Kwiminyaka yakutshanje, ijeli ye-silica iye yavela njengenye yezona zinto ziguquguqukayo kwaye ziyimfuneko kumashishini ahlukeneyo, ukusuka ekugcinweni kokutya ukuya kwizicelo zonyango. Eyaziwayo ngolwakhiwo olukhethekileyo lweekhemikhali kunye neempawu zokufunxa ezimangalisayo, ijeli ye-silica iye yaba yinxalenye ephambili kwiimveliso kunye neenkqubo ezininzi kwihlabathi liphela.
Ijeli ye-silica, uhlobo olunamanzi lwe-silicon dioxide (SiO₂), ikakhulu yenziwe ngamathambo amancinane, adityanisiweyo anika indawo enkulu yomhlaba. Esi sakhiwo senza i-adsorbent egqwesileyo, ekwazi ukufunxa ukufuma kunye nezinye izinto ngokufanelekileyo. Ukukwazi kwayo ukugcina okanye ukukhulula iimolekyuli zamanzi ngokusekwe kwiimeko zokusingqongileyo kwenze ukuba ibe sisithako esibalulekileyo ekupakishweni kokutya, kumayeza, nakwizinto zokuthambisa.
Enye yezona zinto ziqhelekileyo zokusetyenziswa kwe-silica gel njenge-desiccant, into esusa umswakama emoyeni okanye kwiindawo ezivaliweyo. Kwipakethe yokutya, iipakethi ze-silica gel zihlala zibandakanyiwe ukukhusela izinto zokutya ukuba zibe ngumbumba okanye i-rancid ngokugcina indawo eyomileyo. Ngokufanayo, kwishishini lamachiza, i-silica gel isetyenziselwa ukuzinzisa ukuqinisekisa ukunyaniseka kunye nokusebenza kwamachiza ngexesha lokugcinwa kunye nokuthutha.
Ngaphandle kwendima yayo njenge-desiccant, ijeli ye-silica ifumene izicelo ezibanzi kwiimveliso zokuthambisa kunye ne-skincare. Iimpawu zayo zokufunxa ziyenza ilungele ukusetyenziswa kwiimaski zobuso, umgubo, kunye nezinye iimveliso zokhathalelo lwesikhumba, apho inceda ukufunxa ioyile egqithisileyo kwaye inciphise ukukhanya. Ukongezelela, ijeli ye-silica isetyenziswa ngokubanzi njenge-ejenti yokuqina kwiimveliso zokhathalelo lomntu, inika ukuhambelana okugudileyo kunye nokusabalalisa.
Kwicandelo lezonyango, i-silica gel ibonakalise ukuba yinto exabisekileyo ekudaleni iimveliso ezihambelana ne-biocompatible. Ubume bayo obungangeni kunye nobungenabuthi buyenza ilungele ukusetyenziswa kwizixhobo zonyango, ezifana nokufakelwa kunye neprosthetics. Ijeli ye-silica iphinda isetyenziswe kwimveliso yee-lens zoqhagamshelwano, apho ukuguquguquka kwayo kunye neempawu zokugcina amanzi ziqinisekisa induduzo kunye nokucaca kwabathwali.
Ukuguquguquka kwejeli ye-silica kunabela kwizicelo zamashishini ngokunjalo. Kwishishini lemichiza, i-silica gel isetyenziswe njengenkxaso ye-catalyst kwiindlela ezahlukeneyo zeekhemikhali, ukuphucula ukusebenza kakuhle kweenkqubo ngelixa kunciphisa iindleko. Ukuzinza kwayo kwe-thermal kunye nokuchasana nokuchithwa kweekhemikhali kwenza kube yinto efanelekileyo yokusetyenziswa kobushushu obuphezulu, njengokuveliswa kweglasi kunye neekeramics.
Njengoko amashishini eqhubeka nokuvela, imfuno yejeli ye-silica kulindeleke ukuba ikhule, iqhutywa ziipropathi zayo ezizodwa kunye nokuguquguquka. Abaphandi baphinda bahlolisise izicelo ezintsha, ezifana nokusebenzisa i-silica gel kwiinkqubo zokuhluza amanzi ukususa ukungcola kunye nokungcola emanzini. Ukongezelela, ukuqhubela phambili kwi-nanotechnology kuvumela ukuphuhliswa kwe-silica-based nanoparticles, ebambe isithembiso sokuhanjiswa kweziyobisi ezijoliswe kuyo kunye nezinye izicelo ezintsha.
Ekugqibeleni, i-silica gel ingaphezulu nje kwe-desiccant elula; sisixhobo esineenkalo ezininzi esidlala indima ebalulekileyo ekubumbeni amashishini anamhlanje. Ukukwazi kwayo ukufunxa, ukubhengeza, kunye nokuzinzisa kuyenza ibe yinto ebaluleke kakhulu ekutyeni, kumayeza, kwizinto zokuthambisa, nangaphaya. Njengoko ukuqhubela phambili kwezesayensi kunye netekhnoloji kuqhubeka nokuvula amathuba amatsha, ijeli ye-silica ikulungele ukuhlala iyinto ephambili kuqoqosho lwehlabathi, iqhuba ukwenziwa kwezinto ezintsha kunye nokuphucula umgangatho wobomi kwihlabathi liphela.
