Qhov viscosity ntawm HPMC E5 yog dab tsi?

HPMC E5 yog ib qho uas tsis muaj molecular-yuag hydroxypropyl methylcellulose (HPMC) uas yog siv los ua thickening, suspending, thiab emulsifying tus neeg sawv cev nyob rau hauv ntau yam khoom. Nws yog cov hmoov dawb, tsis muaj ntxhiab, tsis qab, uas yog soluble hauv dej txias thiab insoluble hauv dej kub. Nws yog siv rau ntau yam kev siv, suav nrog zaub mov, tshuaj, thiab tshuaj pleev ib ce.

Lub viscosity ntawm HPMC E5 feem ntau yog ntsuas hauv centipoise (cP). Qhov no yog ib qho kev ntsuas ntawm qhov tsis kam ntawm cov kua ntws, thiab qhia raws li tus nqi ntawm lub siab xav tau kom txav tau ib lub ntim ntawm cov kua ntawm qhov muab ceev. Lub viscosity ntawm HPMC E5 tuaj yeem nyob ntawm 4 txog 6 cP, nyob ntawm qhov concentration ntawm cov tshuaj thiab qhov kub thiab txias.

Ntawm qhov concentration ntawm 1%, viscosity ntawm HPMC E5 feem ntau yog nyob ib ncig ntawm 5 cP. Ntawm qhov concentration ntawm 2%, viscosity nce mus txog 5 cP. Ntawm qhov concentration ntawm 3%, viscosity nce mus txog 5 cP. Ntawm qhov concentration ntawm 4%, viscosity nce mus txog 5 cP.

Hauv cov ntsiab lus, qhov viscosity ntawm HPMC E5 tuaj yeem nyob ntawm 1 txog 100,000 cP, nyob ntawm qhov concentration ntawm cov tshuaj, qhov kub thiab txias, thiab pH. Ntawm qhov concentration ntawm 1%, viscosity feem ntau yog nyob ib ncig ntawm 5 cP. Thaum cov concentrations ntau dua, cov viscosity nce, thiab ntawm qhov kub thiab txias thiab pH siab dua, cov viscosity kuj nce.
