Chii chinonzi Starch Ether?

Starch ether imhando yestarch yakagadziriswa, iyo inotorwa kubva mumiti. Kugadziriswa uku kunosanganisira maitiro emakemikari anochinja chimiro chestarch, zvichikonzera chigadzirwa chine hunhu hwakavandudzwa kana hwakagadziriswa. Starch ethers dzinoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana nekuda kwehunhu hwadzo hwakasiyana. Mamwe marudzi akajairika estarch ethers anosanganisira hydroxyethyl starch (HES), hydroxypropyl starch (HPS), uye carboxymethyl starch (CMS). Heano mativi akakosha estarch ethers:

1. Kugadziriswa kweMakemikoro:

• Hydroxyethyl Starch (HES): MuHES, mapoka ehydroxyethyl anounzwa kumorekuru yestarch. Kugadziriswa uku kunowedzera kunyungudika kwayo mumvura uye kunoita kuti ikodzere kushandiswa mumishonga, sekuwedzera plasma volume, uye mune zvimwe zvinoshandiswa.
• Hydroxypropyl Starch (HPS): HPS inogadzirwa nekuunza mapoka ehydroxypropyl muchimiro chestarch. Kugadziriswa uku kunovandudza hunhu hwakadai sekunyungudika kwemvura uye kugona kugadzira firimu, zvichiita kuti ishande mumaindasitiri akadai sezvekudya, machira, uye kuvaka.
• Carboxymethyl Starch (CMS): CMS inogadzirwa nekuunza mapoka ecarboxymethyl kumamorekuru estarch. Kugadziriswa uku kunoita kuti pave nekuvandudzwa kwekuchengetedzwa kwemvura, kukora, uye kugadzikana, zvichiita kuti ive yakakosha mukushandiswa senge zvinonamira, machira, uye mishonga.

2. Kunyungudika kwemvura:

• Mastarch ethers anowanzo ratidza kunyungudika kwemvura kwakawedzera kana tichienzanisa nestarch yemuno. Kunyungudika uku kwakawedzerwa kunobatsira mukugadzira mishonga apo mvura inoda kunyungudika nekukurumidza kana kupararira mumvura.

3. Hunhu hwekusimba uye kukora:

• Mastarch ether anoshanda sezvinhu zvinosimbisa ganda mumhando dzakasiyana-siyana. Anobatsira kuwedzera kusimba kweganda, izvo zvinokosha mukushandiswa kwakadai sekunama, kuputira, uye zvigadzirwa zvekudya.

4. Kugona Kugadzira Mafirimu:

• Mamwe ma starch ethers, kunyanya hydroxypropyl starch, ane hunhu hwekugadzira firimu. Izvi zvinoita kuti akwanise kushandiswa kana paine firimu rakatetepa uye rinochinjika, senge mumaindasitiri ezvekudya nemishonga.

5. Hunhu Hwekusimbisa uye Kubatanidza:

• Mastarch ether anowanzo shandiswa sezvinodzivirira uye zvinosunga mumhando dzakasiyana-siyana. Anobatsira kuvandudza kugadzikana kwe emulsions uye anobatsira mukubatana kwezvigadzirwa zvakaita semapiritsi emishonga.

6. Zvishandiso zveNamira:

• Mastarch ether anoshandiswa muzvinamira, muindasitiri yezvikafu (semuenzaniso, muzvinamira zvechigum arabic) uye muzvinamira zvisiri zvekudya (semuenzaniso, mumapepa nepakurongedza).

7. Saizi yeMachira:

• Muindasitiri yemachira, starch ethers inoshandiswa mukugadzira saizi kuti shinda dzive dzakasimba uye dzakapfava panguva yekuruka.

8. Mashandisirwo Emishonga:

• Mamwe ma starch ether anoshandiswa mumishonga. Semuenzaniso, hydroxyethyl starch inoshandiswa se plasma volume expander.

9. Kuvaka uye Zvishandiso zveKuvaka:

• Mastarch ether, kunyanya hydroxypropyl starch uye carboxymethyl starch, anoshandiswa muindasitiri yekuvaka, kunyanya mukugadzira dry mix mortar formulations. Anobatsira pakuvandudza kunamira, kushanda zvakanaka, uye kuchengetedza mvura.

10. Indasitiri yezvekudya:

11. Kuora kwechinhu:

12. Kufunga Nezvezvakatipoteredza:

Zvakakosha kuziva kuti hunhu chaihwo uye mashandisirwo e starch ethers zvinogona kusiyana zvichienderana nerudzi rwechinjo uye mashandisirwo azvinoda kuitwa. Vagadziri vanopa ruzivo rwakadzama rwehunyanzvi rwemhando yega yega ye starch ether kutungamira vanogadzira mukusarudza mhando yakakodzera mashandisirwo avo chaiwo.
