Isizathu esiqondile sokukhuphuka kwezinga lokushisa kwe-PCB kungenxa yokuba khona kwemishini yokuhlakaza amandla esekethe, amadivaysi e-elekthronikhi anamazinga ahlukene okuchithwa kwamandla, futhi amandla okushisa ahluka ngokuchithwa kwamandla.
Izimo ezi-2 zokukhuphuka kwezinga lokushisa ku-PCB:
(1) ukukhuphuka kwezinga lokushisa lendawo noma ukukhuphuka kwezinga lokushisa endaweni enkulu;
(2) ukukhuphuka kwezinga lokushisa kwesikhathi esifushane noma eside.
Ekuhlaziyweni kwamandla ashisayo e-PCB, izici ezilandelayo ngokuvamile ziyahlaziywa:
1. Ukusetshenziswa kwamandla kagesi
(1) hlaziya ukusetshenziswa kwamandla endaweni yeyunithi ngayinye;
(2) hlaziya ukusatshalaliswa kwamandla ku-PCB.
2. Isakhiwo se-PCB
(1) ubukhulu be-PCB;
(2) izinto zokwakha.
3. Ukufakwa kwe-PCB
(1) indlela yokufaka (njengokufakwa okuqondile nokufakwa okuvundlile);
(2) isimo sokuvala kanye nebanga ukusuka endlini.
4. Emisebeni eshisayo
(1) i-radiation coefficient yendawo ye-PCB;
(2) umehluko wezinga lokushisa phakathi kwe-PCB nendawo eseduze nezinga layo lokushisa eliphelele;
5. Ukushisa kokushisa
(1) faka irediyetha;
(2) ukwenziwa kwezinye izakhiwo zokufaka.
6. I-convection eshisayo
(1) ukuhamba kwemvelo;
(2) ukupholisa ukupholisa ngempoqo.
Ukuhlaziywa kwe-PCB kwalezi zici ezingenhla kuyindlela ephumelelayo yokuxazulula ukukhuphuka kwezinga lokushisa kwe-PCB, ngokuvamile kumkhiqizo kanye nesistimu lezi zici zihlobene futhi zincike, izici eziningi kufanele zihlaziywe ngokuvumelana nesimo sangempela, kuphela isimo sangempela esithile singaba ngaphezulu. kubalwe kahle noma ukukhuphuka kwezinga lokushisa kanye nemingcele yamandla.
