Tanthauzo la kubalalitsidwa kwa pigment pa utoto wa pulasitiki

Kubalalika kwa pigment ndikofunikira kwambiri pakupaka utoto wa mapulasitiki.Zotsatira zomaliza zamtundukubalalitsidwa osati kumakhudza tinting mphamvu ya pigment, komanso kumakhudza maonekedwe a mtundu mankhwala (monga mawanga, mikwingwirima, gloss, mtundu ndi mandala), komanso mwachindunji zimakhudza mtundu wa mankhwala achikuda, monga mphamvu, elongation, kukana kwa mankhwala.Kukalamba ndi resistivity, etc., zimakhudzanso ntchito processing ndi ntchito mapulasitiki (kuphatikiza mtundumasterbatch).

The dispersibility wa inki mu mapulasitiki amatanthauza mphamvu ya inki kuchepetsa kukula kwa aggregates ndi agglomerates kwa kukula ankafuna pambuyo kunyowetsa.Pafupifupi mphamvu zonse za ma pigment mu ntchito za pulasitiki zimatengera momwe ma pigment amatha kumwazikana bwino.Choncho, dispersibility wa inki ndi chizindikiro chofunika kwambiri ntchito pautoto wa pulasitiki.

Popanga pigment, kristalo wa kristalo umayamba kupangidwa.Kukula kwa kristalo wa kristalo ndi kristalo imodzi kumayambiriro, koma posakhalitsa imakula kukhala polycrystal yokhala ndi mawonekedwe a mosaic.Zachidziwikire, tinthu tating'onoting'ono tidakali bwino, ndipo kukula kwake kwa tinthu tating'onoting'ono ndi pafupifupi 0.1 mpaka 0.5 μm, zomwe nthawi zambiri zimatchedwa tinthu tating'onoting'ono kapena tinthu tating'onoting'ono.particles pulayimale amakonda aggregate, ndi aggregated particles amatchedwa yachiwiri particles.Malinga ndi njira zosiyanasiyana zophatikizira, tinthu tating'onoting'ono timagawika m'magulu awiri: imodzi ndikuti makristalo amalumikizidwa ndi m'mphepete mwa kristalo kapena ngodya, kukopa pakati pa makhiristo ndi ochepa, tinthu tating'onoting'ono tating'onoting'ono, ndipo timasiyanitsidwa mosavuta ndi makristalo. kubalalitsidwa, komwe kumatchedwa attachment.Aggregate;Mtundu wina, makhiristo omwe ali ndi ndege, zomwe zimapangitsa chidwi pakati pa makhiristo zimakhala zolimba, tinthu tating'onoting'ono timakhala olimba, malo athunthu a ophatikizidwawo ndi ocheperako kuposa ma tinthu tating'onoting'ono. ndipo ma aggregates amadalira njira zobalalika.Zimakhala zovuta kumwazikana.
