Ma ke ʻano he surfactant non-ionic,hydroxyethyl cellulose(HEC) nā waiwai aʻe ma waho aʻe o ka mānoanoa, hoʻopaneʻe, hoʻopaʻa ʻana, flotation, hana kiʻiʻoniʻoni, hoʻopuehu, mālama i ka wai a me ka hāʻawi ʻana i nā colloids 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 ke kiʻekiʻe o ka wela a i ʻole ka paila, no laila he ākea ākea o ka solubility a me nā ʻano viscosity, a me ka gelation non-thermal;
2. Hiki i ka non-ionic pono'ī ke noho pū me nā polymers hiki ke hoʻoheheʻe ʻia i ka wai, surfactants a me nā paʻakai ma kahi ākea, a he mea hoʻonaninani colloidal maikaʻi loa i loaʻa nā hopena 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. 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 colloid pale.
Pehea e hoʻohana ai i ka hydroxyethyl cellulose？
1. Hui pololei i ka hana
1. E hoʻohui i ka wai maʻemaʻe i loko o kahi bākeke nui i hoʻolako ʻia me kahi mea hoʻoheheʻe kiʻekiʻe.
2. E hoʻomaka i ka hoʻoulu ʻana me ka māmā haʻahaʻa a e kānana mālie i ka hydroxyethyl cellulose i loko o ka hopena.
3. E hoʻomau i ka hoʻoulu ʻana a hiki i ka pau ʻana o nā ʻāpana āpau.
4. A laila e hoʻohui i ka mea mālama uila, nā mea hoʻohui alkaline e like me nā puaʻa, nā mea hoʻopuehu, ka wai amonia.
5. E hoʻoulu a hiki i ka pau ʻana o ka hydroxyethyl cellulose (e piʻi nui ka viscosity o ka hopena) ma mua o ka hoʻohui ʻana i nā mea ʻē aʻe i loko o ke ʻano, a wili a lilo ia.
