Te Whakatau Maama mo te Kounga o Hydroxypropyl MethylCellulose

Ko te Hydroxypropyl Methylcellulose (HPMC) he polymer e whakamahia nuitia ana i roto i te umanga rongoa hei awhina, hei kaihoko whakakikorua ranei mo nga papa me nga potae.Ka taea te whakatau i te kounga o te HPMC ma te maha o nga tawhā, penei i te viscosity, te makuku, te tohatoha rahi matūriki, me te ma.

Ko tetahi huarahi ngawari ki te whakatau i te kounga o te HPMC ko te ine i tona pokey.Ko te Viscosity he inenga o te parenga o te wai ki te rere, a he mea hono tika ki te taumaha ngota o te HPMC.Ko te HPMC te taumaha teitei ake ka nui ake te potata i te HPMC taumahatanga ngota iti ake.Na reira, ko te teitei ake o te pokey o te HPMC, ko te teitei ake o tona kounga.

Ko tetahi atu tawhā nui ki te whakaaro ko te ihirangi makuku o HPMC.Ko te nui o te makuku ka arahi ki te paheketanga o te HPMC, ka taea te whakaiti i te whai huatanga.Ko te whānuitanga o te makuku e whakaaetia ana mo te HPMC he rereke i runga i te tikanga o te whakamahinga, engari ko te tikanga me iti iho i te 7%.

Ko te tohatoha rahi matūriki o te HPMC he take nui ki te whakatau i tona kounga.Ko te HPMC me te tohatoha rahi matūriki whaiti he pai ake na te mea ka taea e ia he hua riterite me te riterite.Ka taea te whakatau i te tohatoha rahi o te matūriki ma te whakamahi i nga momo tikanga penei i te diffraction laser me te microscopy.

Ka mutu, me aromatawai ano te ma o HPMC.Ka taea te whakatau i te ma o te HPMC ma te wetewete i tana hanganga matū ma te whakamahi i nga tikanga penei i te chromatography wai mahi teitei (HPLC) ranei Fourier-transform infrared spectroscopy (FTIR).Ko nga poke i roto i te HPMC ka pa ki tona haumaru me te kaha.

Hei mutunga, ka taea te whakatau i te kounga o te HPMC ma te ine i tona poiketanga, te makuku, te tohatoha rahi matūriki, me te ma.Ka taea te aromatawai ngawari enei tawhā ma te whakamahi i nga momo tikanga, me te HPMC-kounga teitei kia nui te pokey, iti te makuku, whaiti te tohatoha matūriki, me te ma.
