鉛(qian)(qian)(qian)磚 工(gong)業探傷鉛(qian)(qian)(qian)磚 防輻(fu)(fu)(fu)射(she)鉛(qian)(qian)(qian)磚鉛(qian)(qian)(qian)磚基(ji)本上是具(ju)(ju)有自鎖(suo)互鎖(suo)能(neng)(neng)力的(de)矩(ju)形框磚，關鍵在輻(fu)(fu)(fu)射(she)源(yuan)可能(neng)(neng)性(xing)相當大的(de)場所(suo)或流程(cheng)中(zhong)用以生產制造(zao)屏蔽墻。鉛(qian)(qian)(qian)磚對臨時性(xing)或性(xing)屏蔽/存儲(chu)狀況(kuang)是一類便利(li)的(de)解決方(fang)法。鉛(qian)(qian)(qian)磚容(rong)易(yi)疊堆、展開和(he)重新(xin)配置，可提供較大程(cheng)度(du)的(de)保障。鉛(qian)(qian)(qian)磚由(you)的(de)鉛(qian)(qian)(qian)做成，具(ju)(ju)有規范的(de)硬度(du)，表面(mian)層平坦光潔，即使在銳利(li)直角的(de)狀況(kuang)下(xia)，也能(neng)(neng)保持(chi)很好(hao)的(de)齊(qi)平的(de)安裝(zhuang)。鉛(qian)(qian)(qian)磚為(wei)實驗室(shi)和(he)工(gong)作場地(墻壁安裝(zhuang))提供放射(she)性(xing)物質輻(fu)(fu)(fu)射(she)源(yuan)的(de)保障。自鎖(suo)互鎖(suo)鉛(qian)(qian)(qian)塊使其他尺寸的(de)保障墻和(he)屏蔽室(shi)的(de)支(zhi)豎、更改和(he)重新(xin)配置變得容(rong)易(yi)。鉛(qian)(qian)(qian)磚具(ju)(ju)有較強的(de)防腐蝕，耐(nai)堿(jian)性(xing)耐(nai)堿(jian)，耐(nai)堿(jian)性(xing)環(huan)境工(gong)程(cheng)施工(gong)、醫用抗輻(fu)(fu)(fu)射(she)，X光，CT檢查室(shi)防輻(fu)(fu)(fu)射(she)材料、變重、隔音(yin)等眾多方(fang)面(mian)。通常國內制造(zao)的(de)鉛(qian)(qian)(qian)磚純度(du)為(wei)99.9%以上為(wei)標準產品相對密度(du)為(wei)11.34克/立方(fang)厘米。

主要(yao)用(yong)(yong)途跟(gen)優點鉛(qian)(qian)(qian)(qian)磚為實驗室和工作環(huan)境(墻(qiang)壁(bi)裝配)提供放射(she)性(xing)輻射(she)的(de)(de)(de)保(bao)護(hu).互鎖(suo)鉛(qian)(qian)(qian)(qian)塊(kuai)使任何尺寸的(de)(de)(de)保(bao)護(hu)墻(qiang)和屏蔽室的(de)(de)(de)支豎、改變(bian)(bian)和重(zhong)(zhong)新(xin)部署變(bian)(bian)得容易。適用(yong)(yong)范圍鉛(qian)(qian)(qian)(qian)磚基本(ben)上就是具有(you)互鎖(suo)能(neng)(neng)力的(de)(de)(de)矩形磚。主要(yao)在輻射(she)可能(neng)(neng)性(xing)非常(chang)大的(de)(de)(de)場所或(huo)(huo)過程(cheng)(cheng)中用(yong)(yong)于制(zhi)造屏蔽墻(qiang)。鉛(qian)(qian)(qian)(qian)磚對臨(lin)時或(huo)(huo)屏蔽/儲存情況是一種便利的(de)(de)(de)解決方案。鉛(qian)(qian)(qian)(qian)磚容易堆疊、展開和重(zhong)(zhong)新(xin)部署，可提供程(cheng)(cheng)度的(de)(de)(de)保(bao)護(hu)。鉛(qian)(qian)(qian)(qian)磚由質的(de)(de)(de)鉛(qian)(qian)(qian)(qian)制(zhi)成，具有(you)標準的(de)(de)(de)硬度，表面平(ping)坦光滑，即使在尖銳直角的(de)(de)(de)情況下(xia)，也能(neng)(neng)實現完美平(ping)齊的(de)(de)(de)安裝。山東博創輻射(she)防(fang)護(hu)工程(cheng)(cheng)有(you)限公司
