Carboxymethyl Cellulose
ʻAno:keʻokeʻo a i ʻole ka waiu pauka keʻokeʻo
Nā ʻano kino:he mea ia he cellulose me nā hui carboxymethyl (-CH2-COOH) i hoʻopaʻa ʻia i kekahi o nā pūʻulu hydroxyl o nā monomers glucopyranose i hana i ka iwi kuamoʻo cellulose.Ua kapa ʻia ʻo ia ʻo CMC, Carboxymethyl.Cellulose Sodium, Sodium paʻakai o Caboxy Methyl Cellulose.ʻO CMC kekahi o ka polyelectrolyte solube wai nui.Hiki ke hoʻoheheʻe ʻia i ka wai, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka waiʻona, ethanol, benzene, chloroform a me nā mea hoʻoheheʻe ʻē aʻe.Kūleʻa i nā aila holoholona a me nā mea kanu a ʻaʻole i hana ʻia e ka mālamalama.

Palapala noi: ʻO CMC (kapa ʻia ʻo "industril gourmet powder") kahi ʻano o ka cellulose ether i loko o ka wai-soluble fiber derivative, kahi i hoʻohana nui ʻia no nā ʻoihana o ka hoʻoili ʻana i ka meaʻai, ka wai lactic acid a me ka toothpaste, etc., a he hana koʻikoʻi. i kēlā me kēia ʻoihana a i ʻole kālepa e like me ka emulsifier, ka mea hoʻonui nui .stabilizer, thickener, retarder, film former, dispersing agent, suspending agent, adhisive, mercerizing agent, lustering agent a me ka waihoʻoluʻu kala, etc. .
