ozi

A na-akpọkwa onye mgbasa ozi wetting na dispersing agent.N'otu aka ahụ, ọ nwere wetting mmetụta, n'aka nke ọzọ, otu njedebe nke ya nọ n'ọrụ otu nwere ike adsorbed n'elu pigmenti anuahade n'ime ezi ahụ, na njedebe nke ọzọ na-agbaze n'ime isi ihe na-etolite adsorption oyi akwa (na njedebe). ọzọ adsorption dị iche iche, ogologo nke yinye njikọ, na thicker na adsorption oyi akwa) na-emepụta chaja repulsion (mmiri dabeere agba) ma ọ bụ entropy repulsion (ihe mgbaze dabeere agba), nke mere na pigmenti ahụ nwere ike gbasasịa na kwụsịtụrụ na agba maka. ogologo oge iji zere flocculation ọzọ.Nke a na-eme ka nkwụsi ike nchekwa nke usoro agba.
 
Ụdị mgbasa ozi a na-ejikarị eme ihe.
1.Anionic wetting na dispersing gị n'ụlọnga
Ọtụtụ n'ime ha bụ ndị na-abụghị polar, hydrocarbon yinye na-adịghị mma ebubo na polar hydrophilic otu.Otu abụọ ahụ dị na nsọtụ abụọ nke molekul ahụ, na-eme ka asymmetric hydrophilic na oleophilic molecular Ọdịdị.Ụdị ya dị iche iche bụ: sodium oleate C17H33COONa, carboxylate, sulfate (RO-SO3Na), sulfonate (R-SO3Na), wdg. Ndakọrịta nke anionic dispersants dị mma, na polycarboxylic acid polymers, wdg nwekwara ike tinye ya na ihe mkpuchi dabeere na ihe mgbaze. na-eji ọtụtụ ebe dị ka flocculation-ụdị dispersants na-achịkwa.

2.Cationic wetting na dispersing gị n'ụlọnga
Ha bụ ndị na-abụghị pola isi kwesịrị ebubo ogige, tumadi amine salts, quaternary amine salts, pyridinium salts, wdg Cationic surfactants nwere ike adsorption ike na nwere mma dispersion mmetụta na carbon ojii, dị iche iche ígwè oxides na organic pigments, ma ọ ga-kwuru. na ha na-emeghachi omume kemịkalụ na otu carboxyl n'ime ihe ndị dị na isi, ma rịba ama na e kwesịghị iji ha mee ihe n'otu oge na ndị na-ekesa anionic.

3.Controlled free radical ụdị hyperdispersant
Nke abụọ, ọrụ nke dispersant
1.Mmelite gloss na-abawanye mmetụta larịị.
2.Gchie sere n'elu agba na okooko.
3.Mmelite ike agba.
4.Reduce viscosity na-abawanye pigmenti loading.
5.Reduce flocculation, dịkwuo constructability na usability.
6.Mechie nlọghachi azụ na ịbawanye nkwụsi ike nchekwa.
7.Increase agba agbasa na agba saturation.
8.Increase transparency ma ọ bụ ikpuchi ike.
9.Mprove egweri arụmọrụ ma belata mmepụta ego.
