Dispersing wothandizira NNOamagwiritsidwa ntchito m'munda wa mankhwala kubalalitsidwa, ndiye utoto, inki ndi zina pigment phala akupera. Kuphatikiza apo, kuwonjezera dispersant mu utomoni kapena emulsion kumatha kusintha magwiridwe antchito a thupi lalikulu. Ntchito yayikulu ndikutsitsa thonje, kupewa kumira komanso kuthandizira kubalalitsidwa. Makhalidwe atatu ndi mawonekedwe ofunikira a dispersants ndipo amagwiritsidwa ntchito pozindikiraDispersing wothandizira NNO!

Choyamba, kuchepetsa mamasukidwe akayendedwe ndi kuonjezera pigment katundu. Kugwiritsa ntchito moyeneraDispersing wothandizira NNO, kukhuthala kwa phala kukanachepetsedwa kwambiri. Chifukwa ndi kuonjezera pigment katundu, kusintha zokolola kuchita bwino.

Chachiwiri, anthu ambiri omwe amachepetsa magazi kuundana ndikuwongolera zomangamanga ndikuchita bwino azichita mayeso ofufuza powunika zokhuthala. Zolakwika dispersant collocation, chala kukhudza ndi osati anakhudza mbali zidzaonekera zoonekeratu kusiyana mtundu, mtundu luso condensed pigment adzakhala kuchepetsedwa, kubweretsa tona ndi utoto zovuta kumanga. Kukhazikika kwa maiwe amitundu kumatha kuwonedwanso ndi kuyesa kwa mbale zoyenda.

Chachitatu, onjezerani kuwonekera kapena kufalitsa. Kwa utoto, phala likamaonekera kwambiri, limakhala bwino. Kwa utoto wamba, udzu wobiriwira umakhala wokwera kwambiri. Ndipotu, zimagwirizana ndi kukula kwa pigment. Zina zikuwonetsa kuti kuwonjezera pa refractive index, kugawa tinthu tating'onoting'ono ndi chinthu china chofunikira powonekera. Pamene kukula kwa tinthu kumawonjezeka, mphamvu yomwaza kuwala imayamba kuchepa pamene ikuwonjezeka. Kukhoza kumwaza kuwala kumapangitsanso mphamvu yokutira ya pigment, pamene mphamvu yobalalika imakhala yamphamvu, ndipo ngati kukula kwa tinthu kukupitirirabe, mphamvu yophimba idzachepa. Komabe, ngati kukula kwa tinthu ta pigment kuli kochepa kuposa mtengo wina, kuwonekera kudzawonjezeka pamene kukula kwa tinthu kumachepa. Dispersant sangasinthe makhalidwe a pigment palokha, koma akhoza kulamulira tinthu kukula kufalitsa pigment, kuti tikwaniritse bwino kwambiri mtundu kwenikweni.

Kodi kunyowetsa dispersant, kunyowetsa dispersant ndi mtundu wa surfactant wokhala ndi hydrophilic ndi lipophilic. Makamaka insoluble mu zamadzimadzi, chida akhoza wogawana kumwazikana olimba particles mu organic inki, kuteteza olimba particles kukhazikika ndi aggregating kupanga nthumwi zofunika kukhazikika kuyimitsidwa.

Ndiye kodi chonyowetsa chanu chabwino chingawoneke bwanji?

Ngati ndi chinthu chomwe chimatha kuviika zinthu zolimba m'madzi. Chepetsani kukangana kwapamtunda kapena kukangana kwapakati kuti madzi afalikire kapena kulowa pamwamba pa chinthu cholimba, potero kunyowetsa cholimbacho. Ndipo kawirikawiri pamwamba yogwira wothandizira, monga sopo, sulfonated mafuta, ufa ndi zina zotero. Mutha kugwiritsanso ntchito soya lecithin, acetylene, mercaptan, mercaptan acetal, etc.

Onsewo ndi otaya madzi

1. Adsorb pamwamba pa olimba particles kuti condensed pamwamba olimba particles yonyowa.

2. Pamwamba pa particles olimba amapanga adsorption wosanjikiza kuonjezera mlandu padziko olimba particles ndi kusintha anachita mphamvu pakati particles kupanga zopinga atatu azithunzi.

3. Pangani pamwamba pa tinthu tating'onoting'ono kuti tipangitse dongosolo la bilayer, kunja kwa madzi otayika kumakhala ndi mgwirizano wamphamvu, kuonjezera mlingo wa tinthu tating'ono tomwe timanyowa ndi madzi. Ma particles olimba amasiyanitsidwa ndi electrostatic repulsion.

4. Uniform dongosolo, kusintha kuyimitsidwa ntchito, palibe mpweya, thupi ndi mankhwala katundu wa dongosolo lonse ndi chimodzimodzi.
