Iimpendulo kwimibuzo ekusetyenzisweni kweCMC

1. Umbuzo: I-low-viscosity, i-medium-viscosity, kunye ne-high-viscosity ihluke njani kwisakhiwo, kwaye ngaba kuya kubakho ukungafani kokuhambelana?

Phendula:

Kuyaqondwa ukuba ubude betsheyini ye-molecular buhluke, okanye ubunzima be-molecular buhluke, kwaye buhlulwe kwi-viscosity ephantsi, ephakathi kunye nephezulu. Ngokuqinisekileyo, ukusebenza kwe-macroscopic kuhambelana ne-viscosity eyahlukileyo. Ukugxininiswa okufanayo kune-viscosity eyahlukileyo, ukuzinza kwemveliso kunye nomlinganiselo we-asidi. Ulwalamano oluthe ngqo luxhomekeke kwisisombululo semveliso.

2. Umbuzo: Zeziphi iintsebenzo ezithile zeemveliso ezineqondo lokutshintshwa ngaphezulu kwe-1.15, okanye ngamanye amazwi, iqondo eliphezulu lokutshintshwa, ukusebenza okuthe ngqo kwemveliso kuye kwandiswa.

Phendula:

Imveliso inezinga eliphezulu lokutshintshwa, ukunyuka kwamanzi, kunye nokunciphisa kakhulu i-pseudoplasticity. Iimveliso ezine-viscosity efanayo zinezinga eliphezulu lokuthatha indawo kunye nemvakalelo ecacileyo yokutyibilika. Iimveliso ezinomgangatho ophezulu wokutshintshwa zinesisombululo esikhanyayo, ngelixa iimveliso ezinezinga eliqhelekileyo lokutshintshwa zinesisombululo esimhlophe.

3. Umbuzo: Ngaba kulungile ukukhetha i-viscosity ephakathi kwiziselo zeprotheyini ezivundisiweyo?

Phendula:

Imveliso ye-viscosity ephakathi kunye nephantsi, iqondo lokutshintshwa malunga ne-0.90, kunye neemveliso ezinokumelana ne-asidi engcono.

4. Umbuzo: I-cmc inokunyibilika njani ngokukhawuleza? Ngamanye amaxesha ndiyayisebenzisa, kwaye inyibilika kancinane emva kokubilisa.

Phendula:

Hlanganisa kunye nezinye iicolloids, okanye usasaze nge-1000-1200 rpm agitator. I-dispersibility ye-CMC ayilunganga, i-hydrophilicity ilungile, kwaye kulula ukuhlanganisana, kwaye iimveliso ezinezinga eliphezulu lokuthatha indawo zibonakala ngakumbi! Amanzi ashushu anyibilika ngokukhawuleza kunamanzi abandayo. Ukubilisa ngokubanzi akukhuthazwa. Ukupheka kwexesha elide kweemveliso ze-CMC kuya kutshabalalisa isakhiwo se-molecular kwaye imveliso iya kulahlekelwa yi-viscosity yayo!
