Ko te parahi tētahi o ngā konganuku tino maha ngā whakamahinga o te ao. Nā ōna āhuatanga ahurei e pai ai mō te whānuitanga o ngā mahi, tae atu ki te kawe hiko. He nui te whakamahinga o te parahi i roto i ngā ahumahi hiko me te hikohiko, ā, he mea nui ngā pepa parahi mō te hanga papa ara iahiko tā (PCB). I roto i ngā momo pepa parahi rerekē e whakamahia ana i roto i te hanga PCB, ko te pepa parahi ED te mea e whakamahia whānuitia ana.
Ka hangaia te pepa parahi ED mā te tukunga hiko (ED), he tukanga e uru ana ki te tukunga o ngā ngota parahi ki runga i te mata whakarewa mā te iahiko hiko. He tino parakore, he ōrite, ā, he tino pai ngā āhuatanga ā-pūkaha me te hiko o te pepa parahi ka puta.
Ko tētahi o ngā painga matua o te pepa parahi ED ko tōna ōritetanga. Mā te tukanga whakatakotoranga hiko ka whakarite kia ōrite te matotoru o te pepa parahi puta noa i tōna mata katoa, he mea nui tēnei i roto i te hanga PCB. Ko te matotoru o te pepa parahi ka tohua i roto i ngā maikorona, ā, ka taea te horapa mai i te torutoru maikorona ki te maha tekau maikorona, i runga i te whakamahinga. Ko te matotoru o te pepa parahi ka whakatau i tōna kawe hiko, ā, ko te pepa matotoru he nui ake te kawe hiko.
Haunga tōna āhua ōrite, he tino pai ngā āhuatanga ā-pūkaha o te pepa parahi ED. He tino ngāwari, ā, ka taea te piko, te hanga, me te hanga kia uru ki ngā āhua o te PCB. Nā tēnei ngāwari, he rauemi pai mō te hanga PCB he uaua ngā āhua me ngā hoahoa. Heoi anō, nā te ngāwari teitei o te pepa parahi ka taea e ia te tu atu ki te piko me te piko tonu me te kore e pakaru, e whati rānei.
Ko tētahi atu āhuatanga nui o te pepa parahi ED ko tōna kawe hiko. Ko te parahi tētahi o ngā konganuku tino kawe hiko, ā, ko te kawe hiko o te pepa parahi ED he neke atu i te 5×10^7 S/m. He mea nui tēnei taumata kawe hiko teitei i roto i te hanga PCB, e āhei ai te tuku tohu hiko i waenga i ngā wāhanga. Heoi anō, ko te iti o te ātete hiko o te pepa parahi ka whakaiti i te ngaronga o te kaha tohu, he mea nui i roto i ngā tono tere-tiketike me te auau-tiketike.
He tino ātete hoki te pepa parahi ED ki te waikura me te waikura. Ka tauhohe te parahi ki te hāora i te rangi hei hanga i tētahi paparanga angiangi o te waikura parahi i runga i tōna mata, ka taea te whakararu i tōna kawe hiko. Heoi, ko te pepa parahi ED he mea pani ki tētahi paparanga o te rauemi tiaki, pērā i te tine, te nikara rānei, hei ārai i te waikura me te whakapai ake i tōna kaha ki te whakapiri.
Hei whakamutunga, he rauemi maha ngā whakamahinga o te pepa parahi ED, ā, he mea nui hoki mō te hanga PCB. Nā tōna ōritetanga, tōna ngāwari, tōna kawe hiko teitei, me tōna ātete ki te waikura me te waikura, he mea pai tēnei hei rauemi mō te hanga PCB me ngā āhua uaua me ngā whakaritenga mahi teitei. I te mea kei te piki haere te hiahia mō ngā hiko tere me te auau teitei, ka piki ake te hiranga o te pepa parahi ED i ngā tau e haere ake nei.
