Txoj kev los tiv thaiv Caking Thaum Dissolving CMC

Tiv thaiv caking thaum dissolving sodium carboxymethyl cellulose (CMC) koom nrog cov txheej txheem tuav kom zoo thiab siv cov txheej txheem tsim nyog los xyuas kom meej cov dispersion thiab dissolution. Nov yog qee txoj hauv kev los tiv thaiv caking thaum dissolving CMC:

1. Kev npaj daws teeb meem:
   • Maj mam ntxiv CMC hmoov rau cov kua theem thaum stirring tsis tu ncua kom tiv thaiv clumping thiab xyuas kom meej txawm wetting ntawm hais.
   • Siv lub tshuab sib tov, tov khoom, los yog cov khoom sib tov sib xyaw ua kom tawg CMC hmoov sib npaug hauv cov kua theem, rhuav tshem cov agglomerates thiab txhawb kev tawg sai.
2. Kev tswj qhov kub thiab txias:
   • Khaws qhov ntsuas kub nyob rau hauv qhov kev pom zoo rau CMC dissolution. Feem ntau, cua sov cov dej mus rau ib ncig ntawm 70-80 ° C tuaj yeem ua kom yooj yim tawg ntawm CMC.
   • Tsis txhob siv qhov kub thiab txias ntau dhau, vim qhov no yuav ua rau CMC cov tshuaj gel los yog ua pob.
3. Lub Sijhawm Dej:
   • Cia lub sij hawm txaus rau hydration thiab dissolution ntawm CMC hais nyob rau hauv cov tshuaj. Nyob ntawm seb qhov luaj li cas thiab qib ntawm CMC, qhov no yuav muaj li ntawm ob peb feeb mus rau teev.
   • Do cov tshuaj intermittently thaum lub sij hawm hydration kom zoo dispersion thiab tiv thaiv kev daws ntawm undissolved hais.
4. Kev hloov pH:
   • Xyuas kom meej tias pH ntawm cov tshuaj yog nyob rau hauv qhov kev pom zoo rau CMC dissolution. Feem ntau CMC qib yaj zoo tshaj plaws nyob rau hauv me ntsis acidic rau nruab nrab pH tej yam kev mob.
   • Kho cov pH ntawm cov tshuaj siv cov kua qaub los yog cov hauv paus raws li qhov xav tau los txhawb kom muaj txiaj ntsig zoo ntawm CMC.
5. Kev ntxhov siab:
   • Agitate cov tshuaj tsis tu ncua thaum lub sij hawm thiab tom qab CMC ntxiv los tiv thaiv kev daws thiab caking ntawm undissolved hais.
   • Siv txhua yam agitation los yog nplawm kom muaj homogeneity thiab txhawb nqa kev faib tawm ntawm CMC thoob plaws hauv cov tshuaj.
6. Particle loj txo:
   • Siv CMC nrog qhov me me me me, vim tias cov khoom me me yuav yaj tau yooj yim dua thiab tsis yooj yim rau caking.
   • Xav txog pre-dispersed los yog pre-hydrated CMC formulations, uas yuav pab tau kom txo tau txoj kev pheej hmoo ntawm caking thaum lub sij hawm dissolution.
7. Kev cia khoom:
   • Khaws CMC hmoov rau hauv qhov chaw txias, qhuav kom deb ntawm cov dej noo thiab cov av noo kom tsis txhob clumping thiab caking.
   • Siv cov ntaub ntawv ntim khoom tsim nyog, xws li cov hnab ntim dej los yog cov thawv ntim khoom, los tiv thaiv CMC hmoov los ntawm ib puag ncig noo noo.
8. Kev Tswj Xyuas Zoo:
   • Xyuas kom meej tias CMC hmoov ua tau raws li cov lus qhia me me, purity, thiab noo noo cov ntsiab lus kom txo qhov kev pheej hmoo ntawm caking thaum lub sij hawm dissolution.
   • Ua cov kev ntsuam xyuas zoo, xws li kev ntsuas viscosity lossis kev kuaj pom, txhawm rau ntsuas qhov sib xws thiab qhov zoo ntawm cov tshuaj CMC.

Los ntawm kev ua raws li cov txheej txheem no, koj tuaj yeem tiv thaiv caking zoo thaum so sodium carboxymethyl cellulose (CMC), kom ntseeg tau tias du thiab zoo li dispersion ntawm cov polymer hauv cov tshuaj. Kev tuav tswj kom zoo, tswj qhov kub thiab txias, lub sij hawm hydration, pH hloov, agitation, particle loj txo, cia tej yam kev mob, thiab kev tswj kom zoo yog yam tseem ceeb nyob rau hauv kev ua kom pom zoo dissolution ntawm CMC tsis muaj caking.
