Ha leseli le sebetsa lihlahisoa tsa polasetiki, karolo e 'ngoe ea leseli e bonahala ho tloha holim'a sehlahisoa ho hlahisa khanya,' me karolo e 'ngoe ea leseli e khelosoa ebe e fetisetsoa ka hare ho polasetiki.Ha u kopana le likaroloana tsa pigment, ho bonahatsa, refraction le phetisetso li etsahala hape, 'me' mala o bontšitsoeng ke pigment.Mmala o bonahatsoang ke likaroloana.
Mekhoa ea mebala ea polasetiki e sebelisoang ka tloaelo ke: mebala e omileng, peista colorant (peista ea mebala) mebala, mebala ea masterbatch ea mebala.
1. 'Mala o omileng
Mokhoa oa ho sebelisa toner ka kotloloho (li-pigments kapa dae) ho eketsa palo e loketseng ea li-additives tsa phofo le lisebelisoa tse tala tsa polasetiki bakeng sa ho kopanya le ho kenya mebala ho bitsoa ho omisa coloring.
Melemo ea 'mala o omileng ke dispersibility e ntle le litšenyehelo tse tlase.E ka hlalosoa ka mokhoa o ikhethileng ho latela litlhoko, 'me ho itokisa ho bonolo haholo.E boloka tšebeliso ea basebetsi le lisebelisoa tsa thepa ha ho etsoa li-colorants tse kang li-masterbatches tsa mebala le li-pastes tsa mebala, kahoo theko e tlaase, 'me bareki le barekisi ha ba hloke ho e sebelisa.E thibetsoe ke palo: Bobebe ke hore pigment e tla ba le lerōle le fofang le tšilafalo nakong ea lipalangoang, polokelo, boima le ho kopanya, tse tla ama tikoloho ea mosebetsi le bophelo bo botle ba basebetsi.
2. Beha mebala ea mebala (peista ea mebala).
Mokhoa oa ho peista mebala, hangata colorant e tsoakoa le mokelikeli oa mokelikeli (plasticizer kapa resin) ho etsa pente, ebe e tsoakoa ka ho lekana le polasetiki, joalo ka pente ea 'mala bakeng sa sekhomaretsi sa tsoekere, pente, joalo-joalo.
Monyetla oa mebala ea pasty colorant (peista ea mebala) ke hore phello ea ho hasana e ntle, 'me tšilafalo ea lerōle e ke ke ea thehoa;bothata ke hore palo ea colorant ha e bonolo ho e bala 'me litšenyehelo li phahame.
3. Masterbatch coloring
Ha ho lokisoa masterbatch ea mebala, pigment ea mebala e tšoanelehang hangata e lokisoa pele, ebe pigment e tsoakoa ka har'a mochini oa masterbatch oa mebala ho latela tekanyo ea foromo.Likaroloana li kopantsoe ka botlalo, ebe li etsoa likaroloana tse lekanang ka boholo le likaroloana tsa resin, ebe li sebelisoa bakeng sa lisebelisoa tsa ho bōpa ho etsa lihlahisoa tsa polasetiki.Ha e sebelisoa, ke karolo e nyane feela (1% ho isa ho 4%) e lokelang ho eketsoa ho resin e mebala ho fihlela sepheo sa ho taka.
