Ndeupi musiyano uripo pakati peCMC (Carboxymethylcellose) uye Starch Ether?

1. Kuumbwa uye kuumbwa:

CMC (CarboxyMethylcellose):

CMC ndeyekubva kune cellulose, polymer yakasikwa inowanikwa mumadziro emusero.
Ma Cellulose Molecules arikugadzirisa mamiriro emakemikari anonzi CarboxyMeymeymelmelation, mune iyo carboxymethyl mapoka (-ch2-cooh) inounzwa muCellulose Backbone.
Dhigirii rekutsiva

starch:

Starch ndeye carbohydrate inoumbwa neyakagadziriswa magirazi akabatana pamwe chete ne α -,4-glycosic zvisungo.
Iyo polysaccharide iyo ndiyo yekutanga simba rekuchengetedza mamorekuru muzvirimwa.
Starch inogadzirwa nezvinhu zviviri zvikuru: Amylose (maketeni akatwasuka eGlucose zvikamu) uye amyLopewsin (matavi ebhatani).

2. Kunobva:

Sodium carboxymethyl cellose:

CMC inowanzobva kubva ku cellulose-yakapfuma chirimwa masango akadai sehuni dzemapururu, machira, kana zvimwe zvidyarwa zvidiki.
Iyo carboxymethylation nzira inoshandura cellulose muCollose muzvinyorwa zvemvura zvine mwero uye zvimwe zviitiko zvakasiyana.

starch:

Starch inowanikwa mune yakakura yakawanda mune dzakasiyana-siyana zvidyarwa, kusanganisira zviyo (semuenzaniso, chibage, gorosi, mupunga (semuenzaniso, mbatatisi, cassava).
Iyo yekubvisa maitiro inosanganisira kuputsa madziro emusero kusunungura marara ehondo.

3. Solubility:

Sodium carboxymethyl cellose:

CMC ine mvura yakawanda-nyoro nekuda kwekutanga kweCarboxymethyl mapoka, ayo anopa hydrophiliku kune molecule.
Iyo inoumba yakajeka, mazwi ekuvhara mumvura uye akakodzera kune akasiyana-siyana ekushandisa mumaindasitiri akadai sekudya, mishonga uye cosmetics.

starch:

Starch kazhinji inoshaya mumvura inotonhora.
Nekudaro, kupinza starch mumvura kunoita kuti ifunge uye pakupedzisira gungatidziro, kuumba kumiswa kwechikara.

4.Rhelogical Properties:

Sodium carboxymethyl cellose:

CMC inoratidza pseudoplastic maitiro, zvichireva kuti viscosity yayo inoderera nekushambadzira kushushikana.
Ichi chivakwa chakakosha mune zvekushandisa apo kudzora kwe viscossity kuri kutsoropodza, sekusikwa kwemapendi, zvinonamatira uye zvigadzirwa zvekudya.

starch:

Starch-based Systems inogona kugadzira gelatinze, kugadzira gels ine akasiyana zvivakwa zvechiratidzo.
Starch Gels yakakosha muindasitiri yechikafu yekukora uye kugadzira maficha.

5.Inindustrial application:

Sodium carboxymethyl cellose:

Inonyatso kushandiswa muindasitiri yechikafu seanorira, stabilizer uye herocttant.
Izvo zvinowanzoshandiswa mumishonga yemishonga nekuda kwekusunga kwayo uye kusataurisa zvinhu mukugadzira piritsi.
Inowanikwa mune dzakasiyana siyana dzekuchengetedza zvigadzirwa senge mazino uye echiso mafungiro.

starch:

Iyo huru ingori muindasitiri yechikafu, ine kutema, gelly uye kurongedza mhedzisiro.
Inoshandiswa mukugadzirwa kwemapurasitiki ebia
Kuitira sizzes uye kuunganidza muindasitiri yepepa.

6. Biodegradability:

Sodium carboxymethyl cellose:

CMC iri biodegradable uye saka ine zvivakwa zvemamiriro ekunze.
Kushandiswa kwayo mumaindasitiri akasiyana siyana kunoenderana nekuwedzera kudiwa kwekusimudzira uye zvakatipoteredza zvinoshamisa.

starch:

Starch iri zvakare biohandura, ichiita sarudzo yakakodzera yezviripo zvemamiriro ekunze.
Iyo biodergradability yemidziyo-yakavakirwa zvinhu inobatsira kuderedza mamiriro ekunze.

7. Firimu-fomu rekugadzira:

Sodium carboxymethyl cellose:

CMC inogona kuumba mafirimu ane yakanaka mechantices simba uye kushanduka.
Ichi chivakwa chinoshandiswa mukugadzirwa kwemafirimu ezvidhinha uye zvekudya zvekudya.

starch:

Iyo firimu ye starch inoumbwa kuburikidza neiyo gelatination maitiro.
Iyi mafirimu anowana application mune kurongedza, apo zvinhu zveBiodebable zvinosarudzwa.

8. Kubata:

Sodium carboxymethyl cellose:

CMC Solutions inoratidzira imwe mwero weConstivity nekuda kwekuvapo kwemapoka emaraki emaraki.
Ichi chivakwa chinobiridzirwa mune zvimwe zvinoshandiswa, senge indasitiri yemagetsi.

starch:

Starch haina magetsi akakosha maitiro.

9. Mhedziso:

CMC uye starch inosiyana nechimiro, mavambo, zvivakwa uye zvinoshandiswa. CMC inotorwa kubva ku cellulose, ine mhou-yemvura, ine maitiro epsudoplastic, uye inoshandiswa zvakanyanya mune chikafu, mishonga yemishonga, uye maindasitiri ezvinyorwa. Starch iPolysaccharide iyo isingaoneki mumvura inotonhora asi gels kana ichipisa, ichiita kuti ive yakakosha mune chikafu, mapepa uye maindasitiri ekutakura. Ose maviri CMC uye starch zvinobatsira kukudziridza kwekusimudzira uye biodegradable zvinhu, zvinoenderana nekusimbisa kwepasirese pamamiriro ekunze ekushamwaridzana. Kunzwisisa misiyano iyi kunogona kukubatsira kuti uite sarudzo dzakaziviswa pakusarudza zvinyorwa zvakaringana kune chaiyo maindasitiri application.
