Yahlulela ikhwalithi ye- PCB ibhodi ngombala we-PCB

Okokuqala, i-PCB, njengebhodi lesifunda eliphrintiwe, ikakhulukazi linikeza ukuxhumana phakathi kwezingxenye zikagesi. Umbala awuhlobene ngqo nokusebenza, futhi umehluko wezingulube akuthinti ukusebenza kukagesi. Ukusebenza kwe-PCB kunqunywa ngezinto ezisetshenzisiwe (i-Q ephezulu), ukwenziwa kwentambo, kanye nenani lamabhodi. Kodwa-ke, enqubeni yokuwashwa kwe-PCB, umnyama yikhona okungenzeka kakhulu ukuthi kubangele umehluko wombala. Uma izinto zokusetshenziswa kanye nenqubo yokukhiqiza esetshenziswa yifektri ye-PCB yehluke kancane, izinga lokukhubazeka le-PCB lizokhuphuka ngenxa yomehluko wombala. Lokhu kuholela ngqo ekwandeni kwezindleko zokukhiqiza.

Eqinisweni, izinto zokusetshenziswa ze-PCB zikuyo yonke indawo empilweni yethu yansuku zonke, okuyi-fiber fiber ne-resin. I-fiberglass ihlangana ne-resin futhi iqine ibe yibhodi elifakwa ngogqinsi, elifakiwe futhi elingagobeki kalula. Le yi-substrate ye-PCB. Vele, i-PCB substrate eyenziwe nge-fiber fiber kanye ne-resin iyodwa ayikwazi ukuqhuba isignali, ngakho-ke ku-substrate ye-PCB, umenzi uzomboza ingaphezulu ngendwangu yethusi, ngakho-ke i-PCB substrate nayo ingabizwa ngokuthi i-substrate eboshwe ngethusi.

Ngoba umzila wesifunda we-PCB emnyama kunzima ukuwubona, kuzokwandisa ubunzima bokulungiswa nokulungisa iphutha ku-r & d nangemva kokuthengisa. Ngokuvamile, uma kungekho mkhiqizo onabakhi be-RD (UCWANINGO nentuthuko) nethimba elinamandla lokulungisa elinamakhono ajulile, i-PCB emnyama ngeke isetshenziswe kalula. Kungashiwo ukuthi ukusetshenziswa kwe-PCB emnyama kungukukhonjiswa kokuzethemba komkhiqizo ekwakhiweni kwe-RD nethimba lesondlo sekwephuzile. Ngasohlangothini, kubuye kukhombise ukuzethemba komkhiqizi ngamandla abo.

Ngokuya ngezizathu ezingenhla, abakhiqizi abakhulu bazocubungula ngokucophelela lapho bekhetha ukwakheka kwenguqulo ye-PCB yemikhiqizo yabo. Ngakho-ke, iningi lemikhiqizo enokuthunyelwa okukhulu emakethe ngalowo nyaka kusetshenziswe i-PCB ebomvu, i-PCB eluhlaza noma inguqulo ye-PCB eluhlaza okwesibhakabhaka. I-PCB emnyama ingabonakala kuphela emikhiqizweni esezingeni eliphakathi nendawo ephezulu noma ephezulu, ngakho-ke ungacabangi ukuthi i-PCB emnyama ingcono kune-PCB eluhlaza.
