Hoohana Huahana
ʻO Carboxymethyl cellulose (CMC) he pauka flocculent keʻokeʻo non-toxic a ʻono ʻole me ka hana paʻa a maʻalahi hoʻi e hoʻoheheʻe i ka wai.ʻO kona wai hoʻoheheʻe he kūʻokoʻa a i ʻole alkaline transparent viscous wai, hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻopili wai a me nā resins ʻē aʻe, a hiki ʻole ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol.Hiki ke hoʻohana ʻia ʻo CMC e like me ka binder, thickener, suspension agent, emulsifier, dispersant, stabilizer, sizing agent, etc. ʻO Carboxymethyl cellulose (CMC) ka hua nui loa o ka cellulose ether, ka mea i hoʻohana nui ʻia, ka huahana kūpono loa, i ʻike ʻia ʻo " ʻoihana MSG".
Detergency
1. ʻO ka sodium carboxymethyl cellulose he surfactant, hiki ke hoʻohana ʻia ma ke ʻano he anti-fouling re-deposition, ʻo ia ka dispersant a me ka surfactant o nā ʻāpana stain, e hana ana i kahi papa adsorption paʻa i ka ʻili e pale ai i kona adsorption hou ma ka fiber. .
2. Ke hoʻohui ʻia ka sodium carboxymethyl cellulose i ka pauka holoi, hiki ke hoʻopuehu like ʻia ka hopena a hoʻopili maʻalahi i ka ʻili o nā mea paʻa paʻa, e hana ana i kahi papa o ka adsorption hydrophilic a puni nā ʻāpana paʻa.A laila ʻoi aku ka liʻiliʻi o ka ʻili o ka ʻili ma waena o ka wai a me nā ʻāpana paʻa ma mua o ka neʻe ʻana o ka ʻili i loko o nā ʻāpana paʻa, a ʻo ka hopena pulu o ka mole surfactant e hoʻopau i ka hui ʻana ma waena o nā ʻāpana paʻa.Hoʻopuehu kēia i ka lepo i loko o ka wai.
3. Hoʻohui ʻia ka sodium carboxymethyl cellulose i ka pauka holoi lole, nona ka hopena emulsifying.Ma hope o ka emulsifying aila unahi, ʻaʻole maʻalahi e hōʻiliʻili a hoʻoheheʻe i ka lole.
4. Hoʻohuiʻia ka sodium carboxymethyl cellulose i ka pauka holoi lole, he hopena pulu a hiki ke komo i loko o nā'āpana lepo hydrophobic, eʻoki ana i nā'āpana lepo i loko o nā'āpana colloidal, i maʻalahi ka lepo e haʻalele i ka fiber.
