Tsuas yog txiav txim siab qhov zoo ntawm hydroxypropyl methylcellulose

Hydroxypropyl methylcellulosemuaj cov yam ntxwv ua kom tuab, khi, tawg, emulsifying, zaj duab xis-tsim, suspending, adsorbing, gelling, surfactant, khaws noo noo thiab tiv thaiv colloid. Ntau yam kev siv dav heev.

Kev zoo nkauj

Qhov fineness ntawm hydroxypropyl methylcellulose feem ntau muaj 80 mesh thiab 100 mesh. Qhov finer qhov fineness, qhov sai dua qhov dissolve, feem ntau hais lus, qhov zoo dua. Feem ntau, cov reactors ntsug tsim cov khoom nyias dua li cov reactors kab rov tav.

Kev Sib Kis

Yaj hydroxypropyl methylcellulose (HPMC) rau hauv dej kom ua kua pob tshab. Saib nws lub teeb ci. Lub teeb ci ntau dua, qhov zoo dua, qhia tias muaj cov insolubles tsawg dua hauv nws.

feem pua

Qhov loj nruab nrab zoo dua. Yog tias qhov hnyav tshwj xeeb loj dhau lossis me dhau, nws yuav yog qhov tshwm sim ntawm kev tswj tsis zoo thaum lub sijhawm tsim khoom.

Sab nraud

Hydroxypropyl methylcellulose ntshiab yog qhov muag fluffy thiab muaj qhov ceev tsawg, xws li 0.3-0.4g / ml; HPMC adulterated muaj qhov fluidity zoo dua thiab xav tias hnyav dua, uas yog qhov sib txawv ntawm cov khoom tiag tiag hauv qhov tsos. Qhov tsos ntawm qee cov cellulose tshwj xeeb kuj txawv ntawm cov lus qhia dav dav, thiab cov khoom tshwj xeeb raug tshuaj xyuas kom meej.

cov kua dej

Cov kua dej HPMC ntshiab yog qhov tseeb, lub teeb ci ntsa iab, tus nqi khaws dej ≥ 90%; cov kua dej HPMC uas tau muab tso rau hauv dej yog turbid, thiab tus nqi khaws dej nyuaj rau ncav cuag 70%

Txawm hais tias qhov dawb tsis tuaj yeem txiav txim siab seb puas yogHPMCyooj yim siv, thiab yog tias ntxiv cov tshuaj dawb thaum lub sijhawm tsim khoom, nws yuav cuam tshuam rau nws qhov zoo. Txawm li cas los xij, feem ntau ntawm cov khoom zoo muaj qhov dawb zoo.
