Ngā Painga o ngā Pereti Tirotiro Granite mō te Whakapūmau Kounga PCB.

 

I te ao o te hanga hikohiko, inā koa i roto i te hanga o ngā papa hikohiko tānga (PCB), he mea tino nui te whakapūmau kounga. Ko tētahi o ngā taputapu tino whai hua hei whakarite i te tika me te tika o te hanga PCB ko te whakamahinga o ngā papa tirotiro karāhe. He maha ngā painga o ēnei mata pakari, pumau hoki e whakarei ake ana i te tukanga whakapūmau kounga.

Tuatahi, he tino papatahi, he pakari hoki ngā pereti tirotiro karāneti. Nā ngā āhuatanga tūturu o te karāneti, ehara i te mea he papatahi noa te mata, engari he iti ake hoki te tūponotanga o te piko me te whakarerekē i te āhua i roto i te wā. He mea nui tēnei pumau i te wā e ine ana i ngā PCB, nā te mea ahakoa he iti noa ngā hapa ka arahi pea ki ngā hapa nui i roto i te tukanga hanga. Mā te whakamahi i ngā pereti karāneti, ka taea e ngā kaihanga te whakarite kia tika ā rātou inenga, ka hua ake he hua kounga teitei ake.

Hei tāpiritanga, he tino pakari, he ātete hoki ki te kakahu ngā papa tirotiro karāhe. Kāore i rite ki ētahi atu rauemi ka memeha, ka pakaru rānei i roto i te wā, ka mau tonu te kounga o te karāhe, ka whakarato i tētahi otinga pumau mō te whakapūmau kounga. Ko te tikanga o tēnei pakari he iti ake ngā utu tiaki me te iti ake o te whakakapinga, ka waiho ngā papa karāhe hei whiringa utu iti mā ngā kaihanga PCB.

Ko tētahi atu painga nui o ngā pereti tirotiro karāhe ko tōna hototahi ki te whānuitanga o ngā taputapu ine. Ahakoa he calipers, he micrometers, he mīhini ine taunga rānei (CMMs), ka taea e ngā pereti karāhe te whakauru i ngā momo taputapu, ā, he pai mō ngā tono whakapūmau kounga rerekē. Mā tēnei urutau ka taea e ngā kaihanga te whakahaere i ā rātou tukanga tirotiro me te whakapai ake i te whai huatanga whānui.

Hei whakamutunga, he mārama ngā painga o ngā papa tirotiro karāhe hei whakapūmau i te kounga o te PCB. Nā te papatahi pai, te pakari, me te hototahi ki ngā taputapu ine, he taonga nui ēnei mō te umanga hanga hikohiko. Mā te haumi ki ngā papa tirotiro karāhe, ka taea e ngā kaihanga te whakapai ake i ā rātou tukanga whakapūmau kounga, ā, ka puta he hua PCB kounga teitei, ka whakapai ake hoki i te pai o te kiritaki.
