Hydroxypropyl methylcellulose tsis muaj teeb meem rau tib neeg lub cev, hydroxypropyl methyl cellulose muaj kev nyab xeeb thiab tsis muaj kuab lom, tuaj yeem siv ua khoom noj ntxiv, tsis muaj cua sov, thiab tsis muaj kev ua kom tawv nqaij rau cov tawv nqaij thiab hnoos qeev. Feem ntau suav tias yog qhov muaj kev nyab xeeb txhua hnub rau kev tso cai ntawm 25mg / kg, cov khoom tiv thaiv yuav tsum hnav thaum lub sijhawm ua haujlwm.

Cov poj niam pub niam mis rau lactate thaum siv tshuaj, thiab tsis muaj qhov tshwm sim tsis zoo hauv cov menyuam mos. Yog li no, tsis muaj cov qauv tshwj xeeb rau cov poj niam cev xeeb tub thiab lactating. Kev siv cov hypromellose hauv cov menyuam yaus tsis ua rau muaj kev phiv tshuaj ntau dua li piv nrog lwm pab pawg hnub nyoog, yog li cov menyuam yaus tuaj yeem siv cov khoom no hauv cov txheej txheem ib yam li cov neeg laus.

Cov yam ntxwv ntawm hydroxypropyl methylcellulose

1. Cov qib siab dua ntawm polymerization ntawm cellulose ether, qhov loj dua nws cov phaus molecular, thiab ntau dua cov viscosity ntawm cov kua aqueous.

2. Qhov ua kom tau ntau dua (lossis cov concentration) ntawm cov cellulose ether, ntau dua lub viscosity ntawm nws cov kua tov. Txawm li cas los xij, xyuam xim rau kev xaiv qhov kev xaiv kom tsim nyog thaum lub sij hawm thov kom tsis txhob noj ntau dhau thiab muaj kev cuam tshuam cov haujlwm ntawm pob zeb thiab pob zeb ua. tus yam ntxwv.

3. Raws li nrog feem ntau cov kua, lub viscosity ntawm cellulose ether kev daws teeb meem yuav tsawg zuj zus nrog qhov kub nce zuj zus, thiab ntau dua qhov kev kub siab ntawm cellulose ether, cov nyhuv kub ntau dua.

4. Hydroxypropyl methylcellulose kua feem ntau yog pseudoplastic lub cev, uas muaj cov cuab yeej ntawm shear thinning. Qhov ntau dua ntawm cov khoom txiav thaum ntsuas, qhov qis dua viscosity. Yog li ntawd, qhov sib haum ntawm qhov cug yuav txo qis vim qhov quab yuam sab nraud, uas yog qhov tsim nyog rau qhov kev tsim kho ntawm qhov caws, ua rau cov tshuaj khib muaj qhov zoo ntawm kev ua haujlwm thiab cohesiveness.

Kev daws teeb meem hydroxypropyl methylcellulose ua rau pom Newtonian kua cov yam ntxwv thaum qhov siab poob qis thiab viscosity yog tsawg. Thaum cov concentration muaj ntau ntxiv, txoj kev daws maj mam nthuav qhia cov kua pseudoplastic cov yam ntxwv, thiab qhov siab dua, kev cuam tshuam ntau dua pseudoplasticity.
