Hydroxyethyl cellulose (HEC) Njirimara na ojiji

Dị ka onye na-abụghị ionic surfactant,hydroxyethyl cellulose(HEC) nwere ihe ndị a na mgbakwunye na ịgbatị, nkwụsịtụ, njide, flotation, imepụta ihe nkiri, ịgbasa, idowe mmiri na inye colloid nchebe:

1. HEC na-agbaze na mmiri ọkụ ma ọ bụ mmiri oyi, ọ naghị emepụta ya na okpomọkụ dị elu ma ọ bụ na-esi ísì ụtọ, ya mere ọ nwere ọtụtụ ihe solubility na njirimara viscosity, na gelation na-abụghị thermal;

2. Onye na-abụghị ionic n'onwe ya nwere ike ibikọ ọnụ na polymers ndị ọzọ na-edozi mmiri, surfactants na salts n'ọtụtụ dị iche iche, ma bụrụ ezigbo colloidal thickener nwere ihe ngwọta electrolyte dị elu;

3. Ikike njide mmiri dị okpukpu abụọ dị elu karịa nke methyl cellulose, ọ na-enwekwa usoro nchịkwa ka mma.

4. E jiri ya tụnyere methyl cellulose a ma ama na hydroxypropyl methyl cellulose, ike ịgbasa nke HEC bụ nke kachasị njọ, ma ikike colloid nchebe bụ ike kachasị ike.

Otu esi eji hydroxyethyl cellulose? 

1. Soro ozugbo na mmepụta

1. Tinye mmiri dị ọcha na nnukwu ịwụ nke nwere nnukwu blender.

2. Malite na-akpali akpali na-aga n'ihu na obere ọsọ ma jiri nwayọọ nwayọọ gbanye hydroxyethyl cellulose n'ime ngwọta nke ọma.

3. Gaa n'ihu na-akpali akpali ruo mgbe etinyere ihe niile.

4. Mgbe ahụ tinye ihe nchebe ọkụ, ihe mgbakwunye alkaline dị ka pigmenti, ihe enyemaka na-agbasa, mmiri amonia.

5. Nwuo ruo mgbe niile hydroxyethyl cellulose na-agbaze kpamkpam (viscosity nke ngwọta na-abawanye nke ọma) tupu ịgbakwunye ihe ndị ọzọ na usoro ahụ, na-egweri ruo mgbe ọ ga-aghọ.
