Ireme ryaHydroxyPropyl Methylcellse (HPMC)irashobora gusuzumwa binyuze mubipimo byinshi. HPMC ni ugusiga ka churituwe bikoreshwa cyane mubwubatsi, imiti, inganda zibihingwa, inganda ziroroshye, hamwe nibyiza bigira ingaruka muburyo bwibicuruzwa.
1. Kugaragara nubunini
Kugaragara kwa HPMC bigomba kuba ifu ya Amorhous yera cyangwa yera. Ifu yuzuye ya HPMC igomba kugira ibice bimwe, nta gugglomera, kandi nta mbanire zamahanga. Ingano n'ibirindiro by'ibice bigira ingaruka ku buke bwo kwikeba no kudacogora. HPMC hamwe nibice binini cyangwa bikabije bitagira ingaruka gusa gusa, ahubwo birashobora kandi gutera ingaruka zitagabanuka zitaringaniye muburyo bwa porogaramu. Kubwibyo, ingano imwe ni ishingiro ryo gusuzuma ireme ryayo.
2. AMAZI YO KUBUNTU N'UMUNTU
Amazi yoroshye ya HPMC nimwe mubipimo byingenzi byingenzi. Isuku yo hejuru HPMC irashonga vuba mumazi, kandi igisubizo cyaciwe kigomba kuba umucyo kandi cyambaye imyenda. Ikizamini cyo kwishyurwa no kongeraho mu kongera umubare wa HPMC ku mazi no kwitegereza niba bishobora gushonga vuba kandi bigize igisubizo gihamye. Gusetsa gahoro cyangwa igisubizo kidafite ishingiro birashobora gusobanura ko ibicuruzwa bitujuje ubuziranenge.
3. Ibiranga vino
Uruzinduko rwa HPMC nimwe mubipimo byingenzi byo gusuzuma ubuziranenge. Ubukwe bwayo mumazi mubisanzwe bwiyongera hamwe no kwiyongera k'uburemere bwa molekile. Uburyo bwo kwipimisha ibizamini ni ugukoresha amashusho ya robitwari cyangwa vicometer kugirango apime indangagaciro zikibazo cyibisubizo bitandukanye. Muri rusange, uburyo bwo hejuru bwa HPMC bugomba kuba vicositine ihamye, kandi ihinduka rya scosity hamwe no kongera kwibanda bigomba guhuza n'amategeko runaka. Niba uruzitiro rudahungabana cyangwa munsi yurwego rusanzwe, birashobora gusobanura ko imiterere yacyo idahungabana cyangwa ikubiyemo umwanda.
4. Ibirimo
Ubushuhe muri HPMC nabyo bizagira ingaruka ku bwiza. Ubushuhe bukabije bushobora gutuma bugabanuka cyangwa kwangirika mugihe cyo kubika. Ibipimo byibirimo byihuta bigomba kugenzurwa muri 5%. Uburyo bwikizamini nkuburyo bwumye cyangwa uburyo bwa karl burashobora gukoreshwa kugirango hamenyekane ibintu byubushuhe. Isuku yo mu rwego rwo hejuru HPMC ifite ibintu byinshi kandi igakomeza kumema kandi ihamye.
5. PH agaciro k'igisubizo
Agaciro PH gakemuke ka HPMC karashobora kandi kwerekana ubuziranenge bwayo. Mubisanzwe, agaciro ka PH gakwiye gukemura HPMC bigomba kuba hagati ya 6.5 na 8.5. Accidic cyane cyangwa ibisubizo bya alkaline birashobora kwerekana ko ibicuruzwa birimo ibice bya shimi cyangwa byavuwe nabi mugihe cyo kubyara. Binyuze muri PH Kwigerageza, urashobora kumva neza niba ubwiza bwa HPMC bujuje ibisabwa.
6.
