Qhov Zoo ntawm Cov Tsev Tshuaj HPMC

HPMC HydroxyPropyyl methylculose tau dhau los ua ib qho ntawm cov tshuaj uas muaj kev cia siab hauv tsev thiab txawv teb chaws, vim tias HPMC muaj qhov zoo uas tsis muaj kev cia siab.

1. Dej Solubility

Nws yog soluble nyob rau hauv dej txias hauv qab 40 ℃ lossis 70% ethanol, thiab nws yog qhov tseem insoluble hauv dej kub saum 60 ℃, tab sis nws tuaj yeem gelled.

2. Tshuaj inert

HPMC yog hom tsis muaj ionic cellulose ether. Nws cov kev daws teeb meem tsis nqa ib qho kev them nqi ionic thiab tsis cuam tshuam nrog cov kav hlau hlau lossis ionic organic sib txuas. Yog li ntawd, lwm yam kev zam tsis yog kev tawm tsam nrog nws thaum lub sijhawm npaj.

3. Kev ruaj khov

Nws yog qhov ruaj khov rau cov kua qaub thiab alkali, thiab tuaj yeem khaws cia ntev li ntawm PH 3 ~ 11, thiab nws cov viscosity tsis muaj kev hloov pauv. Cov tshuaj aqueous ntawm HPMC muaj cov nyhuv anti-mildew effect thiab tuaj yeem tswj cov viscosity zoo thaum lub sijhawm ntev cia. Cov tshuaj uas tau siv tshuaj siv HPMC muaj cov khoom ruaj khov zoo dua li cov uas siv cov khoom siv tshuaj lom neeg (xws li Dextrin, cov hmoov txhuv nplej siab, thiab lwm yam).

4. Kev kho tau ntawm viscosity

Qhov txawv viscosity ntawm HPMC tuaj yeem sib xyaw nrog cov cai sib txawv, thiab nws txoj kev viscosity zoo, yog li nws tuaj yeem xaiv raws li qhov kev thov. 2.5 metabolic inertia HPMC tsis tau nqus lossis metabolized hauv lub cev, thiab tsis muab calories, yog li nws yog kev nyab xeeb rau kev npaj tshuaj. Cov.

5. Kev ruaj ntseg

Nws yog feem ntau suav tias HPMC yog cov khoom tsis muaj tshuaj lom thiab tsis yog-khaus.

Kws nqa tshuaj-qib HPMC yog cov khoom siv tseem ceeb rau kev tsim cov kev txhawb nqa thiab tswj kev tso tawm kev npaj. Nws yog cov tshuaj uas ib qho kev zam txhawb nqa los ntawm lub xeev rau kev tshawb fawb thiab kev txhim kho, thiab yog nyob rau hauv txoj kab nrog kev txhim kho kev txhawb nqa los ntawm kev tsim kev lag luam hauv tebchaws. Kws nqa tshuaj-qib HPMC yog cov khoom siv tseem ceeb rau kev tsim cov tshuaj hpmc Cov tshuaj cansules nroj tsuag tsim muaj qhov zoo ntawm kev nyab xeeb thiab kev pheej hmoo, tsis muaj kev phom sij, thiab siab ruaj khov, uas yog nyob rau hauv txoj kab nrog cov kev cia siab. Cov khoom noj muaj kev nyab xeeb thiab kev nyab xeeb yuav tsum muaj ib qho khoom siv tseem ceeb thiab cov khoom siv zoo rau cov tsiaj txhu cov ntsiav tshuaj.
