ʻO ke ʻano o ka sodium carboxymethyl cellulose

Methyl celluloseʻO ka pōkole maʻamau o ka sodium carboxymethyl cellulose, nona kahi ʻano hui polyanionic me ka solubility wai maikaʻi. I waena o lākou, ʻo ka methyl cellulose ka mea nui e komo pū me ka methyl cellulose m450, ka methyl cellulose i hoʻololi ʻia, ka methyl cellulose papa meaʻai, ka hydroxymethyl cellulose, a me nā mea ʻē aʻe, e hoʻohana pinepine ʻia i nā ʻano ʻoihana like ʻole, i hoʻohana nui ʻia i ke kūkulu ʻana, nā keramika, ka meaʻai, nā pila, ka hana pepa, nā uhi, nā lāʻau lapaʻau, ka mining, ka ʻeli ʻaila a me nā ʻoihana ʻē aʻe. He mea kūpono ke haʻi ʻana ma ke kahua o ka sima, he hopena hoʻomaha maopopo ka methylcellulose i nā hui mortar, a ma muli nō hoʻi o ke ʻano kū hoʻokahi o ka methylcellulose.

Ma ke ʻano he cellulose i pani ʻia me ke kaulahao lōʻihi, ʻo ka sodium carboxymethylcellulose ponoʻī he 27% ~ 32% o kāna mau hui hydroxyl ma ke ʻano o nā hui methoxy, a me ke kekelē o ka polymerization o nā papa like ʻole osodium carboxymethylcelluloseʻokoʻa nō hoʻi. ʻO ke kaumaha molekala i pili nui ʻia mai 10,000 a 220,000 Da, a ʻo ke kekelē nui o ka pani ʻana ʻo ia ka helu awelika o nā hui methoxy, ʻo ia hoʻi nā ʻāpana anhydroglucose like ʻole i hoʻopili ʻia i ke kaulahao.

Hoʻohana nui ʻia ka sodium carboxymethyl cellulose i kēia manawa i kekahi mau hoʻomākaukau topical, a me nā mea hoʻonani a me ka methyl cellulose papa meaʻai, ʻo ia hoʻi nā mea ʻawahia ʻole, ʻaʻole hoʻonāukiuki, a ʻaʻole hoʻonāukiuki. ʻO ka Methyl cellulose Su kahi mea ʻaʻohe calorie,
