I-Hue, ukukhanya, kunye nokugcwala zizinto ezintathu zombala, kodwa akwanelanga ukukhethaumbala weplastikis kuphela ngokusekelwe kwizinto ezithathu zombala.Ngokuqhelekileyo njengombala weplastiki, amandla ayo okuthambisa, amandla okufihla, ukuxhathisa ubushushu, ukuxhathisa ukufuduka, ukuxhathisa imozulu, ukuxhathisa ukunyibilika kunye nezinye iimpawu kufuneka ziqwalaselwe, kunye nokusebenzisana kwemibala kunye neepolima okanye izongezo.
(1) Ubuchule bokufaka imibala obunamandla
Amandla e-tinting yombala abhekiselele kubungakanani bombala ofunekayo ukufumana imveliso ethile yombala, echazwa njengepesenti yamandla okuthambisa wesampulu eqhelekileyo, kwaye inxulumene neempawu zebala kunye nokusasazwa kwayo.Xa ukhetha umbala, kuyafuneka ngokubanzi ukuba ukhethe umbala oqinileyo wokuthambisa ukuze unciphise inani lombala.
(2) Amandla anamandla okugquma.
Amandla okufihla anamandla abhekisa kubuchule be-pigment ukugquma umbala ongasemva wento xa isetyenziswa kumphezulu wento.Amandla okufihla angabonakaliswa ngokwamanani kwaye alingana nobunzima bepigment (g) efunekayo kwindawo nganye yomphezulu weyunithi xa umbala ongasemva ugqunywe ngokupheleleyo.Ngokubanzi, ii-pigments ze-inorganic zinamandla okugquma awomeleleyo, ngelixa ii-organic pigments ziselubala kwaye zingenawo amandla okugquma, kodwa zinokuba namandla okugquma xa zisetyenziswa kunye ne-titanium dioxide.
(3) Ukumelana nobushushu obuhle.
Ukumelana nobushushu kwee-pigments kubhekiselele ekutshintsheni kombala okanye kwiipropathi zee-pigments kumaqondo okushisa.Ngokuqhelekileyo, ixesha lokumelana nobushushu be-pigment lifuneka ukuba libe yi-4 ~ 10min.Ngokubanzi, ii-pigments ze-inorganic ziyakwazi ukumelana nobushushu kwaye akukho lula ukubola kumaqondo obushushu obuseplastikini, ngelixa i-organic pigments inokumelana nobushushu.
(4) Ukuchasana nokufuduka okulungileyo.
Ukufuduka kwe-pigment kubhekiselele kwinto yokuba iimveliso zeplastiki ezinemibala zihlala zidibana nezinye izinto eziqinileyo, ulwelo, iigesi kunye nezinye izinto, kwaye i-pigments ifuduka isuka ngaphakathi kwiplastiki iye kumphezulu okhululekileyo wemveliso okanye izinto ezidibana nayo.Ukufuduka kwemibala kwiiplastiki kubonisa ukungahambelani kakubi phakathi kwemibala kunye neerasi.Ngokubanzi, ii-pigments kunye ne-organic pigments zinobumanzi obuphezulu, ngelixa i-inorganic pigments inobumanzi obuphantsi.
(5) Ukumelana nokukhanya okulungileyo kunye nokumelana nemozulu.
Ukukhanya kunye nokuqina kwemozulu kubhekiselele ekuzinzeni kombala phantsi kokukhanya kunye neemeko zendalo.Ukukhawuleza kokukhanya kuhambelana nesakhiwo semolekyuli yombala.Imibala eyahlukeneyo inezakhiwo ezahlukeneyo zeemolekyuli kunye nokukhanya okulula.
(6) Ukuxhathisa okulungileyo kwe-asidi, ukuxhathisa kwe-alkali, ukuxhathisa i-solvent kunye nokumelana nemichiza.
Iimveliso zeplastiki zoshishino zihlala zisetyenziselwa ukugcina iikhemikhali kunye neekhemikhali zokuthutha ezifana ne-acids kunye ne-alkali, ngoko ke ukuxhathisa kwe-asidi kunye ne-alkali ye-pigments kufuneka kuthathelwe ingqalelo.
