Ka waiwai o ka mahana o ka gel i loko o ka hydroxypropyl methylcellulose

1. Mahana o ka gel (0.2% solution) 50-90°C.

2. Hoʻoheheʻe ʻia i ka wai a me ka hapa nui o ka polar c a me ka hapa kūpono o ka ethanol/wai, propanol/wai, dichloroethane, a me nā mea ʻē aʻe, ʻaʻole hoʻoheheʻe ʻia i ka ether, acetone, ethanol piha, a pehu i loko o ka wai anuanu colloidal solution maopopo a ʻūlū iki paha. Loaʻa i ka hopena wai ka hana ʻili, kiʻekiʻe ka transparency a me ka hana paʻa.

3. Loaʻa i ka HPMC ka waiwai o ka gelation thermal. Hoʻomehana ʻia ka hopena wai o ka huahana e hana i kahi gel a hoʻoheheʻe ʻia, a laila hoʻoheheʻe ʻia ma hope o ka hoʻomaʻalili ʻana. He 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 i nā kikoʻī like ʻole o ka HPMC kekahi mau ʻokoʻa i ko lākou mau waiwai, a ʻaʻole i hoʻopilikia ʻia ka hoʻoheheʻe ʻana o HPMC i ka wai e ka waiwai pH.

4. Ka nui o nā ʻāpana: ʻOi aku ka nui o ka hala ʻana o 100 mesh ma mua o 98.5%. Ka nui o ka nui: 0.25-0.70g/ (ma kahi o 0.4g/), ke kaumaha kikoʻī 1.26-1.31. Ka mahana hoʻololi kala: 180-200°C, ka mahana kalapona: 280-300°C. Loaʻa ka waiwai methoxyl mai 19.0% a 30.0%, a ʻo ka waiwai hydroxypropyl mai 4% a 12%. Ka mānoanoa (22°C, 2%) 5～200000mPa .s. Ka mahana gel (0.2%) 50-90°C

5. Loaʻa iā HPMC nā ʻano o ka hiki ke hoʻomānoanoa, ka hoʻokuʻu ʻana o ka paʻakai, ke kūpaʻa PH, ka paʻa ʻana o ka wai, ke kūpaʻa dimensional, ka waiwai hoʻokumu kiʻiʻoniʻoni maikaʻi loa, ka laulā o ke kū'ē ʻana o ka enzyme, ka dispersibility a me ke cohesiveness.
