Ndeupi musiyano uripo pakati peHPMC E5 uye E15?

HydroxyPropyl methylcellose (HPMC) ndeye semi-synthetic, inert, viscoelastic polymer mune akasiyana maindasitiri kusanganisira mishonga, kuvaka, chikafu, uye zvidyarwa. Iyo inotorwa kubva ku cellulose kuburikidza nemakemikari kugadziridzwa. HPMC inowanikwa mumakiredhi akasiyana neiyo degree rekutsiva Iwo mamakisi anoitwa akasanganiswa nemavara enhamba nenhamba, vakadai saE5 uye E15.

1. Molecular chimiro:
HPMC E5:
HPMC E5 inoreva giredhi reHPMC ine degree rakaderera rekutsiva kwehydroxpropropyl uye mapoka mapoka achienzaniswa neE15.
Dhigirii rakadzika rekutsiva rinoratidza vashoma hydroxyprupyl uye mapoka mapoka pane cellulose unit muPolymer Chain.
HPMC E15:
HPMC E15, kune rumwe rutivi, ine mwero wepamusoro wekutsiva kwehydroxypruppropropropyl uye mapoka madyokisheni achienzaniswa neE5.
Izvi zvinoreva huwandu hukuru hwe hydroxyprupyl uye nzira mapoka pane cellulose unit mumaketeni emapolymer.

2. Viscosity:
HPMC E5:
HPMC E5 kazhinji ine yakaderera viscosity zvichienzaniswa neE15.
Yakadzika viscosity mamakisi seE5 inowanzoshandiswa kana yakaderera yakakora mhedzisiro inodikanwa mukuumbwa.
HPMC E15:
HPMC E15 ine yakakwira viscosity ichienzaniswa neE5.
Yakakwira viscosity mamakisi seE15 inodiwa kana ikasarudzika kana iri nani mvura yekuchengetwa kwemvura inodiwa mukushandisa.

3. Soluby mvura:
HPMC E5:
Vese HPMC E5 uye E15 inhambwe yemvura.
Nekudaro, iyo solubility inogona kusiyana zvishoma zvichienderana nezvimwe zvinhu zvekuumbwa uye mamiriro ekunze.
HPMC E15:
SaE5, HPMC E15 inokanyiwa nyore nyore mumvura.
Iyo inoumba pachena, viscous mhinduro pane kupaza.

4. Zvikumbiro:
HPMC E5:
HPMC E5 inowanzoshandiswa mukushandisa maingi ipo pakaderera viscosity uye mwero wakakora wakabatanidzwa zvinodiwa.
Mienzaniso yezvikumbiro zvinosanganisira:
Mishonga yemishonga yemishonga (sezvikwangwani, disintegraphrucons, kana yakadzorwa-kuburitsa vamiririri).
Zvigadzirwa zvekutarisira pachako (sezvikwangwani mumakiromita, uye zvinyoronyoro, uye shampoos).
Indasitiri yechikafu (seyekufambisa mumiririri kana kuti thickener).
Indasitiri yekuvaka (seyakawedzera muzvikamu zve coment-baster yekuvandudza kushanda uye kudzokorora kwemvura).
HPMC E15:
HPMC E15 inodiwa mune application inoda kukwirisa viscosity uye yakasimba yakakora nzvimbo.
Zvishandiso zveHPMC E15 zvinosanganisira:
Formaceutical formautication (sezvo jelling vamiririri, viscosity modifiers, kana kuti vashandi vekusunungurwa-vakaburitswa).
Zvivakwa zvekuvaka (sedhizimusi kana binder mune tile adhesives, plaster, kana magirazi).
Indasitiri yechikafu (seyemumiriri wakakora mune sosi, puddings, kana zvigadzirwa zvemukaka).
Cosmetic indasitiri (mune zvigadzirwa inoda yakakwira viscosity, yakadai seyebvudzi jege kana kusimbisa mauseses).

5. Kugadzira maitiro:
HPMC E5 uye E15:
Iyo yekugadzira maitiro eiyo HPMC E5 uye E15 inosanganisira iyo itsera iyo cellulose ine propylone oxide uye methyl chloride.
Iyo degree rekutsiva rinodzorwa panguva yeSynthesis kuti uwane zvivakwa zvaunoda.
Mahara akasiyana-siyana akadai sekuita nguva, tembiricha, uye huwandu hwevadzidzi hwakagadziriswa kuburitsa hpmc nehumwe hunhu.

Misiyano huru pakati peHPMC E5 uye E15 inorara mumanyorerwo avo molecular, viscosity, uye application. Nepo mamakisi ese ari manyoro-emvura anodzikisira kubva kuCellulose, HPMC E5 ine degree rakaderera rekutsiva uye viscosity zvichienzaniswa neHPMC E15. Nekuda kweizvozvo, E5 inokodzera kuti zvikumbiro zvinoda kuderera viscosity uye zvine mwero zvakakora zvivakwa, nepo E15 inosarudzwa kuti zvibodzwa zvinoda kukwirisa viscosity uye kwakasimba kwakasimba mhedzisiro. Kunzwisisa misiyano iyi kwakakosha kusarudza giredhi rakakodzera reHPMC yeiyo chaiyo nzira uye maapplication.
