Sodium Carboxymethyl Cellulose (CMC)he derivative ia o ka cellulose a me ka mea polymer maoli me nā waiwai maikaʻi loa e like me ka solubility wai, viscosity a me ka mānoanoa. Ma muli o kona biocompatibility maikaʻi, non-toxicity a me ka degradability, hoʻohana nui ʻia ka CMC i ka meaʻai, ka lāʻau lapaʻau, nā kemika o kēlā me kēia lā, ka hana pepa, nā textiles, ka ʻaila ʻaila a me nā ʻoihana ʻē aʻe. Ma ke ʻano he mea koʻikoʻi koʻikoʻi, ʻo ke kūlana maikaʻi o CMC ke kuleana alakaʻi koʻikoʻi ma nā ʻano like ʻole.
1. Nā waiwai kumu o CMC
ʻO ka hana kemika o AnxinCel®CMC e hoʻokomo i nā pūʻulu carboxymethyl (-CH2COOH) i loko o nā molekole cellulose, i loaʻa iā ia ka hoʻoheheʻe wai maikaʻi. ʻO kāna mau waiwai nui:
Ka wai hoʻoheheʻe: Hiki iā CMC ke hana i kahi hopena viscous akaka i ka wai a hoʻohana nui ʻia ma ke ʻano he mānoanoa a i ʻole stabilizer i nā huahana wai like ʻole.
Mānoanoa: He kiʻekiʻe ka viscosity CMC a hiki ke hoʻonui pono i ka kūlike o ka wai a hoʻemi i ka wai o ka wai.
Paʻa: Hōʻike ka CMC i ke kūpaʻa kemika maikaʻi i nā pae pH like ʻole a me nā pae wela.
Biodegradability: ʻO ka CMC kahi mea i loaʻa i ka cellulose kūlohelohe me ka biodegradability maikaʻi a me ka hana kūlohelohe koʻikoʻi.
2. Nā kūlana maikaʻi o CMC
ʻOkoʻa nā kūlana maikaʻi o CMC e like me nā ʻano hana like ʻole a me nā koi hana. ʻO kēia kekahi o nā palena maʻamau o ka maikaʻi.
ʻAno: Pono ka CMC ke keʻokeʻo a i ʻole keʻokeʻo amorphous pauka a i ʻole granules. ʻAʻole pono e ʻike ʻia nā haumia a me nā mea ʻē aʻe.
ʻAʻole ʻoi aku ma mua o 10%. Hoʻopilikia ka nui o ka wai i ka mālama ʻana o CMC a me kāna hana i nā noi.
Viscosity: ʻO ka Viscosity kekahi o nā hōʻailona koʻikoʻi o CMC. Hoʻoholo maʻamau ia ma ke ana ʻana i ka viscosity o kāna hoʻonā wai e ka viscometer. ʻO ke kiʻekiʻe o ka viscosity, ʻoi aku ka ikaika o ka hopena mānoanoa o CMC. Loaʻa i nā ʻokoʻa ʻokoʻa o nā hāʻina CMC nā koi viscosity ʻokoʻa, maʻamau ma waena o 100-1000 mPa·s.
Degree of Substitution (DS value): Degree of Substitution (DS) kekahi o nā hiʻohiʻona nui o CMC. Hōʻike ia i ka helu awelika o nā pani carboxymethyl i kēlā me kēia ʻāpana glucose. ʻO ka maʻamau, pono ka waiwai DS ma waena o 0.6-1.2. ʻO ka haʻahaʻa haʻahaʻa o ka waiwai DS e hoʻopilikia i ka hoʻoheheʻe wai a me ka hopena mānoanoa o CMC.
Acidity a i ʻole pH waiwai: Pono ka pH o ka hopena CMC ma waena o 6-8. Hiki ke hoʻololi i ka waiwai pH haʻahaʻa a kiʻekiʻe paha i ke kūpaʻa a me ka hoʻohana ʻana i ka hopena o CMC.
