Okwekenenya ensibuko ya langi za langi:
The paint pigment makes the film present color, so that the film has the ability to cover the object to be coated, so as to play its decorative and protective role. Some pigments can also provide such properties as improving the mechanical properties of paint film, improving the durability of paint film, providing anti-corrosion, conductive, flame retardant and so on. Pigments can be divided into natural pigments and synthetic pigments according to their sources, inorganic pigments and organic langi okusinziira ku bikozesebwa byabwe eby’eddagala, n’embala ezikuba langi, langi za ssemateeka ne langi ez’enjawulo okusinziira ku mirimu gyabyo mu kusiiga .
Mu nnaku ezaasooka, amafuta g'enva endiirwa ge gaali agasinga okuba ag'okusiiga langi, kale nga gayitibwa "erangi za langi", gamba ng'obulamu n'okukuuma obutonde bw'ensi mu bitonde eby'omu ttaka ebyasooka eby'obutonde. byombi ebizigo eby'ekinnansi n'ebintu eby'obutonde ng'ebintu ebisookerwako n'ebintu eby'omulembe eby'okusiiga n'ebintu ebikolebwa mu butonde nga bikolebwa mu birungo eby'obutonde eby'ebintu eby'omulembe eby'eddagala, ne firimu ezikolebwa mu kusiiga ebirungo ebiva mu kirungo kya polimeliti { 1} bibeera mu bikozesebwa eby'omulembe, ne firimu ezikolebwa mu ngeri ey'obutonde (Cascilisel) nga zisiigibwa ebirungo ebiva mu birungo eby'omulembe (organic chemical polymer, ne firimu ezikoleddwa Products. Ebizigo eby’omulembe bigenda bifuuka ekika ky’ebintu bya yinginiya ebikola emirimu mingi, nga guno gwe mulimu omukulu mu makolero g’eddagala .
Olw’okuba mu bbanga erimu ery’obunene bw’obutundutundu, langi gy’ekoma okuba ennungi, amaanyi gaayo ag’okubikka n’amaanyi g’okubikka gye bikoma okuba eby’amaanyi, bwe kityo eddoboozi eddene n’okumasamasa kwa langi birongoosebwa. okutondebwa kw’ebigatta bikwatagana n’embeera z’enkuba, nga {1} nga ekirungo ekisookerwako eky’ebisengekera, pH value of solution, reaction time, reaction temperature and calcine temperature .
