Chii chinonzi strar ether?

Starch Ether ndeye fomu yakagadziridzwa yemarara, iyo carbohydrate inotorwa kubva kune zvidyarwa. Iko kugadziridzwa kunosanganisira makemikari maitiro ayo anoshandura chimiro chehunhu, zvichikonzera chigadzirwa neakavandudzwa kana zvakagadziridzwa zvivakwa. Starch anaitti vanowana kushandiswa kwakapararira mune dzakasiyana siyana maindasitiri ekushandisa nekuda kwehunhu hwavo hwakasarudzika hunhu. Mamwe marudzi akajairika emasimba erarch anosanganisira hydroxyll starch (hes), hydroxypruppropyl starch (HPS), uye carboxymethyl starch (cms). Heano zvinhu zvakakosha zvehunhu zvinomutsa:

1. Chemical Stification:

• HydroxytHyl Starch (Hes): Mune hes, hydroxytemsl mapoka anounzwa kune iyo starch mamorekuru. Uku kugadziridzwa kunowedzera simba rayo remvura uye kunoita kuti zviite kuti zviite kushandiswa mumishonga yemishonga, seplasma vhoriyamu inowedzera, uye mune zvimwe zvinoshandiswa.
• Hydroxyprospropyl starch (HPS): HPS inogadzirwa nekuunza hydroxpropropyl mapoka kune iyo starch. Uku kugadziridzwa kunovandudza zvivakwa zvakadai sekusarudzika kwemvura uye kugona kwemafirimu, zvichiita kuti zvive zvinobatsira mumaindasitiri senge chikafu, chimedu, uye kuvaka.
• CarboxyMethyl Starch (cms): Cms yakagadzirwa nekuunza carboxymethyl mapoka kumanonhuwa mamorekuru. Uku kushandurwa kunopa zvivakwa zvakadai sekuvandudza kwemvura kuchengetwa, kururamisa, uye kugadzikana, kuita kuti zviite zvakakosha mukunyorera senge zvinonamira, uye mishonga uye mishonga.

2. Soluby mvura:

• Starch ana vana kazhinji vanoratidza zvakavandudzwa mvura solubility yakafananidzwa nemaronda. Izvi zvinosimbiswa Solubility zvinobatsira mukuumbwa uko kukurumidza kupera kana kupararira mumvura kunodiwa.

3. Viscosity uye zvakakora zvivakwa:

• Starch anaitle vanoshanda sevanoshanda manhara mune dzakasiyana siyana mafambiro. Ivo vanopa kuti vawedzere kuwanda visikoka, izvo zvakakosha mukushandisa zvakadai sekumaodzvinyirira, kuungana, uye zvigadzirwa zvekudya.

4. Firimu-kugadzira kugona:

• Vamwe vanomutsa, kunyanya hydroxyprupropyl starch, kuratidzira mafirimu-ekuumba midziyo. Izvi zvinovaita kuti vakwanise kunyatsoita zvekushandisa uko kusikwa kwefirimu rakatetepa, rinochinjika rinodiwa, senge mune zvekudya uye maindasitiri ezvekudya nemishonga.

5. Simbisa uye kusunga midziyo:

• Starch anaitinhi vanowanzoshandiswa seStabilizer uye mabheti mune akasiyana siyana mafomu. Ivo vanobatsira kuvandudza kusimba kwemelsions uye vanopa kubatana kwezvigadzirwa semapiritsi emishonga yemishonga.

6. Zvinoshambidzika Zvikumbiro:

• Starwe anaitti vanowana kushandisa mumanesheni, ese ari muindasitiri yekudya (semuenzaniso, mune gamu arabic kutsiva) uye zvisiri-zvekudya zvekushandisa (semuenzaniso, mupepa uye kurongedza madekisi).

7. Textile sizing:

• Muindasitiri yemiindaniso, starch anaitinhi vanoshandiswa pakurongeka kwekuvandudza simba uye kuseka kweYarns panguva yekuchema.

8. Pfekceutical application:

• Rimwe starch ana vana vanoshandirwa mune mishonga yemishonga. Semuenzaniso, hydroxytHyl starch inoshandiswa seplasma vhoriyamu Excander.

9. Kuvaka uye Zvivakwa Zvekuvaka:

• Starwe anaithunyo, kunyanya hydroxyprupyl starch uye carboxymethyl starch, anoshandiswa mune yekuvaka indasitiri, kunyanya mune yakaoma musanganiswa maumbu. Ivo vanopa basa rekudzvanywa kudedera, kushanda, uye kuchengetwa kwemvura.

10. Indasitiri yechikafu:

11. Biodegradability:

12. Kufunga nezvenzvimbo:

Izvo zvakakosha kuti uzive kuti izvo zvakanangana nezvivakwa uye zvinonyadzisa zvevana vana vanogona kusiyana zvichienderana nerudzi rwekugadziridzwa uye kushandiswa kwakanangwa. Vagadziri vanopa zvakadzama technical yehunyanzvi kune imwe neimwe mhando yerarch ither kutungamira maFirnulators pakusarudza zvakanyanyisa kusiyanisa kwavo zvikumbiro.
