Ubusanzwe busanzwe bwa HPMC mubikorwa byubwubatsi
1 Intangiriro
Hydroxypropyl Methylcellulose (HPMC) ni inyongera yibikoresho byubaka kandi ikoreshwa cyane mubicuruzwa bitandukanye mu nganda zubaka ibikoresho, nka minisiteri yumye-ivanze, ifu yuzuye, ifu ya tile, nibindi HPMC ifite imirimo myinshi nko kubyimba, gufata amazi, no kunoza imikorere yubwubatsi. Imikorere yayo iterwa ahanini nubwiza bwayo. Iyi ngingo izasesengura mu buryo burambuye urwego rusange rwa viscosity rwa HPMC mubikorwa bitandukanye byubwubatsi n'ingaruka zabyo mubikorwa byubwubatsi.
2. Ibiranga shingiro bya HPMC
HPMC ni ether-ionic water-soluble selulose ether yabonetse muguhindura imiti ya selile naturel. Ifite ibintu bigaragara bikurikira:
Kubyimba: HPMC irashobora kongera ubwiza bwibikoresho byubwubatsi kandi igatanga imikorere myiza.
Kubika amazi: Irashobora kugabanya neza guhinduka kwamazi no kunoza imikorere ya hydration reaction ya sima na gypsumu.
Amavuta: Bituma ibintu byoroha mugihe cyo kubaka kandi byoroshye kubishyira mubikorwa.
Imiterere yo gukora firime: Filime yakozwe ifite ubukana bwiza kandi ihindagurika kandi irashobora kunoza imiterere yibintu.
3. Gukoresha HPMC mubikoresho byubwubatsi
Gufata amatafari: Uruhare nyamukuru rwa HPMC mugufata tile ni ukunoza imbaraga zo guhuza hamwe nigihe cyo gufungura. Urwego rwijimye ruri hagati ya 20.000 na 60.000 mPa · s kugirango rutange ibintu byiza byo guhuza hamwe nigihe cyo gufungura. Ubukonje bwinshi HPMC ifasha kongera imbaraga zo guhuza tile ifata kandi igabanya kunyerera.
Ifu yuzuye: Mu ifu yuzuye, HPMC igira uruhare runini mu gufata amazi, gusiga no kunoza imikorere. Ubukonje busanzwe buri hagati ya 40.000 na 100.000 mPa · s. Ubukonje buhanitse bufasha kugumana ubushuhe mu ifu ya putty, kunoza igihe cyubwubatsi bwayo no gukora neza.
Kuma ivanze yumye: HPMC ikoreshwa mumashanyarazi yumye kugirango yongere imbaraga zo gufata no gufata amazi. Ubusanzwe ubukonje buri hagati ya 15.000 na 75.000 mPa · s. Muburyo butandukanye bwo gukoresha, guhitamo HPMC hamwe nubwiza bukwiye birashobora guhindura imikorere yo guhuza no kubika amazi ya minisiteri.
Kwiyubaka kwa minisiteri: Kugirango uburinganire bwikigereranyo bugire amazi meza kandi buringaniza, ubwiza bwa HPMC mubusanzwe buri hagati ya 20.000 na 60.000 mPa · s. Uru ruhererekane rw'imitsi rwemeza ko minisiteri ifite amazi ahagije bitagize ingaruka ku mbaraga zayo nyuma yo gukira.
Igikoresho kitarimo amazi: Mu mwenda utagira amazi, ubwiza bwa HPMC bugira uruhare runini ku miterere yo gutwikira no gukora firime. HPMC ifite ubukonje buri hagati ya 10,000 na 50.000 mPa · s ikoreshwa muburyo bwiza bwo gutembera neza no gukora firime.
4. Guhitamo ubwiza bwa HPMC
Guhitamo ibishishwa bya HPMC ahanini biterwa nuruhare rwayo mubikorwa byihariye nibisabwa byubaka. Mubisanzwe, uko ubukonje bwa HPMC buri hejuru, niko bigenda byiyongera kandi bikagumana amazi, ariko cyane cyane ubukonje bushobora gutera ingorane zo kubaka. Kubwibyo, guhitamo HPMC hamwe nubwiza bukwiye nurufunguzo rwo kwemeza ibisubizo byubwubatsi.
Ingaruka yibyibushye: HPMC ifite ubukonje bwinshi ifite imbaraga zo kubyimba kandi irakwiriye kubisabwa bisaba gufatana cyane, nka kile ya tile na poro.
Imikorere yo gufata amazi: HPMC ifite ubukonje bwinshi ni byiza cyane mu kugenzura ubushuhe kandi irakwiriye kubikoresho bigomba kugumana ubushuhe igihe kirekire, nka minisiteri yumye.
Igikorwa: Kugirango tunoze imikorere yibikoresho, ubukonje buringaniye bufasha kunoza imikorere yibikorwa byubwubatsi, cyane cyane muri minisiteri yo kwishyiriraho.
5. Ibintu bigira ingaruka kuri HPMC
Impamyabumenyi ya polymerisiyasi: Iyo urwego rwo hejuru rwa polymerisation ya HPMC, niko rwinshi. Porogaramu zitandukanye zisaba guhitamo HPMC hamwe nimpamyabumenyi zitandukanye za polymerisation kugirango ugere kubisubizo byiza.
Kwibanda kumuti: Kwibanda kwa HPMC mumazi nabyo bizagira ingaruka kubwiza bwayo. Muri rusange, uko igisubizo cyibanze cyane, niko ubwiza bwiyongera.
Ubushyuhe: Ubushyuhe bugira ingaruka zikomeye ku bwiza bwibisubizo bya HPMC. Mubisanzwe, ubwiza bwibisubizo bya HPMC buragabanuka uko ubushyuhe bwiyongera.
Ninyongera yingenzi mubikoresho byubwubatsi, ubwiza bwa HPMC bugira ingaruka cyane mubikorwa byubwubatsi no gukoresha ingaruka zibicuruzwa byanyuma. Urwego rwa viscosity rwa HPMC ruratandukanye hagati ya porogaramu, ariko mubisanzwe ni hagati ya 10,000 na 100.000 mPa · s. Mugihe uhisemo HPMC ibereye, birakenewe ko dusuzuma byimazeyo ingaruka ziterwa nubukonje kumitungo ukurikije ibisabwa byihariye nibisabwa kugirango ubwubatsi bugerweho.
