Ukuqiniswa kwerabha
Ukuqinisa i-silica yenjoloba kusetshenziswa kabanzi njenge-ejenti eqinisayo embonini yenjoloba, ibalwa ku-70% wengqikithi yokusetshenziswa. Ikakhulukazi uma kukhiqizwa imikhiqizo yerabha emhlophe, enemibala kanye nekhanyayo{2}, ifaneleka kakhulu ngenxa yokuthi umbala omhlophe we-silica kulula ukuwufaka umbala. Isibonelo, amandla okuqinile werabha ye-silicone engaqinisiwe aweqi ku-0.4MPa. Ngemva kokuqiniswa nge-silica evuthayo, amandla angakhuphuka izikhathi ezingu-40.
I-ejenti yokukhohlisa
I-silica inendawo enkulu futhi inkomba ye-refractive ye-1.45 kuya ku-1.50. Ifilimu kapende equkethe i-hydrated silica matting agent izoboniswa lapho ukukhanya kungena, ngaleyo ndlela yakhe ukubukeka kwe-matte nokumathise okunomphetho ocwebezelayo. Izinhlayiya ze-silica evuthayo zixega, futhi inani lezinhlayiya ngeyunithi yesisindo likhulu kunalelo le-silica enciphile. Ngakho-ke, ngaphansi kwesamba esifanayo sokwengezwa, i-silica evuthayo inomphumela wokulinganisa ophezulu kanye nokucaca okungcono.
Sebenzisa njenge-abrasivus
Ngokungeziwe endaweni yayo enkulu, i-hydrated silica nayo inomthamo oqinile we-adsorption. Ngakho-ke, i-hydrated silica ingenye yezinhlobo eziyinhloko ze-abrasives yokuxubha amazinyo okwamanje. Ngenxa yokucaca okuphakeme nama-abrasives e-silica evuthayo, izithako eziningi zomuthi wokuxubha acwebe njengekristalu ziqukethe i-silica evuthayo.
Isetshenziselwa ukunamathisela nokuqinisa iphepha
I-silica enamanzi inokumelana okuhle nokugqokwa namandla. Njengoba kushiwo ngenhla, "imhlophe" kakhulu. Ngakho-ke, uma i-hydrated silica isetshenziswa ephepheni, ingathuthukisa ubumhlophe nokufiphaza kwephepha, ilenze liguge kakhulu-limelane nowoyela-limelane nowoyela{3}}futhi libe nokucwebezela okungcono. Isibonelo, ukungeza i-silica evuthayo engu-1-2% ku-newsprint kunganciphisa isisindo sayo ngo-10%, kuthuthukise amandla ayo futhi kuvimbele ukungena kukayinki.
Umphumela wokuqeda{0}}ukulungisa
Uma isetshenziswa kuma-adhesives nama-sealants, i-silica e-hydrated ingadlala indima ekulawuleni i-rheology, ukuvimbela ukuvela kwe-sedimentation, ukuvimbela ukugoqa kanye nokuqinisa. Ukwengeza, i-silica evuthayo, nokusebenza kwayo okuphezulu, isetshenziswa kakhulu njengesilungisi se-rheology, i-anti{1}}i-ejenti yokuhlalisa kanye ne-dispersant emkhakheni wamapende, oyinki nama-coatings.
