Usoro mgbasa nke Hydroxypropyl methylcellulose (HPMC):

Mgbe a na-agbakwunye ngwaahịa hydroxypropyl methylcellulose (HPMC) na mmiri, ha ga-agbakọta wee gbazee, mana mgbaze a na-adị ngwa ngwa ma sie ike. Enwere ụzọ mgbasa atọ atụpụtara n'okpuru, ndị ọrụ nwere ike họrọ usoro kachasị adaba dịka ojiji ha siri dị:

1. Usoro mmiri ọkụ: Ebe ọ bụ na hydroxypropyl methylcellulose (HPMC) adịghị agbaze n'ime mmiri ọkụ, a pụrụ ịgbasa mmalite nke hydroxypropyl methylcellulose (HPMC) na mmiri ọkụ, mgbe ahụ, mgbe ọ dị jụụ, a na-akọwa usoro atọ A na-ahụkarị. so:

1). Tinye mmiri ọkụ achọrọ n'ime akpa ahụ wee kpoo ya ihe dịka 70 Celsius. Nke nta nke nta tinye hydroxypropyl methylcellulose (HPMC) n'okpuru nwayọọ edemede, na hydroxypropyl methylcellulose (HPMC) na-amalite sere n'elu n'elu mmiri, wee jiri nwayọọ nwayọọ na-etolite a slurry, jụụ slurry n'okpuru edemede .

2). Kpoo 1/3 ma ọ bụ 2/3 (ego achọrọ) nke mmiri n'ime akpa wee kpoo ya ruo 70 Celsius. Dị ka usoro nke 1 si dị, gbasaa hydroxypropyl methylcellulose (HPMC) iji kwadebe slurry mmiri ọkụ; Mgbe ahụ, tinye ihe fọdụrụ nke mmiri oyi ma ọ bụ mmiri ice n'ime akpa ahụ, tinyezie hydroxypropyl methylcellulose (HPMC) nke a kpọtụrụ aha n'elu na mmiri oyi, ma kpalie, wee kpoo ngwakọta ahụ.

3). Tinye 1/3 ma ọ bụ 2/3 nke mmiri achọrọ n'ime akpa wee kpoo ya ruo 70 Celsius. Dị ka usoro nke 1 si dị, gbasasịa hydroxypropyl methylcellulose (HPMC) iji kwadebe slurry mmiri ọkụ; A na-agbakwunye ihe fọdụrụ nke mmiri oyi ma ọ bụ ice mmiri na mmiri ọkụ na-ekpo ọkụ ma mee ka ngwakọta ahụ dị jụụ mgbe ọ kpalitere.

2. Usoro ngwakọta ntụ ntụ: hydroxypropyl methylcellulose (HPMC) ntụ ntụ na nha nha ma ọ bụ karịa nke ihe ndị ọzọ na-emepụta ntụ ntụ na-agbasasị n'ụzọ zuru ezu site na ngwakọta akọrọ, wee gbazee na mmiri, mgbe ahụ, hydroxypropyl methylcellulose Base cellulose (HPMC) nwere ike gbazee na-enweghị agglomeration. . 3. Organic mgbaze wetting usoro: tupu-achụsasịa ma ọ bụ mmiri hydroxypropyl methylcellulose (HPMC) na organic solvents dị ka ethanol, ethylene glycol ma ọ bụ mmanụ, na mgbe igbari ya na mmiri. N'oge a, hydroxypropyl methylcellulose (HPMC) nwekwara ike agbaze nke ọma.
