ʻO Hydroxyethyl cellulose a me ka ethyl cellulose ʻelua mau mea like ʻole. Loaʻa iā lākou nā ʻano.
Hydroxyethyl cellulose
Ma ke ʻano he surfactant non-ionic, ma waho aʻe o ka mānoanoa, hoʻopaneʻe, hoʻopaʻa, 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, a ʻaʻole e hoʻoheheʻe ʻia i ka wela kiʻekiʻe a i ʻole ka paila, i loaʻa iā ia kahi 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 ka nui o nā polymers hiki ke hoʻoheheʻe ʻia i ka wai, surfactants a me nā paʻakai, a he colloidal mānoanoa maikaʻi loa i loaʻa nā hopena electrolyte kiʻekiʻe;
3. ʻO ka paʻa wai paʻa ʻelua ʻoi aku ka kiʻekiʻe ma mua 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.
Ethyl cellulose
ʻO ia ka non-ionic cellulose ether i hiki ʻole 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 ka waihoʻoluʻu ma lalo o ke kūlana alkaline ikaika a me nā kūlana wela.
