Ka hoʻohālikelike o ka wai e kūʻē i ka waiwai o ka polyanionic cellulose i hana ʻia e ke kaʻina hana palaoa a me ke kaʻina slurry.

ʻO ka polyanionic cellulose (PAC) he polymer hiki ke hoʻoheheʻe ʻia i ka wai i loaʻa mai ka cellulose a hoʻohana mau ʻia ma ke ʻano he mea hoʻohui hoʻoheheʻe wai i nā wai wili i hoʻohana ʻia i ka ʻimi ʻaila a me ke kinoea.ʻO nā ala nui ʻelua o ka hana ʻana i ka PAC ʻo ke kaʻina palaoa a me ke kaʻina slurry.Eia ka hoʻohālikelike ʻana o ka waiwai kūʻē o ka wai o ka PAC i hana ʻia e kēia mau kaʻina hana ʻelua:

1. Kaʻina hana palaoa:
   • Ke Kaʻina Hana Hana: Ma ke kaʻina hana palaoa, hana ʻia ka PAC ma ka hana ʻana i ka cellulose me kahi alkali, e like me ka sodium hydroxide, e hana ai i ka palaoa cellulose alkaline.Hoʻopili ʻia kēia palaoa me ka waika chloroacetic e hoʻokomo i nā pūʻulu carboxymethyl ma luna o ka iwi kuamoʻo cellulose, ka hopena i ka PAC.
   • Nui ʻĀpana: ʻO ka PAC i hana ʻia ma ke kaʻina hana palaoa ʻoi aku ka nui o ka nui o nā ʻāpana a loaʻa paha nā agglomerates a i ʻole nā ​​​​hui o nā ʻāpana PAC.
   • ʻO ke kūʻē ʻana o ka wai: ʻo ka PAC i hana ʻia e ke kaʻina paila palaoa e hōʻike maʻamau i ke kūpaʻa maikaʻi o ka pohō wai i nā wai wili.Eia nō naʻe, ʻo ka nui o ka nui a me ka hiki ʻana mai o nā agglomerates hiki ke hopena i ka hydration lohi a me ka hoʻopuehu ʻana i nā wai wili e pili ana i ka wai, hiki ke hoʻopilikia i ka hana hoʻokele wai, ʻoi aku ka nui o nā kūlana kiʻekiʻe a me nā kūlana kiʻekiʻe.
2. Kaʻina Slurry:
   • Hana Hana: Ma ke kaʻina slurry, hoʻopuehu mua ʻia ka cellulose i loko o ka wai e hana i kahi slurry, a laila hoʻopili ʻia me ka sodium hydroxide a me ka waikawa chloroacetic e hana pololei i ka PAC i ka hopena.
   • Nui ʻāpana: ʻO ka PAC i hana ʻia e ke kaʻina slurry ʻoi aku ka liʻiliʻi o ka nui o ka ʻāpana a ʻoi aku ka like ʻole o ka hoʻopuehu ʻia i loko o ka hopena i hoʻohālikelike ʻia me ka PAC i hana ʻia e ke kaʻina palaoa.
   • Kū'ē Waiwai: ʻO ka PAC i hana ʻia e ke kaʻina hana slurry e hōʻike ana i ke kūpaʻa maikaʻi loa o ka hoʻoheheʻe ʻana i ka wai.ʻO ka liʻiliʻi liʻiliʻi a me ka hoʻopuehu like ʻana e hopena i ka hydration wikiwiki a me ka hoʻopuehu ʻana i nā wai hoʻoheheʻe wai, e alakaʻi ana i ka hoʻomaikaʻi ʻana i ka hana hoʻokele wai, ʻoi aku ka paʻakikī o nā kūlana wili.

ʻO nā PAC ʻelua i hana ʻia e ke kaʻina palaoa a me ka PAC i hana ʻia e ke kaʻina slurry hiki ke hāʻawi i ke kūpaʻa maikaʻi o ka pohō wai i nā wai wili.Eia nō naʻe, hiki i ka PAC i hana ʻia e ke kaʻina slurry ke hāʻawi i kekahi mau mea maikaʻi, e like me ka wikiwiki o ka hydration a me ka hoʻopuehu ʻana, e alakaʻi ana i ka hoʻomaikaʻi ʻana i ka hana hoʻoheheʻe ʻana i ka wai, ʻo ia hoʻi i nā kaiapuni wili kiʻekiʻe a me ke kaomi kiʻekiʻe.ʻO ka mea hope loa, ʻo ke koho ma waena o kēia mau ʻano hana ʻelua e hilinaʻi ʻia i nā koi hana kikoʻī, nā kumukūʻai noʻonoʻo, a me nā mea ʻē aʻe e pili ana i ka noi wai drilling.
