Kwimveliso yombane, iibhodi zeesekethe eziprintiweyo (PCBs) zidlala indima ebalulekileyo ekuboneleleni ngesiseko esiluqilima samacandelo ahlukeneyo e-elektroniki kunye neesekethe.Njengoko i-PCB yokuvelisa kunye nendibano iqhubeka nokuvela, kubalulekile ukuba abavelisi baqonde ingcamango yepesenti ye-PCB kunye nendlela yokubala ngokuchanekileyo.Le bhlog ijolise ekukhanyiseleni kwesi sihloko kwaye ibonelele ngeembono ekwandiseni isivuno sePCB.
Ukuqonda iipesenti zePCB:
Ipesenti yePCB ibhekisa kumlinganiselo wesivuno senkqubo yemveliso yePCB, ebonisa umyinge wePCBs ezisebenzayo eziveliswe kwinani lilonke leePCB ezenziweyo okanye ezidityanisiweyo.Ukubala ipesenti yePCB kubalulekile kubavelisi njengoko kubonisa ukusebenza kakuhle kunye nomgangatho wenkqubo yokuvelisa.
Ibalwa njani ipesenti yePCB:
Ukubala ipesenti yePCB, kufuneka uqwalasele izinto ezimbini eziphambili: inani leePCB ezisebenzayo kunye nenani lilonke leePCB ezenziweyo okanye ezidityanisiweyo kwimveliso ethile.
1. Qinisekisa inani lee-PCB ezisebenzayo: Oku kubhekiselele kwii-PCB eziphumelele zonke iimvavanyo zokulawula umgangatho kwaye zihlangabezane nemigangatho efunekayo.Masithi uvelise ii-PCB ezili-100, kwaye emva kovavanyo olucokisekileyo, ezingama-90 kuzo zafunyanwa zisebenza ngokupheleleyo.
2. Bala ipesenti yePCB: Yahlula inani leePCB ezisebenzayo ngenani lilonke leePCB ezenziweyo okanye ezidityanisiweyo, emva koko phinda-phinda isiphumo nge-100 ukufumana ipesenti yePCB.
Ipesenti yePCB = (Ubuninzi bePCB eSebenzayo / Ubuninzi bePCB iyonke) * 100
Ukusebenzisa umzekelo wangaphambili, ukubala oku: (90/100) * 100 = 90%
Yandisa iSivuno sePCB:
Ukufikelela kwipesenti ephezulu yePCB ilungele abavelisi bezinto zombane njengoko ichaphazela ngqo inzuzo yabo kunye nokwaneliseka kwabathengi.Nazi ezinye izicwangciso zokwandisa isivuno sePCB:
1. Sebenzisa imilinganiselo eyomeleleyo yolawulo lomgangatho: Qinisekisa ukuba yonke iPCB eveliswayo ivavanywa ngokucokisekileyo ukuze kubonwe naziphi na iziphene okanye iingxaki kwangethuba.Oku kuvumela ukulungiswa ngexesha kwaye kunciphisa inani leePCB ezingalunganga.
2. Ukuphucula inkqubo yakho yokuvelisa: Qhubeka nokuvavanya kwaye uphucule inkqubo yakho yokuvelisa ukunciphisa iimpazamo, ukunciphisa ixesha lokuvelisa, kunye nokuphucula isivuno sonke.Qwalasela utyalo-mali kwi-PCB ephucukileyo yokwenziwa kunye nobuchwepheshe bendibano ukuphucula ukusebenza kakuhle kunye nokuchaneka.
3. Ukuqinisa uqeqesho lwabaqhubi: ukuqhuba uqeqesho olubanzi kunye noluqhelekileyo lwabaqhubi ababandakanyekayo kwinkqubo yokuvelisa i-PCB.Umsebenzisi oqeqeshwe kakuhle akanakwenzeka ukuba enze iimpazamo, okukhokelela kwizinga eliphezulu lokungaphumeleli kwePCB.
4. Ukusetyenziswa kweendlela zoLawulo lweNkqubo yeNkcazo (SPC): Ukusetyenziswa kweendlela ze-SPC kukuvumela ukuba ubeke iliso kwaye ulawule yonke inkalo yemveliso, uqinisekise ukuhambelana kunye nokunciphisa ukuhluka.I-SPC inceda ekuchongeni iingxaki ezinokubakho kwangoko ukuze kuthathwe amanyathelo okulungisa ngaphambi kokuba kwenzeke ilahleko enkulu yesivuno.
ukuququmbela:
Ukubala ipesenti yePCB kubalulekile kubavelisi ukuvavanya ukusebenza kakuhle kwenkqubo yabo yokuvelisa.Ngokuqonda indlela yokubala kunye nokwandisa izivuno zePCB, abavelisi banokunciphisa inkunkuma, banyuse ingeniso, kwaye bahambise iiPCB ezikumgangatho ophezulu kubathengi.Ukuphumeza imilinganiselo eyomeleleyo yokulawula ubulunga, ukukhulisa iinkqubo zokwenziwa kwemveliso, ukomeleza uqeqesho lwabaqhubi, kunye nokwamkela ubuchule be-SPC ngamanyathelo abalulekileyo okuphumeza izivuno eziphezulu zePCB.Ngokuqhubeka nokuphucula le miba, abavelisi bezinto zombane banokuhlala bekhuphisana kwihlabathi eliguqukayo lokwenziwa kwePCB kunye nokuhlanganisa.
