It is a kind of metallic lead and rolling plate, with anti-corrosion, strong acid and alkali resistance, with the development of science and technology, is widely used as the acid environment construction, medical radiation protection, X light, many aspects of radiation protection, CT room, add sound insulation, is a relatively cheap radiation proof materials. When we use it, to make good maintenance on it, so as to prolong its service life, improve work efficiency, so how to maintain it?

　　1、防止由于人体冲击防护铅板玻璃而造成的伤害，最根本最有效的方法是避免人体对铅玻璃的冲击。在防护铅板上作出醒目的标志以表明它的存在，或使人不易靠近铅玻璃，就可以从一定程度上达列这种目的。

　　1, to prevent due to human impact protective lead glass damage, the most fundamental is the most effective method to avoid the impact of human lead glass. Make eye-catching signs in the lead on the door to indicate that it exists, or is not easy to make people close to the lead glass, it can be to some extent darie for this purpose.

　　2、在防护铅板单侧或双侧应设置护栏或摆放放花盐等装饰，并且保护正面宽度不宜太小、太窄。竖直保护应对准铅玻璃中心，水平保护应位于最高临近地板以上800至1100mm的区域内。

　　2, unilateral or bilateral protection it should be set or placed flowers such as salt barrier protection and decoration, front width is too small, too narrow. Vertical protection shall be centered on quasi lead glass. Horizontal protection shall be located within 800 to 1100mm of the floor above the floor.

　　3、保护措施应能够使人警觉有防护铅板存在，又能阻挡人体对铅玻璃猛烈的冲击，同时又起到了装饰作用，并且随着防护铅板透光尺寸逐渐变大，保护设施应能承受的集中冲击力也要随之增强。

　　3, protective measures should be able to make people aware of the protective plate can prevent the impact of human existence, to lead glass fierce, also played a decorative role, and with the door lead light enlarging, centralized protection facilities should be able to withstand the impact force also increases.

　　4、保护设施个不得存在断裂和冲击造成的弯曲，不得松动、摇摆，当不能满足要求寸应及寸更换或维修。

　　4, protection facilities shall not exist fracture and impact caused by bending, not allowed to loose, swing, when not meet the requirements, inch and inch replacement or maintenance.

　　铅板也叫铅皮指用金属铅轧制而成的板材，新铅为银白色，防护铅板时间长了会氧化为黑色，是防辐射物质中很重要的一种。由于它质量优秀，价格低廉，是中小型射线防护，墙体防护隔断的最佳板材。我们在使用时一定要对它进行维护和保养。

　　It is also called the lead sheet metal rolling and lead to a new lead, silver, lead door a long time will be oxidized to black, is a very important anti radiation. Because of its excellent quality and low price, it is the best board for middle and small size ray protection and wall protection partition. When we use it, we must maintain and maintain it.A

　 射线防护领域中使用的射线防护器材按防护对象分，有个人防护用品（如防护衣、铅玻璃、铅玻璃眼镜等）、防护装置（如防护门、防护窗等），按材料分有建材类、金属类、铅玻璃类和铅橡胶类等。

1．建材类射线防护
这类防护材料指的是各种类型的混凝土、砖、重晶石、防护涂料（填料）、成型防护板材或板块等用于射线装置机房、放射源室、辐照室、核设施等基建屏蔽防护工程的防护材料。在实际应用中，应根据射线源的种类、强度、能量和防护材料的特性来设计符合防护要求的基建屏蔽设施。

2．金属类射线防护
金属类防护器材指的是用金属材料和其它防护材料经机加工而组装成的各种射线屏蔽防护装置。例如各种规格的电动手动射线防护门、防护窗、防护屏风、防护椅、核医学科用的分药箱和储药箱、铅房、铅罐、铅砖、射线探伤铅室等。

这类防护器材多用于X射线机房、CT机房、医用加速器机房、ECT机房、射线工业探伤室、核电站等核设施。

射线防护门是较常用的一种防护器材，主要有两种开启方式，分为平开门和推拉门。就技术和工艺水平而言，防护门已经能够做得非常美观大方、结实耐用，有的厂家已将红外线、超声波或无线电传感技术用于防护门的自动控制和防碰撞，可防止意外挤伤人员事故的发生。

　　1、检查所需安装防护铅门,对探伤检查及其开关是否灵活顺畅;

　　2、把防护铅门放入到探伤防护门门洞内(必要时把探伤防护门门扇拆下),使包边位内接触面贴合墙体并垂直,必要时纠正墙体表平面;

　　3、对铰位侧框体进行垂直定位,必须做到点面在同一平面上;

　　4、铰位侧框体进行固位,拉爆(M10拉爆,∮钻头)固位或拉片固位,需牢固;

　　5、调整锁位宽体垂直位置,使探伤防护门门扇同门框之间的间隙位置达到均匀一致,并做最终的固定;

　　6、开启探伤防护门,检查开关是否灵活;

　　7、待水泥浆或发泡胶干燥后，取下防护铅门的间隙片及其垫板即可。
