Sab pem hauv ntej thiab sab nraub qaum ntawm PCB Circuit Court yog qhov tseem tooj liab txheej. Hauv kev tsim cov pcb circuits, tsis muaj teeb meem txawm tias tus nqi tooj liab tau xaiv los ua cov lej sib ntxiv thiab rho tawm, qhov kawg yog qhov chaw zoo thiab dawb huv. Txawm hais tias lub cev cov khoom ntawm tooj liab tsis muaj kev zoo siab li txhuas, hlau, tooj hlau thiab lwm yam tooj liab thiab oxygen yog qhov ua rau oxidation heev; Xav txog lub neej ntawm CO2 thiab dej nyob hauv huab cua, qhov chaw ntawm txhua tus tooj liab tom qab sib cuag nrog roj, ib qho redox tshuaj yuav tshwm sim sai. Xav tias qhov tuab ntawm lub tooj liab txheej hauv PCB Circuit Coast dhau heev, lub xeev oxidation yuav dhau los ua cov khoom siv hluav taws xob, uas yuav ua rau cov khoom siv hluav taws xob ntawm txhua lub pcb circuits.

Txhawm rau kom muaj kev tiv thaiv oxidation zoo dua, thiab kom zoo dua qub ntawm PCB Circuit Cotic, thiab txhawm rau txhim kho vuam, thiab txhawm rau siv cov khoom siv hluav taws xob pcb Cov txheej txheem kos duab ntxiv tuaj yeem yooj yim txhuam ntawm cov PCB Circuit Court, ua rau cov txheej txheem tiv thaiv uas yuav tsum muaj nyias thiab thaiv ntawm tooj liab thiab roj. Cov txheej no yog hu ua tooj liab, thiab cov khoom siv raw yog daim npog ntsej muag
