ʻO ka sodium carboxymethyl cellulosehe anionic cellulose ether me ke keʻokeʻo a i ʻole melemele liʻiliʻi flocculent fibrous pauda a i ʻole ka pauda keʻokeʻo ma ke ʻano, ʻaʻohe ʻala, ʻono ʻole a ʻona ʻole; hiki ke hoʻoheheʻe ʻia i loko o ka wai anuanu a i ʻole ka wai wela e hana i kahi hopena akaka me kekahi viscosity, ʻaʻole kū ʻole ka hopena a i ʻole alkaline iki; hiki ʻole ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol, ether, isopropanol, acetone, a me nā mea ʻē aʻe, hiki ke hoʻoheheʻe ʻia i loko o 60% wai ethanol a i ʻole ka hopena acetone.
He hygroscopic, paʻa i ka māmā a me ka wela, ke emi nei ka viscosity me ka piʻi ʻana o ka mahana, paʻa ka hopena i ka waiwai PH o 2-10, ʻoi aku ka haʻahaʻa o ka PH ma mua o 2, aia ka ua paʻa, a ʻoi aku ka kiʻekiʻe o ka PH ma mua o 10, ua emi ka viscosity. ʻO 227 ℃ ka mahana o ka discoloration, ʻo ka mahana carbonization he 252 ℃, a ʻo ka ʻili o ka 2% aqueous solution he 71mn/n.
ʻO kēia ka waiwai kino o ka sodium carboxymethyl cellulose, pehea ka paʻa?
Paʻa loa nā waiwai kino o ka sodium carboxymethyl cellulose, no laila ke hāʻawi nei i kahi pauka keʻokeʻo a melemele paha. Hiki ke hoʻohana ʻia kona kala ʻole, ʻala a me nā mea ʻawaʻawa i nā manawa like ʻole, e like me ka ʻoihana meaʻai, ʻoihana kemika, etc.; I ka manawa like, he mea hoʻoheheʻe maikaʻi loa ia a hiki ke hoʻoheheʻe ʻia i loko o ka wai anuanu a i ʻole ka wai wela e hana i kahi gel, a ʻo ka hopena dissolved he neutral a nāwaliwali alkaline, no laila hiki ke hoʻohana ʻia i ka nui o nā noi a lawe mai i nā hopena maikaʻi aʻe.
ʻO ia no ka mea hiki ke hoʻohana i ka sodium carboxymethyl cellulose i nā manawa he nui i ka hana a me ke ola. ʻOiaʻiʻo, paʻa loa kona mau waiwai kino, a ʻo nā pōmaikaʻi e hiki ke lawe mai e ʻike nui ʻia, e ʻae iā mākou e hauʻoli i kahi manaʻo ʻokoʻa.
