Gịnị bụ Starch Ether?

Starch ether bụ ụdị starch agbanwere agbanwe, carbohydrate sitere na osisi. Mgbanwe a gụnyere usoro kemịkalụ nke na-agbanwe nhazi starch, na-eme ka ngwaahịa nwee ihe ndị ka mma ma ọ bụ ndị agbanwere agbanwe. A na-eji starch ether eme ihe nke ọma n'ọtụtụ ọrụ ụlọ ọrụ n'ihi njirimara pụrụ iche ha. Ụfọdụ ụdị starch ethers a na-ahụkarị gụnyere hydroxyethyl starch (HES), hydroxypropyl starch (HPS), na carboxymethyl starch (CMS). Lee akụkụ ndị bụ isi nke starch ethers:

1. Mgbanwe Kemịkalụ:

• Hydroxyethyl Starch (HES): Na HES, a na-ewebata otu hydroxyethyl na molekul starch. Mgbanwe a na-eme ka mmiri ya na-agbaze nke ọma ma mee ka ọ dị mma maka iji ya na ọgwụ, dị ka ihe na-agbasa olu plasma, na n'ọrụ ndị ọzọ.
• Hydroxypropyl Starch (HPS): A na-emepụta HPS site n'itinye otu hydroxypropyl n'ime usoro starch. Mgbanwe a na-eme ka ihe ndị dị ka mmiri na-agbaze na ikike imepụta ihe nkiri ka mma, na-eme ka ọ baa uru n'ụlọ ọrụ dịka nri, ákwà, na ihe owuwu.
• Carboxymethyl Starch (CMS): A na-emepụta CMS site n'iwebata otu carboxymethyl na molekul starch. Mgbanwe a na-enye ihe ndị dị ka ime ka mmiri dị mma, ịka mma, na nkwụsi ike, na-eme ka ọ baa uru na ngwa dịka ihe nrapado, ákwà, na ọgwụ.

2. Mmiri na-agbaze:

• Mmiri ethers na-adịkarị mma ma e jiri ya tụnyere mmiri e si n'okike nweta. Mmiri a na-agbaze nke ọma bara uru n'ụdị mmiri ebe ọ dị mkpa ka a gbazee ma ọ bụ gbasaa ngwa ngwa n'ime mmiri.

3. Njirimara Viscosity na Extracting:

• Ether starch na-arụ ọrụ dị ka ihe na-eme ka ihe sie ike nke ọma n'ọtụtụ usoro dị iche iche. Ha na-enye aka na mmụba nke viscosity, nke bara uru na ojiji dịka ihe nrapado, ihe mkpuchi, na ngwaahịa nri.

4. Ikike Ịmepụta Ihe Nkiri:

• Ụfọdụ ihe ether starch, ọkachasị hydroxypropyl starch, na-egosipụta ihe ndị na-emepụta fim. Nke a na-eme ka ha dị mma maka iji ha eme ihe ebe a chọrọ imepụta ihe nkiri dị gịrịgịrị, nke na-agbanwe agbanwe, dịka n'ụlọ ọrụ nri na ọgwụ.

5. Njirimara Ịkwụsi Ike na Njikọta:

• A na-ejikarị starch ether eme ihe dị ka ihe na-eme ka ihe sie ike ma na-ejikọta ya n'ọtụtụ usoro. Ha na-enyere aka ime ka emulsions dịkwuo mma ma na-enye aka n'ịhazi ngwaahịa dịka mbadamba ọgwụ.

6. Ngwa ndị na-arapara:

• A na-eji ihe ether starch eme ihe n'ime ihe e ji agwakọta ihe, ma n'ụlọ ọrụ nri (dịka ọmụmaatụ, n'ihe ndị e ji dochie anya chịngọm arabik) ma n'ihe ndị na-abụghị nri (dịka ọmụmaatụ, n'akwụkwọ na ihe e ji agwakọta ihe).

7. Nhazi ákwà:

• N'ụlọ ọrụ ákwà, a na-eji starch ether eme nhazi nha iji melite ike na ịdị ire ụtọ nke eriri n'oge ịkpa ákwà.

8. Ngwa Ọgwụ:

• A na-eji ụfọdụ ether starch eme ihe n'ụdị ọgwụ. Dịka ọmụmaatụ, a na-eji hydroxyethyl starch eme ihe dị ka ihe na-agbasa olu plasma.

9. Ihe owuwu na ihe owuwu ụlọ:

• A na-eji starch ethers, karịsịa hydroxypropyl starch na carboxymethyl starch, eme ihe n'ụlọ ọrụ owuwu, ọkachasị n'ụdị ngwakọta akọrọ. Ha na-enyere aka ime ka njikọ dịkwuo mma, rụọ ọrụ nke ọma, na idobe mmiri.

12. Ihe Ndị A Na-atụle Banyere Gburugburu Ebe Obibi:

Ọ dị mkpa ịmara na njirimara na ojiji nke starch ethers nwere ike ịdị iche dabere na ụdị mgbanwe na ojiji ebumnuche. Ndị nrụpụta na-enye nkọwapụta teknụzụ zuru ezu maka ụdị starch ether ọ bụla iji duzie ndị na-emepụta ihe n'ịhọrọ ụdị kachasị mma maka ojiji ha kpọmkwem.
