一、電池片回收有什么作用

1、減少對環境的污染壓力

如今，隨著社會經濟的發展，社會環境正面臨嚴峻的考驗。一方面，不可生資源的數量正在減少。另一方面，一些污染現象還在不斷破壞環境的平衡結構。比如說部分人隨意丟棄廢舊的電池片。這種(zhong)情況下，會對環境(jing)的(de)土壤、水源等產生(sheng)嚴重危害。

2、提高資源的使用效率

廢舊電(dian)池片(pian)并(bing)不(bu)是(shi)沒有(you)用(yong)途，其實，廢舊電(dian)池片(pian)可以被再次利用(yong)，從(cong)而可以提高資(zi)(zi)源(yuan)的(de)使(shi)用(yong)效率，尤其是(shi)一些(xie)不(bu)可再利用(yong)的(de)資(zi)(zi)源(yuan)能(neng)夠(gou)得到較(jiao)好的(de)保護(hu)，既能(neng)夠(gou)延(yan)長資(zi)(zi)源(yuan)的(de)使(shi)用(yong)時限，還能(neng)降低(di)部分物資(zi)(zi)對環境造成的(de)污染。

3、節省了一定的生產成本

從電池(chi)片回(hui)收公司了(le)解到，他(ta)們(men)使(shi)用廢舊電池(chi)為原料，生產新(xin)的電池(chi)成本得到了(le)大幅度降低，實現(xian)了(le)“雙贏(ying)”的局(ju)面。

在日常的(de)(de)工作生(sheng)活中，建議大(da)家要妥(tuo)善處(chu)理好廢(fei)(fei)舊電池(chi)(chi)片，尤其是不(bu)能(neng)隨(sui)意處(chu)置，比如(ru)說丟棄在垃圾堆里，那樣將會造成(cheng)很大(da)的(de)(de)危害，盡可(ke)能(neng)將廢(fei)(fei)舊電池(chi)(chi)片收(shou)集(ji)起來送到電池(chi)(chi)片回收(shou)公(gong)司，在實現廢(fei)(fei)舊電池(chi)(chi)片回收(shou)的(de)(de)同時，對保(bao)護環境起到了很好的(de)(de)作用。

三、太陽能電池片怎么進行回收

電池(chi)片可(ke)以(yi)回收，可(ke)以(yi)從太(tai)陽能電池(chi)中(zhong)回收純硅。

太陽能電池主要含有硅（約91.6%重量）。它還包含其他材料，例如底層的鋁，頂層的銀電極，以及頂層的鉛和抗反射涂層。p型和n型硅晶片位于抗反射涂層和鋁層之間。太陽能電池片藍色層(ceng)是抗反射(she)涂層(ceng)（SiNx），白線(xian)是銀(yin)電(dian)極。太(tai)陽能電(dian)池片的底部為(wei)鋁層(ceng)。為(wei)了(le)去除這些材(cai)料(liao)（鋁、銀(yin)、鉛(qian)和抗反射(she)涂層(ceng)），需使用化學處理方(fang)法(fa)。

首先，氫(qing)氟(fu)(fu)(fu)酸或氫(qing)氟(fu)(fu)(fu)酸與其他化學(xue)品的(de)(de)混(hun)合物(wu)用(yong)于去(qu)除太陽能電池的(de)(de)抗反射(she)涂(tu)層(ceng)(ceng)、銀(yin)、鉛和pn結(jie)。由于氫(qing)氟(fu)(fu)(fu)酸是劇毒和腐(fu)蝕性(xing)化學(xue)品，因此在目前的(de)(de)工作(zuo)中不再使(shi)用(yong)氫(qing)氟(fu)(fu)(fu)酸。每一(yi)層(ceng)(ceng)都使(shi)用(yong)化學(xue)處(chu)理一(yi)層(ceng)(ceng)一(yi)層(ceng)(ceng)地去(qu)除。

用(yong)濃NaOH溶(rong)(rong)液處(chu)理(li)后去除鋁層。在反應(ying)過(guo)程中(zhong)形成的(de)氫氣被收集(ji)在一個腔室中(zhong)并(bing)可用(yong)作燃料。通過(guo)過(guo)濾(lv)從NaOH溶(rong)(rong)液中(zhong)分(fen)(fen)離(li)氫氧(yang)(yang)化(hua)(hua)鋁。類似地，通過(guo)用(yong)HNO3處(chu)理(li)去除銀(yin)(yin)和(he)鉛(qian)。收集(ji)釋(shi)放的(de)NO2并(bing)可用(yong)于生產硝酸。分(fen)(fen)離(li)硝酸銀(yin)(yin)，溶(rong)(rong)液用(yong)HCl處(chu)理(li)，形成氯(lv)化(hua)(hua)銀(yin)(yin)。濾(lv)出沉淀(dian)(dian)的(de)氯(lv)化(hua)(hua)銀(yin)(yin)。此外，將溶(rong)(rong)液用(yong)NaOH處(chu)理(li)以從溶(rong)(rong)液中(zhong)分(fen)(fen)離(li)鉛(qian)化(hua)(hua)合物（PbO）。氧(yang)(yang)化(hua)(hua)鉛(qian)轉化(hua)(hua)為(wei)氫氧(yang)(yang)化(hua)(hua)鉛(qian)，過(guo)濾(lv)沉淀(dian)(dian)的(de)氫氧(yang)(yang)化(hua)(hua)鉛(qian)。
