Misiyano mune yemuviri uye makemikari zvivakwa pakati peHPMC uye HEMC

HydroxyPropyl methylcellose (HPMC) uye hydroxyTHETL methylcellose (Hemc) is cellyloselose (Hemc) ende cellulose inoshandiswa zvakanyanya mumagirendi akasiyana siyana nekuda kwezvivakwa zvavo zvemuviri uye zvemakemikari. Kunyangwe zvivakwa zvavo zvemakemikari zvakafanana, kune misiyano yakakosha mune yavo zvivakwa izvo zvinoita kuti vakwanise kuve vakakodzera kuti vashandiswe zvakasiyana.

1.comemical chimiro:

Zvese HPMC uye HEMC inotorwa kubva kuCellulose, iyo yakasikwa Polymer. Musiyano mukuru unorara mune zvisizvo zvakabatanidzwa kune iyo cellulose backbone. MuHPMC, subsituer inosanganisira methyl uye hydroxypruppropyl, ichiri muHemc, siderstues inosanganisira methyl uye hydroxyethyl. Izvi zvinotsiva zvinogona kukanganisa zvivakwa zvakazara zve cellulose ana vana.

2. Solubility:

Musiyano wakakosha pakati peHPMC uye hemc ndiyo maitiro avo ekugadzirisa. HPMC inoratidzira iri nani solubility mumvura inotonhora ichienzaniswa neHEMC. Ichi chivakwa chakanyanya kuoma zvekushandisa zvinoda kukurumidza kuparadzaniswa kana kuvaparadzira polymers, senge mune maindasitiri emishonga uye ekuvaka emaindasitiki.

3. Kuchengeta mvura:

HPMC inowanzove ine iri nani mvura yekuchengetwa kwekuwedzera kupfuura hemc. Ichi chivakwa chakanyanya kutsoropodzwa mune zvekushandisa senge masisitimu ezvemumumumende, uko kuchengetwa kwemvura kunobatsira kudzora maitiro e hydration uye kuvandudza basa rekushanda.

4.

Kupisa tembiricha ndiyo tembiricha iyo mhinduro kana kupararira inoshandura ive gel. Hemc kazhinji mafomu jekeri pakudziya kudzedzereka kupfuura hpmc. Ichi chivakwa chinogona kunge chiri chakanaka chinobatsira senge zvigadzirwa zvekudya, uko kupisa kwepazasi kunogona kudikanwa kune yakatarwa mamiriro ekugadzirisa.

5.Rhelogical Properties:

Zvese HPMC uye hemc inopa kune iyo rateological maitiro emhinduro kana kuparadzaniswa. Nekudaro, mhedzisiro yavo pane viscosity uye shear yekufungidzira maitiro anogona kusiyana. Hemc anowanzopa inopa yakakwira viscosities pane yakaderera kutarisisa, ichiita kuti ive yakakodzera kune zvimwe zvekushandisa izvo zvinoda mhinduro dzakasarudzika.

6. Film Ford:

HPMC uye hemc inogona kuumba mafirimu akaonda kana akaiswa munzvimbo. Zvichienderana neCellulose ether inoshandiswa, mafirimu anoratidza zvivakwa zvakasiyana. HPMC mafirimu anowanzo shanduka zvakanyanya, nepo hemc films iri yakawanda brittle. Ichi chivakwa chinokanganisa kushandiswa kwavo mumakonzo, zvinonamatira uye zvimwe zvinoshandiswa mafirimu ekugadzira mafirimu.

7. Kuenderana nedzimwe makomendi:

Iyo sarudzo pakati peHPMC uye HEMC zvakare zvinoenderana nekuenderana kwavo nedzimwe makomendi. Semuenzaniso, HPMC inowanzo sarudza mune mishonga yemishonga nekuda kwekuwirirana kwayo neyakajairwa zvinoshandiswa, nepo hemc inogona kusarudzwa kune chaiyo yekushandisa zvichienderana nehunhu hwayo hunoenderana.

8. Kugadzikana kweFormal:

Vese vese cellulose eter vanoratidzira zvakanaka zvekugadzikana, asi tembiricha idzo dzinosvibisa dzinogona kusiyana. HPMC inowanzo kuve yakakwira yekukwira kugadzikana kuenzaniswa neHEMC. Iyi ficha yakakosha pakushandisa uko kuratidzwa kune yakanyanya kupisa tembiricha.

Kunyangwe HPMC uye HEMC Mugovana Cellulose Backbone, yavo chaiyo yemakemikari Substitution mhedzisiro yemuviri uye yemakemikari. Kunzwisisa misiyano iyi ndeyekutsoropodza kusarudza iyo yakakodzera cellulose ether yekunyorwa kwayo, ichisvika pakubata kwayo kuita uye kushanda. Sarudzo pakati peHPMC uye Hemc zvinoenderana nezvinodiwa zvekushandisa, kubva kune mishonga yemishonga uye zvigadzirwa zvekuvaka kune zvekudya nezvikafu.
