Dab tsi yog sodium carboxymethyl cellulose?

Carboxymetylcelleculose (CMC) yog cov tshuaj sib xyaw thiab dav dav siv cov ntawv thov hauv ntau qhov kev lag luam vim nws cov khoom tshwj xeeb. Cov polymer no tau muab los ntawm cellulose, lub ntuj polymer pom nyob hauv cov phab ntsa ntawm tes ntawm cov nroj tsuag. Carboxymethylcellose yog synthesized los ntawm cellulose los ntawm kev qhia ntawm Carboxymethyl pawg thiab thickening muaj peev xwm.

Molecular qauv thiab synthesis

Carboxymethylcellose muaj cov saw hlau cellulose nrog cov pawg carboxymethyl ntawm cov pab pawg hydroxyl ntawm cov dej qab zib. Qhov synthesis ntawm CMC cuam tshuam cov tshuaj tiv thaiv ntawm cellulose acid, uas ua rau lub cev atoms ntawm lub cellulose saw nrog carboxymethyl pawg. Cov degree ntawm kev hloov pauv (DS), uas qhia txog qhov nruab nrab ntawm cov Carboxymethyl ib pawg twg, cuam tshuam rau cov khoom ntawm CMC.

Lub cev thiab tshuaj

1. Solubility: Ib qho ntawm cov ntawv tseem ceeb ntawm CMC yog nws cov dej-solubility, ua rau nws muaj txiaj ntsig thickening tus neeg sawv cev hauv cov kev daws teeb meem aqueous. Cov qib degree hloov tau cuam tshuam rau cov solubility, muaj ntau dua DS ua rau cov dej solubility ntau ntxiv.
2. Viscosity: Carboxymethylcellulose muaj nuj nqis rau nws lub peev xwm los nce viscosity ntawm cov kua. Qhov no ua rau nws muaj cov khoom siv ntau hauv ntau cov khoom, xws li cov khoom noj, cov khoom noj, thiab cov khoom lag luam ntawm tus kheej.
3. Zaj duab xis ua yeeb yam: CMC tuaj yeem tsim cov yeeb yaj kiab thaum ziab, ua rau nws cov ntawv thov hauv cov ntawv luam tawm nyias, yooj yim dua.
4. Ion Txauv: CMC muaj ION pauv pauv cov khoom, tso cai rau nws los cuam tshuam nrog ions hauv kev daws teeb meem. Cov cuab yeej no feem ntau tau siv zog hauv kev lag luam xws li kev kho roj roj thiab khib nyiab.
5. Stability: CMC yog ruaj khov nyob rau hauv ntau ntau ntawm PH cov kev mob, ntxiv rau nws cov versatility hauv cov ntawv thov sib txawv.

Cov Ntawv Thov

1. Kev lag luam khoom noj:

• Tus neeg saib xyuas tuab: CMC yog siv los ua cov tshuaj lom tuab hauv ntau cov khoom noj, suav nrog cov kua ntses, hnav khaub ncaws, thiab khoom noj siv mis.
• Stabilizer: Nws ruaj khov emulsions hauv cov khoom noj khoom haus, tiv thaiv kev sib cais.
• Kev ntxhib los mos hloov kho: CMC txhim kho cov kev ntxhib los mos thiab qhov ncauj ntawm qee yam khoom noj.

2. Kws ua tshuaj paus:

• Binder: CMC yog siv los ua phau ntawv no hauv cov ntsiav tshuaj hauv cov tshuaj, pab tuav cov khoom xyaw ua ke.
• Tus Neeg Sawv Cev Ncua Ntawv: Nws tau ua haujlwm hauv cov tshuaj ua kua los tiv thaiv kev daws teeb meem.

3. Cov khoom lag luam saib xyuas:

• Viscosity Modifier: CMC ntxiv rau cov tshuaj pleev ib ce, tshuaj pleev ib ce, thiab tshuaj pleev kom kho lawv cov viscosity thiab txhim kho lawv cov kev ntxhib.
• Stabilizer: nws ruaj khov emulsions hauv cov tshuaj pleev ib ce.

4. Daim Ntawv Kev Lag Luam:

• Nto sizing tus neeg sawv cev: cmc yog siv hauv cov ntawv lag luam los txhim kho cov khoom ntiag tug ntawm cov ntawv, xws li smoothness thiab printability.

5. Kev lag luam Textile:

• Sizing tus neeg sawv cev: cmc yog thov rau cov fibers los txhim kho lawv cov khoom weaving thiab txhim kho lub zog ntawm lubriced npuag.

6. Roj Drilling:

• Kev tswj cov dej ua haujlwm: CMC tau ua haujlwm hauv cov kua dej drilling kom tswj tau cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm kev ruaj khov.

7. Cov tshuaj khib nyiab:

• Flocculant: CMC ua raws li Flocculant mus rau tej yam zoo sib deev, ua kom lawv raug tshem tawm hauv cov txheej txheem pov tseg.

Ib puag ncig kev txiav txim siab

Carboxymethylcellulose feem ntau suav hais tias muaj kev nyab xeeb rau siv nyob rau hauv ntau yam kev siv. Raws li lub cellulose derivative, nws yog biodegradable, thiab nws qhov cuam tshuam ib puag ncig yog tsawg. Txawm li cas los xij, nws yog qhov tseem ceeb uas yuav tsum xav txog qhov ib puag ncig ib puag ncig ntawm nws kev tsim khoom thiab siv.
