鉛(qian)(qian)(qian)(qian)磚是柔軟和(he)(he)(he)延展性強的(de)弱金屬(shu)，有毒(du)，也是重金屬(shu)。用(yong)(yong)(yong)途：廣(guang)泛(fan)用(yong)(yong)(yong)于制造化工(gong)和(he)(he)(he)冶金設備。鉛(qian)(qian)(qian)(qian)合金用(yong)(yong)(yong)作軸承、活字(zi)金和(he)(he)(he)焊料等。鉛(qian)(qian)(qian)(qian)主(zhu)要(yao)通過呼吸道和(he)(he)(he)消(xiao)化道進入人(ren)(ren)體(ti)，長期(qi)接(jie)觸(chu)(chu)鉛(qian)(qian)(qian)(qian)可(ke)(ke)引(yin)起慢(man)性鉛(qian)(qian)(qian)(qian)中毒(du)，可(ke)(ke)能(neng)對身體(ti)造成職(zhi)業病。長期(qi)接(jie)觸(chu)(chu)鉛(qian)(qian)(qian)(qian)可(ke)(ke)導致腦(nao)受損(sun)，可(ke)(ke)發生貧(pin)血鉛(qian)(qian)(qian)(qian)對腎臟也有一定損(sun)害。可(ke)(ke)引(yin)起多種疾病，如貧(pin)血，高血壓(ya)，過敏癥(zheng)及昏睡等長期(qi)接(jie)觸(chu)(chu)鉛(qian)(qian)(qian)(qian)者發生白(bai)血病之危險性是一般人(ren)(ren)的(de)4倍。防(fang)(fang)止鉛(qian)(qian)(qian)(qian)中毒(du)，關鍵在于防(fang)(fang)護。合理的(de)營養措施能(neng)提(ti)高抵抗(kang)力，增強機(ji)(ji)體(ti)對有毒(du)物質(zhi)的(de)代謝解毒(du)能(neng)力，減(jian)少毒(du)物吸收(shou)并(bing)促使其轉化。1、膳食(shi)中應包含足夠量的(de)優(you)質(zhi)蛋白(bai)質(zhi)，特別是含硫氨基酸（如半胱氨酸）豐富的(de)蛋白(bai)質(zhi)，對降低(di)體(ti)內的(de)鉛(qian)(qian)(qian)(qian)濃度有利，也可(ke)(ke)減(jian)輕(qing)中毒(du)癥(zheng)狀。2、鉛(qian)(qian)(qian)(qian)接(jie)觸(chu)(chu)人(ren)(ren)群(qun)應注意補鈣(gai)。采取調配膳食(shi)鈣(gai)磷比(bi)例的(de)方法可(ke)(ke)達到降低(di)機(ji)(ji)體(ti)鉛(qian)(qian)(qian)(qian)負荷的(de)目(mu)的(de)。3、鉛(qian)(qian)(qian)(qian)接(jie)觸(chu)(chu)人(ren)(ren)群(qun)常(chang)有維(wei)(wei)生素(su)缺(que)乏，膳食(shi)調配時應選擇富含維(wei)(wei)生素(su)的(de)食(shi)物，尤其是維(wei)(wei)生素(su)C較為重要(yao)。

鉛(qian)磚的(de)煉(lian)(lian)制(zhi)過(guo)(guo)程：1.傳(chuan)統煉(lian)(lian)鉛(qian)法(fa)(fa)燒(shao)結機(ji)和煉(lian)(lian)鐵高爐是燒(shao)結機(ji)的(de)關鍵(jian)機(ji)器設(she)備(bei)，能夠各自進行氧化還(huan)原反應加工(gong)工(gong)藝，燒(shao)結全過(guo)(guo)程自身(shen)存有(you)一些缺點：燒(shao)結全過(guo)(guo)程SO2濃度值低(di)，煙塵轉換為(wei)SO2只有(you)超過(guo)(guo)90，SO2率低(di)。因為(wei)技術性(xing)完(wan)善，項(xiang)目投資少，鉛(qian)生產制(zhi)造(zao)國(guo)外依然充(chong)分發(fa)揮著關鍵(jian)功效。2.直接(jie)煉(lian)(lian)鉛(qian)法(fa)(fa)直接(jie)熔煉(lian)(lian)鉛(qian)分為(wei)閃熔和熔池：典型的(de)閃熔法(fa)(fa)是Kifsett法(fa)(fa)、Otto-Kup法(fa)(fa)、典型熔池為(wei)QSL法(fa)(fa)、口(kou)山法(fa)(fa)、ISA爐、Carl-Do法(fa)(fa)等。