Ka hoʻohana ʻana o ka sodium carboxymethyl cellulose i loko o ka wai wili

ʻO ka sodium carboxymethyl cellulose (CMC-Na no ka pōkole) kahi hui polymer koʻikoʻi e hoʻoheheʻe ʻia i ka wai a hoʻohana nui ʻia i loko o ka wai ʻeli aila. ʻO kona mau waiwai kū hoʻokahi e lilo ia i mea nui loa i ka ʻōnaehana wai ʻeli.

1. Nā waiwai kumu o ka sodium carboxymethyl cellulose

ʻO ka sodium carboxymethyl cellulose kahi cellulose ether anionic i hana ʻia e ka cellulose ma hope o ka mālama ʻana i ka alkali a me ka waikawa chloroacetic. Loaʻa i kona ʻano molekala kahi nui o nā hui carboxymethyl, ka mea e loaʻa ai ka solubility wai maikaʻi a me ke kūpaʻa. Hiki i ka CMC-Na ke hana i kahi hopena viscosity kiʻekiʻe i ka wai, me nā waiwai mānoanoa, paʻa a me ke ʻano hana kiʻiʻoniʻoni.

2. Ka hoʻohana ʻana o ka sodium carboxymethyl cellulose i loko o ka wai wili

Mea hoʻomānoanoa

Hoʻohana ʻia ʻo CMC-Na ma ke ʻano he mea hoʻomānoanoa i loko o ka wai wili. ʻO kāna hana nui, ʻo ia ka hoʻonui ʻana i ka mānoanoa o ka wai wili a hoʻoikaika i kona hiki ke lawe i nā ʻoki pōhaku a me nā ʻoki wili. Hiki i ka mānoanoa kūpono o ka wai wili ke pale pono i ka hiolo ʻana o ka paia o ka luawai a mālama i ke kūpaʻa o ka luawai.

Mea hoʻēmi i ka nalowale o ka wai

I ka wā o ke kaʻina hana ʻeli ʻana, e komo ka wai ʻeli i loko o nā lua o ke kahua, e lilo ai ka wai i loko o ke kahua ʻeli, ʻaʻole wale ia e hoʻonele i ka wai ʻeli, akā hiki nō hoʻi ke hana i ka hiolo ʻana o ka paia o ka luawai a me ka hōʻino ʻana i ka waihona wai. Ma ke ʻano he mea hōʻemi i ka nalowale o ka wai, hiki i ka CMC-Na ke hana i kahi keke kānana mānoanoa ma ka paia o ka luawai, e hōʻemi pono ana i ka nalowale o ka kānana o ka wai ʻeli a pale i ke kahua a me ka paia o ka luawai.

Mea hoʻoluʻu

I ka wā o ke kaʻina hana ʻeli ʻana, e hoʻoulu ka friction ma waena o ka ʻāpana wili a me ka paia o ka luawai i ka nui o ka wela, e hopena ana i ka hoʻonui ʻia ʻana o ka ʻaʻahu o ka mea hana wili. Kōkua ka lubricity o CMC-Na i ka hōʻemi ʻana i ka friction, hoʻemi i ka ʻaʻahu o ka mea hana wili, a hoʻomaikaʻi i ka pono o ka wili ʻana.

Mea hoʻopaʻa

Hiki i ka wai ʻeli ke flocculate a i ʻole e hōʻino ʻia ma lalo o ke ana wela a me ke kaomi kiʻekiʻe, a laila e nalowale ana kāna hana. Loaʻa iā CMC-Na ke kūpaʻa wela maikaʻi a me ke kūpaʻa paʻakai, a hiki ke mālama i ke kūpaʻa o ka wai ʻeli ma lalo o nā kūlana ʻino a hoʻolōʻihi i kona ola lawelawe.

