Ngā Tikanga me ngā Tikanga Whakakorenga PAM: He Aratohu Ngaio

Polyacrylamide(PAM), hei mea nui mō te maimoatanga wai, e whakamahia whānuitia ana i roto i ngā momo ahumahi. Heoi, he uaua pea te whakarewa i te PAM mō te tini o ngā kaiwhakamahi. Ko ngā hua PAM e whakamahia ana i roto i ngā wai para ahumahi e rua ngā momo: te paura maroke me te paura whakapūkara. Ka whakamāramahia e tēnei tuhinga te tikanga whakarewa o ngā momo PAM e rua kia tino whiwhi ai ngā kaiwhakamahi i ngā hua pai rawa atu i roto i ngā mahi tūturu.

 Paura Maroke Polyacrylamide

Ko te tikanga whakarewa tika te tikanga whakarewa PAM māmā rawa, ā, ko te tikanga whakarewa PAM tino noa. He pai tēnei tikanga mō te paura PAM he iti ake te taumaha ngota, ā, he ngāwari hoki te whakarewa. Anei ngā mahi motuhake:

Whakaritea te Ipu: Kōwhiria he ipu kirihou ma, maroke, pakari, he nui hei pupuri i te paura PAM me te wai e hiahiatia ana. Kaua e whakamahi i ngā ipu whakarewa, i ngā ipu rānei he paru whakarewa.

Tāpirihia te Whakarewa: Tāpirihia te nui o te wai e tika ana.

Te Whakaoho: Tīmatahia te whakaoho. I te wā e whakaoho ana, kia tino rumakina te whakaoho ki roto i te wairewa kia kore ai e puta he mirumiru. Kaua e tere rawa te whakaoho kia kore ai e whati te mekameka ngota PAM.

Tāpirihia te Paura PAM: Tāpirihia mārire te paura PAM e hiahiatia ana ki roto i te ipu, me te whakaoho mārire kia kore ai e rere te puehu. Me whakaoho tonu te wairewa kia marara ōrite te paura PAM i roto i te wairewa.

Taria kia Rewa: Me whakaoho tonu, me te tirotiro i te memeha o te paura PAM. I te nuinga o te wā, me whakaoho mō te 1 ki te 2 hāora tae noa ki te memeha katoa o te paura PAM.

Tirohia te Wairewatanga: Kia oti te whakarewatanga, tirohia mēnā kua rewa katoa mā te tirotiro i te māramatanga, te taupū whakaata rānei o te otinga. Mēnā ka puta mai he matūriki, he puranga rānei kāore anō kia rewa, me whakaoho tonu kia rewa katoa. Mēnā he nui rawa te taumaha ngota o te PAM, ā, he puhoi rawa te whakarewatanga, ka taea hoki te whakamahana tika, engari kaua e neke ake i te 60°C.

Emulsion Polyacrylamide

Whakaritea te Ipu me ngā Utauta: Kōwhiria he ipu nui kia nui ai te wāhi hei whakaranu. Kia rite mai he mea whakaoho, he rākau whakaoho rānei hei whakarite kia pai te ranunga o te wai.

Whakaritea te Otinga: Tāpirihia te wai me te wai whakapūkara PAM i te wā kotahi, ka tīmata i te whakaoho i te wā kotahi kia tino whakaranua te wai whakapūkara me te wai.

Whakahaerehia te Kukū Whakamutunga: Me whakahaere te kukū whakamutunga o te PAM emulsion i te 1-5% kia pai ai te pānga o te flocculation. Mena me whakarerekē te kukū, tāpirihia tonutia te wai, whakanuia rānei te PAM emulsion.

Me Whakaoho Tonu: Whai muri i te tāpiri i te wai whakapūkara PAM, me whakaoho tonu te wai mō te 15-25 meneti. Mā tēnei ka āwhina i ngā ngota PAM kia marara katoa, kia memeha hoki, kia ōrite ai te tohatoha i roto i te wai.

Kaua e Whakaohokia Nui rawa: Ahakoa ka āwhina te whakaoho tika ki te whakarewa i te PAM, mā te whakaoho nui ka pakaru pea ngā ngota PAM, ka whakaiti i tōna pānga pupuhi. Nō reira, whakahaeretia te tere me te wā whakaoho.

Te Rokiroki me te Whakamahinga: Rokirokihia te otinga PAM kua whakarewaina ki te wāhi pōuri, maroke, me te whakarite kia tika te pāmahana. Āta karohia te whiti tika o te rā hei ārai i te pirau o te PAM. I te wā e whakamahia ana, me whakarite kia ōrite te otinga kia kore ai e pāngia te pānga o te rere o te wai nā te kore e taurite te tohatoha.
