Solubility CMC

ʻO ka sodium carboxymethyl cellulose (CMC) he mea hiki ke hoʻoheheʻe ʻia i ka wai, ʻo ia kekahi o kāna mau waiwai koʻikoʻi a kōkua i kona hoʻohana ākea ʻana i nā ʻoihana like ʻole. Ke hoʻopuehu ʻia i loko o ka wai, hana ʻo CMC i nā hopena viscous a i ʻole nā ​​gels, e pili ana i ka paona a me ke kaumaha molekala o ka CMC.

Hoʻopili ʻia ka solubility o CMC i ka wai e kekahi mau kumu:

1. Degree of Substitution (DS): ʻO ka CMC me nā koina DS kiʻekiʻe e ʻoi aku ka nui o ka hoʻoheheʻe wai ma muli o ka nui o nā hui carboxymethyl i hoʻokomo ʻia i ka iwi kuamoʻo cellulose.
2. Kaumaha Molekala: ʻOi aku ka nui o ke kaumaha molekala CMC e hōʻike ana i ka lohi o ka hoʻoheheʻe ʻana i ka hoʻohālikelike ʻia me nā māka haʻahaʻa haʻahaʻa. Eia nō naʻe, i ka wā i hoʻoheheʻe ʻia, hana maʻamau ʻo CMC kiʻekiʻe a haʻahaʻa hoʻi i nā haʻina me nā waiwai viscosity like.
3. Mahana: ʻO ka maʻamau, piʻi ka solubility o CMC i ka wai me ka mahana. ʻO nā mahana kiʻekiʻe e hoʻomaʻamaʻa i ke kaʻina hoʻoheheʻe a hopena i ka hydration wikiwiki o nā ʻāpana CMC.
4. pH: ʻAʻole pili ka solubility o CMC i ka pH i loko o ka laulā maʻamau i loaʻa i ka hapa nui o nā noi. Paʻa a hiki ke hoʻoheheʻe ʻia nā hopena CMC ma luna o kahi ākea pH ākea, mai ka acidic a i ka alkaline.
5. ʻO ka hoʻonāukiuki: ʻO ka hoʻouluʻana a iʻole ka huiʻana e hoʻonui i ka hoʻoheheʻeʻana o CMC i ka wai ma o ka hoʻonuiʻana i ka pilina ma waena o nā'āpana CMC a me nā mole wai, pēlā e hoʻonui ai i ka hana hydration.

ʻO ka sodium carboxymethyl cellulose (CMC) ka mea i ʻike ʻia no kona hoʻoheheʻe wai maikaʻi loa, e lilo ia i mea hoʻohui waiwai i ka nui o nā noi, ʻo ia hoʻi ka meaʻai, nā lāʻau lapaʻau, nā huahana mālama pilikino, a me nā hana ʻenehana. ʻO kona hiki ke hana i nā hopena paʻa a viscous e kōkua i kāna hana ma ke ʻano he mānoanoa, stabilizer, binder, a me nā kiʻiʻoniʻoni-mua i nā huahana a me nā kaʻina hana.
