Menene rashin amfanin PCB mai tsauri?Bincike mai zurfi

Buga allo (PCBs) wani sashe ne na fasaha na zamani.Aikace-aikacen su sun bambanta daga wayoyin hannu da kwamfutoci zuwa na'urorin likitanci da tsarin kera motoci.Akwai nau'ikan PCB daban-daban, ɗaya daga cikinsu shine PCB mai tsauri.Yayin da PCBs masu tsattsauran ra'ayi suna ba da fa'idodi da yawa, suma suna da rashin amfanin su.A cikin wannan shafin yanar gizon, za mu bincika rashin amfanin PCBs masu tsauri kuma mu shiga cikin dalilan da ke bayan su.

1. Iyakantaccen sassauci:

Babban rashin lahani na PCBs masu tsauri shine iyakancewar sassauci.Kamar yadda sunan ke nunawa, PCBs masu tsauri ba su da sassauci kuma ba za su iya tanƙwara ko tanƙwara ba.A wasu aikace-aikace, wannan rashin sassauci na iya zama babban koma baya.Misali, a cikin fasahar sawa ko na'urori masu buƙatar motsi akai-akai, PCBs masu tsauri na iya iyakance ƙira da ayyuka gaba ɗaya.Wannan ƙayyadaddun na iya hana haɓaka sabbin na'urorin lantarki da ƙarami.

2. Kalubalen adana sarari:

PCBs masu tsattsauran ra'ayi ba su kai matsayin ceton sarari kamar sauran nau'ikan PCBs.Tun da ba za a iya lanƙwasa su ko siffa ba, suna buƙatar ƙarin sarari, a ƙarshe yana shafar tsarin gaba ɗaya da ƙirar samfuran lantarki.Wannan iyakancewa yana da mahimmanci musamman a cikin ƙananan na'urori ko na'urori masu haɗaɗɗun da'irori, inda kowane milimita na sarari ya ƙidaya.Sau da yawa masu zanen kaya dole ne suyi aiki a kusa da waɗannan iyakoki, yana haifar da sasantawa a cikin ayyukan gaba ɗaya ko haɓaka girman samfurin ƙarshe.

3. Hadaddun wayoyi da haɗuwa:
