Chii chinonzi Starch Ether?

Starch ether imhando yakagadziridzwa ye starch, carbohydrate inotorwa kubva muzvirimwa. Iko kugadziridzwa kunosanganisira maitiro emakemikari anoshandura chimiro che starch, zvichikonzera chigadzirwa chine yakagadziridzwa kana yakagadziridzwa zvinhu. Starch ethers inowana kushandiswa kwakapararira mune akasiyana maindasitiri ekushandisa nekuda kweakasarudzika maitiro. Mamwe marudzi akajairika estarch ethers anosanganisira hydroxyethyl starch (HES), hydroxypropyl starch (HPS), uye carboxymethyl starch (CMS). Heano maitiro akakosha e starch ethers:

1. Kugadziriswa Kwemakemikari:

• Hydroxyethyl Starch (HES): MuHES, hydroxyethyl mapoka anounzwa kune iyo starch molecule. Kugadziridzwa uku kunowedzera kunyungudika kwayo kwemvura uye kunoita kuti ive yakakodzera kushandiswa mumishonga, seplasma volume expander, uye mune mamwe maapplication.
• Hydroxypropyl Starch (HPS): HPS inogadzirwa nekuunza hydroxypropyl mapoka kune starch chimiro. Iyi shanduko inovandudza zvivakwa zvakaita sekunyungudika kwemvura uye kugona kugadzira firimu, zvichiita kuti zvive zvakakosha mumaindasitiri akaita sechikafu, machira, uye kuvaka.
• Carboxymethyl Starch (CMS): CMS inogadzirwa nekuunza mapoka ecarboxymethyl kumamorekuru estarch. Kugadziridzwa uku kunopa zvivakwa zvakaita sekuvandudzwa kwekuchengetedza mvura, kukora, uye kugadzikana, zvichiita kuti ive yakakosha mumashandisirwo akaita seanonamira, machira, nemishonga.

2. Kunyungudika kwemvura:

• Starch ethers inowanzo ratidza kuve nekunyungudika kwemvura kana ichienzaniswa neyemuno starch. Uku kunyungudika kunyungudika kunobatsira mukuumbwa uko kukurumidza kunyungudika kana kupararira mumvura kunodiwa.

3. Viscosity uye thickening Properties:

• Starch ethers inoshanda seyakakobvuta inoshanda mumhando dzakasiyana siyana. Ivo vanobatsira kuwedzera viscosity, iyo yakakosha mumashandisirwo akadai seanonamira, machira, uye zvigadzirwa zvekudya.

4. Kukwanisa Kugadzira Mafirimu:

• Dzimwe starch ethers, kunyanya hydroxypropyl starch, inoratidza firimu-kugadzira zvinhu. Izvi zvinovaita kuti vakwanise kunyorera uko kugadzirwa kwefirimu rakatetepa, rinochinjika, senge mumaindasitiri ezvekudya nemishonga.

5. Kudzikamisa uye Kusunga Zvivakwa:

• Starch ethers inowanzoshandiswa sezvitsigiso uye mabhainda mumhando dzakasiyana siyana. Vanobatsira kuvandudza kugadzikana kwe emulsions uye kugovera kukubatana kwezvigadzirwa semapiritsi emishonga.

6. Adhesive Applications:

• Starch ethers inowana kushandiswa mune zvinonamira, zvese muindasitiri yezvekudya (semuenzaniso, mune chingamu arabic inotsiva) uye isiri-yechikafu maapplication (semuenzaniso, mumapepa nemapaketi ekunamira).

7. Kukura Kwemachira:

• Muindasitiri yemachira, starch ethers inoshandiswa mukugadzira saizi yekuvandudza kusimba uye kutsetseka kweshinda panguva yekuruka.

8. Pharmaceutical Applications:

• Imwe starch ether inoshandiswa mukugadzira mishonga. Semuenzaniso, hydroxyethyl starch inoshandiswa se plasma volume expander.

9. Kuvaka uye Zvishandiso zvekuvaka:

• Starch ethers, kunyanya hydroxypropyl starch uye carboxymethyl starch, anoshandiswa muindasitiri yekuvaka, kunyanya mukuoma musanganiswa wedhaka maumbirwo. Vanobatsira pakuvandudza kunamatira, kushanda, uye kuchengetedza mvura.

10. Indasitiri Yezvekudya:

11. Biodegradability:

12. Mafungiro Ezvakatipoteredza:

Izvo zvakakosha kuti uzive kuti iyo chaiyo zvivakwa uye mashandisirwo esitarch ethers anogona kusiyana zvichienderana nerudzi rwekugadzirisa uye kushandiswa kwakarongwa. Vagadziri vanopa humbowo hwakadzama hwemhando yega yega starch ether kutungamira vanogadzira mukusarudza iyo yakanyatso siyana yezvavanoshandisa.
