Chithandizo chapamwamba cha inorganic pigments

Pambuyo pa mankhwala amtundu wa inorganic pigments, ntchito ya inki imatha kupitilizidwanso bwino, ndipo zotsatira zake zimawonetsa mawonekedwe ake owoneka bwino, ndicho chimodzi mwazinthu zazikulu zopititsira patsogolo mtundu wa pigment.

Udindo wa mankhwala pamwamba

Zotsatira za chithandizo chapamwamba zitha kufotokozedwa mwachidule m'magawo atatu awa:

1. kusintha katundu wa pigment palokha, monga mitundu mphamvu ndi kubisala mphamvu;
2.  kusintha ntchito, ndi kumapangitsanso dispersibility ndi kupezeka bata la pigment mu zosungunulira ndi utomoni;
3.  kusintha pigment komaliza katundu durability, mankhwala bata ndi processability.

Kuchiza pamwamba pa pigment kumatha kuchitidwa ndi malaya a inorganic ndikuwonjezera organic kuti akwaniritse zomwe akufuna, mwachitsanzo:

Chikaso cha chromium chimatupa mosavuta popanga, kukhuthala pamene tona imakhala "silika", powonjezera sopo za zinki, aluminium phosphate, aluminiyamu hydroxide kuti muchepetse makristalo owoneka bwino, kutsika kotupa; lead chrome yellow pigments angagwiritsidwe ntchito antimoni pawiri kapena osowa nthaka kapena silika pamwamba mankhwala kuti kusintha kuwala kwake, kukana kutentha ndi bata mankhwala; cadmium yellow pamwamba m'dera akhoza ziwonjezeke kudzera SiO2, Al2O3 mankhwala pamwamba, kumapangitsanso kukana nyengo, angathe kuwonjezeredwa sodium stearate, alkyl sulfonates, etc. kumtunda kuchokera hydrophilic kuti lipophilic ndi mosavuta omwazika mu utomoni;

Cadmium wofiira ndi Al2O3, SiO2 yokutidwa pamwamba mankhwala angathandizenso dispersibility ake ndi kukana nyengo;
Iron okusayidi pigment akhoza pamwamba ankachitira ndi stearic asidi wothandizila kusintha dispersibility mu sing'anga organic, mankhwala pamwamba angakhalenso Al2O3, oleophilic pamwamba kumapangitsanso ntchito;

Transparent yellow chitsulo okusayidi, akhoza kusintha dispersibility ndi kuwonekera powonjezera sodium dodecyl naphthalene pamwamba mankhwala;

Iron blue pigments osauka kukana kwa alkali, kukana kwa alkali kumatha kulimbikitsidwa ndi mafuta ake amine pamwamba pa mankhwala;
Ultramarine osauka asidi kukana, asidi akhoza kusintha ntchito yake ndi SiO2 pamwamba mankhwala;
Lithopone Lithopone mu nthaka sulfide akhoza kuchepetsedwa ndi photochemical ntchito ya osowa lapansi zinthu padziko mankhwala.
