Me pēhea te tāpiri i te PAM

He pūhui raina te Polyacrylamide (PAM) me te flocculation, te adhesion, te whakaiti i te toia, me ētahi atu āhuatanga. HeiPūhui Whakapūkara Waro Polymer, e whakamahia whānuitia ana i roto i te mara o te maimoatanga wai. I te whakamahinga o te PAM, me whai i ngā tikanga whakahaere tika hei karo i te moumou matū.

Tukanga Tāpiri PAM

MōPAM totoka, me tāpiri ki te wai i muri i te whakarewatanga. Mō ngā āhuatanga wai rerekē, me whiriwhiri ngā momo PAM rerekē, me te whakataurite i ngā otinga ki ngā kukū rerekē. I te tāpiri i te polyacrylamide, me aro ki ngā āhuatanga e whai ake nei:

Ngā Whakamātautau Ipu:Whakatauhia ngā whakaritenga me te inenga pai rawa atu mā roto i ngā whakamātautau ipu. I roto i te whakamātautau ipu, āta whakanuia te inenga o te polyacrylamide, tirohia te pānga o te flocculation, ka whakatau i te inenga tino pai.

Te whakarite i te otinga wai PAM:I te mea he nui ake te taumaha ngota o te PAM anionic (APAM) me te PAM kore-ionic (NPAM) me te kaha ake, ka hangaia te polyacrylamide anionic ki roto i te otinga wai me te kukū o te 0.1% (e pā ana ki te ihirangi totoka) me te wai kore tote, ma. Kōwhiria he peere enamel, he konumohe kua whakakikoruatia, he peere kirihou rānei hei utu mō te rino, nā te mea ka whakaterehia e ngā katote rino te pirau matū o ngā PAM katoa. I te wā e whakarite ana, me tauhiuhi ōrite te polyacrylamide ki roto i te wai whakaoho, ā, me whakamahana tika (<60°C) kia tere ake ai te whakarewa. I te wā e whakarewahia ana, me aro ki te tāpiri i te hua kia ōrite, kia āta haere ki roto i te whakarewa me ngā mahi whakaoho me te whakamahana kia kore ai e totoka. Me whakarite te otinga i te pāmahana e tika ana, ā, me karo i te kutikuti miihini roa me te kaha. E taunakihia ana kia huri te mīhini whakaranu i te 60-200 rpm; ki te kore, ka pakaru te polymer, ā, ka pā ki te pānga whakamahinga. Kia mahara me whakarite tonu te otinga wai PAM i mua i te whakamahinga. Mā te rokiroki roa ka heke haere te mahi. I muri i te tāpiri i te otinga wai flocculant ki te whakatārewatanga, mā te whakaoho kaha mō te wā roa ka whakangaro i ngā floc kua hangaia.

Ngā Whakaritenga Inenga:Whakamahia he taputapu ine hei tāpiri i te PAM. I te tīmatanga o te tauhohenga o te tāpiri i te PAM, me whakanui ake i te tūponotanga o te pānga o ngā matū ki te wai e tukatukahia ana, me whakanui ake i te whakaoho, me whakanui ake rānei i te tere rere.

Ngā Mea hei Mātakitaki Ina Tāpirihia te PAM

Wā Whakakorenga:He rerekē ngā wā memeha o ngā momo PAM rerekē. He poto noa te wā memeha o te PAM cationic, he roa ake ia te wā memeha o te PAM anionic me te PAM non-ionic. Mā te whiriwhiri i te wā memeha tika ka āwhina i te whakapai ake i te pānga o te flocculation.

Te Inenga me te Kukū:Ko te horopeta tika te mea nui hei whakatutuki i te pānga pai rawa atu o te whakapūpū. Mā te nui rawa o te horopeta ka nui rawa te whakapūpū o ngā korori me ngā matūriki iri, ka hanga he paru nui hei utu mō ngā whakapūpū, ā, ka pā ki te kounga o te para.

Ngā Tikanga Whakaranu:Hei whakarite kia pai te whakaranu o te PAM me te wai para, me whiriwhiri ngā taputapu me ngā tikanga whakaranu e tika ana. Tērā pea ka kore e tino memeha te PAM i te whakaranunga ōrite, ā, ka pā ki tōna pānga ki te rere o te wai.

Ngā Āhuatanga Taiao o te Wai:Ka pāngia hoki te pānga o te rere o te PAM e ngā āhuatanga taiao pēnei i te pH, te pāmahana, te pēhanga, me ētahi atu. I runga i ngā āhuatanga kounga o te wai para, me whakarerekē pea ēnei tawhā kia pai ai ngā hua.

Raupapa Inenga:I roto i tētahi pūnaha inenga maha-kaitātari, he mea nui kia mārama ki te raupapa inenga o ngā momo kaitātari. Tērā pea ka pā te raupapa inenga hē ki te taunekeneke i waenga i te PAM me ngā korori me ngā matūriki iri, ā, ka pā ki te pānga o te rere o te wai.

PolyacrylamideHe pūmua maha ngā whakamahinga o te (PAM) me ngā momo whakamahinga, inā koa i roto i te maimoatanga wai. Hei whakanui ake i tōna whai huatanga me te karo i te moumou moni, he mea nui kia whai i ngā tikanga whakahaere tika. Mā te āta whakaaro ki ngā āhuatanga pēnei i te wā whakarewa, te inenga, ngā āhuatanga whakaranu, ngā āhuatanga taiao wai, me te raupapa inenga, ka taea e koe te whakamahi pai i te PAM hei whakatutuki i ngā hua flocculation e hiahiatia ana me te whakapai ake i te kounga o te wai.
