一、干電池一般能用多長時間
干電池是生活中常用的電池,像鬧鐘、遙控器之類都是用干電池供電的,那么干電池能用多久呢?
一般(ban)來說,干(gan)電(dian)(dian)(dian)池(chi)能用(yong)多長時間,要(yao)看干(gan)電(dian)(dian)(dian)池(chi)的型號,型號不(bu)同(tong),儲電(dian)(dian)(dian)容量(liang)不(bu)同(tong),使(shi)用(yong)壽(shou)命(ming)也不(bu)同(tong);此外,電(dian)(dian)(dian)器的功(gong)率和消耗情況也會影響到(dao)它的使(shi)用(yong)壽(shou)命(ming)。以常用(yong)的5號電(dian)(dian)(dian)池(chi)為例(li),一節干(gan)電(dian)(dian)(dian)池(chi)用(yong)在(zai)遙控器使(shi)用(yong)半(ban)年或者一年都沒有問題,放在(zai)一些(xie)小家電(dian)(dian)(dian)里可能也就(jiu)一兩個月左右。
二、用完的干電池是什么垃圾
垃圾分類對于環(huan)保是(shi)有(you)幫助的,干電(dian)池(chi)作(zuo)為一(yi)次性電(dian)池(chi),用完后(hou)應該如何丟棄很多朋(peng)友都搞不(bu)清楚(chu),那么干電(dian)池(chi)是(shi)什(shen)么垃圾呢?
早期的(de)(de)干電(dian)(dian)池(chi)電(dian)(dian)解液(ye)是酸(suan)性(xing)的(de)(de),讓人們擔心(xin)干電(dian)(dian)池(chi)污染的(de)(de)主要(yao)原因(yin)是其(qi)內部含(han)有諸多化學物質:重(zhong)金屬汞(gong)、鉛、鎘等。干電(dian)(dian)池(chi)中的(de)(de)鋅容易發生析氫反應生成氫氣,需要(yao)添加汞(gong)來(lai)(lai)阻隔(ge)鋅和電(dian)(dian)解液(ye),所以(yi)在(zai)以(yi)前(qian)的(de)(de)很長一段時間干電(dian)(dian)池(chi)是被視作有害垃圾(ji)來(lai)(lai)處理的(de)(de)。
不過現在市面上主流的干電池基本都是無汞(gong)的,主要成分為:鋅、二氧化錳、氫氧化鉀,不含有或僅含有微量(liang)汞(gong),基本不會對人(ren)和(he)環境造成傷害,按照現行(xing)垃(la)圾分類標準來說,屬于(yu)其他(ta)垃(la)圾,廢棄時投入(ru)到其他(ta)垃(la)圾桶中就(jiu)好了(le)。
需(xu)要注意的是(shi),除(chu)了無汞干電(dian)(dian)(dian)池(chi)(chi)(chi)外,像紐扣電(dian)(dian)(dian)池(chi)(chi)(chi)、充電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)、手機(ji)電(dian)(dian)(dian)池(chi)(chi)(chi)等(deng)鉛蓄(xu)電(dian)(dian)(dian)池(chi)(chi)(chi)和鎳(nie)鎘電(dian)(dian)(dian)池(chi)(chi)(chi),都是(shi)有害垃圾(ji)(ji),需(xu)要放到有害垃圾(ji)(ji)桶中,可(ke)將其集中放置在社區、酒店賓館(guan)、學校、大(da)型商(shang)場超市等(deng)設置的電(dian)(dian)(dian)池(chi)(chi)(chi)回收箱(xiang)或有害垃圾(ji)(ji)桶,由專業回收機(ji)構(gou)收集。
