预计今日现货厂家 铅锭价格补跌200元/吨左右，市场成交趋差。沪铅早盘重心明显下行，上海市场1#铅锭主流报价17350-17500元/吨，均价17425元/吨，较前一交易日跌325元/吨。市场上金沙暂报17450元/吨左右，双燕报价17400元/吨左右；下游畏跌，接货意愿低，整体成交差。

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。

　　Smelting lead glass can not be separated from the high temperature furnace. There are many kinds of lead glass furnaces, such as burning gas or natural gas, burning oil and electric heating. There are mainly three ways of fusing

　　1、坩埚：一些铅玻璃和特殊光学玻璃是用坩埚窑来熔炼的,所说的坩埚就是耐火材料做的容器,外形有的象水壶,有的象短粗的杯子,将它们放置在高温窑炉中,烧得通红,再将原料加在里面.

　　1, lead glass and Crucible: some special optical glass is used to smelting crucible kiln, the container is made of refractory crucible, shape like kettle, some like a cup, placing them in the furnace, burned red, and then added to the raw materials inside.

　　2、玻璃液：在坩埚中原料发生各种高温化学变化,剧烈地沸腾着,放出很多气体,最后就"安静"下来了,变成了又浓又稠,软软的,就象刚刚熬好的麦芽糖一样的液体,这种液体叫做玻璃液.

　　2, glass melt in the crucible material: all kinds of high temperature chemical changes, violently boiling, emit a lot of gas, finally quiet down, turned into a thick, soft, just like cooked maltose as liquid, this liquid is called liquid glass.

　　3、实际生产：上面提到的坩埚炉容量小,供不上机械化生产的需要,所以在机械化生产中,玻璃都是在池炉中熔炼的.原料从用耐火砖砌的很大的池子的一端源源不断地加进去,熔炼好了的玻璃液从另一端源源不断地滴下来;滴到机器中去成型.池炉比坩埚可要大多了,有的池炉竞有一个小型的游泳池那样大,里面能容纳上千吨的玻璃液.玻璃液的温度很高,如果冷下来,就会凝固,所以要想将玻璃加工成一定的形状,就必须趁热制作。

　　3, the actual production capacity: crucible furnace mentioned above, not on the need for the mechanization of production, so in the mechanization production, glass melting furnace is in the pool. The raw material from one end of firebricks large pool of Everfount added, glass melting well from the other one end of Everfount trickle down; drop into the machine to molding. Furnace crucible can be bigger than, some competitive furnace has a small swimming pool as big, can accommodate thousands of tons of liquid inside the glass. The glass liquid temperature is very high, if the cold will solidify, so down to glass processing into a certain shape, it must take advantage of heat production.

　　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.
