Kutheni uxubha ipeyinti yokubonisa kwakhona ibhodi yesekethe ye-PCB?

Ipeyinti yokuvavanywa kathathu yingubo eyenziwe ngokukodwa, esetyenziselwa ukukhusela PCB kunye nezixhobo zayo ezinxulumene nokhukuliseko lomhlaba ombi. Iipeyinti ezintathu zokuvavanywa zinokumelana nobushushu obuphezulu kunye nobushushu obuphantsi. Emva kokuphilisa, iyakwenza ifilimu ekhuselayo ebonakalayo ukukhusela isekethe kumonakalo phantsi kweemeko zemichiza, ukufuma, inkungu yetyuwa, ukufuma kunye nobushushu obuphezulu.

Ngaphantsi kwezi meko, ibhodi yesekethe inokuthi idleke, ukukhula kwesikhunta kunye nokujikeleza okufutshane. Ipeyinti ezintathu ezichaseneyo zineempawu ezigqwesileyo ezifana nokugquma, ubungqina bomswakama, ukuvuza okungafunekiyo, ubungqina obunothuli, anti-corrosion, anti-ukwaluphala, ukungunda okuchaseneyo, ukukhululeka kwenxalenye yokuqhaqha kunye nokumelana ne-corona ukumelana. Phakathi kwazo, ukufuma yeyona nto ixhaphakileyo neyonakalisayo kwi-PCB. Ubumanzi obuninzi buya kunciphisa kakhulu ukumelana nokugquma phakathi kwabaqhubi, ukukhawulezisa ukubola kwesantya esiphezulu, ukunciphisa ixabiso le-Q kunye neekhowudi ezihamba phambili. Sisoloko sibona ukuba icandelo lesinyithi le PCB Ibhodi iluhlaza, ebangelwa kukusabela kweekhemikhali ngobhedu, umphunga wamanzi kunye neoksijini, engafakwanga iipeyinti ezintathu zokufunda kwakhona.

Xa iipeyinti ezintathu zokufunda zigqityiwe kwibhodi yesekethe yePCB nakumacandelo, xa inokuchaphazeleka zizinto ezigwenxa kwimeko yokusebenza, ukonakala kokusebenza kombane kunokuncitshiswa okanye kupheliswe. Ukuba ukutyabeka kunokugcina ukusebenza kwayo kangangexesha elonelisayo, njengokude kubomi benkonzo yemveliso, kunokuthathwa njengokufezekisa injongo yayo yokutyabeka
