Me pēhea te whiriwhiri i te momo polyacrylamide?

Polyacrylamide(PAM) ka taea te whakarōpū i te nuinga o te wā ki te anionic, cationic, me te nonionic e ai ki te momo katote. Ko te nuinga o te wā ka whakamahia mō te flocculation i roto i te maimoatanga wai. I te wā e whiriwhiri ana, ka taea e ngā momo wai para rerekē te whiriwhiri i ngā momo rerekē. Me whiriwhiri e koe te PAM tika e ai ki ngā āhuatanga o tō wai para. I taua wā anō, me whakamārama hoki koe i roto i te tukanga ka tāpirihia te polyacrylamide me te kaupapa e hiahia ana koe ki te whakatutuki mā te whakamahi.

Ko ngā tohu hangarau o te polyacrylamide ko te taumaha ngota ngota, te nui o te waikura, te ionitanga, te matotoru, te ihirangi monomer toenga, me ētahi atu. Me whakamārama ēnei tohu i runga i te wai para e tukatukahia ana e koe.

1. Taumaha/mātotorutanga ngota

He maha ngā taumaha ngota o te polyacrylamide, mai i te iti ki te tino teitei. Ka pā te taumaha ngota ki te mahi a ngā polymer i roto i ngā tono rerekē. Ko te polyacrylamide taumaha ngota teitei te nuinga o te wā he pai ake i roto i te tukanga flocculation nā te mea he roa ake ō rātou mekameka polymer, ā, ka taea te hono i ngā matūriki maha atu.

He tino teitei te matotoru o te otinga PAM. Ina pumau te ionization, ka nui ake te taumaha ngota o te polyacrylamide, ka nui ake te matotoru o tōna otinga. Nā te mea he roa, he angiangi te mekameka macromolecular o te polyacrylamide, ā, he tino nui te ātete ki te nekehanga i roto i te otinga.

2. Te taumata o te waikura me te ionitanga

He nui te awe o te ionitanga o te PAM ki tōna pānga whakamahinga, engari ko tōna uara tika e whakawhirinaki ana ki te momo me te āhua o te rauemi e tukatukahia ana, ā, he rerekē ngā uara tino pai i roto i ngā āhuatanga rerekē. Ina teitei te kaha ionitanga o te rauemi e tukatukahia ana (he nui ake ngā mea kore-waro), me teitei ake te ionitanga o te PAM e whakamahia ana, ki te kore me iti iho. Ko te tikanga, ko te tohu o te anion e kiia ana ko te tohu o te waikura, ā, ko te tohu o te ion e kiia ana ko te tohu o te cation.

Me pēhea te whiriwhiri i te polyacrylamidee whakawhirinaki ana ki te kukū o ngā kōrori me ngā totoka iri i roto i te wai. Whai muri i te mārama ki ngā tohu o runga ake nei, me pēhea te whiriwhiri i tētahi PAM e tika ana?

1. Kia mārama ki te pūtake o te paru

Tuatahi, me mārama tātou ki te pūtake, te āhua, te hanganga, te nui o te totoka, me ētahi atu mea o te paru.

Ko te tikanga whānui, ka whakamahia te polyacrylamide cationic hei rongoā i te paru waro, ā, ka whakamahia te polyacrylamide anionic hei rongoā i te paru kore-waro. Ina teitei te pH, kaua e whakamahia te polyacrylamide cationic, ā, ina teitei te pH, kaua e whakamahia te polyacrylamide anionic. Nā te kaha o te waikawa, kāore e pai te whakamahi i te polyacrylamide anionic. Ina nui te ihirangi totoka o te paru, ka nui te polyacrylamide e whakamahia ana.

2. Te kōwhiringa o te ionitanga

Mō te paru e hiahia ana kia whakamaroketia i roto i te maimoatanga paru, ka taea e koe te whiriwhiri i ngā flocculants me ngā momo ionicity mā roto i ngā whakamātautau iti hei whiriwhiri i te polyacrylamide tino tika, ka taea ai te whakatutuki i te pānga flocculation pai rawa atu me te whakaiti i te horopeta, ka penapena utu.

3. Te kōwhiringa o te taumaha ngota

I te nuinga o te wā, ko te teitei ake o te taumaha ngota o ngā hua polyacrylamide, ko te nui ake o te matotoru, engari i te whakamahinga, ko te teitei ake o te taumaha ngota o te hua, ko te pai ake o te pānga whakamahinga. I roto i te whakamahinga motuhake, me whakatau te taumaha ngota tika o te polyacrylamide i runga i te ahumahi tono tuturu, te kounga wai me ngā taputapu maimoatanga.

Ina hoko koe, ka whakamahi hoki i te PAM mō te wā tuatahi, me whakarato koe i te āhuatanga motuhake o te paru ki te kaihanga flocculant, ā, ka tūtohu mātou i tētahi momo hua e tika ana mōu. Me tuku mai hoki he tauira mēra hei whakamātautau. Mena he nui ō wheako ki te maimoatanga paru, ka taea e koe te kōrero mai ki a mātou i ō whakaritenga motuhake, i ngā mara tono, me ngā tukanga, ka taea rānei te tuku tika mai i ngā tauira PAM e whakamahia ana e koe i tēnei wā, ā, ka honoa e mātou te polyacrylamide tika ki a koe.
