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.

　　Lead glass is mostly used in the radiology department of hospitals to protect against radiation. For hospitals, the advent of medical lead glass is particularly important. Therefore, in ordinary times, often to lead glass cleaning, because with ordinary glass is not the same, so in cleaning can not be cleaned according to the general method of cleaning glass. Following the lead glass manufacturers to introduce the lead glass cleaning matters needing attention:

　　铅玻璃的清洗一般都会使用强酸氧化剂洗液.强酸氧化剂洗液是用重铬酸甲和浓硫酸配成.K2Cr2O7在酸性溶液中,有很强的氧化能力,对玻璃仪器又及少有侵蚀作用.所以这种洗液在铅玻璃的清洁中使用比较广泛.这类洗液在使用时要切实注意不能溅到身上,以防"烧"破衣服和损伤皮肤.洗液倒入要洗的仪器中,应使仪器周壁全浸洗后稍停一会再倒回洗液瓶.第一次用少量水冲洗刚浸洗过的仪器后,废水不要倒在水池里和下水道里,长久会腐蚀水池和下水道,应倒在废液缸中,集中处理.

　　The cleaning lead glass will generally use strong oxidant lotion. Acid oxidant lotion is with potassium dichromate and concentrated sulfuric acid with.K2Cr2O7 in acidic solution, has strong oxidation ability, less corrosion of the glass instrument again. So this kind of lotion in the lead glass cleaning is widely used. This kind of the lotion is in use to pay attention not to splash on, to prevent the "burn" rags and damage the skin. Wash lotion in the instrument, the instrument should be Biquan week after a pause for a while and then fell back washing lotion bottle. For the first time with a small amount of water washing equipment just after washing wastewater, do not pour in the pool and in the sewers, water and sewer corrosion will for a long time, should be poured in the waste water tank, centralized treatment.

　　在清洗铅玻璃时还可能用到碱性洗液.碱性洗液用于洗涤有油污物的铅玻璃,从碱洗液中捞取铅玻璃时,要戴乳胶手套,以免烧伤皮肤.In the cleaning of lead glass may also use alkaline lotion. The alkaline lotion used for washing the lead glass oil dirt, from their lead glass alkali solution, to wear latex gloves, so as not to burn the skin.
