Hue, kureruka, uye saturation zvinhu zvitatu zveruvara, asi hazvina kukwana kusarudzaplastiki colorants chete yakavakirwa pazvinhu zvitatu zveruvara.Kazhinji seyepurasitiki colorant, simba rayo rekupenya, simba rekuhwanda, kupisa kupisa, kuramba kutama, kuramba kwemamiriro ekunze, kupikisa kunyungudika uye zvimwe zvinhu zvinofanirwa kutariswa, pamwe nekudyidzana kwemavara nemapolymers kana additives.
(1) Simba rekupenda mavara
Colourant tinting simba inoreva huwandu hwepigment inodiwa kuwana chimwe chigadzirwa cheruvara, chinotaridzwa sechikamu chesimba rekupenya remuenzaniso wakajairwa, uye zvinoenderana nehunhu hwepigment nekupararira kwayo.Paunenge uchisarudza colorant, zvinowanzodiwa kuti usarudze colorant ine simba rakasimba reting kuti uderedze huwandu hweruvara.
(2) Simba rekufukidza rakasimba.
Simba rekuhwanda (strong hiding power) zvinoreva kugona kwe pigment kuvhara ruvara rwekumashure kwechinhu kana ichinge yaiswa pamusoro pechinhu.Simba rekuhwanda rinogona kuratidzwa nenhamba uye rakaenzana nehuremu hwe pigment (g) inodiwa payuniti yepamusoro nzvimbo kana ruvara rwekumashure rwakavharwa zvachose.Kazhinji, inorganic pigment ine simba rekuvharira rakasimba, nepo organic pigment iri pachena uye isina simba rekuvharira, asi inogona kuve nekuvhara simba kana ikashandiswa pamwe chete netitanium dioxide.
(3) Kupisa kwakanaka kwekudzivirira.
Heat resistance of pigment zvinoreva kushanduka kweruvara kana zvimiro zve pigment pakupisa tembiricha.Kazhinji, nguva yekudzivirira kupisa kwepigment inodiwa kuva 4 ~ 10min.Kazhinji, inorganic pigment ine yakanaka kupisa kupisa uye haisi nyore kuora patembiricha yekugadzira epurasitiki, nepo organic pigment ine kushomeka kwekupisa.
(4) Kuramba kwakanaka kwekufamba.
Pigment migration inoreva chiitiko chekuti zvigadzirwa zvepurasitiki zvine mavara zvinowanzosangana nezvimwe zvinyoro, zvinwiwa, magasi uye zvimwe zvinhu, uye pigment inotama kubva mukati mepurasitiki ichienda kune yakasununguka pamusoro pechigadzirwa kana zvinhu zvinosangana nazvo.Kutama kwemavara mumapurasitiki kunoratidza kusawirirana pakati pemavara uye resin.Kazhinji, pigment uye organic pigment zvine fluidity yakanyanya, nepo inorganic pigment ine yakaderera fluidity.
(5) Kuramba kwakanaka kwechiedza uye kusagadzikana kwemamiriro ekunze.
Lightfastness uye weatherability zvinoreva kugadzikana kwemavara pasi pechiedza uye mamiriro echisikigo.Kutsanya kwechiedza kune hukama neiyo molecular chimiro che colorant.Akasiyana colorants ane akasiyana mamorekuru zvimiro uye lightfastness.
(6) Yakanaka acid kuramba, alkali kuramba, solvent resistance uye chemical resistance.
Zvigadzirwa zvepurasitiki zveindasitiri zvinowanzo shandiswa kuchengetedza makemikari uye kutakura makemikari akadai seasidhi uye alkalis, saka iyo asidhi uye alkali kuramba kwe pigment kunofanirwa kutariswa.