3. Ke ʻano hana o ka sodium carboxymethyl cellulose

Hoʻoponopono ʻana i ka mānoanoa

Aia i loko o ke ʻano molekala o CMC-Na kahi nui o nā hui carboxymethyl, hiki ke hana i nā pilina hydrogen i loko o ka wai e hoʻonui i ka viscosity o ka hopena. Ma ka hoʻoponopono ʻana i ke kaumaha molekala a me ke kekelē pani o CMC-Na, hiki ke hoʻomalu ʻia ka viscosity o ka wai wili e hoʻokō i nā pono o nā kūlana wili like ʻole.

Kaohi kānana

Hiki i nā molekala CMC-Na ke hana i kahi ʻano pūnaewele ʻekolu-dimensional i loko o ka wai, hiki ke hana i kahi keke kānana mānoanoa ma ka paia o ka luawai a hōʻemi i ka nalowale o ka kānana o ka wai wili. ʻO ka hoʻokumu ʻia ʻana o ka keke kānana ʻaʻole ia e hilinaʻi wale ʻia ma ka nui o CMC-Na, akā, ma kona kaumaha molekala a me ke kekelē pani.

Ka lubrication

Hiki ke hoʻopili ʻia nā molekala CMC-Na ma luna o ka ʻili o ka ʻāpana wili a me ka paia o ka luawai i loko o ka wai e hana i kahi ʻili lubricating a hoʻemi i ke koina friction. Eia kekahi, hiki i ka CMC-Na ke hoʻemi pololei ʻole i ka friction ma waena o ka ʻāpana wili a me ka paia o ka luawai ma ka hoʻoponopono ʻana i ka viscosity o ka wai wili.

Paʻa wela

Hiki i ka CMC-Na ke mālama i ke kūpaʻa o kona ʻano molekala ma lalo o nā kūlana wela kiʻekiʻe a ʻaʻole hiki ke hoʻohaʻahaʻa ʻia i ka wela. ʻO kēia no ka mea hiki i nā hui carboxyl i loko o kāna mau molekala ke hana i nā pilina hydrogen paʻa me nā molekala wai e pale aku i ka hōʻino ʻia o ka mahana kiʻekiʻe. Eia kekahi, loaʻa iā CMC-Na ke kūpaʻa paʻakai maikaʻi a hiki ke mālama i kāna hana i nā ʻano saline. 

4. Nā Laʻana Hoʻohana o Sodium Carboxymethyl Cellulose

I ke kaʻina hana ʻeli maoli, he mea kupaianaha ka hopena o ka hoʻopili ʻana o ka sodium carboxymethyl cellulose. No ka laʻana, i loko o kahi papahana ʻeli hohonu, ua hoʻohana ʻia kahi ʻōnaehana wai ʻeli i loaʻa iā CMC-Na e kāohi pono i ke kūpaʻa a me ka nalowale o ka kānana o ka lua wai, hoʻonui i ka wikiwiki o ka ʻeli ʻana, a hoʻemi i ke kumukūʻai o ka ʻeli ʻana. Eia kekahi, hoʻohana nui ʻia ʻo CMC-Na i ka ʻeli ʻana i ke kai, a ʻo kona kūpaʻa paʻakai maikaʻi e hana maikaʻi ai i ke kaiapuni kai.

ʻO ka hoʻohana ʻana o ka sodium carboxymethyl cellulose i loko o ka wai wili e pili ana i ʻehā mau ʻano: ka mānoanoa, ka hōʻemi ʻana i ka nalowale o ka wai, ka lubrication a me ka hoʻopaʻa ʻana. ʻO kona mau waiwai kino a me ke kemika kū hoʻokahi e lilo ia i mea nui loa i ka ʻōnaehana wai wili. Me ka hoʻomohala mau ʻana o ka ʻenehana wili, e ʻoi aku ka laulā o nā manaʻolana noi o ka sodium carboxymethyl cellulose. I nā noiʻi e hiki mai ana, hiki ke hoʻomaikaʻi ʻia ke ʻano molekala a me nā ʻano hoʻololi o CMC-Na e hoʻomaikaʻi hou aku i kāna hana a hoʻokō i nā pono o nā wahi wili paʻakikī.
