ʻO ka Hydroxyethyl cellulose kahi polymer wai-soluble non-ionic i hana ʻia mai ka cellulose, kahi mea polymer kūlohelohe, ma o nā kaʻina hana kemika. He keʻokeʻo a melemele paha, ʻaʻohe ona a me ka ʻono ʻole o ka pauda paʻa paʻa, hiki ke hoʻoheheʻe ʻia i loko o ka wai anuanu a me ka wai wela, a piʻi ka dissolution rate me ka piʻi ʻana o ka mahana. ʻO ka maʻamau, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka hapa nui o nā mea hoʻoheheʻe organik. Hoʻohana ʻia ia e like me ka mānoanoa a me ka stabilizer i ka pena latex. He maʻalahi ka hoʻopuehu ʻana i ka wai anuanu me ka pH ʻoi aku ka liʻiliʻi a i ʻole like me 7, akā maʻalahi ka hoʻohui ʻana i ka wai alkaline, no laila ua hoʻomākaukau mua ʻia no ka hoʻohana ʻana ma hope, a i ʻole ka wai ʻakika nāwaliwali a i ʻole ka hopena organik i hana ʻia i slurry. , a hiki no hoi ke hui pu ia me kekahi granular Ua maloo huiia na mea kanu.
ʻO nā hiʻohiʻona o ka hydroxyethyl cellulose:
Hiki ke hoʻoheheʻe ʻia ka HEC i ka wai wela a i ʻole ka wai anuanu, a ʻaʻole e hoʻoheheʻe ʻia i ke kiʻekiʻe wela a i ʻole ka paila ʻana, kahi e loaʻa ai ka nui o ka solubility a me nā ʻano viscosity, a me ka gelation non-thermal.
Hiki iā ia ke noho pū me ka nui o nā polymers hiki ke hoʻoheheʻe ʻia i ka wai, surfactants, a me nā paʻakai, a he mea hoʻomānoanoa colloidal maikaʻi loa no nā hopena i loaʻa nā electrolytes kiʻekiʻe.
ʻOi aku ka nui o ka paʻa wai ma mua o ka methyl cellulose, a ʻoi aku ka maikaʻi o ka hoʻoponopono kahe.
Ke 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 pale colloid.
Hana maikaʻi loa; Loaʻa iā ia nā pōmaikaʻi o ka mālama ʻana i ka hana, ʻaʻole maʻalahi i ka kulu, anti-sag, anti-splash maikaʻi, etc.
Hoʻopili maikaʻi me nā surfactant like ʻole a me nā preservatives i hoʻohana ʻia i ka pena latex.
Paʻa ka viscosity mālama, hiki ke pale i ka hydroxyethyl cellulose maʻamau mai ka hōʻemi ʻana i ka viscosity o ka pena latex i ka wā o ka mālama ʻana ma muli o ka decomposition o nā enzymes.
