Isiphumo se-selsulose ether (i-HPMC MHC

I-selsulose ether (efana ne-HPMC, i-Hydroxypropyl Methylcelcelcelose) kunye ne-MHEC (i-MHCYL Hydroxyyteetheethy) Badlala indima ebalulekileyo ekuphuculeni amandla e-fes, ukuphucula ukusebenza kokwakhiwa nokudlulisela ixesha lokufakelwa.

1. Iipropathi ezisisiseko ze-HPMC kunye ne-MHEC
I-HPMC yindawo ye-polymer efunyenwe ngokutshintsha kweekhemikhali zeselutase yendalo. Iimolekyuli zayo ziqukethe i-hydroxyPy ye-hydroxypy kunye namaqela e-methyl, ezenza ukuba kube lula ukubenzela amanzi kakuhle, ukuqina kunye nokuzinza. I-MHEC ifana ne-HPMC, kodwa inamaqela e-hydroxyyl kwisakhiwo sayo semolekyuli, ngoko ke ukubenzela amanzi kunye nokuzinza kwentsebenzo ye-MHHC kwahlukile. Zombini zinokubekwa isakhiwo senethiwekhi kudaka kwaye siphucula iimpawu zomzimba zodaka.

2. Indlela yokusebenza ye-Selese Ether e-Ertor
Emva kokongeza i-HPMC okanye i-MHEC elulalweni, i-selsulose i-ether Molekyules yenza inkqubo yecolloidal enamanzi ngokusebenzisana namanzi, amanye amalungu eemichiza kunye namasuntswana eemichiza. Le nkqubo inokuphucula kakhulu iipropathi zodaka.

Isiphumo sokuqaqamba: I-HPMC kunye ne-MHC inokongeza ukungqinelana kodaka, kokwenza kube lula ukusebenza ngexesha lokwakha. Oku kubangelwa lukhuni kuyanceda ukunciphisa ulwelo lwe-qumence, phucula ububi bodaka, kwaye ngaloo ndlela kuphucu amandla amandla odaka.

Ukugcinwa kwamanzi: Isakhiwo seemolekyuli ze-HPMC kunye ne-MHEMC iqulethe amaqela e-hydrophilic, enokufumana isixa esikhulu samanzi kwaye sikhulule kancinci, ngaloo ndlela sikuphephe ixesha elivulekileyo okanye ukugqobhoza umthambo wamanzi.

Ukuphucula ukuSebenza nokuSebenza: UkuSebenza kokwakha: I-Ether Ither Ether inceda ekuphuculeni udaka lodaka, ivumela ukuba isetyenziswe ngokulinganayo kumphezulu wesiseko samandla.

I-3. Isiphumo se-selsulose ether kwi-farr
Ukongezwa kwe-targulose i-ether ukuya kudaka kuvame ukuchaphazela ngakumbi amandla odaka. Ngokukodwa, iziphumo ze-HPMC kunye ne-MHEC kwi-farrdo yokubhaka zibonakaliswa kule miba ilandelayo:

3.1 Impembelelo kumandla okuqala aphezulu
I-HPMC kunye ne-MHC inokuphucula ukusebenza komsebenzi ophakathi kodaka kunye nomhlaba osisiseko. Xa ulwakhiwo lugqityiwe, amandla aphezulu phakathi komhlaba kunye ne-subtate iphuculwe kakhulu kuba i-Ether Ither ingagcina amanzi kwaye inciphise ukwaliwa kwangaphambili kwesamente. Kungenxa yokuba i-quation hydration yokuphendula inokuqhubeka kakuhle, ekhuthaza ukuqiniswa kokukhanya kodaka.

3.2 Impembelelo kumandla exesha elide lokuhambisa
Njengoko ixesha lihamba, icandelo lesamente lesikhonkwane lodaka liyaqhubeka inkqubo eqhubekayo yokwenziwa kwemithambo, kwaye amandla odaka aya kuqhubeka enyuka. Umsebenzi wokugcinwa kwamanzi kwe-Ilete Ether isebenza kwindima ephambili kule nkqubo, ukunqanda ukubohlwaya ngokukhawuleza kwamanzi e-fanshintsho, ngaloo ndlela kuncitshiswa amandla okubangelwa ngamanzi angonelanga.

3.3 Ukuphucula ukunganyangeki kodaka
I-HPMC kunye ne-MHEC inokuphucula ukwanda kokuchasana nodaka. Indlela yayo yesenzo ikakhulu yokuphucula uzinzo lwangaphakathi lodaka kwaye icothe kancinci imigangatho yokuphuma kwamanzi kumphezulu wodaka, ngaloo ndlela kuncitshiswe ingxaki yokuphuma kwamanzi. Ukongeza, isakhiwo se-colloidal eyenziwe nge-ether iseti eluthuthwini sinokuphucula ubunzima obupheleleyo bodaka, busenza kube lula ukuba banciphise amandla angaphandle.

3.4 Iziphumo kumandla okuphuculwa kodaka
Izifundo zibonakalisile ukuba ukongeza isixa esifanelekileyo se-HPMC okanye i-MHEC inokuphucula amandla obukho bodaka ngaphandle kokukhulisa ubunzima bodaka. Ngokubanzi, i-dosage efanelekileyo ye-ether sether yi-0.5% -1.5%. Ukongeza kakhulu kunokubangela udaka ukuba lube nolwelo olugqithisileyo, oluchaphazela iipropathi zayo. Ke ngoko, isixa esifanelekileyo se-itelulose ether ye-Ether yongezwa ekwandiseni amandla odaka.

4. Thelekisa iindidi ezahlukeneyo zeselpulose
Nangona i-HPMC kunye ne-MHC ziyafana ngendlela yabo yesenzo, iziphumo zabo kumandla aphezulu kodaka zahlukile kwizicelo ezizayo. I-MHEC ingakumbi i-hydrophilic kune-HPMC, kunjalo kwindawo enomswana, i-MHC inokuba nempembelelo ebaluleke kakhulu ekuphuculeni amandla aphezulu. I-HPMC, kwelinye icala, izinzile ngakumbi phantsi kwamaqondo obushushu aqhelekileyo kunye neemeko zokufuma, kwaye zilungele amalungiselelo odaka.

I-SelesUlose ees (i-HPMC kunye ne-MHC) isetyenziswa i-conoditives esetyenziswayo kwizifa, eziphucula amandla amakhulu okuzala, ukugcinwa kwamanzi, kunye nokuphucula ulwalamano. Ukusetyenziswa okufanelekileyo kwe-Ether I-Selerse-I-Ether ayinakuphela nje ukunamathela kuphela phakathi kodaka phakathi kodaka kunye nokuthathwa komhlaba, kodwa kukuphucula ukunganyangeki kodaka kunye nokuqina kobomi, kwaye kwandise ubomi benkonzo. Iindidi ezahlukeneyo ze-Selese Ether Ine-Etesese Inezinto ezisetyenzisiweyo ezahlukeneyo, kwaye ukhetha imveliso elungileyo kunye nedosi kubalulekile ekuphuculeni indlela yokusebenza kodaka.
