Nantoni na inokonakaliswa kukusetyenziswa rhoqo, ngakumbi iimveliso zombane. Nangona kunjalo, izinto ezonakalisiweyo azichithi ngokupheleleyo kwaye zinokuphinda zisetyenziswe kwakhona, njengoko kunjalo PCB. Ngapha koko, ngenkqubela phambili yenzululwazi kunye netekhnoloji, inani leemveliso ze-elektroniki lenyuke kakhulu, nto leyo icuthe ubomi babo benkonzo. Iimveliso ezininzi zilahlwa ngaphandle komonakalo, zikhokelela kwinkunkuma enkulu.

Iimveliso kumzi mveliso we-elektroniki zihlaziywa ngokukhawuleza okukhulu, kwaye inani lePCBS elahliweyo liyothusa. Unyaka ngamnye, i-UK ineetoni ezingama-50,000 100,000 zenkunkuma ye-PCBS, ngelixa iTaiwan ineetoni ezingama-XNUMX. Ukurisayikilisha ngumgaqo wokugcina izixhobo kunye nemveliso eluhlaza. Ngaphandle koko, ezinye izinto ezikwiimveliso ze-elektroniki ziya kuba yingozi kwindalo esingqongileyo, ngenxa yoko ukuphinda kusetyenziswe kwakhona kubalulekile.

Izinyithi eziqulethwe kwi-PCB zibandakanya izinyithi eziqhelekileyo: i-aluminium, ubhedu, isinyithi, i-nickel, ilothe, i-tin kunye ne-zinc, njl. Izitye zexabiso: igolide, ipalladium, iplatinam, isilivere, njl. Rare iintsimbi, selenium njalo njalo. I-PCB ikwanenani elikhulu le-polymer ngokuthe ngqo okanye ngokungathanga ngqo kwimveliso yepetroleum, enexabiso eliphezulu le-calorific, inokusetyenziselwa ukuvelisa amandla, kodwa kunye nokuveliswa kweemveliso ezinxulumene nemichiza, uninzi lwezixhobo zinetyhefu kwaye ziyingozi, ukuba ilahliwe ziya kubangela ungcoliseko olukhulu.

Itemplate zePCB zenziwe ngezinto ezininzi ezinokuphinda zisetyenziswe nokuba azisetyenziswanga kakuhle. Ke, ukuphinda usebenzise kwakhona, sazisa amanyathelo ayo:

1. Susa i-lacquer

I-PCB ifakwe isinyithi sokhuselo, kwaye inyathelo lokuqala lokurisayikilisha kukususa ipeyinti. Ipeyinti yokususa inokususa ipeyinti yendalo kunye nokususa ipeyinti enealkali, into yokuthambisa ipeyinti engafunekiyo inetyhefu, iyingozi emzimbeni womntu nakwindawo esingqongileyo, inokusebenzisa isodiyam hayidroksayidi, umhlwa intsholongwane kunye nokunye ukutshisa kobushushu.

2. Ukophuka

Emva kokuba PCB isuswe, iya kwaphulwa, kuquka igalelo yokutyunyuzwa, extrusion yokutyumza kunye uchebe kutyunyuzwa. Eyona nto isetyenziswa ngokuxhaphakileyo kukushisa okubandayo okuqhekeza ubuchwephesha obunokupholisa izinto ezinzima kwaye uzityumze emva kokufakwa, ukuze isinyithi kunye nesinyithi sihlukaniswe ngokupheleleyo.

3. Ukuhlela

Imathiriyeli emva kokutyunyuzwa ifuna ukwahlulwa ngokobuninzi bayo, ubungakanani bamasuntswana, ukuhambisa ngemagnethi, ukuqhuba kombane kunye nezinye izinto zamacandelo ayo, zihlala zihlelwa ngohlobo olomileyo nolumanzi. Ukwahlukana okomileyo kubandakanya ukomiswa okomileyo, ukwahlukana ngemagnethi, i-electrostatic, ukuxinana kunye nokuhlukana okwangoku, njl. Ukwahlukana okumanzi kunokwahlulahlula i-hydrocyclone, flotation, hydraulic shaker, njl. Kwaye emva koko unokuyisebenzisa kwakhona.
