Umahluko phakathi kwe-Hydroxypropy starch ether or kunye ne-hydroxypropyl methylcelcelcelgalose ekwaziseni

I-Hydroxypropy starch ether (i-HPSE) kwayeHydroxypropyl methylcelculose (hpmc)Zombini iintlobo ze-polymers ezinyibilikayo zamanzi zihlala zisetyenziswa kwishishini lokwakha. Ngelixa babelana ngokufana, kukho umahluko ophambili kwiikhemikhali kunye neempawu zentsebenzo. Apha ngezantsi kukho umahluko omkhulu phakathi kwe-hydroxypropy starch ether orten kunye ne-hydroxypropyl methylcelcelcelose kwizicelo zokwakha:

I-1. Ubume bemichiza:

• I-HPSE (i-hydroxypropy stanch ether):
  • Ithathwe kwistatshi, eyicarbohydrate evela kwimithombo emininzi yezityalo.
  • Iguqulwe nge-hydroxyypropy yokuphucula iipropathi zayo.
• I-HPMC (Hydroxypropyl Methylcelcelcelose):
  • Ithathwe kwi-seluplose, i-polymer yendalo efumaneka kwiindonga zeseli.
  • Iguqulwe nge-hydroxyypropy kunye ne-methyred ukufezekisa iipropathi eziyimfuneko.

I-2. Impahla yomthombo:

• I-HPSE:
  • Ifunyenwe kwimithombo yesitayile esisekwe kwisityalo, njengengqolowa, i-potato, okanye iTapioca.
• I-HPMC:
  • Ithathwe kwimithombo yeselfowuni esekwe kwi-selseulose, ihlala i-pulp okanye umqhaphu.

3. Ukungasebenzi:

• I-HPSE:
  • Ngokwesiqhelo bonisa ukubenzela amandla okuba ngamanzi, ukuvumela ukusasazeka ngokulula kwiziko elisekwe emanzini.
• I-HPMC:
  • Inyibilikiswe ngamanzi, yenza izisombululo ezicacileyo emanzini.

4. Ukuhla kwe-shirmal:

• I-HPSE:
  • Ezinye i-hydroxypropy starch eves zinokubonakalisa iipropathi zokungalawuleki, apho ukubonwa kwesisombululo kunyuka ngobushushu.
• I-HPMC:
  • Ngokubanzi ayibonisi ukungqubana kwe-thermal, kwaye i-viscofity yayo ihlala izinzile kulo lonke amaqondo obushushu.

I-5. Iipropathi zokwenza ifilimu:

• I-HPSE:
  • Unokwenza iifilimu ngokuguquguquka okuhle kunye ne-adherions.
• I-HPMC:
  • Vavanya iipropathi zokwenza ifilimu, igalelo kuphuculo lokuphucula kunye nokudibana kwifom yokwakha.

6. Indima ekwakhiweni:

• I-HPSE:
  • Isetyenziswe kwizicelo zokwakha zokugcina amanzi, ukugcinwa kwamanzi, kunye neepropathi zokunamathela. Inokuqeshwa kwiimveliso ezisekwe kwi-gypsim ezisekwe, ezikrwada kunye nemihlambi.
• I-HPMC:
  • Isetyenziswe ngokubanzi ngokwakhiwa kwendima yayo njenge-gicker, iarhente yokugcina amanzi, kunye nokuphucula amandla. Ihlala ifumaneka kwizifakelo ezisekwe kwisamente, amachaphaza e-gile, i-gris, kunye nezinye iindlela.

7. Ukukhetha:

• I-HPSE:
  • Ihambelana noluhlu lwezinye izinto zongezwa kunye nezixhobo.
• I-HPMC:
  • Vavanya ukuhambelana ngokuchanekileyo nezixhobo ezahlukeneyo zokwakha kunye nokongezwa.

8. Ukuseta ixesha:

• I-HPSE:
  • Inokuba nefuthe kwixesha lokwenziwa kwamaxesha okwakha.
• I-HPMC:
  • Inokuphembelela ixesha lokutsala kunye nezinye iimveliso ezinobume.

9. Ukuguquguquka:

• I-HPSE:
  • Iifilimu ezenziwa zii-hydroxypropy zeetarches starch ezintandathu zithande ukuba bhetyebhetye.
• I-HPMC:
  • Inegalelo kuguquko kunye nokunganyangeki kwifom yokwakha.

10. Iindawo zesicelo:

• I-HPSE:
  • Ifunyenwe kwiimveliso ezahlukeneyo zokwakha, kubandakanya i-Plaster, i-Putty, kunye nokunamathela.
• I-HPMC:
  • Iqhelekile isetyenziswa kwizifakelo ezisekwe kwisamente, amachaphaza e-gile, i-gris, kunye nezinye izixhobo zokwakha.

Ngesishwankathelo, ngelixa zombini i-hydroxyl starch ether (i-HPSE) kunye ne-hydroxypropyl methylcelcelsulose (i-HPMC) isebenza ngenjongo yokwakha, i-HPMC yekhefu, kwaye ezinye iipropathi zenziwe, kunye nokusetyenziswa kweshishini ngokwahlukeneyo. Ukukhetha phakathi kwabo kuxhomekeke kwiimfuno ezithile zezinto zokwakha kunye neempawu zokusebenza ezinqwenelekayo.
