He aha ka sodium cmc?

ʻO Sodium Carboxymethyl Cellulose (CMC) he polymer hiki ke hoʻoheheʻe ʻia i ka wai i loaʻa mai ka cellulose, he polysaccharide kūlohelohe i loaʻa i loko o nā paia cell o nā mea kanu. Hoʻopuka ʻia ka CMC ma o ka mālama ʻana i ka cellulose me ka sodium hydroxide a me ka waikawa monochloroacetic, ka hopena i kahi huahana me nā hui carboxymethyl (-CH2-COOH) i hoʻopili ʻia i ka iwi kuamoʻo cellulose.

Hoʻohana maʻamau ʻia ʻo CMC i nā ʻoihana like ʻole, me ka meaʻai, nā lāʻau lapaʻau, mālama pilikino, a me nā noi ʻoihana, ma muli o kāna mau waiwai kūikawā. I nā huahana meaʻai, lawelawe ka sodium CMC ma ke ʻano he mea mānoanoa, stabilizer, a me ka emulsifier, e hoʻomaikaʻi ana i ke ʻano, ke kūlike, a me ke ola ʻana. I loko o nā lāʻau lapaʻau, hoʻohana ʻia ia ma ke ʻano he binder, disintegrant, a me ka viscosity modifier i nā papa, suspensions, a me nā ʻaila. I loko o nā huahana mālama pilikino, hana ia ma ke ʻano he mānoanoa, moisturizer, a me ka mea hana kiʻiʻoniʻoni i nā mea hoʻonaninani, nā lotions, a me nā niho niho. Ma nā ʻoihana ʻenehana, hoʻohana ʻia ka sodium CMC ma ke ʻano he mea hoʻopaʻa, rheology modifier, a me ka mea hoʻomalu poho wai i loko o nā pena, nā mea hoʻomaʻemaʻe, nā textiles, a me nā wai wili ʻaila.

ʻOi aku ka Sodium CMC ma mua o nā ʻano CMC ʻē aʻe (e like me ka calcium CMC a i ʻole ka potassium CMC) ma muli o kona kiʻekiʻe solubility a paʻa i nā ʻano wai. Loaʻa ia ma nā māka like ʻole a me nā viscosities e kūpono i nā noi like ʻole a me nā koi hoʻoili. Ma ka holoʻokoʻa, ʻo ka sodium CMC kahi mea hoʻohui a hoʻohana nui ʻia me nā noi he nui ma nā ʻoihana like ʻole.
