Amakuru Yibanze ya Hydroxyethyl Methyl Cellulose

Izina ry'ibicuruzwa:hydroxyethyl methyl seluloseHEMC

Izina ry'icyongereza: Hymetellose

Alias: methyl hydroxyethyl selulose; MHEC, hydroxyethyl methyl selulose ether;

hydroxymethyl ethyl selile; 2-hydroxyethyl methyl ether selile

Icyongereza bita: Methylhydroxyethylcellulose; Cellulose; 2-hydroxyethyl methyl ether; HEMC; Tyopur MH [1]

Chimie: Hydroymethylmethylecellulose; Hydroxyethylmethylcellulose; Hydroxymethylethylcellulose.

Molekile: C2H6O2 xCH4O x PhEur 2002 isobanura hydroxyethylmethylcellulose nkigice O-methylated, igice O-hydroxymethylated selile. Ibisobanuro bitandukanye bigaragazwa mubijyanye n'ubukonje bugaragara muri mPa s ya 2% w / v igisubizo cyamazi kuri 20 ° C.

Uburemere bwa molekuline: PhEur 2002 isobanura hydroxyethylmethylcellulose nkigice O-methylated, igice O-hydroxymethylated selile. Ibisobanuro bitandukanye bigaragazwa mubijyanye n'ubukonje bugaragara muri mPa s ya 2% w / v igisubizo cyamazi kuri 20 ° C.

Ibintu nyamukuru biranga hydroxyethyl methyl selulose (HEMC) ni:

1.

3.

4. Gele yubushyuhe: Iyo ibicuruzwa byamazi ya HEMC bishyushye mubushyuhe runaka, bihinduka opaque, geles, kandi bigakora imvura, ariko iyo bikomeje gukonjeshwa, bisubira muburyo bwambere bwo gukemura, kandi iyi gel hamwe nubushyuhe bibaho . Ubushyuhe buterwa ahanini n'amavuta yabo, imfashanyo zihagarika, colloide ikingira, emulisiferi, nibindi.

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

6. Antifungal: HEMC ifite ubushobozi bwiza bwa antifungal hamwe nubwiza bwimitsi myiza mugihe cyo kubika igihe kirekire.

Gushyira mu bikorwa: Hydroxyethyl methyl selulose irashobora gukoreshwa nkibikoresho birinda colloid, emulisiferi na dispersant bitewe nubuso bukora bwibisubizo byamazi. Urugero rwo kubishyira mu bikorwa ni ibi bikurikira: Ingaruka ya hydroxyethyl methyl selulose kumiterere ya sima. Hydroxyethyl methylcellulose ni ifu yera idafite uburyohe, uburyohe, nontoxic ifu yera ishonga mumazi akonje kugirango ibe igisubizo gisobanutse neza. Ifite imiterere yo kubyimba, guhambira, gutatanya, kwigana, gukora firime, guhagarika, adsorbing, gell, gukora-hejuru, kugumana ubushuhe no kurinda colloide. Bitewe nubuso bukora bwibikorwa byamazi yo mumazi, birashobora gukoreshwa nkibikoresho birinda colloid, emulifier na dispersant. Hydroxyethyl methyl selulose yumuti wamazi ufite hydrophilique nziza kandi nikintu cyiza cyane cyo kubika amazi.
