Pehea ka hopena o Polydadmac (poly diallyldimethylammonium chloride) i kāna kānana a paʻa ʻana ma ka pepa (reed) pulp

No ke aha e koho ai iā Polydadmac?
E like me Kina ka papermaking ua lōʻihi i hoomaluia e ka graminaceous mea kanu puluniu maka mea, a me ka herbaceous mea kanu puluniu mea pōkole, me ka kiʻekiʻe maʻiʻo o heterocytes, mauʻu pulp i haʻahaʻa paʻa a me ka ilihune wai filtration ma ka pepa hana.
Hiki i ka Polydadmac ke hoʻomaikaʻi i ka pilikia o ka paʻa haʻahaʻa a me ka kānana wai maikaʻi ʻole i ke kaʻina hana pepa, hoʻomaikaʻi i ka huahana a me ka hoʻohana ʻana i nā mea maka, e hoʻemi i ke kumukūʻai o nā pepa a me ka pollution kaiapuni. Hiki i ka Polydadmac ke hoʻomaikaʻi i ka hana kānana wai o ka pulp a me ka hoʻokumu ʻana i ka pepa pepa.

Ke noiʻi nei kēia ʻatikala i nā hiʻohiʻona adsorption, hoʻopaʻa ʻana, a me ka kānana ʻana o Polydadmac me nā paona molekala like ʻole ma ke ʻano he mea hoʻohui i ka pulp reed bleached, a loaʻa ka hopena hope.

1.Adsorption o Polydadmac ma Reed Pulp
ʻO ka liʻiliʻi liʻiliʻi o ke kaumaha o ka Polydadmac, ʻoi aku ka nui o ka emi ʻana o ka adsorption rate me ka hoʻonui ʻana i ka nui o nā mea kōkua, ʻo ia paha ma muli o ka liʻiliʻi o ke kaumaha o ka Polydadmac, ʻoi aku ka nui o ka hiki ke hopu i nā anion. Pono ka polydadmac liʻiliʻi no ka nui o ka anion i loko o kahi ʻōnaehana saturated.

2. Ka hopena kānana o Polydadmac
Me ka piʻi ʻana o ka nui o ka polydadmac, ʻoi aku ka emi o ka filtration degere a laila hoʻonui, a kokoke a ʻoi aku paha ke kiʻekiʻe o ka filtration i ka blank ke piʻi ka nui o nā mea hoʻohui a ʻoi aku ma mua o 0.8%. ʻO ke ʻano o ka nui o ka Polydadmac ʻaʻole hiki ke kōkua i ka kānana, akā hoʻomāhuahua i ka kānana wai o ka pulp. ʻO ia hoʻi, ʻoi aku ka maikaʻi o ka kānana ʻana o Polydadmac ma mua o ka hoʻopiha ʻana i ka hoʻopiʻi maikaʻi ʻole ma ka ʻili o ka pulupulu.

3. Ka hopena paʻa o Polydadmac
Ke piʻi aʻe nei ke ʻano o ka Polydadmac, hoʻemi mua ka wai keʻokeʻo o ka pulp reed, a laila hoʻonui hou. Hōʻike kēia noiʻi ʻana i ka hoʻohui ʻana i ka polydadmac i ka pulp reed hiki ke hoʻomaikaʻi nui i ka paʻa ʻana o nā fiber pōkole a me nā ʻāpana maikaʻi a me ka hoʻohana ʻana i nā mea waiwai, a e hōʻemi i nā ukana wai. Ua ʻike ʻia ʻaʻole i hoʻopili ʻia ke ʻano kūpono o polydadmac e ko lākou kaumaha mole; ʻOi aku ka liʻiliʻi o ke kaumaha molekala o ka polydadmac, ʻoi aku ka maikaʻi o ka hopena paʻa. Akā ʻaʻole ʻike ʻia ka ʻokoʻa, a ʻoi aku ka maikaʻi o ka mālama ʻana o ka polydadmac paona molekala ʻē aʻe ma ka ʻili o nā pulu pulp saturated ma mua o ka loaʻa ʻana o nā hoʻopiʻi maikaʻi ʻole.
