Cov lus teb rau cov lus nug hauv kev siv CMC

1. Lo lus nug: Qhov sib txawv ntawm cov khoom uas muaj viscosity tsawg, viscosity nruab nrab, thiab viscosity siab yog dab tsi, thiab puas yuav muaj qhov sib txawv ntawm qhov sib xws?

Teb:

Nws to taub tias qhov ntev ntawm cov saw hlau molecular txawv, lossis qhov hnyav molecular txawv, thiab nws muab faib ua qis, nruab nrab thiab siab viscosity. Tau kawg, qhov kev ua tau zoo macroscopic sib raug rau qhov sib txawv viscosity. Tib qhov concentration muaj viscosity sib txawv, cov khoom ruaj khov thiab acid piv. Qhov kev sib raug zoo ncaj qha feem ntau nyob ntawm qhov kev daws teeb meem ntawm cov khoom.

2. Lo lus nug: Cov kev ua tau zoo tshwj xeeb ntawm cov khoom uas muaj qib hloov pauv siab dua 1.15 yog dab tsi, lossis hais lwm yam, qib hloov pauv siab dua, qhov kev ua tau zoo tshwj xeeb ntawm cov khoom tau txhim kho.

Teb:

Cov khoom muaj qib siab ntawm kev hloov pauv, nce fluidity, thiab txo qis pseudoplasticity. Cov khoom uas muaj tib lub viscosity muaj qib siab ntawm kev hloov pauv thiab pom tseeb dua qhov kev xav nplua. Cov khoom uas muaj qib siab ntawm kev hloov pauv muaj cov kua ci ntsa iab, thaum cov khoom uas muaj qib dav dav ntawm kev hloov pauv muaj cov kua dawb.

3. Lo lus nug: Puas yog nws zoo rau xaiv qhov nruab nrab viscosity rau cov dej haus protein fermented?

Teb:

Cov khoom lag luam viscosity nruab nrab thiab qis, qib kev hloov pauv yog li 0.90, thiab cov khoom lag luam uas muaj kev tiv thaiv acid zoo dua.

4. Lo lus nug: Yuav ua li cas cmc thiaj yaj sai? Kuv qee zaum siv nws, thiab nws yaj qeeb tom qab npau.

Teb:

Sib tov nrog lwm cov colloids, lossis sib tov nrog 1000-1200 rpm agitator. Qhov dispersibility ntawm CMC tsis zoo, hydrophilicity zoo, thiab nws yooj yim rau cluster, thiab cov khoom nrog high substitution degree yog pom tseeb dua! Dej sov yaj sai dua li dej txias. Boiling feem ntau tsis pom zoo. Kev ua noj ntev ntawm CMC cov khoom yuav rhuav tshem cov qauv molecular thiab cov khoom yuav poob nws cov viscosity!
