hydroxyethyl cellulose na ethyl cellulose

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

hydroxyethyl cellulose

Dịka ihe na-adịghị eme ka mmiri dị n'ime ya, na mgbakwunye na ịka nká, nkwụsịtụ, ijikọ, flotation, ịmepụta ihe nkiri, ịgbasa, idobe mmiri na inye colloids nchebe, o nwekwara ihe ndị a:

1. A na-agbaze HEC n'ime mmiri ọkụ ma ọ bụ oyi, ọ naghịkwa agbapụta n'oge okpomọkụ dị elu ma ọ bụ mgbe ọ na-esi, nke mere na o nwere ọtụtụ njirimara ịgbaze na viscosity, yana njikọta na-abụghị okpomọkụ;

2. Ihe na-abụghị ionic n'onwe ya nwere ike ibikọ ọnụ na ọtụtụ polymers ndị ọzọ na-agbaze mmiri, surfactants na nnu, ọ bụkwa ezigbo ihe na-eme ka colloidal thickener nwee ihe ngwọta electrolyte dị elu;

3. Ike nchekwa mmiri dị okpukpu abụọ karịa nke methyl cellulose, ọ na-achịkwakwa mmiri nke ọma;

4. Ma e jiri ya tụnyere methyl cellulose na hydroxypropyl methyl cellulose a ma ama, ikike ịgbasa nke HEC bụ nke kacha njọ, mana colloid nchebe nwere ikike kachasị ike.

Ethyl cellulose

Ọ bụ ihe na-abụghị ionic cellulose ether nke a naghị agbaze na mmiri mana ọ na-agbaze na ihe ndị sitere n'okike. O nwere njirimara ndị a:

1. Ọ dịghị mfe ịgba ọkụ.

2. Ezigbo nkwụsi ike okpomọkụ na ezigbo thermoplasticity.

3. Enweghị agba ìhè anyanwụ.

4. Ezigbo mgbanwe.

5. Ezigbo ihe onwunwe dielectric.

6. O nwere ezigbo iguzogide alkali na ike iguzogide acid adịghị ike.

7. Ọ na-arụ ọrụ nke ọma megide ịka nká.

8. Ọ na-eguzogide nnu, oyi na mmiri nke ọma.

9. Na-adịgide adịgide nye kemịkalụ, na-echekwa ya ruo ogologo oge n'enweghị mmebi.

10. Dakọtara na ọtụtụ resins ma nwee ezigbo ndakọrịta na ihe nrụpụta plastik niile.

11. Ọ dị mfe ịgbanwe agba n'okpuru gburugburu alkaline siri ike na ọnọdụ okpomọkụ.
