I-Hydroxypropyllylylyl methyl cellulose kanye ne-carboxymethyl cellulose sodium ingahlanganiswa

I-Hydroxypropyl methyl cellulose (HPMC) kanye ne-carboxymethyl cellulose sodium (CMC) Ingabe izici ezimbili ezisetshenziswa kabanzi ze-cellulose decivatives ezimbonini ezahlukahlukene ngenxa yezakhiwo zazo ezihlukile kanye nokusebenza. Ngenkathi bobabili bangama-polymers asuselwa ku-cellulose, ahlukile ngesakhiwo sabo samakhemikhali nasezakhiweni, ezibenza balungele izinhlelo zokusebenza ezihlukile. Kodwa-ke, kwezinye izikhathi, zingahlanganiswa ukuze kufinyelelwe izici ezithile zokusebenza noma ukuthuthukisa izakhiwo ezithile zomkhiqizo wokugcina.

I-Hydroxypropyl Methyl Cellulose (HPMC), eyaziwa nangokuthi i-Hypromellose, iyi-ether engeyona eye-cellulose ethathwe ku-polymer cellulose yemvelo. Ihlelwe ngokusabela kwe-Alkali Cellulose nge-propelene oxide ne-methyl chloride. I-HPMC isetshenziswa kabanzi emithi yezemithi, izinto zokwakha, imikhiqizo yokudla, kanye nezimonyo, kanye nezimonyo ngenxa yezakhiwo zayo ezinhle kakhulu zefilimu, ukuqina, okubophayo kanye nokugcinwa kwamanzi. I-HPMC iyatholakala kumabanga ahlukahlukene anamazinga ahlukile we-viscosity, avumela ukusetshenziswa kwawo ezinhlobonhlobo zezicelo.

Ngakolunye uhlangothi, i-carboxymethylllose sodium (CMC) i-anionic cellulose etholwayo etholwe ukusabela kwe-cellulose nge-sodium hydroxide ne-chlororoacetic acid. I-CMC yaziwa ngamandla ayo okugcina amanzi aphezulu, amandla okuqina, izakhiwo ezakha amafilimu, nokuqina kwezimo ezahlukahlukene ze-PH. Ithola izinhlelo zokusebenza emikhiqizweni yokudla, amakhambi emithi, izimonyo, izindwangu, kanye nokukhiqiza amaphepha ngenxa yokusebenza okuhlukahlukene kanye nokuqina kwayo.

Ngenkathi i-HPMC ne-CMC yabelana ngezakhiwo ezijwayelekile ezifana ne-soubity yamanzi kanye nekhono elenza ifilimu, zibonisa nezimpawu ezihlukile ezibenza zibe zilungele izinhlelo ezithile. Isibonelo, i-HPMC ilindelwe ekwakhiweni kwemithi njengamathebulethi kanye nama-capsule ngenxa yezindawo zayo ezilawulwa okulawulwayo kanye nokuhambisana nezithako ezisebenzayo zemithi. Ngakolunye uhlangothi, i-CMC ivame ukusetshenziswa emikhiqizweni yokudla efana nososo, ukugqoka, kanye nezimpahla ezibhakiwe njenge-ejenti yokuqina kanye ne-stabilizer.

Naphezu kokungafani kwabo, i-HPMC ne-CMC ingahlanganiswa ndawonye ekwakhiweni okuthile ukuze kufinyelelwe imiphumela yokushintshana noma ukuthuthukisa izakhiwo ezithile. Ukuhambisana kwe-HPMC ne-CMC kuncike ezicini eziningana ezifana nesakhiwo sazo samakhemikhali, isisindo samangqamuzana, izinga lokufaka esikhundleni, kanye nezici ezifiselekayo zomkhiqizo wokugcina. Lapho kuxutshaniswe ndawonye, ​​i-HPMC ne-CMC ingakhombisa ukuqina okuthuthukile, okubophayo kanye nezakhiwo ezenziwe ngefilimu uma kuqhathaniswa nokusebenzisa i-polymer iyodwa.

