Gịnị bụ akụrụngwa kemịkal nke hpmc hypromose?

Hypromellose, a makwaara dị ka hydropyylthylthylthylthyl, bụ polymer na-ejikọ ọnụ site na cellose. A na-ejikarị ya na ọgwụ, nri na ụlọ ọrụ ịchọ mma dị ka nke ukwu, emulsifier na ihe mkpuchi. HPMC bụ ihe na-anaghị egbu egbu na ihe na-abụghị nke na-egbu egbu, na-eme ka ọ bụrụ nchekwa na gburugburu ebe obibi.

1. Mmiri solubility

HPMC bụ soluble na mmiri ma na-etolite ngwọta doro anya ma ọ bụ obere opalescent. Mgbalị nke HPMC dabere na ọkwa ọkwa viscosity ya, oke molecular na ogo nke dochie. Ngalaba viscosity dị elu na oke ogo molecular adịghị agbanye obere akara ule. Ogo nke dochie ọnụ ọgụgụ nke hydropyyl na methyl jikọtara ọnụ na HPMC Cellulose Backbone. Nke dị elu nke nnọchi, belata mmiri akụkụ ahụ.

2. Mmegharị kemịkal

HPMC bụ kemịkal siri ike ma ọ naghị emeghachi omume na kemịkal nke organic. Ọ na-eguzogide ọgwụ alkalis, acid na-adịghị ike na ọtụtụ ihe mgbaze ndị ọfụma. Agbanyeghị, HPMC na-emegharị acid siri ike na ndị ọrụ oxidizing, na-eduga na mmebi ya na ọnwụ nke arụmọrụ ya. Ya mere, a na-atụ aro ka ịzere ikpughe HPMC iji sie acid ma ọ bụ ndị na-eme oxidizing.

3. Njirimara nke Film

HPMC nwere ezigbo ihe nkiri na-akpụ akpụ akpụ ma sie ike maka mkpọda mbadamba, kwagide mkpuchi na-enweghị isi na njigide. Ihe nkiri a na-agbanwe site na Hpmc na-agbanwe agbanwe, transperent ma dịkwa mma. Ihe nkiri a na-egbochikwa mmebi nke ihe dị na mbadamba ma ọ bụ capsule.

Dabere na ọkwa viscosity ya, HPMC na-aga n'ihu ikuku na-aga mgbe a na-agba mmiri na mmiri karịa oke okpomọkụ. Ọnọdụ okpomọkụ ahụ sitere na 50 Celsius C ruo 90 Celsius C. Gel guzobere nke HPMC na-agbanwe agbanwe, nke pụtara enwere ike gbazee azụ na steeti mmiri site na jụrụ. Ngwongwo a na - eme HPMC adabara maka iji usoro a na - achịkwa ya, ebe enwere ike wepụta ọgwụ a ka a ga - ewepụta ọgwụ ahụ n'otu okpomọkụ.

5. Njirimara Rhioloul

HPMC gosipụtara omume pseudoplastic, nke pụtara na viseth ya na-agbadata na ịba ụba nke ya. Ngwongwo a na - eme HPMC adabara maka iji dị ka nke na - agbaze ma sie ike na nri na ịchọ mma. A na-ejikwa HPMC mee ihe dị ka onye na-eche echiche n'ihi omume ya, nke pụtara na viocosis ya na-ebelata n'okpuru nrụgide na-aga n'ihu.

HPMC bụ ihe dị iche iche na nchekwa na akụrụngwa kemịkal dị mma. Mmiri mmiri ya, ihe nkwụsi ike, akụrụngwa na-akpụ akpụ, na-eme ihe nkiri na ihe na-egbu egbu na-eme ka ọ bụrụ nhọrọ ama ama na ụlọ ọrụ dị iche iche. HPMC bụkwa ihe na-ewu ewu na gburugburu ebe obibi, na-eme ya nhọrọ na-adịgide adịgide.
