I te ao hikohiko, ko ngā papa hikohiko tā (PCB) te pou tuara o te nuinga o ngā taputapu e whakamahia ana e tātou i ēnei rā. Mai i ngā waea atamai ki ngā taputapu kāinga, he mea nui ngā PCB hei hono i te whānuitanga o ngā wāhanga hiko. Ko tētahi o ngā āhuatanga tino nui o te hanga PCB ko te tukanga keri, koinei te wāhi engā moka wiri papa ara iahiko tāngakia whai hua ai. I roto i tēnei tuhinga, ka tūhuratia e mātou ngā momo mata wiri e whakamahia ana mō ngā PCB, ō rātou whakaritenga, me ngā tohutohu mō te whiriwhiri i te taputapu tika mō tō kaupapa.
Te Mārama ki ngā Momo Wiri PCB
He taputapu motuhake ngā mata wiri papa ara iahiko tānga hei keri i ngā kōhao i roto i ngā PCB hei whakanoho i ngā wāhanga me te hanga hononga hiko. He maha ngā rahi me ngā rauemi o ēnei mata wiri, ia mea he mea hanga mō tētahi tono motuhake. Ko te tika me te kounga o te mata wiri ka pā tika ki te mahi whānui me te pono o te PCB.
Ngā Momo Mata Wiri PCB
1. Mīhini Wiri Hurihuri:Koinei te momo mata wiri e whakamahia whānuitia ana mō ngā PCB. He hoahoa porowhita tō rātou hei āwhina i te tango i ngā paru i te wā e keri ana. He maha ngā diameter o ngā mata wiri miro mō ngā kōhao rerekē te rahi.
2. Ngā Mīhini Wiri Iti:He mea nui ngā mata keri moroiti mō ngā mahi e hiahia ana ki ngā kōhao tino iti. Ka taea e ēnei mata keri te keri i ngā kōhao tae noa ki te 0.1 mm te iti, he mea tino pai mō ngā PCB kiato nui ina he iti te wāhi.
3. Ngā Mata Wiri Warowaihā:He mea hanga ēnei mata wiri ki te tungsten carbide, e mōhiotia ana mō tō rātou pakari me te kaha ki te pupuri i te koi mō te wā roa. He tino whai hua ēnei mō te keri i roto i ngā rauemi mārō, ā, he mea rongonui mō ngā PCB maha-paparanga.
4. Ngā Mīti Wiri Kua Pania ki te Taimana:Mō te tino tika me te roa o te wā, ko ngā mata wiri kua pania ki te taimana te paerewa koura. Ka whakaitihia e te paninga taimana te waku me te wera kia ma ake ai ngā tapahi, kia roa ake ai te ora o te taputapu. He maha ngā wā ka whakamahia ēnei mata wiri i roto i ngā tono teitei e tino hiahiatia ana te tika.
Ngā whakaritenga matua hei whakaaroaro
I te wā e whiriwhiri ana koe i tētahi mata wiri mō ngā papa hiko tā, he maha ngā āhuatanga hei whakaaroaro māu:
- Te whānui:He mea nui te rahi o te mata wiri kia tutuki ai te kōhao i ngā whakaritenga hoahoa o te PCB. Ko ngā diameter noa kei waenga i te 0.2mm ki te 3.2mm.
- Roa:Me rite te roa o te mata wiri ki te matotoru o te PCB. Tērā pea ka hiahiatia he mata wiri roa ake mō ngā papa maha-paparanga.
- Ngā Koki Koi:Ka pāngia te pai o te tapahi me te kounga o te kōhao e ngā koki koi. Ko ngā koki koi paerewa he 118 nekehanga te nuinga, engari ka taea te whakamahi i ngā koki motuhake mō ngā mahi motuhake.
- Rauemi:Ka pā te rauemi o te mata wiri ki tōna mahi me tōna roanga o te ora. He pai ake ngā mata wiri kua pania ki te karapīti me te taimana nā te mea he roa.
Ngā tohutohu mō te whiriwhiri i te mata wiri tika
1. Arotakehia ngā whakaritenga o tō kaupapa:I mua i te hoko i tētahi mata wiri, arotakehia ngā āhuatanga o tō hoahoa PCB. Whakaarohia te rahi o te kōhao, te maha o ngā paparanga, me ngā rauemi e whakamahia ana.
2. Kounga i runga ake i te utu:Ahakoa he mea whakamātau pea te whiriwhiri i tētahi mata wiri iti te utu, mā te haumi ki tētahi mata wiri kounga teitei ka taea e koe te penapena i tō wā me tō moni mō te wā roa. Ka whakaitihia e ngā mata wiri kounga teitei te mōrearea o te pakaru, ā, ka whakarite kia ma ake te kōhao.
3. Whakamātauria ngā momo rerekē:Ki te kore koe e tino mōhio ko tēhea te mata wiri e pai ana mō tō kaupapa, whakaarohia te whakamātautau i ētahi momo mata wiri rerekē. Mā tēnei koe e āwhina ki te whakatau ko tēhea te mata wiri e pai ana mō tō tono.
4. Tiakina āu taputapu:He mea nui te tiaki tika i ō mata wiri kia roa ake ai te ora. Horoia, tirohia hoki ngā mata wiri i ia wā, i ia wā, mō te pakaru, ā, whakakapia ngā mata ina hiahiatia kia mau tonu ai te mahi pai.
Hei whakamutunga
He wāhanga nui ngā mata wiri o te papa hiko tānga mō te hanga PCB, ā, he mea nui hoki ki te whakarite i te tika me te pono. Mā te mārama ki ngā momo mata wiri rerekē e wātea ana, me te whakaaro ki ngā whakaritenga matua, ka taea e koe te whakatau whai whakaaro hei whakapai ake i te kounga o ō kaupapa hiko. Ahakoa he tangata whakangahau koe, he miihini ngaio rānei, ko te haumi ki ngā taputapu tika ka hua ake he hua pai ake me te rere o te mahi.
