I-Titanium Dioxide
I-Titanium dioxide iyi-pigment emhlophe engakhiqizi izinto eziphilayo, ingxenye eyinhloko yi-TiO2.
Ngenxa yezakhiwo zayo zomzimba nezamakhemikhali ezizinzile, ukusebenza kwayo okuhle kakhulu kokukhanya kanye nombala, ibhekwa njengombala omhlophe ongcono kakhulu emhlabeni. Isetshenziswa kakhulu emikhakheni eminingi efana nokugqoka, ukwenza amaphepha, izimonyo, izinto zikagesi, izinto zobumba, imithi kanye nezithasiselo zokudla. Ukusetshenziswa kwe-titanium dioxide ngenhloko ngayinye kubhekwa njengesibonakaliso esibalulekile sokulinganisa izinga lentuthuko yezomnotho yezwe.
Njengamanje, inqubo yokukhiqizwa kwe-titanium dioxide eShayina ihlukaniswe phakathi indlela ye-sulfuric acid, indlela ye-chloride kanye nendlela ye-hydrochloric acid.
Ukugqoka
I-Sun Bang izibophezele ekuhlinzekeni i-titanium dioxide esezingeni eliphezulu embonini yokuhlanganisa. I-Titanium dioxide ingenye yezingxenye ezibalulekile ekukhiqizweni kokuhlanganisa. Ngaphezu kokumboza nokuhlobisa, indima ye-titanium dioxide ukuthuthukisa izakhiwo zomzimba nezamakhemikhali zokuhlanganisa, ukuthuthukisa ukuzinza kwamakhemikhali, ukuthuthukisa amandla okusebenza, ukunamathela kanye nokumelana nokugqwala kokusetshenziswa. I-Titanium dioxide ingathuthukisa nokuvikelwa kwe-UV kanye nokungena kwamanzi, futhi ivimbele imifantu, ibambezele ukuguga, yandise impilo yefilimu yopende, ukumelana nokukhanya nesimo sezulu; ngesikhathi esifanayo, i-titanium dioxide ingasindisa nezinto futhi yandise izinhlobo.
Ipulasitiki nerabha
Ipulasitiki iyimakethe yesibili ngobukhulu ye-titanium dioxide ngemuva kokumbozwa.
Ukusetshenziswa kwe-titanium dioxide emikhiqizweni yepulasitiki kusetshenziswa amandla ayo aphezulu okufihla, amandla aphezulu okususa umbala kanye nezinye izakhiwo zombala. I-titanium dioxide ingathuthukisa futhi ukumelana nokushisa, ukumelana nokukhanya kanye nokumelana nesimo sezulu kwemikhiqizo yepulasitiki, futhi ivikele ngisho nemikhiqizo yepulasitiki ekukhanyeni kwe-ultraviolet ukuze ithuthukise izakhiwo zemishini nezikagesi zemikhiqizo yepulasitiki. Ukuhlakazeka kwe-titanium dioxide kubaluleke kakhulu emandleni okufaka umbala epulasitiki.
Uyinki Nokuphrinta
Njengoba uyinki umncane kunopende, uyinki unezidingo eziphezulu ze-titanium dioxide kunopende. I-titanium dioxide yethu inosayizi omncane wezinhlayiya, ukusatshalaliswa okufanayo kanye nokusabalala okuphezulu, ukuze uyinki ikwazi ukuthola amandla aphezulu okufihla, amandla aphezulu okupenda kanye nokucwebezela okuphezulu.
Ukwenza amaphepha
Embonini yanamuhla, imikhiqizo yephepha njengendlela yokukhiqiza, okungaphezu kwengxenye yayo esetshenziselwa izinto zokunyathelisa. Ukukhiqizwa kwephepha kuyadingeka ukuze kuhlinzekwe ukufiphala nokukhanya okuphezulu, futhi kunekhono elinamandla lokusabalalisa ukukhanya. I-Titanium dioxide iyi-pigment engcono kakhulu yokuxazulula ukufiphala ekukhiqizweni kwephepha ngenxa ye-refractive index yayo engcono kakhulu kanye ne-light scattering index. Iphepha elisebenzisa i-titanium dioxide linobumhlophe obuhle, amandla aphezulu, licwebezela, lincane futhi libushelelezi, futhi alingeni lapho linyatheliswa. Ngaphansi kwezimo ezifanayo, ukufiphala kuphakeme ngokuphindwe kayishumi kune-calcium carbonate kanye ne-talcum powder, futhi ikhwalithi ingancishiswa ngo-15-30%.
