Hydroxypropyl Methylcellulose

HydroxypropylMethylcellulose (HPMC) kapena hypromellosendi chochokera kus ya Methyl cellulose ma ether. Ndiulusi woyera kapena wosaoneka bwino kapena wopyapyalaether ya celluloseufa. Pakadali pano ndi cellulose ma ether ndi magwiridwe antchito abwino kwambiri padziko lonse lapansi, kuphatikiza kukhuthala, kuyimitsa, kufalitsa, kusakaniza ndi kukhazikika. Hydroxypropyl methyl cellulose (HPMC) Sili ndi poizoni, ndi losavuta kugwiritsa ntchito, ndipo limasungunuka mosavuta m'madzi. Ndi polyanion mu yankho lamadzi ndipo lili ndi mawonekedwe apadera. Kagwiridwe kake ka ntchito ndi monga pansipa:

Kufotokozera Kwathupi ndi Mankhwala

HPMC yomanga kalasi

HPMC yotsukira madzi

HPMC ya ceramic grade

HPMC yokongola kwambiri

Mankhwala a HPMC

PVC kalasi HPMC

HPMC ya mtundu wa chakudya

Mawonekedwe:

1. Kusungunuka: Sichisungunuka mu ethanol, ether ndi acetone yeniyeni, ndipo chimasungunuka kukhala yankho loyera kapena lopanda madzi ambiri m'madzi ozizira. Chingathe kusungunuka mu zosungunulira zina zachilengedwe, ndipo chingasungunukenso mu zosungunulira zosakaniza za madzi ndi zachilengedwe.

2. Kukana mchere: Sichimasinthasintha m'madzi amchere pamene pali mchere wachitsulo kapena ma electrolyte achilengedwe.

3. Ntchito pamwamba: ingagwiritsidwe ntchito ngati choteteza cha colloid, emulsifier ndi dispersant.

4. Kukhazikika kwa PH: Mtengo wa PH ndi wokhazikika pakati pa 3.0 ndi 11.0. Kukhuthala kwa madzi amadzi sikukhudzidwa kwambiri ndi asidi kapena alkali.

Buku Lotsogolera la HPMCMalangizo:

1. Njira yothira madzi otentha: Onjezani theka la madzi mu chidebecho ndikutenthetsa mpaka madigiri 80. Hydroxypropyl methyl cellulose yoyamba(HPMC) Zitha kufalikira mofanana m'madzi otentha, kenako onjezerani madzi ozizira otsalawo mu slurry ya madzi otentha, ozizira mukasakaniza.

2. Njira yosakanizira ufa: sakanizani hydroxypropyl methyl cellulose(HPMC) ufa ndi zosakaniza zina zambiri za ufa, muufalitse bwino posakaniza mouma, kenako onjezerani madzi kuti musungunuke.

3. Njira yonyowetsera zinthu zachilengedwe: choyamba falitsani kapena nyowetsani hydroxypropyl methyl cellulose (HPMC) ndi chosungunulira chachilengedwe, kenako onjezerani madzi kuti chisungunuke.
