I-Titanium dioxide (TiO2) yi-pigment emhlophe eguquguqukayo esetyenziswa kwiintlobo ngeentlobo zemizi-mveliso, kuquka iipeyinti, iingubo, iiplastiki kunye nezithambiso. Iimpawu zayo ezizodwa zenza ukuba ibe yinto ebalulekileyo ekufezekiseni umbala ofunekayo, ukungabonakali kunye nokukhanya kwemveliso yakho. Nangona kunjalo, ukuze uqonde ngokupheleleyo uncedo lwe-titanium dioxide, kubalulekile ukuqinisekisa ukusasazwa okusebenzayo ngexesha lokusetyenziswa. Ukusasazwa ngokufanelekileyo kweTiO2 powder okanyeukusasazwa kwetitanium dioxidekubaluleke kakhulu ekwandiseni ukusebenza kwayo kunye nokufezekisa iziphumo ezinqwenelekayo. Kweli nqaku siza kujonga ezinye iingcebiso zokusasaza ngokufanelekileyo i-titanium dioxide ukuze kuphuculwe ukusetyenziswa kwayo kumashishini ahlukeneyo.
1. Qonda ukusasazwa kwe-titanium dioxide
Ngaphambi kokuba uhlolisise kwiingcebiso zokusasazwa okusebenzayo, kubalulekile ukuqonda ingcamango yokusasazwa kunye nokubaluleka kwayo kwizicelo ze-titanium dioxide. I-Dispersion ibhekiselele kwi-uniform distribution of TiO2 particles in a medium as a liquid or solid matrix. Ukusabalalisa okufanelekileyo kuqinisekisa ukuhanjiswa okufanayo kweengqungquthela ze-titanium dioxide, ukuthintela i-agglomeration kunye nokukhuthaza ukusebenza kakuhle kwemveliso yokugqibela.
2. Khetha indlela efanelekileyo yokusasazwa kwetitanium dioxide
Kukho iindlela ezininzi zokusasazatitanium dioxide, kubandakanywa ukusabalalisa okumanzi, ukusabalalisa okomileyo, unyango olungaphezulu, njl. Ukukhethwa kwendlela yokusabalalisa kuxhomekeke kwisicelo esithile kunye neempawu ze-TiO2 dispersion medium. Ngokomzekelo, kwishishini lepeyinti kunye neengubo, ukusabalalisa okumanzi kudla ngokusetyenziswa ngokusebenzisa i-dispers-speed-speed dispersers okanye i-media mills ukuphumeza ukusabalalisa i-particle efanayo.
3. Sebenzisa iimveliso zetitanium dioxide ezikumgangatho ophezulu
Umgangatho we-titanium dioxide powder okanye i-dispersion idlala indima ebalulekileyo ekufezekiseni ukusabalalisa okusebenzayo. Iimveliso ezikumgangatho ophezulu we-titanium dioxide kufuneka ziphume kubaboneleli abathembekileyo ukuqinisekisa ubungakanani besuntswana elingaguqukiyo, imilo kunye nokugqitywa komphezulu. Iimveliso ezikumgangatho ophezulu we-titanium dioxide zisasazeka ngokulula kwaye zibonelela ngokusebenza okuphuculweyo kwiinkqubo ezahlukeneyo.
4. Lungiselela ifomula kunye nenkqubo yeeparamitha
Ukongeza ekukhetheni indlela echanekileyo yokusasazwa kunye neemveliso ezikumgangatho ophezulu weTiO2, ukongeza ukwakheka kunye neeparamitha zenkqubo nako kubalulekile ukuphumeza ukusasazwa okusebenzayo. Izinto ezifana ne-titanium dioxide concentration, ukhetho lwe-dispersant, kunye neemeko zokucubungula (umzekelo, ubushushu, izinga lokucheba) kunokuchaphazela kakhulu inkqubo yokusasazwa. Ngokuhlengahlengisa ngononophelo ezi parameters, abavelisi banokufezekisa ngcono ukusasazwa kunye nokuphucula ukusebenza kwe-titanium dioxide kwiimveliso zabo.
5. Sebenzisa izixhobo zokusasaza eziphambili
Utyalo-mali kwizixhobo zokusasaza eziphambili kunokuphucula kakhulu inkqubo yokusasazwa kwaye kwandise ukusetyenziswa kwe-titanium dioxide. I-Speed-speed dispersers, i-bead mills, kunye ne-homogenizers ye-ultrasonic yimizekelo yezixhobo eziphambili ezinokusasaza ngokufanelekileyo iinqununu ze-TiO2, ngaloo ndlela ziphucula ukunikezelwa kombala, i-opacity, kunye nokuqina kwemveliso yokugqibela.
6. Ukuqhuba ulawulo lomgangatho kunye novavanyo
Ukuqinisekisa ukusasazwa okuhambelanayo kunye nokusebenzayo kwe-titanium dioxide, ulawulo olucokisekileyo lomgangatho kunye novavanyo kufuneka lwenziwe kuyo yonke inkqubo yokuvelisa. Oku kubandakanya ukubeka iliso ukusabalalisa ubungakanani bamasuntswana, ukuvavanya uphuhliso lombala, kunye nokuvavanya iimpawu ze-rheological zokusasazwa. Ngokuphumeza amanyathelo okulawula umgangatho oqinileyo, abavelisi banokuchonga kunye nokusombulula nayiphi na imiba enxulumene nokusabalalisa, ngaloo ndlela baphucula ukusebenza kwemveliso.
Isishwankathelo, ukwandisaizicelo titanium dioxideifuna ukuqwalaselwa ngononophelo kwinkqubo yokusasazwa. Ngokuqonda imigaqo yokusasazwa, ukukhetha indlela echanekileyo yokusasazwa, usebenzisa umgangatho ophezulu weemveliso ze-titanium dioxide, ukulungelelanisa iifomyula kunye neeparamitha zenkqubo, usebenzisa izixhobo zokusasazeka eziphambili, kunye nokulawula umgangatho ongqongqo, abavelisi banokufezekisa ukusasazwa okusebenzayo kwaye bakhulule amandla apheleleyo e-titanium. idayoksayidi. I-sulphur dioxide enokubakho kwiimveliso zabo. Ukusabalalisa okusebenzayo akuphuculi kuphela ukusebenza kwe-titanium dioxide, kodwa kunceda ekuphuculeni umgangatho jikelele kunye nokusebenza kwemveliso yokugqibela kuwo wonke amashishini.
