Nhazi nke Ngwaahịa Methyl Cellulose

Enwere ike ịkewa ngwaahịa methyl cellulose (MC) dabere na ihe dị iche iche dị ka ọkwa viscosity ha, ogo nnọchi (DS), ịdị arọ molecular, na ngwa. Nke a bụ ụfọdụ nhazi ọkwa nke ngwaahịa methyl cellulose:

1. Ọkwa viscosity:
   • A na-ekewakarị ngwaahịa methyl cellulose dabere na akara viscosity ha, nke kwekọrọ na viscosity ha na ngwọta mmiri. A na-atụkarị viscosity nke ngwọta methyl cellulose na centipoise (cP) na ntinye uche na ọnọdụ okpomọkụ. Akara viscosity nkịtị gụnyere obere viscosity (LV), viscosity ọkara (MV), viscosity dị elu (HV), na ultra-high viscosity (UHV).
2. Ogo nke nnọchi (DS):
   • A pụkwara ịkewa ngwaahịa methyl cellulose dabere na ogo ngbanwe ha, nke na-ezo aka na nkezi ọnụọgụ hydroxyl otu glucose nke ejirila methyl dochie ya. Ụkpụrụ DS dị elu na-egosi ogo ngbanwe dị ukwuu ma na-ebutekarị solubility dị elu yana okpomọkụ gelation dị ala.
3. Arọ Molecular:
   • Ngwaahịa methyl cellulose nwere ike ịdịgasị iche na ịdị arọ molekụla, nke nwere ike imetụta ihe onwunwe ha dị ka solubility, viscosity, na gelation omume. Ngwaahịa methyl cellulose dị arọ nke dị elu na-enwekarị viscosity dị elu yana njirimara gelling siri ike ma e jiri ya tụnyere ngwaahịa arọ molekụla dị ala.
4. Ngwa-Ọkachamara akọwapụtara:
   • Enwere ike kewaa ngwaahịa methyl cellulose dabere na ngwa ha chọrọ. Dịka ọmụmaatụ, enwere akara ule methyl cellulose nke kachasị maka nhazi ọgwụ, ngwaahịa nri, ihe owuwu ụlọ, ihe nlekọta onwe onye, ​​na ngwa ụlọ ọrụ ndị ọzọ. Akara ule ndị a nwere ike haziela akụrụngwa iji mezuo ihe achọrọ nke ngwa ha.
5. Ọpụrụiche Ọpụrụiche:
   • Emebere ụfọdụ ngwaahịa methyl cellulose maka ngwa pụrụ iche ma ọ bụ nwee akụrụngwa pụrụ iche ahaziri maka ojiji akọwapụtara. Ọmụmaatụ gụnyere usoro methyl cellulose nwere nkwụsi ike ọkụ, mma njide mmiri, njirimara ntọhapụ a na-achịkwa, ma ọ bụ ndakọrịta na ụfọdụ mgbakwunye ma ọ bụ ihe mgbaze.
6. Aha ahia na ụdị:
   • Enwere ike ịre ngwaahịa methyl cellulose n'okpuru aha azụmaahịa ma ọ bụ ụdị dị iche iche site n'aka ndị nrụpụta dị iche iche. Ngwaahịa ndị a nwere ike ịnwe ihe ndị yiri ya mana ọ nwere ike ịdịgasị iche na nkọwapụta, ịdịmma na arụmọrụ. Aha azụmaahịa a na-ahụkarị maka methyl cellulose gụnyere Methocel®, Cellulose Methyl, na Walocel®.

Enwere ike ikewa ngwaahịa methyl cellulose dabere na ihe ndị dị ka ọkwa viscosity, ogo nnọchi anya, ịdị arọ molecular, akara ngwa-kpọmkwem, akara ule pụrụ iche, na aha ahia. Ịghọta nhazi ọkwa ndị a nwere ike inyere ndị ọrụ aka ịhọrọ ngwaahịa methyl cellulose kwesịrị ekwesị maka mkpa na ngwa ha kpọmkwem.
