Te tirotiro i te PolyDADMAC

Te Tirotiro i te Hononga i waenga i te Taumaha Molecular, Viscosity, Ihirangi Toka, me te Kounga o PolyDADMAC

Ko te PolyDADMAC (e mohiotia ana ko "polydiallyl dimethyl ammonium chloride") he polymer cationic e whakamahia ana i roto i nga tukanga maimoatanga wai. Ka whakanuia mo te pai o te kapoipoi me nga paanga coagulant. Hei kaiwhakarato me te tohatoha o nga matū maimoatanga wai, he mea nui ki te mohio ki te hononga i waenga i te taumaha ngota, te pokey me te kiko totoka o PolyDADMAC me te kounga hua. I roto i tenei tuhinga, ka tirotirohia e matou te hononga i waenga i enei tohu me pehea te whiriwhiri i nga hua kounga teitei e tika ana mo koe.

Ko te taumaha ngota, te pokey me te kiko totoka o PolyDADMAC he tawhā matua e pa ana ki tona paanga. He hononga tahi raua. E whai ake nei he whakamaarama mo ratou me te whakamaarama mo o raatau hononga:

1. Whanaungatanga

Ko te taumaha ngota e tohu ana ki te roa toharite o te mekameka polymer PolyDADMAC.

Ko te nui ake o nga taumahatanga ngota ko te tikanga he roa ake nga mekameka polymer, ka taea te whakapai ake i te kaha o te kapo o PolyDADMAC. A ko nga taumahatanga rapoi teitei ake e whakarato ana i etahi paanga piripono, ka taea te hono tahi nga matūriki iti o te wai. Ka taea te whakapai ake i nga paanga maimoatanga wai.

Heoi, he nui rawa te taumaha o te ngota ngota ka nui ake te potata, ka pa ki te mahi.

Ko te taumaha ngota he tohu nui mo te kounga PDADMAC na te mea e pa ana ki tana paanga tono.

Ko nga taumahatanga ngota ngota PDADMAC te nuinga o te waa mai i te 50,000 ki te 700,000Da, a ko nga hua me te taumaha ngota tino teitei kia nui atu ki te 3,000,000Da.

2. Viscosity

Ko te Viscosity e tohu ana ki te parenga o te otinga PolyDADMAC kia rere.

I te nuinga o te waa ko te 80-12,000mPa.s te viscosity, kei reira ano hoki te PolyDADMAC teitei me te viscosity nui atu i te 100,000. He tata te hononga o te pokey ki te taumaha ngota, me te nui ake o nga taumahatanga ngota ka hua ake te viscosity. A ka pa te pokey ki te memehatanga me te whakamararatanga o PDADMAC, me ona mahi whakahaere i roto i nga tono. Mena he tiketike rawa te pokey, ko te pokey teitei ka raru etahi mahi (te whakawhiti me te whakaheke, me etahi atu) Ko te Viscosity he tawhā nui mo te ine i te kounga o te PDADMAC na te mea e whakaatu ana i tana taumaha ngota me te mahi tono., i te mea he pai te rere o te PolyDADMAC me te ngawari ki te pupuhi.

3. Ihirangi totoka

Ko te ihirangi totoka e pa ana ki te ōrau taumaha o te waerau i roto i te otinga PolyDADMAC.

Ko te nui o nga mea totoka ko te whakaiti i te utu rokiroki me nga uta. Heoi, ki te rite te hua ki te taumaha ngota tino teitei hei otinga 40%, e kore e taea te riringi ki waho o te pahū.

Ko te ihirangi totoka o PolyDADMAC he 10%, 50% ranei, ara, ko te wahanga o nga matū whai hua i roto i te otinga.

I te nuinga o te wa, ko te ihirangi totoka o PolyDADMAC e hokona ana e matou he 40%. Kei a matou ano etahi atu korero mo te ihirangi totoka.

Ka taea e koe te tirotiro i tewhakaahuatanga hua taipitopito o PolyDADMACmo nga korero motuhake me nga tohu taipitopito o PolyDADMAC.

Te hononga i waenganui i a raatau:

Te taumaha ngota me te viscosity:

Mo te ihirangi totoka ano, ka nui ake te taumaha ngota, ka nui ake te pokey.

Ko te nui ake o te taumaha ngota, ka teitei ake te pokey.

Ihirangi totoka me te pokey:

Mo te taumahatanga rapoi kotahi, ka nui ake te kiko totoka, ka nui ake te pokey.

Te taumaha ngota, te ihirangi totoka, me te mahi:

I tetahi ihirangi totoka, ko te teitei ake o te taumaha ngota, ka pai ake te paanga, engari ka piki ake te viscosity.

Me pehea te whiriwhiri i te PolyDADMAC e pai ana ki a koe

Te pokey whaitake: te whakarite i te rere, te ngawari o te whakarewatanga, me te pai o te mahi flocculation.

Mena ka hiahia koe ki te kimi i tetahi kaiwhakarato hou hei hoko i te PolyDADMAC, katahi koe me whakatau i to hanganga kounga wai kia taea ai e to kaiwhakarato te awhina i a koe ki te whiriwhiri i tetahi tauira pai ake. Ka taea ranei e koe te korero ki te kaiwhakarato te tohu me te tauira o PolyDADMAC i whakamahia e koe i mua. Ka taea ranei e koe te tuku i to PolyDADMAC o naianei ki to kaiwhakarato hou ka waiho ma ratou e awhina i a koe ki te tātari me te whiriwhiri. He mea nui te whakamatautau tauira o te PolyDADMAC hou, me ata mahi koe i te whakamatautau kia mohio ai he pai ake te tauira mo koe.
