Hydroxypropyl Methylcellulose (HPMC) bụ ihe na-emepụta cellulose nwere ọtụtụ ihe na-eme ka ọ baa uru na ụlọ ọrụ dị iche iche. Nke a bụ njirimara izugbe nke HPMC:

Ọdịdị kemịkal:

HPMC bụ polymer synthetic nke na-enweta site na cellulose, polymer eke dị na mgbidi cell osisi.

Usoro kemịkalụ nke HPMC gụnyere hydroxypropyl na methyl dị iche iche jikọtara na ọkpụkpụ azụ cellulose.

Solubility:

HPMC bụ soluble na mmiri, na-akpụ a doro anya ngwọta, nke na-eme ka ọ dị mfe itinye n'ime aqueous formulations.

Viscosity:

Otu n'ime ihe ndị bụ isi nke HPMC bụ ikike ya ịgbanwe viscosity. Ọ nwere ike na-enye ndim ihe ngwọta na nhazi, na-enye aka n'ịdị mma na ịrụ ọrụ.

Ịme ihe nkiri:

HPMC nwere ihe na-emepụta ihe nkiri, nke na-eme ka ọ baa uru na ngwa ebe a na-achọ ịmepụta ihe nkiri nchebe ma ọ bụ ihe jikọrọ ọnụ.

Thermal Gelation:

HPMC na-egosiputa gelation thermal, nke pụtara viscosity ya na-abawanye na okpomọkụ. A na-ejikarị ihe onwunwe a eme ihe n'ụdị mwepụta ọgwụ a na-achịkwa.

Ọrụ elu:

HPMC nwere ike inwe surfactant-dị ka Njirimara, na-eme ka emulsification na dispersion na ụfọdụ formulations.

Nkwụsi ike:

HPMC na-enye aka na nkwụsi ike nke suspensions, emulsions, na usoro ndị ọzọ site na igbochi mbelata ma ọ bụ nkewa.

Ndokwa mmiri:

HPMC nwere ikike idowe mmiri, na-eme ka ọ baa uru na ngwa ebe idobe mmiri dị mkpa, dị ka ihe owuwu ụlọ.

Adhesion:

N'ụlọ ọrụ dị iche iche, HPMC na-eme ka adhesion dịkwuo mma, ma na ihe owuwu dị ka ngwa agha ma ọ bụ na mkpuchi na adhesives.

Ike kemịkalụ:

HPMC bụ kemịkalụ na-adịghị agwụ agwụ, nke pụtara na ọ naghị emeghachi omume na ihe ndị ọzọ dị na nhazi, na-eme ka nkwụsi ike na ndakọrịta na ọtụtụ ihe.

Mmetụta pH:

Njirimara nke HPMC nwere ike imetụta pH nke ngwọta ma ọ bụ nhazi. Ọ na-akwụsikarị ike karịa oke pH sara mbara.

Nkwụsi ike okpomọkụ:

A na-ewere HPMC dị ka ihe na-emebi emebi, nke nwere ike ịba uru na ụfọdụ ngwa gburugburu ebe obibi na nke na-adigide.

Ngwongwo ndị a n'ozuzu ha na-eme HPMC ka ọ bụrụ polima nke a na-ejikarị eme ihe na ụlọ ọrụ dịka ọgwụ, ihe owuwu, nri, ihe ịchọ mma, na ndị ọzọ. Ya ike gbanwee rheological na ọtọ Njirimara nke formulations na-eme ka ya sara applicability.
