Abakinnyi benshi ba DIY bazabona ko ibicuruzwa bitandukanye byubuyobozi ku isoko bifashisha amabara atandukanye ya PCB.
Ibara ryinshi rya PCB ni umukara, icyatsi, ubururu, umuhondo, umutuku, umutuku, n'umuhondo.
Bamwe mubakora ibicuruzwa bakoze iterambere ryera, umutuku nandi mabara atandukanye ya PCB.

Mubitekerezo gakondo, PCB yumukara isa nkaho ihagaze kumpera yo hejuru, mugihe umutuku, umuhondo, nibindi, aribyo-bito byeguriwe Imana, nibyo?

Umuringa wumuringa wa PCB udafite abarwanya ibicuruzwa bitwikiriye okiside byoroshye iyo uhuye numwuka

Turabizi ko imbere n'inyuma ya PCB ari umuringa.Mu musaruro wa PCB, urwego rwumuringa ruzaba rufite ubuso bworoshye kandi butarinzwe ntakibazo cyakozwe muburyo bwo kongeramo cyangwa gukuramo.

Nubwo imiterere yimiti yumuringa idakora nka aluminium, fer, magnesium, ariko imbere yamazi, guhuza umuringa mwiza na ogisijeni biroroshye kuba okiside;
Kubera umwuka wa ogisijeni hamwe n’umwuka w’amazi mu kirere, hejuru yumuringa usukuye hazabaho reaction ya okiside nyuma yo guhura nikirere.

Nkuko umubyimba wumuringa uri muri PCB ari muto cyane, umuringa wa okiside uzahinduka umuyobozi mubi w'amashanyarazi, ibyo bikaba byangiza cyane amashanyarazi ya PCB yose.

Kurinda okiside y'umuringa, gutandukanya ibice byo gusudira no kudasudira bya PCB mugihe cyo gusudira, no kurinda ubuso bwa PCB, abashakashatsi bakoze igifuniko kidasanzwe.
Ipitingi irashobora gukoreshwa muburyo bworoshye hejuru ya PCB, igakora urwego rukingira umubyimba runaka kandi ikabuza umuringa guhura nikirere.
Uru rupapuro rwitwikiriye rwitwa saleder resistance layer kandi ibikoresho byakoreshejwe ni irangi ryo kugurisha.

Kubera ko bita irangi, hagomba kubaho amabara atandukanye.
Nibyo, irangi ryambere ryabagurisha irwanya irashobora kutagira ibara kandi rifite umucyo, ariko PCB ikenera gucapwa kurubaho kugirango byoroshye gusana no kuyikora.

Irangi ryabacuruzi barwanya irangi rishobora kwerekana gusa ibara ryinyuma rya PCB, niba rero ryarakozwe, risanwa cyangwa ryagurishijwe, isura ntabwo ari nziza.
Ba injeniyeri rero bongeramo amabara atandukanye kubagurisha irwanya irangi kugirango bakore PCB yumukara cyangwa umutuku cyangwa ubururu.

PCB yumukara biragoye kubona insinga, bigatuma kubungabunga bigoye

Duhereye kuriyi ngingo, ibara rya PCB ntaho rihuriye nubwiza bwa PCB.
Itandukaniro riri hagati yumukara PCB nubururu PCB, PCB yumuhondo nandi mabara PCB iri mubara ritandukanye ryamabara yo kugurisha abayagurisha kuri brush.

Niba PCB yarateguwe kandi ikorwa kimwe, ibara ntirizagira ingaruka kumikorere, nta nubwo rizagira ingaruka ku gukwirakwiza ubushyuhe.

Kubijyanye na PCB yumukara, insinga zayo zo hejuru zirapfukiranwa rwose, bikavamo ingorane zikomeye zo kubungabunga nyuma, bityo rero ni ibara ritoroheye gukora no gukoresha.

Kubwibyo, mumyaka yashize, abantu bavugurura buhoro buhoro, bareka gukoresha irangi ryumukara wirabura, kandi bagakoresha icyatsi kibisi cyijimye, umukara wijimye, ubururu bwijimye nandi marangi yo kurwanya ibicuruzwa, ikigamijwe nukworohereza gukora no kubungabunga.

