Zosakaniza ndi zowonjezera pamwamba zomwe zimagwiritsidwa ntchito kukhazikika tinthu tolimba m'zinthu monga zomatira, utoto, mapulasitiki ndi zosakaniza za pulasitiki.

Kale, zophimba kwenikweni sizinkafunika zotulutsira madzi. Machitidwe monga utoto wa alkyd ndi nitro sankafunika zotulutsira madzi. Zotulutsira madzi sizinawonekere mpaka utoto wa acrylic resin ndi utoto wa polyester resin. Izi zikugwirizananso kwambiri ndi chitukuko cha utoto, chifukwa kugwiritsa ntchito utoto wapamwamba sikungalekanitsidwe ndi thandizo la zotulutsira madzi.
Zosakaniza ndi zowonjezera pamwamba zomwe zimagwiritsidwa ntchito kukhazikika tinthu tolimba m'zinthu monga zomatira, utoto, mapulasitiki ndi zosakaniza za pulasitiki. Mbali imodzi yake ndi unyolo wosungunula womwe ungasungunuke m'zinthu zosiyanasiyana zosanganikirana, ndipo mbali inayo ndi gulu lolumikiza utoto lomwe limatha kumizidwa pamwamba pa mitundu yosiyanasiyana ya utoto ndikugwiritsidwa ntchito kusintha kukhala mawonekedwe olimba/amadzimadzi (njira ya pigment/resin).

Njira yothetsera utomoni iyenera kulowa m'malo omwe ali pakati pa ma agglomerate a pigment. Ma pigment onse amapezeka ngati ma agglomerate a pigment, omwe ndi "zosonkhanitsa" za tinthu ta pigment, ndi mpweya ndi chinyezi zomwe zili m'malo amkati pakati pa tinthu ta pigment. Tinthu ta pigment timalumikizana m'mphepete ndi m'makona, ndipo kuyanjana pakati pa tinthu ta pigment ndi kochepa, kotero mphamvu izi zitha kugonjetsedwa ndi zida wamba zofalitsira. Kumbali ina, ma agglomerate ndi ochepa kwambiri, ndipo pali kukhudzana maso ndi maso pakati pa tinthu ta pigment, kotero zimakhala zovuta kwambiri kuwagawa m'tinthu ta pigment. Panthawi yopera ma pigment, ma agglomerate a pigment amachepa pang'onopang'ono; mkhalidwe wabwino ndikupeza tinthu ta primary.

Njira yopukusira utoto ingagawidwe m'magawo atatu otsatirawa: gawo loyamba ndi kunyowetsa. Pansi pa kusakaniza, mpweya wonse ndi chinyezi pamwamba pa utoto zimatuluka ndikusinthidwa ndi yankho la resin. Chotulutsira utoto chimathandizira kuti utoto ukhale wonyowa, kusandutsa mawonekedwe olimba/gasi kukhala mawonekedwe olimba/amadzimadzi ndikuwonjezera magwiridwe antchito opukusira; gawo lachiwiri ndi njira yeniyeni yopukusira utoto. Kudzera mu mphamvu yamakina ndi mphamvu yodula, ma agglomerate a utoto amasweka ndipo kukula kwa tinthu kumachepetsedwa kukhala tinthu toyambira. Utoto ukatsegulidwa ndi mphamvu yamakina, chotulutsira utoto chimayamwa ndikukulunga tinthu tating'onoting'ono tating'ono; mu gawo lomaliza lachitatu, kufalikira kwa utoto kuyenera kukhala kokhazikika mokwanira kuti kupewe kupanga kugwedezeka kosalamulirika.

Kugwiritsa ntchito chotulutsira madzi choyenera kungathandize kuti tinthu ta utoto tisakhale patali bwino popanda kubweretsa kukhudzana. Nthawi zambiri, pamafunika kuti tinthu ta utoto tisakhale ndi mpweya wabwino. Nthawi zina, kufalikira kwa utoto kumatha kukhala kokhazikika pansi pa mikhalidwe yolamulidwa ya coflocculation. Zothandizira kunyowetsa zimatha kuchepetsa kusiyana kwa mphamvu ya pamwamba pakati pa utoto ndi yankho la resin, zomwe zimapangitsa kuti ma agglomerate a pigment anyowe ndi resin; zothandizira kufalitsa madzi zimawonjezera kukhazikika kwa kufalikira kwa utoto. Chifukwa chake, chinthu chomwecho nthawi zambiri chimakhala ndi ntchito zothandizira kunyowetsa ndi kufalitsa.

Kufalikira kwa utoto ndi njira yochokera ku mtundu wa chinthu chimodzi kupita ku mtundu wina. Pamene kukula kwa tinthu tating'onoting'ono kumachepa ndipo malo a pamwamba akuwonjezeka, mphamvu ya pamwamba pa dongosolo imawonjezekanso.
Popeza mphamvu ya pamwamba pa dongosololi imachepetsa mwadzidzidzi, kuwonjezeka kwa malo pamwamba kumawonekera bwino, mphamvu zambiri zimafunika kugwiritsidwa ntchito kuchokera kunja panthawi yopukutira, ndipo mphamvu yokhazikika ya dispersant imafunika kuti dongosololi likhale lolimba. Kawirikawiri, utoto wa inorganic uli ndi tinthu tating'onoting'ono tating'onoting'ono, malo otsika a pamwamba, komanso polarity yapamwamba, kotero zimakhala zosavuta kufalikira ndi kukhazikika; pomwe utoto wosiyanasiyana wa organic ndi carbon black uli ndi tinthu tating'onoting'ono tating'onoting'ono, malo akuluakulu a pamwamba, ndi polarity yochepa ya pamwamba, kotero zimakhala zovuta kuzifalitsa ndi kuzikhazikitsa.

Chifukwa chake, zinthu zotulutsira utoto zimapereka mbali zitatu zazikulu za magwiridwe antchito: (1) kukonza kunyowa kwa utoto ndikuwongolera magwiridwe antchito opukutira; (2) kuchepetsa kukhuthala ndikuwongolera kugwirizana ndi zinthu zoyambira, kukonza kunyezimira, kudzaza ndi kuonekera bwino kwa chithunzi, komanso kukonza kukhazikika kwa malo osungira; (3) kuwonjezera mphamvu ya utoto ndi kuchuluka kwa utoto ndikukweza kukhazikika kwa utoto.

Nanjing Reborn New Materials imaperekachonyowetsa utoto ndi zokutira, kuphatikizapo zina zomwe zimagwirizana ndi Disperbyk.

In nkhani yotsatira, tifufuza mitundu ya zofalitsa m'nyengo zosiyanasiyana ndi mbiri ya chitukuko cha zofalitsa.
