I-Hue, ukukhanya, nokugcwaliswa kwesikhala yizici ezintathu zombala, kodwa akwanele ukukhethaumbala wepulasitikis kuphela ngokusekelwe ezintweni ezintathu zombala.Imvamisa njengombala wepulasitiki, amandla awo okuthayela, amandla okufihla, ukumelana nokushisa, ukumelana nokufuduka, ukumelana nesimo sezulu, ukumelana ne-solvent nezinye izakhiwo kufanele kucatshangelwe, kanye nokusebenzelana kombala nama-polymers noma izithasiselo.
(1) Ikhono elinamandla lokufaka imibala
Amandla e-colorant tinting abhekisela enanini le-pigment edingekayo ukuze kutholwe umkhiqizo othile wombala, ovezwa njengephesenti lamandla okuthayela esampula elijwayelekile, futhi ahlobene nezakhiwo ze-pigment nokuhlakazwa kwayo.Lapho ukhetha umbala, ngokuvamile kuyadingeka ukuthi ukhethe umbala onamandla okuthayela aqinile ukuze unciphise inani lombala.
(2) Amandla okusibekela aqinile.
Amandla okufihla aqinile asho ikhono le-pigment ukumboza umbala ongemuva wento lapho usetshenziswa endaweni engaphezulu yento.Amandla okufihla angavezwa ngezinombolo futhi alingana nesisindo sombala (g) esidingekayo endaweni ngayinye yendawo lapho umbala ongemuva umbozwe ngokuphelele.Ngokuvamile, izingulube ze-inorganic zinamandla okuvala aqinile, kuyilapho izingulube zemvelo zisobala futhi azinawo amandla okuvala, kodwa zingaba namandla okuvala uma zisetshenziswa kanye ne-titanium dioxide.
(3) Ukumelana nokushisa okuhle.
Ukumelana nokushisa kwezingulube kubhekisela ekushintsheni kombala noma izakhiwo ze-pigments emazingeni okushisa okucubungula.Ngokuvamile, isikhathi sokumelana nokushisa kwe-pigment sidingeka sibe yi-4 ~ 10min.Ngokuvamile, i-pigments ye-inorganic inokumelana kahle nokushisa futhi akulula ukubola emazingeni okushisa okucubungula epulasitiki, kuyilapho i-organic pigments inokumelana nokushisa okuphansi.
(4) Ukumelana kahle nokufuduka.
Ukufuduka kwe-pigment kubhekisela esenzakalweni sokuthi imikhiqizo yepulasitiki enombala ivamise ukuthintana nezinye izinto eziqinile, uketshezi, amagesi nezinye izinto, futhi i-pigment isuka ngaphakathi kwepulasitiki iye endaweni ekhululekile yomkhiqizo noma izinto ezithintana nayo.Ukufuduka kombala kumapulasitiki kubonisa ukungahambisani kahle phakathi kwama-colorants nama-resin.Imvamisa, i-pigments ne-organic pigments inoketshezi oluningi, kuyilapho i-inorganic pigments inoketshezi oluphansi.
(5) Ukumelana nokukhanya okuhle nokumelana nesimo sezulu.
Ukukhanya okulula kanye nesimo sezulu kubhekisela ekuzinzeni kombala ngaphansi kwezimo zokukhanya nezemvelo.Ukushesha kokukhanya kuhlobene nesakhiwo samangqamuzana sombala.Ama-colorants ahlukene anezakhiwo zamangqamuzana ahlukene kanye nokukhanya okulula.
(6) Ukumelana ne-asidi okuhle, ukumelana ne-alkali, ukumelana ne-solvent kanye nokumelana namakhemikhali.
Imikhiqizo yepulasitiki yezimboni ivame ukusetshenziselwa ukugcina amakhemikhali kanye nokuthutha amakhemikhali afana nama-acids nama-alkali, ngakho-ke ukumelana ne-asidi ne-alkali ye-pigments kufanele kucatshangelwe.