Kuri iyi ngingo, tumaze gusobanura neza ikibazo cyamabara ya PCB.
Impamvu yo kugaragara "uhagarariye ibara cyangwa urwego rwo hasi" ni ukubera ko abayikora bakunda gukoresha PCB yumukara kugirango bakore ibicuruzwa byo mu rwego rwo hejuru, kandi umutuku, ubururu, icyatsi, umuhondo nibindi bicuruzwa byo mu rwego rwo hasi.

Kurangiza, ibicuruzwa bitanga ibisobanuro kumabara, ntabwo ibara ritanga ibisobanuro kubicuruzwa.

Ni izihe nyungu icyuma cyagaciro nka zahabu, ifeza gifite PCB?
Ibara rirasobanutse, reka tuganire kubyuma byagaciro kuri PCB!
Bamwe mubakora ibicuruzwa mugutezimbere ibicuruzwa byabo, bazavuga byumwihariko ko ibicuruzwa byabo byakoresheje zahabu, isahani ya feza nibindi bikorwa bidasanzwe.
None ubu buryo bukoreshwa iki?

Ubuso bwa PCB busaba ibintu byo gusudira, kandi igice cyumuringa gisabwa kugaragara kugirango gisudwe.
Ibice byerekanwe byumuringa byitwa padi, kandi padi mubisanzwe ni urukiramende cyangwa uruziga kandi bifite agace gato.

Hejuru, tuzi ko umuringa ukoreshwa muri PCB uhinduka okiside byoroshye, bityo umuringa uri kumurongo wagurishijwe uhura numwuka mugihe hashyizweho irangi ryo kurwanya ibicuruzwa.

Niba umuringa uri kuri padi urimo okiside, ntabwo bigoye gusudira gusa, ahubwo binongera ubukana, bigira ingaruka zikomeye kumikorere yibicuruzwa byanyuma.
Ba injeniyeri rero bazanye uburyo bwose bwo kurinda padi.
Nkugusiga zahabu inert, gutwikira imiti hejuru yifeza, cyangwa gutwikira umuringa na firime idasanzwe kugirango wirinde guhura nikirere.

Padiri yerekanwe kuri PCB, umuringa ugaragara neza.
Iki gice gikeneye kurindwa kugirango kirinde okiside.

Dufatiye kuri iyi ngingo, yaba zahabu cyangwa ifeza, intego yibikorwa ubwayo ni ukwirinda okiside no kurinda amakariso kugirango babashe kubona umusaruro mwiza mugihe cyo gusudira nyuma.

Ariko, gukoresha ibyuma bitandukanye bizakenera igihe cyo kubika nuburyo bwo kubika PCB ikoreshwa muruganda rutanga umusaruro.
Kubwibyo, inganda za PCB muri rusange zikoresha imashini ifunga vacuum kugirango ipakire PCB mbere yo kurangiza umusaruro wa PCB no kugeza kubakiriya kugirango barebe ko nta byangiza okiside bibaho kuri PCB kugeza kumupaka.

Mbere yuko ibice bisudira kuri mashini, abakora amakarita yubuyobozi nabo bakeneye kumenya urugero rwa okiside ya PCB, kurandura PCB ya okiside, no kwemeza umusaruro wibicuruzwa byiza.
Umuguzi wanyuma kugirango abone ikarita yubuyobozi, anyuze mubizamini bitandukanye, nubwo nyuma yigihe kinini cyo gukoresha, okiside izaboneka gusa mugucomeka no gucomeka ibice byihuza, no kuri padi kandi byarasizwe ibice, nta ngaruka.

Ko kurwanya ifeza na zahabu biri hasi, gukoresha ibyuma bidasanzwe nka feza na zahabu bizagabanya ubushyuhe butangwa mugihe cyo gukoresha PCB?

Turabizi ko ikintu kigira ingaruka kuri calorificateur ari ukurwanya amashanyarazi.
Kurwanya no kuyobora ubwabyo ibikoresho, umuyobozi uhuza ibice, uburebure bujyanye.
Uburebure bwicyuma cyumubyimba burenze munsi ya 0,01 mm, niba hakoreshejwe uburyo bwa OST (firime organic proteine) ivura padi, ntihazabaho umubyimba urenze.
Kurwanya kwerekanwa nubunini buto hafi ya zeru, cyangwa ntibishoboka kubara, kandi rwose ntabwo bigira ingaruka kubushyuhe.
