Pepa parahi mō te PCB

Nā te pikinga ake o te whakamahinga o ngā taputapu hiko, kua piki tonu te hiahia mō ēnei taputapu i te mākete. Kei te karapotia tātou e ēnei taputapu i ēnei rā, nā te mea he nui tō tātou whakawhirinaki ki a rātou mō ngā kaupapa rerekē. Nā reira, ki taku whakaaro kua tūtaki koe ki tētahi taputapu hiko, kua whakamahia rānei e koe i te kāinga. Ki te whakamahi koe i ēnei taputapu, tera pea koe e whakaaro me pēhea te waea o ngā wāhanga o te taputapu hiko, me pēhea te mahi, me pēhea hoki te hono atu i te taputapu ki ētahi atu mea. Ko ngā taputapu hiko e whakamahia ana e tātou i te kāinga he mea hanga ki ngā rauemi kāore e kawe hiko. He ara kua whakairohia ki te parahi kawe hiko i runga i ō rātou mata, e tuku ana i te tohu kia rere i roto i te taputapu i te wā e whakahaerehia ana.

Nō reira, ko te hangarau o te PCB e ahu mai ana i te mārama ki te mahi a ngā taputapu hiko. He mea nui te whakamahi i te PCB i roto i ngā taputapu hiko i hangaia mō ngā pāpāho. Heoi, i tēnei whakatupuranga hou, kua whakauruhia ki roto i ngā taputapu hiko katoa. Nā reira, kāore e taea e tētahi taputapu hiko te mahi me te kore he PCB. E arotahi ana tēnei tuhinga ki te pepa parahi mō te PCB, me te mahi a tepepa parahii roto i te umanga papa hiko.

Te Hangarau o te Papa Ara Iahiko Tānga (PCB)

Ko ngā PCB ngā ara e kawe ana i te hiko pērā i ngā tohu me ngā ara, kua whakakikoruatia ki te pepa parahi. Mā tēnei ka hono atu, ka tautoko hoki i ētahi atu wāhanga hiko e honoa ā-mīhini ana ki te taputapu. Nā reira, ko te mahi matua o ēnei PCB i roto i ngā taputapu hiko ko te tautoko i ngā ara. I te nuinga o te wā, ka taea e ngā rauemi pērā i te muka karāhe me ngā kirihou te pupuri ngāwari i te pepa parahi i roto i te ara iahiko. Ko te pepa parahi i roto i te PCB he mea whakakikorua ki te papa kore-kawe. I roto i te PCB, he mahi nui tā te pepa parahi ki te tuku i te rere o te hiko i waenga i ngā wāhanga rerekē o te taputapu, kia tautokona ai te whakawhitiwhiti kōrero.

Kei te hono tonu ngā hōia i te mata PCB me ngā taputapu hiko. He mea hanga ēnei tūhono ki te konganuku e hanga ana hei piripiri kaha; nō reira, he pono ki te tautoko i ngā wāhanga. Ko te ara PCB he mea whakaranu ki ngā paparanga maha o ngā rauemi rerekē pērā i te hiraka me ngā konganuku kua whakakikoruatia ki te papa hei hanga PCB.

Te tūranga o te pepa parahi i roto i te umanga papa hiko

Ko te hangarau hou e ahu mai ana i ēnei rā, ko te tikanga kāore he taputapu hiko e mahi me te kore he PCB. I tētahi atu taha, he nui ake te whakawhirinaki o te PCB ki te parahi i ngā wāhanga kē atu. Nā te mea ka āwhina te parahi ki te hanga tohu e hono ana i ngā wāhanga katoa o te PCB kia rere ai te utu i roto i te taputapu. Ka taea te whakaahua i ngā tohu hei ngā uaua toto i roto i te anga o te PCB. Nō reira, kāore e taea e te PCB te mahi ina ngaro ngā tohu. Ina kore te PCB e mahi, ka ngaro te ariā o te taputapu hiko, ā, ka kore e whai hua. Nō reira, ko te parahi te wāhanga kawe hiko matua o te PCB. Mā te pepa parahi i roto i te PCB ka whakarite kia rere tonu ngā tohu me te kore e motuhia.

E mōhiotia ana he nui ake te kawe hiko o te rauemi parahi i ērā atu rauemi nā te mea he kore utu ngā irahiko kei roto i tōna anga. Ka taea e ngā irahiko te neke noa me te kore e ātete ki tētahi ngota e āhei ai te parahi ki te kawe i ngā utu hiko neke me te kore e ngaro, e whakararuraru rānei i ngā tohu. Ko te parahi, e hanga ana i tētahi irahiko kino tino pai, ka whakamahia tonutia i roto i ngā PCB hei paparanga tuatahi. Nā te mea he iti ake te pānga o te hāora o te mata ki te parahi, ka taea te whakamahi e ngā momo paparanga maha, ngā paparanga ārai, me ngā konganuku. Ina whakamahia me ēnei paparanga, ka hangaia he tauira rerekē i roto i te ara iahiko, inā koa i muri i te whakairo. Ka taea tonu tēnei nā te kaha o te parahi ki te hanga hononga tino pai ki ngā paparanga ārai e whakamahia ana hei hanga i te PCB.

E ono ngā paparanga o te PCB e hangaia ana, ā, e whā ngā paparanga kei roto i te PCB. Ko ngā paparanga e rua e tāpirihia ana ki te panera o roto. Nā reira, ko ngā paparanga e rua mō te whakamahinga o roto, e rua anō mō ​​te whakamahinga o waho, ā, ko ngā paparanga e rua e toe ana i roto i ngā paparanga e ono katoa hei whakapaipai i ngā panera o roto i te PCB.

Whakamutunga

Pepa parahiHe wāhanga nui o te PCB e āhei ai te rere o ngā utu hiko me te kore e mutu. He nui tōna kawe hiko, ā, he tino pai te hononga ki ngā rauemi ārai rerekē e whakamahia ana i roto i te papa ara iahiko PCB. Nā konei, ka whakawhirinaki te PCB ki te pepa parahi hei mahi māna, nā te mea ka whai hua te hononga o te angaanga PCB.
