Ọdịiche dị n'etiti hydroxypppppyl starch na hydropyylthyl cellulose

Hydroxypyl Starch na hydroxyl methyl methyl celluse (HPMC) na-ejikwa ọrụ dị iche iche, gụnyere nri ọgwụ, ọgwụ, na owuwu. Ọ bụ ezie na ha na-ekerịta ụfọdụ myirịta, ha nwere ọdịiche dị na usoro nke usoro kemịkalụ, Njirimara na ngwa. Ndị a bụ isi ọdịiche dị n'etiti Hydroxypyl Starch na HPMC:

Ihe Okike:

1. Hydroxypyl Starch:
   • Hydroxypyl Starch bụ stachi gbanwetụrụ site na iwebata otu hydropyyl na steepụ stachi.
   • Starch bụ polsaccharide mejupụtara ihe ejikọtara ọnụ site na agbụ Glycosidic. Hydroxylopylation na-agụnye ihe nnọchi nke otu Hydroxyl (-OH) na usoro starch molekul na hydroxyl (-CH2chohchyl (-ch2chohchyl (-CH2chohchyl (-ch2chohchyl (-CH2chohchyl (-ch2chohchyl
2. Hydroxypylthylthth methyl cellulose (hpmc):
   • HPMC bụ mgbanwe sellilose ether eert e nwetara site na iwebata ma hydroxyl nathyl na Methyl na cellulose molekuse molulu.
   • Cellulose bụ polysiccharide mejupụtara akụkụ glucose jikọtara ọnụ site na β (1 → 4) Glycosidic Agbụ. Ndị otu HydroxyLip na-ewebata Hydropyl (-ch2chohch3) Otu dị iche iche, ka metylition na-ewepụta methyl (-ch3) Otu dị na Cellulose Backbone.

Njirimara:

1. Solubality:
   • Hydroxypyl Starch na-abụkarị mmiri na-ekpo ọkụ ma nwee ike igosipụta ndọtị na mmiri oyi.
   • HPMC bụ soluble na mmiri oyi na mmiri ọkụ ma na-ekpo ọkụ, na-akọwapụta ihe ngwọta doro anya. A na - adabere na HPMC dabere na ogo nke dochie anya (DS) na oke molecular nke polymen.
2. Viscosity:
   • Hydroxypyl Starch nwere ike igosipụta Njirimara Valcosity - mana viscosis ya atụnyere HPMC.
   • A maara HPMC maka ezigbo ihe ndị na-agbanwe agbanwe. Enwere ike idozi viscosity nke HPMC nwere ike ịgbanwe site na ijigide ịta polymen ịta, ds, na oke molecular.

Ngwa:

1. Nri na ogwu:
   • A na-ejikarị hydroxypyl starch dị ka nke na-emekarị, kwụsie ike, na ndị na-ahụ maka nri na ngwaahịa nri dịka ofe, na ụtọ. Enwere ike iji ya na usoro ọgwụgwọ ọgwụ.
   • A na-eji HPMC mee ihe n'ọtụtụ ebe, ọtụtụ ihe na-eme ọgwụ, na ihe ịchọ mma dị ka nke na-eme ka ala, emulsifier, mmachi, na onye na-ahụ maka ịhapụ ya. A na-ahụkarị ya na ngwaahịa dịka mbadamba, ugboro ugboro, ude, na ihe nlekọta onwe gị.
2. Ihe owuwu na ulo:
   • A na-eji HPMC na ụlọ ọrụ owuwu dị ka ihe mgbakwunye na ngwaahịa ciment dị ka tile adhesives, ndị na-ajụ oyi, na-atụgharị, na compars. Ọ na-enye njigide mmiri, ọrụ, adresion, na arụmọrụ dị mma na ngwa ndị a.

Nkwubi:

Ọ bụ ezie na hydroxyyl starch na HPMC na-agbanwe agbanwe na polisaccharides yiri nke ahụ, ha nwere usoro kemịkal dị iche, Njirimara na Ngwa. A na-ejikarị ngwa nri na ngwa ọgwụ, ebe HPMC na-ahụ ọtụtụ nri, ọgwụ, ihe ịchọ mma na ihe owuwu. Nhọrọ dị n'etiti Hydroxyl Starch na HPMC dabere na usoro akọwapụtara nke ngwa achọrọ.