產品(pin)特(te)點：密度大（達到2.5），性(xing)能穩定，結實耐(nai)(nai)用(yong)(yong)，抗壓扛(kang)折，防火(huo)耐(nai)(nai)潮，耐(nai)(nai)酸堿(jian)腐蝕，價(jia)格便宜，施(shi)工(gong)方便，易于應用(yong)(yong)等特(te)點。商品(pin)主要(yao)用(yong)(yong)途：適用(yong)(yong)于充(chong)電電池、建筑涂(tu)料(liao)、焊材(cai)、有(you)機(ji)化學鉛(qian)鹽、電纜線(xian)套、滾動(dong)軸承(cheng)材(cai)料(liao)、接(jie)縫(feng)處材(cai)料(liao)、鉛(qian)合金和x光線(xian)維護材(cai)料(liao)的(de)生產制(zhi)造(zao)。

鉛(qian)(qian)磚是柔(rou)軟和延展性強(qiang)的(de)(de)(de)(de)弱金屬，有(you)(you)毒(du)(du)，也是重金屬。用途：廣泛用于(yu)制(zhi)造(zao)化工和冶(ye)金設(she)備。鉛(qian)(qian)合金用作(zuo)軸承、活(huo)字金和焊(han)料等(deng)。鉛(qian)(qian)主要通過呼(hu)吸道(dao)和消化道(dao)進(jin)入人體，長期接(jie)觸(chu)鉛(qian)(qian)可(ke)(ke)引(yin)起慢性鉛(qian)(qian)中毒(du)(du)，可(ke)(ke)能(neng)對身體造(zao)成職(zhi)業(ye)病(bing)。長期接(jie)觸(chu)鉛(qian)(qian)可(ke)(ke)導致腦受損(sun)，可(ke)(ke)發生(sheng)(sheng)貧血鉛(qian)(qian)對腎臟也有(you)(you)一(yi)定損(sun)害。可(ke)(ke)引(yin)起多(duo)種疾(ji)病(bing)，如(ru)貧血，高血壓，過敏癥及昏睡等(deng)長期接(jie)觸(chu)鉛(qian)(qian)者發生(sheng)(sheng)白(bai)血病(bing)之(zhi)危險(xian)性是一(yi)般人的(de)(de)(de)(de)4倍。防止(zhi)鉛(qian)(qian)中毒(du)(du)，關鍵在于(yu)防護。合理的(de)(de)(de)(de)營養措施能(neng)提高抵抗(kang)力，增強(qiang)機(ji)(ji)體對有(you)(you)毒(du)(du)物質(zhi)的(de)(de)(de)(de)代(dai)謝解毒(du)(du)能(neng)力，減(jian)(jian)少毒(du)(du)物吸收并促使其(qi)轉化。1、膳(shan)食(shi)中應包(bao)含(han)(han)足夠量的(de)(de)(de)(de)優(you)質(zhi)蛋(dan)白(bai)質(zhi)，特別是含(han)(han)硫(liu)氨基酸（如(ru)半胱氨酸）豐富的(de)(de)(de)(de)蛋(dan)白(bai)質(zhi)，對降(jiang)低體內的(de)(de)(de)(de)鉛(qian)(qian)濃(nong)度有(you)(you)利，也可(ke)(ke)減(jian)(jian)輕(qing)中毒(du)(du)癥狀。2、鉛(qian)(qian)接(jie)觸(chu)人群(qun)應注意補(bu)鈣。采取調(diao)配膳(shan)食(shi)鈣磷比(bi)例的(de)(de)(de)(de)方法(fa)可(ke)(ke)達到降(jiang)低機(ji)(ji)體鉛(qian)(qian)負荷的(de)(de)(de)(de)目的(de)(de)(de)(de)。3、鉛(qian)(qian)接(jie)觸(chu)人群(qun)常有(you)(you)維(wei)生(sheng)(sheng)素缺乏，膳(shan)食(shi)調(diao)配時應選擇富含(han)(han)維(wei)生(sheng)(sheng)素的(de)(de)(de)(de)食(shi)物，尤(you)其(qi)是維(wei)生(sheng)(sheng)素C較為重要。
