汕尾X光防護鉛磚質量廣受好評

鉛(qian)(qian)磚(zhuan)(zhuan)(zhuan)容易(yi)(yi)堆疊、展開(kai)和重新部署，可提供程度的(de)(de)(de)保護。鉛(qian)(qian)磚(zhuan)(zhuan)(zhuan)由優質(zhi)的(de)(de)(de)鉛(qian)(qian)制(zhi)成，具有(you)(you)標準(zhun)的(de)(de)(de)硬度，表(biao)面平坦光滑，即使在(zai)尖銳(rui)直角的(de)(de)(de)情(qing)況下(xia)，也(ye)能實(shi)現完(wan)美平齊的(de)(de)(de)安裝。鉛(qian)(qian)磚(zhuan)(zhuan)(zhuan)的(de)(de)(de)標準(zhun)是(shi)什么?表(biao)面:1.鉛(qian)(qian)磚(zhuan)(zhuan)(zhuan)表(biao)面不(bu)(bu)得(de)(de)有(you)(you)熔(rong)渣、顆(ke)粒氧氣物(wu)(wu)(wu)(wu)、夾雜(za)物(wu)(wu)(wu)(wu)及(ji)外來污染.2.鉛(qian)(qian)磚(zhuan)(zhuan)(zhuan)不(bu)(bu)得(de)(de)有(you)(you)冷(leng)隔不(bu)(bu)得(de)(de)有(you)(you)大于10mm的(de)(de)(de)飛邊毛刺(允許修整).標志(zhi):1.每塊鉛(qian)(qian)磚(zhuan)(zhuan)(zhuan)上(shang)映澆(jiao)鑄或(huo)打印上(shang)商(shang)標和批號(hao).2.鉛(qian)(qian)磚(zhuan)(zhuan)(zhuan)上(shang)應用不(bu)(bu)易(yi)(yi)脫落的(de)(de)(de)油漆劃(hua)出(chu)牌號(hao)標志(zhi)標志(zhi)顏色和部位應符(fu)合(he)的(de)(de)(de)規(gui)定.3.每捆鉛(qian)(qian)磚(zhuan)(zhuan)(zhuan)上(shang)應有(you)(you)醒(xing)目的(de)(de)(de)不(bu)(bu)易(yi)(yi)脫落的(de)(de)(de)標識注明生(sheng)產廠(chang)家名(ming)稱(cheng)、產品名(ming)稱(cheng)、牌號(hao)、批號(hao)和凈重。放射(she)(she)(she)性(xing)(xing)物(wu)(wu)(wu)(wu)質(zhi)發出(chu)的(de)(de)(de)射(she)(she)(she)線(xian)(xian)是(shi)我們肉眼不(bu)(bu)可見例如:α射(she)(she)(she)線(xian)(xian)、β射(she)(she)(she)線(xian)(xian)、γ射(she)(she)(she)線(xian)(xian).它們都有(you)(you)著(zhu)較(jiao)強的(de)(de)(de)穿透力普(pu)通的(de)(de)(de)磚(zhuan)(zhuan)(zhuan)不(bu)(bu)具備防護性(xing)(xing)能.而(er)鉛(qian)(qian)磚(zhuan)(zhuan)(zhuan)憑借鉛(qian)(qian)的(de)(de)(de)良(liang)好性(xing)(xing)能對諸如此類的(de)(de)(de)射(she)(she)(she)線(xian)(xian)有(you)(you)著(zhu)良(liang)好的(de)(de)(de)防護阻擋.放射(she)(she)(she)性(xing)(xing)物(wu)(wu)(wu)(wu)質(zhi)是(shi)我們真實(shi)可見的(de)(de)(de)時(shi)(shi)時(shi)(shi)發出(chu)射(she)(she)(she)線(xian)(xian).所以對于存在(zai)放射(she)(she)(she)性(xing)(xing)物(wu)(wu)(wu)(wu)質(zhi)的(de)(de)(de)場所使用鉛(qian)(qian)磚(zhuan)(zhuan)(zhuan)來建造是(shi)十分可行的(de)(de)(de).一定意義上(shang)放射(she)(she)(she)性(xing)(xing)強度隨(sui)鉛(qian)(qian)磚(zhuan)(zhuan)(zhuan)厚度按指數規(gui)律(lv)衰減同時(shi)(shi)理論上(shang)是(shi)不(bu)(bu)能完(wan)全阻隔的(de)(de)(de).。
