Te Pānga o ngā Wāhanga Granite ki te Mana Kounga PCB.

 

I roto i te ao hanga hikohiko e whanake tonu ana, he mea nui te whakahaere kounga o ngā papa hikohiko tānga (PCB). Ko tētahi mea e warewarehia ana, ā, he pānga nui ki te kounga o te PCB ko te whakamahinga o ngā wāhanga karāhe i roto i te tukanga hanga. E mōhiotia ana mō tōna pakari me tōna pumau, he mea nui te karāhe ki te whakarite i te tika me te tika o te hanga PCB.

Ko ngā wāhanga karāhe, pērā i ngā tēpu tirotiro me ngā taputapu whakapūmau, ka whakarato i tētahi mata pumau, papatahi hoki, he mea nui mō te whakarite me te huihuinga o ngā PCB. Ko ngā āhuatanga tūturu o te karāhe, tae atu ki tōna ātete ki te horapa wera me te wiri, ka whai wāhi ki tētahi taiao hanga pumau ake. He mea nui tēnei pumau hei pupuri i ngā ātete pakari e hiahiatia ana mō ngā taputapu hiko hou, nā te mea ahakoa he iti noa te pekanga ka arahi ki ngā raruraru mahi, ki te rahunga rānei o te hua.

Hei tāpiritanga, mā te whakamahi i te karāhe i roto i te tukanga whakahaere kounga ka pai ake te tika o ngā inenga i mahia i te wā tirotiro. Mā ngā taputapu ine tino tika, ina whakatakotoria ki runga i te mata o te karāhe, ka whakaitihia ngā hapa i puta mai i ngā hapa o te mata. Ka hua ake tēnei i ngā raraunga pono ake, ka taea e ngā kaihanga te kite wawe i ngā hapa i roto i te huringa whakaputa me te whakatinana i ngā mahi whakatika i te wā tika.

Hei tāpiritanga, he ngāwari te horoi me te tiaki i ngā wāhanga o te karāhe, he mea nui tēnei i roto i te taiao hangahanga ka pāngia te kounga o te PCB e ngā poke. Ko te āhua kore-pūpū o te karāhe ka ārai i te mimiti o te puehu me ngā matū, ka whakarite kia noho parakore te mata, kia pai ai te hanga kounga teitei.

Hei whakamutunga, kāore e taea te whakaiti i te pānga o ngā wāhanga karāhe ki te whakahaere kounga PCB. Mā te whakarato i tētahi taiao pumau, tika, me te ma mō te hanga me te tirotiro, he mea nui te karāhe ki te whakapai ake i te kounga whānui o ngā PCB. I te mea kei te tipu haere tonu te hiahia mō ngā hua hiko mahi-teitei, he mea nui te haumi ki ngā otinga e hangai ana ki te karāhe mō ngā kaihanga e whai ana ki te pupuri i tētahi painga whakataetae me te whakarite i te pono o te hua.
