Nā waiwai o Hydroxyethyl Cellulose

Hydroxyethyl cellulose

He polymer non-ionic wai-soluble, keʻokeʻo a i ʻole melemele liʻiliʻi, maʻalahi ka kahe ʻana o ka pauka, ʻaʻohe ʻono a ʻono ʻole, hiki ke hoʻoheheʻe ʻia i ka wai anuanu a me ka wai wela, a piʻi ka dissolution rate me ka piʻi ʻana o ka mahana.ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik.

Nā waiwai o ka hydroxyethyl cellulose:

1. He mea hiki ke hoʻoheheʻe ʻia ʻo HEO i ka wai wela a i ʻole ka wai anuanu, ʻaʻole e hoʻoheheʻe ʻia i ka wela kiʻekiʻe a i ʻole ka paila ʻana, no laila he ākea ka nui o ka solubility a me nā ʻano viscosity, a me ka gelation non-thermal.

2. Hiki i ka non-ionic pono'ī ke noho pū me ka nui o nā polymers hiki ke hoʻoheheʻe ʻia i ka wai, surfactants a me nā paʻakai, a he mea hoʻonaninani colloidal maikaʻi loa no nā hopena electrolyte kiʻekiʻe.

3. ʻO ka paʻa wai paʻa ʻelua ʻoi aku ka nui o ka methyl cellulose, a ʻoi aku ka maikaʻi o ka hoʻoponopono kahe ʻana.

4. Hoʻohālikelike ʻia me ka methyl cellulose i ʻike ʻia a me ka hydroxypropyl methyl cellulose, ʻoi aku ka maikaʻi o ka hoʻopuehu ʻana o HEC, akā ʻoi aku ka ikaika o ka colloid pale.
