Njengoba ubuchwepheshe buthuthuka, isidingo samabhodi esekethe aphrintiwe (PCBs) siyaqhubeka nokukhula. Ama-PCB ayizingxenye ezibalulekile emishinini kagesi exhumanisa izingxenye ezihlukahlukene ukuze kwakhe amasekhethi asebenzayo. Inqubo yokukhiqiza ye-PCB ibandakanya izinyathelo eziningi, esinye sezigaba ezibalulekile ukuqopha, okusivumela ukuthi sisuse ithusi elingadingekile ebusweni bebhodi. Ngenkathi izisombululo ze-etch zentengiso zitholakala kalula, ungaphinda uzenzele ezakho izixazululo ze-PCB etch ekhaya. Kule bhulogi, sizokuqondisa ngenqubo, sikunikeze izixazululo ezingabizi nezisebenziseka kalula zazo zonke izidingo zakho zokushumeka ze-PCB.
impahla eluhlaza:
Ukwakha isixazululo se-PCB etching ekhaya, uzodinga izithako ezilandelayo:
1. I-hydrogen peroxide (3%): Into evamile yasendlini esebenza njenge-oxidizing.
2. I-Hydrochloric acid (i-hydrochloric acid): Itholakala ezitolo eziningi ze-hardware, isetshenziselwa ukuhlanza.
3. Usawoti wetafula (i-sodium chloride): Enye into evamile yasendlini engathuthukisa inqubo yokunamathisela.
4. Amanzi acwecwe: asetshenziselwa ukuhlambulula isixazululo nokugcina ukufana kwawo.
uhlelo:
Manje, ake singene enqubweni yokudala isixazululo se-PCB etching ekhaya:
1. Ukuphepha Kuqala: Ngaphambi kokuthi uqale, qiniseka ukuthi unempahla yokuphepha edingekayo njengamagilavu, izibuko, nendawo enomoya omuhle. Amakhemikhali angaba yingozi uma engaphathwa kahle, ngakho sebenzisa ukuqapha kuyo yonke inqubo.
2. Isixazululo esixutshiwe: Faka u-100ml we-hydrogen peroxide (3%), u-30ml we-hydrochloric acid no-15g kasawoti esitsheni sengilazi. Hlanganisa kahle ingxube kuze kube yilapho usawoti uchithwa ngokuphelele.
3. I-Dilution: Ngemva kokuxuba izixazululo eziyinhloko, hlambulula ngamanzi angaba ngu-300 ml wamanzi acwecwe. Lesi sinyathelo sibalulekile ekugcineni ukufana kwe-etch efanele.
4. Inqubo yokunamathisela: Gcobisa i-PCB kusixazululo sokunamathisela, qiniseka ukuthi icwile ngokuphelele. Gcoba ngobumnene ikhambi ngezikhathi ezithile ukuze ukhuthaze ukufakwa okufanayo. Isikhathi se-Etch singahluka kuye ngobunkimbinkimbi kanye nogqinsi lwemikhondo yethusi, kodwa ngokuvamile siyimizuzu eyi-10 kuye kwengama-30.
5. Hlanza futhi Uhlanze: Ngemva kwesikhathi esifiselekayo sokuqopha, susa i-PCB kusixazululo se-etching bese ugeza kahle ngaphansi kwamanzi agobhozayo ukuze umise inqubo yokuqopha. Sebenzisa ibhulashi elithambile noma isipontshi ukuhlanza noma yikuphi ukungcola okusele endaweni yebhodi.
Ukudala isixazululo sakho se-PCB etching ekhaya kunikeza enye indlela ethengekayo nesebenziseka kalula kunezinketho zentengiso. Nokho, kubalulekile ukukhumbula ukuthi ukusebenza ngamakhemikhali kudinga izinyathelo zokuphepha ezifanele. Hlala uphatha lezi zinto endaweni enomoya omuhle futhi ugqoke izinto zokuzivikela. Izixazululo ze-PCB etching enziwe ekhaya zenza amaphrojekthi we-DIY electronics abe lula ngenkathi yonga imali futhi yehlisa ukumosha. Ngakho-ke vula ubuhlakani bakho bese ugxumela emhlabeni we-PCB etching kusukela ekunethezekeni kwekhaya lakho!
