18 Makahiki Hale Hana Carboxymethyl Cellulose Cmc-Battery Grade - Polyanionic cellulose (PAC) – Yeyuan

ʻO ka polyanionic cellulose (PAC) he wai-soluble cellulose ether derivative i hoʻomākaukau ʻia e ka hoʻololi kemika o ka cellulose maoli. He mea koʻikoʻi ia e hoʻoheheʻe ʻia i ka wai cellulose ether. Hoʻohana mau ʻia ʻo ia e like me kona paʻakai sodium a hoʻohana nui ʻia i ka ʻeli ʻaila, ʻoi aku ka nui o nā lua wai paʻakai a me ka ʻeli ʻaila ma waho.

PAC-noi ma ka aila

1. ʻO nā hana a PAC a me CMC ma ka māla aila penei:
- ʻO ka lepo i loaʻa iā PAC a me CMC hiki ke hana i ka pā punawai e hoʻohua i ka palaoa kānana lahilahi a paʻakikī me ka haʻahaʻa haʻahaʻa a hoʻemi i ka poho wai;
- Ma hope o ka hoʻohui ʻana i ka PAC a me ka CMC i loko o ka lepo, hiki i ka rig wili ke loaʻa ka ikaika ʻāʻā haʻahaʻa haʻahaʻa, e maʻalahi i ka lepo e hoʻokuʻu i ke kinoea i ʻōwili ʻia i loko, a hoʻolei koke i nā ʻōpala i loko o ka lua lepo;
- E like me nā dispersion ʻē aʻe i hoʻokuʻu ʻia, loaʻa i ka lepo wili i kekahi manawa ola, hiki ke hoʻopaʻa ʻia a hoʻonui ʻia ma ka hoʻohui ʻana i ka PAC a me CMC.
2. Loaʻa iā PAC a me CMC ka hana maikaʻi loa ma ka noi ʻaila:
- Kiʻekiʻe kiʻekiʻe o ka hoʻololi ʻana, maikaʻi like ʻole o ka hoʻololi ʻana, kiʻekiʻe viscosity a me ka haʻahaʻa haʻahaʻa, hoʻomaikaʻi maikaʻi i ka lawelawe ʻana i ka lepo;
- Ke kūpaʻa maikaʻi o ka wai, ka paʻakai paʻakai a me ke kūpaʻa alkali, kūpono no ka wai hou, ka wai kai a me ka ʻōpala wai i hoʻopaʻa ʻia i ka brine;
- He ʻano maikaʻi a kūpaʻa ka keke lepo i hoʻokumu ʻia, hiki ke hoʻopaʻa pono i ke ʻano o ka lepo palupalu a pale i ka hiolo ʻana o ka pā kumu;
- He kūpono ia no nā ʻōnaehana lepo me ka mana paʻa paʻa paʻakikī a me ka laulā ākea.
3. Nā hiʻohiʻona noi o PAC a me CMC i ka ʻaila ʻaila:
- Loaʻa iā ia ka hiki ke hoʻomalu i ka wai, ʻoi aku ka maikaʻi o ka hoʻemi ʻana i ka wai. Me ka haʻahaʻa haʻahaʻa, hiki iā ia ke hoʻomalu i ka nalowale o ka wai ma kahi kiʻekiʻe me ka ʻole o ka pili ʻana i nā waiwai ʻē aʻe o ka lepo;
- Loaʻa iā ia ka pale wela maikaʻi a me ke kūpaʻa paʻakai maikaʻi loa. Hiki iā ia ke loaʻa ka hiki ke hoʻemi maikaʻi i ka wai a me kekahi rheology ma lalo o kahi paʻakai paʻakai. ʻAʻole loli ka viscosity ma hope o ka hoʻoheheʻe ʻana i ka wai paʻakai. He kūpono loa ia no ka ʻeli ʻana i waho a me nā luawai hohonu;
- Hiki iā ia ke hoʻomalu maikaʻi i ka rheology o ka lepo a he thixotropy maikaʻi. He kūpono ia no kēlā me kēia lepo i hoʻokumu ʻia i ka wai i loko o ka wai hou, ka wai kai a me ka brine saturated;
- Eia hou, hoʻohanaʻia ka PAC e like me ka wai cementing e pale i ka wai mai ke komoʻana i nā pores a me nā haʻihaʻi;
- ʻO ka wai paʻi kānana i hoʻomākaukau ʻia me PAC he kūpaʻa maikaʻi i ka 2% KCl solution (pono e hoʻohui ʻia i ka wā e hoʻomākaukau ai i ka wai kānana kānana), hiki ke hoʻoheheʻe maikaʻi ʻia, hoʻohana maʻalahi, hiki ke hoʻomākaukau ʻia ma ka pūnaewele, wikiwiki ka hana ʻana o ka gel a me ke one ikaika. Ke hoʻohana ʻia i ka hana haʻahaʻa haʻahaʻa, ʻoi aku ka maikaʻi o kāna hopena kaomi kānana.
