Ke ʻimi nei i ka PolyDADMAC

Ke ʻimi nei i ka pilina ma waena o ke kaumaha Molecular, Viscosity, Solid Content, a me ka maikaʻi o PolyDADMAC

ʻO PolyDADMAC (ʻike ʻia ʻo "polydiallyl dimethyl ammonium chloride") he polymer cationic i hoʻohana ʻia i nā kaʻina hana wai. Manaʻo ʻia no kona flocculation maikaʻi a me nā hopena coagulant. Ma ke ʻano he mea hoʻolako a me ka mea hāʻawi i nā kemika mālama wai, he mea koʻikoʻi ia e hoʻomaopopo i ka pilina ma waena o ke kaumaha molekala, 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 hōʻailona a pehea e koho ai i nā huahana kiʻekiʻe i kūpono iā ʻoe.

ʻO ke kaumaha molekala, viscosity a me ka ʻike paʻa o PolyDADMAC nā ʻāpana koʻikoʻi e pili ana i kona hopena. Pili like lākou. Eia ka wehewehe kikoʻī iā 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 polimer PolyDADMAC.

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

Eia nō naʻe, hiki i ke kaumaha molekala ke alakaʻi i ka viscosity kiʻekiʻe, e pili ana i ka hana.

He hōʻailona koʻikoʻi ka paona molekula o ka maikaʻi PDADMAC no ka mea pili pono i kāna hopena noi.

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

2. ʻO ka ʻili

ʻO ka Viscosity e pili ana i ke kū'ēʻana o kahi hopena PolyDADMAC e kahe.

ʻO ka maʻamau ka viscosity 80-12,000mPa.s, a aia pū kekahi PolyDADMAC kiʻekiʻe me ka viscosity ʻoi aku ma mua o 100,000. Pili loa ka viscosity i ke kaumaha mole, a ʻo ke kaupaona ʻana o nā molekala kiʻekiʻe ka 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, hiki i ka viscosity kiʻekiʻe ke kumu i kekahi mau pilikia hana (ka hoʻololi ʻana a me ka diluting, etc.) ʻO ka viscosity kahi ʻāpana koʻikoʻi no ke ana ʻana i ka maikaʻi o PDADMAC no ka mea e hōʻike ana i kona kaumaha molekala a me ka hana noi.

3. Maʻiʻo paʻa

ʻO ka maʻiʻo paʻa e pili ana i ka pākēneka kaumaha o ka polymer i ka hopena PolyDADMAC.

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

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

Hiki iā ʻoe ke nānā i kawehewehe kikoʻī huahana o PolyDADMACno nā kiko'ī kiko'ī a me nā hōʻailona kiko'ī o PolyDADMAC.

ʻO ka pilina ma waena o lākou:

Molekala kaumaha a me ka viscosity:

No ka maʻiʻo paʻa like, ʻoi aku ka kiʻekiʻe o ke kaumaha molekala, ʻoi aku ka nui o ka viscosity.

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

Maʻiʻo paʻa a me ka viscosity:

No ke kaumaha molekala like, ʻoi aku ka kiʻekiʻe o ka ʻike paʻa, ʻoi aku ka nui o ka viscosity.

Ke kaumaha molekala, maʻiʻo paʻa, a me ka hana:

Ma kahi maʻiʻo paʻa, ʻoi aku ka kiʻekiʻe o ke kaumaha molekala, ʻoi aku ka maikaʻi o ka hopena, akā e hoʻonui ka viscosity.

Pehea e koho ai i ka PolyDADMAC i kūpono iā ʻoe

ʻO ka viscosity kūpono: e hōʻoia i ka wai, hiki ke maʻalahi, a me ka hana flocculation maikaʻi.

Inā pono ʻoe e ʻimi i kahi mea hoʻolako hou e kūʻai aku i ka PolyDADMAC, a laila pono ʻoe e hoʻoholo i kāu ʻano wai maikaʻi 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 ʻano o PolyDADMAC āu i hoʻohana ai ma mua. A i ʻole hiki iā ʻoe ke hoʻouna i kāu PolyDADMAC i kēia manawa i kāu mea hoʻolako hou a ʻae iā lākou e kōkua iā ʻoe e nānā a koho. He mea koʻikoʻi loa ka hoʻāʻo ʻana o ka PolyDADMAC hou, a pono ʻoe e hana i ka hoʻāʻo me ka akahele e ʻike inā ʻoi aku ka kūpono o ke kumu hoʻohālike iā ʻoe.

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