Emkhakheni wesayensi yezinto zokwakha, i-titanium dioxide (TiO2) iyinhlanganisela esetshenziswa kabanzi enezinhlobo ezintathu zekristalu eziyinhloko: i-anatase, i-rutile ne-brookite. Ifomu ngalinye linezakhiwo ezihlukile ezilenza lifaneleke ezinhlobonhlobo zezicelo zezimboni. Phakathi kwabo, i-rutile titanium dioxide idonsele ukunakwa okukhulu, ikakhulukazi embonini yeyinki yokunyathelisa, lapho izakhiwo zayo zingathinta kakhulu izinga nokuqina kwezinto eziphrintiwe.
I-Rutile iwuhlobo oluzinzile noluchichima kakhulu lwe-titanium dioxide, enenkomba ye-refractive ephezulu kanye ne-opacity enhle kakhulu. Lezi zakhiwo ziyenza ibe i-pigment efanelekile yokuphrinta oyinki njengoba ingathuthukisa ukugqama kombala futhi inikeze ukumbozwa okuhle kakhulu. I-KWR-659 eka-KWRrutile titanium dioxideekhiqizwa inqubo ye-sulfuric acid, ebonisa ukubaluleka kwezimboni zaleli fomu. Idizayinelwe ngokukhethekile imboni ye-inki yokunyathelisa, i-KWR-659 inikeza ukusebenza okuvelele ezinhlotsheni eziningi zezinhlelo zokusebenza, iqinisekisa ukuthi izinto eziphrintiwe azibukeki zinempilo kuphela, kodwa futhi zimelana nesikhathi.
I-morphology kaRutile iyenza isebenze kahle kakhulu ekuphrinteni iziyinki. Isakhiwo sayo sekristalu esifana nenaliti sivumela ukuhlakazeka okungcono kwemithombo ye-liquid, okuholela ekuthuthukisweni kokugeleza kanye nezakhiwo zesicelo. Lokhu kubaluleke kakhulu phakathi nenqubo yokunyathelisa, lapho ukuhambisana nekhwalithi kubaluleke kakhulu. Ukwakhiwa kwe-KWR-659 kuqinisekisa ukuthi ihlangabezana nezidingo eziqinile zemboni yokunyathelisa, ihlinzeka ngesixazululo esithembekile kubakhiqizi abafuna oyinki bekhwalithi ephezulu.
Ngokungqubuzanayo,i-rutile anatase ne-brookite, kuyilapho futhi izinhlobo ze-titanium dioxide, zinezici ezihlukahlukene ezingase zinciphise ukusetshenziswa kwazo kwezinye izinhlelo zokusebenza. Isibonelo, i-anatase yaziwa ngezici zayo ze-photocatalytic, okuyenza ifanelekele izinhlelo zokusebenza zokulungisa imvelo kanye nezindawo zokuzihlanza. Kodwa-ke, ukuzinza kwayo okuphansi uma kuqhathaniswa ne-rutile kungabangela izinkinga ezinhlelweni zesikhathi eside, njengeziyinki zokuphrinta, lapho ukuqina kubalulekile. I-Brookite iyindlela engavamile kakhulu, evame ukusibekela abazala bayo abadume kakhulu futhi ayisetshenziswa kancane ezinhlelweni zezimboni.
I-KWR-659 yinkampani ehamba phambili ekukhiqizeni i-sulfuric acid titanium dioxide, isebenzisa ubuchwepheshe benqubo ethuthukisiwe kanye nemishini yokukhiqiza esezingeni lokuqala ukukhiqiza imikhiqizo esezingeni eliphezulu njenge-KWR-659. Ukuzibophezela kwenkampani kwikhwalithi yomkhiqizo nokuvikelwa kwemvelo kubonakala enqubweni yayo yokukhiqiza, ebeka phambili ukusimama ngaphandle kokubeka engcupheni ukusebenza. Lokhu kuzinikela akwenzi nje ukuthi i-KWR-659 ibe umholi wemboni, kodwa futhi kuhlangabezana nesidingo esikhulayo semikhiqizo ehambisana nemvelo embonini yeyinki yokunyathelisa.
Ukubaluleka kwemboni ye-titanium dioxide, ikakhulukazi i-rutile titanium dioxide, akunakubukelwa phansi. Njengoba imboni iqhubeka nokuthuthuka, isidingo sezinto ezisebenza kahle ezihlangabezana nezindinganiso eziqinile zekhwalithi sizokhula kuphela. I-KWR-659 ibonisa amandla e-rutile titanium dioxide ukuthuthukisa ikhwalithi yoyinki wokuphrinta, inikeze abakhiqizi isisombululo esinokwethenjelwa nesisebenzayo.
Kafushane, ukuqonda i-morphologies ye-anatase, i-rutile, ne-brookite kubalulekile ekuqondeni ukubaluleka kwazo kwemboni. I-Rutile idlala indima ebalulekile embonini ye-inki yokunyathelisa ngenxa yezindawo zayo ezihamba phambili, futhi imikhiqizo efana ne-KWR-659 evela ku-KW iyizibonelo zentuthuko kulo mkhakha. Njengoba siqhubekela phambili, ukuhlola okuqhubekayo kwamandla e-titanium dioxide ngokungangabazeki kuzoholela ekuthuthukisweni okusha nasekuthuthukisweni kwezinhlobonhlobo zezinhlelo zokusebenza zezimboni.
