PolyDADMAC, he ingoa matū uaua, ngaro hoki, he wāhanga nui o tō tātou oranga o ia rā. Hei tohu mō ngā matū pūmua, e whakamahia whānuitia ana te PolyDADMAC i roto i ngā mara maha. Heoi, e mārama ana koe ki ōna āhuatanga matū, te āhua o te hua, me te paitini? Muri iho, ka hoatu e tēnei tuhinga he māramatanga hōhonu ki a koe mō te PolyDADMAC.
Ko ngā āhuatanga matū o te PolyDADMAC e whakatau ana i ōna āhuatanga ahurei. Hei polyelectrolyte cationic kaha, ka tukuna te PolyDADMAC hei wai matotoru kore tae ki te kōwhai mārama, he pērara mā rānei i ētahi wā. Nā ōna āhuatanga haumaru me te kore paitini ka whakamahia whānuitia i roto i ngā mara pēnei i te maimoatanga wai, te kakahu, te hanga pepa, me ngā mara hinu. Hei tāpiri, he ngāwari te wairewa o te PolyDADMAC ki te wai, kāore e mura, he kaha te piripono, he pai te pumau o te wai, kāore e pāngia e ngā huringa pH, ā, he āhuatanga pai rawa atu pēnei i te ātete ki te chlorine. He mea whakamahi noa hei flocculant, ā, i ētahi wā ka tāpirihia ki ngā algaecides. E ai ki te pūrongo he pānga tahi te PDMDAAC me te WSCP me te poly-2-hydroxypropyl dimethylammonium chloride.
He pēhea te whai huatanga o te PolyDADMAC?
He kaha te PolyDADMAC, ā, he rerekē ngā mahi a ia i roto i ngā mara rerekē. Ina koa, i roto i te mara o te maimoatanga wai, ka whakamahia te PolyDADMAC hei whakapūmau cationic me te whakakōkī. Mā te mimiti me te piriti, ka taea e ia te tango pai i ngā totoka me ngā poke i roto i te wai, me te whakapai ake i te kounga o te wai. I roto i te umanga kakahu, ka taea e te PolyDADMAC, hei kaihoko whakapiri tae kore-formaldehyde, te whakapai ake i te pānga whakapiri tae o ngā tae, me te hanga i ngā kakahu kia kanapa te tae, kia ātete hoki ki te memeha. I roto i te tukanga hanga pepa, ka whakamahia te PolyDADMAC hei kaihoko hopu para anionic me te whakatere whakaora AKD, e āwhina ana ki te whakapai ake i te kounga o te pepa me te whakaiti i ngā utu whakaputa. Hei tāpiri, i roto i te umanga mara hinu, ka whakamahia te PolyDADMAC hei kaiwhakaū uku mō te keri me te whakarerekē cationic pakaru waikawa i roto i te weronga wai hei whakapai ake i te whakaora mara hinu.
Heoi, ehara te PolyDADMAC i te mea tino pai. Ahakoa he maha ngā āhuatanga me ngā wāhi tono pai, me aro tonu koe ki ngā take haumaru i te wā e whakamahia ana. Hei tauira, me karo te pa tika ki te kiri me ngā kanohi i te wā e whakamahia ana hei ārai i te riri. Hei tāpiri atu ki tēnā, me hiri me te rongoa i muri i te whakamahinga kia kore ai e pa ki ngā waikura kaha, ā, me rongoa ki te wāhi hauhautanga, maroke hoki. Ahakoa kāore he paitini o te PolyDADMAC, me tūpato tonu te whakahaere me te whai i ngā ture haumaru me ngā tikanga whakahaere.
Hei whakarāpopototanga, he matū polymer te PolyDADMAC, e whakamahia whānuitia ana i roto i ngā mara maha. Nā ōna āhuatanga matū ahurei me te mahi tino pai, he mea pai mō te maimoatanga wai, te kakahu, te pepa, me ngā mara hinu. Heoi anō, me aro tonu koe ki ngā take haumaru i te wā e whakamahia ana, me te whai i ngā ture me ngā tikanga whakahaere e tika ana. Mā te whakarite kia haumaru, kia tika hoki te whakamahinga o te PolyDADMAC ka taea e tātou te tino whakatutuki i tōna pūmanawa, ā, ka nui ake te whai hua me ngā painga ki tō tātou oranga me te mahi.