ʻO ka maʻiʻo lehu: ʻO ka maʻiʻo lehu ka maʻiʻo o nā mea inorganic i CMC, ka mea maʻamau e koi ʻia ʻaʻole ʻoi aku ma mua o 5%. Hiki ke hoʻopilikia i ka solubility o CMC a me ka maikaʻi o ka palapala noi hope loa.
Solubility: Pono e hoʻoheheʻe ʻia ʻo CMC i ka wai ma ka lumi wela e hana ai i kahi hopena ʻālohilohi, hoʻokuʻu ʻia. Hiki ke loaʻa i ka CMC me ka haʻahaʻa haʻahaʻa nā mea haumia ʻole a i ʻole cellulose haʻahaʻa.
Maʻiʻo metala kaumaha: Pono nā mea metala kaumaha ma AnxinCel®CMC e hoʻokō me nā kūlana aupuni a ʻoihana paha. ʻAʻole pono e ʻoi aku ka nui o nā metala kaumaha ma mua o 0.002%.
Nā hōʻailona microbiological: Pono ka CMC e hoʻokō i nā kūlana palena microbial. Ma muli o ka hoʻohana ʻana, ʻo ka CMC meaʻai, ka lāʻau lapaʻau-grade CMC, a me nā mea ʻē aʻe e koi i ka mana ikaika o ka ʻike o nā microorganism ʻino e like me ka bacteria, mold, a me E. coli.
3. Nā kūlana noi o CMC
He ʻokoʻa nā koi ʻokoʻa no ka CMC, no laila pono e hoʻokumu ʻia nā kūlana noi kikoʻī. Loaʻa nā maʻamau no ka hoʻohana maʻamau:
ʻOihana meaʻai: Hoʻohana ʻia ka CMC meaʻai no ka mānoanoa, hoʻokūpaʻa, emulsification, a me nā mea ʻē aʻe, a koi ʻia e hoʻokō i nā kūlana palekana meaʻai, e like me ka non-toxic, harmless, non-allergenic, a maikaʻi ka wai solubility a me ka viscosity. Hiki ke hoʻohana ʻia ka CMC e hōʻemi i ka momona a hoʻomaikaʻi i ka ʻono a me ke ʻano o ka meaʻai.
ʻOihana lāʻau lapaʻau: Ma ke ʻano he excipient lāʻau lapaʻau maʻamau, pono ka CMC pharmaceutical-grade i ka mālama pono ʻana i nā haumia, microbial content, non-toxicity, non-allergenicity, etc.
Nā kemika o kēlā me kēia lā: I loko o nā mea hoʻonaninani, nā mea holoi a me nā mea ʻē aʻe o kēlā me kēia lā, hoʻohana ʻia ʻo CMC ma ke ʻano he mānoanoa, stabilizer, suspending agent, etc.
ʻOihana hana pepa: Hoʻohana ʻia ʻo CMC ma ke ʻano he adhesive, coating agent, etc.
Ka hoʻohana ʻana i ka ʻaila: Hoʻohana ʻia ʻo CMC ma ke ʻano he mea hoʻohui wai i nā wai hoʻoheheʻe ʻaila e hoʻonui i ka viscosity a hoʻonui i ka wai. Loaʻa i ia mau noi nā koi kiʻekiʻe no ka solubility a me ka hiki ke hoʻonui i ka viscosity o CMC.
Me ka ulu mau o ka ʻepekema a me ka ʻenehana,CMC, ma ke ʻano he polymer maoli, e hoʻomau i ka hoʻonui ʻana i kāna mau wahi noi. I ka hoʻokumu ʻana i nā kūlana maikaʻi o nā mea CMC, ma waho aʻe o ka noʻonoʻo ʻana i kāna mau waiwai kino a me nā kemika, pono nō hoʻi e noʻonoʻo pono i kāna noi noi e hōʻoia i hiki ke hoʻokō i nā koi o nā ʻano ʻoihana like ʻole. ʻO ka hoʻokumu ʻana i nā kūlana kikoʻī a maopopo he ala nui ia e hōʻoia ai i ka maikaʻi a me ka hopena noi o nā huahana AnxinCel®CMC, a ʻo ia hoʻi ke kī i ka hoʻomaikaʻi ʻana i ka mākeke hoʻokūkū o nā mea CMC.
