Ua kapa ʻia ʻo Dispersant i ka wetting and dispersing agent.Ma kekahi ʻaoʻao, loaʻa ka hopena wai, ma ka ʻaoʻao ʻē aʻe, hiki ke hoʻopili ʻia kekahi ʻaoʻao o kāna pūʻulu ikaika ma ka ʻili o ka puaʻa i ʻoki ʻia i loko o nā ʻāpana maikaʻi, a ʻo ka hopena ʻē aʻe e hoʻoheheʻe ʻia i loko o ka waihona kumu e hana i ka papa adsorption (ka ʻoi aku ka nui o nā pūʻulu adsorption, ʻoi aku ka lōʻihi o ke kaulahao, ʻoi aku ka mānoanoa o ka papa adsorption) e hana i ka repulsion charge (wai-based paint) a i ʻole entropy repulsion (solvent-based paint), i hiki ke hoʻopuehu ʻia nā ʻāpana puaʻa a hoʻokuʻu ʻia i ka pena no lōʻihi e pale hou i ka flocculation.Mālama kēia i ka paʻa o ka mālama ʻana i ka ʻōnaehana pena.
 
Hoʻohana mau ʻia nā ʻano dispersants.
1.Anionic pulu ana a me ka dispersing agent
Hoʻokumu ʻia ka hapa nui o lākou me ke kaulahao hydrocarbon non-polar a me ka hui hydrophilic polar.Aia nā pūʻulu ʻelua ma nā ʻaoʻao ʻelua o ka mole, e hana ana i kahi asymmetric hydrophilic a me oleophilic molecular structure.ʻO kāna mau ʻano ʻano: sodium oleate C17H33COONa, carboxylate, sulfate (RO-SO3Na), sulfonate (R-SO3Na), a me nā mea ʻē aʻe. a hoʻohana nui ʻia e like me nā dispersants ʻano flocculation.

2.Cationic wetting a me ka dispersing agent
ʻAʻole lākou i polar base positively charged compounds, ka hapa nui o nā amine salts, quaternary amine salts, pyridinium salts, etc. Cationic surfactants i ka mana adsorption ikaika a ʻoi aku ka maikaʻi o ka hoʻopuehu ʻana i ke kalapona ʻeleʻele, nā mea hao like ʻole a me nā puaʻa kūlohelohe, akā pono e hoʻomaopopo ʻia. e hana kemika me ka pūʻulu carboxyl i loko o ka mea kumu, a e hoʻomaopopo hoʻi ʻaʻole pono e hoʻohana like ʻia me nā dispersant anionic.

3.Controlled noa radical type hyperdispersant
ʻO ka lua, ke kuleana o ka dispersant
1. Hoʻonui i ka nani a hoʻonui i ka hopena pae.
2.Prevent lana kala a me ka pua.
3.Improve kala kala.
4. Hoʻemi i ka viscosity a hoʻonui i ka hoʻouka puaʻa.
5.Reduce flocculation, hoʻonui i ka hana a me ka hoʻohana.
6.Prevent recoarse a hoʻonui i ka mālama paʻa.
7.E hoʻonui i ka hoʻolaha kala a me ka saturation kala.
8.E hoʻonui i kaʻike a iʻole ka mana uhi.
9.E hoʻomaikaʻi i ka hana wili a hoʻemi i ka uku hana.
10. Kāohi i ka hoʻoponopono ʻana.
