Awọn pigments ti a lo ninu masterbatch awọ gbọdọ san ifojusi si ibatan ibaramu laarin awọn awọ, awọn ohun elo aise ṣiṣu ati awọn afikun.Awọn aaye yiyan jẹ bi atẹle:
(1) Pigments ko le fesi pẹlu resins ati orisirisi additives, ati ki o ni lagbara epo resistance, kekere ijira, ati ki o dara ooru resistance.Iyẹn ni lati sọ, masterbatch ko le kopa ninu ọpọlọpọ awọn aati kemikali.Fun apẹẹrẹ, dudu erogba le ṣakoso iṣesi imularada ti ṣiṣu polyester, nitorinaa ohun elo dudu erogba ko le ṣafikun polyester.Nitori iwọn otutu idọti giga ti awọn ọja ṣiṣu, pigmenti ko yẹ ki o decompose ati discolor ni iwọn otutu alapapo mimu.Ni gbogbogbo, awọn pigments inorganic ni resistance ooru to dara julọ, lakoko ti awọn pigments Organic ati awọn awọ ko ni itọju ooru ti ko dara, eyiti o yẹ ki o san akiyesi to nigbati o yan awọn oriṣiriṣi awọ.
(2) Awọn dispersibility ati tinting agbara ti awọn pigmenti ni o wa dara.Pipin aiṣedeede ti pigmenti yoo ni ipa lori hihan ọja naa;agbara tinting ti ko dara ti pigmenti yoo yorisi ilosoke ninu iye pigmenti ati ilosoke ninu iye owo ohun elo.Iyatọ ati agbara tinting ti pigmenti kanna ni orisirisi awọn resins kii ṣe kanna, nitorina eyi yẹ ki o san ifojusi si nigbati o yan awọn awọ.Awọn dispersibility ti pigmenti jẹ tun jẹmọ si awọn patiku iwọn.Awọn kere awọn patiku iwọn ti awọn pigmenti, awọn dara awọn dispersibility ati awọn ni okun awọn tinting agbara.
(3) Loye miiran-ini ti pigments.Fun apẹẹrẹ, fun awọn ọja ṣiṣu ti a lo ninu ounjẹ ati awọn ohun-iṣere ọmọde, awọn awọ ni a nilo lati jẹ ti kii ṣe majele;fun awọn ọja ṣiṣu ti a lo ninu awọn ohun elo itanna, awọn pigments pẹlu idabobo itanna to dara yẹ ki o yan;fun lilo ita Fun awọn ọja ṣiṣu, awọn pigments pẹlu resistance oju ojo to dara yẹ ki o yan.
