He pēhea te mahi a te polyamine?

Polyamine, he mea nuipolyelectrolyte kationika, he kaha te mahi a te polyamine i roto i ngā momo whakamahinga nā ōna āhuatanga ahurei me ōna tikanga. Me ruku tātou ki roto i ngā mahi a te polyamine me te tūhura i ōna whakamahinga maha.

Ngā Āhuatanga me ngā Whakamahinga o ngā Polyamines:

He homopolymer rārangi te Polyamine, ā, he tino pai te wairewatanga ki te wai me te hototahitanga, ā, he tino maha ngā whakamahinga puta noa i ngā ahumahi rerekē. Nā tōna āhua pumau, kāore e pāngia e ngā rerekētanga pH, ā, he ātete hoki ki te pirau o te chlorine, he mea pai rawa atu mō ngā momo tono maha. Hei tāpiri, he ātete te polyamine ki te pāmahana teitei me te pēhanga teitei, tae atu ki te ātete ki ngā āhuatanga kutikuti chlorine, tere teitei rānei, e whakarite ana i te mahi tino pai i roto i ngā taiao uaua.

Heoi anō, kāore te polyamine i te paitini, ahakoa ka pāngia pea te kiri me ngā kanohi, e whakanui ana i te hiranga o te whakahaere tika me ngā mahi whakatūpato haumaru i te wā e whakamahia ana.

Te Tikanga Mahi a ngā Polyamines:

Ina whakamahia hei whakapūkara, ka mahi te polyamine mā roto i tētahi tikanga e uru ana ki te whakakore hiko me te hononga mimiti. Ko te whai huatanga o te polyamine hei whakapūkara e pā ana ki te taumaha ngota o te polymer, te nui o te cationicity, me te nui o te peka. Ko te taumaha ngota teitei, te cationicity, me te peka ka hua ake he mahi pai ake. Hei tāpiri, ka whakaatuhia e te polyamine ngā kaha taunga, e kitea nuitia ana ina honoa ki te PAC (polyaluminum chloride), ka hua ake he pānga tahi me te pai ake o te mahi.

I roto i ngā mahi whaihua, he rite te whakamahinga me te horopeta o te polyamine ki ērā o te PA (polyacrylamide) me te PDADMAC (polydiallyldimethylammonium chloride). Heoi, he nui ake te kiato utu, he iti ake te taumaha ngota, he nui ake ngā monomer toenga, ā, he ahurei hoki ngā āhuatanga hanganga o te polyamine ki te whakatauritea ki te PA me te PDADMAC.

Te mahi tahi a te Polyamine me te PAC:

He tino whai hua te polyamine ki te tango i ngā mea rauropi me ngā tae mai i ngā wai e rere ana, e rere ana rānei i roto i te mira pepa. Ina whakamahia ngātahitia me te PAC, ka whakarei ake te polyamine i te tukanga whakapūmau, ka hua ake he tangohanga paru me te whakaiti i te horopeta PAC. E whakaatu ana tēnei mahi tahi i te mahi tahi i waenga i te polyamine me te PAC i roto i ngā tono maimoatanga wai.

Te Tākai me te Rokiroki:

Ko te tikanga, ka tākaihia te polyamine ki roto i ngā pūwero kirihou 210 kg, i ngā tāke IBC (Ipu Waenga Papatahi) 1100 kg rānei. Me penapena ki roto i te wāhi maroke, he pai te hauhautanga i te pāmahana rūma, kia roa ai te ora mō te 24 marama.

Hei whakamutunga, ka puta te polyamine hei otinga maha-āhuatanga me ngā tono kanorau i roto i te maimoatanga wai, te wehenga hinu-wai, me ngā tukanga whakahaere para. Nā ōna āhuatanga ahurei me te kaha mahi tahi me ētahi atu matū, he mea nui tēnei taputapu i roto i ngā momo taiao ahumahi, e whai wāhi ana ki te whakapai ake i te whai huatanga me te pumau o te taiao.

Ko tō mātou wheako ahurei, whānui hoki i roto i tete tuku me te whakamahi i te polyaminehe tino painga ki ā mātou kiritaki mō te tautoko me te tohungatanga ki te arotau i ngā tukanga me te ōhanga whakahaere. Mena kei te hiahia koe i tēnei hua, tēnā whakapā mai.
