Carboxymethyl cellulose (CMC)he anionic cellulose ether i hana ʻia e ka hoʻololi kemika o cellulose. Hoʻohana nui ʻia ia i ka meaʻai, ka lāʻau lapaʻau, nā kemika o kēlā me kēia lā, ka ʻaila, ka hana pepa a me nā ʻoihana ʻē aʻe ma muli o kona mānoanoa maikaʻi, hana kiʻiʻoniʻoni, emulsifying, suspending a me ka moisturizing waiwai. He mau māka ʻokoʻa ko CMC. Wahi a ka maʻemaʻe, degere o ka hoʻololi ʻana (DS), viscosity a me nā hiʻohiʻona pili, hiki ke hoʻokaʻawale ʻia nā māka maʻamau i ka pae ʻenehana, ka papa meaʻai a me ka papa lāʻau lapaʻau.
1. ʻOihana carboxymethyl cellulose
ʻO ka papa hana CMC kahi huahana maʻamau i hoʻohana nui ʻia i nā kula ʻoihana. Hoʻohana nui ʻia ia i nā māla aila, hana pepa, keramika, textiles, paʻi ʻana a me nā ʻoihana ʻē aʻe, ʻoi aku ka maikaʻi ma ka mālama ʻana i ka lepo i ka ʻili ʻaila a me ka mea hoʻoikaika i ka hana pepa.
Viscosity: He ākea ka laulā viscosity o ka papa hana CMC, mai ka viscosity haʻahaʻa a hiki i ka viscosity kiʻekiʻe e hoʻokō i nā pono o nā noi like ʻole. Kūpono ka CMC viscosity kiʻekiʻe no ka hoʻohana ʻana ma ke ʻano he mea hoʻopaʻa, ʻoiai ʻo ka viscosity haʻahaʻa kūpono no ka hoʻohana ʻana ma ke ʻano he mānoanoa a me ka stabilizer.
Degree of substitution (DS): He haʻahaʻa ka degere o ka hoʻololi ʻana o ka CMC ʻoihana maʻamau, ma kahi o 0.5-1.2. Hiki ke hoʻonui i ka wikiwiki o ka hoʻoheheʻe ʻana o CMC i ka wai, e ʻae iā ia e hana koke i kahi colloid.
Nā wahi noi:
ʻeli ʻaila:CMChoʻohana ʻia ma ke ʻano he mea mānoanoa a hoʻopaneʻe ʻia i ka ʻeli ʻana i ka lepo e hoʻonui i ka rheology o ka lepo a pale i ka hāʻule ʻana o ka pā luawai.
ʻOihana hana pepa: Hiki ke hoʻohana ʻia ʻo CMC i mea hoʻonui pulp e hoʻomaikaʻi i ka ikaika tensile a me ka pale ʻana o ka pepa.
ʻOihana Ceramic: Hoʻohana ʻia ʻo CMC ma ke ʻano he mānoanoa no nā aniani seramika, hiki ke hoʻomaikaʻi maikaʻi i ka adhesion a me ka maʻalahi o ka glaze a hoʻonui i ka hopena kiʻiʻoniʻoni.
Pōmaikaʻi: He haʻahaʻa ke kumu kūʻai ʻo CMC-ʻoihana a kūpono no ka hana ʻoihana nui.
2. Carboxymethyl cellulose meaʻai
Hoʻohana nui ʻia ka CMC meaʻai i ka ʻoihana meaʻai, ma ke ʻano he mānoanoa, emulsifier, stabilizer, etc. Loaʻa i kēia papa o CMC nā koi kiʻekiʻe no ka maʻemaʻe, nā kūlana maʻemaʻe a me ka palekana.
Viscosity: ʻO ka viscosity o ka CMC meaʻai maʻamau ka haʻahaʻa a i ka waena, kaohi ma waena o 300-3000mPa·s. E koho ʻia ka viscosity kikoʻī e like me ke ʻano o ka noi a me nā pono huahana.
Degree of substitution (DS): ʻO ke kiʻekiʻe o ka hoʻololi ʻana i ka CMC meaʻai maʻamau ka mālama ʻia ma waena o 0.65-0.85, hiki ke hāʻawi i ka viscosity haʻahaʻa a me ka solubility maikaʻi.
Nā wahi noi:
Nā huahana waiu: Hoʻohana ʻia ʻo CMC i nā huahana waiū e like me ka ice cream a me ka yogurt e hoʻonui i ka viscosity a me ka ʻono o ka huahana.