Ibikubiye muri HPMC bigira ingaruka kubikorwa byayo, cyane cyane mumwanya wubuvuzi nibiryo, aho ibintu bitujuje ibyangombwa bishobora gutera ibicuruzwa bidafite umutekano cyangwa ingaruka mbi. Ubusanzwe umwanda zirimo ibikoresho bibisi byakozwe neza, ibindi biti, cyangwa umwanda byabyaye mugihe cyo kubyara. Ibihuru byanduye muri HPMC birashobora kugaragara nuburyo nkibikorwa byinshi byamazi ya chromatografiya (HPLC) cyangwa chromatografiya (GC). Kurenza urugero HPMC igomba kwemeza imyanzuro mike kandi yujuje ubuziranenge.
7. Gukorera mu mucyo no gukemura igisubizo
Gufata ibicuruzwa bya HPMC nabyo ni ikimenyetso gikunze gukoreshwa. Igisubizo hamwe no gukorera mu mucyo Mugari no gutuza mubisanzwe bivuze ko HPMC ikunganiye cyane kandi ifite umwanda nke. Igisubizo kigomba kuguma gisobanutse kandi kibonerana mugihe cyo kubika igihe kirekire, nta mvura cyangwa uhindagurika. Niba igisubizo cya HPMC cyatoranijwe cyangwa kiba kuri kavukire mugihe cyo kubika, byerekana ko ishobora kubamo ibice bidatinze cyangwa umwanda.
8. Ubushyuhe bwa Trarmal hamwe nubushyuhe bwo kubora ubushyuhe
Ikizamini cyumutekano cyubushyuhe kirimo gukorwa nisesengura rya TherMogravimecc (Tga). HPMC igomba kugira umutekano mwiza kandi idakwiye kubora mubushyuhe busanzwe bwo gusaba. HPMC hamwe nubushyuhe buke bwo kubora buzahura na produpation yimikorere yubushyuhe bwinshi, bityo umutekano mwiza cyane ni ikintu gikomeye cyimiterere ya HPMC yo hejuru.
9. Igisubizo cyo gukemura no guhagarika umutima
Impagarara z'ubuso bw'ibisubizo bya HPMC birashobora kugira ingaruka ku mikorere yacyo, cyane cyane mu bice no kubaka ibikoresho. Isuku yo murwego rwohejuru HPMC ifite impagarara zo hasi nyuma yo gusesa, bifasha kunoza amazi n'amazi mubitangazamakuru bitandukanye. Ubuso bwayo burashobora kugeragezwa na metero yubuso. Igisubizo cyiza cya HPMC kigomba kugira impagarara zo hasi kandi zihamye.
10. Guhagarara no kubika
Ububiko bwububiko bwa HPMC burashobora kandi kwerekana ubuziranenge bwabwo. Ubwiza-bwiza HPMC igomba gushobora kubikwa muburyo burebure ntangurizwa cyangwa kwangirika kw'imikorere. Mugihe ukora ubugenzuzi bwiza, umutekano wacyo ushobora gusuzumwa no kubika ingero ndende kandi ugerageze gukora buri gihe. Cyane cyane mubidukikije hamwe nubushuhe bukabije cyangwa ubushyuhe bunini bwanduye, uburyo bwiza bwa HPMC igomba gushobora gukomeza gukomeza umubiri nudushiha.
11. Kugereranya ibisubizo byubushakashatsi nibipimo ngenderwaho
Hanyuma, bumwe mu buryo buteye ubwoba bwo kumenya ubwiza bwa HPMC nukugereranya nibipimo ngenderwaho. Ukurikije umurima usaba (nko kubaka, kuvura, ibiryo, nibindi), ibipimo byiza bya HPMC biratandukanye. Mugihe uhisemo HPMC, urashobora kwerekeza ku bipimo ngenderwaho hamwe nuburyo bwo kwipimisha hanyuma uhure ibisubizo byubushakashatsi kugirango ucire urubanza ubuziranenge bwayo.
Isuzuma ryiza ryaHpmcUkeneye gusuzuma ibintu byinshi, harimo isura, kwikuramo, victcosity, ibikubiyemo, agaciro ka PH kanini, ubuziranenge bwa HPMC burashobora gucirwa urubanza. Kubikenewe mubipimo bitandukanye, ibipimo bimwe byihariye bigomba kandi kwishyurwa. Guhitamo ibicuruzwa bya HPMC byujuje ubuziranenge bushobora kwemeza ubuziranenge no gutuza kubicuruzwa byanyuma.
