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 ho kopana le likaroloana tsa pigment, ho bonahatsa, refraction le phetisetso li etsahala hape, 'me 'mala o bontšitsoeng ke likaroloana tsa pigment.Mmala o bonahaditsweng.
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 kopanya le ho kenya mebala ka ho toba le toner (li-pigments kapa dae) ho eketsa palo e loketseng ea li-additives tsa phofo le lisebelisoa tse tala tsa polasetiki ho bitsoa ho omisa mebala.
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 lekanyelitsoe ke chelete;bothata ke hore pigment e tla fofa lerōle 'me e baka 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).
Mokhoeng oa ho peista, colorant hangata e tsoakoa le mokelikeli oa mokelikeli (plasticizer kapa resin) ebe e siloa ka pente, ebe e tsoakoa ka ho lekana le polasetiki, joalo ka pente ea mebala bakeng sa enamel, pente, jj.
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 li-masterbatches tsa mebala, li-pigments tse tšoanelehang tsa mebala hangata li lokisoa pele, ebe li-pigments li kopantsoe ka har'a mochini oa masterbatch oa mebala ho latela tekanyo ea foromo.Limolek'hule li kopantsoe ka ho feletseng, ebe li etsoa likaroloana tse lekanang ka boholo le likaroloana tsa resin, tse sebelisoang ke thepa ea ho bōpa ho etsa lihlahisoa tsa polasetiki.Ha e sebelisoa, ke karolo e nyane feela (1% ~ 4%) e lokelang ho eketsoa ho resin e mebala ho fihlela sepheo sa ho taka.
Ha ho bapisoa le mebala e omileng, masterbatch coloring e na le melemo e latelang e totobetseng: ho ntlafatsa tšilafalo ea tikoloho e bakoang ke ho fofa ha toner, ho fetola 'mala o bonolo nakong ea tšebeliso, ha ho na ho hloekisa ho khethehileng ha extruder hopper, le foromo e tsitsitseng E na le ts'ebetso e matla' me e ka etsa bonnete ba hore 'mala oa li-extruder hopper. lihlopha tse peli tsa li-masterbatches tsa mebala tsa mofuta o le mong li lula li tsitsitse.Bobebe ba 'mala oa masterbatch ke hore litšenyehelo tsa ho kenya mebala li holimo' me palo ea litokisetso ha e fetohe.Ntle le moo, lithane tsa pearlescent, phofo ea fluorescent, phofo e khanyang le lithane tse ling li entsoe ka li-masterbatches tsa mebala ebe li sebelisoa ho etsa mebala ea polasetiki.Ha ho bapisoa le li-plastiki tse kopanyang ka ho toba bakeng sa mebala, phello (e kang gloss, joalo-joalo) e fokolloa ke hoo e ka bang 10%, 'me lihlahisoa tsa ho bopa ente le tsona li atisa ho phalla mela.Methapo le seams.
