Ungayifumana njani i-hpmc?

I-HILMS ye-HPMC (i-HydroxyPOpyl Methylcelceltulose) ihlala ihlengahlengisa uxinzelelo lwayo ukuze ilungele iimfuno ezahlukeneyo zesicelo. I-HPMC yi-polymer ye-polymer ye-prolymer esetyenziswa ngokubanzi kwi-PARMEMACECAL, ukwakhiwa, ukutya kunye nemizi-mveliso yenkcitho.

(1) Ukulungiselela
Khetha eyahlukeneyo ye-HPMC:

I-HPMC inee-viscofisties ezahlukeneyo kunye nezigaba. Ukukhetha iintlobo ezifanelekileyo kunokuqinisekisa ukuba isisombululo esinxilisayo sidibana neemfuno zesicelo.
Lungiselela izixhobo kunye nezixhobo:

I-HPMC POMDER
Amanzi azosiweyo okanye amanzi asezantsi
I-magnetic skirrer okanye i-stirrer
Izixhobo zokulinganisa njengokulinganisa iisilinda kunye neekomityi zokulinganisa
Izitya ezifanelekileyo, ezinjengeebhotile zeglasi okanye iibhotile zeplastiki.

(2) Amanyathelo e-dilution
Ukuvavanya i-HPMC POMDER:

Ngokutsho koxinzelelo ukudilizwa, ngokuchaneka ngokuchanekileyo isixa esifunekayo somgubo we-HPMC. Ngokwesiqhelo, iyunithi yoxinzelelo yipesenti yepesenti (W / W%), enje nge-1%, 2%, njl njl.
Yongeza amanzi:

Galela inani elifanelekileyo lamanzi anemikhono okanye ekhutshiwe kwisitya. Inani lamanzi kufuneka ligqitywe ngokweemfuno zoxinzelelo zesisombululo sokugqibela.
Ukongeza i-HPMC POMDER:

Yongeza i-HPMC ye-HPMC ngokulinganayo emanzini.

Ukuvuselela kunye nokunyibilika:

Sebenzisa i-magnetic shrimrer okanye i-stirfer ivuselela isisombululo. Ukuvuselela kunokunceda i-HPMC Polder inyibilike ngokukhawuleza nangokulinganayo. Isantya kunye nexesha elifanelekileyo kufuneka zilungiswe ngokohlobo kunye ne-HPMC. Ngokubanzi, ixesha elicetyiswayo liyimizuzu engama-30 ukuya kwiiyure ezininzi.

Ukuma kunye nokudinwa:

Emva kokuvuselela, vumela isisombululo silinde ixesha, siqhele iyure enye ukuya kwiiyure ezingama-24 ukuya kwiiyure ezingama-24. Oku kuvumela amaqamza kwisisombululo sokunyuka kwaye anyamalale, aqinisekisa ukufana kwesisombululo.

(3) Amanyathelo okhuseleko

Isantya kunye nexesha:

Isantya kunye nexesha lokutshabalalisa le-HPMC lokuphelisa i-HPMC lichaphazelekile kukufakwa kwalo kunye nobushushu bamanzi. Ngokubanzi, i-viscofity ephezulu ye-HPMC ifuna ixesha elide elitshatileyo.

Iqondo lokushisa lamanzi:

Sebenzisa amanzi afudumeleyo (njenge-40 ° C) kunokukhawulezisa ukutshitshiswa kwe-HPMC, kodwa kulumkele ukuba ungasebenzisi iqondo lobushushu kakhulu ukuthintela ichaphazela ubume be-HPMC.

Ukuthintela ukwahlula-hlula:

Xa uyongeza i-HPMC POMDER, zama ukunqanda ukwahluka. Ungawuqala ukudibanisa umgubo we-HPMC ngenani elincinci lamanzi kwisilayidi, kwaye emva koko ngokuthe ngcembe wongeze emanzini aseleyo ukunciphisa ukwahlukana.
Ukugcinwa:

Isisombululo se-HPMC esikhutshiweyo kufuneka sigcinwe kwisitya esicocekileyo, esitywiniweyo sokuphepha ukufuma okanye ungcoliseko. Iimeko zokugcina kufuneka zilungiswe ngokweemfuno zokusetyenziswa kunye neemeko zendalo kwi-HPMC.
Ukhuseleko:

Ngexesha lokusebenza, izixhobo zokhuselo ezifanelekileyo zobuqu ezinje ngeegloves kunye neemaski kufuneka zinxitywe ukunxibelelana ngqo nomgubo we-HPMC kunye nesisombululo esihlanganisiweyo.

Ngale manyathelo angentla, unokukwenza i-HPMC njengoko kufuneka ukuqinisekisa ukusebenza nokuzinza kwayo kwizicelo ezahlukeneyo. Isicelo ngasinye seso sicelo sinokuba neemfuno ezahlukeneyo, ngoko kubaluleke kakhulu ukuqonda kwaye sithobele imigangatho ethile yokusebenza kunye neemfuno.
