Ibanze shingiro no gutondekanya Cellulose Ether

Ether ya selulose ni icyiciro cya polymer zishonga amazi zikomoka kuri selile, polymer karemano iboneka murukuta rw'utugingo ngengabuzima.Zikoreshwa cyane mubikorwa bitandukanye byinganda bitewe nimiterere yihariye nko gukemura amazi, ubushobozi bwo gukora firime, hamwe nubunini.Ibitekerezo byibanze no gutondekanya selile ya selile ni ibi bikurikira:

1. Imiterere ya Cellulose: Cellulose ni polymer y'umurongo ugizwe no gusubiramo ibice bya molekile ya glucose ihujwe na β-1,4-glycosidic.Ibice bya glucose bitondekanye mumurongo umwe, bigahuzwa na hydrogen ihuza iminyururu yegeranye.Urwego rwa polymerisation ya selile iratandukanye bitewe ninkomoko kandi irashobora kuva ku magana make kugeza ku bihumbi byinshi.

2. Inkomoko ya selile ya selile: Ethers ya selile ikomoka kuri selile ihindura imiti.Ubwoko bwa ethers ya selile ikunze kuboneka harimo methylcellulose (MC), hydroxypropyl methylcellulose (HPMC), Ethylcellulose (EC), carboxymethyl selulose (CMC), nibindi.Buri bwoko bwa selile ether ifite imiterere yihariye nibisabwa.

3. Gutondekanya Ethers ya Cellulose: Ethers ya selile irashobora gushyirwa mubyiciro bitewe nurwego rwabo rwo gusimbuza (DS), numubare wamatsinda asimburanya kuri glucose.DS ya selulose ethers igena gukomera kwayo, ubwiza, nibindi bintu.Kurugero, MC na HPMC hamwe na DS nkeya birashobora gushonga amazi kandi bigakoreshwa nkibibyimbye, mugihe EC ifite DS ndende idashobora gushonga mumazi kandi ikoreshwa nkibikoresho byo gutwikira.

4. Gushyira mu bikorwa Ethers ya Cellulose: Ethers ya selile ifite uburyo bwinshi bwo gukoresha mubiribwa, imiti, amavuta yo kwisiga, nubwubatsi.Zikoreshwa nkibibyimbye, stabilisateur, emulisiferi, binders, hamwe nibikoresho bikora firime.Kurugero, HPMC ikoreshwa nkibyimbye mubicuruzwa byibiribwa, CMC ikoreshwa nkibikoresho mu miti ya farumasi, naho MC ikoreshwa nkibikorwa byo gukora firime mubicuruzwa byo kwisiga.

Mugusoza, selile ethers ni polymers zitandukanye zifite imiterere yihariye nibisabwa.Gusobanukirwa ibitekerezo byabo byibanze no gutondeka birashobora gufasha muguhitamo selile ikwiye ya ether kubisabwa byihariye.
