1. Lo lus nug: Yuav ua li cas yog qhov tsawg-viscosity, nruab nrab-viscosity, thiab high-viscosity txawv ntawm cov qauv, thiab puas yuav muaj qhov sib txawv ntawm qhov sib xws?
Teb:
Nws tau nkag siab 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 haum rau qhov sib txawv viscosity. Tib qhov concentration muaj qhov sib txawv viscosity, khoom ruaj khov thiab acid piv. Kev sib raug zoo ncaj qha feem ntau yog nyob ntawm qhov kev daws teeb meem ntawm cov khoom.
2. Lo lus nug: Dab tsi yog qhov kev ua yeeb yam tshwj xeeb ntawm cov khoom uas muaj qib kev hloov pauv saum toj 1.15, lossis hauv lwm lo lus, qhov siab dua qhov kev hloov pauv, qhov kev ua tau zoo ntawm cov khoom tau txhim kho.
Teb:
Cov khoom muaj kev hloov pauv siab, nce fluidity, thiab txo qis pseudoplasticity. Cov khoom lag luam nrog tib lub viscosity muaj kev hloov pauv siab thiab muaj kev xav pom tseeb dua. Cov khoom uas muaj kev hloov pauv siab muaj cov tshuaj ci ntsa iab, thaum cov khoom uas muaj cov kev hloov pauv dav dav muaj cov tshuaj dawb.
3. Lo lus nug: Puas yog nws zoo rau xaiv qhov nruab nrab viscosity rau fermented protein haus?
Teb:
Cov khoom nruab nrab thiab qis viscosity, qib ntawm kev hloov pauv yog li 0.90, thiab cov khoom uas muaj cov kua qaub zoo dua.
4. Lo lus nug: Yuav ua li cas yuav cmc yaj sai sai? Qee zaum kuv siv nws, thiab nws dissolves maj mam tom qab boiling.
Teb:
Sib tov nrog lwm cov colloids, los yog disperse nrog 1000-1200 rpm agitator. Lub dispersibility ntawm CMC tsis zoo, lub hydrophilicity yog qhov zoo, thiab nws yog ib qho yooj yim rau pawg, thiab cov khoom uas muaj kev hloov pauv qib yog pom tseeb dua! Cov dej sov so sai dua li dej txias. Boiling feem ntau tsis pom zoo. Kev ua noj ua haus ntev ntawm CMC cov khoom yuav rhuav tshem cov qauv molecular thiab cov khoom yuav poob nws cov viscosity!
