Hue, lightness le saturation ke likarolo tse tharo tsa 'mala, empa ha hoa lekana ho khethapolasetiki ea mmalas feela e thehiloe holim'a likarolo tse tharo tsa 'mala.Hangata e le 'mala oa polasetiki, matla a eona a ho pata, matla a ho pata, ho hanyetsa mocheso, ho hanyetsa ho falla, ho hanyetsa boemo ba leholimo, khanyetso ea solvent le thepa e meng e lokela ho nkoa hape, hammoho le ho sebelisana ha mebala le li-polymers kapa li-additives.
(1) Bokhoni bo matla ba ho kenya mebala
Colour tinting power e bolela palo ya pigment e hlokehang ho fumana sehlahiswa se itseng sa mmala, se hlahiswang e le peresente ya matla a tinting a sampole e tlwaelehileng, mme a amana le thepa ya pigment le ho hasana ha yona.Ha u khetha colorant, hangata ho hlokahala hore u khethe 'mala o nang le matla a matla a ho penya ho fokotsa boholo ba' mala.
(2) Matla a matla a ho koahela.
Matla a matla a ho pata a bolela bokhoni ba 'mala ho koahela bokamorao ba 'mala oa ntho ha e sebelisoa bokaholimo ba ntho.Matla a ho ipata a ka hlalosoa ka lipalo 'me a lekana le boima ba pigment (g) e hlokahalang sebakeng se seng le se seng ha 'mala o ka morao o koahetsoe ka ho feletseng.Ka kakaretso, li-pigment tsa inorganic li na le matla a matla a ho koahela, athe mebala ea tlhaho e bonaletsa ebile ha e na matla a ho koahela, empa a ka ba le matla a ho koahela ha a sebelisoa hammoho le titanium dioxide.
(3) Ho hanyetsa mocheso o motle.
Ho hanyetsa mocheso oa li-pigments ho bolela ho fetoha ha 'mala kapa thepa ea li-pigments ka mocheso oa ho sebetsa.Ka kakaretso, nako ea ho hanyetsa mocheso ea pigment e hlokahala hore e be 4 ~ 10min.Ka kakaretso, li-pigment tsa inorganic li na le matla a ho hanyetsa mocheso 'me ha li bonolo ho bola ha mocheso oa polasetiki o sebetsa, ha li-pigment tsa tlhaho li na le mocheso o fokolang.
(4) Khanyetso e ntle ea ho falla.
Ho falla ha pigment ho bolela ketsahalo ea hore lihlahisoa tsa polasetiki tse mebala li atisa ho kopana le lintho tse ling tse tiileng, metsi, likhase le lintho tse ling, 'me li-pigments li tloha ka hare ho polasetiki ho ea sebakeng se sa lefelloeng sa sehlahisoa kapa lintho tse amanang le eona.Ho falla ha li-colorants ka li-plastiki ho bontša ho se lumellane ho fokolang pakeng tsa mebala le li-resin.Ka kakaretso, li-pigment le li-organic pigments li na le metsi a mangata, athe li-pigment tsa inorganic li na le metsi a fokolang.
(5) Ho hanyetsa khanya e ntle le ho hanyetsa boemo ba leholimo.
Lightfastness le weatherability li bolela botsitso ba mebala tlas'a khanya le maemo a tlhaho.Ho potlaka ha leseli ho amana le sebopeho sa limolek'hule tsa colorant.Li-colorants tse fapaneng li na le libopeho tse fapaneng tsa limolek'hule le bobebe.
(6) Ho hanyetsa acid e ntle, khanyetso ea alkali, khanyetso ea solvent le khanyetso ea lik'hemik'hale.
Lihlahisoa tsa polasetiki tsa indasteri li atisa ho sebelisoa ho boloka lik'hemik'hale le ho tsamaisa lik'hemik'hale tse kang li-acids le alkalis, kahoo ho hanyetsa acid le alkali ea li-pigments ho lokela ho nkoa.