Ukusetshenziswa okukodwa okujwayelekile kwe-HPMC ne-CMC kusekwakhekeni kwamasistimu wokulethwa kwezidakamizwa asuselwa kwi-hydrogel. Ama-Hydrogels anezinhlaka zenethiwekhi ezinezinhlangothi ezintathu ezikwazi ukumunca nokugcina amanzi amakhulu, abenze balungele izinhlelo zokusebenza zokukhishwa kwezidakamizwa ezilawulwayo. Ngokuhlanganisa i-HPMC ne-CMC ngezilinganiso ezifanele, abacwaningi bangakwazi ukuvumelanisa izakhiwo zama-hydrogels njengokuziphatha kokuvuvukala, amandla okukhishwa kwezidakamizwa, kanye nemithi yokukhululwa kwezidakamizwa ukufeza izidingo ezithile.

Okunye ukusetshenziswa kwe-HPMC ne-CMC kusekulungiseleleni upende osuselwa emanzini kanye nezingubo zokugqoka. I-HPMC ne-CMC zivame ukusetshenziswa njengabakhulu kanye nama-rheology modifiers kumapende asuselwa emanzini ukuthuthukisa izakhiwo zohlelo lokusebenza, njengokulimala, nokumelana nokuvimbela okuhlwabusayo. Ngokushintsha isilinganiso se-HPMC kuya ku-CMC, amakhemikhali angafinyelela i-viscosity efiselekayo yokuziphatha kanye nokuziphatha okugelezayo kopende ngenkathi kugcinwa ukuqina nokusebenza kwayo ngokuhamba kwesikhathi.

Ngaphezu kwemithi kanye nezimbozo, izixhobo ze-HPMC ne-CMC nazo zisetshenziswa embonini yokudla ukuze kuthuthukiswe ukuthungwa, ukuqina, kanye nomlomo wemikhiqizo ehlukahlukene yokudla. Isibonelo, i-HPMC ne-CMC zivame ukungezwa kwimikhiqizo yobisi efana ne-yogurt ne-ayisikhilimu njengezitebhisi ukuvikela ukuhlukaniswa kwesigaba futhi kuthuthukise ukuhlukaniswa kwesigaba futhi kuthuthukise ukuhlukaniswa kwesigaba futhi kuthuthukise ukuhlukaniswa kwesigaba futhi kuthuthukise ukuhlukaniswa kwesigaba futhi kuthuthukise ukuhlukaniswa kwesigaba futhi kuthuthukise ukuhlukaniswa kwesigaba futhi kuthuthukise ukuhlukaniswa kwesigaba futhi kuthuthukise ukuhlukaniswa kwesigaba. Ezitolo ezibhakiwe, i-HPMC ne-CMC zingasetshenziswa njengenhlama conditioners ukuthuthukisa izakhiwo zenhlama yokuphatha bese ukhulisa impilo yeshelufu.

Ngenkathi i-hydroxypropylllylyllllulose (HPMC) kanye ne-carboxymethylllose sodium (CMC) ama-cellulose sodium (CMC) ama-cellulose decivativeves ahlukene ama-cellulose decivativeves anezakhiwo ezihlukile nezinhlelo zokusebenza, zingahlanganiswa ndawonye ekwakhiweni okuthile ukuze kufinyelelwe ama-synermistic noma ukuthuthukisa izakhiwo ezithile. Ukuhambisana kwe-HPMC ne-CMC kuncike ezicini ezahlukahlukene ezifana nesakhiwo sazo samakhemikhali, isisindo se-molecular, kanye nezici ezifiselekayo zomkhiqizo wokugcina. Ngokukhetha ngokucophelela isilinganiso kanye nenhlanganisela ye-HPMC ne-CMC, amakhemikhali angavumelanisa izakhiwo zokwakhiwa kwawo ukuze ahlangabezane nezidingo ezithile emikhakheni, embonini, imikhiqizo yokudla, neminye imikhiqizo.
