Kāohi - Sodium Carboxymethyl Cellulose (CMC)

Hiki i ka sodium carboxymethyl cellulose (CMC) ke hana ma ke ʻano he mea pale i nā kaʻina hana ʻenehana ma muli o kona hiki ke hoʻololi i nā waiwai rheological, hoʻomalu i ka viscosity, a hoʻopaʻa i nā formulations. Eia kekahi mau ala e hiki ai i ka CMC ke hana ma ke ʻano he mea paʻa.

1. Kāohi unahi:
   • Ma nā noi hoʻoponopono wai, hiki i ka CMC ke hana ma ke ʻano he mea hoʻopale unahi ma o ka hoʻokaʻawale ʻana i nā ion metala a pale aku iā lākou mai ka hoʻokahe ʻana a me ka hoʻokumu ʻana i nā waihona unahi. Kōkua ʻo CMC i ka pale ʻana i ka hoʻokumu ʻana o ka unahi i nā paipu, boilers, a me nā mea hoʻololi wela, e hōʻemi ana i ka mālama ʻana a me nā koina hana.
2. Kāohi ʻino:
   • Hiki i ka CMC ke hana ma ke ʻano he mea hoʻopaʻa ʻino ma o ka hana ʻana i kahi kiʻiʻoniʻoni pale ma nā ʻili metala, e pale ana i nā mea ʻino mai ke komo ʻana me ka substrate metala. Ke hana nei kēia kiʻiʻoniʻoni ma ke ʻano he pale kūʻē i ka oxidation a me ka hoʻouka kemika, e hoʻolōʻihi i ke ola o nā mea metala a me nā ʻōnaehana.
3. Hoʻopaʻa wai wai:
   • I ka hana ʻaila a me ka hau, hiki i ka CMC ke lawelawe ma ke ʻano he hydrate inhibitor ma ke keakea ʻana i ka hoʻokumu ʻana o nā hydrates kinoea i nā pipeline a me nā mea hana. Ma ka hoʻomalu ʻana i ka ulu a me ka hoʻohui ʻana o nā kristal hydrate, kōkua ʻo CMC i ka pale ʻana i nā poloka a me ka hoʻopiʻi ʻana i nā pilikia ma lalo o ka moana a me nā ʻaoʻao o luna.
4. Emulsion Stabilization:
   • Hana ʻo CMC ma ke ʻano he mea paʻa o ka hoʻokaʻawale ʻana a me ka coalescence i nā emulsions ma ka hana ʻana i kahi papa colloidal pale a puni nā droplets i hoʻopuehu ʻia. Hoʻopaʻa kēia i ka emulsion a pale i ka coalescence o ka aila a i ʻole ka wai, e hōʻoia i ka kūlike a me ka paʻa i nā hana e like me nā pena, nā uhi, a me nā emulsion meaʻai.
5. Kāohi Flocculation:
   • I nā kaʻina hana hoʻomaʻemaʻe wai, hiki i ka CMC ke kāohi i ka flocculation o nā ʻāpana i hoʻokuʻu ʻia ma o ka hoʻopuehu ʻana a me ka hoʻopaʻa ʻana iā lākou i ka pae wai. Mālama kēia i ka hoʻokumu ʻana o nā flocs nui a hoʻomaʻamaʻa i ka hoʻokaʻawale ʻana o nā mea paʻa mai nā kahawai wai, e hoʻomaikaʻi i ka pono o ka wehewehe a me nā kaʻina kānana.
6. Kāohi i ka ulu ʻana o ka kristal:
   • Hiki i ka CMC ke kāohi i ka ulu a me ka hoʻohui ʻana o nā kristal i nā kaʻina hana ʻoihana like ʻole, e like me ka crystallization o nā paʻakai, nā minerala, a i ʻole nā ​​​​hui lāʻau. Ma ke kaohi ʻana i ka nucleation crystal a me ka ulu ʻana, kōkua ʻo CMC i ka hana ʻana i nā huahana crystalline ʻoi aku ka maikaʻi a ʻoi aku ka like me nā puʻupuʻu nui i makemake ʻia.
7. Kāohi i ka ua:
   • I loko o nā kaʻina hana kemika e pili ana i nā hopena o ka ua, hiki i ka CMC ke hana ma ke ʻano he mea pale ma ka hoʻomalu ʻana i ka nui a me ka nui o ka ua. Ma ka hoʻokaʻawale ʻana i nā ion metala a i ʻole ka hana ʻana i nā mea hoʻoheheʻe ʻia, kōkua ʻo CMC i ka pale ʻana i ka ua i makemake ʻole ʻia a hōʻoia i ka hoʻokumu ʻana o nā huahana i makemake ʻia me ka maʻemaʻe kiʻekiʻe a me ka hua.

ʻO ka sodium carboxymethyl cellulose (CMC) e hōʻike ana i nā waiwai paʻa i loko o kahi ākea o nā noi ʻoihana, me ka pale ʻana i ka unahi, ka pale ʻana i ka corrosion, ka hydrate inhibition, emulsion stabilization, flocculation inhibition, crystal growth inhibition, and precipitation inhibition. ʻO kāna versatility a me ka pono e lilo ia i mea hoʻohui waiwai no ka hoʻomaikaʻi ʻana i ke kaʻina hana, ka maikaʻi o ka huahana, a me ka hana i nā ʻoihana like ʻole.
