醫用(yong)鉛(qian)板(ban)(ban)是機械設備行業(ye)常見(jian)的(de)(de)板(ban)(ban)才之一(yi)，指用(yong)金屬(shu)材料(liao)(liao)(liao)鉛(qian)冷軋而成(cheng)的(de)(de)板(ban)(ban)才，具備較強的(de)(de)耐腐蝕，耐酸性(xing)自然(ran)環境(jing)工(gong)(gong)程施工(gong)(gong)、醫療(liao)器材防電(dian)磁輻射(she)(she)(she)，X光，CT室x射(she)(she)(she)線(xian)防護(hu)(hu)、加劇、隔音降(jiang)噪等很多(duo)層面，并且(qie)是一(yi)種較為便(bian)宜的(de)(de)防輻射(she)(she)(she)材料(liao)(liao)(liao)。可是鉛(qian)這(zhe)類(lei)金屬(shu)材料(liao)(liao)(liao)有(you)害，因而怎樣(yang)能既運用(yong)這(zhe)類(lei)原(yuan)(yuan)材料(liao)(liao)(liao)的(de)(de)有(you)效(xiao)性(xing)，有(you)盡量減少其傷害。醫用(yong)鉛(qian)板(ban)(ban)是一(yi)種常見(jian)來(lai)防護(hu)(hu)射(she)(she)(she)線(xian)的(de)(de)物件，假如醫用(yong)鉛(qian)板(ban)(ban)的(de)(de)品質不(bu)過關，會對(dui)觸碰(peng)射(she)(she)(she)線(xian)的(de)(de)人很不(bu)。目(mu)前的(de)(de)一(yi)些醫用(yong)鉛(qian)板(ban)(ban)經(jing)常會發覺(jue)泄露(lu)射(she)(she)(she)線(xian)的(de)(de)事兒。執行例:1.******提前準(zhun)備原(yuan)(yuan)材料(liao)(liao)(liao):鉛(qian)粉30-40kg、聚乙烯蠟l-3kg、納米技術(shu)二(er)(er)氧(yang)化3_9kg、膠原(yuan)(yuan)蛋(dan)白(bai)水解(jie)反(fan)(fan)應物0.5-0.9kg，丙(bing)二(er)(er)醇(chun)4_9kg和靛(dian)藍2_9kg。2.鉛(qian)粉30-40kg、聚乙烯蠟l_3kg、納米技術(shu)二(er)(er)氧(yang)化3_9kg、膠原(yuan)(yuan)蛋(dan)白(bai)水解(jie)反(fan)(fan)應物0.5-0.9kg，丙(bing)二(er)(er)醇(chun)4-9kg和靛(dian)藍2-9kg混和起來(lai)，隨后放到(dao)反(fan)(fan)應罐(guan)里(li)反(fan)(fan)映(ying)29-45分鐘，反(fan)(fan)映(ying)溫度(du)100-234攝氏，工(gong)(gong)作壓力1-2Kpa，反(fan)(fan)映(ying)全過程到(dao)一(yi)半時間情況下，添加塑(su)化劑0.5-0.9kg。3.取(qu)下之后的(de)(de)原(yuan)(yuan)材料(liao)(liao)(liao)歷經(jing)鑄造，拉(la)撥4-7次，隨后擠扁(bian)變成(cheng)板(ban)(ban)塊(kuai)。4.變成(cheng)板(ban)(ban)塊(kuai)之后延(yan)伸和鋪平。5.其優勢(shi)取(qu)決于:本方式制做的(de)(de)醫用(yong)鉛(qian)板(ban)(ban)針(zhen)對(dui)射(she)(she)(she)線(xian)的(de)(de)防護(hu)(hu)強，針(zhen)對(dui)身體維護(hu)(hu)更(geng)為有(you)益。便(bian)捷大(da)伙(huo)兒應用(yong)。

射(she)線(xian)(xian)防護(hu)(hu)鉛(qian)(qian)板原理鉛(qian)(qian)pbO的(de)比(bi)重大(da)，密度高（11.34g/cm3），具有阻止X射(she)線(xian)(xian)及(ji)其他射(she)線(xian)(xian)穿透(tou)的(de)作用，因(yin)此常(chang)用于射(she)線(xian)(xian)防護(hu)(hu)工程施(shi)工。用于射(she)線(xian)(xian)防護(hu)(hu)的(de)鉛(qian)(qian)板，一(yi)般(ban)在1-10mm以(yi)內，平常(chang)所講鉛(qian)(qian)當量或(huo)者防護(hu)(hu)當量也(ye)指(zhi)的(de)是相當于1mm厚(hou)的(de)鉛(qian)(qian)板所能達到(dao)的(de)防護(hu)(hu)射(she)線(xian)(xian)效果。與(yu)普(pu)通的(de)鉛(qian)(qian)板不(bu)(bu)同(tong)，用于射(she)線(xian)(xian)防護(hu)(hu)的(de)鉛(qian)(qian)板要求厚(hou)度要均勻，無氧化夾雜物和氣泡，若厚(hou)度不(bu)(bu)均勻或(huo)者鉛(qian)(qian)板中含有氣泡等，就(jiu)會(hui)大(da)大(da)降低其阻擋(dang)x射(she)線(xian)(xian)穿透(tou)的(de)效果。我(wo)們國內生產的(de)鉛(qian)(qian)板一(yi)般(ban)不(bu)(bu)會(hui)超(chao)過1.5m寬，因(yin)為(wei)比(bi)較重，所以(yi)長度不(bu)(bu)宜超(chao)過5M否(fou)則運輸較為(wei)困難。
