Ji'nan lead glass is a good protective material. Sometimes we have problems. Can medical lead glass block all the X rays?

　　现在在我们的生活中，x射线的应用越来越多。X射线的应用对我们来说有利也有弊，比方说我们可以通过X射线来治疗疾病，但同时我们也要做好射线防护。医用铅玻璃至少在120KV下是大于2mmpb的，也就是大于2mm铅当量，也有用厚度15mm厚的医用铅玻璃，那铅当量至少是3以上，足够防护住所有散射线。医用铅玻璃的检测报告一般是10毫米厚的铅玻璃在120KV下检测的，能够到达2mmpb，但一般医院X光室和CT 室用的是15或者许20厚的医用铅玻璃，因为能够防得一切的射线。

　　X rays are now being used more and more in our lives. The use of X rays has advantages and disadvantages for us. For example, we can treat diseases by X rays, but at the same time we should do radiation protection. Medical lead glass, at least under 120KV, is greater than 2mmpb, that is, greater than 2mm lead equivalent, but also useful thickness 15mm thick medical lead glass, that lead equivalent to at least more than 3, enough to protect all scattering lines. The test report of medical lead glass is generally 10 mm thick lead glass detection in 120KV, can reach 2mmpb, but the General Hospital of X light and CT room with 15 or a medical lead glass with 20 mm thick, because everything can prevent radiation.

铅板大幅上涨囤货的请速度—— 隔夜伦铅开于2342.5美元/吨，亚洲时段伦铅重心围绕于日均线附近维稳运行，盘中触及最低点2335.5美元/吨；欧美时段，IEA称OPEC减产执行率创纪录达90%，油价直线拉涨，支撑伦铅强势整理于日均线上方，尾盘摸高于2408美元/吨，终收于2402美元/吨，涨75美元，涨幅3.22%，成交量4105增加1325手，持仓量107736减少730手；晚间沪铅主力1703合约开于19565元/吨，最高19735元/吨，最低19495元/吨，终收于19665元/吨，涨305元，涨幅1.58%，成交量34872减少32746手，持仓量43626增加1068手。

防护铅门在医用方面的优势特点 在铅门设计过程中可根据不同射线防护门的特点进行组合选用，如利用平开射线防护门易设计气密性要求的特点、推拉射线防护门易设计屏蔽要求的特点进行组合选用，不仅可降低设计难度，而且在满足工艺要求的条件下能够最大限度地降低投资。防辐射铅门采用国标钢质骨架，以不锈钢做面板，夹衬优质射线防护铅板，结合先进的冷高压粘合工艺制作而成，配有专用的不锈钢防护门专用门轴合页，优质的五金件，进口防护门专用工程锁具。
  铅门主要用于需阻挡射线通过的进出口，常用于医院、机房和矿区中。按开启方式分为电动防辐射铅门和手动放辐射铅门; 按开启方向分为90度平开和180度直线推拉防护铅门。采用的铅板是用金属铅轧制而成的板材，具有很强的防腐蚀，耐酸耐碱，耐酸环境施工、医用防辐射，X光，CT室射线防护、加重、隔音等许多方面，而且是一种比较廉价的防辐射材料。

铅玻璃日常的使用保养工作必不可少
　　铅玻璃可用来制造防辐射玻璃、光学玻璃、电真空玻璃、低温封接玻璃、低熔玻璃、延迟线玻璃、高折光微珠玻璃及艺术容器玻璃等。但咱们若想使铅玻璃一直维持好的运用成效，对于其定期保养是无比主要的。下面，就来和大家介绍一下铅玻璃的保养知识。

　　Lead glass can be used to make anti radiation glass, optical glass, electric vacuum glass, low temperature sealing glass, low melting glass, delay line glass, high refractive micro bead glass and artistic container glass, etc.. But if we want to keep the lead glass in good service, its regular maintenance is extremely important. Next, let's introduce the maintenance of lead glass.

　　1、安装时禁止使用潮湿木材质制作窗框，因其收缩，损坏玻璃。

　　1. When installing, forbid to use damp wood material to make WINOOW frame, because of its contraction, damage glass.

　　2、铅玻璃表面不得与硬或粗糙的东西碰擦以免产生伤痕。

　　2, lead glass surface must not touch with hard or rough thing, lest produce scar.

　　3、铅玻璃的使用、贮存环境，应通风干爽，在常温下湿度不应过大。且由于含有丰富的铅和钡,铅玻璃易受酸碱的污染,不易于安装或存放在酸气或潮湿的环境中。

　　3, lead glass use, storage environment, should be ventilated and dry, at room temperature, humidity should not be too large. Because of its rich lead and barium, lead glass is susceptible to acid and alkali pollution and is not easy to install or store in acid, gas or humid environments.

　　4、铅玻璃表面，因保护不当，发生轻微的霉斑，可用无水酒精脱脂棉球抹擦即可除掉。

　　4, lead glass surface, because of improper protection, slight mildew, available anhydrous alcohol cotton ball wipe can be removed.

　　5、铅玻璃是脆性材料，比率较大移置时必须轻拿轻放;装置时必须将窗四处用铅板或者铅橡胶密封，以防四处散漏射线。

　　5, lead glass is a brittle material, the larger rate of displacement must be handled with care; when the device must be around the WINOOW using lead or lead rubber seal, to prevent the spread of leakage ray.
