I-Titanium Dioxide
I-Titanium dioxide iyi-pigment emhlophe ye-inorganic, ingxenye eyinhloko yi-TiO2.
Ngenxa yezakhiwo zayo ezizinzile zomzimba namakhemikhali, ukusebenza okuhle kakhulu kwe-optical kanye ne-pigment, kubhekwa njengebala elimhlophe elingcono kakhulu emhlabeni. Isetshenziswa kakhulu emikhakheni eminingi efana nezingubo zokugqoka, ukwenza amaphepha, izimonyo, i-electronics, izitsha zobumba, imithi kanye nezithasiselo zokudla. Ukusetshenziswa kwemali ngayinye ye-titanium dioxide kuthathwa njengenkomba ebalulekile yokukala izinga lokuthuthuka komnotho wezwe.
Njengamanje, inqubo yokukhiqizwa kwe-titanium dioxide e-China ihlukaniswe ngendlela ye-sulfuric acid, indlela ye-chloride kanye nendlela ye-hydrochloric acid.
Izigqoko
I-Sun Bang izibophezele ekuhlinzekeni i-titanium dioxide yekhwalithi ephezulu embonini yokuhlanganisa. I-Titanium dioxide ingenye yezingxenye ezibalulekile ekukhiqizeni okunamathelayo. Ngaphezu kokumboza nokuhlobisa, indima ye-titanium dioxide iwukuthuthukisa izakhiwo ezingokomzimba nezamakhemikhali zokumboza, ukuthuthukisa ukuqina kwamakhemikhali, ukuthuthukisa amandla emishini, ukunamathela nokungagqwali kwesicelo. I-Titanium dioxide nayo ingathuthukisa ukuvikelwa kwe-UV nokungena kwamanzi, futhi ivimbele imifantu, ibambezele ukuguga, yelule impilo yefilimu kapende, ukumelana nokukhanya nesimo sezulu; ngesikhathi esifanayo, i-titanium dioxide nayo ingasindisa izinto futhi yandise izinhlobo.
Ipulasitiki Nerabha
Ipulasitiki iyimakethe yesibili ngobukhulu ye-titanium dioxide ngemuva kokumbozwa.
Ukusetshenziswa kwe-titanium dioxide emikhiqizweni yepulasitiki ukusebenzisa amandla ayo okucasha aphezulu, amandla aphezulu okukhipha umbala nezinye izici ze-pigment. I-Titanium dioxide ingaphinde ithuthukise ukumelana nokushisa, ukumelana nokukhanya kanye nokumelana nesimo sezulu semikhiqizo yepulasitiki, futhi ivikele ngisho nemikhiqizo yepulasitiki ekukhanyeni kwe-ultraviolet ukuze ithuthukise izakhiwo zemishini nezikagesi zemikhiqizo yepulasitiki. Ukuhlakazeka kwe-titanium dioxide kunokubaluleka okukhulu emandleni ombala epulasitiki.
Uyinki & Ukuphrinta
Njengoba uyinki mncane kunopende, uyinki unezidingo eziphakeme ze-titanium dioxide kunopende. I-titanium dioxide yethu inosayizi wezinhlayiyana ezincane, ukusatshalaliswa okufanayo kanye nokuhlakazeka okuphezulu, ukuze uyinki ukwazi ukuzuza amandla aphezulu okucasha, amandla okuthayela aphezulu kanye nesicwebezelisi esiphezulu.
Ukwenza amaphepha
Embonini yesimanje, imikhiqizo yephepha njengendlela yokukhiqiza, engaphezu kwengxenye esetshenziselwa izinto zokunyathelisa. Ukukhiqizwa kwephepha kuyadingeka ukuze kunikeze ukukhanya okukhanyayo nokukhanya okuphezulu, futhi kunamandla anamandla okuhlakaza ukukhanya. I-Titanium dioxide iyi-pigment engcono kakhulu yokuxazulula ukungafihli ekukhiqizeni iphepha ngenxa yenkomba yayo engcono kakhulu yokuphinda i-refractive kanye ne-light scattering index. Iphepha elisebenzisa i-titanium dioxide linobumhlophe obuhle, amandla aphezulu, licwebezela, lincane futhi libushelelezi, futhi alingeni lapho liphrintwa. Ngaphansi kwezimo ezifanayo, i-opacity iphindwe izikhathi ezingu-10 kune-calcium carbonate ne-talcum powder, futhi ikhwalithi nayo ingancishiswa ngo-15-30%.
