Ke Keʻena nei i ka PolyDADMAC

Ke Keʻimi nei i ka Pilina ma waena o ke Kaumaha Molecular, Viscosity, Solid Content, a me ka Maikaʻi o PolyDADMAC

ʻO PolyDADMAC (ʻike ʻia hoʻi ʻo "polydiallyl dimethyl ammonium chloride") he polymer cationic i hoʻohana ʻia i nā kaʻina hana mālama wai. He waiwai nui ia no kona flocculation maikaʻi a me nā hopena coagulant. Ma ke ʻano he mea hoʻolako a me ka mea hāʻawi o nā kemika mālama wai, he mea nui e hoʻomaopopo i ka pilina ma waena o ke kaumaha molekala, ka viscosity a me ka ʻike paʻa o PolyDADMAC a me ka maikaʻi o ka huahana. Ma kēia ʻatikala, e ʻimi mākou i ka pilina ma waena o kēia mau ʻōkuhi a pehea e koho ai i nā huahana kiʻekiʻe e kūpono iā ʻoe.

ʻO ke kaumaha molekala, ka mānoanoa a me ka ʻike paʻa o PolyDADMAC nā ʻano koʻikoʻi e hoʻopilikia i kona hopena. Pili lākou i kekahi i kekahi. Eia ka wehewehe kikoʻī o lākou a me ka wehewehe kikoʻī o ko lākou pilina:

1. Pilina

ʻO ke kaumaha molekala e pili ana i ka lōʻihi awelika o ke kaulahao polymer PolyDADMAC.

ʻO ke kaumaha molekala kiʻekiʻe ke ʻano maʻamau o nā kaulahao polymer lōʻihi, hiki ke hoʻomaikaʻi i nā hiki flocculation o PolyDADMAC. A ʻo ke kaumaha molekala kiʻekiʻe e hāʻawi pinepine i kekahi mau hopena bridging, e ʻae ana i nā ʻāpana liʻiliʻi i loko o ka wai e hoʻopili ʻia. Hiki iā ia ke hoʻomaikaʻi i nā hopena mālama wai.

Eia nō naʻe, hiki i ke kaumaha molekala kiʻekiʻe loa ke alakaʻi i ka viscosity nui, kahi e hoʻopilikia ai i ka hana.

ʻO ke kaumaha molekala kahi hōʻailona koʻikoʻi o ka maikaʻi PDADMAC no ka mea e pili pololei ana ia i kāna hopena noi.

ʻO ka maʻamau, ʻo ke kaumaha molekala PDADMAC mai 50,000 a 700,000Da, a ʻo nā huahana me ke kaumaha molekala kiʻekiʻe loa e pono e piʻi i ka 3,000,000Da.

2. Ka mānoanoa

ʻO ka viscosity e pili ana i ke kū'ē ʻana o kahi hopena PolyDADMAC i ke kahe.

ʻO ka maʻamau, ʻo ka viscosity he 80-12,000mPa.s, a aia pū kekahi PolyDADMAC viscosity kiʻekiʻe me ka viscosity ʻoi aku ma mua o 100,000. Pili loa ka viscosity i ke kaumaha molekala, a ʻo nā kaumaha molekala kiʻekiʻe e hopena i ka viscosity kiʻekiʻe. A pili ka viscosity i ka solubility a me ka dispersibility o PDADMAC, a me kāna hana hana i nā noi. Inā kiʻekiʻe loa ka viscosity, e hoʻoulu ka viscosity kiʻekiʻe i kekahi mau pilikia hana (hoʻoili a hoʻoheheʻe, a pēlā aku). ʻO ka viscosity kahi mea nui no ke ana ʻana i ka maikaʻi o PDADMAC no ka mea e hōʻike ana i kona kaumaha molekala a me ka hana noi., ʻoiai ʻo ka PolyDADMAC haʻahaʻa he fluidity maikaʻi a maʻalahi hoʻi e pamu.

