Uburyo bwo gushonga hamwe ningamba ya HPMC

HydroxyPropyl methylcellse ni hafi idahujwe na ethanol yuzuye na acetone. Igisubizo cyamazi ni gihamye cyane mubushyuhe bwicyumba kandi gishobora gufata ubushyuhe bwinshi. Ibyinshi muri hydroxyproppopyl methylcellse kumasoko noneho ni iy'amazi akonje (amazi yubushyuhe, amazi meza) ubwoko bwihuse. Amazi akonje ako kanya Hpmc izaba nziza cyane kandi itekanye gukoresha. HPMC ikeneye kongerwaho mu buryo butaziguye igisubizo gikonje nyuma yiminota icumi muminota mirongo mirongo cyenda kugirango bibyimbye buhoro buhoro. Niba ari icyitegererezo kidasanzwe, kigomba gukangurwa n'amazi ashyushye yo gutatana, hanyuma asuka mumazi akonje kugirango ashonge nyuma yo gukonja.

Iyo ibicuruzwa bya HPMC byongewe mumazi, bazatera ubwoba hanyuma barashonga, ariko iyi myandaro iratinda cyane kandi iragoye. Uburyo butatu bukurikira bukurikira, kandi abakoresha barashobora guhitamo uburyo bworoshye ukurikije uko ibintu byoroshye gukoreshwa (cyane cyane kumazi akonje ako kanya hpmc).

Uburyo bwo gushonga hamwe ningamba ya HPMC

1. Uburyo bw'amazi bukonje: mugihe ikeneye kongerwaho ubushyuhe busanzwe igisubizo gisanzwe, nibyiza gukoresha ubwoko bwubukonje bukonje. Nyuma yo kongeramo visosity, guhuza bizagenda byiyongera buhoro buhoro ibisabwa.

2. Uburyo bwo kuvanga powder: Ifu ya HPMC hamwe nubunini bumwe cyangwa byinshi mubice byifu byatatanye byuzuye, na nyuma yo kongeramo amazi yo kuvanga, kandi nyuma yo kongeramo amazi yo kuvanga, kandi nyuma yo kongeramo amazi yo kuvanga, kandi nyuma yo kongeramo amazi yo kuvanga, kandi nyuma yo kongeramo amazi yo kuvanga, kandi nyuma yo kongeramo amazi yumye, kandi nyuma yo kongeramo amazi yo kuvanga, kandi nyuma yo kongeramo amazi yo kuvanga, kandi nyuma yo kongeramo amazi yo kuvanga, kandi nyuma yo kongeramo amazi yo kuvanga, kandi nyuma yo kongeramo amazi yo kuvanga, kandi nyuma yo kongeramo amazi yo kuvanga, kandi nyuma yo kongeramo amazi yumye, kandi nyuma yo kongeramo amazi yo kuvanga, kandi nyuma yo kongeramo amazi yo kuvanga, kandi nyuma yo kongeramo amazi yo kuvanga, kandi nyuma yo kongeramo amazi yo kuvanga, kandi nyuma yo kongeramo amazi yumye, kandi amaze gushonga muri iki gihe kandi ntazongera gutera imbere. Mubyukuri, uko byagenda kose ubwoko bwa hydroxypropyl methylcellse. Irashobora kyuma bivanze mubindi bikoresho.

3. Organic Solvent Etting Uburyo: HPMC iratatana cyangwa itose hamwe na ordonac, nka ethanol glycol cyangwa amavuta, kandi noneho irashonga mumazi neza.

Mugihe cyo guturika, niba hari agglomeration, izapfunyika. Nibisubizo byungutse bidafite ishingiro, ni ngombwa rero kwihutisha umuvuduko ushimishije. Niba hari ibituba mu ingwe, biterwa n'umwuka watewe no gukangurira ntanganiye, kandi igisubizo kiremererwa guhagarara ku masaha 2- 12 (igihe cyihariye giterwa no guhuza igisubizo) cyangwa vacumu nubundi buryo Gukuraho, kongeramo amafaranga akwiye nabyo birashobora gukuraho iki kibazo. Ongeraho umubare ukwiye wa defoamer urashobora kandi gukuraho iki kibazo.

Kubera ko hydroxpropyl methylcellse ikoreshwa mu nganda zinyuranye, ifite akamaro kanini ko kumenya uburyo bwo kuvugurura hydroxypropyl methylcellse kugirango ikoreshwe neza. Byongeye kandi, abakoresha bibutswa kwitondera izuba, kurengera imvura no kurengera ubushuhe mugihe cyo gukoresha, irinde umucyo utaziguye, kandi ubike ahantu hashyizweho kashe kandi humye kandi humye. Irinde guhura no gutwika amaso hanyuma wirinde gushiraho umukungugu mwinshi mubidukikije kugirango wirinde ibyago.
