Ko te PolyDADMAC, ko tōna ingoa katoa ko te polydimethyldiallylammonium chloride, he pūhui wairewa-katoni e whakamahia whānuitia ana i roto i te mara o te maimoatanga wai. Nā tōna matotoru utu katonika ahurei me te wairewatanga teitei ki te wai, he matū whakapūmau whai hua te PolyDADMAC ka taea te tango i te paru, te tae me ētahi atu poke i roto i te wai. Heoi, i roto i ngā tono mahi, he maha te whakamahinga heimea whakapūkarahei whakamahi tahi me ētahi atu matū whakakōkī hei rongoā i te paru ahumahi.
Ngā āhuatanga me te tikanga mahi a PolyDADMAC
Ka tere te mimiti me te whakakotahi a PolyDADMAC i ngā matūriki colloidal kua utua kinotia me ngā totoka iri i roto i te wai nā te mea he nui te kiato o te utu cationic. Ko te tikanga mahi a te PolyDADMAC ko te kukume hiko, e meinga ai ēnei matūriki ririki kia huihui hei matūriki nui, kia taea ai te tango pai i roto i ngā tukanga whakatō, tātari rānei i muri mai.
Te tikanga flocculation o PolyDADMAC
Ko te whakapūpū tetahi o ngā mahi o te tukanga whakapūpū. E pā ana ki te tukanga e
Ko ngā "puawai konumohe iti" i hangaia i te wā o te tukanga whakapūpū ka hanga he putunga me ngā matūriki nunui mā te mimiti, te whakakore hiko, te hono me te hopu kupenga.
I roto i te umanga maimoatanga wai, ka whakarōpūtia te mimiti me te whakakore hiko hei whakapūmau, ko te piriti me te hopu kupenga ka whakarōpūtia hei whakapūmau. Ko ngā matū e rite ana ka kiia he whakapūmau me he whakapūmau.
E whakaponohia whānuitia ana e toru ngā tikanga mahi a te PolyDADMAC: te mimiti, te whakakore hiko me te piriti. Ko ngā mea tuatahi e rua ngā mea matua. Koia te take i whakarōpūtia ai te PolyDADMAC hei matū whakakōkī. Heoi, e whakaaro ana te nuinga o te tangata ko te whakakōkī me te flocculation he tukanga kotahi, nō reira ka kiia hoki a PolyDADMAC he flocculant.
I roto i ngā tukanga maimoatanga wai, ka whakamahia te PolyDADMAC hei whakapūkara hei whakapai ake i te kounga o te wai. Ina koa, ka taea e te rōpū tote ammonium quaternary cationic o te PolyDADMAC te whakaputa i te kukume hiko me ngā matūriki anionic i whakatārewatia, ngā matūriki colloidal rānei i roto i te wai, ka hua ake te whakakorenga, ka hangaia he puranga o ngā matūriki nunui ake ka whakatōngia. Ka tirotirohia ēnei puranga i te wā o te tukanga whakatō, tātari rānei hei pure i te kounga o te wai.
Ngā Painga o PolyDADMAC
Ki te whakatauritea ki ngā mea whakarewa tuku iho (konumohe, PAC, me ētahi atu), kei a PolyDADMAC ēnei painga nui e whai ake nei:
Whai hua: Ka taea e te PolyDADMAC te tango wawe i ngā poke o te wai, me te whakapai ake i te kounga o te wai.
Ngāwari ki te whakahaere: He māmā noa te whakamahi, tāpirihia noa i raro i ngā tikanga e tika ana.
Te Oranga Tonu: He pai te pumau o te PolyDADMAC, ā, kāore e tere te pakaru pērā i te polyacrylamide.
Pānga kaha o te whakapūpū: Mā te rōpū tote ammonium quaternary cationic ka hoatu he kaha kaha ki te whakapūpū i te PDMDAAC, ā, ka pai te rongoā i ngā momo āhuatanga wai;
He pai te ātete ki te tote, te ātete ki te waikawa me te kawakore: He pai te PDMDAAC mō ngā āhuatanga kounga wai uaua, ā, he pumau tonu tana mahi whakaheke i raro i te tote teitei, ngā āhuatanga waikawa, kawakore rānei;
Utu iti: He pai te rere o te wai i roto i te PolyDADMAC, ā, he iti te horopeta, ka taea ai te whakaiti i ngā utu maimoatanga wai.
He iti te paru: He iti ake te paru e whakaputaina ana e te PolyDADMAC i ngā mea whakakōkī me ngā mea whakapūkara kore-ora, ā, ka penapenahia hoki ngā utu tukatuka muri.
Te horopeta me ngā tūpato o te PolyDADMAC
I te whakamahinga o te PolyDADMAC, me āta whai i ngā tikanga whakahaere kia pai ai ngā hua maimoatanga, kia kore ai hoki e pāngia e ngā pānga taha. I te nuinga o te wā, i muri i te tāpiri i ngā flocculants pērā i te polyaluminium chloride, ka tāpirihia te PolyDADMAC kia pai ai te pānga totoka. Hei tāpiri, me whakarite tika te horopeta kia rite ki te kounga o te wai me ngā whakaritenga maimoatanga. Ka taea te whakatau i te horopeta tika mā te whakamātautau ipu.
I te katoa,PolyDADMACHe mea nui tēnei i roto i te ao o te maimoatanga wai. Mā te mārama hohonu ki ōna āhuatanga me āna whakamahinga ka āwhina i te whakamahinga whai hua o tēnei hua hei whakapai ake i te kounga o te wai me te tiaki i te taiao.
