Hydroxypropyl methylcellulose (HPMC) hiʻona

Hoʻohui ka huahana i nā waiwai kino a me nā kemika e lilo i huahana kūʻokoʻa me nā hoʻohana lehulehu, a penei nā ʻano waiwai like ʻole:

(1) Paʻa wai: Hiki iā ia ke paʻa i ka wai ma nā wahi porous e like me nā papa sima pā a me nā pōhaku lepo.

(2) Hoʻokumu kiʻiʻoniʻoni: Hiki iā ia ke hana i kahi kiʻiʻoniʻoni akaka, paʻakikī a palupalu me ka pale ʻana i ka aila maikaʻi loa.

(3) Hiki ke hoʻoheheʻe ʻia: Hiki ke hoʻoheheʻe ʻia ka huahana i loko o kekahi mau mea hoʻoheheʻe kūlohelohe, e like me ka ethanol/wai, propanol/wai, dichloroethane, a me kahi ʻōnaehana solvent i haku ʻia me ʻelua mau mea hoʻoheheʻe organik.

(4) Thermal gelation: Ke hoʻomehana ʻia ka wai wai o ka huahana, e hana ia i gel, a lilo ka gel i hoʻokumu ʻia i mea hoʻonā ma hope o ka hoʻoilo.

(5) Ka hana ʻili: Hāʻawi i ka hana ʻili i ka hopena e hoʻokō i ka emulsification pono a me ka colloid pale, a me ka hoʻopaʻa ʻana o ka pae.

(6) Hoʻokuʻu: Hiki iā ia ke pale i ka ua o nā mea paʻa paʻa, pēlā e pale ai i ka hoʻokumu ʻana o ka sediment.

(7) Colloid pale: hiki iā ia ke pale i nā droplets a me nā ʻāpana mai ka coalescing a i ʻole coagulating.

(8) Adhesiveness: Hoʻohana ʻia i mea hoʻopili no nā puaʻa, nā huahana paka, a me nā huahana pepa, he hana maikaʻi loa ia.

(9) Hoʻoheheʻe wai: Hiki ke hoʻoheheʻe ʻia ka huahana i ka wai i nā nui like ʻole, a ua kaupalena ʻia kona ʻano kiʻekiʻe e ka viscosity.

(10) Non-ionic inertness: ʻO ka huahana he non-ionic cellulose ether, ʻaʻole i hui pū me nā paʻakai metala a i ʻole nā ​​​​iona ʻē aʻe e hana i nā precipitates insoluble.

(11) Acid-base paʻa: kūpono no ka hoʻohana i loko o ka laulā o PH3.0-11.0.

(12) ʻAʻole ʻono a ʻala ʻole, ʻaʻole pili i ka metabolism;hoʻohana ʻia ma ke ʻano he meaʻai a me nā mea hoʻohui lāʻau, ʻaʻole lākou e hoʻopili ʻia i ka meaʻai a ʻaʻole e hāʻawi i nā calorie.
