Cellulose, hydroxyethyl ether (MW 1000000)

Cellulose hydroxyethyl etherhe mea ia o ka cellulose, he polymer maoli i loaʻa i loko o nā paia o nā mea kanu. ʻO ka hoʻololi ʻana o ka hydroxyethyl ether e pili ana i ka hoʻokomo ʻana i nā pūʻulu hydroxyethyl i ka hale cellulose. ʻO ke kaumaha molekala (MW) i kuhikuhi ʻia he 1,000,000 paha e pili ana i ka awelika kaumaha molekala o ka cellulose hydroxyethyl ether. Eia kekahi mau mea nui e pili ana i ka cellulose hydroxyethyl ether me ke kaumaha mole o 1,000,000:

1. Hoʻolālā Kimia:
   • Loaʻa ʻia ka cellulose hydroxyethyl ether mai ka cellulose ma ka hana ʻana me ka ethylene oxide, ka hopena i ka hoʻokomo ʻana o nā pūʻulu hydroxyethyl i ka iwi kuamoʻo cellulose.
2. Kaumaha Molekala:
   • ʻO ke kaumaha molekala o 1,000,000 e hōʻike ana i ka awelika molecular kaumaha o ka cellulose hydroxyethyl ether. He ana keia waiwai o ka nuipa awelika o na kaulahao polymer i ka laana.
3. Nā waiwai kino:
   • ʻO nā waiwai kino kūikawā o ka cellulose hydroxyethyl ether, e like me ka solubility, viscosity, a me ka hiki ke hana gel, e hilinaʻi ʻia i nā mea e like me ke degere o ka hoʻololi ʻana (DS) a me ke kaumaha mole. Hiki ke hoʻololi i nā kaumaha molekala kiʻekiʻe i ka viscosity a me ke ʻano rheological o nā hāʻina.
4. Hiki ke hoʻoheheʻe:
   • Hiki ke hoʻoheheʻe ʻia ka cellulose hydroxyethyl ether i ka wai. Hiki ke hoʻololi i ka degere o ka hoʻololi ʻana a me ke kaumaha molekala i kona solubility a me ka neʻe ʻana o ka hoʻonā ʻana.
5. Nā noi:
   • ʻO ka cellulose hydroxyethyl ether me ke kaumaha molekala o 1,000,000 hiki ke loaʻa nā noi i nā ʻoihana like ʻole:
     • Lapaʻau Lapaʻau: Hiki ke hoʻohana ʻia i loko o ka hoʻokuʻu ʻana i nā lāʻau lapaʻau i hoʻokuʻu ʻia, nā uhi papa, a me nā noi lāʻau lapaʻau ʻē aʻe.
     • Nā mea hana: I loko o ka mortar, plaster, a me nā mea hoʻopili tile e hoʻomaikaʻi ai i ka mālama ʻana i ka wai a me ka hana.
     • Nā Kiʻiʻoniʻoni a me nā Kiʻiʻoniʻoni: I ka hanaʻana i nā pale a me nā kiʻiʻoniʻoni no kāna mau mea hana kiʻiʻoniʻoni.
     • Nā huahana mālama pilikino: I nā mea hoʻonaninani a me nā mea mālama pilikino no kona mānoanoa a me ka hoʻopaʻa ʻana i nā waiwai.
6. Mana Rheological:
   • ʻO ka hoʻohui ʻana o cellulose hydroxyethyl ether hiki ke hāʻawi i ka mana ma luna o nā waiwai rheological o nā hoʻonā, e hoʻolilo iā ia i mea waiwai i nā formulations kahi e pono ai ka mana viscosity.
7. Hiki i ka biodegradability:
   • ʻO ka cellulose ethers, me ka hydroxyethyl ether derivatives, he mea biodegradable maʻamau, e hāʻawi ana i kā lākou ʻike pili kaiapuni.
8. Hoʻohui:
   • Hoʻopili ka synthesis i ka hopena o ka cellulose me ka ethylene oxide i mua o ka alkali. Hiki ke hoʻomalu ʻia ke degere o ka hoʻololi ʻana a me ke kaumaha molekala i ke kaʻina hana synthesis.
9. Noiʻi a hoʻomohala:
   • Hiki i nā mea noiʻi a me nā mea hoʻokumu ke koho i nā cellulose hydroxyethyl ethers e pili ana i ka paona molekala a me ke kiʻekiʻe o ka hoʻololi e hoʻokō i nā waiwai i makemake ʻia i nā noi like ʻole.

He mea nui e hoʻomaopopo e hiki ke ʻokoʻa nā waiwai a me ka hoʻohana ʻana o cellulose hydroxyethyl ether ma muli o kāna mau hiʻohiʻona kikoʻī, a ʻo ka ʻike i ʻōlelo ʻia e hāʻawi i kahi ʻike ākea. ʻO ka ʻikepili kikoʻī kikoʻī i hāʻawi ʻia e nā mea hana a mea hoʻolako paha he mea koʻikoʻi no ka hoʻomaopopo ʻana i ka huahana cellulose hydroxyethyl ether kikoʻī i nīnau ʻia.
