Yuav Siv Sodium CMC li cas

Sodium Carboxymethyl Cellulose (Na-CMC) yog ntau yam dej-soluble polymer nrog ntau daim ntawv thov thoob plaws ntau yam kev lag luam. Nov yog cov lus qhia dav dav txog kev siv Na-CMC:

1. Xaiv Na-CMC Qib:

• Xaiv cov qib uas tsim nyog ntawm Na-CMC raws li koj qhov kev thov tshwj xeeb. Xav txog yam xws li viscosity, purity, particle loj, thiab compatibility nrog rau lwm cov khoom xyaw.

2. Kev Npaj Na-CMC Solution:

• Dissolve qhov xav tau ntawm Na-CMC hmoov nyob rau hauv dej los npaj ib homogeneous tov. Siv cov dej deionized los yog distilled kom pom cov txiaj ntsig zoo.
• Pib los ntawm kev ntxiv Na-CMC maj mam rau hauv dej thaum nplawm tas li txhawm rau tiv thaiv cov pob los yog pob tsim.
• Txuas ntxiv mus kom txog thaum Na-CMC yog yaj tag, thiab cov tshuaj zoo li pom tseeb thiab zoo ib yam. Cua sov cov dej tuaj yeem ua kom cov txheej txheem tawg yog tias xav tau, tab sis zam dhau qhov kub thiab txias uas yuav ua rau Na-CMC degrade.

3. Kev Kho Kom Zoo:

• Txiav txim siab npaum li cas ntawm Na-CMC raws li koj daim ntawv thov tshwj xeeb thiab cov yam ntxwv uas xav tau. Xa mus rau cov khoom tshwj xeeb lossis ua qhov kev sim ua ntej txhawm rau txhim kho Na-CMC ntau npaum.
• Qhov ntau npaum li cas ntawm Na-CMC yog li ntawm 0.1% mus rau 2.0% los ntawm qhov hnyav ntawm tag nrho cov qauv, nyob ntawm daim ntawv thov thiab xav tau viscosity.

4. Sib tov nrog lwm cov khoom xyaw:

• Muab cov tshuaj Na-CMC tso rau hauv koj cov qauv tsim thaum lub sijhawm sib xyaw.
• Ntxiv cov tshuaj Na-CMC maj mam thaum agitating qhov sib tov kom ntseeg tau tias muaj kev faib tawm.
• Sib tov kom huv si kom txog thaum Na-CMC sib npaug sib npaug thoob plaws hauv kev tsim.

5. Kev hloov ntawm pH thiab kub (yog tias tsim nyog):

• Saib xyuas pH thiab qhov kub thiab txias ntawm cov tshuaj thaum npaj, tshwj xeeb tshaj yog yog Na-CMC rhiab rau pH lossis kub.
• Kho cov pH raws li qhov xav tau siv cov buffers tsim nyog lossis alkalizing cov neeg ua haujlwm txhawm rau txhim kho Na-CMC kev ua tau zoo. Na-CMC yog qhov zoo tshaj plaws nyob rau hauv me ntsis alkaline tej yam kev mob (pH 7-10).

6. Kev Tswj Xyuas Zoo:

• Ua cov kev ntsuam xyuas zoo ntawm cov khoom kawg los ntsuas qhov ua tau zoo ntawm Na-CMC.
• Cov ntsuas ntsuas yuav suav nrog ntsuas viscosity, ntsuas kev ruaj ntseg, rheological zog, thiab tag nrho cov khoom ua tau zoo.

7. Cia thiab tuav:

• Khaws Na-CMC hmoov rau hauv qhov chaw txias, qhuav kom deb ntawm tshav ntuj ncaj qha thiab ya raws.
• Tuav Na-CMC cov kev daws teeb meem nrog kev saib xyuas kom tsis txhob muaj kev sib kis thiab tswj xyuas cov khoom ncaj ncees.
• Ua raws li cov lus qhia txog kev nyab xeeb thiab kev ceev faj hauv cov ntaub ntawv kev nyab xeeb cov ntaub ntawv (MSDS) muab los ntawm cov chaw tsim khoom.

8. Daim ntawv thov tshwj xeeb xav txog:

• Nyob ntawm daim ntawv thov npaj, kev hloov kho ntxiv lossis kev txiav txim siab yuav tsim nyog. Piv txwv li, hauv cov khoom noj khoom haus, xyuas kom Na-CMC ua raws li cov qauv kev cai thiab cov txheej txheem.

Los ntawm kev ua raws li cov lus qhia dav dav no, koj tuaj yeem siv Sodium Carboxymethyl Cellulose (Na-CMC) tau zoo hauv ntau daim ntawv thov thaum txhim kho nws cov kev ua tau zoo thiab kev ua haujlwm. Cov kev hloov pauv yuav xav tau raws li cov cai tshwj xeeb thiab cov xwm txheej tshwj xeeb rau txhua daim ntawv thov.