Nā mea inu: I loko o ka wai a me nā mea inu kī, hiki iā CMC ke hana ma ke ʻano he mea hoʻomaha hoʻomaha e pale ai i ka pulp mai ka hoʻopaʻa ʻana.
Noodles: I loko o nā noodles a me nā noodles, hiki i ka CMC ke hoʻonui i ka paʻakikī a me ka ʻono o nā noodles, e hoʻonui ai i ka elastic.
Nā mea ʻono: I loko o nā kīʻaha a me nā ʻaʻahu salakeke, hana ʻo CMC ma ke ʻano he mānoanoa a me ka emulsifier e pale ai i ka hoʻokaʻawale ʻana i ka ʻaila-wai a hoʻolōʻihi i ke ola.
Pōmaikaʻi: Kūlike ka CMC meaʻai i nā kūlana hoʻomaʻemaʻe meaʻai, ʻaʻohe pōʻino i ke kino o ke kanaka, hiki ke hoʻoheheʻe ʻia i ka wai anuanu a hiki ke hana koke i nā colloids, a loaʻa i nā hopena mānoanoa maikaʻi loa.
3. ʻO ka carboxymethyl cellulose lāʻau lapaʻau
Lapaʻau-papaCMCkoi i nā kūlana maʻemaʻe a me ka palekana a hoʻohana nui ʻia i ka hana lāʻau lapaʻau a me nā mea lapaʻau. Pono kēia papa o CMC e hoʻokō i nā kūlana pharmacopoeia a e hoʻopaʻa i ka mana maikaʻi e hōʻoia i ka mea ʻawaʻawa a ʻaʻole hoʻonāukiuki.
Viscosity: ʻOi aku ka hoʻomaʻemaʻe ʻia o ka laulā viscosity o ka lāʻau lapaʻau-grade CMC, maʻamau ma waena o 400-1500mPa·s, i mea e hōʻoia ai i kona hoʻomalu a paʻa i nā noi lāʻau lapaʻau a me nā lāʻau lapaʻau.
Degree of substitution (DS): ʻO ke degere o ka hoʻololi ʻana i ka papa lāʻau lapaʻau ma waena o 0.7-1.2 e hāʻawi i ka solubility kūpono a me ka paʻa.
Nā wahi noi:
ʻO ka hoʻomākaukau ʻana i ka lāʻau lapaʻau: CMC hana ma ke ʻano he mea hoʻopaʻa a disintegrant no nā papa, hiki ke hoʻonui i ka paʻakikī a me ka paʻa o nā papa, a hiki ke hoʻopau koke i ke kino.
ʻO nā kulu maka: Hana ʻo CMC ma ke ʻano he mānoanoa a me ka moisturizer no nā lāʻau lapaʻau ophthalmic, hiki ke hoʻohālikelike i nā waiwai o ka waimaka, kōkua i ka lubricate i nā maka, a hoʻomaha i nā hōʻailona maka maloʻo.
Kaʻaʻahu ʻeha: Hiki ke hana ʻia ʻo CMC i kiʻi ʻoniʻoni a me nā lole e like me ka gel no ka mālama ʻana i ka ʻeha, me ka paʻa ʻana o ka makū a me ka hanu maikaʻi, e hāpai ana i ka hoʻōla ʻana i ka ʻeha.
Pōmaikaʻi: Hoʻokō ka CMC papa lāʻau lapaʻau i nā kūlana pharmacopoeia, he kiʻekiʻe biocompatibility a me ka palekana, a kūpono no ka waha, injection a me nā ʻano hoʻokele ʻē aʻe.
4. Nā māka kūikawā o carboxymethyl cellulose
Ma waho aʻe o nā papa ʻekolu i luna, hiki ke hoʻopili ʻia ʻo CMC e like me nā pono kikoʻī o nā kahua like ʻole, e like me ka cosmetic grade CMC, toothpaste grade CMC, etc.
Cosmetic grade CMC: hoʻohana ʻia i nā huahana mālama ʻili, nā maka maka, a me nā mea ʻē aʻe, me ka hana kiʻiʻoniʻoni maikaʻi a me ka paʻa mau.
ʻO ka papa niho niho CMC: hoʻohana ʻia e like me ka mānoanoa a me ka hoʻopili ʻana e hāʻawi i ka toothpaste i kahi ʻano pāpaʻi maikaʻi aʻe.
Carboxymethyl celluloseloaʻa i ka laulā o nā noi a me nā ʻano koho papa. Loaʻa i kēlā me kēia papa nā waiwai kino a me nā kemika e hoʻokō i nā pono o nā ʻoihana like ʻole.
