1. Nā waiwai o ka hydroxyethyl cellulose
ʻO kēia huahana he keʻokeʻo a i ʻole ka melemele māmā ʻole a me ka maʻalahi kahe o ka pauka, 40 mesh sieve rate ≥99%;ka mahana palupalu: 135-140°C;ʻike maka: 0.35-0.61g/ml;ka wela decomposition: 205-210°C;ka wikiwiki o ka puhi ʻana.ka mahana kaulike: 23°C;6% ma 50%rh, 29% ma 84%rh.
Hiki ke hoʻoheheʻe ʻia i ka wai anuanu a me ka wai wela, a ʻaʻole hiki ke hoʻoheheʻe ʻia i ka hapa nui o nā mea hoʻoheheʻe organik.Hoʻololi iki ka viscosity i ka laulā o ka waiwai PH 2-12, akā e emi ana ka viscosity ma mua o kēia pae.
2. Nā waiwai nui
Ma ke ʻano he surfactant non-ionic,hydroxyethyl celluloseLoaʻa iā ia nā waiwai e pili ana i ka mānoanoa, hoʻopaneʻe, hoʻopaʻa, lana, hana kiʻiʻoniʻoni, hoʻopuehu, mālama wai a hāʻawi i ka colloid pale:
1. He mea hiki ke hoʻoheheʻe ʻia ka HEC i ka wai wela a i ʻole ka wai anuanu, ʻaʻole e hoʻoheheʻe ʻia i ka wela kiʻekiʻe a i ʻole ka paila ʻana, kahi e loaʻa ai ka nui o ka solubility, nā hiʻohiʻona viscosity a me ka gelation non-thermal.
2. ʻAʻole ionic a hiki ke noho pū me ka nui o nā polymers hiki ke hoʻoheheʻe ʻia i ka wai, surfactants, a me nā paʻakai.He mānoanoa colloidal maikaʻi loa ia no nā hoʻonā 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. Ke hoʻohālikelike ʻia me ka methyl cellulose i ʻike ʻia a me ka hydroxypropyl methyl cellulose, ʻo HEC ka mea hiki ke hoʻopuehu maikaʻi loa, akā ʻoi aku ka ikaika o ka pale colloid.
3. Ka hoʻohana ʻana i ka hydroxyethyl cellulose
Hoʻohana maʻamau e like me nā mānoanoa, nā mea pale, adhesives, stabilizers a me nā mea hoʻohui no ka hoʻomākaukau ʻana i nā emulsions, jellies, ʻaila, lotions, nā mea hoʻomaʻemaʻe maka, suppositories a me nā papa, a hoʻohana pū ʻia e like me nā gels hydrophilic, nā mea iwi, hiki ke hoʻohana ʻia e hoʻomākaukau i ka matrix- ʻano hoʻomākaukau hoʻokuʻu hoʻomau, a hiki ke hoʻohana ʻia ma ke ʻano he stabilizer i ka meaʻai.
