Njirimara na ngwa nke Hydroxyethyl Methyl Cellulose HEMC

Isi njirimara nkehydroxyethyl methyl cellulose (HEMC)bụ:

1. Solubility: soluble na mmiri na ụfọdụ ihe mgbaze organic, HEMC nwere ike igbari na mmiri oyi, a na-ekpebi ihe kachasị elu naanị site na viscosity, solubility dị iche iche na viscosity, na-ebelata viscosity, otú ahụ ka solubility dị ukwuu.

2. Nguzogide nnu: ngwaahịa HEMC bụ ndị na-abụghị ionic cellulose ethers na ọ bụghị polyelectrolytes, ya mere na ọnụnọ nke metal salts ma ọ bụ organic electrolytes, ha na-adịtụ kwụsiri ike na mmiri ngwọta, ma oké mgbakwunye nke electrolytes nwere ike ime ka gelation na ọdịda.

3. Ọrụ elu: N'ihi na ngwọta mmiri nwere ọrụ ọrụ elu, enwere ike iji ya dị ka onye na-echebe colloid, emulsifier na dispersant.

4. Thermal gel: MgbeHEMCngwaahịa aqueous ngwọta na-ekpo ọkụ na a ụfọdụ okpomọkụ, ọ na-aghọ opaque, gels, na-etolite a precipitate, ma mgbe ọ na-anọgide na-mma, ọ na-alaghachi na mbụ ngwọta ala, na nke a jel na ọdịda. Okpomọkụ na-adabere na mmanụ aṅụ ha, ihe enyemaka nkwụsịtụ, colloid nchebe, emulsifiers, wdg.

5. Metabolic inertness na obere isi na isi ísì: A na-eji HEMC eme ihe n'ọtụtụ nri na ọgwụ n'ihi na ọ naghị edozi ya ma nwee obere isi na isi ísì.

6. Antifungal: HEMC nwere ikike antifungal dị mma na nkwụsi ike viscosity dị mma n'oge nchekwa ogologo oge.

7. Nkwụsi ike PH: Acid ma ọ bụ alkali adịghị emetụta viscosity nke ngwaahịa HEMC ngwaahịa aqueous, na pH uru na-akwụsi ike na nso nke 3.0-11.0.

Ngwa nkeHydroxyethyl methyl cellulose (HEMC):

Enwere ike iji hydroxyethyl methyl cellulose dị ka onye na-echebe colloid, emulsifier na dispersant n'ihi ọrụ ya na-arụ ọrụ na ngwọta mmiri. Ihe atụ nke ngwa ya bụ nke a: Mmetụta nke hydroxyethyl methyl cellulose na njirimara nke ciment. Hydroxyethyl methyl cellulose bụ ihe na-esi ísì ụtọ, nke na-enweghị ụtọ, ntụ ntụ na-adịghị egbu egbu nke na-agbaze n'ime mmiri oyi iji mepụta ngwọta doro anya na nke viscous. Ọ nwere Njirimara nke ndim, njide, na-achụsasị, emulsifying, film-akpụ, suspending, adsorbing, gelling, elu-arụ ọrụ, na-ejigide mmiri na-echebe colloid. N'ihi ọrụ na-arụ ọrụ elu nke ngwọta mmiri, enwere ike iji ya dị ka onye na-echebe colloid, emulsifier na onye na-ekesa. Hydroxyethyl methyl cellulose ngwọta aqueous nwere ezigbo hydrophilicity na ọ bụ ihe na-arụ ọrụ nke ọma na-ejigide mmiri.
