Nā waiwai, nā ʻano a me nā hoʻohana o ka hydroxyethyl cellulose

ʻO ka Hydroxyethyl cellulose kahi polymer wai-soluble non-ionic i hana ʻia mai ka cellulose, kahi mea polymer kūlohelohe, ma o kahi moʻo o nā kaʻina hana kemika. He mea paʻa pauka keʻokeʻo a melemele paha, ʻala ʻole a ʻono ʻole, hiki ke hoʻoheheʻe ʻia i loko o ka wai anuanu a me ka wai wela, a piʻi ka nui o ka hoʻoheheʻe ʻana me ka piʻi ʻana o ka mahana. Ma keʻano laulā, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka hapa nui o nā mea hoʻoheheʻe organik. Hoʻohana ʻia ia ma ke ʻano he mea hoʻomānoanoa a me ka mea hoʻopaʻa i ka pena latex. He maʻalahi ke hoʻopuehu i ka wai anuanu me ka waiwai pH ma lalo o 7 a i ʻole like, akā he maʻalahi ke hoʻohuihui i loko o ka wai alkaline, no laila ua hoʻomākaukau mua ʻia no ka hoʻohana ʻana ma hope, a i ʻole ka wai waikawa nāwaliwali a i ʻole ka hopena organik i hana ʻia i slurry, a hiki ke hoʻohui ʻia me nā granular ʻē aʻe. Hoʻohui maloʻo ʻia nā mea hoʻohui.

Nā ʻano o ka hydroxyethyl cellulose:

Hiki ke hoʻoheheʻe ʻia ʻo HEC i ka wai wela a anu paha, a ʻaʻole e hoʻopūʻiʻi ʻia i ka mahana kiʻekiʻe a i ʻole ka paila ʻana, ʻo ia ka mea e loaʻa ai kahi ākea o nā ʻano solubility a me ka viscosity, a me ka gelation non-thermal.

Hiki iā ia ke hui pū me nā ʻano polymers ʻē aʻe e hiki ke hoʻoheheʻe ʻia i ka wai, nā surfactants, a me nā paʻakai, a he mea hoʻomānoanoa colloidal maikaʻi loa no nā hopena e loaʻa ana nā electrolytes kiʻekiʻe.

ʻOi aku ka nui o ka hiki ke paʻa i ka wai ma mua o ka methyl cellulose, a ʻoi aku ka maikaʻi o ka hoʻoponopono ʻana i ke kahe ʻana.

Ke hoʻohālikelike ʻia me ka methyl cellulose i ʻike ʻia a me ka hydroxypropyl methyl cellulose, ʻo ka hiki ke hoʻopuehu ʻo HEC ka mea ʻino loa, akā ʻo ka hiki ke pale colloid ka ikaika loa.

Kūkulu maikaʻi loa; loaʻa iā ia nā pono o ka mālama ʻana i ka hana, ʻaʻole maʻalahi ke kahe, anti-sag, maikaʻi anti-splash, etc.

Hoʻohālikelike maikaʻi me nā ʻano surfactants a me nā preservatives i hoʻohana ʻia i ka pena latex.

He paʻa ka mānoanoa o ka mālama ʻana, hiki ke pale i ka hydroxyethyl cellulose maʻamau mai ka hōʻemi ʻana i ka mānoanoa o ka pena latex i ka wā e mālama ai ma muli o ka palaho ʻana o nā enzymes.
