ʻO ka sodium carboxymethyl cellulose structure

Hoʻolauna

ʻO Carboxymethyl cellulose (CMC) kahi ʻano o ka cellulose derivative i loaʻa mai ka cellulose e ka carboxymethylation. He pauka keʻokeʻo, ʻala ʻole, ʻono ʻole i hoʻohana nui ʻia i ka meaʻai, nā lāʻau lapaʻau, nā mea hoʻonaninani, a me nā ʻoihana ʻē aʻe. ʻO CMC kahi polymer hiki ke hoʻoheheʻe ʻia i ka wai i loaʻa ka nui o ka hoʻohana ʻana ma muli o kāna mau ʻano ʻokoʻa. Hoʻohana ʻia ʻo ia ma ke ʻano he mea mānoanoa, stabilizer, emulsifier, a me ka mea hoʻomaha. Hoʻohana ʻia ʻo CMC ma ke ʻano he colloid pale i ka hana ʻana i ka pepa a me nā textiles.

Kapili

Hoʻokumu ʻia ke ʻano o ka carboxymethyl cellulose (CMC) i kahi kaulahao laina o nā molekole glucose i hoʻopili pū ʻia e nā paʻa glycosidic. Hoʻopili ʻia nā molekole glucose i kekahi i kekahi e ka atom oxygen hoʻokahi, e hana ana i kahi kaulahao laina. ʻO ke kaulahao laina ka carboxymethylated, ʻo ia hoʻi, ua hoʻopili ʻia kahi hui carboxymethyl (CH2COOH) i ka hui hydroxyl (OH) o ka mole glucose. ʻO kēia kaʻina hana carboxymethylation ka hopena i kahi mole carboxymethyl cellulose i hoʻopiʻi ʻia.

Hiki ke hōʻike ʻia ke ʻano o ka carboxymethyl cellulose e kēia ʻano:

(C6H10O5)n-CH2COOH

kahi n ka degere o ka pani (DS) o ka hui carboxymethyl. ʻO ke kiʻekiʻe o ka hoʻololi ʻana ʻo ia ka helu o nā pūʻulu carboxymethyl no ka mole glucose. ʻO ke kiʻekiʻe o ka hoʻololi ʻana, ʻoi aku ka kiʻekiʻe o ka viscosity o ka hopena CMC.

Loaʻa iā Carboxymethyl cellulose he mau waiwai kūʻokoʻa e pono ai i nā ʻano hana like ʻole. He polymer hiki ke hoʻoheheʻe ʻia i ka wai i paʻa loa i nā ʻano wai. ʻAʻole ia he mea ʻawaʻawa, ʻaʻole hoʻonāukiuki, a ʻaʻole allergenic. Kūʻē pū ʻo CMC i ka hōʻino ʻana i ka microbial a ʻaʻole pili i ka pH a i ʻole ka mahana. He mea mānoanoa ikaika ʻo CMC a hiki ke hoʻohana ʻia no ka mānoanoa o nā wai like ʻole, me ka meaʻai, nā lāʻau lapaʻau, a me nā mea hoʻonaninani. Hoʻohana ʻia ʻo ia ma ke ʻano he emulsifier, stabilizer, a me ka suspending agent. Hoʻohana ʻia ʻo CMC ma ke ʻano he colloid pale i ka hana ʻana i ka pepa a me nā textiles. ʻO ka hopena ʻO Carboxymethyl cellulose (CMC) kahi ʻano o ka cellulose derivative i loaʻa mai ka cellulose e ka carboxymethylation. He pauka keʻokeʻo, ʻala ʻole, ʻono ʻole i hoʻohana nui ʻia i ka meaʻai, nā lāʻau lapaʻau, nā mea hoʻonaninani, a me nā ʻoihana ʻē aʻe. Hoʻokumu ʻia ʻo CMC i kahi kaulahao laina o nā molekole glucose i hoʻopili ʻia e nā paʻa glycosidic a me ka carboxymethylated. Loaʻa iā ia ka nui o nā waiwai kūʻokoʻa e pono ai i nā ʻano hana like ʻole. ʻO CMC kahi mea mānoanoa ikaika a hiki ke hoʻohana ʻia ma ke ʻano he emulsifier, stabilizer, a me ka mea hoʻomaha. Hoʻohana ʻia ia ma ke ʻano he colloid pale i ka hana ʻana i ka pepa a me nā textiles.
