Sodium carboxymethyl selile

Intangiriro

Carboxymethyl selulose (CMC) ni ubwoko bwa selile ikomoka kuri selile ikomoka kuri selile na carboxymethylation. Ni ifu yera, idafite impumuro nziza, idafite uburyohe ikoreshwa cyane mubiribwa, imiti, imiti yo kwisiga, nizindi nganda. CMC ni polymer-amazi-elegitoronike polymer ifite uburyo bwinshi bwo gukoresha kubera imiterere yihariye. Ikoreshwa nkibikoresho byibyimbye, stabilisateur, emulifier, hamwe nu guhagarika ibikorwa. CMC ikoreshwa kandi nka colloid ikingira mugukora impapuro nimyenda.

Imiterere

Imiterere ya carboxymethyl selulose (CMC) igizwe numurongo ugizwe na molekile ya glucose ihujwe hamwe na glycosidic. Molekile ya glucose ihujwe na atome imwe ya ogisijeni, ikora urunigi rw'umurongo. Urunigi rw'umurongo noneho rwitwa carboxymethylated, bivuze ko itsinda rya carboxymethyl (CH2COOH) ryometse kumatsinda ya hydroxyl (OH) ya molekile ya glucose. Iyi carboxymethylation inzira itera molekile ya carboxymethyl selile yuzuye nabi.

Imiterere ya carboxymethyl selulose irashobora kugaragazwa na formula ikurikira:

(C6H10O5) n-CH2COOH

aho n ni urwego rwo gusimbuza (DS) rwitsinda rya carboxymethyl. Urwego rwo gusimbuza numubare wamatsinda ya carboxymethyl kuri molekile ya glucose. Urwego rwo hejuru rwo gusimburana, niko hejuru ya viscosity yumuti wa CMC.

Ibyiza Carboxymethyl selulose ifite umubare wimiterere yihariye ituma iba ingirakamaro mubikorwa bitandukanye. Ni polymer-eruble polymer ihagaze neza mubisubizo byamazi. Ntabwo kandi ari uburozi, ntiburakaza, kandi ntabwo allerge. CMC nayo irwanya kwangirika kwa mikorobe kandi ntabwo iterwa na pH cyangwa ubushyuhe. CMC ni ikintu gikomeye cyane kandi gishobora gukoreshwa mu kubyimba amazi atandukanye, harimo ibiryo, imiti, hamwe no kwisiga. Irakoreshwa kandi nka emulisiferi, stabilisateur, hamwe nu guhagarika ibikorwa. CMC ikoreshwa kandi nka colloid ikingira mugukora impapuro nimyenda. Umwanzuro Carboxymethyl selulose (CMC) ni ubwoko bwa selile ikomoka kuri selile ikomoka kuri selile na carboxymethylation. Ni ifu yera, idafite impumuro nziza, idafite uburyohe ikoreshwa cyane mubiribwa, imiti, imiti yo kwisiga, nizindi nganda. CMC igizwe numurongo umwe wa molekile ya glucose ihujwe hamwe na glycosidic bond na carboxymethylated. Ifite umubare wimiterere yihariye ituma igira akamaro mubikorwa bitandukanye. CMC nikintu gikomeye cyo kubyimba kandi gishobora gukoreshwa nka emulisiferi, stabilisateur, hamwe nu guhagarika ibikorwa. Ikoreshwa kandi nka colloid ikingira mugukora impapuro nimyenda.
