He aha te whakamahinga o te Polyacrylamide i roto i te maimoatanga wai?

Polyacrylamide(PAM) he pūmua taumaha-ngota teitei e whakamahia whānuitia ana i roto i ngā tukanga maimoatanga wai i roto i ngā mara maha. He maha ngā taumaha ngota, ngā ionitanga, me ngā hanganga hei whakatutuki i ngā āhuatanga whakamahinga rerekē, ā, ka taea hoki te whakarite mō ngā āhuatanga motuhake. Mā te whakakore hiko me te mimiti me te hono i te pūmua, ka taea e te PAM te whakatairanga i te tere o te kohikohi me te whakatō o ngā matūriki iri, hei whakapai ake i te kounga o te wai. Ka rukuhia e tēnei tuhinga ngā tono motuhake me ngā pānga o te PAM i roto i te maimoatanga wai i roto i ngā mara maha.

I roto i te maimoatanga paru o te whare, ko te PAM te nuinga e whakamahia ana mō te whakatōnga o te paru me te whakamaroke i te paru. Mā te whakakore i ngā āhuatanga hiko me te whakamahi i ngā pānga piriti mimiti, ka taea e te PAM te whakatere i te kohikohinga o ngā totoka i whakatārewatia i roto i te wai hei hanga i ngā putunga o ngā matūriki nunui. He ngāwari te whakatau me te tātari i ēnei putunga, ā, ka tangohia pai ngā poke i roto i te wai, ka tutuki ai te kaupapa o te purenga o te kounga o te wai. Mā te whakamahinga o te PAM ka taea te whakapai ake i te whai huatanga o te maimoatanga paru me te whakaiti i ngā utu maimoatanga.

I roto i te ao hanga pepa, ko te PAM te mea nui hei āwhina pupuri, hei āwhina tātari, hei whakamarara, me ētahi atu. Mā te tāpiri i te PAM, ka taea te whakapai ake i te tere pupuri o ngā whakakī me ngā muka pai i roto i te pepa, ka whakaiti i te kai o ngā rauemi mata, ka whakarei ake i te kaha tātari me te mahi maroke o te penupenu. Hei tāpiri, ka taea e te PAM te mahi hei whakaū i te polymer kore-silicon i roto i te tukanga whakama, ka whakapai ake i te mā me te kanapa o te pepa.

I roto i te maimoatanga waipara o te whare waipiro,PAMe whakamahia ana i roto i te tukanga whakamaroke paru. Mō ngā tukanga whakaputa waipiro me ngā rauemi mata rerekē me ngā tukanga maimoatanga wai para, he mea nui kia tīpakohia te polyacrylamide cationic me te ionicity me te taumaha ngota e tika ana. Ko te whakamātautau kōwhiringa mā roto i ngā whakamātautau ipu whakamātautau tētahi o ngā tikanga e whakamahia whānuitia ana.

Ko te wai para kai, me te nui o ngā mea rauropi me ngā totoka iri, me whai tikanga maimoatanga tika. Ko te huarahi tuku iho ko te whakatōpuku tinana me te whakapūtanga matū koiora. Heoi, i roto i ngā mahi whaihua, he mea nui ngā wai whakapūkara polymer mō te whakamaroke paru me ētahi atu mahi maimoatanga. Ko te nuinga o ngā wai whakapūkara e whakamahia ana i roto i tēnei tukanga he hua raupapa polyacrylamide cationic. Ko te whiriwhiri i tētahi hua polyacrylamide e tika ana me whai whakaaro ki te pānga o te huringa āhuarangi (pāmahana) ki te kōwhiringa wai whakapūkara, te whiriwhiri i te taumaha ngota me te uara utu e tika ana i runga i te rahi o te wai whakapūkara e hiahiatia ana e te tukanga maimoatanga, me ētahi atu āhuatanga. Hei tāpiri, me aro ki ngā take pēnei i ngā whakaritenga tukanga me ngā taputapu me te whakamahinga o ngā wai whakapūkara.

I roto i ngā wai para hiko me te whakakikorua hiko, ka whakamahia te PAM heiKaiwhakarewa waime te kaiwhakapūngao. Mā te whakakore i ngā āhuatanga hiko me te whakamahi i ngā pānga piriti mimiti, ka taea e te PAM te whakakotahi tere me te whakatau i ngā katote konganuku taumaha ki roto i te wai para. I roto i tēnei tukanga, me tāpiri te waikawa whanariki ki te wai para hei whakatika i te uara pH ki te 2-3, kātahi ka tāpirihia he matū whakaiti. I roto i te tāke tauhohenga e whai ake nei, whakamahia te NaOH, te Ca(OH)2 rānei hei whakatika i te uara pH ki te 7-8 hei whakaputa i ngā pūngao Cr(OH)3. Kātahi ka tāpirihia he matū whakapūngao hei whakapūngao me te tango i te Cr(OH)3. Mā roto i ēnei tukanga maimoatanga, ka āwhina te PAM ki te whakapai ake i te whai huatanga o te maimoatanga wai para hiko me te whakakikorua hiko, me te whakaiti i te kino o ngā katote konganuku taumaha ki te taiao.
