Ko te Polyethyleneimine (whakarāpopototanga ko PEI) he wai kore tae, he kowhai rānei, he tino matotoru. Tau CAS9002-98-6. Ka wairewa ki te wai, te etanoru, he waikura, kāore e wairewa ki te benzene me te acetone. Ka puta te ua ina tūtaki te otinga polyethyleneimine ki te waikawa whanariki he iti iho i te 2.4 te pH. He pai te utu o te otinga wai, ā, mā te tāpiri o te formaldehyde ka puta he haukū. Ka whakamahia te Polyethyleneimine PEI hei matū kaha mākū mō te pepa manawa kore-rahi, ā, ka taea e te matū pupuri me te matū patu i roto i te tukanga hanga pepa te whakaiti i te nui o te patu o te penupenu. Whakapai ake i te kaha whakamaroke o te pepa. Ka piki ake te maroke o te pepa mā te 1% – 4%. Ka piki ake te kaha whakaputa mā te 5% – 20%.

1. Ka whakamahia te Polyethyleneimine PEI hei matū kaha mākū mō te pepa hau kore-rahi, hei matū pupuri me te matū patu i roto i te tukanga hanga pepa, ka taea e te PEI te whakaiti i te kaha patu o te penupenu. Whakapai ake i te kaha whakamaroke o te pepa. Ka piki ake te maroke o te pepa mā te 1% – 4%. Ka piki ake te kaha whakaputa mā te 5% – 20%.
2. He whānuitia te whakamahinga o te otinga polyethyleneimine i roto i ngā mara o te waituhi tā, te paninga, te piripiri me ētahi atu.
3. E whakamahia ana te PEI i roto i te maimoatanga wai mō te hanga pepa, te otinga whakakikorua hiko me te kaiwhakamarara.
4. Ko te polyethyleneimine e whakamahia ana hei matū kapia epoxy, hei mimiti aldehyde me te mea whakapiri tae.

1. Ngā Kaupapa Matua o te Taupānga

Te Whakapaipai i te Wai Mā i te Hanga Pepa: Ka whakakapi i ngā tote konumohe tuku iho, ka whakapai ake i te mārama o te wai, ka whakaiti hoki i te COD.

Te Whakakikorua i te Maimoatanga Wai Para: Ka hopu i te Cu²⁺, Ni²⁺, me te Cr⁶⁺ i te wā kotahi, kia tutuki ai ngā paerewa o te tukunga.

Wai Para Tae: Te tere tango tae >95%, ka whakaitihia ngā utu whakahaere mā te 30%.

2. He whānui te awhe taumaha ngota o te PEI, arā, 500–750,000, ā, ka taea te whaka-acetylate, te whaka-carboxylate, te whaka-PEGylated, me te whaka-fluorescently hei whakatutuki i te hoahoa wairewa-wai, wairewa-hinu, me te arotahi i runga i te tono.

3. He rite ki te BASF, Catalyst me ētahi atu waitohu. He rite tonu ngā utu, ā, he whakataetae ake.

4. Whakaratohia ngā mōhiotanga hangarau takitahi. Whakamaua ngā whakaritenga motuhake kia rite ki ngā tono hua a te kiritaki.

✅He nui ngā rōpū amino o te PEI, ā, he maha hoki ngā wāhi tauhohenga
