Carboxymethyl Cellulose (CMC)he hui polymer hiki ke hoʻoheheʻe ʻia i ka wai i hana ʻia e ka hoʻololi kemika o cellulose maoli. Hoʻohana nui ʻia ia i nā huahana kemika i kēlā me kēia lā. Ma keʻano he mānoanoa maʻamau, stabilizer a suspending agent, CMC noho i kahi kūlana koʻikoʻi i kēlā me kēia lā nā huahana kemika e like me nā huahana mālama ʻili, toothpaste, detergents, etc.
1. Nā waiwai kemika o ka carboxymethyl cellulose
Hoʻokumu ʻia ka CMC e ka hopena o ka cellulose maoli me ka sodium chloroacetate (a i ʻole chloroacetic acid) i loko o kahi ʻano alkaline. ʻO kona ʻano molekala ka nui o ka pūʻulu cellulose a me nā hui carboxymethyl (-CH₂-COOH), a ʻo ka hoʻokomo ʻana i kēia mau pūʻulu hāʻawi iā CMC hydrophilicity. ʻO ke kaumaha o ka molekala a me ke degere o ka hoʻololi ʻana o CMC (ʻo ia hoʻi, ʻo ka carboxymethyl substitution rate ma ka cellulose mole) nā ʻāpana koʻikoʻi e pili ana i kona solubility a me ka hopena mānoanoa. I ka hoʻokumu ʻana i nā huahana kemika i kēlā me kēia lā, ʻike pinepine ʻia ʻo CMC ma ke ʻano he pauka keʻokeʻo a melemele liʻiliʻi me ka hoʻoheheʻe wai maikaʻi a me nā waiwai mānoanoa.
2. Nā waiwai hana o carboxymethyl cellulose
Hāʻawi nā waiwai physicochemical o CMC iā ia i nā hana he nui i nā huahana kemika i kēlā me kēia lā:
Hana mānoanoa: Hōʻike ʻo CMC i ka hopena mānoanoa i loko o ka wai wai, a hiki ke hoʻololi ʻia ka viscosity o ka hoʻonā ʻana me ka noʻonoʻo, ke kaumaha molekala a me ke degere o ka hoʻololi ʻana o CMC. ʻO ka hoʻohui ʻana i ka CMC i nā huahana kemika i kēlā me kēia lā i kahi nui kūpono hiki ke hoʻonui i ka viscosity o ka huahana, lawe mai i kahi ʻike mea hoʻohana ʻoi aku ka maikaʻi, a pale pū i ka huahana mai ka stratification a i ʻole ka nalowale.
Mea hoʻopaʻa a hoʻopaneʻe: ʻO ka hui carboxyl i loko o ka molecular structure o CMC hiki ke hana i nā paʻa hydrogen me nā mole wai a loaʻa iā ia ka hoʻoheheʻe wai maikaʻi a me ka pili. Hiki i ka CMC ke hana i ka ʻōnaehana hoʻokuʻu like ʻole i ka hāʻina, e kōkua ai i ka hoʻopaʻa ʻana i nā ʻāpana insoluble a i ʻole nā ʻaila hinu i loko o ka huahana a pale i ka ua a i ʻole stratification. He mea koʻikoʻi kēia waiwai i nā mea hoʻomaʻemaʻe a me nā huahana mālama ʻili emulsified i loaʻa nā mea ʻala.
ʻO ka waiwai hana kiʻiʻoniʻoni: Loaʻa i ka CMC kahi waiwai kiʻiʻoniʻoni maikaʻi loa, e hana ana i kahi kiʻiʻoniʻoni pale ma ka ʻili o ka ʻili a i ʻole nā niho, hiki ke hōʻemi i ka evaporation wai a hoʻonui i ka hopena moisturizing o ka huahana. Hoʻohana nui ʻia kēia waiwai i nā huahana mālama ʻili a me nā huahana mālama waha.
Lubricity: Ma nā huahana kemika i kēlā me kēia lā e like me ka toothpaste a me ka shaving foam, hiki iā CMC ke hāʻawi i ka lubricity maikaʻi, kōkua i ka hoʻomaikaʻi ʻana i ka maʻalahi o ka huahana, hoʻemi i ka friction, a pēlā e hoʻonui ai i ka ʻike mea hoʻohana.
3. Hoʻohana i ka carboxymethyl cellulose i nā huahana kemika i kēlā me kēia lā
ʻO nā waiwai like ʻole o CMC e lilo ia i mea waiwai nui i nā huahana kemika i kēlā me kēia lā. ʻO ia nā mea kikoʻī i nā huahana like ʻole:
3.1 Pahu niho
ʻO ka niho niho kahi hiʻohiʻona maʻamau o ka noi CMC i nā huahana kemika i kēlā me kēia lā. Hoʻohana nui ʻia ʻo CMC ma ke ʻano he mānoanoa a me ka stabilizer i ka toothpaste. No ka mea e koi ana ka toothpaste i kekahi viscosity e hōʻoia i ka hoʻomaʻemaʻe maikaʻi a me ka hōʻoluʻolu i ka wā e palaki ai i nā niho, hiki i ka hoʻohui ʻana o CMC ke hoʻonui i ka viscosity o ka toothpaste, i ʻole e lahilahi ke pili i ka pulupulu niho, ʻaʻole i mānoanoa e hoʻopili i ka extrusion. Hiki nō hoʻi iā CMC ke kōkua i ka hoʻokuʻu ʻana i kekahi mau mea hiki ʻole ke hoʻoheheʻe ʻia e like me nā abrasives i loko o ka toothpaste e hoʻopaʻa paʻa i ke ʻano o ka toothpaste. Eia kekahi, ʻo ka waiwai hana kiʻiʻoniʻoni o CMC hiki iā ia ke hana i kahi pale pale ma ka ʻili o nā niho, e hoʻonui i ka hopena hoʻomaʻemaʻe o ka waha waha.
