Hydroxyethyl cellulose na ethyl cellulose

Hydroxyethyl cellulose na ethyl cellulose bụ ihe abụọ dị iche iche. Ha nwere njirimara ndị a.

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, nke mere na ọ nwere ọdịdị dị iche iche nke solubility na viscosity, na gelation na-abụghị thermal;

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

3. Ikike njide mmiri dị okpukpu abụọ 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.

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.
