Ka hoʻohana ʻana o CMC i ka ʻaila

Ke kumu hoʻohālike CMC papa ʻaila: PAC- HV PAC- LV PAC-L PAC-R PAC-RECMC- HVCMC- LV

1. ʻO nā hana a PAC a me CMC ma ka māla aila penei:

1. ʻO ka lepo i loaʻa iā PAC a me CMC hiki ke hana i ka pā punawai e hana i kahi keke kānana lahilahi a paʻa me ka haʻahaʻa haʻahaʻa, e hōʻemi ana i ka nalowale o ka wai;

2. Ma hope o ka hoʻohui ʻana i ka PAC a me ka CMC i ka lepo, hiki i ka rig rig ke loaʻa i kahi ikaika ʻoki mua haʻahaʻa, i maʻalahi ka lepo e hoʻokuʻu i ke kinoea i ʻōwili ʻia i loko, a i ka manawa like, hoʻolei koke ʻia ka ʻōpala i ka lepo. lua;

3. ʻO ka ʻeli ʻana i ka lepo, e like me nā hoʻokuʻu ʻana a me nā hoʻopuehu ʻē aʻe, loaʻa iā ia kahi ola paʻa. ʻO ka hoʻohui ʻana i ka PAC a me CMC hiki iā ia ke paʻa a hoʻolōʻihi i ke ola o ka papa.

2. Loaʻa iā PAC a me CMC nā waiwai maikaʻi loa ma nā noi ʻaila:

1. Kiʻekiʻe kiʻekiʻe o ka hoʻololi, maikaʻi like ʻole o ka hoʻololi ʻana, kiʻekiʻe viscosity, haʻahaʻa haʻahaʻa, hoʻomaikaʻi maikaʻi i ka pono o ka hoʻohana ʻana i ka lepo;

2. ʻO 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 lepo paʻakai wai paʻakai;

3. He maikaʻi a paʻa ka maikaʻi o ka pōkā lepo i hoʻokumu ʻia, hiki ke hoʻopaʻa pono i ke ʻano o ka lepo palupalu a pale i ka paia o ka luawai mai ka hiolo ʻana;

4. He kūpono ia no ka ʻōnaehana lepo nona ka mea paʻa paʻa paʻakikī e hoʻomalu a loaʻa i ka nui o nā loli.

3. Nā hiʻohiʻona noi o CMC a me PAC i ka ʻaila ʻaila:

1. Loaʻa iā ia ka mana kiʻekiʻe e hoʻomalu i ka nalowale o ka wai, ʻoi aku ka maikaʻi o ka hoʻohaʻahaʻa pohō kiʻekiʻe, hiki ke hoʻomalu i ka poho wai ma kahi kiʻekiʻe ma kahi haʻahaʻa haʻahaʻa me ka ʻole o ka pili ʻana i nā waiwai ʻē aʻe o ka lepo;

2. ʻO ke kūpaʻa wela maikaʻi a me ke kūpaʻa paʻakai maikaʻi loa. Ma lalo o kahi paʻakai paʻakai, hiki ke loaʻa ka mana maikaʻi e hōʻemi i ka nalowale o ka wai a me kekahi rheology. Ma hope o ka hoʻoheheʻe ʻia ʻana i ka wai paʻakai, ʻaneʻane loli ʻole ka viscosity, kūpono loa no nā noi waho. ʻO nā koi ʻana a me ka luawai hohonu;

3. Hiki iā ia ke hoʻomalu maikaʻi i ka rheology o ka lepo, he thixotropy maikaʻi, a he kūpono ia no kēlā me kēia lepo wai i loko o ka wai hou, ka wai kai, a me ka wai paʻakai paʻakai;

4. Eia kekahi, hoʻohanaʻia ka PAC e like me ka wai cementing, hiki ke pale i ka wai mai ke komoʻana i nā pores a me nā haʻihaʻi;

5. ʻO ka kānana i hoʻomākaukau ʻia me PAC hiki ke kū i ka 2% KCL solution (pono e hoʻohui ʻia i ka wā e hoʻonohonoho ai i ka filtrate) a loaʻa ka solubility maikaʻi, maʻalahi e hoʻohana, hiki ke hoʻomākaukau ʻia ma ka pūnaewele, a loaʻa ka wikiwiki gelation wikiwiki a me ka hiki ke lawe i ke one. Hoʻohana ʻia ia i ka hoʻokumu ʻana, a ʻoi aku ka maikaʻi o kāna hopena kānana kaomi.
