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.

　　How to identify whether the deformation damage it?

　　1、绳股被挤出说明铅板不平衡，绳股挤出的铅板应立即报废。此种变形是一部分钢丝或钢丝束在铅板背着滑轮槽的一侧拱起形成环状，这种变形常因冲击载荷而引起，若此种变形严重时，则铅板应报废。

　　1, is that it is not out of rope balance, strand extrusion lead should be immediately scrapped. This is a part of the side deformation of steel wire or steel beam in the lead carrying the pulley groove arch ring formation, often caused by the impact load and the deformation, if the deformation is serious, then it should be scrapped.

　　2、铅板波浪形的变形是铅板的纵向轴线成螺旋线形状。这种变形不一定导致任何强度上的损失，但如变形严重即会产生跳动造成不规则的传动。时间长了会引起磨损及断丝，出现波浪形时，在铅板长度不超过25d的范围内，则铅板应报废。

　　2, lead deformation wave is a longitudinal axis in a spiral line shape plate. This deformation does not necessarily lead to any loss of strength, but if the deformation is serious, it will produce a beat, resulting in irregular transmission. A long time will cause wear and broken wire, appear wavy, in the range of lead length of not more than 25d, then it should be scrapped.

　　3、铅板直径有可能发生局部增大，并能波及相当长的一段铅板。绳径增大通常与绳芯畸变有关，其必然结果是外层绳股产生不平衡，而造成定位不正确。

　　3, it has a diameter of the possible local increases, and can spread a long lead. The increase of the rope diameter is usually related to the distortion of the rope core, and the inevitable result is that the outer rope strands are unbalanced and cause incorrect POSTTTIONing.

　　4、绳径局部严重增大的铅板应报废。扭结是由于铅板成环状在不可能绕其轴线转动的情况下被拉紧而造成的一种变形，其结果是出现捻距不均而引起格外的磨损，严重时铅板将产生扭曲，以致只留下极小一部分铅板强度。

　　4, the diameter of the rope should be scrapped the local severe increase lead. The kink is due to a deformation of a ring in the lead can not rotate around the axis of the case was caused by the tension, the result is caused by uneven pitch extraordinarily serious wear, it will be distorted, leaving only a small part of it that strength.

　　5、当外层绳股发生脱节或者变得比内部绳股长的时候就会发生这种变形，笼状畸变的铅板应立即报废。

　　5, when the outer strands occur or become disjointed than rope should occur the internal deformation, distortion of the cage it should be immediately scrapped.
