Te Whakamahinga o te Polyacrylamide i roto i te Tangohanga Koura me te Hiriwa

He tukanga uaua te tango pai i te koura me te hiriwa mai i te konganuku e hiahia ana ki te whakahaere matū tika me ngā tikanga tukatuka matatau. I roto i ngā matū maha e whakamahia ana i roto i te keri hou,Polyacrylamide(PAM) tētahi o ngā matū keri tino whai hua, ā, he whānui te whakamahinga. Nā te pai o ngā āhuatanga whakapūpū me te ngāwari ki te urutau ki ngā momo hanganga o te konganuku, he mea nui te mahi a te PAM ki te whakapai ake i te wehenga, te whakanui ake i te hua, me te whakaiti i te pānga ki te taiao puta noa i te tukanga whakaora koura me te hiriwa.

Te Mahi a te Polyacrylamide i roto i te Tukanga Tango

1. Te Whakaritenga o te Kohatu

Ka tīmata te tukanga mā te kuru me te huri i te konganuku, ā, i taua wā ka whakaitihia te konganuku mata ki te rahi o te matūriki e tika ana mō te tango. Kātahi ka konatunatua tēnei konganuku kuru ki te wai me te raima hei hanga i te paru ōrite i roto i te mira pōro. Ko te paru ka puta ko te tūāpapa mō ngā mahi whakarewa o muri mai pērā i te whakatōtō, te tango, me te mimiti.

2. Te Whakatōtō me te Whakapūtanga

Kātahi ka tāpirihia te paru ki roto i te whakamātotoru i mua i te whakarewanga. Koinei te wāhiNgā Whakarewa Polyacrylamideka tāpirihia tuatahitia. Ka āwhina ngā ngota PAM ki te here i ngā matūriki totoka pai kia kotahi, kia hanga ai he puranga nui ake, he "pūpū" rānei. Ka tere te taunga o ēnei pūpū ki raro o te tāke whakamātotoru, ka hua ake he āhua wai mārama ki runga. He mea nui tēnei taahiraa hei tango i ngā pūpū taikaha me te whakapai ake i te whai huatanga o ngā tukanga matū e whai ake nei.

3. Te Whakarewatanga o te Cyanide

I muri i te wehenga o te totoka-wai, ka uru te paru matotoru ki roto i tētahi raupapa o ngā tāke horoi. I roto i ēnei tāke, ka tāpirihia he otinga cyanide hei whakarewa i te koura me te hiriwa mai i te konganuku. Ka āwhina te PAM ki te pupuri i te ōritetanga pai o te paru, ā, ka whakapai ake i te taunekeneke i waenga i te cyanide me ngā matūriki kohuke. Mā tēnei pa atu ka whakanui ake i te pai o te horoi, ka taea ai te tiki atu i te koura me te hiriwa mai i te nui ōrite o te konganuku mata.

4. Te mimiti waro

Kia rewa ngā konganuku utu nui ki roto i te wairewa, ka rere te paru ki roto i ngā tāke mimiti waro. I tēnei wāhanga, ka mimiti te waro whakahohe i te koura me te hiriwa kua rewa mai i te wairewa. Mā te whakamahinga o te polyacrylamide ka whakarite kia rere ōrite te paru, kia kore ai e ārai, kia pai ake ai te whakaranu me te mimiti mōrahi. Ko te pai ake o tēnei whakapā, ko te teitei ake o te tere whakaora o ngā konganuku utu nui.

5. Te Whakakorenga me te Whakaora Konganuku

Kātahi ka wehea te waro kua utaina ki te konganuku, ka whakawhitia ki tētahi pūnaha whakapūtanga, ka tangohia te koura me te hiriwa mai i te waro e te wai wera rawa, e te otinga cyanide caustic rānei. Ko te otinga kua kohia, he nui nei ngā katote konganuku, ka tukuna ki tētahi whare whakarewa hei whakamahine anō. Ko te toenga o te paru—e mōhiotia whānuitia ana ko ngā para—ka whakawhitia ki ngā puna para. I konei, ka whakamahia anō te PAM hei whakatau i ngā totoka e toe ana, hei whakamārama i te wai, hei tautoko i te rokiroki haumaru, ā-taiao hoki o ngā para maina.

Ngā Painga o te Whakamahi i te Polyacrylamide i roto i te Keri Koura

✅ He nui ake ngā hua tango

E ai ki ngā rangahau arotautanga tukanga keri, ka taea e ngā mea whakarewa polyacrylamide te whakanui ake i te tere whakaora o te koura me te hiriwa mā te neke atu i te 20%. Mā te pai ake o te whai huatanga o te wehenga ka nui ake te putanga whakarewa me te whakamahinga pai ake o ngā rauemi konganuku.

✅ Wā Tukatuka Tere ake

Mā te whakateretere i te whakatōtō me te whakapai ake i te rere o te paru, ka āwhina te PAM ki te whakaiti i te wā pupuri i roto i ngā whakamātotoru me ngā tāke. Ka taea e tēnei te arahi ki te tukatuka tere ake tae atu ki te 30%, te whakapai ake i te putanga mahi me te whakaiti i te wā kore mahi.

✅ He iti te utu, he pumau hoki

Mā te whakamahi i te polyacrylamide ka whakaitihia te nui o te cyanide me ētahi atu matū e hiahiatia ana, ka whakaitihia ngā utu matū. Hei tāpiri, mā te whakapai ake i te hangarua wai me te iti o te tukunga matū ka whai wāhi ki ngā mahi keri taiao-pūmau, ka āwhina i ngā mahi ki te whakatutuki i ngā ture a te kāwanatanga me ngā paerewa taiao.
