Hydroxypylththththththylcelllose (hpmc)bụ nke na-abụghị nke Ionic sel cellulose nke eji eme ihe, ọgwụ, nri, ihe nri, ihe ịchọ mma na mpaghara ụlọ ọrụ ndị ọzọ. O nwere ọtụtụ ihe anụ ahụ kachasị mma, nke na-eme ka ọ rụọ ọrụ nke ọma na ngwa dị iche iche.
1. Ọdịdị na solubality
HPMC na-abụkarị nke na-acha ọcha ma ọ bụ nke na-acha ọcha, enweghị isi, keenweghi ụma na enweghị ihe na-egbu egbu. Enwere ike ịgbasa ya na mmiri oyi na ụfọdụ sonvic sochiri anya (dị ka sọftụ a gwakọtara agwakọta dị ka ethanol / mmiri na acetone / mmiri na-enweghị atụ, ether na chloroform. N'ihi ọdịdị ya na-abụghị nke ionic, ọ gaghị emeghachi omume electrolytic na ngwọta a ma ọ gaghị emetụta ya site na ph uru.
2. Viscosis na rhiology
Ngwọta osisi HPMC nwere ezigbo ihe na-atọ ụtọ na ThixOtropy. Ofdị nchegharị dị iche iche nwere viscosities dị iche iche, yana usoro a na-ahụkarị bụ 5 ruo 100000, 20 ° C). Ngwọta ya gosipụtara pseudoplastity, ya bụ, shiee thinning peterman, ma dịkwa mma maka ngwa mkpuchi, slurries, wdg chọrọ rhiology.
3.
Mgbe HPMC kpo oku na mmiri, nghọta nke ihe ngwọta na-ebelata na gel. Mgbe obi jụrụ, steeti Gel ga-alaghachi na steeti a ga - esi. Ofdị hpmc dị iche iche nwere okpomọkụ dị iche iche, n'ozuzu n'etiti 50 na 75 Celsius. Ngwongwo a dị ezigbo mkpa na ngwa ndị dị ka nke ụlọ ọgwụ na okpu ọgwụ.
4.
N'ihi na HPMC Molecules nwere hydrophilic otu na hydrophobic otu, ha na-egosi ụfọdụ ọrụ dị elu ma nwee ike igwu egwu, ndị na-agbasa ma na-eme mkpọtụ. Dịka ọmụmaatụ, na mkpuchi na emulsions, hpmc nwere ike ime ka nkwụsi ike nke emulsion ma gbochie nkọcha nke ụmụ irighiri ihe.
5. Hygroscopity
HPMC nwere ụfọdụ hygroscopity ma nwee ike ịnwe mmiri na gburugburu iru mmiri. Ya mere, na ụfọdụ ngwa, a ga-akwụrịrị nlebara anya ka nkwakọ ngwaahịa iji gbochie mkpoju mmiri na agglomeration.
6. Ihe onwunwe na-eme ihe nkiri
HPMC nwere ike itolite ihe nkiri siri ike ma sie ike, nke a na-ejikarị nri, ọgwụ (dịka ndị na-ese ihe) na coilings. Dịka ọmụmaatụ, na ụlọ ọrụ ọgwụ, enwere ike iji ihe nkiri HPMC dị ka usoro mkpuchi mbadamba iji meziwanye nkwụsi ike na ntọhapụ nchịkwa.
7. Biocom na nchekwa
HPMC bụ ihe na-adịghị egbu egbu na ihe na-adịghị emerụ ahụ, enwere ike ịbụ ahụ ahụ mmadụ dị iche, yabụ na-eji ya n'ọtụtụ ọgwụ na nri. Dị ka ọgwụ na-emepụta ọgwụ, a na-ejikarị ya emepụta mbadamba akwụkwọ, capsule, wdg.
8. Ike nke Ngwọta
HPMC kwụsiri ike na pọpụ nke 3 ruo 11, ma enwere ike iji acid na Alkali, dị ka ngwaahịa dị iche iche, ngwaahịa kemịkal kwa ụbọchị na usoro kemịkalụ.
9.. Ntughari nnu
Ngwọta HPMC dịtụsi ike na nnu nnu na-adịghị mfe ma ọ bụ na-enweghị arụ ọrụ n'ihi mgbanwe na sistemụ nwere sistemụ nke nnu (dịka okwute cent).
10. Ike nke ikuku
Nchekwa nwere ezigbo nkwụsi ike na gburugburu okpomọkụ dị elu, mana ọ nwere ike mebie ma ọ bụ discolor mgbe ekpughere okpomọkụ ogologo oge. Ọ ka nwere ike ịnọgide na-arụ ọrụ dị mma n'ime ụfọdụ okpomọkụ (na-abụkarị n'okpuru 200 Celsius C), yabụ ọ dabara maka ngwa nhazi nhazi dị elu.
11. Ike kemịkalụ
HpmcỌ dịtụ mma na ọkụ, ọ bụ kemịkal na mmiri ọgwụ nkịtị, site na ihe ndị na-emepụta kemịkalụ dị mfe. Ya mere, enwere ike iji ya na ngwaahịa chọrọ nchekwa ogologo oge, dịka ụlọ na ọgwụ.
A na-eji hydroxypyl methylcelllose na ọtụtụ ụlọ ọrụ n'ihi sọsọ ụkwụ ya, ndị na-eme ihe nkiri, ihe nkiri na-akpụ akpụ na nkwụsi ike. N'ime ụlọ ọrụ owuwu, enwere ike iji ya mee ihe mkpuchi ciment; N'ime ụlọ ọrụ ọgwụ, enwere ike iji ya dị ka ọgwụ na-emepụta ọgwụ; N'ime ụlọ ọrụ nri, ọ bụ ihe mgbakwunye nri. Ọ bụ ihe ndị a pụrụ iche ndị na-eme HPMC ihe dị mkpa polymer arụ ọrụ.
