Ngokutsho kwedatha, ibhetri enye iqhosha inokungcolisa iilitha ezingama-600000 zamanzi, ezinokusetyenziswa ngumntu ubomi bonke. Ukuba icandelo lebhetri elinguNombolo 1 liphoswa entsimini apho kulinywa khona izityalo, umhlaba osisikwere semitha esi-1 ojikeleze le nkunkuma uya kuba ludlolo. Kwakutheni ukuze kubenje? Ngenxa yokuba ezi bhetri zenkunkuma ziqulethe isixa esikhulu sesinyithi esinzima. Umzekelo: i-zinc, ilothe, i-cadmium, i-mercury, njl njl. Ezi ntsimbi zinzima zingena emanzini zize zifunxwe ziintlanzi kunye nezityalo. Ukuba abantu batya ezi ntlanzi zingcolisekileyo, i-shrimp kunye nezityalo, baya kuba netyhefu ye-Mercury kunye nezifo ze-nervous system, kunye nesantya sokufa ukuya kuma-40%. I-Cadmium ichongiwe njengeKlasi ye-1A yeCarcinogen.

Iibhetri zenkunkuma zineentsimbi ezinzima ezifana nemercury, cadmium, manganese, kunye nelothe. Xa umphezulu weebhetri ugqwala ngenxa yokukhanya kwelanga kunye nemvula, amacandelo ensimbi enzima ngaphakathi aya kungena emhlabeni kunye namanzi aphantsi. Ukuba abantu batya izityalo eziveliswe kumhlaba ongcolisekileyo okanye basele amanzi angcolileyo, ezi zinyithi zinetyhefu ziya kungena emzimbeni womntu kwaye zibeke kancinci kancinci, zibeka isoyikiso esikhulu kwimpilo yabantu.

Emva kokuba i-mercury kwiibhetri zenkunkuma ziphuphuma, ukuba ingena kwiiseli zengqondo yomntu, inkqubo ye-nervous iya konakala kakhulu. I-Cadmium inokubangela umonakalo kwisibindi kunye nezintso, kwaye kwiimeko ezinzima, ukuguqulwa kwamathambo. Ezinye iibhetri zenkunkuma zikwanazo neasidi kunye nelothe yentsimbi enzima, enokubangela ungcoliseko lomhlaba namanzi ukuba zivuza kwindalo, ekugqibeleni ibeka ingozi ebantwini.
Indlela yokunyanga ibhetri

1. Ukuhlelwa
Gcoba inkunkuma esetyenzisiweyo, hluba iqokobhe le-zinc kunye nentsimbi esezantsi yebhetri, khupha ikepusi yobhedu kunye nentonga yegraphite, kwaye into eseleyo emnyama ngumxube weManganese dioxide kunye ne-ammonium chloride esetyenziswa njengondoqo webhetri. Qokelela izinto ezingentla ngokwahlukeneyo kwaye uzisetyenzise ukufumana izinto eziluncedo. Intonga yegraphite iyahlanjwa, yomiswe, ize isetyenziswe njenge-electrode.

2. I-zinc granulation
Geza iqokobhe le-zinc elikhutshiweyo kwaye ulibeke kwimbiza yentsimbi. Yitshise ukuze inyibilike kwaye uyigcine ishushu kwiiyure ezi-2. Susa umaleko ongaphezulu we-scum, uwugalele ukuba uphole, kwaye uwubeke kwi-iron plate. Emva kokuqina, iinqununu ze-zinc zifunyenwe.

3. Ukurisayikilisha amaphepha obhedu
Emva kokuthambisa i-cap yobhedu, yihlambe ngamanzi ashushu, kwaye emva koko wongeze inani elithile le-10% ye-asidi ye-sulfuric ukubilisa imizuzu engama-30 ukususa umaleko we-oxide ongaphezulu. Susa, uhlambe, kwaye womise ukufumana umcu wobhedu.

4. Ukubuyiswa kwe-ammonium chloride
Faka into emnyama kwi-cylinder, yongeza i-60oC amanzi afudumele kwaye ugxobhoze iyure eli-1 ukunyibilikisa yonke i-ammonium chloride emanzini. Mayime ngxi, ihluze, kwaye ihlambe intsalela yesihluzo kabini, kwaye uqokelele utywala oomama; Emva kokuba utywala lukamama luyiVacuum distillation de kuvele ifilimu emhlophe yekristale kumphezulu, iyapholiswa kwaye ihluzwe ukufumana iikristale ze-ammonium chloride, kwaye utywala bukamama buphinde busetyenziswe.

5. Ukubuyiswa kweManganese dioxide
Hlamba intsalela yesihluzi esihluziweyo ngamanzi amaxesha amathathu, uyihluze, ubeke ikhekhe lokucoca embizeni kwaye uyiqhume ukuze ususe ikhabhoni encinci kunye nezinye izinto eziphilayo, emva koko uyibeke emanzini kwaye uyishukumise ngokupheleleyo imizuzu engama-30, ihluze, yomisa ikhekhe lokucoca kwi-100-110oC ukufumana i-Manganese dioxide emnyama.

6. Ukuqina, ukungcwatywa nzulu, kunye nokugcinwa kwimigodi engasasetyenziswayo
Ngokomzekelo, umzi-mveliso waseFransi ukhupha i<em>nickel ne<em>cadmium kuyo, ethi emva koko isetyenziswe ekwenzeni intsimbi, ngoxa i<em>cadmium iphinda isetyenziswe ekuveliseni iibhetri. Ezinye iibhetri zenkunkuma ngokubanzi zithuthelwa kwiindawo zokulahla inkunkuma enetyhefu ekhethekileyo kunye neHazardous, kodwa lo mkhuba awubizi kakhulu kuphela, kodwa ubangela inkunkuma, kuba kusekho izinto ezininzi eziluncedo ezinokusetyenziswa njengezinto eziluhlaza.
