Dispersants nawonso ndi surfactants.Pali mitundu ya anionic, cationic, nonionic, amphoteric ndi polymeric.Mtundu wa anionic umagwiritsidwa ntchito kwambiri.Ma dispersing agents ndi oyenera ufa kapena makeke omwe amatha kusungunuka mosavuta ndipo amatha kuwonjezeredwa kuti azitha kumasula bwino ndikupewa kuyika popanda kusokoneza ntchito ya thupi.Iwo akhoza ankagwiritsa ntchito mitundu yonse ya chakudya ndi mankhwala ufa dispersant, chakudya, ammonium kolorayidi ndi zina feteleza dispersant, ❖ kuyanika dispersant, ceramic dispersant, sanali phosphorous detergent, kaolin dispersant, zina simenti, dispersant pepala, kufalitsidwa madzi dispersant ndi sikelo inhibitor. , etc. Zogulitsa zimakhala ndi anti-deposition effect.
Udindo wa dispersant ndi ntchito wetting dispersant kuchepetsa nthawi ndi mphamvu zofunika kuti amalize kubalalika ndondomeko, bata obalalika pigment kubalalitsidwa, kusintha pamwamba zimatha pigment particles, ndi kusintha motility wa pigment particles.Kugwiritsiridwa ntchito kwapadera kwa dispersants kumawonekera m'mbali zotsatirazi.
1. Pamitundu yonse ya chakudya ndi ufa wamankhwala, dispersant imakhala ndi anti-crystallization effect, yomwe imatha kusunga ubwino wa chakudya ndi mankhwala kuti isasinthe kwa nthawi yayitali, ndipo ndi yabwino kwambiri komanso yotetezeka yotsutsa-crystallization.
2. Ndi anti-caking agent ya feteleza wamankhwala (makamaka ammonium chloride, ammonium carbon), yomwe imatha kusunga kutayirira kwa zinthu zomwe zimayamwa chinyezi komanso kuyika zinthu ndikutalikitsa mtundu wa mankhwalawa ndikugwiritsa ntchito kuzungulira.
3. Monga dissperant wa pigment, akhoza kuzindikira kugwirizana pakati pa mankhwalawa ndi pigment particles kuzindikira kubalalitsidwa kwa pigment ndikuonetsetsa kufanana kwa utoto.
4. Monga chothandizira chothandizira mu zotsukira zopangira, mankhwalawa ali ndi ntchito yomwaza tinthu tating'onoting'ono ndi dothi la calcium sopo, chelating multivalent particles, ndipo ali ndi mphamvu zowonetsera zowonongeka ku tinthu tating'onoting'ono.Pofuna kukonza decontamination ya particle detergent, ndi yaikulu kuwirikiza ka 5 kuposa sodium tripolyphosphate yomwe imagwiritsidwa ntchito nthawi zambiri, ndipo mphamvu yobalalitsa ya sopo wa calcium ndi yaikulu ka 6 kuposa sodium tripolyphosphate.Ali ndi anti-deposition effect, anti-acid kwambiri kuposa sodium tripolyphosphate.
5. sikelo inhibitor ndi dispersant kwa kuzirala kufalitsidwa madzi akhoza mogwira kusiya kashiamu carbonate, calcium carbonate lonse, dispersant akhoza chelate calcium ayoni, kotero kuti machulukitsidwe ndende ya ayoni kashiamu chinawonjezeka ndi kangapo, pamene ndende ya ayoni kashiamu ndi okwera kwambiri, pali Komanso kukhala sikelo mpweya, pamwamba pa sikelo particles, kuteteza sikelo kusonkhanitsa kupanga particles lalikulu ndi mpweya, ngakhale mapangidwe lonse wosanjikiza ndi lotayirira kwambiri, zosavuta kutsukidwa ndi madzi, kuti kukwaniritsa cholinga cha kupewa sikelo, kuthetsa masikelo.
