Ihe na-emetụta ndụ shelf nke hpmc

Hydroxypylthylthylcelllose (HPMC) bụ ihe eji eme ihe kemịkal akpọrọ nke ọma na ọgwụ, nri, ịchọ mma na ihe owuwu. Ndụ shelf na-ezo aka n'ogologo oge ọ nwere ike idobe ya na akụrụngwa ya n'okpuru ọnọdụ akọwapụtara. Ihe na - emetụta ndụ shelf nke Hpmc gụnyere ọnọdụ gburugburu ebe obibi, ọnọdụ nchekwa, nkwụsi ike kemịkalụ, wdg.

1. Ọnọdụ gburugburu ebe obibi
1.1 okpomọkụ
Ọnọdụ okpomọkụ bụ otu n'ime ihe dị mkpa na-emetụta ndụ shelf nke Hpmc. Ọnọdụ okpomọkụ ga-eme ka mmeghachi omume nke HPMC, na-ebute mgbanwe na akụrụngwa anụ ahụ ya na kemịkal ya. Dịka ọmụmaatụ, HPMC nwere ike ịgbanye odo ma belata viscosity na oke okpomọkụ, na-emetụta arụmọrụ ya. Ya mere, a na-echekwa okpomọkụ nke HPMC na ọnọdụ dị ala, nke dị n'okpuru ala karịa 25 Celsius C, ịgbatị ndụ nchekwa ya.

Iru mmiri 1.2
Mmetụta iru mmiri na hpmc dị oke mkpa. HPMC bụ ihe poymeric polymeric nke na-adị mfe mmiri. Ọ bụrụ na iru mmiri dị na ebe nchekwa dị elu, hpmc ga-enwe mmiri na ikuku, na-eme ka ọhụụ na-agbanwe, na akụkụ ya ga-adị. Ya mere, ekwesịrị idobe Hpmc mgbe echekwara ya, a na-atụ aro ka a na-atụ aro ka a na-achịkwa iru mmiri dị n'okpuru 30%.

2. Ọnọdụ Nchekwa
Windo 2.1
Ihe ngwugwu na akara nwere mmetụta dị na shelf ndụ nke Hpmc. Ngwa ngwugwu dị elu nwere ike ịtọpụ ikuku na mmiri ma gbochie HPMC iji nweta mmiri ma na-emebi. Ngwakọta nkwakọ ngwaahịa a na-ejikarị gụnyere akpa aluminom, akpa polyethylene, wdg, nke nwere ezigbo ihe mgbochi ihe mgbochi. N'otu oge, nkwakọ ngwaahịa a kara aka nwere ike belata kọntaktị nke HPMC na gburugburu ebe obibi ma gbatị ndụ ya.

2.2 ọkụ
Ìhè, karịsịa ultraviolet irrodition, nwere ike ibute mmebi foto nke Hpmc ma metụta akụrụngwa anụ ahụ na kemịkal ya. Mgbe ekpughere ya ọkụ ogologo oge, HPMC nwere ike igbanwe agba agba, wdg. Ya mere, ekwesịrị ịchekwa HPMC na gburugburu - na-eji ihe ngwugwu.

3. Ike kemịkalụ
3.1 Uru
Nkwụsi ike nke HPMC a na-emetụta ya nke ọma. N'okpuru ọnọdụ acidic ma ọ bụ alkaline, Hpmc ga-enwe hydrolysis ma ọ bụ mmeghachi omume, na-eduga na nsogbu dị ka mbelata na mgbanwe na-agbanwe agbanwe. Iji hụ na nkwụsi ike nke HPMC, a na-atụ aro ka a chịkwaa uru nke ihe ngwọta ya na nnọpụiche (PH 6-8).

3.2 adịghị ọcha
Ọnụnọ nke adịghị arụ ọrụ na-emetụta nkwụsi ike nke HPMC. Iji maa atụ, adịghị ọcha dịka eyịm eyịm nwere ike ịnwale mmeghachi omume nke HPMC, na-ebelata shelf ndụ shelf. Ya mere, ekwesiri ịchịkwa ọdịnaya adịghị ọcha n'oge usoro ọgwụgwọ na ịdị ọcha akụrụngwa kwesịrị iji hụ na ịdị ọcha nke HPMC.

4. Mpempe ngwaahịa
Formsdị ngwaahịa HPMC na-emetụtakwa ndụ nchekwa ya. HPMC na-adịkarị n'ụdị ntụ ntụ ma ọ bụ granules. Mmetụta ụdị dị iche iche na ndụ shelf bụ ndị a:

4.1 Mpempe ntụ
HPMC ụdị ntụ ntụ nwere nnukwu mpaghara a kapịrị ọnụ nke dị mfe na-emetọ ya ngwa ngwa, yabụ ndụ shelf ya dị mkpụmkpụ. Ka ịgbatị shelf Life nke powd hpmc, a na-etinye nkwakọ ngwaahịa a ga-eme ka ike gwụsịa iji zere ịkpọtụrụ ikuku na mmiri.

4.2 morthology
Na hpmc irighiri ihe nwere obere mpaghara a kapịrị ọnụ, na-enwekarị hygroscopic, ma nwee ndụ shelf ogologo. Agbanyeghị, HPMC granulated nwere ike iwepụta ájá n'oge nchekwa na ụgbọ njem, na-ebute na ebe nchekwa dị mkpụmkpụ. Ya mere, HPMC HPMC na-achọkwa ezigbo nkwakọ ngwaahịa na ọnọdụ nchekwa.

5. Jiri ihe mgbakwunye
Iji meziwanye nkwụsi ike ma gbasaa ndụ nchekwa nke Hpmc, enwere ike ịgbakwunye ma ọ bụ ihe eji eme ihe na usoro mmepụta. Dịka ọmụmaatụ, ịgbakwunye antioxidants nwere ike igbochi mmebi nke hpmc, ma na-agbakwunye ndị ọrụ na-eto mmiri mmiri nwere ike belata hgroscopity nke Hpmc. Agbanyeghị, nhọrọ na usoro ihe mgbakwunye chọrọ mkpali nke siri ike iji hụ na ha anaghị emetụta ihe akụrụngwa na nchekwa nke HPMC.

ỌTSTỌ ndụ nke HPMC nke HPMC na-emetụta ndụ, gụnyere ọnọdụ gburugburu ebe obibi (ọnọdụ nchekwa), na-adịghị ike (plọ ọrụ), ntụtụ, ngụgụ) na iji ihe mgbakwunye. Iji gbasa ndụ nchekwa nke HPMC, a ga-atụle ihe ndị a, a ga-ewere usoro kwesịrị ekwesị maka njikwa. Dịka ọmụmaatụ, nwee ebe nchekwa dị ala na okpomoku a na-echekwa, na-eji nkwakọ ngwaahịa dị elu, ma belata nchịkwa sayensị na nchekwa nke sayensị na arụmọrụ ya na-ekwe nkwa na mpaghara dị iche iche.
