Kedu ihe bụ Starch Ether?

Starch ether bụ ụdị starch emezigharịrị, carbohydrate sitere na osisi. Mgbanwe ahụ gụnyere usoro kemịkalụ na-agbanwe nhazi nke starch, na-ebute ngwaahịa nwere njirimara emelitere ma ọ bụ gbanwee. Starch ethers na-achọta ebe niile na ngwa ụlọ ọrụ dị iche iche n'ihi njirimara ha pụrụ iche. Ụfọdụ ụdị starch ethers a na-ahụkarị gụnyere hydroxyethyl starch (HES), hydroxypropyl starch (HPS), na carboxymethyl starch (CMS). Nke a bụ akụkụ ndị bụ isi nke starch ethers:

1. Ngbanwe kemịkalụ:

• Hydroxyethyl Starch (HES): Na HES, a na-ewebata otu hydroxyethyl na molekul starch. Mgbanwe a na-eme ka mmiri dị ike ya na-eme ka ọ dị mma maka iji ọgwụ eme ihe, dị ka ihe na-ebuwanye ibu plasma, na ngwa ndị ọzọ.
• Hydroxypropyl Starch (HPS): A na-emepụta HPS site na iwebata otu hydroxypropyl na nhazi starch. Mgbanwe a na-eme ka ihe ndị dị ka mmiri solubility na ike imepụta ihe nkiri, na-eme ka ọ baa uru na ụlọ ọrụ dị ka nri, textiles, na ihe owuwu.
• Carboxymethyl Starch (CMS): A na-emepụta CMS site na iwebata otu carboxymethyl na ụmụ irighiri starch. Mgbanwe a na-enye ihe ndị dị ka njigide mmiri ka mma, nkwụsi ike, na nkwụsi ike, na-eme ka ọ baa uru na ngwa dị ka adhesives, textiles, and pharmaceuticals.

2. Mmiri Solubility:

• Starch ethers na-egosipụtakarị solubility mmiri dị mma ma e jiri ya tụnyere starch ala. Nke a emelitere solubility bara uru na usoro ebe a chọrọ mgbasa ngwa ngwa ma ọ bụ mgbasa na mmiri.

3. Viscosity na Njirimara Njirimara:

• Starch ethers na-eje ozi dị ka ndị dị irè thickeners dị iche iche formulations. Ha na-enye aka n'ịbawanye viscosity, nke bara uru na ngwa ndị dị ka adhesives, mkpuchi, na ngwaahịa nri.

4. Ikike imepụta ihe nkiri:

• Ụfọdụ starch ether, karịsịa hydroxypropyl starch, na-egosipụta ihe na-emepụta ihe nkiri. Nke a na-eme ka ha dị mma maka ngwa ebe a na-emepụta ihe nkiri dị mkpa, na-agbanwe agbanwe, dị ka na nri na ụlọ ọrụ ọgwụ.

5. Nkwụsi ike na Njirimara Njirimara:

• A na-ejikarị ethers starch eme ihe dị ka ndị na-eme ka ahụ sie ike na ndị na-ejikọta ya n'ụdị dị iche iche. Ha na-enyere aka melite nkwụsi ike nke emulsions ma na-enye aka na ịdị n'otu nke ngwaahịa dị ka mbadamba ọgwụ.

6. Ngwa nrapado:

• A na-ahụta ethers starch na nrapado, ma n'ụlọ ọrụ nri (dịka ọmụmaatụ, na chịngọm arabic nnọchi) yana ngwa anaghị eri nri (dịka ọmụmaatụ, na mpempe akwụkwọ na nkwakọ ngwaahịa).

7. Nhazi akwa:

• N'ime ụlọ ọrụ textiles, a na-eji ether starch eme ihe n'ịhazi nhazi iji meziwanye ike na ire ụtọ nke yarn n'oge a na-akpa ákwà.

8. Ngwa ọgwụ:

• A na-eji ụfọdụ ether starch arụ ọrụ na usoro ọgwụ. Dịka ọmụmaatụ, a na-eji starch hydroxyethyl mee ihe dị ka ihe na-agbasa olu plasma.

9. Ihe owuwu na ihe owuwu ụlọ:

• Starch ethers, karịsịa hydroxypropyl starch na carboxymethyl starch, na-eji na-ewu ụlọ ọrụ, karịsịa na akọrọ mix ngwa agha formulations. Ha na-enye aka n'ịkwado mmachi, ịrụ ọrụ, na njide mmiri.

10. Ụlọ ọrụ nri:

12. Ihe gbasara gburugburu ebe obibi:

Ọ dị mkpa iburu n'obi na njirimara na ngwa nke starch ethers nwere ike ịdịgasị iche dabere n'ụdị mgbanwe na ihe eji eme ya. Ndị na-emepụta ihe na-enye nkọwa nkọwa zuru ezu maka ụdị starch ether ọ bụla iji duzie ndị na-emepụta ihe na ịhọrọ ụdị kachasị mma maka ngwa ha kpọmkwem.
