Te Whakapiri Piki me te Horoi Whakarewa Hiko

He mahi noa te whakarewa i te kowiri tira puta noa i ngā ahumahi pēnei i te hanga, te hinu matū, te moana, te tukatuka kai, me te whakaputa hiko. Heoi, i muri i te whakarewa, ka ngaro te paparanga tiaki o te rohe e pāngia ana e te wera (HAZ) i runga i ngā mata o te kowiri tira, ka waiho hei mea ngoikore ki te waikura me te tae ke. Hei whakaora i te ātete ki te waikura me te whakatutuki i te whakaotinga ma, ngaio, he mea nui te horoi whakarewa.

Ko ngā tikanga horoi whai muri i te whakarewa e whakamahia whānuitia ana kowhakapiri pīkaramete horoi whakarewa hikoAhakoa ko te whāinga o ēnei tikanga e rua he whakaora i te kounga o te mata o te maitai kore waikura, he rerekē te tukanga, te whai huatanga, te haumaru, me te pānga ki te taiao. He mea nui te mārama ki ēnei rerekētanga hei whiriwhiri i te tikanga horoi tika.

He aha te Whakapiri Piki?

He otinga matū te whakapiri pīkara i hangaia i ngā waikawa kaha pērā i te waikawa hauota (HNO₃) me te waikawa hauwaiwai (HF). Ka pania tika ki te wāhi whakarewa mā te whakamahi i te paraihe, i te spatula rānei. Ka tangohia e ngā matū te tae wera, ngā waikura, me te unahi mā te whakarewa i tētahi paparanga angiangi o te mata o te maitai kore waikura.

Ngā Āhuatanga Matua o te Whakapiri Piki

• He whai hua ki te tango i ngā waikura me te tae wera.

• Ka whakaora i te paparanga waikura chromium kore mahi.

• He pai mō ngā wāhi whakarewa nui, kāore i te tino tika te hanganga.

• Me horoi pai ki te wai i muri i te whakamahinga.

Ahakoa he whai hua, he tino waikura te whakapiri pīkara, ā, me tino tupato ki ngā mahi haumaru i te wā e whakamahia ana.

He aha te Horoi Whakarewa Hikohiko?

Ko te horoi whakarewa hikohiko, e mōhiotia ana ko te horoi hikohiko, he tikanga hou e whakamahi ana i te iahiko hiko me te otinga irahiko ngawari hei horoi i ngā whakarewa. Mā te paraihe waro, muka rānei, e piri ana ki te mīhini, ka tukuna te iahiko ki te mata whakarewa.

Ngā Āhuatanga Matua o te Horoi Whakarewa Hikohiko

• Ka tango i te rerekētanga o te tae, ka whakaora anō i te paparanga kore mahi.

• Ka puta he āhua kanapa, oro.

• Kāore he auahi kino e puta mai ana i te whakarite ki te whakapūkara matū.

• He tukanga tere ake, haumaru ake hoki mō ngā kaiwhakahaere.

Kei te piki haere te rongonui o tēnei tikanga nā tōna whai huatanga, te haumaru, me te āhua pai ki te taiao.

Te Whakapiri Piki me te Horoi Whakarewa Hikohiko: He Whakataurite

1. Te Whai Hua o te Horoi

Te Kōwhiri i te Tikanga Tika

Ko te kōwhiringa i waenga i te whakapiri pīkara me te horoi whakarewa hiko e whakawhirinaki ana ki ētahi āhuatanga:

• TahuaMō ngā kaupapa iti te utu, he pai ake te whakamahi i te whakapiri pīkara.

• Haumaru i te Wāhi MahiKo te horoi hiko te kōwhiringa pai ake.

• Ngā Ture TaiaoKo ngā ture pakari ake e akiaki ana i ngā kamupene ki ngā tikanga hikohiko.

• Ngā Whakaritenga MataMō ngā whakaotinga oro, he mea tino pai te horoi hiko.

• Tauine KaupapaKo te hanga nui-rahi ka whakawhirinaki pea ki te whakapūkara, engari ko ngā ahumahi tino-tika e pai ake ana ki te hikohiko.

Whakamutunga

Ngā mea e ruawhakapiri pīkaramete horoi whakarewa hikoHe mea nui te mahi a ngā mea nei ki te pupuri i te ātete ki te waikura me te āhua o ngā whakarewa maitai kore waikura. Ahakoa he whai hua, he ōhanga hoki te whakapiri pīkara mō ētahi mahi, he huarahi hou, haumaru, me te pai ki te taiao te horoi whakarewa hiko e tutuki ai ngā paerewa ahumahi me te taiao o ēnei rā.

Me arotake e ngā kaihanga ngā whakaritenga o ā rātou kaupapa, ngā kaupapa matua mō te haumaru, me te taiao ture kia tika ai te whiriwhiri.

Hei kaiwhakarato maitai kore waikura o te ao,sakysteele whakatairanga ana i ngā otinga horoi whakarewa haumaru, whai hua hoki mō āna kiritaki. Mā te whakatenatena i te whakamahi i ngā tikanga matatau pēnei i te horoi whakarewa hikohiko, me te tautoko tonu i ngā tikanga tuku iho ina hiahiatia,sakysteelkia whakarite kia whiwhi ngā kiritaki i ngā hua me ngā ratonga e pakari ana, e tutuki ana i ngā whakaritenga, ā, e mau tonu ana hoki.

I roto i te ao hurihuri o te hanga maitai kore waikura, ka tonu te huri ki ngā otinga hoa-taiao me te mahi-teitei ki te hanga i te heke mai o te horoi whakarewa.
