Amateka y'Iterambere rya PCB Mubushinwa

Porotipire ya PCB iva muri sisitemu yo guhanahana terefone ukoresheje igitekerezo cya “umuziki” mu ntangiriro z'ikinyejana cya 20.Ikozwe mugukata icyuma mumashanyarazi hanyuma ukagishyira hagati yimpapuro ebyiri za paraffin.

PCB mubyukuri yavutse 1930.Yakozwe no gucapa hakoreshejwe ikoranabuhanga.Byasabye ikibaho cyibikoresho nkibikoresho fatizo, bigabanywa mubunini runaka, bifatanije byibuze nuburyo bumwe bwo kuyobora, hanyuma bigashyirwa hamwe nu mwobo (nkibyobo bigize ibice, imyobo ifunga, umwobo wa metallisation, nibindi) kugirango bisimbuze chassis yibikoresho byabanjirije. ibikoresho bya elegitoronike, kandi umenye guhuza imiyoboro ya elegitoroniki, Ifite uruhare rwo kohereza relay, ni inkunga yibikoresho bya elegitoronike, bizwi nka "nyina wibicuruzwa bya elegitoroniki".

Amateka yiterambere rya PCB mubushinwa

Mu 1956, Ubushinwa bwatangiye guteza imbere PCB.

Mu myaka ya za 1960, ikibaho kimwe cyakozwe mubice, icyicaro cyibice bibiri cyakorewe mubice bito, kandi hateguwe ibice byinshi.

Mu myaka ya za 70, kubera aho amateka yabayeho muri kiriya gihe, iterambere rya tekinoroji ya PCB ryatinze, bituma ikoranabuhanga ryose ribyara umusaruro inyuma yiterambere ry’ibihugu by’amahanga.

Mu myaka ya za 1980, hashyizweho umurongo utanga umusaruro wa PCB wateye imbere, uruhande rumwe kandi rufite ibice byinshi bya PCB byaturutse mu mahanga, bizamura urwego rw'ikoranabuhanga rwa PCB mu Bushinwa.

Mu myaka ya za 90, abakora PCB b’abanyamahanga nka Hong Kong, Tayiwani n’Ubuyapani baje mu Bushinwa gushinga imishinga ihuriweho n’inganda zose, ibyo bigatuma Ubushinwa bwa PCB n’ikoranabuhanga bitera imbere cyane.

Mu 2002, ibaye iya gatatu mu gukora PCB.

Mu 2003, agaciro ka PCB n’ibicuruzwa byatumijwe mu mahanga n’ibyoherezwa mu mahanga byarenze miliyari 6 z’amadolari y’Amerika, birenga Amerika ku nshuro ya mbere kandi biba ibya kabiri mu bicuruzwa bya PCB ku isi.Umubare wibisohoka PCB wiyongereye uva kuri 8.54% muri 2000 ugera kuri 15.30%, hafi kabiri.

Mu 2006, Ubushinwa bwasimbuye Ubuyapani nk’ibikorwa binini bya PCB ku isi ndetse n’igihugu kigira uruhare runini mu iterambere ry’ikoranabuhanga.

Mu myaka yashize, inganda za PCB mu Bushinwa zagumanye umuvuduko wihuse wa 20%, zirenze kure izamuka ry’inganda za PCB ku isi.Kuva mu mwaka wa 2008 kugeza 2016, umusaruro w’inganda za PCB mu Bushinwa wazamutse uva kuri miliyari 15.037 USD ugera kuri miliyari 27.123 USD, hamwe n’ubwiyongere bw’umwaka buri mwaka bwa 7.65%, ibyo bikaba bisumba kure 1.47% by’ubwiyongere bw’isi ku isi.Amakuru ya Prismark yerekana ko muri 2019, agaciro ka PCB ku isi hose umusaruro ungana na miliyari 61.34 z'amadolari, muri yo agaciro k'ibicuruzwa bya PCB mu Bushinwa ni miliyari 32.9 z'amadolari, bingana na 53.7% by'isoko mpuzamahanga.
