Yini isitashi i-ether?

Isitashi i-Ether yifomu eliguquliwe lesitashi, i-carbohydrate ethathwe ezitshalweni. Ukulungiswa kufaka izinqubo zamakhemikhali eziguqula ukwakheka kwesitashi, okuholela kumkhiqizo onezakhiwo ezithuthukisiwe noma eziguquliwe. AbakwaStarch Abather bathola ukusetshenziswa okubanzi ezinhlelweni ezahlukahlukene zezimboni ngenxa yezimpawu zabo ezihlukile. Ezinye izinhlobo ezivamile zokuthwala izitashi zifaka i-hydroxyethyl starch (hes), i-hydroxypropyl starch (HPS), kanye ne-carboxymethyyl starch (CMS). Nazi izici ezibalulekile zokuthambekela kwesitashi:

1. Ukuguqulwa kwamakhemikhali:

• I-Hydroxyyethyl Starch (HES): Ku-HES, amaqembu e-Hydroxyethyl angeniswa ku-molecule yesitashi. Lokhu kuguqulwa kuthuthukisa i-solubility yayo yamanzi futhi kwenza kube lula ukusetshenziswa emikhakheni, njengomsunguli wevolumu ye-plasma, nakwezinye izinhlelo zokusebenza.
• I-Hydroxypropyl Starch (HPS): I-HPS ikhiqizwa ukwethula amaqembu we-hydroxypropyl ekwakhiweni kwesitashi. Lokhu kuguqulwa kuthuthukisa izakhiwo ezinjengamandla we-soubity namandla efilimu, okwenza kube lusizo ezimbonini ezinjengokudla, izindwangu kanye nokwakha.
• I-Carboxymethyl Starch (CMS): I-CMS yenziwe ngethula amaqembu e-carboxymethyl kuma-molecule wesitashi. Lokhu kuguqulwa kunikeza izakhiwo ezifana nokugcinwa kwamanzi okuthuthukile, ukuqina, nokuqina, okwenza kube yigugu kuzinhlelo zokusebenza ezinjengezifiso, izindwangu, kanye nemithi.

2. I-solubity yamanzi:

• AbakwaStarch Abathathi ngokuvamile bakhombisa i-solubity yamanzi ethuthukisiwe ngokuqhathaniswa nesitashi sendabuko. Lokhu kusebenza okuthuthukisiwe kungukuzuzisa lapho kuchithwa khona noma ukuhlakazeka kwamanzi okusheshayo.

3. I-Viscosity Nezindawo Zokuqina:

• I-Starch Tashers isebenza njengezikhulu ezisebenza ngempumelelo ekunikezelweni okuhlukahlukene. Banikela ekwandeni kwe-viscosity, okubalulekile kwizicelo ezifana nokunamathela, ukumboza kanye nemikhiqizo yokudla.

4. Ikhono elenziwe ngefilimu:

• Abanye abaphethe isitashi, ikakhulukazi isitashi se-hydroxypropyl, bonisa izakhiwo ezakha amafilimu. Lokhu kubenza balungele izinhlelo zokusebenza lapho kudalwa khona i-CEDDID yefilimu emincane, eguqukayo.

I-5. Ukuqina nokubopha izakhiwo:

• AbakwaStarch Abathathi bavame ukusetshenziswa njengezitebele kanye namabhayisiki ezinhlobonhlobo zokwakheka. Basiza ukuthuthukisa ukuqina kwama-emulsions futhi banikele ekubumbeni kwemikhiqizo efana namathebulethi wezemithi.

6. Izicelo ezinamathela:

• I-Starch Heathers ithola ukusetshenziswa ezinamatheli, bobabili embonini yokudla (isib. Ku-Gum Arabic Substites) kanye nezicelo ezingezona zokudla (isib. Ephepheni nasezinamakhasi nasezinamakhasi nasezinamatheli nasemaphepheni).

7. Indwangu yendwangu:

• Embonini yezindwangu, izithambisi zesitashi zisetshenziselwa ukwenza amafomu okuthuthukisa ukuthuthukisa amandla nokubusheleleka kwentambo ngesikhathi sokuluka.

8. Izicelo zezemithi:

• Izithako ezithile ze-Starch ziqashwa ekwakhiweni kwemithi. Isibonelo, isitashi se-hydroxyyethyl sisetshenziswa njengendida yevolumu ye-plasma.

9. Izinto zokwakha nezakhayo:

• I-Starch ether, ikakhulukazi i-hydroxypropyls starch kanye nesitashi se-carboxymethyl, kusetshenziswa embonini yezokwakha, ikakhulukazi ekwakhiweni kodaka kodaka. Bafaka isandla ekunamathisweni okuthuthukile, ukusebenziseka kanye nokugcinwa kwamanzi.

10. Imboni yokudla:

11. I-BiodegradeAbility:

12. Ukucatshangelwa Kwezemvelo:

Kubalulekile ukuqaphela ukuthi izakhiwo ezithile nokusetshenziswa kwezithambisi zeStarch kungahluka ngokuya ngohlobo lokuguqulwa kanye nokusetshenziswa okuhlosiwe. Abakhiqizi bahlinzeka ngemininingwane enemininingwane yezobuchwepheshe ngohlobo ngalunye lwe-starch ether ukuqondisa ama-formalators ekukhetheni okufanele kakhulu ngezicelo zazo ezithile.
