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.

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. HEC hiki ke hoʻoheheʻe ʻia i loko o ka wai wela a i ʻole ka wai anuanu, 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 mea hoʻonaninani colloidal 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 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.

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 ʻano 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 hoʻoheheʻe wai.

9. Paʻa i nā kemika, mālama lōʻihi me ka pōʻino ʻole.

10. Hoʻohālikelike me nā resins he nui a me ka hoʻohālikelike 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.
