Hydroxypropyl Methyl Cellulose HPMC Transparency

ʻO ke aniani kiʻekiʻe a me ka hana paʻa.

Loaʻa i ka HPMC ka waiwai o ka thermal gelation. Hoʻomaʻamaʻa ʻia ka hopena wai wai e hana i kahi gel a hoʻoheheʻe ʻia, a laila hoʻoheheʻe ʻia ma hope o ka hoʻoilo. ʻOkoʻa ka mahana gelation o nā kikoʻī like ʻole. ʻokoʻa ka solubility me ka viscosity. ʻO ka haʻahaʻa o ka viscosity, ʻoi aku ka nui o ka solubility. Loaʻa nā ʻokoʻa like ʻole o ka HPMC i kā lākou mau waiwai, a ʻaʻole pili ka hoʻoheheʻe ʻana o HPMC i ka wai e ka pH waiwai.

ʻOi aku ka nui o nā ʻāpana: 100 mesh pass rate ma mua o 98.5%.

ʻAno nui: 0.25-0.70g/ (maʻa mau ma kahi o 0.4g/), ʻumekaumaha kikoʻī 1.26-1.31.

Ka wela hoʻololi: 200-200°C,

Ka wela o ka carbonization: 280-300°C.

Ka waiwai Methoxy 19.0% a 30.0%,

Waiwai Hydroxypropyl 4% a 12%.

ʻOka (22℃, 2%) 5~200000mPa.s.

ʻO ka mahana gel (0.2%) he 50-90 ° C.

Loaʻa i ka HPMC nā hiʻohiʻona o ka hiki ke mānoanoa, ka hoʻokuʻu ʻana o ka paʻakai, ka paʻa PH, ka paʻa ʻana o ka wai, ke kūpaʻa dimensional, ka waiwai hana kiʻiʻoniʻoni maikaʻi loa a me ka laulā o ke kūpaʻa enzyme, dispersibility a me ka cohesiveness.
