Ọdịiche dị n'etiti Hydroxypropyl Starch ether na Hydroxypropyl Methylcellulose na Mwube

Hydroxypropyl Starch Ether (HPSE) naHydroxypropyl Methylcellulose (HPMC)bụ ma ụdị abụọ nke mmiri-soluble polymers a na-ejikarị na-ewu ụlọ. Ọ bụ ezie na ha na-ekerịta ụfọdụ myirịta, enwere ọdịiche dị mkpa na nhazi kemịkal ha na njirimara arụmọrụ ha. N'okpuru bụ isi ihe dị n'etiti Hydroxypropyl Starch Ether na Hydroxypropyl Methylcellulose na ngwa owuwu:

1. Ọdịdị kemịkalụ:

• HPSE (Hydroxypropyl Starch Ether):
  • E sitere na starch, nke bụ carbohydrate sitere na isi mmalite osisi dị iche iche.
  • Gbanwee site na hydroxypropylation iji kwalite akụrụngwa ya.
• HPMC (Hydroxypropyl Methylcellulose):
  • E sitere na cellulose, polymer eke dị na mgbidi cell nke osisi.
  • Gbanwee site na hydroxypropylation na methylation iji nweta ihe ndị a chọrọ.

2. Isi mmalite Ihe:

• HPSE:
  • Enwetara site na isi mmalite starch nke osisi, dị ka ọka, poteto, ma ọ bụ tapioca.
• HPMC:
  • E sitere na isi mmalite cellulose sitere na osisi, mgbe mgbe osisi pulp ma ọ bụ owu.

3. Solubility:

• HPSE:
  • A na-egosiputa ezigbo mmiri solubility, na-enye ohere maka mgbasa ozi dị mfe na nhazi mmiri.
• HPMC:
  • Mmiri na-agbaze nke ukwuu, na-emepụta ngwọta doro anya na mmiri.

4. Thermal Gelation:

• HPSE:
  • Ụfọdụ hydroxypropyl starch ethers nwere ike igosipụta njirimara gelation thermal, ebe viscosity nke ngwọta na-abawanye na okpomọkụ.
• HPMC:
  • N'ozuzu, anaghị egosipụta gelation thermal, na viscosity ya na-anọgide na-akwụsi ike n'ofe oke okpomọkụ.

5. Njirimara Ndị Na-emepụta ihe nkiri:

• HPSE:
  • Nwere ike ịmepụta ihe nkiri nwere ezigbo mgbanwe na ihe nrapado.
• HPMC:
  • Na-egosiputa ihe ndị na-emepụta ihe nkiri, na-enye aka n'ịkọba mma na njikọta na nhazi ihe owuwu.

6. Ọrụ na-ewu:

• HPSE:
  • A na-eji ngwa owuwu ihe maka ịgbatị ya, njide mmiri, yana ihe nrapado ya. Enwere ike iji ya n'ọrụ na ngwaahịa gypsum, ngwa agha, na nrapado.
• HPMC:
  • A na-eji ya eme ihe na-ewu ụlọ maka ọrụ ya dị ka ihe na-agbapụta mmiri, ihe na-ejide mmiri, na nkwalite ọrụ. A na-ahụkarị ya na ngwa ngwa simenti, nrapado tile, grouts, na usoro ndị ọzọ.

7. ndakọrịta:

• HPSE:
  • Dakọtara na nso nso nke ihe mgbakwunye ihe owuwu na ihe ndị ọzọ.
• HPMC:
  • Na-egosipụta ezigbo ndakọrịta na ihe owuwu dị iche iche na mgbakwunye.

8. Nhazi oge:

• HPSE:
  • Nwere ike imetụta oge mwube nke ụfọdụ usoro ihe owuwu.
• HPMC:
  • Nwere ike imetụta nhazi oge ngwa ngwa na ngwaahịa ciment ndị ọzọ.

9. Mgbanwe:

• HPSE:
  • Ihe nkiri nke hydroxypropyl starch ethers mere na-enwekarị mgbanwe.
• HPMC:
  • Na-enye aka na mgbanwe na mgbawa mgbawa n'usoro ihe owuwu.

10. Mpaghara Ngwa:

• HPSE:
  • Achọtara ya n'ụdị ihe nrụpụta dị iche iche, gụnyere plasta, putty, na nrapado.
• HPMC:
  • A na-ejikarị simenti, ihe nrapado tile, grouts, na ihe ndị ọzọ eji arụ ụlọ.

Na nchịkọta, ebe ma Hydroxypropyl Starch Ether (HPSE) na Hydroxypropyl Methylcellulose (HPMC) na-eje ozi otu nzube na-ewu, ha dị iche iche kemịkalụ si malite, solubility àgwà, na ndị ọzọ Njirimara na-eme ka ha dabara na dị iche iche formulations na ngwa n'ime ụlọ ọrụ. Nhọrọ n'etiti ha na-adabere na ihe ndị a chọrọ kpọmkwem nke ihe owuwu ihe na njirimara arụmọrụ achọrọ.
