Titanium dioxide
I-Titanium Dioxide iyi-informent emhlophe, isakhi esiyinhloko yi-tio2.
Ngenxa yezakhiwo zayo ezizinzile zenyama nangamakhemikhali, ukusebenza okuhle kakhulu kwe-spiki kanye nombala, kubhekwa njenge-pigment emhlophe engcono kakhulu emhlabeni. Isetshenziswa kakhulu emikhakheni eminingi efana nokugqoka, ukwenza amaphepha, izimonyo, ama-elekthronikhi, ama-ceramics, umuthi kanye nezithasiselo zokudla. Ukusetshenziswa kwenhlokodolobha ngayinye ye-titanium dioxide kubhekwa njengenkomba ebalulekile ukukala izinga lokuthuthukiswa komnotho kwezwe.
Njengamanje, inqubo yokukhiqiza yeTitanium Dioxide eChina ihlukaniswe nge-Sulfuric Acid Way, I-Chloride indlela kanye ne-Hydrochloric acid indlela.
Ukumboza
ILanga Bang izibophezele ekuhlinzekeni i-Titanium Engaphezulu ye-Dioxide embonini ye-Coating. I-Titanium Dioxide ingenye yezinto ezisemqoka ekukhiqizweni kwezimbobo. Ngaphezu kokumboza kanye nomhlobiso, iqhaza le-Titanium Dioxide ukuthuthukisa izakhiwo zomzimba nangamakhemikhali zezimbali, thuthukisa ukuqina kwamakhemikhali, ukuthuthukisa amandla okuqina, ukunxusa kanye nokuphikiswa kokugqwala kwesicelo. I-Titanium Dioxide futhi ingathuthukisa ukuvikelwa kwe-UV nokungena kwamanzi, futhi ivikele ukuqhekeka, ukumbulala, ukwelula impilo yefilimu yokupenda, ukukhanya nokumelana nesimo sezulu; Ngasikhathi sinye, titanium dioxide nayo ingagcina izinto zokwakha futhi yandise izinhlobo.
Ipulasitiki nenjoloba
Ipulasitiki yimakethe yesibili ngobukhulu ye-titanium dioxide ngemuva kokuhlanganisa.
Ukusetshenziswa kwe-titanium dioxide emikhiqizweni yepulasitiki ukusebenzisa amandla ayo aphezulu aphezulu, amandla aphezulu ahlehlise kanye nezinye izakhiwo ze-pigment. I-Titanium dioxide ingathuthukisa nokumelana nokushisa, ukumelana nokukhanya kanye nokumelana nesimo sezulu kwemikhiqizo yepulasitiki, futhi kuvikeleke imikhiqizo yepulasitiki kusuka ekukhanyiseni kwe-ultraviolet ukuthuthukisa izakhiwo zemishini nezemikhiqizo yepulasitiki. Ukungabonakali kwe-titanium dioxide kunokubaluleka okukhulu emandleni okubala umbala.
Uyinki nokuphrinta
Njengoba inki incane kunopende, uyinki unezidingo eziphakeme ze-titanium dioxide kunopende. I-titanium dioxide yethu inosayizi omncane wezinhlayiyana, ukuhanjiswa okufanayo kanye nokuhlakazeka okuphezulu, ukuze uyinki ungafinyelela amandla aphezulu acashile, amandla aphezulu okugcotshwa kanye ne-gloss ephakeme.
Ukuphanga
Embonini yanamuhla, imikhiqizo yamaphepha njengendlela yokukhiqiza, ngaphezu kwengxenye yazo esetshenziselwa izinto zokuphrinta. Ukukhiqizwa kwephepha kuyadingeka ukuhlinzeka nge-opacity nokukhanya okuphezulu, futhi kunekhono elinamandla lokusakaza ukukhanya. I-Titanium Dioxide iyi-picment engcono kakhulu yokuxazulula i-opacity ekukhiqizeni amaphepha ngenxa yenkomba yayo ehle kakhulu ye-reuctive nenkomba yokusakazeka yokukhanya. Iphepha lisebenzisa i-titanium dioxide linomhlophe omuhle, amandla aphezulu, isicwebezelisi, elincanyana futhi libusheleleke, futhi lingangeni lapho liphrintiwe. Ngaphansi kwezimo ezifanayo, i-opacity iphakeme izikhathi eziyi-10 kune-calcium carbonate ne-talcum powder, futhi ikhwalithi nayo ingancishiswa ngo-15-30%.