3.2 Nā mea holoi
He koʻikoʻi ka hana a CMC i nā mea holoi. Nui nā wai hoʻomaʻemaʻe wai a me nā wai holoi kīʻaha i loko o nā ʻāpana hiki ʻole ke hoʻoheheʻe ʻia a me nā surfactants, hiki ke maʻalahi i ka stratification i ka wā mālama. ʻO CMC, ma ke ʻano he mea hoʻomaha a me ka mānoanoa, hiki ke hoʻokuʻu pono i nā ʻāpana, hoʻopaʻa i ke ʻano o ka huahana, a pale i ka stratification. Eia kekahi, hiki i ka CMC ke hāʻawi i kahi lubrication i ka wā e hoʻohana ai a hōʻemi i ka ʻeha o ka ʻili, ʻoi aku hoʻi i ka mea holoi lole a me ka kopa lima.
3.3 Nā huahana mālama ʻili
I nā huahana mālama ʻili, hoʻohana nui ʻia ʻo CMC ma ke ʻano he mānoanoa a me ka moisturizer. No ka laʻana, i nā huahana e like me nā lotions, nā ʻaila a me nā essences, hiki i ka CMC ke hoʻonui i ka viscosity o ka huahana a lawe mai i kahi manaʻo maʻalahi o ka hoʻohana. ʻO nā mea hana kiʻiʻoniʻoni o CMC hiki iā ia ke hana i kahi kiʻiʻoniʻoni pale ma ka ʻili o ka ʻili e pale ai i ka hoʻoheheʻe ʻana o ka wai a hoʻonui i ka hopena moisturizing o ka huahana, a laila e hoʻokō ai i ke kumu o ka moisturizing lōʻihi. Eia kekahi, he palekana kiʻekiʻe ka CMC a kūpono i ka ʻili koʻikoʻi a me nā ʻano ʻili like ʻole.
3.4 Ka huʻa a me nā huahana ʻauʻau
I ka huʻa a me nā huahana ʻauʻau,CMChiki ke pāʻani i kahi hana lubricating, hoʻonui i ka maʻalahi o ka huahana, a hoʻemi i ka friction ʻili. Hiki i ka hopena mānoanoa o CMC ke hoʻonui i ka paʻa o ka ʻūhā, e hoʻomāmā a paʻa i ka huʻa, e lawe mai i kahi ʻoi aku ka maikaʻi o ka ʻauʻau ʻana. Eia kekahi, hiki i ka waiwai hana kiʻiʻoniʻoni o CMC ke hana i kahi pale pale ma ka ʻili, e hōʻemi ana i ka huhū o waho, kūpono loa no ka ʻili paʻakikī.
4. Ka palekana a me ka hoʻomau o ka carboxymethyl cellulose
Loaʻa ʻia ʻo CMC mai ka cellulose kūlohelohe a he kiʻekiʻe biodegradability. ʻAʻole ia e hoʻomau i ka hoʻohaumia ʻana i ke kaiapuni i ka wā e hoʻohana ai, e kū ana i nā koi o ka hoʻomohala hoʻomau. Ua hōʻike ʻia ʻo CMC he palekana no ka hoʻohana kanaka. Ua ʻae ʻia ʻo CMC ma ke ʻano he meaʻai meaʻai ma nā ʻāina he nui, e hōʻike ana he haʻahaʻa haʻahaʻa ia i ke kino kanaka. ʻO ka ʻike CMC i nā huahana kemika i kēlā me kēia lā he haʻahaʻa. Ma hope o nā hoʻokolohua lapaʻau he nui, ʻaʻole e hoʻonāukiuki ka CMC i ka ʻili a i ʻole ka waha waha, no laila kūpono ia i nā ʻano kanaka āpau.
ʻO ka hoʻohana ākea ocarboxymethyl cellulose (CMC)i nā huahana kemika i kēlā me kēia lā e hōʻoia i kāna hana maikaʻi loa a me ka versatility. Ma keʻano he mānoanoa palekana, maikaʻi a hoʻomau, suspending agent a lubricant, CMC pāʻani i ka hana koʻikoʻi i nā ʻano huahana kemika o kēlā me kēia lā e like me nā huahana mālama ʻili, toothpaste, detergents, etc. ka paʻa a me ka hopena o ka huahana. Eia kekahi, ʻo ka CMC's environment friendliness and biodegradability e hoʻokō i ka koi o ke kaiāulu o kēia wā no nā mea kūlohelohe. No laila, ke piʻi aʻe nei ka makemake o nā mea kūʻai aku no nā huahana kiʻekiʻe, palekana, a me nā mea e pili ana i ke kaiapuni, e ʻoi aku ka laulā o nā noi noi o CMC i ka ʻoihana kemika i kēlā me kēia lā.
