Focus on Cellulose ethers

ʻO ke koʻikoʻi a me ka hoʻohana ʻana i ka Hydroxyethyl Cellulose

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. Hiki ke hoʻoheheʻe ʻia ka HEC i ka wai wela a i ʻole ka wai anuanu, a 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 colloid pale.

3. Ka hoʻohana ʻana i ka hydroxyethyl cellulose

Hoʻohana maʻamau e like me nā mānoanoa, nā mea pale, nā mea hoʻopili, nā 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 hydrophilic gels, 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.
