CMC Carboxymethyl Cellulose

ʻO ka wehewehe pōkole:

CAS: 9004-32-4

ʻO Carboxymethyl Cellulose (CMC) kahi polymer hiki ke hoʻoheheʻe i ka wai anionic i loaʻa mai ka polymer nui loa o ka honua - cotton cellulose.ʻO nā hui carboxymethyl i hoʻopaʻa ʻia (-CH2-COOH) ma ke kaulahao polymer e hoʻoheheʻe ʻia ka cellulose i ka wai.Ke hoʻoheheʻe ʻia, hoʻonui ia i ka viscosity o nā wai wai, suspensions a me emulsions, a ma ke kiʻekiʻe kiʻekiʻe, hāʻawi ia i ka pseudo-plasticity a i ʻole thixotropy.Ma ke ʻano he polyelectrolyte maoli, hāʻawi ʻo CMC i ka uku ʻili i nā ʻāpana kūʻokoʻa a hiki ke hoʻohana ʻia e hoʻomaikaʻi i ka paʻa o nā colloids aqueous a me nā gels a i ʻole e hoʻoulu i ka agglomeration.Hāʻawi ia i nā waiwai maikaʻi o ka mānoanoa, ka paʻa ʻana o ka wai, ka hana kiʻiʻoniʻoni, rheology a me ka lubricity, i hoʻohana nui ʻia i ka meaʻai, nā huahana mālama pilikino, nā pena ʻenehana, nā seramika, ka ʻaila ʻaila, nā mea kūkulu hale etc.

ʻO ka Carboxymethyl cellulose (CMC) he anionic wai-soluble polymer i loaʻa mai ka cellulose.Loaʻa iā ia nā waiwai mānoanoa, absorption, a me ka mālama ʻana i ka wai, a hoʻohana ʻia i kahi ākea o nā noi e pili ana i nā meaʻai a me nā mea hoʻohui meaʻai, nā mea hoʻonaninani, nā mānoanoa a me nā mea paʻa, nā mea hoʻopaʻa, nā mea hoʻoheheʻe wai, a me nā mea mālama wai.No ka loaʻa ʻana o ka mea mai ka cellulose maoli, hōʻike ia i ka biodegradability lohi a hiki ke hoʻopau ʻia ma hope o ka hoʻohana ʻana, e lilo ia i mea ʻoluʻolu loa.

Ka hoʻoheheʻe ʻia o Carboxymethyl Cellulose (CMC)

ʻO Carboxymethyl Cellulose (CMC) kahi mea hydrophilic maoli a i ka wā e hoʻopuehu ai nā ʻāpana sodium carboxymethyl cellulose i loko o ka wai, e pehu koke ia a hemo.
1. Ma lalo o ke ʻano o ka hoʻoulu ʻana, ʻo ka hoʻohui ʻana i ka sodium cmc me ka mālie e kōkua i ka hoʻolalelale ʻana.
2. Ma lalo o ke kūlana o ka hoʻomehana, hoʻohui i ka sodium cmc dispersedly hiki ke hoʻonui i ka helu dissolution, akā ʻaʻole hiki ke kiʻekiʻe ka mahana wela a kūpono i loko o 50-60 ° C.
3. Inā hoʻohanaʻia ma ka huiʻana me nā mea'ē aʻe, e hui mua i nā mea paʻa a laila e hoʻoheheʻeʻia, a ma kēiaʻano, hiki ke hoʻonuiʻia ka māmā holo.
E hoʻohui i kekahi ʻano mea hoʻoheheʻe kūlohelohe i hiki ʻole ke hoʻoheheʻe me ka sodium cmc akā hiki ke hoʻoheheʻe ʻia me ka wai e like me ka ethanol a me ka glycerin a laila e hoʻoheheʻe ʻia, no laila, hiki ke wikiwiki loa ka wikiwiki o ka hoʻonā.
