Hydroxypropyl Methylcellulose (HPMC) bụ mmepụta cellulose nke a na-ejikarị na nri, ọgwụ, ihe owuwu na ihe ịchọ mma. Ụdị ya kpọmkwem E15 adọtala mmasị dị ukwuu n'ihi njirimara ya pụrụ iche na ngwa obosara.
1. Njirimara anụ ahụ na nke kemịkal
Ngwakọta kemịkalụ
HPMC E15 bụ akụkụ nke methylated na hydroxypropylated cellulose ether, nke usoro ihe omimi ya nwere otu hydroxyl n'ime molekul cellulose nke methoxy na hydroxypropyl nọchiri anya ya. Ihe “E” dị na ụdị E15 na-anọchi anya ojiji ya bụ isi dị ka onye na-agba ume na stabilizer, ebe “15” na-egosi nkọwapụta viscosity ya.
Ọdịdị
HPMC E15 na-abụkarị ntụ ọcha ma ọ bụ na-acha ọcha na-enweghị isi, enweghị ụtọ na ihe na-adịghị egbu egbu. Akụkụ ya dị mma ma na-agbaze ngwa ngwa n'ime mmiri oyi na mmiri ọkụ iji mepụta ngwọta na-enweghị atụ ma ọ bụ ubé turbid.
Solubility
HPMC E15 nwere ezigbo mmiri solubility ma nwee ike ịgbaze ngwa ngwa na mmiri oyi iji mepụta ngwọta na ụfọdụ viscosity. Ihe ngwọta a na-anọgide na-eguzosi ike na okpomọkụ dị iche iche na ntinye uche na gburugburu ebe obibi adịghị emetụta ya ngwa ngwa.
Viscosity
E15 nwere nnukwu viscosity. Dabere n'iji ya eme ihe, enwere ike nweta viscosity chọrọ site n'ịgbanwe nhazi na ngwọta okpomọkụ. N'ikwu okwu n'ozuzu, E15 nwere viscosity nke ihe dịka 15,000cps na ngwọta 2%, nke na-eme ka ọ rụọ ọrụ nke ọma na ngwa ndị chọrọ nnukwu viscosity.
2. Njirimara arụrụ arụ
Mmetụta siri ike
HPMC E15 bụ a ukwuu ịrụ ọrụ nke ọma thickener na ọtụtụ ebe na-eji dị iche iche mmiri dabeere na usoro. Ọ nwere ike ịbawanye viscosity nke mmiri mmiri n'ụzọ dị ukwuu, na-enye ezigbo thixotropy na nkwusioru, ma si otú ahụ melite udidi na nkwụsi ike nke ngwaahịa ahụ.
Mmetụta nkwụsi ike
E15 nwere ezigbo nkwụsi ike, nke nwere ike igbochi sedimentation na agglomeration nke ụmụ irighiri ihe na usoro a gbasasịrị ma nọgide na-enwe otu usoro. Na usoro emulsified, ọ nwere ike mee ka interface mmanụ-mmiri guzosie ike ma gbochie nkewa nkewa.
Ihe na-emepụta ihe nkiri
HPMC E15 nwere ọmarịcha ihe na-emepụta ihe nkiri ma nwee ike mepụta ihe nkiri siri ike na nke doro anya n'elu ala dị iche iche. Ihe nkiri a nwere ezigbo mgbanwe na adhesion ma jiri ya mee ihe na mkpuchi ọgwụ, ihe mkpuchi nri, na mkpuchi ụlọ.
Ngwongwo na-edozi ahụ
E15 nwere ikike ime mmiri siri ike ma nwee ike iji ya mee ihe dị ka ihe na-edozi ahụ na ihe ịchọ mma na ngwaahịa nlekọta anụ ahụ iji mee ka akpụkpọ ahụ dị nro ma dị nro. N'ụlọ ọrụ nri, a pụkwara iji ya mee ihe dị ka ihe na-eme ka mmiri dị jụụ iji gbasaa ndụ nri.
3. Ngwa ngwa
Ụlọ ọrụ nri
N'ime ụlọ ọrụ nri, a na-ejikarị HPMC E15 eme ihe dị ka ihe na-agba agba, stabilizer na emulsifier. Enwere ike iji ya mepụta ice cream, jelii, sauces na ngwaahịa pasta, wdg, iji meziwanye uto na udidi nke nri na ịgbatị ndụ ya.
Ụlọ ọrụ ọgwụ
A na-eji HPMC E15 eme ihe n'ọtụtụ ebe na nkwadebe ọgwụ na ụlọ ọrụ ọgwụ, ọkachasị dị ka ihe kachasị mkpa maka ntọhapụ na-achịkwa yana mbadamba ntọhapụ. Ọ nwere ike ịchịkwa ọnụego ntọhapụ nke ọgwụ ma melite nkwụsi ike na ịdịte aka nke ịdị irè ọgwụ. Tụkwasị na nke ahụ, a na-ejikwa E15 mee ihe na nkwadebe anya, mmanu mmanu na emulsions, wdg, na-enwe ezigbo biocompatibility na nchekwa.
4. Nchekwa na nchekwa gburugburu ebe obibi
HPMC E15 bụ cellulose na-adịghị egbu egbu na nke na-adịghị akpasu iwe nwere ezigbo bioacompatibility na nchekwa. A na-eji ya eme ihe n'ọtụtụ ebe n'akụkụ nri na ọgwụ na-ezute ụkpụrụ nchekwa dị mkpa yana ụkpụrụ iwu chọrọ. Tụkwasị na nke ahụ, E15 nwere ezigbo biodegradability na ọ gaghị emetọ gburugburu ebe obibi, nke na-egbo mkpa nke ọha mmadụ nke oge a maka akwụkwọ ndụ akwụkwọ ndụ na gburugburu ebe obibi.
Hydroxypropyl methylcellulose E15 abụrụla ihe mgbakwunye dị mkpa na ụlọ ọrụ dị iche iche n'ihi njirimara anụ ahụ na kemịkal pụrụ iche yana ọtụtụ ngwa arụ ọrụ. Ọ nwere ọmarịcha ịgba, nkwụsi ike, imepụta ihe nkiri na ihe na-edozi ahụ ma na-ejikarị ya na nri, ọgwụ, ihe owuwu na ihe ịchọ mma. N'otu oge ahụ, E15 nwere ezigbo nchekwa na nchekwa gburugburu ebe obibi, ọ bụkwa ihe dị mkpa na-acha akwụkwọ ndụ akwụkwọ ndụ na ụlọ ọrụ ọgbara ọhụrụ.
