Carboxymethyl cellulose fiber ntau

 

 

  Carboxymethyl cellulose (CMC) yog ib qho ntau yam dav siv nyob rau ntau cov khoom lag luam los ntawm cov zaub mov noj thiab cov tshuaj. Nws yog qhov ua kom pom tseeb ntawm cellulose, uas yog lub ntuj muaj zog nyob hauv cov phab ntsa ntawm tes. CMC yog tsim los ntawm kev kho cellulose nrog chloroacetic acid thiab qhia cov pab pawg carboxymethyl mus rau lub cellulose pawg.
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm CMC yog tias nws tuaj yeem tsim lub viscous gel thaum sib xyaw nrog dej. Qhov no ua rau nws muaj txiaj ntsig zoo rau hauv ntau yam kev siv, xws li hauv cov khoom lag luam xws li cov mis nyuj khov, kua ntses, thiab nyias nyias. CMC kuj tseem siv tau ua cov stabilizer rau cov dej khov thiab cov khoom noj qab zib khov, pab tiv thaiv kev sib cais ntawm cov khoom sib cais.
Ntxiv rau nws cov khoom siv tuab thiab ruaj khov, cmc kuj yog cov siv uas siv tau siv ntau. Qhov no txhais tau tias nws tuaj yeem pab sib xyaw kom tsis txhob muaj kev sib xyaw xws li roj thiab dej ua ke. Qhov no ua rau CMC ib qho tseem ceeb xyaw ua ke xws li mayonnaise thiab margarine.

- Cov qauv tshuaj lom neeg: chav tsev hydroxyl (-H) ntawm cov pab pawg qab zib ntawm cov roj hmab yog hloov los ntawm cov pab pawg carboxymethyl (-ch {3}}. 6 ~ 1.2.
- Solubility: Yooj yim soluble hauv dej, insoluble hauv cov kuab tshuaj ethanol (xws li ethanol, acetone).
- Cov Khoom Siv Tau Txuj Ci:
- Cov viscosity siab (nyob ntawm seb muaj kev hnyav thiab qib siab hloov chaw).
- P PAUB: ruaj khov nyob rau hauv lub Ph Thaj Tsam ntawm 3 ~ 12, thiab nag lossis daus yuav tshwm sim yog tias cov kua qaub dhau (ph <3).
- Cov ntsev tsis kam: May Gel nyob rau hauv cov cawv ntawm cov neeg muaj feem ntau ntawm cov hlau ions (ca²⁺, al³⁺).
- Biocompatibility: tsis-toxic, tsis-irritating, biodegradable (tab sis qhov kev cuam tshuam yog qeeb).

Qhov chaw cia rau CMC Cellulose feem ntau xav tau qhov chaw txias, qhuav, thiab muaj qhov cua, tsis txhob muaj hnub ci thiab kub. Tshwj xeeb, nws yuav tsum tau muab cia rau hauv ib puag ncig ntawm 2-8 degree c thiab zam rau kev sib cuag nrog dej lossis noo noo los tiv thaiv clumping los yog xaus. Ib qho ntxiv, txhawm rau tswj nws cov kev ua tau zoo, tiv tauj nrog cov oxidants muaj zog yuav tsum tau zam.
