Isingeniso sendlela yemvula ye-silica dioxide
I-silica ye-precipitation method ingumkhiqizo wamakhemikhali we-inorganic osetshenziswa kabanzi emikhakheni eminingi. Ukulungiswa kwayo kuhilela ukuphendula ama-silicates ancibilikayo njenge-sodium silicate ene-asidi ukuze enze ama-silicate precipitates, abese engaphansi kokuguga, ukuhlunga, ukugeza, ukomiswa, nezinye izinqubo zokuthola umkhiqizo wokugcina.
Mayelana nezakhiwo ezibonakalayo, iyimpushana emhlophe e-amorphous enendawo enkulu ethile engaphezulu kanye nekhono eliqinile lokukhanga. Ingakwazi ukukhangisa izingxenye zamagesi kanye noketshezi futhi inezinhlelo zokusebenza kuma-adsorbents. Ukusabalalisa usayizi wezinhlayiyana kuyalawuleka, futhi osayizi bezinhlayiyana ezincane bangathuthukisa umphumela wokuqinisa enjoloba, bathuthukise izakhiwo zemishini yemikhiqizo yenjoloba, futhi ziyizithasiselo ezibalulekile embonini yenjoloba njengokukhiqiza amathayi; Ezingubo zokugqoka, ingathuthukisa i-rheology, i-anti settling, kanye nokumelana nesimo sezulu, okwenza ukunamathela kusetshenziswe ngokulinganayo futhi kuhlale isikhathi eside ekubukeni. Mayelana nezakhiwo zamakhemikhali, inokuqina kwamakhemikhali aphezulu futhi imelana nokuguguleka kwe-asidi ne-alkali. Isebenza kahle emkhakheni wezisekelo ze-catalyst yamakhemikhali, ihlinzeka ngesisekelo sokunamathela esizinzile sama-catalysts. Isakhiwo sayo esinezimbotshana sisiza ukuthintana phakathi kwama-reactants nama-catalysts, kuthuthukise ukusebenza kahle kwe-catalytic. Ukuzinza okuhle kokushisa, izakhiwo ezizinzile emazingeni okushisa aphezulu, ezifanele amasu okucubungula izinga lokushisa eliphezulu noma ukulungiswa kwezinto eziphikisana nokushisa.
Embonini yokudla, i-silica enemvula ivame ukusetshenziswa njenge-anti-caking agent ukuvimbela ukunqwabelana kokudla nokuqinisekisa ukuxega nokugeleza kwemikhiqizo, njengosawoti kanye nobisi lwempushana; Emkhakheni wemithi, ingasetshenziswa njenge-excipient yezidakamizwa ukuze kuthuthukiswe i-fluidity kanye nokucindezelwa kwezidakamizwa, ukwenza lula ukubunjwa kokubunjwa, kanye nokukhangisa ukungcola emithini, ngaleyo ndlela kuthuthukiswe ubumsulwa bezidakamizwa nokuzinza; Embonini yephepha, ingathuthukisa amandla, ubumhlophe, nokufiphala kwephepha, ithuthukise ukusebenza kokuphrinta nokubhala kwephepha; Embonini yezimonyo, ama-thickeners, stabilizers, nama-adsorbents avamile, angathuthukisa ukuthungwa nokuzwakala kwezimonyo, amunce amafutha kanye nomjuluko okhishwa isikhumba, futhi ugcine isikhumba somile. Kafushane, i-silica enciphayo, enezici zayo ezihlukile, idlala indima ebaluleke kakhulu ezimbonini eziningi ezifana nerabha, okokugqoka, izinto ezithwala ama-catalyst, ukudla, imithi, ukwenza amaphepha, izimonyo, njll. Iwumsebenzi obaluleke kakhulu embonini yesimanje.
