Yintoni umahluko phakathi kwe-starch ether kunye ne-cellulose ether?

I-ether yesitatshi kunye ne-cellulose ether zombini luhlobo lwe-ether ephuma kwimizi-mveliso eyahlukeneyo, ngakumbi kulwakhiwo kunye nokwaleka. Ngelixa babelana ngezinto ezifanayo malunga nokuba ziipolima ezinyibilikayo emanzini ezinokuqina kunye nokuzinzisa iipropathi, kukho umahluko osisiseko phakathi kwazo, ikakhulu kumthombo wazo kunye nokwakheka kweekhemikhali.

IEtere yesitatshi:

1. Umthombo:
- Imvelaphi yeNdalo: Isitashi se-ether sithathwe kwi-starch, eyi-carbohydrate efumaneka kwizityalo. Isitatshi siqhele ukutsalwa kwizityalo ezifana nombona, iitapile, okanye icassava.

2. Ulwakhiwo lweMichiza:
- Ukubunjwa kwePolymer: Isitashi yipolysaccharide eyenziwe ngeeyunithi ze-glucose ezidityaniswe ngamabhondi e-glycosidic. Isitatshi se-ethers zizinto eziphuma kwistatshi ezilungisiweyo, apho amaqela e-hydroxyl kwimolekyuli yesitatshi athatyathwa endaweni yamaqela e-ether.

3. Usetyenziso:
- Ishishini lolwakhiwo: Isitatshi ethers sisoloko sisetyenziswa kushishino lokwakha njengezongezo kwimveliso esekwe kwigypsum, iimbumba, kunye nemathiriyeli esekwe kwisamente. Banegalelo ekuphuculeni ukusebenza, ukugcinwa kwamanzi, kunye nokubambelela.

4. Iintlobo eziqhelekileyo:
- I-Hydroxyethyl Starch (HES): Olunye uhlobo oluqhelekileyo lwe-starch ether yi-hydroxyethyl starch, apho amaqela e-hydroxyethyl aziswa ukuguqula isakhiwo se-starch.

I-Cellulose Ether:

1. Umthombo:
- Imvelaphi yeNdalo: I-ether ye-cellulose ivela kwi-cellulose, i-polymer yendalo efumaneka kwiindonga zeeseli zezityalo. Iyinxalenye enkulu yeendonga zeeseli zesityalo kwaye ikhutshwe kwimithombo efana ne-pulp yomthi okanye ikotoni.

2. Ulwakhiwo lweMichiza:
- Ukubunjwa kwePolymer: I-Cellulose i-polymer yomgca equkethe iiyunithi ze-glucose ezidityaniswe ngamabhondi e-β-1,4-glycosidic. I-cellulose ethers ziphuma kwi-cellulose, apho amaqela e-hydroxyl kwi-molecule ye-cellulose aguqulwa kunye namaqela e-ether.

3. Usetyenziso:
- Ishishini lolwakhiwo: I-cellulose ethers ifumana ukusetyenziswa ngokubanzi kushishino lokwakha, efana ne-starch ethers. Zisetyenziswa kwimveliso esekwe kwisamente, izinto zokuncamathelisa iithayile, kunye nodaka ukunyusa ukugcinwa kwamanzi, ukusebenza kunye nokuncamathela.

4. Iintlobo eziqhelekileyo:
- I-Hydroxyethyl Cellulose (HEC): Olunye uhlobo oluqhelekileyo lwe-cellulose ether yi-hydroxyethyl cellulose, apho amaqela e-hydroxyethyl angeniswa ukuguqula isakhiwo se-cellulose.
- I-Methyl Cellulose (MC): Olunye uhlobo oluqhelekileyo yi-methyl cellulose, apho amaqela e-methyl aziswa khona.

Umahluko oPhambili:

1. Umthombo:
- Isitatshi ether sithathwe kwi-starch, i-carbohydrate efumaneka kwizityalo.
- I-ether ye-cellulose ivela kwi-cellulose, inxalenye enkulu yeendonga zeeseli zesityalo.

2. Ulwakhiwo lweMichiza:
- Isiseko se-polymer ye-starch ether isitashi, i-polysaccharide eyenziwe ngeeyunithi ze-glucose.
- Isiseko se-polymer ye-cellulose ether yi-cellulose, i-polymer ecacileyo eyenziwe ngeeyunithi ze-glucose.

3. Usetyenziso:
- Zombini iintlobo zeetha zisetyenziswa kushishino lokwakha, kodwa usetyenziso oluthile kunye nolwakhiwo lunokwahluka.

4. Iintlobo eziqhelekileyo:
- I-Hydroxyethyl starch (HES) kunye ne-hydroxyethyl cellulose (HEC) yimizekelo yalezi ziphuma ze-ether.

ngelixa isitashi se-ether kunye ne-cellulose ether zombini iipolymers ezinyibilikayo zamanzi ezisetyenziswa njengezongezo kwizicelo ezahlukeneyo, umthombo wazo, isiseko sepolymer, kunye nezakhiwo ezithile zeekhemikhali ziyahluka. Lo mahluko unokuphembelela ukusebenza kwabo kwimiqulu ethile kunye nezicelo.
