Mgbasa nke HPMC

N'ime ụlọ ọrụ ihe owuwu, a na-etinye HPMC n'ime mmiri na-anọpụ iche, a na-agbazekwa ngwaahịa HPMC naanị iji kpebie ọnụego mgbasa.

Mgbe etinyechara ya na mmiri na-anọpụ iche, ngwaahịa nke na-agbakọta ngwa ngwa na-enweghị mgbasa bụ ngwaahịa na-enweghị ọgwụgwọ elu;mgbe etinyechara ya na mmiri na-anọpụ iche naanị, ngwaahịa nwere ike ịgbasa ma ghara ịgbakọ ọnụ bụ ngwaahịa nwere ọgwụgwọ elu.

Mgbe ngwaahịa HPMC a na-agwọghị na-agbaze naanị, otu akụkụ ya na-agbaze ngwa ngwa ma mepụta ihe nkiri ngwa ngwa, nke na-eme ka mmiri ghara ịbanye n'ime ihe ndị ọzọ, na-ebute agglomeration na agglomeration.A na-akpọ ya ngwa ngwa ngwaahịa na ahịa ugbu a.Ihe e ji mara HPMC a na-agwọghị bụ: ihe ndị dị n'otu n'otu na-agbaze ngwa ngwa na steeti na-anọpụ iche, alkaline na acidic, mana enweghị ike ịgbasa n'etiti ihe ndị dị na mmiri mmiri, na-ebute agglomeration na nchịkọta.Na arụ ọrụ n'ezie, mgbe mgbasa anụ ahụ nke usoro ngwaahịa a na ihe siri ike dị ka ntụ ntụ roba, ciment, ájá, wdg, ọnụego mgbasa dị ngwa ngwa, ọ dịghịkwa agglomeration ma ọ bụ agglomeration.Mgbe ọ dị mkpa igbari ngwaahịa HPMC dị iche iche, a ga-eji nlezianya mee usoro ngwaahịa a, n'ihi na ọ ga-emewanyewanye ma na-etolite lumps.Ọ bụrụ na ọ dị mkpa igbari ngwaahịa HPMC na-adịghị edozi iche, ọ ga-adị mkpa ka a chụsa ya n'otu n'otu na mmiri ọkụ 95ºC, wee mee ka ọ dị jụụ ka ọ gbazee.

Ngwakọta ngwaahịa HPMC na-emeso ihu, na mmiri na-anọpụ iche, enwere ike ịgbasa ihe irighiri ihe ọ bụla na-enweghị agglomeration, mana agaghị emepụta viscosity ozugbo.Mgbe ịsachara ruo oge ụfọdụ, a na-ebibi usoro kemịkalụ nke ọgwụgwọ elu, na mmiri nwere ike igbari ihe ndị HPMC.N'oge a, a na-achụsasị ngwaahịa ahụ n'ụzọ zuru ezu ma tinye ya na mmiri zuru oke, ya mere ngwaahịa ahụ agaghị emegharị ma ọ bụ agglomerate mgbe mgbasa.Ọsọ mgbasa na mgbasa ozi na-adabere na ogo ọgwụgwọ elu.Ọ bụrụ na ọgwụgwọ elu dị ntakịrị, ọsọ nke mgbasa ozi na-adị nwayọọ ma na-agbagide ọsọ na-adị ngwa ngwa;mgbe ngwaahịa na miri n'elu ọgwụgwọ nwere ngwa ngwa mgbasa ọsọ na ngwa ngwa na-arapara ọsọ.Ọ bụrụ na ịchọrọ ime ka usoro ngwaahịa a gbazee ngwa ngwa na steeti a, ị nwere ike ịdaba obere ihe alkaline mgbe ha na-agbaze naanị.A na-akpọkarị ahịa ugbu a dị ka ngwaahịa na-agbaze ngwa ngwa.The e ji mara elu-emeso HPMC ngwaahịa bụ: na aqueous ngwọta, na ahụ nwere ike achụsa na onye ọ bụla ọzọ, ike igbari ngwa ngwa na alkaline ala, na igbari nwayọọ nwayọọ na-anọpụ iche na acidic ala.

N'ezie mmepụta ọrụ, a usoro nke ngwaahịa mgbe igbari mgbe na-chụgara ndị ọzọ siri ike urughuru ihe n'okpuru alkaline ọnọdụ, na mgbasa ọnụego adịghị iche na nke untreated ngwaahịa.Ọ dịkwa mma maka iji ngwaahịa na-agbaze naanị, na-enweghị caking ma ọ bụ lumps.Enwere ike ịhọrọ ụdị nke ngwaahịa a kapịrị ọnụ dị ka ọnụego mgbasa nke ihe owuwu ahụ chọrọ.

N'oge usoro ihe owuwu, ma ọ bụ ciment mortar ma ọ bụ gypsum dabeere na slurry, ọtụtụ n'ime ha bụ usoro alkaline, na ego nke HPMC agbakwunyere dị ntakịrị, nke nwere ike gbasaa n'etiti ihe ndị a.Mgbe agbakwunyere mmiri, HPMC ga-agbaze ngwa ngwa.Naanị ezigbo hydroxypropyl methylcellulose nwere ike iguzogide ule nke oge anọ: a na-achịkwa usoro mmeghachi omume nke ọma iji mepụta HPMC, na nnọchi ya zuru oke na ịdị n'otu dị ezigbo mma.Ngwọta mmiri ya doro anya ma doo anya, yana eriri ole na ole n'efu.Nkwekọrịta na ntụ ntụ roba, ciment, lime na ihe ndị ọzọ bụ isi dị ike karịsịa, nke nwere ike ime ka isi ihe na-arụ ọrụ kacha mma.Agbanyeghị, HPMC nwere mmeghachi omume na-adịghị mma nwere ọtụtụ eriri n'efu, nkesa na-ezighi ezi nke ihe mgbakwunye, njigide mmiri na-adịghị mma na ihe ndị ọzọ, na-ebute oke ikuku mmiri na ihu igwe dị elu.Otú ọ dị, ihe a na-akpọ HPMC nwere nnukwu ihe mgbakwunye na-esiri ike ịhazi onwe ya, ya mere arụmọrụ nke njide mmiri ka njọ.Mgbe a na-eji HPMC na-adịghị mma, a ga-ebute nsogbu ndị dị ka obere slurry ike, obere oge oghere, ntụ ntụ, mgbawa, oghere na ịkwafu, nke ga-eme ka ihe isi ike na-arụ ọrụ dịkwuo elu ma belata ịdị mma nke ụlọ ahụ.Otu ihe ahụ bụ cellulose ether, nwere ike nweta nsonaazụ dị iche iche.
