Dab tsi yog qhov cuam tshuam rau viscosity ntawm hydroxypropyl methylcellulose?

Daim ntawv thov ntawm hydroxypropyl methylcellulose yog qhov dav heev, thiab nws muaj ntau yam ua rau nws cov viscosity, thiab cov viscosity xav tau rau kev siv sib txawv ntawm hydroxypropyl methylcellulose kuj txawv, yog li thaum peb siv nws cov khoom ua ntej, peb yuav tsum paub tias nws cov viscosity yog dab tsi. yog, tab sis viscosity ntawm hydroxypropyl methylcellulose cuam tshuam los ntawm ntau yam. Yog tias qhov chaw cia tsis ceev faj, nws yuav ua rau nws cov viscosity poob. Yog li rau hydroxypropyl methylcellulose, Dab tsi yog nws cov viscosity ntsig txog? Cia kuv qhia koj luv luv.

Feem ntau, viscosity ntawm hydroxypropyl methylcellulose yuav raug cuam tshuam los ntawm cov hauv qab no:

1. Qhov siab dua ntawm polymerization ntawm cellulose ether thiab qhov loj dua qhov hnyav molecular, qhov siab dua qhov viscosity ntawm nws cov kua aqueous;

2. Qhov ntau npaum li cas (lossis concentration) ntawm cellulose ether, qhov siab dua qhov viscosity ntawm nws cov kua aqueous, tab sis kev saib xyuas yuav tsum tau coj los xaiv qhov tsim nyog npaum li cas thaum siv nws, thiaj li tsis cuam tshuam rau kev ua haujlwm ntawm mortar thiab pob zeb yog tias lub noj ntau dhau lawm;

3. Zoo li feem ntau cov kua dej, cov viscosity ntawm cellulose ether daws yuav txo qis nrog qhov kub thiab txias, thiab qhov siab dua ntawm cov cellulose ether, qhov kub ntawm qhov kub yuav ntau dua;

Feem ntau, thaum peb tswj cov viscosity ntawm hydroxypropyl methylcellulose, peb saib los ntawm cov ntsiab lus saum toj no, yog li peb yuav tsum xyuas thiab siv nws ntau zaus thaum khaws cia hydroxypropyl methylcellulose.
