PCB abaguquli banokubhekisa kwiinguqu ezikwibhodi yesekethe eprintiweyo okanye iinguqu eziqulethe iibiphenyls ezine-polychlorinated. Ngokuqhelekileyo sisixhobo esivulekileyo esivulekileyo, esibekwe phezu kwebhodi yesekethe, kwaye sibonelela ngombane okanye uguquko lwangoku olunokufuneka. Ezi zixhobo ziza kuluhlu olubanzi lweepropathi kunye nobukhulu, ziqinisekisa ukuba iintlobo ziyafumaneka kuyo yonke imveliso onokuyicinga. Kukwakho nezinto ezingabizi kakhulu ezenza iibhodi zesekethe eziprintiweyo zibe noqoqosho ngakumbi ukuvelisa izinto zombane.

Kukwakhona nesiguquli sePCB esingenasiseko. Oku kwenze abaguquli bancinci kakhulu, nangona ezi zixhobo zisalinga kakhulu. Kodwa uluhlu lwezicelo luselukhulu.

Yintoni intsingiselo yesiguquli sePCB

Yintoni intsingiselo yesiguquli sePCB

Iii. Amandla alinganisiweyo esiguquli sePCB

Amandla alinganisiweyo esiguquli sisixa samandla isixhobo esinokuphatha ngaphandle komthwalo. Kwiziguquli zamandla eziphakamileyo kakhulu, ubushushu buyagcinwa ukuya kumanqanaba amkelekileyo kusetyenziswa izinto ezipholisayo ezinjengamanzi kunye nokuhamba komoya okucinezelweyo. Kwi-PCB, amanqanaba awaphakamanga njengakwisiguquli samandla esiphakamileyo, kodwa la manqanaba ashushu angabaluleka kakhulu ekubeni isixhobo siyakwazi ukusebenza kwi-PCB.

Iv. Indlela yokufaka i-PCB

Zimbini iindlela eziphambili zokuxhobisa abaguquli kwiibhodi zesekethe eziprintiweyo: ukunyusa umphezulu kunye nokufaka umngxunya. Kuyenzeka ukuba u-etch sombane sombane ngqo kwibhodi yesekethe eprintiweyo, kodwa oku ngokucacileyo akufuneki kufakelo.

Ne:

Isiguquli sePCB esifakwe kumphezulu asingeni kwizikhonkwane okanye ezinye izinto zebhodi yesekethe eprintiweyo. Oku kuvula ukubakho koyilo oluninzi ngakumbi.

Kule minyaka, iindibano zomhlaba ziye zaba ngamalungu aqhelekileyo eebhodi zesekethe eziprintiweyo. Le ndlela ihlala ikhethwa ukunyusa izinto ezahlukeneyo zombane kwiibhodi zesekethe eziprintiweyo kuba iququzelela uyilo olumbumbulu. Akusoloko kunjalo, kwaye ukususwa kwayo nayiphi na ikhompyuter okanye esinye isixhobo se-elektroniki kunokwenzeka ukuba kubonise ukuba uninzi lwezinto zecebo zibekwe kumgangatho webhodi yesekethe kwaye ngaphandle kwamacingo okanye ezinye izinto zidlulile.

Ngokufaka umngxuma:

Iitshintshi ezifakwe kwimingxunya kwibhodi yesekethe eprintiweyo zixhotyiswe ngezihlanganisi ezingena ebhodini. Oku kwenza ukuba kube lula ukusebenzisa iibhodi zesekethe eziprintiweyo kunye nolunye usetyenziso. Ngokubanzi, indlela yokufaka-emngxunyeni yindlela encinci kunye nexesha elidlulileyo lokunyusa izinto kwibhodi yesekethe eprintiweyo kunokuzibeka ngqo kumphezulu. Kwezinye iinkqubo kunye nezinto ezithile, iseyindlela efanelekileyo yokufaka kwiibhodi zesekethe eziprintiweyo. Nangona kunjalo, uyakufumanisa ukuba uninzi lwezixhobo zenguqu kwibhodi yesekethe eprintiweyo zivuliwe. Kwizixhobo ezindala, i-PCB enenani elikhulu lezinto ezixhonyiweyo emngxunyeni zinokubonwa xa kususwa disassembly.

Yintoni intsingiselo yesiguquli sePCB

Ezintlanu, ubuninzi kunye nobuninzi besantya sokusebenza se-PCB sombane

Elona qondo liphezulu lokusebenza kwesiguquli se-PCB-esihlala silinganiswe kwi-Hertz-sichaza ubuninzi bexesha apho isiguquli sinokusebenza ngokukhuselekileyo kwaye sifumane iiparameter zemveliso ezifunwayo.

Ubuncinane besantya sokusebenza esincanyathiselwe kwi-PCB sombane. Ukusebenza kwesiguquli kumaza asezantsi kunokubangela iziphumo ezingalindelekanga kwaye kunokubangela owona monakalo kumacandelo.

Ubuncinci kunye nobushushu obuphezulu besiguquli sePCB

Icandelo ngalinye le-elektroniki linobushushu obusebenzayo obuncinci. Kwiiguquli zePCB, eli xabiso linokuba kufanelekile kuba isiguquli esifakelwe kwizixhobo zorhwebo okanye esinye isixhobo sinokusebenza kufutshane okanye ngaphantsi kobushushu obusezantsi. Ngaphantsi kobushushu obusezantsi bokusebenza, ukusebenza kwesiguquli akunakuqinisekiswa.

Zonke iiguquli zivelisa ubushushu obuthile, kunye nobushushu obuphezulu besiguquli sePCB banciphisa iimeko ezishushu kakhulu ezinokuthi zisebenze isiguquli. Ukugqithisa eli xabiso kunokubangela ukusilela, ukonakala kwesekethe kunye nezinye iingxaki. Ngenxa yokuba isiguquli sePCB asinakho ukupholisa ulwelo okanye ezinye iindlela zokupholisa ezinobunkunkqele, iinjineli kufuneka zigcine kubushushu obuphezulu bokusebenza.

Isixhenxe, isicelo sombane sePCB

Isiguquli sePCB sisetyenziswa kwizicelo ezahlukeneyo. Kwizixhobo zekhompyuter, abaguquli ngokuthe ngcembe banciphisa amandla ombane ukuya kwinqanaba elikhuselekileyo, elibenza babaluleke. Ikwasetyenziswa kwiinkqubo ezahlukeneyo zemveliso, kunye nezinye izixhobo zabathengi ezifuna abaguquli. Iiguquli zePCB zinokugcina ngokwenene imali eninzi kunye nendawo eninzi kuyilo ngokuthelekiswa nokusebenzisa iinguqu ezinkulu.
