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 应该如何预防铅中毒? 现在生活中我们会接触很多的辐射,有时铅制品是防辐射必不可少的材料,但铅对人体伤害也是比较大的,下面济南铅板厂家就向大家介绍一下在日常生活中如何预防铅中毒: Radiation now in life we will contact a lot, sometimes lead products is radiation proof essential materials, but the lead is relatively large harm to human body, the Ji'nan lead manufacturers will introduce how to prevent lead poisoning in daily life: 1、我们日常生活中很多陶瓷餐具表面的釉中都含有铅、镉等重金属,劣质产品中的含量更多.当这些重金属物质遇酸性食物时,质量差的产品就会有过量的铅、镉溶出.因此,应尽量选用表面装饰图案较少的陶瓷餐具.对不放心的产品,可用食醋浸泡几个小时,若发现颜色有明显变化说明重金属含量超标,应弃之不用. 1, in our daily life a lot of ceramic tableware surface glaze contains heavy metals such as lead and cadmium, more content of inferior products. When these heavy metals acidic food, poor quality products will be in excess of lead and cadmium dissolution. Therefore, ceramic tableware should try to use the surface decorative pattern less. Do not rest assured that the products can be soaked in vinegar for several hours, if found to have obvious color change shows that heavy metal content exceed the standard, should be discarded. 2、孩子喜欢的蜡笔、绘画用的颜料和彩漆积木等玩具中也含有铅,因此,孩子用完这些物品后应马上洗手. 2, children like crayons, paint and paint paint paint blocks and other toys also contain lead, so children should wash their hands immediately after use of these items 3、很多美白产品、染发剂中都含有铅,如果不能避免使用,就要选择知名度较高、质量相对有保证的名牌产品. 3, a lot of whitening products, hair dyes contain lead, and if you can not avoid the use of, it is necessary to select a higher reputation, quality is relatively guaranteed brand-name products 4、每天早上用自来水时,最好先将水龙头打开约1分钟后再正常使用. 4, every morning with tap water, it is best to open the tap about 1 minutes after the normal use 股领涨和摩根大通“作对”:高盛考虑率先交易比特币|xv00|8bb4195c713eb5e77b00ba15036五粮液再罚经销商:36家被减少供应因跨区域销售贵州茅台大涨近7%股价突破600元净利润同比增长成涉嫌串通垄断德三大汽车巨头总部遭欧盟搜查许家印二度成首富背后的财富逻辑贵阳废纸价格同比上涨一倍收购商感叹“一纸难求”贵州茅台大涨6%再创历史新高市值突破7500亿元许家印两
