Nā hopena o ka wela ma ka Hydroxy Ethyl Cellulose Solution

ʻO ka Hydroxy Ethyl Cellulose (HEC) he polymer wai-soluble i hoʻohana nui ʻia i nā ʻoihana like ʻole e like me nā mea hoʻonaninani, nā lāʻau lapaʻau, a me nā meaʻai e like me ka mānoanoa, binder, a me ka stabilizer. ʻO ka viscosity o nā hāʻina HEC e hilinaʻi nui ʻia i ka mahana, a hiki i nā loli i ka mahana ke hoʻopilikia i nā waiwai kino o ka hopena.

Ke hoʻonui ʻia ka mahana o ka hopena HEC, e emi ana ka viscosity o ka hopena ma muli o ka emi ʻana o ka hoʻopaʻa hydrogen ma waena o nā kaulahao polymer. ʻOi aku ka haʻi ʻana o kēia emi ʻana o ka viscosity i nā wela kiʻekiʻe a loaʻa i kahi hopena ʻoi aku ka lahilahi a me ka wai.

ʻO ka mea ʻē aʻe, ke hoʻemi ʻia ka mahana o ka solution HEC, piʻi ka viscosity o ka hopena ma muli o ka hoʻonui ʻia ʻana o ka hydrogen paʻa ma waena o nā kaulahao polymer. ʻO kēia piʻi ʻana o ka viscosity i ʻōlelo ʻia ma nā haʻahaʻa haʻahaʻa a loaʻa i kahi hopena ʻoi aku ka mānoanoa, e like me ka gel.

Eia hou, hiki ke hoʻololi i ka mahana i ka solubility o HEC i ka wai. Ma nā wela kiʻekiʻe, hiki ke hoʻoheheʻe ʻia ka HEC i ka wai, ʻoiai ma nā mahana haʻahaʻa, emi ka HEC i ka wai.

Ma keʻano holoʻokoʻa, pili nā hopena o ka mahana ma ka hopena HEC i ka ʻike ʻana o ka polymer, ke ʻano o ka solvent, a me ka noi kikoʻī o ka solution HEC.
