![Te nui o ngā hoko ā-tau mō ngā mīhini whakamatao wai ahumahi a Teyu]()
Tata ki ia wāhanga o te Papa Ara Iahiko Tā (PCB) he tikanga tohu kei roto. Nā te mea ka taea e ngā mōhiohio kua tāia ki te PCB te whakatutuki i te mahi o te aroturuki kounga, te tautuhi aunoa me te whakatairanga waitohu. I mua, i tāia ēnei mōhiohio e ngā mīhini tā tuku iho. Engari he maha ngā mea e pau ana i ngā mīhini tā tuku iho, ā, ka taea te whakararu i te tangata. Ā, ka memeha haere ngā mōhiohio e tāia ana e rātou i te roanga o te wā, kāore i te tino whai hua.
Engari mō te mīhini tohu taiaho, kāore aua raruraru e raru i ēnei rā. Kei te mīhini tohu taiaho te tukatuka kore-pa, te tere tere, kāore he mea pau, ā, kāore he parahanga. Ka taea e ia te mahi tohu tino mārama, tika, ā, roa te mau ki runga i te whakatakotoranga tino iti tae atu ki te 3x3mm. Haunga, nā te mea kāore he pa tika, kāore e kino ki te PCB.
Ko ngā mīhini tohu taiaho PCB noa e whakamahia ana e te taiaho CO2 me te taiaho UV. I raro i ngā whirihoranga ōrite, he nui ake te tika o te mīhini tohu taiaho UV i te mīhini tohu taiaho CO2. Ko te roanga ngaru o te taiaho UV he tata ki te 355nm, ā, he pai ake te mimiti o te nuinga o ngā rauemi i te mārama taiaho UV i te mārama infrared. Hei tāpiri, he momo tukatuka wera te taiaho CO2 hei whakatutuki i te pānga tohu. Nō reira, he ngāwari te waro, he kino ki ngā rauemi turanga o te PCB. Engari, he "tukatuka makariri" te taiaho UV, nā te mea ka tutuki te pānga tohu mā te wawahi i te hononga matū mā te mārama taiaho UV. Nō reira, kāore te taiaho UV e kino ki te PCB.
E mōhio ana tātou, he iti te rahi o te PCB, ā, he uaua te whakamahi i ngā mōhiohio tohu i runga. Engari ka taea e te reihi UV te mahi i tēnei i roto i te huarahi tika. Ehara i te mea nā te āhuatanga ahurei o te mīhini tohu reihi UV anake tēnei engari nā te pūnaha whakamatao hoki e haere tahi mai ana. He mea nui te pūnaha whakamatao tika hei pupuri i te pāmahana o te reihi UV kia pai ai te mahi a te reihi UV i roto i te wā roa. Ko te waeine whakamatao kiato S&A Teyu CWUL-05 e whakamahia whānuitia ana mō te whakamatao i te mīhini tohu reihi UV i roto i te tohu PCB. He 0.2℃ te pumau o te pāmahana o tēnei pouaka whakamatao, ko te tikanga he iti noa te piki me te heke o te pāmahana. Ā, ko te tikanga he iti te piki me te heke ka pumau te putanga reihi o te reihi UV. Nō reira, ka taea te whakamana i te pānga tohu. Hei tāpiri, he iti rawa te rahi o te waeine whakamatao wai kiato CWUL-05, nō reira kāore e nui te wāhi e pau ana, ā, ka taea te uru ngāwari ki te tahora mīhini o te mīhini tohu reihi PCB.
