Pehea ka Polydadmac (poly diallyldimethylammonium chloride)

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 mālama 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 aʻe.

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 ʻana 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 e 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 ʻino 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 maka, 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 fila pulp saturated ma mua o ka loaʻa ʻana o nā hoʻopiʻi maikaʻi ʻole.

Ka hopena:

ʻO 1.Polydadmac me nā paona molekala like ʻole he kānana maikaʻi a me nā hopena paʻa i ka pulp ʻohe;
2. ʻOi aku ka maikaʻi o kāna kānana ʻana a me ka hoʻopaʻa ʻana i nā hopena i loaʻa i ka wā i emi ai ka nui o ka polydadmac i hoʻohana ʻia ma mua o ka hoʻopiʻi maikaʻi ʻole ma ka ʻili o nā fiber pulp saturated;

3.Low molecular weight polydadmac hasgood retention effect.High molecular weight he hopena kānana maikaʻi.Eia nō naʻe, ʻaʻohe ʻokoʻa koʻikoʻi o kona pono i ke kōkua ʻana i ka kānana a me ka mālama ʻana.
