Ọtụtụ ndị mmadụ enweghị ike ịmata ọdịiche dị n'etiti hydroxyethyl cellulose na ethyl cellulose.Hydroxyethyl cellulose na ethyl cellulose bụ ihe abụọ dị iche iche.Ha nwere njirimara ndị a.
1 Hydroxyethyl cellulose:
Dị ka a na-abụghị ionic surfactant, na mgbakwunye na ndim, suspending, njide, flotation, film-akpụ, na-agbasasị, na-ejigide mmiri na inye nchebe colloid, ọ nwekwara ihe ndị a Njirimara:
1. HEC na-agbaze na mmiri ọkụ ma ọ bụ mmiri oyi, ọ naghị eme ka ọ dị elu na okpomọkụ dị elu ma ọ bụ na-esi ísì ụtọ, na-eme ka ọ nwee ọdịdị dị iche iche nke solubility na viscosity, na gelation na-abụghị thermal;
2. Ọ bụ ndị na-abụghị ionic na ike ibikọ ọnụ na a dịgasị iche iche nke ọzọ mmiri-soluble polymers, surfactants na salts, na bụ magburu onwe colloidal thickener nwere elu-concentration electrolyte ngwọta;
3. Ikike njide mmiri dị okpukpu abụọ dị elu karịa nke methyl cellulose, ọ na-enwekwa usoro nchịkwa ka mma.
4. N'iji ya tụnyere methyl cellulose a ma ama na hydroxypropyl methyl cellulose, ike mgbasa nke HEC bụ nke kachasị njọ, ma colloid nchebe nwere ike kachasị ike.
2 ethyl cellulose
Ọ bụ cellulose ether na-abụghị ionic nke a na-apụghị ịsacha n'ime mmiri ma soluble na organic solvents.O nwere njirimara ndị a:
1. Ọ dịghị mfe ọkụ.
2. Ezi nkwụsi ike nke okpomọkụ na ezigbo thermoplasticity.
3. Ọ dịghị discoloration ka ìhè anyanwụ.
4. Ezi mgbanwe.
5. Ezi dielectric Njirimara.
6. Ọ nwere magburu onwe alkali iguzogide na adịghị ike acid iguzogide.
7. Ezi arụmọrụ mgbochi ịka nká.
8. Ezigbo iguzogide nnu, oyi na mmiri absorption.
9. Stable na chemicals, nchekwa ogologo oge na-enweghị mmebi.
10. Dakọtara na ọtụtụ resins na ezigbo ndakọrịta na ihe niile plasticizers.
11. Ọ dị mfe ịgbanwe agba n'okpuru ebe alkaline siri ike na ọnọdụ okpomọkụ.
