Na u tseba hydroxypropyl methylcellulose?

Hydroxypropyl methylcellulose e sebelisoa haholo indastering ea kaho. Kajeno, ke tla hlahisa mokhoa oa ho qhibiliha oa hydroxypropyl methylcellulose le mokhoa oa ho ahlola boleng ba hydroxypropyl methylcellulose.

Mokhoa oa ho qhaqha hydroxypropyl methylcellulose:

Mefuta eohle e ka ekeletsoa boitsebisong ka ho kopanya ho omileng;

Ha e hloka ho ekeletsoa ka ho toba mocheso o tloaelehileng oa metsi a nang le metsi a futhumetseng, ho molemo ho sebelisa mofuta oa ho hasana ha metsi a batang, 'me o ka teteana ka hare ho metsotso e 10-90 ka mor'a ho eketsa;

Ka mor'a ho hlohlelletsa le ho qhalakanya ka metsi a chesang bakeng sa mofuta o tloaelehileng, eketsa metsi a batang 'me u hlohlelletse ho e qhaqha;

Haeba ho na le agglomeration le ho roala nakong ea ho qhibiliha, ho bakoa ke ho sa lekaneng ho susumetsa kapa ho eketsa ka ho toba metsi a batang ho litlaleho tse tloaelehileng. Ka nako ena, e lokela ho tsosoa ka potlako;

Haeba li-bubble li hlahisoa nakong ea ho qhibiliha, li ka tloheloa hore li eme lihora tse 2-12 (tse khethiloeng ho latela ho lumellana ha tharollo) kapa li tlosoe ka ho tlosoa, khatello ea maikutlo, joalo-joalo, 'me palo e loketseng ea defoamer e ka boela ea ekeletsoa.

Mokhoa oa ho ahlola boleng ba hydroxypropyl methylcellulose habonolo le ka mokhoa o hlakileng

Bosoeu: Ho ea ka bosoeu, ho ke ke ha khoneha ho fumana hore na HPMC e ka sebelisoa ka tloaelo, 'me haeba li-whitening agents li kenngoa ts'ebetsong ea tlhahiso, li tla ama boleng ba tsona. Leha ho le joalo, lihlahisoa tse nang le bosoeu bo botle hangata li ntle.

Bokhabane: HPMC ka kakaretso ke 80 mesh, 100 mesh, 120 mesh, e ntle ho feta ho feta.

Transmittance: kenya HPMC ka metsing ho etsa colloid e bonaletsang, 'me u shebe phetiso ea eona. Ha phetisetso e kholoanyane, ke lintho tse fokolang tse sa qhibiliheng metsing. Ka kakaretso, phetiso e betere ho li-reactor tse otlolohileng le tse tšekaletseng. E mpe le ho feta ho reactor e otlolohileng, empa e ke ke ea hlalosa hore boleng ba sehlahisoa se hlahisoang ke mochine o otlolohileng o molemo ho feta oa mochine o otlolohileng.

Matla a khoheli a khethehileng: Ka kakaretso, ka lebaka la litaba tse phahameng tsa hydroxypropyl, phello ea ho boloka metsi e ntle.
