ʻAʻole hiki i nā poʻe he nui ke haʻi i ka ʻokoʻa ma waena o ka hydroxyethyl cellulose a me ka ethyl cellulose.ʻO Hydroxyethyl cellulose a me ka ethyl cellulose ʻelua mau mea like ʻole.Loaʻa iā lākou nā hiʻohiʻona.
1 Hydroxyethyl cellulose:
Ma ke ʻano he surfactant non-ionic, ma waho aʻe o ka mānoanoa, hoʻopaneʻe, hoʻopaʻa ʻia, flotation, hana kiʻiʻoniʻoni, hoʻopuehu, mālama i ka wai a me ka hāʻawi ʻana i nā colloids pale, loaʻa iā ia nā waiwai aʻe:
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, e hana ana i kahi ākea o ka solubility a me nā ʻano 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, 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. Ke hoʻohālikelikeʻia me ka methyl cellulose iʻikeʻia a me ka hydroxypropyl methyl cellulose,ʻo ka hiki ke hoʻopuehu o HEC ka meaʻoi loa, akāʻo ka colloid pale ka ikaika loa.
2 Ethyl cellulose
ʻO ia ka non-ionic cellulose ether ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai akā hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik.Loaʻa iā ia nā hiʻohiʻona penei:
1. ʻAʻole maʻalahi e puhi.
2. ʻO ke kūpaʻa wela maikaʻi a me ka thermoplasticity maikaʻi loa.
3. ʻAʻohe hoʻololi i ka lā.
4. Hiki ke hoʻololi maikaʻi.
5. Nā waiwai dielectric maikaʻi.
6. Loaʻa iā ia ke kūpaʻa alkali maikaʻi a me ke kūpaʻa ʻakika nāwaliwali.
7. Hana maikaʻi anti-kahiko.
8. Ke kū'ē maikaʻi i ka paʻakai, ke anu a me ka hoʻoheheʻeʻana i ka wai.
9. Paʻa i nā kemika, mālama lōʻihi me ka pōʻino ʻole.
10. Hoʻohālikelike me nā resins he nui a me ka launa maikaʻi me nā plasticizers āpau.
11. He mea maʻalahi ke hoʻololi i ke kala ma lalo o ke kaiapuni alkaline ikaika a me nā kūlana wela.
