Ni ubuhe buryo bwa hydroxyproppopyl methylcellse?

HydroxyPropyl methylcellse (HPMC) ni umubyimba, ugent agent na firime byahoze bikoreshwa muri faruceti, ibiryo bitera kwisiga no kubaka. Uburakari bwayo ni kimwe mubipimo byingenzi bigira ingaruka kumikorere yacyo, mubisanzwe biratandukanye ukurikije ibintu nkibisubizo, ubwoko bwikibazo, ubushyuhe nuburemere bwa HPMC.

Agaciro ka Scosity ka HPMC bivuga amazi yumusubizo byacyo mubihe bimwe, ubusanzwe bigaragara muri Mpa · s (milipascal amasegonda). Muri vinosity Standard Standards ya HPMC, kwibanda kuri 2% ni 2% cyangwa 4%, kandi ubushyuhe buke muri rusange 20 ° C cyangwa 25 ° c. Ukurikije ikirango n'ibicuruzwa, viscozetity ya HPMC irashobora kuva kuri magana ya Mapa- ku bihumbi bike MPA · s.

Ibikurikira nimpamvu nyamukuru igira ingaruka kuri viscosity igisubizo cya HPMC:

Uburemere bwa molekilar: nini nini yuburemere bwa HPMC, hejuru ya vicosiya. HPMC hamwe nuburemere bwimbitse bushobora gukora imikoranire myinshi mu gisubizo, bityo igaragaza ubushishozi bwo hejuru.

HydroxyPropyl na methyl gusimbuza methyl: Hejuru ya HydroxyPropyl (-Oh) na methyl (-ch₃) gusimbuza, hejuru yamazi ya HPMC. Kwiyongera mubisimbuza hydroxylepyl birashobora kunoza neza ibyo HPMC, mugihe umubyimba uzamura urusyo.

Igisubizo Cyiza: Kwibanda ku gisubizo cya HPMC bigira ingaruka ku buryo butaziguye. Isumbabyose kwibandaho, niko viscosiya. Muri rusange, ibisubizo hamwe na concentration hagati ya 2% na 5% birasanzwe, kandi viscosity yibisubizo byibandaho byibandaho bizaba birebire.

Solven: HPMC irashonga neza mumazi, niko urujijo rwarwo rusuzumwa hashingiwe ku gisubizo gitangaje. Ariko, ubwoko butandukanye bwimiterere bushobora kandi kugira ingaruka kuke kwiyoroshya no gusya.

Ubushyuhe: Ubushyuhe bugira ingaruka zikomeye kuri viscolity yo gukemura Hpmc. Muri rusange, kwiyongera k'ubushyuhe bizatera kugabanuka kwikibazo kubera ko ubushyuhe bwo hejuru buzahita bugenda kandi bwongera amazi yumuti.

HPMC vicosity ikoreshwa kenshi mumirima ikurikira:

Umurima wa farumasi: Ikoreshwa nkagejejweho harakuweho ibiyobyabwenge, igipimo cya tablet, nibigize ibishishwa bya capsule. Irashobora kwemeza irekurwa ryibiyobyabwenge mu mubiri no kugenzura vicosity.

Inganda zibiribwa: Byakoreshejwe nkumukozi wa dolling, birashobora kunoza neza uburyohe nuburyo bwo kurya, nka ice cream, jelly, bombo, nibindi

Inganda zubwubatsi: Byakoreshejwe nkumukozi wamazi no mu mazi mu bikoresho byo kubaka nka sima na minisiteri kugira ngo imikorere yo kubaka n'imikorere y'ibikoresho.

Inganda zo kwisiga: zikoreshwa mubicuruzwa nka cream, isura yo mumaso, igicucu cyamaso, nibindi. Gutanga viso nziza no gutuza.

Iyo uhisemo ibicuruzwa bibereye HPMC, ni ngombwa gusobanukirwa ibiranga viscosity byagaragaye, cyane cyane ibisabwa kugirango amazi n'umutekano muri porogaramu zitandukanye. Niba hari ibisabwa kubiciro byihariye bya viscosity bya HPMC runaka, urashobora kwerekeza kumakuru ajyanye nibicuruzwa cyangwa ubigeraho hamwe nibikoresho byo gupima visosity.
