I te wā o ngā raruraru hangarau tere, ko ngā papa arawhiti tā (PCBs) he wae kaurori puta noa i ngā mahi hangarau tiketike. Na te tōnuitanga o ngā hangarau puta noa, he tokomaha nga taiete me ngā kaihanga e tono ana i ngā RW kōrero i whakaritea ki ā rātou whakaritenga āwhina. Mā tēnei e tohu ai he awhe o ngā kupumatua tūturu: Ratonga Tā Arawhiti, PCB Ritenga, Tā PCB Ritenga, PCB Maker, me te Kamupene Hanga PCB.
Ko ngā ratonga tā arawhiti e whakarato ana i ngā kōwhiringa tino pai, te whakangāwari i ngā whakarerekētanga i runga anō i ngā hoahoa arawhiti me ngā whakaritenga tāuke. I te whenua hangarau hihiri o tēnei rā, ka waea ngā hua me ngā pūrere mō ngā tawhā hoahoa motuhake e uaua ana ngā PCBs paerewa ki te whakaae. I a ia e ārai ana i te PCB ritenga, ka tukuna e ngā ratonga tā arawhiti he rongoā hei whakatau i ngā hiahia me ngā aronuinga, ngā papa arawhiti pūkaha. Mā ngā ratonga tā arawhiti ka taea e ngā kiritaki te whiwhi i te whakakā PCB kua whakaritea katoatia ki ā rātou whakaritenga ahurei. Ka whakawhiwhia e ngā PCBs ritenga ngā painga i a rātou e pupuri ana i ngā tohutohu tauwhāiti e pā ana ki te tahora arawhiti, ngā ahu, ngā rauemi, me ngā pūkenga, mā reira e arotau ana i te mahinga arawhiti me te tika. Tērā anō, ko te tā PCB ritenga e whai ana i ngā hoahoa arawhiti tāuke o ngā kiritaki i runga i ngā PCBs. Mā te tā PCB ritenga, ka taea e ngā kiritaki te huri i ō rātou ariā arawhiti pukapuka hei hua taumahinga, hāngai hoki.
Hei whiwhi i ngā PCBs kōrero, ngā kamupene me ngā kaihanga e rapu noa ana i ngā hoa pūkenga, i runga anō i ngā kaihanga PCB me ngā kamupene mahi PCB. Ko ngā kaihanga PCB ko ngā pūhātū PCB e whai tohunga ana me te whaina hangarau hei whakakā i ngā rongoā PCB kua whakaritea i runga anō i ngā paearu o ngā kiritaki. Ko ngā kaihanga PCB mokatere-tuatahi e whakamanamana ana i ngā taputapu whakanao tapa-tapa me ngā tukanga, i whakapakaritia e ngā tīma tau e whakauru ana ki ngā kiritaki ki te whakawātea i ā rātou whāinga me te whakarato rongoā tino pai. Ināianei, ko ngā kamupene hanga PCB e tohu ana i ngā pākihi e whakauru ana ki te whakanao PCB, i te nuinga o te wā, ko te tikanga kia rāhuitia ki ngā whiwhinga mahi whakamutunga me ngā arotaupū kounga pākaha, me te whakarite i ngā tūemi PCB ōrite, pono hoki. Hei wahanga o te pūnaha whakanao PCB, kāore ngā kamupene PCB e whakarite anake i ngā ratonga whakakā PCB kua whakaritea, engari ka homai hoki he āwhina hangarau me te tautoko hoko ā muri hei whakaū i te ngātahitanga pakari o ngā kiritaki.
Ka whakaae te tā PCB ritenga mō te tā i ngā tahora arawhiti ahurei ki ngā papa PCB i runga anō i ngā whakaritenga motuhake a ia kiritaki. Mā te whakawhiti i ngā ratonga tā PCB ritenga, ka taea e ngā taiete me ngā kaihanga te huri i ō rātou whakaaro arawhiti pukapuka hei hua taumahinga kua whakaritea mō ā rātou taupānga. Mā te tukanga tā PCB ritenga e taea ai e ngā kaihanga PCB te whakakā i ngā papa me ngā hoahoa arawhiti tāuke e tūtaki ana i ngā whakaritenga hiko, ā-tinana hoki.
Mā ngā ratonga tā PCB ritenga mai i ngā kamupene hanga PCB, ka taea e ngā kiritaki te tiki i ngā PCBs kua whakaritea mō ngā take pēnei:
- Tahora Arawhiti hei arotau i te mahinga
- Ngā ahu me te hanga o te Poari hei whakauru
- Ngā rauemi motuhake hei aro atu ki ngā here
- Ngā pūkenga Fabrication mō te whaikikotanga
Ko te whānuitanga o ngā ratonga tā arawhiti e whakamana ana i ngā kiritaki kia mau mai i ngā ariā ara auaha ki te pono mā ngā papa i hangaia mō ō rātou hiahia. Ka whakaaetia e ngā ratonga tā arawhiti mō te whakakā ICB kōrero katoa i runga anō i ngā whakaritenga tāuke a ia kiritaki.
Hei whakarāpopototanga, kei te whiwhi ngā rongoā PCB kōrero i te tikanga kōrero puta noa i te wāhanga ā-hiko o nāianei. Ko ngā kīanga matua pēnei i te Ratonga Tā Arawhiti, PCB Ritenga, Tā PCB Ritenga, PCB Maker, me te Kamupene Hanga PCB e whakamārama ana i ngā wāhiwera me ngā trajectories tupu o te umanga. Mā te whakamahi i ngā pūhāhau PCB e taea ai e ngā kiritaki te haumaru i te kāniwha runga, te ultra-precise, me ngā hua PCB āta whakaritea, te whakaputa i ngā whakahaere hou me ngā whakarewa hua hōu kia whiwhi ai ki tētahi tapa whakataetae. Ahakoa ko ngā taiete, kaihanga rānei, ngā ratonga PCB kua whakaritea mai i te PCB ka taea e ngā kamupene te whakarato i te rongoā tino pai mō ā rātou whakaritenga arawhiti.
