Cov teebmeem ntawm Fineness ntawm Dej Retention ntawm Cellulose Ethers

Qhov zoo ntawm cellulose ethers, xws li carboxymethyl cellulose (CMC) thiab hydroxyethyl cellulose (HEC), tuaj yeem cuam tshuam lawv cov dej tuav, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas cov cellulose ethers yog siv los ua thickeners lossis rheology modifiers. Nov yog qee qhov kev cuam tshuam ntawm fineness ntawm kev tuav dej:

1. Qhov Chaw Nto: Cov khoom me me feem ntau muaj thaj tsam loj dua ntawm ib chav tsev loj piv rau cov khoom coarser. Qhov kev nce saum npoo no muab ntau qhov chaw rau kev sib cuam tshuam nrog dej molecules, txhim kho cov dej tuav lub peev xwm ntawm cellulose ether.
2. Dej Rate: Cov khoom me me yuav ua kom dej nrawm dua li cov khoom coarser vim lawv qhov chaw siab dua thiab qhov chaw nkag tau yooj yim dua. Qhov dej sai sai no ua rau tsim cov viscous gel lossis kev daws teeb meem uas khaws cov dej hauv lub cev.
3. Gel Structure: Lub fineness ntawm cellulose ether hais tuaj yeem cuam tshuam cov qauv thiab kev ruaj ntseg ntawm cov gel los yog cov tshuaj thickened tsim nyob rau hauv lub xub ntiag ntawm dej. Cov khoom siv ua kom zoo nkauj yuav ua rau tsim kom muaj kev sib txawv thiab cov khoom siv gel gel ntau dua los ntawm cov roj av hauv lub gel.
4. Dispersion: Cov khoom me me ntawm cellulose ethers zoo li tawg yooj yim dua thiab sib npaug hauv dej los yog lwm yam kua xov xwm piv rau coarser hais. Qhov kev sib cais tsis sib xws no ua kom yooj yim tsim cov tshuaj sib xyaw ua ke los yog dispersion, ua rau cov dej tuav tau zoo thoob plaws hauv lub cev.
5. Compatibility: Cov khoom zoo ntawm cellulose ethers tuaj yeem pom zoo sib xws nrog lwm cov khoom hauv kev tsim, xws li cement, polymers, lossis additives. Qhov kev txhim kho kev sib raug zoo no tso cai rau kev sib cuam tshuam ntau dua thiab muaj txiaj ntsig zoo, txhim kho tag nrho cov dej tuav kev ua tau zoo ntawm cov qauv.
6. Daim Ntawv Thov: Kev ua kom zoo ntawm cellulose ethers tuaj yeem cuam tshuam lawv cov txiaj ntsig hauv ntau txoj kev thov, xws li kev sib xyaw qhuav, ntub dej tawg, lossis sib ntxiv rau cov tshuaj aqueous. Cov khoom me me tuaj yeem tawg tau yooj yim dua thiab sib npaug hauv kev tsim, ua rau kom dej tuav tau zoo dua thaum siv thiab siv tom qab.

Thaum fineness tuaj yeem cuam tshuam zoo rau cov dej tuav cov khoom ntawm cellulose ethers los ntawm kev txhawb nqa sai hydration, uniform dispersion, thiab txhim kho gel tsim, nws yog ib qho tseem ceeb kom sib npaug fineness nrog rau lwm yam xws li viscosity, stability, thiab compatibility kom ua tau zoo kev ua tau zoo nyob rau hauv tej daim ntaub ntawv. Tsis tas li ntawd, qhov xav tau qib ntawm fineness yuav txawv nyob ntawm seb cov kev xav tau thiab kev ua haujlwm ntawm daim ntawv thov.
