ʻO CMC (sodium carboxymethyl cellulose) a me HPMC (hydroxypropyl methyl cellulose) ʻelua mau mea hoʻohana maʻamau cellulose, i hoʻohana nui ʻia i nā ʻoihana like ʻole. No ka mea ʻoi aku ka maikaʻi, pili ia i ke ʻano kikoʻī noiʻi a me nā pono.
1. Waiwai kemika
ʻO CMC kahi mea hoʻohui wai-soluble polymer anionic i loaʻa ma ka mālama ʻana i ka cellulose kūlohelohe me ka sodium chloroacetate ma lalo o nā kūlana alkaline. Hoʻokomo ʻia nā pūʻulu Carboxymethyl i loko o kāna kaulahao molekala, kahi e loaʻa ai iā ia ka solubility wai maikaʻi a me nā waiwai mānoanoa.
HPMC mea he non-ionic cellulose ether i loaa ma ka reacting cellulose me methyl chloride a propylene oxide. ʻO nā pūʻulu methoxy a me hydroxypropoxy i loko o ka molecular structure o HPMC e hāʻawi iā ia i ka mānoanoa maikaʻi, kūpaʻa a me ka paʻa wai, a me nā waiwai gel thermal maikaʻi.
2. Nā kahua noi
ʻOihana meaʻai: Hoʻohana pinepine ʻia ʻo CMC i ka meaʻai ma ke ʻano he mānoanoa, stabilizer, suspending agent a me emulsifier, etc., a loaʻa maʻamau i ka yogurt, ice cream, jelly, nā mea inu a me nā huahana bakena. Hiki iā ia ke hoʻonui i ke ʻano o ka meaʻai a hoʻonui i ke ola o ka papa. ʻOiai ua hoʻohana ʻia ʻo HPMC i ka ʻoihana meaʻai, hoʻohana nui ʻia ia ma ke ʻano he mea hoʻohui i ka fiber meaʻai, ʻoi aku hoʻi i kekahi mau huahana gluten-free.
ʻOihana Lapaʻau: Hoʻohana nui ʻia ʻo HPMC i ka ʻoihana lāʻau lapaʻau, ʻoi aku hoʻi i ka uhi papa, nā lāʻau hoʻokuʻu hoʻokuʻu ʻia a me ka hana capsule. ʻO kāna mau waiwai non-ionic a me ka biocompatibility maikaʻi e hāʻawi iā ia i nā pono kūʻokoʻa i nā ʻōnaehana lawe lāʻau. Hoʻohana pū ʻia ʻo CMC i ka ʻoihana lāʻau lapaʻau, akā ʻoi aku ka nui o ka mānoanoa a me ka hoʻopili ʻana i nā lāʻau lapaʻau.
ʻOihana hana a me nā uhi: Hoʻohana nui ʻia ʻo HPMC i nā mea kūkulu hale, ʻoi aku hoʻi i ka mortar maloʻo, gypsum, a me ka pauka putty, no ka maikaʻi o ka paʻa ʻana o ka wai, ka mānoanoa a me nā waiwai anti-slip. Loaʻa iā CMC kekahi mau noi i ka ʻoihana uhi, akā ʻoi aku ka maʻamau i hoʻohana ʻia ma ke ʻano he mānoanoa no nā uhi wai.
ʻO nā mea hoʻonani a me ka mālama pilikino: Hoʻohana pinepine ʻia ka HPMC i nā mea hoʻonaninani, ʻoi aku hoʻi i loko o nā lotions, creams, shampoos a me toothpastes, ma ke ʻano he mānoanoa, emulsion stabilizer a me ka moisturizer. Hoʻohana ʻia ʻo CMC i nā noi like, akā ʻaʻole maikaʻi kona hopena moisturizing e like me HPMC.
3. Nā hiʻohiʻona hana
Hiki ke hoʻoheheʻe ʻia ka wai: CMC hiki ke hoʻoheheʻe maikaʻi ʻia i ka wai anuanu a me ka wai wela, ʻoiai ʻo HPMC hiki ke hoʻoheheʻe ʻia i ka wai anuanu, akā ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai wela a loaʻa i ka gelation thermal. No laila, ʻoi aku ka maikaʻi o ka HPMC no nā huahana e koi ana i nā waiwai gelation thermal i kekahi mau noi, e like me nā papa hoʻokuʻu hoʻokuʻu ʻia i ka lāʻau lapaʻau.
ʻO ka mana viscosity: He haʻahaʻa haʻahaʻa ko CMC a he maʻalahi ke hoʻomalu, ʻoiai he ākea ākea ka HPMC a ʻoi aku ka maʻalahi. Hiki i ka HPMC ke hāʻawi i ka viscosity kiʻekiʻe a paʻa mau i nā mahana like ʻole, e ʻoi aku ka maikaʻi ma nā noi e koi ana i ka mana viscosity pololei.
Paʻa: ʻoi aku ka maikaʻi o ka HPMC ma mua o CMC. Hōʻike ia i ke kūpaʻa maikaʻi i nā kaiapuni ʻakika a i ʻole ka alkaline, ʻoiai ʻo CMC hiki ke hoʻohaʻahaʻa i nā ʻakika ikaika a i ʻole nā kumu ikaika.
4. Kumukuai a me ke kumu kuai
Ma keʻano laulā, ʻoi aku ka liʻiliʻi o CMC a kūpono i nā noi ʻoihana nui, ʻoiai ʻo HPMC ke kumu kūʻai ma muli o kāna kaʻina hana paʻakikī a me ke kumukūʻai kiʻekiʻe. ʻOi aku ka maikaʻi o ka CMC i nā kūlana i makemake ʻia nā mea nui a paʻakikī ke kumukūʻai. Eia nō naʻe, ma kekahi mau kula me nā koi hana kiʻekiʻe, e like me ka lāʻau lapaʻau a me nā mea hoʻonaninani kiʻekiʻe, hoʻohana nui ʻia ʻo HPMC ma muli o kāna mau pono hana kūikawā ʻoiai ke kumu kūʻai kiʻekiʻe.
5. Ka palekana a me ka palekana
Loaʻa i ka CMC a me ka HPMC ka biodegradability maikaʻi a me ka pale ʻana i ke kaiapuni, a he liʻiliʻi ka hopena i ke kaiapuni i ka wā e hoʻohana ai. Manaʻo ʻia nā meaʻai palekana a me nā mea hoʻohui lāʻau, a hiki ke hoʻohana pono ʻia i nā huahana like ʻole ma hope o ka nānā pono ʻana a me ka hōʻoia.
Loaʻa iā CMC a me HPMC ko lākou pono ponoʻī a me nā hemahema, a ʻaʻole hiki ke haʻi wale i ka mea ʻoi aku ka maikaʻi. No nā noi e koi ana i nā kumu kūʻai haʻahaʻa, hana nui, e like me ka ʻoihana meaʻai maʻamau a me nā pono mānoanoa maʻalahi, ʻo CMC kahi koho kūpono. Ma nā kula me nā koi hana kiʻekiʻe, e like me nā ʻōnaehana hoʻokuʻu i ka lāʻau lapaʻau, nā mea kūkulu hale kiʻekiʻe a me nā mea hoʻonaninani kiʻekiʻe, kūpono paha ka HPMC ma muli o kāna hana maikaʻi loa. No laila, ʻo ke koho ʻana o ka cellulose derivative e pili ana i nā koi noi kikoʻī, nā koi hana a me nā noʻonoʻo kumukūʻai.
