ʻElua mau mea like ʻole ka Hydroxyethyl cellulose a me ka ethyl cellulose. Loaʻa iā lāua nā ʻano penei.
ʻO ka cellulose hydroxyethyl
Ma ke ʻano he surfactant non-ionic, me ka hoʻomānoanoa, ka hoʻokuʻu ʻana, ka nakinaki ʻana, ka flotation, ka hana ʻana i nā kiʻiʻoniʻoni, ka hoʻopuehu ʻana, ka mālama ʻana i ka wai a me ka hāʻawi ʻana i nā colloids pale, loaʻa iā ia nā waiwai penei:
1. Hiki ke hoʻoheheʻe ʻia ʻo HEC i ka wai wela a anuanu paha, a ʻaʻole e hoʻopūʻiwa i ka mahana kiʻekiʻe a i ʻole ka paila ʻana, no laila he ākea ka laulā o nā ʻano solubility a me ka viscosity, a me ka gelation non-thermal;
2. Hiki i ka non-ionic ponoʻī ke noho pū me kahi ākea o nā polymers wai-soluble ʻē aʻe, nā surfactants a me nā paʻakai, a he mea hoʻomānoanoa colloidal maikaʻi loa e loaʻa ana nā hopena electrolyte kiʻekiʻe;
3. ʻOi aku ka nui o ka hiki ke mālama i ka wai ma mua o ka methyl cellulose, a ʻoi aku ka maikaʻi o ke kahe ʻana o ke kahe;
4. Ke hoʻohālikelike ʻia me ka methyl cellulose i ʻike ʻia a me ka hydroxypropyl methyl cellulose, ʻo ka hiki ke hoʻopuehu ʻia o HEC ka mea ʻino loa, akā ʻo ka colloid pale ka mea ikaika loa.
ʻEtila kelulosa
He ʻetera cellulose non-ionic ia i hoʻoheheʻe ʻole ʻia i ka wai akā hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik. Loaʻa iā ia nā ʻano penei:
1. ʻAʻole maʻalahi ke puhi.
2. Paʻa maikaʻi ka wela a me ka thermoplasticity maikaʻi loa.
3. ʻAʻohe loli i ka lā.
4. Maikaʻi ka maʻalahi.
5. Nā waiwai dielectric maikaʻi.
6. He kūpaʻa alkali maikaʻi loa a me ke kūpaʻa waikawa nāwaliwali.
7. Hana maikaʻi anti-kahiko.
8. Kū'ē maika'i i ka pa'akai, ke anu a me ka omo wai.
9. Paʻa i nā kemika, mālama lōʻihi me ka ʻole o ka pala.
10. Kūlike 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.
