Hoʻohālikelike o ka waiwai kū'ē i ka nalowale wai o ka cellulose Polyanionic i hana ʻia e ke kaʻina hana palaoa a me ke kaʻina hana slurry

ʻO ka Polyanionic cellulose (PAC) kahi polymer wai-hoʻoheheʻe ʻia i loaʻa mai ka cellulose a hoʻohana pinepine ʻia ma ke ʻano he mea hoʻohui kaohi wai i nā wai ʻeli i hoʻohana ʻia i ka ʻimi ʻaila a me ke kinoea. ʻO nā ʻano nui ʻelua o ka hana ʻana i ka PAC ʻo ia ke kaʻina hana palaoa a me ke kaʻina hana slurry. Eia kahi hoʻohālikelike o ka waiwai pale wai o ka PAC i hana ʻia e kēia mau kaʻina hana ʻelua:

1. Kaʻina Hana Palaoa:
   • ʻAno Hana: I ke kaʻina hana palaoa, hana ʻia ka PAC ma ka hoʻohui ʻana i ka cellulose me kahi alkali, e like me ka sodium hydroxide, e hana i kahi palaoa cellulose alkaline. A laila hoʻohui ʻia kēia palaoa me ka waikawa chloroacetic e hoʻokomo i nā hui carboxymethyl ma luna o ke kuamoʻo cellulose, e hopena ana i ka PAC.
   • Ka Nui o nā ʻĀpana: ʻO ka PAC i hana ʻia e ke kaʻina hana palaoa he ʻoi aku ka nui o ka nui o nā ʻāpana a loaʻa paha nā agglomerates a i ʻole nā ​​​​​​hui o nā ʻāpana PAC.
   • Ke Kū'ē ʻana i ka Pohō Wai: Hōʻike ka PAC i hana ʻia e ke kaʻina hana palaoa i ka maikaʻi o ke kū'ē ʻana i ka pohō wai i nā wai ʻeli. Eia nō naʻe, ʻo ka nui o nā ʻāpana a me ke alo o nā agglomerates e hopena i ka lohi o ka hydration a me ka hoʻopuehu ʻana i nā wai ʻeli wai, kahi e hiki ai ke hoʻopilikia i ka hana kaohi pohō wai, ʻoiai ma nā kūlana wela kiʻekiʻe a me ke kaomi kiʻekiʻe.
2. Kaʻina Hana Slurry:
   • ʻAno Hana: I ke kaʻina hana 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 chloroacetic acid e hana pololei i ka PAC i loko o ka hopena.
   • Ka Nui o nā ʻĀpana: ʻO ka PAC i hana ʻia e ke kaʻina hana slurry he ʻoi aku ka liʻiliʻi o ka nui o nā ʻāpana a ua hoʻopuehu like ʻia i loko o ka hopena i hoʻohālikelike ʻia me ka PAC i hana ʻia e ke kaʻina hana palaoa.
   • Ke Kū'ē ʻana i ka Pohō Wai: ʻO ka PAC i hana ʻia e ke kaʻina hana slurry e hōʻike pinepine ana i ke kū'ē maikaʻi loa i ka pohō wai i nā wai wili. ʻO ka liʻiliʻi o ka nui o nā ʻāpana a me ka hoʻopuehu like ʻana e hopena i ka hydration wikiwiki a me ka hoʻopuehu ʻana i nā wai wili wai, e alakaʻi ana i ka hana kaohi wai i hoʻomaikaʻi ʻia, ʻoiai i nā kūlana wili paʻakikī.

Hiki i ka PAC i hana ʻia e ke kaʻina hana palaoa a me ka PAC i hana ʻia e ke kaʻina hana slurry ke hāʻawi i ke kū'ē maikaʻi ʻana i ka nalowale o ka wai i nā wai wili. Eia nō naʻe, hiki i ka PAC i hana ʻia e ke kaʻina hana slurry ke hāʻawi i kekahi mau pono, e like me ka hydration wikiwiki a me ka hoʻopuehu ʻana, e alakaʻi ana i ka hoʻonui ʻana i ka hana kaohi nalowale o ka wai, ʻoi aku hoʻi i nā wahi wili wela kiʻekiʻe a me ke kaomi kiʻekiʻe. I ka hopena, ʻo ke koho ma waena o kēia mau ʻano hana ʻelua e hilinaʻi paha i nā koi hana kikoʻī, nā noʻonoʻo kumukūʻai, a me nā mea ʻē aʻe e pili ana i ka noi wai wili.
