Qhov kev xaiv ntawm ntub kev sib tsoo thiab sib tsoo qhuav rau hauv cov xim ua yog yog xws li cov xim hom, lub hom phiaj particle loj, thiab cov nqi tsim khoom. Hauv qab no yog kev txheeb xyuas ntawm ob txoj kev los pab txiav txim siab cov kev xaiv tsim nyog tshaj plaws:
1. Cov txheej txheem ntub sib tsoo
Cov ntaub ntawv tsim nyog:
El · ultrafine lossis nano {{- nplai pigments (piv txwv li {}}}}}}}}} {cov inks, thiab tshuaj pleev ib ce).
Yuav tsum muaj kev cuam tshuam cov kev ua kom muaj kev sib cais
{{{{- Cov Poskments rhiab (ntub kev sib tsoo kom tswj qhov kub thiab txias los tiv thaiv kev ua kom sov).
Qhov Zoo:
· Finer palcle loj:Cov kua nruab nrab (xws li dej lossis cov kuab tshuaj) txo cov particle agglomeration, ua tiav submicron lossis txawm tias ib qho kev sib tsoo ntawm cov dej sib tsoo (piv txwv li, d90 <1 μm).
· Kev tawg ua tau zoo:Ncaj qha cov tsim tawm cov xim slurry slurry, firilitating ua qauv txheej txheem tom ntej (piv txwv li, cov khoob khoob khoob).
· Tsawg hmoov av paug:Haum rau lom lossis siab {- purity pigments (piv txwv li, kws tshuaj {}} qib titanium dioxide).
· Cov khoom siv tau sib haum xeeb:Kab rov tav mills ua ke nrog siab - ntom zeem kev sib tsoo, thaum hnav tsis kam txo cov phom sij tsis huv.
Txwv:
· Xav kom cov kauj ruam qhuav ntxiv, nce kev siv zog thiab cov nqi.
Fresh kua nruab nrab tej zaum yuav muaj kev cuam tshuam rau cov tshuaj ruaj khov ntawm qee cov pigments (piv txwv li, hydrolysis-}} rhiab organic).
2. Qhuav sib tsoo txheej txheem
Cov ntaub ntawv tsim nyog:
· Ntxhib rau nruab nrab - Cov kev yuav tsum tau ua (piv txwv li, d50 tus txheej txheem ua yeeb yam lossis yas masterbatches).
· Numbery-}} Kev tsim tau zoo (tsis muaj kev xav tau cov kuab tshuaj lossis cov kauj ruam ziab).
· Hydrophobic pigments (piv txwv li, qee cov carbon dub lossis xim hlau pigments).
Qhov Zoo:
· Txheej txheem yooj yim:Ncaj qha tsim cov hmoov qhuav, zoo tagnrho rau cov hmoov pleev xim lossis muab cov qauv ua kom qhuav.
· Cov Khoom Noj Tsawg Zog:Tshem tawm qhov xav tau ntawm slurry ziab, ua rau nws haum rau loj - nplai ntau lawm.
· Tsis muaj qhov hnyav txwv:Zam kev siv tshuaj lom neeg ntawm cov qe tawm thiab cov pigments.
Txwv:
· Particle loj constrains:Nyuaj tau ua tiav ruaj khov ultrafine sib tsoo (nquag mus rau agglomeration, uas yuav tsum muaj ntxiv dispersion kauj ruam).
· Cov plua plav tawg kev pheej hmoo:Yuav tsum tau nruj tawg - kev ntsuas pov thawj rau cov xim liab (piv txwv li, pigic pigments).
· Cov Teeb Meem Thaum Tshav Kub Kub:High -} Ceev cov kev sib tsoo qhuav yuav ua rau muaj kev kub ntxhov, ua rau cov xim dispoloration lossis degradation.
