Kāore e taea te whakamahi i te maitai kore waikura me te maitai waro i te wā e pā tika ana, he kaupapa nui tēnei i roto i te pūtaiao rauemi me te mahi hangarau. Nā te puta o te "waikura karawaka", e mōhiotia whānuitia ana ko te "waikura karawaka" me te "waikura konganuku rerekē" te take matua. He rite tēnei ki tētahi wahi maitai waro e patu ana i a ia anō hei tiaki i te maitai kore waikura, ka tere ai te waikura o te maitai waro.
Kāore e taea e te kowiri tira te ōrite ki te matua o te maitai waro, ko te take: te waikura konukōre
1. Ko te rerekētanga pūmanawa te kaha akiaki
He rerekē ngā mahi hikohiko o ngā konganuku rerekē i roto i ngā irahiko (pērā i te wai, te hau makuku, ngā waikawa, ngā kawakore, ngā tote, me ētahi atu), e taea ai te mārama ko ō rātou taumata rerekē o te ngaronga irahiko. Ka inehia tēnei rerekētanga o te mahi mā te pūmanawa irahiko.
He iti ake ngā pūmanawa irahiko o ngā konganuku tauhohe, pērā i te maitai waro, ā, he ngāwari ake te ngaro o ngā irahiko, ka kore ai e ātete ki te waikura.
He nui ake ngā pūmanawa hikohiko o ngā konganuku kore mahi (pērā i te maitai kore waikura), ā, he iti ake te tūponotanga ka ngaro ngā irahiko. Ko te take he "kowiri tira" te maitai kore waikura, nā te mea ka hangaia e te chromium i runga i tōna mata he kiriata whakangāwari chromium oxide matotoru, e ārai ana i te waikura anō.
Ina pā tika ēnei konganuku e rua ki te electrolyte, ka hangaia he ara iahiko pākahiko tuatahi katoa.
2. Te tukanga waikura
Anode (pito waikura): Ko te maitai waro, hei konganuku hohe, ka noho hei anode o te pākahiko. Ka waikura kaha (ka waikura) ka tukuna ngā irahiko. Ko te tauhohenga ko: Fe → Fe² ⁺+2e ⁻
Katote (pito tiaki): Ko te maitai kore waikura, hei konganuku kore mahi, ka noho hei katote o te pākahiko. Kāore e waikura, engari ka whiwhi noa i ngā irahiko e rere ana mai i te anote, ā, ka whakamahia ēnei irahiko hei tauhohe ki ngā irahiko (pērā i te hāora i roto i te wai). Ko te tauhohenga ko: O₂+2H₂ O+4e⁻ → 4OH⁻
Hua: I roto i tēnei pūnaha pākahiko, ka rere te iahiko mai i te maitai waro (anode) ki te maitai kore waikura (cathode), ka piki ake te tere o te waikura o te maitai waro, ko te maitai kore waikura ia e tiakina ana e te "tiaki cathodic" ā, kāore rawa e waikura.
He kupu whakarite oraora:
He rite ki te whai hoa mahi a te "tangata pono" (te maitai waro) me te "tangata mohio" (te maitai kore waikura). Ina pāngia e ngā uauatanga (te taiao waikura), ka patu tonu te hunga pono i ō rātou ake painga (kia waikura) kia kore ai e whara te hunga mohio.
Kāore e taea e te kowiri tira te ōrite ki ngā āhuatanga matua o te maitai waro
Ko te kaha o te waikura galvanic e whakawhirinaki ana ki ngā āhuatanga e whai ake nei:
Taiao (irahiko):Koinei te mea tino nui. I te hau maroke, kāore e puta te waikura konukōre nā te mea kāore he irahiko e hanga ana i tētahi ara iahiko. Engari i ngā taiao makuku, i te wai moana, i ngā wāhi ahumahi, me ngā taiao rehu tote, ka tino tere, ka tino kino hoki te waikura.
Rerekētanga pūmanawa:Ko te nui ake o te rerekētanga pūmanawa i waenga i ngā konganuku e rua, ko te kaha ake o te kaha akiaki mō te waikura. He nui te rerekētanga pūmanawa i waenga i te maitai waro me te maitai kore waikura hei whakaputa waikura nui.
Te ōwehenga o te horahanga anode ki te horahanga cathode:Koinei tētahi o ngā āhuatanga tino morearea. Mēnā he nui te horahanga o te katote (te maitai kore waikura) ā, he iti te horahanga o te anote (te maitai waro), ka tino kukū te ia waikura ki runga i te maitai waro iti, ka waikura katoa, ka pokaia hoki i roto i te wā poto rawa. Hei tauira, mēnā ka mau te tāke maitai kore waikura ki te pūtu maitai waro, ka tere te waikura me te pakaru o te pūtu maitai waro.
Me pēhea te ārai me te whakaoti i te hononga o te kowiri tira ki te maitai waro?
I roto i ngā mahi whaihua, me hono pinepine te maitai kore waikura me te maitai waro, ā, me mahi ngā mahi wehewehe:
1. Te ārai hiko:Koinei te tikanga tino whai hua, ā, ko te tikanga e whakamahia whānuitia ana. Tāpirihia he rauemi ārai kore-arataki hiko ki waenganui i ngā konganuku e rua hei tapahi i te ara iahiko.
- Whakamahia ngā kēkete/ngā horoi whakamahana: Whakamahia he kirihou (pēnei i te PVC, te nairona), te rapa, ngā kēkete hangai rānei ki ngā hononga flange.
- Whakamahia ngā pū me ngā whakakākahu whakamahana: Mō ngā hononga pū, whakamahia ngā pū kirihou i waenganui i ngā pū me ngā kōhao maitai waro, ā, whakamahia ngā whakakākahu whakamahana i raro i ngā nati.
- Paparanga whakawehe paninga: Rehuhia te kapia epoxy, peitahia, whakamahia rānei ētahi atu paninga ki te mata e pā ana. E taunakihia ana kia pania ngā mea e rua, kia pania rānei te mata cathode (te maitai kore waikura), nā te mea ki te pania te anode (te maitai waro) anake, ina pakaru te paninga, ka nui haere te waikura i te wāhi kua pakaru.
2. Taiao whakahaere:Kia maroke, kia ma hoki ngā wāhanga hononga kia kore ai e kohia ngā irahiko.
3. Te whakamahi i ngā rauemi whakawhiti:te tāpiri i tētahi konganuku he pūmanawa hiko kei waenganui i ngā konganuku e rua (pērā i te konumohe), engari kāore i te tino whakamahia tēnei tikanga, ā, me āta hoahoa.
4. Te tiakitanga katote:Ka hurihia te hanganga katoa hei katote mā te whakamahi i te iahiko o waho, mā te patu rānei i te anote (pērā i te poraka konutea), engari he mea whakamahi tēnei mō ngā hanganga nunui pērā i ngā kaipuke me ngā paipa.
Whakamutunga
Kāore e taea te pa atu o te maitai kore waikura me te maitai waro nā te mea ka taea e rāua te hanga pākahiko tuatahi i roto i ngā taiao irahiko makuku, ka tere ake te waikura o te maitai waro hei anode. Hei karo i tēnei āhuatanga, me mahi ngā mahi wehewehe hiko i te wā hoahoa me te tāutanga, pērā i te whakamahi i ngā gaskets whakamahana, ngā pū, me ngā paninga, kia mau ai te haumaru me te roa o te ora o ngā taputapu.
