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

ʻO ka sodium carboxymethyl cellulose (CMC-Na no ka pōkole) he mea koʻikoʻi i ka wai-soluble polymer compound a hoʻohana nui ʻia i ka wai wili ʻaila. ʻO kāna mau waiwai kūʻokoʻa e lilo ia i mea pono ʻole i ka ʻōnaehana wai wili.

1. Nā waiwai kumu o ka sodium carboxymethyl cellulose

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

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

mea mānoanoa

Hoʻohana ʻia ʻo CMC-Na ma ke ʻano he mānoanoa i ka wai wili. ʻO kāna hana nui ka hoʻonui ʻana i ka viscosity o ka wai wili a hoʻonui i kona hiki ke lawe i nā ʻoki pōhaku a me nā ʻoki ʻoki. Hiki i ka viscosity kūpono o ka wai wili ke pale pono i ka hiolo ʻana o ka pā punawai a mālama i ka paʻa o ka luawai.

Mea ho'ēmi wai poho

I ka wā o ka wili ʻana, e komo ka wai wili i loko o nā pores o ka hoʻokumu ʻana, e hoʻolilo i ka wai i loko o ka wai wili, ʻaʻole wale ia e hoʻopau i ka wai wili, akā hiki ke kumu i ka hiolo ʻana o ka pā punawai a me ka pōʻino o ka waihona. Ma ke ʻano he mea hōʻemi hoʻoheheʻe wai, hiki i ka CMC-Na ke hana i kahi keke kānana paʻa ma ka paia o ka pūnāwai, e hōʻemi pono ana i ka nalowale o ka kānana ʻana o ka wai wili a me ka pale ʻana i ka hoʻokumu ʻana a me ka pā punawai.

Lubricant

I ka wā o ke kaʻina hana wili, ʻo ka friction ma waena o ka drill bit a me ka pā pūnāwai e hoʻohua nui i ka wela, e hopena i ka hoʻonui ʻia o ka mea hana drill. ʻO ka lubricity o CMC-Na kōkua i ka hoʻohaʻahaʻa ʻana i ka friction, hoʻemi i ka ʻaʻahu o ka mea hana drill, a hoʻomaikaʻi i ka pono wili.

Mea hoʻopaʻa

Hiki ke holo a hoʻohaʻahaʻa paha ka wai wili ma lalo o ka wela kiʻekiʻe a me ke kaomi kiʻekiʻe, no laila e nalowale ana kāna hana. Loaʻa i ka CMC-Na ke kūpaʻa wela maikaʻi a me ka paʻakai paʻakai, a hiki ke mālama i ka paʻa o ka wai wili ma lalo o nā kūlana paʻakikī a hoʻonui i kona ola lawelawe.

3. Mechanism o ka hana o ka sodium carboxymethyl cellulose

Hoʻoponopono viscosity

ʻO ka molecular structure o CMC-Na ka nui o nā hui carboxymethyl, hiki ke hana i nā paʻa hydrogen i loko o ka wai e hoʻonui i ka viscosity o ka hopena. Ma ka hoʻololi ʻana i ka paona molekala a me ka degere 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.

Ka mana kānana

Hiki i nā molekala CMC-Na ke hana i ʻekolu-dimensional network structure i loko o ka wai, hiki ke hana i kahi keke kānana paʻa ma ka paia o ka pūnāwai a hoʻemi i ka nalowale kānana o ka wai wili. ʻO ka hoʻokumu ʻana o ka keke kānana ʻaʻole i hilinaʻi wale ʻia ma ka neʻe ʻana o CMC-Na, akā ma luna o kona kaumaha molekala a me ke degere pani.

Lubrication

Hiki ke hoʻopili ʻia nā molekala CMC-Na ma ka ʻili o ka drill bit a me ka paia o ka luawai i loko o ka wai e hana i kahi kiʻi lubricating a hoʻemi i ke koena friction. Eia hou, hiki i ka CMC-Na ke ho'ēmi i ka hakakā ma waena o ka drill bit a me ka pā luawai ma ka hoʻoponopono ʻana i ka viscosity o ka wai wili.

Paʻa wela

Hiki iā CMC-Na ke mālama i ka paʻa o kona ʻano molekala ma lalo o nā kūlana wela kiʻekiʻe a ʻaʻole hiki ke hoʻohaʻahaʻa i ka wela. ʻO kēia no ka mea hiki i nā pūʻulu carboxyl i loko o kāna mau molekole ke hoʻokumu i nā paʻa hydrogen paʻa me nā molekole wai e pale aku i ka pōʻino wela kiʻekiʻe. Eia kekahi, ʻoi aku ka maikaʻi o ka paʻakai paʻakai ʻo CMC-Na a hiki ke mālama i kāna hana ma nā ʻano paʻakai. 

4. Hoʻohana Laʻana o Sodium Carboxymethyl Cellulose

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

ʻO ka hoʻohana ʻana o ka sodium carboxymethyl cellulose i loko o ka wai hoʻoheheʻe ʻana he ʻehā mau ʻano: ka mānoanoa, ka hōʻemi ʻana i ka wai, ka lubrication a me ka stabilization. ʻO kāna mau waiwai kino a me nā mea kemika e lilo ia i mea pono i ka ʻōnaehana wai wili. Me ka hoʻomau mau ʻana o ka ʻenehana drilling, e ʻoi aku ka laulā o ka noi no ka sodium carboxymethyl cellulose. Ma ka noiʻi e hiki mai ana, hiki ke hoʻopaʻa ʻia ke ʻano molecular a me nā ʻano hoʻololi o CMC-Na e hoʻomaikaʻi hou i kāna hana a hoʻokō i nā pono o nā kaiapuni wili paʻakikī.
