Ukuba ukushicilelo lwebhodi yesekethe (PCB) yokuvelisa ishishini, usenokudibana nombuzo: "Ingakanani i-ounce yobhedu e-1 kwiPCB?" Lo ngumbuzo osebenzayo kuba ubukhulu bobhedu kwi-PCB buneziphumo ezibalulekileyo ekusebenzeni kwayo kwaye Ukusebenza ngokubanzi kudlala indima ebalulekileyo.Kule posi yebhlog, siya kuphonononga kwisihloko kwaye sikunike zonke iinkcukacha eziyimfuneko malunga ne-1 oz ubukhulu bobhedu kwi-PCB.
Phambi kokuba singene kwiinkcukacha, masithathe umva kwaye siqonde ingqikelelo yobunzima bobhedu kwiPCB.Xa sithetha malunga nobunzima bobhedu, sibhekisa kubunzima bomaleko wobhedu osetyenziselwa ukwenza iPCB. Iyunithi yokulinganisa ubunzima bobhedu zii-ounces (oz). Kufuneka kuqatshelwe ukuba ubukhulu bobhedu bulingana nobunzima bawo, oko kukuthi, njengoko ubunzima bukhula, ubukhulu buya kwanda.
Ngoku makhe sigxininise kwi-ounce enye yobhedu. Igama elithi "1 ounce yobhedu" libhekisa kwi-ounce enye kwisikwere sonyawo lobhedu olusetyenziswa kwi-PCB yokwenza.Ukubeka nje, ubukhulu be-1 ounce yobhedu kwi-PCB bumalunga ne-1.37 mils okanye i-intshi ye-0.00137, elingana ne-34.8 microns. Lo mlinganiso ngumgangatho woshishino kwaye usetyenziswa kwiintlobo ngeentlobo zezicelo.
Ubukhulu be-1 ye-ounce yobhedu kwi-PCB ithathwa njengento efanelekileyo kwizicelo ezininzi ezifuna amandla aphakathi kunye nokuhanjiswa komqondiso.Ibetha ibhalansi egqibeleleyo phakathi kokusebenza kunye nokusebenza kakuhle kweendleko. Nangona kunjalo, kufuneka kukhunjulwe ukuba izicelo ezahlukeneyo zinokufuna ubunzima obuhlukeneyo bobhedu. Ngelixa i-1 oz copper iguquguquka, ezinye iinketho ezifana ne-2 oz okanye i-0.5 oz yobhedu zinokulungela ngakumbi iimeko ezithile.
Ngoku sele sixoxe ngobunzima be-ounce enye yobhedu, makhe siphonononge ezinye zezinto eziphambili ezimisela ukhetho lobunzima bobhedu kwiPCB.Okokuqala, kuxhomekeke kwiimfuno zamandla zesekethe. Ukuba isiphaluka sidinga ukuthwala imisinga ephezulu, umaleko otyebileyo wobhedu unokufuneka ukuze uqinisekise ukuhanjiswa okwaneleyo kunye nokuthintela ukuveliswa kobushushu obugqithisileyo. Ngakolunye uhlangothi, izicelo zamandla aphantsi zingasebenzisa iileya zobhedu ezincinci.
Okwesibini, ukuphindaphindwa kweempawu ezithwalwa yiPCB nako kuchaphazela ukhetho lobunzima bobhedu.Iifrikhwensi eziphezulu zifuna umaleko wobhedu ongqindilili ukunciphisa ukulahleka komqondiso kunye nokugcina imfezeko yomqondiso. Oku kubaluleke ngakumbi kwiisekethe zedijithali ezinesantya esiphezulu kunye nosetyenziso lwamaza kanomathotholo.
Ukongeza, amandla omatshini kunye nokuqina kwePCB kuchaphazeleka ubunzima bobhedu.Iingqimba zobhedu ezityebileyo zibonelela ngenkxaso engcono kwaye zinciphisa umngcipheko womonakalo ngexesha lokuphatha, ukudibanisa kunye nokusebenza.
Lilonke, ubukhulu be-1 ounce yobhedu kwi-PCB bumalunga ne-1.37 mils okanye i-intshi ze-0.00137.Ingumlinganiselo oqhelekileyo osetyenziswa ngokubanzi kwishishini kwiintlobo ezahlukeneyo zezicelo. Nangona kunjalo, kubalulekile ukuqwalasela iimfuno ezithile zePCB kunye nohlobo lwesekethe ukumisela ubunzima obufanelekileyo bobhedu. Izinto ezinje ngeemfuno zamandla, ukuphindaphindwa komqondiso, kunye namandla oomatshini bonke bayangena xa usenza esi sigqibo.
Isishwankathelo, ukwazi ubukhulu be-1 ounce yobhedu kwi-PCB kubalulekile kuye nabani na obandakanyekayo kwishishini lemveliso ye-PCB.Inceda ukwenza izigqibo ezinolwazi malunga noyilo kunye nenkqubo yokuvelisa, ukuqinisekisa ukusebenza kakuhle kwesekethe. Ke, kwixesha elizayo xa umntu ekubuza "Ingakanani i-ounce yobhedu e-1 kwiPCB?" unalo lonke ulwazi olufunekayo ukuze ubanike impendulo echanekileyo.
