ʻO ka hana hoʻokalakupua o ka Polyacrylamide ma ke kahua hana pepa

Polyacrylamidehe huaʻōlelo maʻamau no nā homopolymers o acrylamide a i ʻole copolymers me nā monomers ʻē aʻe. ʻO ia kekahi o nā polymers hiki ke hoʻohana nui ʻia i ka wai. Aia ka polyacrylamide ma ke ʻano o nā granules keʻokeʻo a hiki ke hoʻokaʻawale ʻia i ʻehā ʻano: non-ionic, anionic, cationic, a me amphoteric ionic.

Nā noi o ka Polyacrylamide ma ke kahua hana pepa

ʻO ke kaʻina hana pepa he mau pae, me ka pulping, screening, hoʻomaʻemaʻe, hoʻomaʻemaʻe, a me ka hana ʻana. I loko o kēia mau kaʻina hana, hana ʻia nā mea haumia like ʻole e like me nā fibers, fillers, a me nā uku. Inā ʻaʻole i wehe pono ʻia kēia mau mea haumia mai ka pulp, hiki iā lākou ke alakaʻi i nā pilikia e like me ka wai maikaʻi ʻole a me ka ikaika pepa haʻahaʻa. Hoʻohana nui ʻia ʻo Polyacrylamide e like me ka dispersant, ke kōkua paʻa, ke kōkua wai, flocculant, a me ka mea hoʻohana nui i ka hana pepa.

Ⅰ. Hoʻopuehu

ʻO ka hoʻohui ʻana i kahi polyacrylamide dispersant i ka wā o ka hana pepa hiki ke pale pono i ka agglomeration o nā fibers a hoʻomaikaʻi i ka lokahi o ka pepa. Hiki i ka huina haʻahaʻa ke hāpai i ka hoʻopuehu maikaʻi ʻana o nā fibermaking fibers a loaʻa i kahi hopena maikaʻi loa i ka hana pepa. Hiki iā ia ke hoʻomaikaʻi i ka like o ka pulp a me ka palupalu o ka pepa, a hoʻonui i ka ikaika o ka pepa. He kūpono ia no nā huahana pepa like ʻole e like me ka pepa toilet, napkins, nā ʻili maka, a me nā pepa lahilahi ʻē aʻe. Ma kekahi mau hale wili pepa, hiki iā ia ke pani piha i ka Polyethylene Oxide (PEO).

Ⅱ. Kōkua Paʻa

Hoʻohana maʻamau ʻia ʻo PAM ma ke ʻano he kōkua paʻa i ka ʻoihana hana pepa e hoʻonui i ka nui o ka paʻa ʻana o ka fiber a hōʻemi i ka hoʻokuʻu ʻana. ʻO kāna kumu hana ka hana ʻana i nā flocs nui me nā mea liʻiliʻi liʻiliʻi, hiki ke wehe maʻalahi ʻia mai ka pulp ma o ka kānana a i ʻole sedimentation.

Ⅲ. Kokua hookahe

Hiki nō hoʻi iā PAM ke lawelawe ma ke ʻano he kōkua wai i ka hana pepa. Hoʻonui ia i ka nui o ka hoʻoheheʻe ʻana, e hiki ai i ka hoʻoheheʻe ʻana i ka pepa ma ka mīkini pepa. Kōkua kēia i ka hoʻonui ʻana i ka wikiwiki o ka hana a hoʻemi i ka hoʻohana ʻana i ka ikehu ma ka hoʻopōkole ʻana i ka manawa maloʻo e pono ai no ka pepa.

Ⅳ. Agena Sizing

I kekahi mau hihia, hoʻohana ʻia ka polyacrylamide ma ke ʻano he mea nui i ka hana pepa e kāohi ai i ke komo ʻana o ka wai a me nā wai ʻē aʻe i loko o ka pepa pepa. Kōkua kēia i ka loaʻa ʻana o nā waiwai i makemake ʻia e like me ke kūpaʻa wai a me ka paʻa ʻana o ka ʻīnika, ʻoi loa i nā noi kahi e pono ai ka pepa e kū i ka makū a i ʻole ka paʻi ʻana.

Ⅴ. Flocculant

I ka wā o ke kaʻina hana hoʻomaʻemaʻe wai ma nā wili pepa, hiki ke hoʻohana ʻia ka polyacrylamide ma ke ʻano he flocculant e hoʻoneʻe i nā mea paʻa a me nā mea haumia i loko o ka wai ʻōpala. Kōkua ia i ka hana ʻana i nā ʻāpana nui i kapa ʻia ʻo flocs, a laila hiki ke wehe maʻalahi ma o ke kaʻina sedimentation a kānana. Hāʻawi kēia i ka hōʻemi ʻana i ka pollution wai a me ka hoʻomaikaʻi ʻana i ka hoʻomau ʻana o ke kaiapuni o ka ʻoihana hana pepa.

ʻO ka holoʻokoʻa, ʻo nā waiwai nui o ka polyacrylamide e lilo ia i mea hoʻohui nui i ka ʻoihana hana pepa, e hāʻawi ana i ka hoʻomaikaʻi maikaʻi ʻana, ka maikaʻi o ka huahana, a me ka hana o nā huahana pepa. ʻO ka hoʻohana ʻana i ka polyacrylamide ma ke kahua hana pepa e pili ana i ke kaulahao ʻoihana hana pepa holoʻokoʻa, mai ka hana pepa a hiki i ka mālama ʻana i ka wai. ʻAʻole ia e hoʻomaikaʻi wale i ka maikaʻi a me ka hana pono o ka pepa, e hōʻemi ana i nā kumukūʻai hana, akā hāʻawi pū kekahi i ka hāʻawi maikaʻi i ka mālama ʻana i ke kaiapuni.
