ʻO nā pono o ka Pharmaceutical Grade HPMC

Ua lilo ʻo HPMC i hoʻokahi o nā mea hoʻohana lāʻau lapaʻau i hoʻohana nui ʻia ma ka home a ma waho, no ka mea he mau pono ko HPMC ʻaʻole i loaʻa i nā mea kōkua ʻē aʻe.

1. Ka hoʻoheheʻe wai

Hiki ke hoʻoheheʻe ʻia i ka wai anuanu ma lalo o 40°C a i ʻole 70% ethanol, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai wela ma luna o 60°C, akā hiki ke gel.

2. Kemika inertness

ʻO HPMC kahi ʻano non-ioniccellulose etera.ʻAʻohe o ka hoʻonā ionic charge a ʻaʻole pili pū me nā paʻakai metala a i ʻole nā ​​pūhui organik ionic.No laila, ʻaʻole i pane aku nā mea ʻē aʻe me ia i ka wā o ka hoʻomākaukau ʻana.

3. Paʻa

He paʻa paʻa ia i ka waikawa a me ka alkali, a hiki ke mālama ʻia no ka manawa lōʻihi ma waena o ka pH 3 a me 11 me ka ʻole o ka loli ʻana o ka viscosity.He hopena anti-mildew ka hopena wai o HPMC a hiki ke mālama i ka paʻa viscosity maikaʻi i ka wā mālama lōʻihi.ʻOi aku ka maikaʻi o ka paʻa o nā lāʻau lapaʻau e hoʻohana ana i ka HPMC ma ke ʻano he mea hoʻomākaukau hoʻomākaukau ma mua o nā lāʻau lapaʻau e hoʻohana ana i nā mea hoʻohui kuʻuna (e like me ka dextrin, starch, etc.).

4. Hiki ke hoʻololi i ka viscosity

Hiki ke hui pū ʻia nā derivatives viscosity like ʻole o HPMC e like me nā lakio like ʻole, a hiki ke hoʻololi i kona viscosity e like me kekahi mau lula, a he pilina laina maikaʻi, no laila hiki ke koho ʻia ka lākiō e like me nā koi.2.5 Metabolism inert HPMC ʻaʻole i komo a metabolized i loko o ke kino, ʻaʻole hāʻawi i ka wela, no laila he mea hoʻomākaukau lāʻau palekana palekana..

5. Palekana

Manaʻo ʻia ʻo HPMC he mea ʻawaʻawa ʻole a hoʻonāukiuki ʻole.
