waea whakairi: wāhanga matua i roto i te hikohiko

waea whakairohe mea nui rawa i roto i te tukanga o te hoahoa me te whakapiri i ngā ara hiko me ngā pūrere. he mea hanga i te konganuku whakarewa e he iti te wāhi rewa, me te whakamahia te nuinga mo te hanga hononga hiko i waenganui i ngā wāhanga poari ara hiko. ka tirotirohia i tēnei tuhinga tona whai wāhi i roto i te hiko

te hanganga o te waea whakairi

Ko te nuinga o te waea solder he mea hanga mai i te ranunga o nga konganuku pēnei i te tine, te mata, te hiriwa me ētahi wā he iti noa iho te rere. Ko nga konumohe e whakamahia ana ko te tine-matū (sn-pb) me nga waahanga kore-matū pēnei i te tine-whe

ngā tikanga tono

kia whakamahia ai te waea whakairi, me whakarewa e koe mā te whakamahi i te rino whakairi, me whakawera ki te pāmahana e tika ana hei whakarewa i te whakairi, engari kaua e whakangaro i ētahi atu wāhanga hiko. ka haere te whakairi wai i waenganui i ngā mata whakarewa, ka hanga i tētahi hononga haumaru, hiko, kaha hoki,

te hiranga i roto i te hikohiko

I roto i te hanga me te whakatika i ngā hikohiko, he tino hira te wātea o te waea whakairi. Ka āwhina rātou ki te hono tahi i ngā huānga maha i runga i ngā papa ara iahiko tā (PCB), e mahi ana hei kōhanga māhanga mō ngā pūrere hikohiko hou katoa i tēnei rā. I te mutunga iho, kāore e taea

Ngā Whakaaro mō te Taiao

Nā ngā āwangawanga o te taiao me te hauora kua huri ngā mana whakahaere maha ki te whakamahi i ngā konumohe rēmana kore. Ko te nuinga o ngā tono i ēnei rā kāore e whakamahi ana i te rēmana nā te mea he mōrearea, nā reira he iti te whakamahinga hei wāhanga i roto i ngā rēmana e kitea ana i ngā hua

ngā wero me ngā whakahoutanga

I te mea e haere ana ngā whakatutukitanga hangarau, ka hiahiatia he nui ake ngā whakaritenga mō ngā whakarewa. Kei te haere tonu ngā mahi ki te whakawhanake i ngā whakarewa pū (tin-wāhi-parahi) e taea ai te whakapai ake i te pono o te whakarewa, te pūmau me te whakatutuki i ngā paerewa ture.

hei whakarāpopototanga, e hiahiatia ana te waea whakairo i roto i te hikohiko nā te mea e āwhina ana i te hanga me te whakatika i ngā pūrere hiko puta noa i te ao. Ko te hanganga o te waea whakairo, ngā tikanga tono me ngā take taiao e whakaatu ana i te hiranga o te hanga o nāianei me te whanaketanga tauwhiro
