Indlela yokuchithwa kwe-Hydroxypropyl methylcellulose (HPMC):

Uma imikhiqizo ye-hydroxypropyl methylcellulose (HPMC) yengezwa ngokuqondile emanzini, izobumbana bese incibilika, kodwa lokhu kuncibilika kuhamba kancane kakhulu futhi kunzima.Kunezindlela ezintathu zokuhlakaza eziphakanyisiwe ngezansi, futhi abasebenzisi bangakhetha indlela elula kakhulu ngokuya ngokusetshenziswa kwabo:

1. Indlela yamanzi ashisayo: Njengoba i-hydroxypropyl methylcellulose (HPMC) ingancibiliki emanzini ashisayo, isigaba sokuqala se-hydroxypropyl methylcellulose (HPMC) singahlakazwa ngokulinganayo emanzini ashisayo, bese kuthi lapho sesipholisiwe, izindlela ezintathu ezijwayelekile zichazwe ngokuthi kuyalandela:

1).Faka inani elidingekayo lamanzi ashisayo esitsheni bese ushisa kuze kufike ku-70°C.Kancane kancane yengeza i-hydroxypropyl methylcellulose (HPMC) ngaphansi kokunyakaziswa kancane, i-hydroxypropyl methylcellulose (HPMC) iqala ukuntanta phezu kwamanzi, bese kancane kancane yakhe i-slurry, ipholise i-slurry ngaphansi kokunyakaziswa.

2).Shisisa i-1/3 noma 2/3 (inani elidingekayo) lamanzi esitsheni bese usishisa ku-70°C.Ngokwendlela ye-1), hlakaza i-hydroxypropyl methylcellulose (HPMC) ukulungiselela udaka lwamanzi ashisayo;Bese wengeza inani elisele lamanzi abandayo noma amanzi eqhwa esitsheni, bese wengeza amanzi ashisayo e-hydroxypropyl methylcellulose (HPMC) emanzini abandayo, bese ugoqa, bese upholisa ingxube.

3).Faka i-1/3 noma 2/3 yenani elidingekayo lamanzi esitsheni bese usishisa ku-70°C.Ngokwendlela ye-1), hlakaza i-hydroxypropyl methylcellulose (HPMC) ukuze ulungiselele udaka lwamanzi ashisayo;Inani elisele lamanzi abandayo noma e-ice libe selifakwa emanzini ashisayo e-slurry futhi ingxube iyapholiswa ngemva kokugubha.

2. Indlela yokuxuba impushana: izinhlayiya ze-hydroxypropyl methylcellulose (HPMC) kanye nenani elilinganayo noma elikhulu lezinye izithako eziyimpuphu zihlakazwa ngokugcwele ngokuxuba okomile, bese zihlakazwa emanzini, bese i-hydroxypropyl methylcellulose Base cellulose (HPMC) ingancibilika ngaphandle kokuhlanganiswa. .3. Indlela yokumanzisa i-organic solvent: i-pre-disperse noma i-hydroxypropyl methylcellulose emanzi (HPMC) enezinyibilikisi zemvelo ezifana ne-ethanol, i-ethylene glycol noma uwoyela, bese uyincibilikisa emanzini.Ngalesi sikhathi, i-hydroxypropyl methylcellulose (HPMC) ingancibilika kahle.
