方(fang)鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)礦(PbS)直到今天(tian)都是(shi)(shi)(shi)(shi)人(ren)們(men)提取鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)的(de)(de)(de)主(zhu)要來源(yuan)。遠(yuan)古時代(dai)人(ren)們(men)偶然(ran)把方(fang)鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)礦投(tou)進篝火中(zhong)(zhong)(zhong)(zhong)，它首先被(bei)燒成(cheng)氧(yang)化(hua)物(wu)，然(ran)后受(shou)到碳(tan)的(de)(de)(de)還(huan)原，形(xing)成(cheng)了(le)金屬鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)。鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)為帶藍色的(de)(de)(de)銀白(bai)色重金屬，它有(you)(you)毒性(xing)，是(shi)(shi)(shi)(shi)一種有(you)(you)延伸性(xing)的(de)(de)(de)主(zhu)族金屬。熔(rong)點327.502℃，沸(fei)點1740℃，密度11.3437g/cm^3，硬(ying)度1.5，質地柔軟(ruan)，抗張強度小。鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)是(shi)(shi)(shi)(shi)人(ren)類早使用(yong)的(de)(de)(de)金屬之一，公元前3000年，人(ren)類已會從礦石(shi)中(zhong)(zhong)(zhong)(zhong)熔(rong)煉鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)。鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)在地殼(ke)中(zhong)(zhong)(zhong)(zhong)的(de)(de)(de)含(han)量為0.0016%，主(zhu)要礦石(shi)是(shi)(shi)(shi)(shi)方(fang)鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)礦。鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)在自(zi)然(ran)界(jie)中(zhong)(zhong)(zhong)(zhong)有(you)(you)4種穩定(ding)同位(wei)素：鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)204、206、207、208，還(huan)有(you)(you)20多(duo)種放射性(xing)同位(wei)素。金屬鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)在空氣中(zhong)(zhong)(zhong)(zhong)受(shou)到氧(yang)、水(shui)和二氧(yang)化(hua)碳(tan)作(zuo)用(yong)，其表面(mian)會很(hen)(hen)快(kuai)氧(yang)化(hua)生成(cheng)保護(hu)薄膜;在加熱下(xia)，鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)能(neng)(neng)很(hen)(hen)快(kuai)與(yu)氧(yang)、硫、鹵(lu)素化(hua)合;鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)與(yu)冷鹽(yan)酸(suan)、冷硫酸(suan)幾乎不(bu)起(qi)作(zuo)用(yong)，能(neng)(neng)與(yu)熱或濃(nong)鹽(yan)酸(suan)、硫酸(suan)反(fan)應;鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)與(yu)稀硝酸(suan)反(fan)應，但與(yu)濃(nong)硝酸(suan)不(bu)反(fan)應;鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)能(neng)(neng)緩慢溶于(yu)強堿性(xing)溶液。鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)在地殼(ke)中(zhong)(zhong)(zhong)(zhong)含(han)量不(bu)大(da)，自(zi)然(ran)界(jie)中(zhong)(zhong)(zhong)(zhong)存在很(hen)(hen)少量的(de)(de)(de)天(tian)然(ran)鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)。但由于(yu)含(han)鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)礦物(wu)聚集，熔(rong)點又很(hen)(hen)低(328℃)，使鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)在遠(yuan)古時代(dai)就(jiu)被(bei)人(ren)們(men)所利(li)用(yong)了(le)。方(fang)鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)礦(PbS)直到今天(tian)都是(shi)(shi)(shi)(shi)人(ren)們(men)提取鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)的(de)(de)(de)主(zhu)要來源(yuan)。遠(yuan)古時代(dai)人(ren)們(men)偶然(ran)把方(fang)鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)礦投(tou)進篝火中(zhong)(zhong)(zhong)(zhong)，它首先被(bei)燒成(cheng)氧(yang)化(hua)物(wu)，然(ran)后受(shou)到碳(tan)的(de)(de)(de)還(huan)原，形(xing)成(cheng)了(le)金屬鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)。對于(yu)鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)我們(men)要明白(bai)鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)阻擋的(de)(de)(de)是(shi)(shi)(shi)(shi)放射性(xing)物(wu)質發出的(de)(de)(de)射線不(bu)是(shi)(shi)(shi)(shi)放射性(xing)物(wu)質.下(xia)面(mian)我們(men)將為您介紹一下(xia)鉛(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)的(de)(de)(de)防輻(fu)射原理分析.

防輻(fu)(fu)射(she)鉛(qian)(qian)(qian)磚(zhuan)具備耐(nai)腐(fu)蝕(shi)，耐(nai)腐(fu)蝕(shi)性，跟隨社會經濟發展(zhan)(zhan)的(de)(de)(de)飛(fei)速發展(zhan)(zhan)，在耐(nai)酸(suan)性自然環境工(gong)程施工(gong)、醫療器材(cai)防輻(fu)(fu)射(she)、CT室射(she)線防護(hu)(hu)等(deng)多層面被廣泛(fan)運用(yong)(yong)(yong)，為(wei)有(you)利于(yu)人們更(geng)強(qiang)的(de)(de)(de)應用(yong)(yong)(yong)，以(yi)往(wang)還(huan)要對它開展(zhan)(zhan)好的(de)(de)(de)維(wei)(wei)(wei)護(hu)(hu)和保(bao)養(yang)。防輻(fu)(fu)射(she)鉛(qian)(qian)(qian)磚(zhuan)的(de)(de)(de)運用(yong)(yong)(yong)范疇十(shi)分(fen)寬闊，由于(yu)品(pin)質(zhi)(zhi)輕，壽命長，外(wai)型別具一格等(deng)很多優點，近(jin)些年鉛(qian)(qian)(qian)板的(de)(de)(de)應用(yong)(yong)(yong)十(shi)分(fen)普遍。為(wei)了確(que)保(bao)鉛(qian)(qian)(qian)磚(zhuan)的(de)(de)(de)品(pin)質(zhi)(zhi)，增(zeng)加(jia)鉛(qian)(qian)(qian)磚(zhuan)的(de)(de)(de)使用(yong)(yong)(yong)期，鉛(qian)(qian)(qian)磚(zhuan)的(de)(de)(de)維(wei)(wei)(wei)護(hu)(hu)保(bao)養(yang)是十(shi)分(fen)關鍵的(de)(de)(de)。維(wei)(wei)(wei)護(hu)(hu)保(bao)養(yang)機器設備不(bu)能(neng)存在裂開和破壞性造成的(de)(de)(de)彎曲不(bu)能(neng)松動、晃動當不(bu)能(neng)符合(he)規定(ding)應用(yong)(yong)(yong)尺寸，拆換或維(wei)(wei)(wei)修.但是大家都是要搞好鉛(qian)(qian)(qian)磚(zhuan)的(de)(de)(de)維(wei)(wei)(wei)護(hu)(hu)保(bao)養(yang)維(wei)(wei)(wei)護(hu)(hu)保(bao)養(yang)工(gong)作(zuo)(zuo)中，那樣(yang)才可以(yi)應用(yong)(yong)(yong)更(geng)長期，作(zuo)(zuo)用(yong)(yong)(yong)也不(bu)容(rong)易減少。
