Njengamandla abalulekileyo ekukhuthazeni ukukhula koqoqosho, ishishini le-elektroniki liphuhliswe ngesantya esitsala amehlo. Nangona kunjalo, njengoko ulwazi lwabantu malunga nokukhuselwa kwendalo luqhubeka lukhula, ukuveliswa kweebhodi zeesekethe eziprintiweyo (PCBs), ikhonkco eliphambili kwishishini le-elektroniki, lijongene nemingeni. Iimfuno eziphezulu zokusingqongileyo. Abavelisi bePCB abanobuhlobo ngokusingqongileyo ngokuthe ngcembe baba ziinkokeli zeshishini kwaye benza igalelo elibalulekileyo kuphuhliso oluzinzileyo loshishino lwe-elektroniki.
一、Ukubaluleka kweePCB ezingenalo ilothe
IiPCB zesiNtu ezinelothe ziya kukhupha izinto eziyingozi ezifana nelothe ngexesha lemveliso nokusetyenziswa, nto leyo ebeka izoyikiso ezinzulu kubume bendalo nakwimpilo yabantu. Ilothe inokungena kwi-ecosystem ngokusebenzisa iatmosfera, amanzi nomhlaba, iqokelelane kwizinto eziphilayo, kwaye ichaphazele ukulungelelana kwe-ikholoji. Kwangaxeshanye, ukuvezwa kwexesha elide kwizinto ezinelothe kunokubangela izifo kwinkqubo yemithambo-luvo yomntu, inkqubo yegazi kunye neminye imiba. Ke ngoko, ukukhuthaza i-PCB engenalo i-lead-free ibe lukhetho olungenakuthintelwa kushishino lwe-elektroniki ukuphumeza uphuhliso oluluhlaza.
二、 Izinto eziluncedo zokusingqongileyo abavelisi bePCB abakhokelayo
Ukuveliswa kweteknoloji
Abavelisi be-PCB abanobuhlobo ngokusingqongileyo bazibophelele kubuchwephesha obutsha kwaye bahlala bephuhlisa iinkqubo ezintsha zemveliso kunye nezixhobo zokuqinisekisa umgangatho wemveliso kunye nokusebenza. Ngokusebenzisa ubuchwephesha bokuthengisa obuphambili obungahoyi ilothe, izinto ezikhusela imekobume, kunye neenkqubo ezingqongqo zokulawula umgangatho, aba bavelisi bayakwazi ukuvelisa iiPCB ezikumgangatho ophezulu ezifikelela imigangatho yokusingqongileyo yamazwe ngamazwe.
Ukuqonda ngokusingqongileyo
Njengabathetheleli bokhuseleko lwendalo esingqongileyo, abavelisi bePCB abangenalo lead badibanisa iingqikelelo zokukhuselwa kwendalo kuyo yonke inkqubo yemveliso. Ukususela ekukhethweni kwezinto eziluhlaza ukuya ekuphuculweni kweenkqubo zokuvelisa ukulahla inkunkuma, iimfuno zokukhusela indalo zilandelwa ngokungqongqo. Bakhuthaza ngenkuthalo iindlela zokuvelisa uhlaza, ukunciphisa ukusetyenziswa kwamandla kunye nokukhutshwa kwezinto ezingcolileyo, kunye negalelo ekukhuselweni kwendalo.
Ukuqinisekisa umgangatho
Abavelisi bePCB abanobuhlobo bokusingqongileyo bakholisa ukuba neenkqubo zolawulo olungqongqo lomgangatho ukuqinisekisa umgangatho ozinzileyo nothembekileyo wemveliso. Basebenzisa izixhobo zovavanyo oluphezulu kunye nabasebenzi bokuhlola umgangatho abaqeqeshiweyo ukwenza uvavanyo olungqongqo kwiPCB nganye ukuqinisekisa ukuba iimveliso ziyahlangabezana nemigangatho yamazwe ngamazwe kunye neemfuno zabathengi.
Iinzuzo zenkonzo
Ukuze kuhlangatyezwane neemfuno zabathengi, abavelisi be-PCB abangenalo i-lead-free badla ngokubonelela ngoluhlu olupheleleyo lweenkonzo. Abanako kuphela ukwenza ngokwezifiso ii-PCB zeempawu ezahlukeneyo ngokweemfuno zabathengi, banokubonelela ngenkxaso yobugcisa kunye nenkonzo yasemva kokuthengisa ukunceda abathengi basombulule iingxaki abadibana nazo ngexesha lokusetyenziswa.
三、Amathemba ophuhliso abavelisi bePCB abangakhokelwayo ngokusingqongileyo
Kwixesha elizayo, ugxininiso lwehlabathi ekukhuselweni kokusingqongileyo luya kuqhubeka lukhula, oluya kubangela ukuba imfuno yemarike yeePCB ezingenalo i-load ziqhubeke nokukhula. Abavelisi bePCB abangenalo ilothe ngokusingqongileyo baya kuzisa indawo ebanzi yophuhliso. Kwangaxeshanye, iya kukhuthaza abavelisi ukuba baqhubeke nokwandisa iteknoloji entsha, baphucule umgangatho wemveliso kunye nokusebenza, kwaye kwangaxeshanye ngokukhutheleyo bandise imarike ukuze babonelele abathengi abaninzi ngemveliso yePCB ekumgangatho ophezulu ehambelana nokusingqongileyo.
Njengovulindlela ohlaza kushishino lwe-elektroniki, abavelisi bePCB abangakhokeleli kokusingqongileyo bakhokela ishishini le-elektroniki ukuya kwikamva eliluhlaza nelizinzileyo ngobuchule babo obutsha bobuchwepheshe, ulwazi lokusingqongileyo, uqinisekiso lomgangatho kunye neenzuzo zenkonzo. Ngemizamo yabo, ishishini lombane liya kufumana uphuhliso olunempumelelo ngakumbi ngelixa likhusela okusingqongileyo.
