Dukurikije amakuru, bateri imwe ya buto irashobora kwanduza litiro 600000 yamazi, ashobora gukoreshwa numuntu ubuzima bwe bwose. Niba igice cya bateri No1 kijugunywe mumurima aho ibihingwa bihingwa, metero kare 1 yubutaka buzengurutse iyi batiri yimyanda izaba ingumba. Kuki byabaye gutya? Kuberako batteri yimyanda irimo ubwinshi bwibyuma biremereye. Kurugero: zinc, gurş, cadmium, mercure, nibindi. Ibyo byuma biremereye byinjira mumazi kandi bigatwarwa n amafi nibihingwa. Niba abantu barya aya mafi yanduye, urusenda n'ibihingwa, bazarwara uburozi bwa Mercury n'indwara zo mu mitsi yo hagati, aho impfu zigera kuri 40%. Cadmium izwi nka Kanseri yo mu cyiciro cya 1A.

Batteri yimyanda irimo ibyuma biremereye nka mercure, kadmium, manganese, na gurş. Iyo ubuso bwa bateri bwangiritse kubera urumuri rw'izuba n'imvura, ibyuma biremereye imbere bizinjira mubutaka n'amazi yo mu butaka. Niba abantu barya ibihingwa bikorerwa kubutaka bwanduye cyangwa bakanywa amazi yanduye, ibyo byuma biremereye byinjira mumubiri wumuntu hanyuma bikabikwa buhoro, bikabangamira ubuzima bwabantu.

Nyuma ya mercure muri bateri yimyanda irenze, iyo yinjiye mu ngirabuzimafatizo zubwonko bwabantu, sisitemu yimitsi izaba yangiritse cyane. Cadmium irashobora kwangiza umwijima nimpyiko, kandi mugihe gikomeye, guhindura amagufwa. Batiyeri zimwe na zimwe zirimo aside hamwe nicyuma kiremereye, gishobora gutera ubutaka n’amazi iyo byinjiye muri kamere, amaherezo bikaba byangiza abantu.
Uburyo bwo kuvura bateri

1. Ibyiciro
Kumenagura bateri yimyanda itunganijwe neza, kwiyambura igikonjo cya zinc hamwe nicyuma cyo hasi cya batiri, fata umuringa wumuringa ninkoni ya grafite, naho ibintu byirabura bisigaye ni uruvange rwa dioxyde ya Manganese na chloride amonium ikoreshwa nkibikoresho bya batiri. Kusanya ibintu byavuzwe haruguru ukabitunganya kugirango ubone ibintu byingirakamaro. Inkoni ya grafite irakaraba, ikuma, hanyuma igakoreshwa nka electrode.

2. Zinc granulation
Koza igikonjo cya zinc cyambuwe hanyuma ubishyire mu nkono y'icyuma. Shyushya kugirango ushonge kandi ugumane amasaha 2. Kuraho igice cyo hejuru cya scum, uyisuke kugirango ukonje, hanyuma uyijugunye ku isahani yicyuma. Nyuma yo gukomera, ibice bya zinc birabonetse.

3. Gusubiramo impapuro z'umuringa
Nyuma yo gusibanganya umuringa wumuringa, kwoza namazi ashyushye, hanyuma ushyiremo umubare runaka wa 10% acide sulfurike kugirango ubire muminota 30 kugirango ukureho igice cya oxyde. Kuraho, gukaraba, no gukama kugirango ubone umurongo wumuringa.

4. Kugarura chloride ya amonium
Shira ibintu byirabura muri silinderi, ongeramo 60oC amazi ashyushye hanyuma ukangure kumasaha 1 kugirango ushongeshe chloride ya amonium yose mumazi. Reka ihagarare, uyungurure, kandi woze ibisigazwa bya filteri kabiri, hanyuma ukusanyirize inzoga za nyina; Nyuma yinzoga ya nyina ni Vacuum distillation kugeza firime yera ya kirisiti igaragara hejuru, irakonjeshwa ikayungururwa kugirango ibone kristu ya amonium chloride, kandi inzoga za nyina zongera gukoreshwa.

5. Kugarura dioxyde ya Manganese
Karaba ibisigazwa byayungurujwe hamwe namazi inshuro eshatu, uyungurure, shyira agatsima kayunguruzo mumasafuriya hanyuma uyisunike kugirango ukureho karubone nkeya nibindi bintu kama, hanyuma ubishyire mumazi hanyuma ubireke byuzuye muminota 30, ubungurure, kuma akayunguruzo kuri 100-110oC kugirango ubone dioxyde de Manganese.

6. Gukomera, gushyingura byimbitse, no kubika mu birombe byatawe
Kurugero, uruganda rwo mubufaransa rukuramo nikel na kadmium, hanyuma bigakoreshwa mugukora ibyuma, mugihe kadmium yongeye gukoreshwa mugukora bateri. Ahasigaye bateri yimyanda ijyanwa mumyanda idasanzwe yuburozi nuburozi, ariko iyi myitozo ntabwo igura amafaranga menshi gusa, ahubwo inatera imyanda, kuko haracyari ibikoresho byinshi byingirakamaro bishobora gukoreshwa nkibikoresho fatizo.
