Hydroxypropyl methylcellulose-HPMC

Hydroxypropyl methylcellulose (HPMC)bụ ngwa dị iche iche nwere ọtụtụ ngwa n'ofe ụlọ ọrụ dị iche iche, gụnyere ọgwụ, nri, ihe ịchọ mma, ihe owuwu, na ndị ọzọ.

Ngwakọta kemịkalụ na nhazi:
HPMC bụ ọkara sịntetik, inert, polymer viscoelastic nke sitere na cellulose sitere na mgbanwe kemịkalụ. Ọ mejupụtara nkeji irighiri glucose molecule ugboro ugboro, nke yiri cellulose, yana ndị ọzọ hydroxypropyl na methyl otu jikọtara na cellulose n'azụ. Ogo nke nnọchi (DS) nke otu ndị a na-ekpebi njirimara HPMC, gụnyere solubility, viscosity, na omume gelation.

Usoro nrụpụta:
Ngwakọta nke HPMC gụnyere ọtụtụ usoro. Na mbụ, a na-emeso cellulose na alkali iji mee ka ìgwè hydroxyl rụọ ọrụ. Mgbe nke ahụ gasịrị, a na-emeghachi omume propylene oxide na cellulose na-arụ ọrụ iji webata otu hydroxypropyl. N'ikpeazụ, a na-eji methyl chloride na-ejikọta otu methyl na cellulose hydroxypropylated, na-eme ka e nwee HPMC. Enwere ike ịchịkwa DS nke hydroxypropyl na methyl dị iche iche n'oge usoro mmepụta iji kwado njirimara nke HPMC maka ngwa ngwa.

Njirimara anụ ahụ:
HPMC bụ ntụ ntụ na-acha ọcha na nke na-acha ọcha nke nwere ezigbo mmiri solubility. Ọ bụ soluble na ma mmiri oyi na mmiri ọkụ, na-emepụta ihe ngwọta doro anya, viscous. The viscosity nke HPMC ngwọta dabere na ihe ndị dị ka molekụla arọ, ogo nke nnọchi, na itinye uche. Na mgbakwunye, HPMC na-egosipụta omume pseudoplastic, nke pụtara na viscosity ya na-ebelata n'okpuru nrụgide shiee, na-eme ka ọ dabara maka ngwa dị ka ndị na-eme akwa, ndị na-eme ihe ike, na ndị na-eme ihe nkiri.

Ngwa:
Ngwa ahịa ọgwụ:HPMCa na-eji ya eme ihe n'ụdị usoro ọgwụ dị ka ihe nchikota, ihe nkiri mbụ, onye na-agbasasị, na onye na-ewepụta ihe na-achịkwa ya na mbadamba nkume, capsules, na usoro nhazi. Ọdịdị ya na-adịghị agwụ agwụ, ndakọrịta na ihe ndị na-emepụta ọgwụ na-arụ ọrụ (APIs), na ike ịmegharị kinetics ntọhapụ ọgwụ na-eme ka ọ bụrụ ihe dị mkpa na usoro nnyefe ọgwụ.

Ụlọ ọrụ nri: N'ụlọ ọrụ nri, a na-eji HPMC eme ihe dị ka ihe na-agbapụta, emulsifier, stabilizer, and gelling agent na ngwaahịa dị iche iche dị ka sauces, uwe, desserts na ihe ebe a na-eme achịcha. Ọ na-eme ka udidi ahụ dịkwuo mma, na-eme ka ọnụ ya dịkwuo mma, ma na-enye nkwụsi ike na nhazi nri na-agbanweghị uto ma ọ bụ isi.

Ihe ịchọ mma: A na-etinye HPMC n'ime usoro ịchọ mma dị ka ihe nkiri bụbu, ihe na-agbapụta, na onye na-akwụsịtụ ihe na ude, lotions, shampoos, na ngwaahịa nlekọta onwe onye ndị ọzọ. Ọ na-enye viscosity, na-eme ka mgbasawanye, ma na-eme ka nkwụsi ike ngwaahịa dịkwuo mma ma na-ebuga uru na-edozi ahụ na akpụkpọ ahụ na ntutu.

Ụlọ ọrụ na-ewu ihe: N'ime ụlọ ọrụ ihe owuwu, a na-eji HPMC eme ihe dị ka ihe na-agbapụta mmiri, onye na-ejigide mmiri, na ihe na-arụ ọrụ na-arụ ọrụ n'ime ụrọ ndị dabeere na ciment, adhesives tile, plasta, and grouts. Ọ na-eme ka arụ ọrụ dịkwuo mma, na-ebelata ikewapụ mmiri, na-eme ka adhesion dịkwuo mma, na-eme ka ihe ụlọ na-adịgide adịgide na nke dị elu.

Ngwa ndị ọzọ: HPMC na-achọta ngwa n'ụdị dị iche iche dị ka mbipụta textile, ceramik, nhazi agba, na ngwaahịa ugbo. Ọ na-eje ozi dị ka onye na-eme ihe na-eme ka ọ dị arọ, onye na-emegharị rheology, na ihe nkedo na ngwa ndị a, na-enye aka na arụmọrụ ngwaahịa na ịdị mma.

Hydroxypropyl methylcellulose (HPMC)bụ polymer multifunctional nwere ngwa zuru ebe niile na ụlọ ọrụ dị iche iche n'ihi nchikota pụrụ iche nke ihe onwunwe, gụnyere mmiri solubility, njikwa viscosity, ikike imepụta ihe nkiri, na biocompatibility. Ntughari ya na ndakọrịta ya na ihe dị iche iche na-eme ka ọ bụrụ ihe dị mkpa na ọgwụ, ngwaahịa nri, ihe ịchọ mma, na ihe owuwu, na ndị ọzọ. Ka nyocha na ọganihu teknụzụ na-aga n'ihu, a na-atụ anya ịba uru nke HPMC ga-agbasawanye, na-ebuwanye ihe ọhụrụ na ịkwalite arụmọrụ ngwaahịa n'ofe mpaghara dị iche iche.
