ʻO ka mea hoʻomaʻemaʻe hale hana ʻenehana cellulose ʻoihana Kemika HPMC cellulose ether Hydroxypropyl methyl cellulose

1) ʻAno: ʻO ka HPMC he cellulose ether nonionic, keʻokeʻo keʻokeʻo hina keʻokeʻo a i ʻole granule, ʻala ʻole a ʻono ʻole, hiki ke hoʻoheheʻe ʻia i loko.

wai anuanu, ʻakika acetic glacial, ethanol, methanol a me propylene glycol, hiki ke hoʻoheheʻe iki i ka acetone ma muli o ke degere o

nā mea hoʻololi, hiki ʻole i ka wai wela, ethylene glycol a me toluene. Hoʻoheheʻe ʻia ka HPMC i kahi hui ʻana o 10% methanol

a me 90% methylene chloride e hana i nā hāʻina colloidal.
2) Loaʻa i ka hopena o HPMC ka hana ma luna, ke aniani kiʻekiʻe, a me ka hana paʻa. Ke wela i kekahi mahana

lilo ka hopena i ao a i ʻole e hana i ka gel flocculent. Eia nō naʻe, akaka hou ka hopena ma hope o ka hoʻomaloʻo ʻana. Nā ʻano like ʻole o

Loaʻa i ka HPMC nā mahana gelation ʻokoʻa. ʻOkoʻa ka solubility me ka viscosity. ʻO ka haʻahaʻa o ka viscosity, ʻoi aku ka nui o ka solubility

ua loaa. ʻOkoʻa nā ʻano like ʻole o ka HPMC i kekahi mau waiwai a ʻaʻole pili ka pH i ko lākou solubility i ka wai.
3) Ka nui o nā ʻāpana: 100% ka nui o ka hala ma 80 mesh.
4) ʻIke ʻia ka haʻahaʻa: 0.25-0.70 g/mL (maʻamau ma kahi o 0.5 g/mL), 1.26-1.31mL kikoʻī.
5) Ka wela hoʻololi kala: 190-200 ° C; ʻO ka mahana carbonization: 280-300 ° C.
6) Kūleʻa o ka ʻili: 42-56 dyn/cm (2% aqueous solution).
7) ʻO ka maʻiʻo methoxy kiʻekiʻe ma HPMC, ka haʻahaʻa haʻahaʻa o ka gelation, a me ka solubility kiʻekiʻe i ka wai a me ka hana ma luna.
8) Loaʻa i ka HPMC kekahi mau hiʻohiʻona ʻē aʻe, no ka laʻana, ka waiwai mānoanoa, ka paʻa pH, ka paʻa ʻana o ka wai, ka hana kiʻiʻoniʻoni maikaʻi loa.

waiwai, hoʻopuehu maikaʻi a me ka hiki ke hoʻopili.
