Ụzọ mgbasa nke HPMC gụnyere: usoro mmiri oyi ozugbo na usoro ngwọta ọkụ, usoro ngwakọta ntụ ntụ na usoro wetting organic mgbaze.
A na-emeso ngwọta mmiri oyi nke HPMC na glioxal, nke a na-agbasa ngwa ngwa na mmiri oyi.N'oge a, ọ bụghị ezigbo ngwọta.Ọ bụ ngwọta mgbe viscosity na-abawanye.A naghị agwọta ngwọta na-ekpo ọkụ na glycoxal.Mgbe olu glycoxal buru ibu, ọ ga-agbasa ngwa ngwa, mana viscosity ga-eji nwayọọ nwayọọ bilie.
Ebe ọ bụ na HPMC enweghị ike ịsacha na mmiri ọkụ, HPMC nwere ike gbasasịa na mmiri ọkụ na mbido mbụ, wee gbazee ngwa ngwa mgbe ọ dị jụụ.
A na-akọwa usoro abụọ ahụkarị n'okpuru:
1) Tinye mmiri ọkụ achọrọ n'ime akpa ahụ ma kpoo ya ihe dịka 70 ℃.Hydroxypropyl methylcellulose e ji nwayọọ nwayọọ gbakwunyere n'okpuru nwayọọ edemede, HPMC malitere ise n'elu mmiri, na mgbe ahụ nke nta nke nta kpụrụ slurry, nke na mma n'okpuru edemede.
2) Tinye 1/3 ma ọ bụ 2/3 nke mmiri achọrọ n'ime akpa ahụ, kpoo ọkụ ruo 70 ℃, gbasaa HPMC dị ka usoro nke 1) iji kwadebe slurry mmiri ọkụ;Mgbe ahụ, tinye nke fọdụrụ mmiri oyi na mmiri ọkụ slurry, nwuo na jụụ ngwakọta.
Enwere ike ịgbaze mmiri oyi ozugbo HPMC site na ịgbakwunye mmiri ozugbo, mana oge viscosity mbụ bụ nkeji 1 ruo 15.Oge ọrụ agaghị agafe oge mmalite.
Usoro ngwakọta ntụ ntụ: HPMC ntụ ntụ na-agbasasị kpamkpam site na ngwakọta akọrọ na otu ma ọ bụ karịa ntụ ntụ, wee gbazee na mmiri.Na nke a, HPMC nwere ike igbari na-enweghị caking.
Usoro wetting organic mgbaze:
Enwere ike ịgbaze Hydroxypropyl methylcellulose site n'ịgbasa ya n'ime ihe mgbaze organic ma ọ bụ wesa ya na ihe mgbaze organic, wee tinye ya na mmiri oyi ma ọ bụ mmiri oyi.Ethanol, ethylene glycol, wdg nwere ike iji dị ka ihe mgbaze organic.
