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.

目前山东市场主力合约铅板价格已经达到17.3元/公斤，整体上比上周价格强势上行，市场涨幅在20%左右；而防辐射硫酸钡则涨幅不大且滞后，目前运行补涨行情。伴随铅板价格涨势不断扩大，期货与现货市场开始出现变化，技术上来看上海铅板今日必须创短期新高，否则或将面临回调行情。

近日山东防辐射铅板价格运行震荡行情，铅锌可谓一枝独秀。上海铅板在经历过大幅下跌之后于15000元/吨附近止跌反弹，迎来了一波像样的反弹，分析上海铅板出现这波涨势的主要原因抛开宏观消息面便是偏强的基本面支撑。铅价自2月中旬-5月中旬不断运行下跌行情，期间虽有环保检查，但下游铅板厂家库存高企，不断减产，需求难以消化铅现货供应，铅板厂家不断积累库存，期货仓单不断增加。对于铅价持偏空态度，短线关注10日均线附近支撑，触及支撑后仍将有所反弹，反弹或将不过高点再度回落，寻求下方支撑。
