A na-akpọkwa Dispersant ihe na-eme ka mmiri dị ọcha ma gbasaa. N'otu aka, ọ nwere mmetụta mmiri dị nro, n'aka nke ọzọ, otu akụkụ nke otu ya na-arụ ọrụ nwere ike ịbanye n'elu agba ahụ a gwepịara ka ọ bụrụ obere obere ihe, a na-agbazekwa akụkụ nke ọzọ n'ime ihe ntọala iji mepụta oyi akwa mmiri (ka otu ndị na-eme ka mmiri dị ukwuu, otú ahụ ka njikọ yinye ahụ si dị ogologo, otú ahụ ka oyi akwa mmiri si dị arọ) iji mepụta chajị repulsion (agba dabere na mmiri) ma ọ bụ entropy repulsion (agba dabere na ihe mgbaze), ka e wee nwee ike ịgbasasịa ma kwụnye ihe ndị na-eme ka agba dị nro n'ime agba ahụ ruo ogologo oge iji zere flocculation ọzọ. Nke a na-eme ka nchekwa nke sistemụ agba ahụ sie ike.
 
Ụdị dispersants a na-ejikarị eme ihe.
1. Anionic wetting and dispersing gentle
Ọtụtụ n'ime ha mejupụtara otu hydrocarbon nke na-abụghị polar, nke na-anaghị agbaze nke ọma na otu hydrophilic polar. Otu abụọ ahụ dị na nsọtụ abụọ nke molekul ahụ, na-emepụta nhazi molekul asymmetric hydrophilic na oleophilic. Ụdị ya bụ: sodium oleate C17H33COONa, carboxylate, sulfate (RO-SO3Na), sulfonate (R-SO3Na), wdg. Ndakọrịta nke dispersants anionic dị mma, a pụkwara itinye polycarboxylic acid polymers, wdg. na mkpuchi dabere na ihe mgbaze ma jiri ya mee ihe nke ukwuu dị ka dispersants ụdị flocculation a na-achịkwa.

2. N'ihe gbasara mmiri ozuzo na mgbasa nke Cationic,
Ha bụ ihe ndị na-abụghị polar base positive chargeed compounds, ọkachasị nnu amine, nnu quaternary amine, nnu pyridinium, wdg. Cationic surfactants nwere ike adsorption siri ike ma nwee mmetụta mgbasa nke ọma na carbon black, iron oxides dị iche iche na agba organic, mana ekwesịrị ịmara na ha na-emeghachi omume na kemịkalụ na otu carboxyl dị na ihe ndabere, ma marakwa na ekwesighi iji ha n'otu oge na anionic dispersants.

3. Ụdị hyperdispersant nke a na-achịkwa nke ọma
Nke abụọ, ọrụ nke onye na-ekesa ihe
1. Meziwanye ihe na-egbuke egbuke ma mee ka mmetụta nhazi ahụ dịkwuo elu.
2. Gbochie agba na okooko osisi.
3.Mee ka ike agba dị mma.
4. Belata viscosity ma mee ka agba dịkwuo elu.
5. Belata flocculation, mee ka ike ịrụ ọrụ dịkwuo elu ma nwee ike iji ya mee ihe.
6. Gbochie nlọghachi azụ ma mee ka nchekwa dịkwuo mma.
7. Mee ka agba gbasaa ma jupụta agba.
8. Mee ka ike ikpuchi ihe doo anya ma ọ bụ ihe mkpuchi dịkwuo elu.
9.Mee ka arụmọrụ ịkpụcha ihe dịkwuo mma ma belata ọnụ ahịa mmepụta.
10. Gbochie nsogbu.
