Kwiminyaka yakutshanje, ijeli ye-silica iye yavela njengenye yezona zinto zisebenziseka lula nezibalulekileyo kumashishini ahlukeneyo, ukusuka ekugcinweni kokutya ukuya kwizicelo zonyango. Eyaziwa ngesakhiwo sayo esikhethekileyo seekhemikhali kunye neempawu zayo zokufunxa ezimangalisayo, ijeli ye-silica iye yaba yinxalenye ebalulekileyo kwiimveliso ezininzi kunye neenkqubo kwihlabathi liphela.
Ijeli yeSilica, uhlobo olunemingxuma ye-silicon dioxide (SiO₂), yenziwe ikakhulu ziimbobo ezincinci, ezidibeneyo ezinika indawo enkulu yomphezulu. Olu lwakhiwo luyenza ibe yindawo ebalaseleyo yokungenisa umswakama, ekwaziyo ukufunxa umswakama kunye nezinye izinto ngokufanelekileyo. Ukukwazi kwayo ukugcina okanye ukukhulula iimolekyuli zamanzi ngokusekelwe kwiimeko zendalo kuyenze yaba sisithako esibalulekileyo ekupakishweni kokutya, amayeza, kwanezithambiso.
Enye yezona ndlela zixhaphakileyo zokusebenzisa i-silica gel kukuyi-desiccant, into esusa umswakama emoyeni okanye kwiindawo ezivalekileyo. Kwiphakheji yokutya, iipakethi ze-silica gel zihlala zifakwa ukuthintela ukutya ukuba kungakhuli okanye kubole ngokugcina indawo eyomileyo. Ngokufanayo, kwishishini lamayeza, i-silica gel isetyenziswa njengesiqinisi ukuqinisekisa ukuthembeka nokusebenza kakuhle kwamayeza ngexesha lokugcina nokuthutha.
Ngaphandle kwendima yayo njenge-desiccant, i-silica gel ifumene ukusetyenziswa okukhulu kwimizi-mveliso yokuthambisa kunye nokhathalelo lolusu. Iimpawu zayo zokufunxa zenza ukuba ilungele ukusetyenziswa kwiimaski zobuso, iipowders, kunye nezinye iimveliso zokhathalelo lolusu, apho inceda ukufunxa ioyile egqithisileyo kunye nokunciphisa ukukhanya. Ukongeza, i-silica gel isetyenziswa kakhulu njenge-arhente yokutyeba kwiimveliso zokhathalelo lomntu, inika ukuqina okugudileyo nokusasazekayo.
Kwicandelo lezonyango, ijeli ye-silica ibonakalise ukuba yinto exabisekileyo yokwenza iimveliso ezihambelana nebhayoloji. Indalo yayo engasebenziyo nengenatyhefu yenza ukuba ifaneleke ukusetyenziswa kwizixhobo zonyango, ezifana nee-implants kunye nee-prosthetics. Ijeli ye-silica ikwasetyenziswa ekuveliseni iilensi zoqhagamshelwano, apho ukuguquguquka kwayo kunye neempawu zokugcina amanzi ziqinisekisa intuthuzelo kunye nokucaca kwabanxibi.
Ukuguquguquka kwejeli ye-silica kufikelela nakwiindlela zokusebenza kwimizi-mveliso. Kwishishini leekhemikhali, ijeli ye-silica isetyenziswa njengenkxaso ye-catalyst kwiindlela ezahlukeneyo zeekhemikhali, iphucula ukusebenza kakuhle kweenkqubo ngelixa inciphisa iindleko. Uzinzo lwayo kubushushu kunye nokumelana nokuwohloka kweekhemikhali kuyenza ibe yinto efanelekileyo yokusetyenziswa kubushushu obuphezulu, njengakwimveliso yeglasi kunye neeseramikhi.
Njengoko amashishini eqhubeka nokutshintsha, kulindeleke ukuba imfuno yejeli ye-silica ikhule, iqhutywa ziimpawu zayo ezizodwa kunye nokuziqhelanisa. Abaphandi bakwahlola ukusetyenziswa okutsha, njengokusebenzisa ijeli ye-silica kwiinkqubo zokucoca amanzi ukususa ukungcola kunye nezinto ezingcolisayo emanzini. Ukongeza, ukuqhubela phambili kwi-nanotechnology kuvumela uphuhliso lwee-nanoparticles ezisekelwe kwi-silica, ezithembisa ukuhanjiswa kwamayeza athile kunye nezinye izicelo ezintsha.
Ukuqukumbela, ijeli ye-silica ayisiyo nje i-desiccant elula; yinto enamacala amaninzi edlala indima ebalulekileyo ekubumbeni amashishini anamhlanje. Amandla ayo okufunxa, ukufunxa, nokuzinzisa ayenza ibe yinxalenye ebalulekileyo yokutya, amayeza, izinto zokuthambisa, nakwezinye izinto. Njengoko inkqubela phambili yesayensi netekhnoloji iqhubeka nokuvula amathuba amatsha, ijeli ye-silica ikulungele ukuhlala iyinto ebalulekileyo kuqoqosho lwehlabathi, iqhuba ubuchule kwaye iphucula umgangatho wobomi kwihlabathi liphela.