3. ʻIke paʻa

ʻO ka ʻike paʻa e pili ana i ka pakeneka kaumaha o ka polymer i loko o ka hopena PolyDADMAC.

ʻO ke kiʻekiʻe o ka ʻike paʻa, ʻo ia hoʻi ka hoʻemi ʻana i ke kumukūʻai mālama a me ka ukana. Eia nō naʻe, inā hoʻomākaukau ʻia kahi huahana me ke kaumaha molekala kiʻekiʻe loa ma ke ʻano he hopena 40%, ʻaʻole hiki ke ninini ʻia mai loko mai o ka pahu.

ʻO ka ʻike paʻa o PolyDADMAC he 10% a i ʻole 50%, ʻo ia hoʻi, ka hapa o nā mea kūpono maoli i loko o ka hopena.

ʻO ka maʻamau, ʻo ka ʻike paʻa o PolyDADMAC a mākou e kūʻai aku nei ma kahi o 40%. Loaʻa iā mākou nā kikoʻī ʻike paʻa ʻē aʻe.

Hiki iā ʻoe ke nānā i kaka wehewehe kikoʻī huahana o PolyDADMACno nā kikoʻī kikoʻī a me nā ʻōkuhi kikoʻī o PolyDADMAC.

ʻO ka pilina ma waena o lākou:

Ke kaumaha a me ka mānoanoa o ka molekala:

No ka ʻike paʻa like, ʻo ke kiʻekiʻe o ke kaumaha molekala, ʻo ka nui aʻe o ka viscosity.

ʻOi aku ka nui o ke kaumaha molekala, ʻoi aku ka kiʻekiʻe o ka viscosity.

Ka nui o ka paʻa a me ka mānoanoa:

No ke kaumaha molekala like, ʻo ke kiʻekiʻe o ka nui o ka mea paʻa, ʻo ka nui aʻe o ka viscosity.

ʻO ke kaumaha molekala, ka nui o ka paʻa, a me ka hana:

Ma kahi ʻike paʻa, ʻo ke kiʻekiʻe o ke kaumaha molekala, ʻoi aku ka maikaʻi o ka hopena, akā e piʻi aʻe ka viscosity.

Pehea e koho ai i ka PolyDADMAC e kūpono iā ʻoe

ʻO ka mānoanoa kūpono: e hōʻoia i ka wai, ka maʻalahi o ka solubility, a me ka hana flocculation maikaʻi.

Inā pono ʻoe e ʻimi i kahi mea hoʻolako hou e kūʻai iā PolyDADMAC, a laila pono mua ʻoe e hoʻoholo i ka ʻano o ka wai i hiki i kāu mea hoʻolako ke kōkua iā ʻoe e koho i kahi kumu hoʻohālike maikaʻi aʻe. A i ʻole hiki iā ʻoe ke haʻi i ka mea hoʻolako i ka hōʻailona a me ke kumu hoʻohālike o PolyDADMAC āu i hoʻohana ai ma mua. A i ʻole hiki iā ʻoe ke hoʻouna i kāu PolyDADMAC i kāu mea hoʻolako hou a e ʻae iā lākou e kōkua iā ʻoe e kālailai a koho. He mea nui loa ka hoʻāʻo ʻana i ka laʻana o ka PolyDADMAC hou, a pono ʻoe e hana pono i ka hoʻāʻo e hoʻoholo ai inā kūpono ke kumu hoʻohālike iā ʻoe.

Ma ke ʻano he loeaMea hoʻolako PolyDADMAC, hiki iā mākou ke hāʻawi iā ʻoe i nā lawelawe koho a hoʻouna iā ʻoe i nā laʻana manuahi. Inā he mau pono kāu, e ʻoluʻolu e kelepona mai iā mākou. E hoʻohālikelike mākou iā ʻoe me ka luna hoʻokele kūʻai ʻoihana loa e lawelawe iā ʻoe.
