Ndeipi tembiricha yeiyo hydroxyropropyl methylcellose?

Tembiricha yeiyo hydroxyprusypressl methylcellose (HPMC) i parunyanga remaindasitiri akasiyana-siyana, kusanganisira mishonga yemishonga, chikafu, zino, uye kuvaka. HPMC ndeye Synthetic Polymer inotorwa kubva kuCellemose, inoshandiswa zvakanyanya sedhizaini, binder, uye stabilizer zvikumbiro zvakawanda nekuda kwezvinhu zvayo, uye zvisina kujairika, uye mafirimu ekuumba mafirimu.

Kunzwisisa tembiricha yeHPMC kwakakosha nekuti zvinokanganisa viscosity, maitiro ekutenderera, izvo zvinoshandiswa nemhedzisiro yezvigadzirwa zveGel. Nzira dzekutsunga, uye kukosha kwayo kwese maindasitiri akasiyana.

Chii chinonzi Gel tembiricha?
Iyo tembiricha yemapuranga yemapolymer inotaura nezve tembiricha iyo iyo inoumba gel pane hydration kana kupaza mushoma. For hpmc, uku ndiko tembiricha iyo iyo polymer they they Shanduko iyi kubva pane mhinduro yeGel State ndeyekutsoropodza kuita kwayo mukushandiswa kwakasiyana siyana.

Zvinhu zvinokanganisa dengreen tembiricha yeHPMC:
Dare rekutsiva Kazhinji, DS yakakwira inotungamira kudziya kupisa kwegwenzi.

Molecular uremu (MW): Yakakwira molecular uremu HPMC inowanzove nekumusoro-smagetsi ekumira kwegomba nekuda kwekuwedzera keteni.

Kusimbisa uye solvent: Gel tembiricha inokurudzirwa neHPMC yekuvhara uye chimiro cheiyo solvent. Nzvimbo yepamusoro uye mamwe mashonga inogona kudzikisa tembiricha yeGel.

Kuwedzera: Kuwedzera kwemunyu, Acids, kana vamwe polymers vanogona kushandura maitiro eHPMC.

PH: PH inobata ionization yemapoka anoshanda paHPMC, iyo inoshandura maitiro ayo exation maitiro.

Kutsunga kweGel tembiricha:
Nzira dzinoverengeka dzinoshandirwa kuti dzisarudze tembiricha yeHPMC:

Kuona kwekuona: Kuongorora mhinduro pazvinoratidzika shanduko muViscosity kana turbidity sekuchinja kwe tembiricha.

Rheological zviyero: uchishandisa rheometers kuyera shanduko muViscosity kana elastic modulus sebasa rekushisa.

Kusiyanisa kuongorora Calorimetry (DSC): Kuongorora iyo endothermic Peak inoenderana neGel kuumbwa.

Turbidimetry: Kutarisa kuongorora kweSolude uchishandisa maClemission Transmission maitiro.

Kukosha kwese maindasitiri:
Systems: Mune zvinodhaka zvekutakura zvinodhaka

Indasitiri yekudya: HPMC inoshandiswa seanoti, stabilizer, uye gelling mumiririri mune zvigadzirwa zvekudya. Gel tembiricha inokanganisa chimiro, muromo, uye kusimba kwekudya kwekudya.

Cosmetics: Gel tembiricha inokoshesa zvimiro zvechitsidzo zveCosmetic mafomu, zvinokanganisa kuwirirana kwechigadzirwa, kugadzikana, uye hunhu hwekunzwa.

Kuvaka: Muzvivakwa zvekuvaka semutya uye zvinonamatira, HPMC's Gel tembiricha inobata basa, kurongedza nguva, uye yekupedzisira chigadzirwa simba.

Iyo tembiricha yeiyo hydroxyprupypropyl methylcellestulose inotora basa rekupindirana mukuita kwayo kuyambuka maindasitiri akasiyana siyana. Kunzwisisa zvinhu zvinopesvedzera magazini uye kushandisa nzira dzakakodzera kuyerwa kwakakosha kune vanokwana kugadzirisa zvigadzirwa zvekugadzira uye kuve nechokwadi chaunoda. Maindasitiri achiramba achigadzira, kunyengedza kweHPMC tembiricha yeHPMC icharamba iri nzvimbo yekutsvaga inoshanda uye kukudziridzwa, kutyaira mukufambisa kwakasiyana siyana.
