Carboxymethylcellulose (CMC), lub npe hu ua cellulose gum, yog ntau yam thiab dav siv cellulose derivative nrog ntau daim ntawv thov thoob plaws ntau yam lag luam.Cov dej-soluble polymer no yog muab los ntawm cellulose, ib tug natural polymer pom nyob rau hauv lub cell phab ntsa ntawm cov nroj tsuag.Nyob rau hauv qhov kev tshawb nrhiav no, peb delve rau hauv cov qauv ntawm carboxymethylcellulose, nws cov khoom, kev tsim khoom, thiab ntau yam kev siv thoob plaws hauv cov zaub mov thiab dej haus, tshuaj, tshuaj pleev ib ce, textile, thiab lwm yam lag luam.
Cov qauv ntawm Carboxymethylcellulose (CMC):
Carboxymethylcellulose yog tsim los ntawm kev hloov kho cellulose los ntawm etherification thiab carboxymethylation txheej txheem.Cov kev hloov kho no suav nrog kev qhia cov pab pawg carboxymethyl mus rau cov pob txha cellulose.Qhov degree ntawm kev hloov pauv (DS), uas sawv cev rau qhov nruab nrab ntawm cov carboxymethyl pawg ib chav tsev anhydroglucose hauv cellulose, tuaj yeem tswj tau thaum lub sijhawm tsim khoom.Qhov kev hloov kho no qhia cov khoom tshwj xeeb rau CMC, ua rau nws soluble hauv dej thiab tsim nyog rau ntau yam kev siv.
Cov khoom ntawm Carboxymethylcellulose:
1. Dej Solubility:
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm CMC yog nws cov dej solubility.Nws dissolves nyob rau hauv dej los tsim ib tug ntshiab, viscous tov.Cov cuab yeej no muaj txiaj ntsig tshwj xeeb hauv kev lag luam uas nyiam cov txheej txheem dej.
2. viscosity tswj:
CMC paub txog nws lub peev xwm los tswj cov viscosity ntawm aqueous daws.Qhov no ua rau nws yog ib qho tseem ceeb ntawm cov thickening tus neeg sawv cev nyob rau hauv ntau daim ntawv thov, xws li los ntawm cov khoom noj khoom haus mus rau cov tshuaj formulations.
3. Stabilization thiab Suspension:
CMC ua tus stabilizer thiab siv tau los tshem tawm cov khoom hauv cov kua formulations.Qhov no yog ib qho tseem ceeb hauv kev lag luam xws li khoom noj thiab tshuaj, qhov chaw sib faib ntawm cov khoom xyaw tseem ceeb heev.
4. Film-Forming Properties:
CMC nthuav tawm zaj duab xis-tsim cov khoom, ua rau nws muaj txiaj ntsig zoo hauv cov ntawv thov uas tsim cov yeeb yaj kiab nyias nyias yog qhov xav tau.Cov cuab yeej no yog siv rau hauv kev lag luam xws li textiles, qhov twg CMC yog ua hauj lwm nyob rau hauv sizing thiab finishing txheej txheem.
5. Biodegradability:
CMC yog suav tias yog ib puag ncig tus phooj ywg raws li nws tau muab los ntawm cov peev txheej txuas ntxiv mus thiab yog biodegradable.Qhov no ua ke nrog kev loj hlob tseem ceeb ntawm cov khoom siv ruaj khov thiab eco-phooj ywg hauv ntau qhov kev lag luam.
Kev tsim cov txheej txheem ntawm Carboxymethylcellulose:
Kev tsim khoom ntawm CMC suav nrog ntau cov kauj ruam, pib nrog kev xaiv ntawm cov khoom siv cellulose.Ntoo pulp yog ib qho khoom pib siv, txawm tias paj rwb thiab lwm qhov chaw cog ntoo kuj tseem siv tau.Cov cellulose raug rau alkali-catalyzed cov tshuaj tiv thaiv nrog sodium monochloroacetate, ua rau carboxymethylation.Qib ntawm kev hloov pauv yog tswj kom ua tiav cov khoom xav tau rau cov ntawv thov tshwj xeeb.Cov tshuaj tiv thaiv yog ua raws li cov txheej txheem nruab nrab thiab purification kom tau txais cov khoom CMC zaum kawg.
Daim ntawv thov ntawm Carboxymethylcellulose:
1. Kev lag luam zaub mov thiab dej haus:
CMC yog dav siv hauv kev lag luam khoom noj khoom haus ua cov thickener, stabilizer, thiab texturizer.Nws muaj nyob rau hauv cov khoom xws li ice cream, sauces, dressings, thiab ci khoom.Hauv dej haus, CMC yog siv los ua kom ruaj khov thiab tshem tawm cov khoom hauv cov qauv.
2. Pharmaceuticals:
Nyob rau hauv cov tshuaj formulations, CMC ua hauj lwm raws li ib tug binder nyob rau hauv cov ntsiav tshuaj manufacturing, muab cohesiveness rau cov hmoov cov khoom xyaw.Nws kuj tseem siv los ua cov viscosity hloov pauv hauv cov tshuaj ua kua thiab ua tus neeg sawv cev rau kev ncua ntawm qhov ncauj.
3. Cov khoom siv tshuaj pleev ib ce thiab kho tus kheej:
CMC muaj nyob rau hauv ntau yam khoom siv tshuaj pleev ib ce thiab tu tus kheej, nrog rau cov tshuaj pleev, tshuaj pleev, tshuaj zawv plaub hau, thiab tshuaj txhuam hniav.Nws cov thickening thiab stabilizing zog ua rau tag nrho kev ntxhib los mos thiab kev ua tau zoo ntawm cov khoom no.
4. Textiles:
Hauv kev lag luam textile, CMC yog siv rau hauv kev ua haujlwm sizing, qhov uas nws muab lub zog thiab yooj yim rau cov xov paj.Nws kuj yog ua hauj lwm nyob rau hauv cov txheej txheem tiav los tsim ib tug du thiab uniform nto ntawm fabrics.
5. Kev lag luam roj thiab roj:
CMC yog siv rau hauv cov dej drilling hauv kev lag luam roj thiab roj.Nws ua haujlwm raws li lub viscosifier thiab cov kua dej-lossis reducer, pab txhawb kev ruaj ntseg thiab kev ua haujlwm ntawm cov dej drilling hauv cov teeb meem geological nyuaj.
