ezihlukene ezidlala indima ebalulekile ekulolongeni izimboni zesimanje. Ikhono layo lokumunca, ukukhangisa, kanye nokuzinzisa liyenza ibe yingxenye ebalulekile yokudla, imithi, izimonyo nangale kwalokho. Njengoba intuthuko yesayensi nezobuchwepheshe iqhubeka nokuvula amathuba amasha, ijeli ye-silica ikulungele ukuhlala iyinto ebalulekile emnothweni womhlaba, iqhubekisela phambili izinto ezintsha kanye nokwenza ngcono izinga lempilo emhlabeni wonke.
