Hydroxypropyl methylcellulose (HPMC) bụ ihe dị mkpa nke nwere ọtụtụ ngwa ngwa na ụlọ ọrụ ọgwụ yana ụlọ ọrụ ndị ọzọ dị ka nri, ihe ịchọ mma na ihe owuwu.Ọchịchọ maka HPMC na-etowanye nke ọma kemgbe ọtụtụ afọ n'ihi ihe ndị pụrụ iche dị ka ịgbakọ, njide, imepụta ihe nkiri na njide mmiri.N'isiokwu a, anyị ga-atụle usoro mmepụta nke alkaline leaching hydroxypropyl methylcellulose (HPMC).
Usoro mmepụta nke alkali leaching hydroxypropyl methylcellulose (HPMC) bụ usoro nke cellulose na-emeghachi omume na propylene oxide na methyl chloride n'ihu alkali.Usoro a na-ewere ọnọdụ n'okpuru ọnọdụ okpomọkụ, nrụgide na oge a na-achịkwa iji mepụta ngwaahịa HPMC dị elu.
Nzọụkwụ mbụ n'imepụta HPMC site na iji usoro mmepụta alkaline leaching bụ nkwadebe nke akụrụngwa cellulose.A na-ebu ụzọ mee ka cellulose dị ọcha site n'iwepụ ihe ọ bụla adịghị ọcha wee ghọọ alkali cellulose site na ọgwụgwọ na alkali dị ka sodium hydroxide.Nzọụkwụ a dị oke egwu n'ihi na ọ na-abawanye mmeghachi omume nke cellulose na reagents ejiri mee ihe na usoro ndị ọzọ.
A na-emeso Alkali cellulose na ngwakọta nke propylene oxide na methyl chloride n'okpuru okpomọkụ na nrụgide na-achịkwa.Mmeghachi omume n'etiti cellulose alkali na reagent na-arụpụta nguzobe nke ngwaahịa, nke bụ ngwakọta nke hydroxypropyl methylcellulose na ngwaahịa ndị ọzọ.

Usoro mmepụta nke alkali leaching hydroxypropyl methylcellulose (HPMC) nwere ọtụtụ uru ma e jiri ya tụnyere ụzọ mmepụta ndị ọzọ dị ka etherification.Otu n'ime uru ya bụ na ọ bụ usoro na-emetụta gburugburu ebe obibi.N'adịghị ka usoro ndị ọzọ, usoro mmepụta nke alkali leaching adịghị eji ihe mgbaze halogenated na-emerụ ahụ na gburugburu ebe obibi na ahụike mmadụ.
Uru ọzọ nke usoro a bụ mmepụta nke ngwaahịa HPMC dị ọcha.Ọnọdụ mmeghachi omume a na-achịkwa na-ahụ na ngwaahịa ikpeazụ na-agbanwe agbanwe ma dabara adaba maka ngwa dị iche iche.
Ojiji nke HPMC na ụlọ ọrụ ọgwụ dị oke mkpa maka mmepụta nke mbadamba nkume, capsules na ụdị usoro ọgwụgwọ ndị ọzọ.Enwere ike iji HPMC mee ihe dị ka onye na-ekekọta, disintegrant, mkpuchi mkpuchi, wdg. Iji HPMC na ngwa ndị a na-eme ka a hụ na ụdị usoro ọgwụgwọ dị elu ma na-emezu ụkpụrụ achọrọ.
A na-ejikwa HPMC mee ihe dị ka thickener, emulsifier na stabilizer na ụlọ ọrụ nri.Ojiji nke HPMC na ngwaahịa nri na-eme ka udidi, viscosity na ịdị mma na-agbanwe agbanwe.
N'ime ụlọ ọrụ ihe owuwu, a na-eji HPMC mee ihe dị ka ihe mgbakwunye ciment iji meziwanye arụmọrụ, njigide mmiri na njide nke ciment.Ojiji nke HPMC na-eme ka a mata na ngwaahịa ihe owuwu dị elu ma mezuo ụkpụrụ achọrọ.
Na nchịkọta, usoro mmepụta nke alkali leaching hydroxypropyl methylcellulose (HPMC) bụ usoro maka ịmepụta ngwaahịa HPMC dị elu ma na-ejikarị eme ihe na ụlọ ọrụ dị iche iche dị ka ọgwụ, nri, na ihe owuwu.Iji HPMC na ngwa ndị a na-eme ka a mara na ngwaahịa ahụ dị oke mma ma na-emezu ụkpụrụ achọrọ.Usoro mmepụta a dịkwa mma na gburugburu ebe obibi ma na-emepụta ngwaahịa HPMC dị ọcha.
