Hydroxyethyl methylcellulose ni iki?

alias: hydroxyethyl methyl selulose; hydroxyethyl methyl selulose; hydroxymethyl ethyl selile; 2-hydroxyethyl methyl ether selile
Icyongereza cyitiriwe: Methylhydroxyethylcellulose; Cellulose; 2-hydroxyethyl methyl ether; HEMC; Tyopur MH [1]
Chimie: Hydroymethylmethylcellulose;Hydroxyethylmethylcellulose; Hydroxymethylethylcellulose.
Kwiyandikisha CAS: 9032-42-2

Molecule: C2H6O2 xCH4O x PhEur 2002 isobanura hydroxyethyl methylcellulose nkigice O-methylated, igice O-hydroxymethylated selile. Ibisobanuro bitandukanye bigaragazwa nigiciro kigaragara cya 2% w / v igisubizo cyamazi kuri 20 ° C, kandi igice ni mPa s.
Uburemere bwa molekuline: PhEur 2002 isobanura hydroxyethyl methylcellulose nkigice O-methylated, igice O-hydroxymethylated selile. Ibisobanuro bitandukanye bigaragazwa nigiciro kigaragara cya 2% w / v igisubizo cyamazi kuri 20 ° C, kandi igice ni mPa s.

Ibintu nyamukuru biranga hydroxyethyl methylcellulose (HEMC) ni:

1. Gukemura: Gushonga mumazi hamwe na solge organic. HEMC irashobora gushonga mumazi akonje. Kwibanda kwayo kwinshi kugenwa gusa nubwiza. Gukemura biratandukanye nubwiza. Hasi ya viscosity, niko gukomera.

3.

4. Gele yubushyuhe: Iyo ibicuruzwa byamazi ya HEMC bishyushye mubushyuhe runaka, bihinduka opaque, geles, nubushyuhe, ariko iyo bikomeje gukonjeshwa, bisubira muburyo bwambere bwo gukemura, kandi gel hamwe nubushyuhe bibaho. Ubushyuhe ahanini bushingiye kumavuta, amavuta yo guhagarika, colloide ikingira, emulisiferi, nibindi.

5. Ubusembure bwa metabolike numunuko muke nimpumuro nziza: HEMC ikoreshwa cyane mubiribwa nubuvuzi kuko itazahinduka kandi ifite impumuro nziza nimpumuro nziza.

6. Kurwanya ibibyimba: HEMC ifite imbaraga zo kurwanya indwara yoroheje kandi ihagaze neza mugihe cyo kubika igihe kirekire.

Gushyira mu bikorwa: Hydroxyethyl methylcellulose irashobora gukoreshwa nkumuti urinda colloidal, emulifier na dispersant bitewe nubuso bukora mubisubizo byamazi. Ingero zayo zikoreshwa nizi zikurikira: ingaruka za hydroxyethyl methylcellulose kumikorere ya sima. Hydroxyethyl methylcellulose ni ifu yera itagira impumuro nziza, itaryoshye, idafite uburozi ishobora gushonga mumazi akonje kugirango ibe igisubizo kiboneye. Ifite ibiranga kubyimba, guhambira, gutatanya, kwigana, gukora firime, guhagarika, adsorbing, gell, hejuru yubutaka, kubungabunga ubushuhe no kurinda colloid. Kubera ko igisubizo cyamazi gifite imikorere igaragara hejuru, irashobora gukoreshwa nkumuti urinda colloidal, emulifier na dispersant. Hydroxyethyl methylcellulose igisubizo cyamazi gifite hydrophilique nziza kandi nikintu cyiza cyo gufata amazi.
