Surface jiyya na inorganic pigments

Bayan da surface jiyya na inorganic pigments, aikace-aikace yi na pigments za a iya kara inganta , da kuma sakamakon cikakken nuna ta Tantancewar Properties, shi ne daya daga cikin manyan matakan inganta ingancin sa na pigments.

Matsayin magani na saman

Za a iya taƙaita tasirin maganin saman zuwa cikin abubuwa uku masu zuwa:

1. don inganta kaddarorin pigment kanta, kamar ikon canza launi da ikon ɓoyewa;
2.  inganta aiki, da kuma inganta dispersibility da rarraba kwanciyar hankali na pigment a cikin wani ƙarfi da guduro;
3.  inganta pigment karshe kaya karko, sinadaran kwanciyar hankali da kuma processability.

Ana iya yin jiyya ta fuskar pigment ta hanyar rigar inorganic kuma ƙara abubuwan da ke aiki a saman don cimma abin ta, misali:

Chrome rawaya kumbura sauƙi a cikin masana'antu tsari, to thicken lokacin da toner yiwuwa ga "siliki", ta ƙara zinc sabulu, aluminum phosphate, aluminum hydroxide don rage m acicular lu'ulu'u, ƙananan kumburi sabon abu; gubar chrome yellow pigments za a iya amfani da antimony fili ko kasa mai wuya ko silica surface bi da inganta ta haske juriya, zafi juriya da sinadaran kwanciyar hankali; cadmium yellow surface area za a iya ƙara ta hanyar SiO2, Al2O3 surface jiyya, don inganta yanayin juriya, kuma za a iya kara sodium stearate, alkyl sulfonates, da dai sauransu zuwa surface daga hydrophilic zuwa lipophilic kuma mafi sauƙi tarwatsa a cikin guduro;

Cadmium ja ta Al2O3, SiO2 mai rufi jiyya na iya inganta dispersibility da yanayin juriya;
Iron oxide pigment na iya zama saman bi da tare da stearic acid wakili don inganta dispersibility a cikin wani kwayoyin halitta, da surface jiyya kuma iya zama Al2O3 , oleophilic surface don bunkasa yi;

M yellow baƙin ƙarfe oxide, zai iya inganta dispersibility da kuma nuna gaskiya ta ƙara sodium dodecyl naphthalene surface jiyya;

Iron blue pigments matalauta alkali juriya, alkali juriya za a iya inganta ta m amine surface jiyya;
Ultramarine matalauta acid juriya, acid iya inganta ta yi ta SiO2 surface jiyya;
Lithopone Lithopone a cikin zinc sulfide za a iya rage shi ta hanyar aikin photochemical na abubuwan da ba kasafai ba a cikin jiyya na sama.
