Eteri y'ibirayi ni iki?

Ifu ya sitashi ni ubwoko bwa sitashi bwahinduwe, karubohidrati ikomoka ku bimera. Ihinduka rikubiyemo imikorere ya shimi ihindura imiterere ya sitashi, bigatuma habaho umusaruro ufite imiterere myiza cyangwa ivuguruye. Ifu ya sitashi ikoreshwa cyane mu nganda zitandukanye bitewe n'imiterere yayo yihariye. Amwe mu moko asanzwe ya sitashi harimo hydroxyethyl starch (HES), hydroxypropyl starch (HPS), na carboxymethyl starch (CMS). Dore ibintu by'ingenzi bya sitashi:

1. Guhindura imiti:

• Ifu ya Hydroxyethyl (HES): Muri HES, amatsinda ya hydroxyethyl yinjizwa muri molekile ya sitashi. Uku guhinduka kongera ubushobozi bwayo bwo gushonga mu mazi no gutuma ikoreshwa mu miti, nk'umuvuduko wongera ingano ya plasma, no mu zindi porogaramu.
• Ifu ya Hydroxypropyl Sitachi (HPS): HPS ikorwa binyuze mu gushyira amatsinda ya hydroxypropyl mu miterere ya sitachi. Iyi mpinduka irushaho kunoza imiterere nko gushonga kw'amazi no gukora filime, bigatuma igira akamaro mu nganda nk'ibiribwa, imyenda, n'ubwubatsi.
• Ifu ya Carboxymethyl (CMS): CMS ikorwa binyuze mu gushyira amatsinda ya carboxymethyl mu ngirabuzimafatizo za sitashi. Iyi mpinduka itanga imiterere nko kunoza uburyo amazi abikwamo, kwiyongera no kugumana ubuziranenge, bigatuma igira akamaro mu bikorwa nk'ibirungo, imyenda, n'imiti.

2. Gushonga kw'amazi:

• Muri rusange, eteri za sitashi zigaragaza uburyo bwo gushonga neza mu mazi ugereranije n’iza sitashi gakondo. Uku gushonga kurushaho ni ingirakamaro mu buryo bwo gushonga aho bisaba gushonga vuba cyangwa gukwirakwira mu mazi.

3. Imiterere y'ubucucike n'ubwinshi bw'ibice:

• Eteri za sitashi zikora nk'ibinyabutabire bifasha mu kongera ubushyuhe, ibyo bikaba ingirakamaro mu gukoresha nk'ibirungo, irangi, n'ibiribwa.

4. Ubushobozi bwo Gutunganya Filimi:

• Hari eteri zimwe na zimwe za starch, cyane cyane hydroxypropyl starch, zigaragaza ubushobozi bwo gukora filime. Ibi bituma zikoreshwa aho gukora filime nto kandi yoroshye byifuzwa, nko mu nganda zikora ibiribwa n'imiti.

5. Imiterere yo Gutuza no Guhuza:

• Eteri za sitashi zikunze gukoreshwa nk'ibikomeza no gufatanya mu buryo butandukanye. Zifasha kunoza uburyo emulsion zigumana kandi zigafasha mu guhuza ibicuruzwa nk'ibinini by'imiti.

6. Porogaramu zo gufata neza:

• Eteri z'ibinyampeke zikoreshwa mu gufunga, haba mu nganda z'ibiribwa (urugero, mu bisimbura gum arabic) ndetse no mu bicuruzwa bitari ibyo kurya (urugero, mu mpapuro no mu gufunga).

7. Ingano y'imyenda:

• Mu nganda z'imyenda, eteri za starch zikoreshwa mu gupima ingano kugira ngo zongere imbaraga n'uburemere bw'ubudodo mu gihe cyo kuboha.

8. Imikoreshereze y'imiti:

• Hari eteri za sitashi zikoreshwa mu miti. Urugero, sitashi ya hydroxyethyl ikoreshwa nk'umusemburo wongera ubwinshi bw'amaraso mu maraso.

9. Ubwubatsi n'ibikoresho by'ubwubatsi:

• Eteri za sitashi, cyane cyane sitashi ya hydroxypropyl na sitashi ya carboxymethyl, zikoreshwa mu bwubatsi, cyane cyane mu byuma byumye bivanze na morti. Zifasha mu kunoza uburyo bwo gufatana, gukora neza no kubika amazi.

10. Inganda z'ibiribwa:

11. Kubora kw'ibinyabuzima:

12. Ibijyanye n'ibidukikije:

Ni ngombwa kumenya ko imiterere yihariye n'ikoreshwa rya starch ethers bishobora gutandukana bitewe n'ubwoko bw'impinduka n'ikoreshwa ryabyo. Abakora batanga ibisobanuro birambuye bya tekiniki kuri buri bwoko bwa starch ether kugira ngo bayobore abakora formulaires mu guhitamo ubwoko bukwiriye gukoreshwa muri rusange.
