ʻO ke ʻano o ka sodium carboxymethyl cellulose

Methyl celluloseʻO ka maʻamau ka pōkole o ka sodium carboxymethyl cellulose, nona kahi ʻano polyanionic pūhui me ka wai hoʻoheheʻe maikaʻi. I waena o lākou, ʻo ka methyl cellulose ka nui o ka methyl cellulose m450, ka methyl cellulose i hoʻololi ʻia, ka meaʻai Grade methyl cellulose, hydroxymethyl cellulose, a me nā mea ʻē aʻe, i hoʻohana pinepine ʻia i nā ʻoihana he nui, hoʻohana nui ʻia i ke kūkulu ʻana, keramika, nā meaʻai, nā pā, ka hana pepa, nā uhi, nā lāʻau lapaʻau, mining, ʻoihana ʻaila a me nā mea ʻē aʻe. He mea kūpono ke ʻōlelo ʻia ma ke kahua o ka sima, ʻike ʻia ka methylcellulose i ka hopena hoʻopaneʻe i nā hui mortar, ʻo ia hoʻi ma muli o ke ʻano kū hoʻokahi o ka methylcellulose.

E like me ka lōʻihi-chain pani cellulose, ka sodium carboxymethylcellulose ia iho ma kahi o 27% ~ 32% o kona hydroxyl pūʻulu i loko o ke ano o methoxy pūʻulu, a me ka degere o ka polymerization o ka like 'ole o nā māka o.ka sodium carboxymethylcelluloseʻokoʻa nō hoʻi. ʻO ke kaumaha o ka molecular e pili nui ana mai 10,000 a 220,000 Da, a ʻo ke ʻano nui o ka hoʻololi ʻana ʻo ia ka helu awelika o nā pūʻulu methoxy, he mau ʻāpana anhydroglucose like ʻole i pili i ke kaulahao.

Hoʻohana nui ʻia ʻo Sodium carboxymethyl cellulose i kēia manawa i kekahi mau hoʻomākaukau topical, a me nā mea hoʻonaninani a me ka meaʻai-grade methyl cellulose, ka mea maʻamau ʻaʻohe mea ʻawaʻawa, non-sensitizing, a me ka hoʻonāukiuki ʻole. ʻO ka Methyl cellulose Su he mea caloric ʻole,
