热镀锌工字钢，一种热镀锌钢材。工字钢也称钢梁，是截面为工字形的长条钢材。广泛用于各种建筑结构、桥梁、车辆、支架、机械等。镀锌工字钢由于截面尺寸均相对较高、较窄，故对截面两个主袖的惯性矩相差较大，因此，一般仅能直接用于在其腹板平面内受弯的构件或将其组成格构式受力构件。对轴心受压构件或在垂直于腹板平面还有弯曲的构件均不宜采用，这就使镀锌工字钢在应用范围上有着很大的局限。镀锌工字钢剖面图 工字钢是一种普通型型钢。型钢是一种有一定截面形状和尺寸的条型钢材。普通型钢按其断面形状又可分为工字钢、槽钢、角钢、圆钢等。今日国内钢材 市场 热镀锌工字钢的 价格 ，乌鲁木齐：4400~4850元/吨不等，无货；厦门：4700~4750元/吨；重庆：4410~4720元/吨不等；杭州：4280~4900元/不等，缺货。从这些数字中知道，热镀锌工字钢的 价格 虽然暂时稳定，但是多个钢材 市场 存在货少或缺货情况，使得这些 价格 只能仅供参考了。　热镀锌工字钢广泛应用于工业建筑和 金属 结构，如厂房、桥梁、船舶、农机车辆制造、输电铁塔，运输机械、往往配合其他镀锌型钢一起使用。

铝条之所以能做为中空玻璃的中空隔条是通过一系列金属材料相互比较最终脱颖而出的。那么到底是什么原因呢？　　 　　铝的密度很小，仅为2.7g/cm，虽然它比较软，但可制成各种铝合金，如硬铝、超硬铝、防锈铝、铸铝等。铝有较好的延展性使得它能轧制各种铝制品如铝丝铝条。铝的表面因有致密的氧化物保护膜，不易受到腐蚀。铝具有银白色光泽，而且还有防腐性能。铝对光的反射性能也很好，反射紫外线比银强，铝越纯，其反射能力越好。铝具有吸音性能，音响效果也较好，所以广播室、现代化大型建筑室内的天花板等也采用铝。耐低温，铝在温度低时，它的强度反而增加而无脆性，因此它是理想的用于低温装置材料。 　　铝的这些优点使得作为铝制品的铝条能够胜任中空铝隔条这一重任。

3003合金是以锰为主要合金元素的铝合金，对大气、淡水、海水、食品、有机酸、汽油、中性无机盐水溶液等均有良好的耐蚀性，在稀酸中的耐蚀性也很好，所以有“防锈之王“的美誉。3003合金的化学成分为：硅Si：0.60铁Fe:0.70铜Cu：0.05-0.20锰Mn：1.0-1.5锌Zn：0.10其他：单个0.05、合计0.15铝Al：余量。　　　　3003合金铝卷的强度不高，强度稍高的多用于工业纯铝，不能热处理强化，所以多采用冷加工方法来提高它的力学性能：在退火状态有很高的塑性，在半冷作硬化时塑性尚好，冷作硬化时塑性低，耐腐蚀好，焊接性良好，可切削性能不良。主要用于加工需要有良好的成形性能、高的抗蚀性、可焊接性好的零件部件。如厨具、食物和化工产品处理与储存装置，运输液体产品的槽、罐，以薄板加工的各种压力容器与管道。　　　　3003合金铝卷中空铝条是生产中空玻璃的必备材料之一，它的质量直接关系到中空玻璃的使用效果，使用年限及保温隔热功能。其主要作用是在中空玻璃中起到将两边或多片玻璃均匀隔开，有效支撑的作用。中空玻璃条是以高纯铝为原材料制作的铝制品，经几十道工艺处理后，表面平整光滑，不氧化，不腐蚀，对干燥剂不产生任何影响，有效消除雾化现象，是一种新型的环保建材产品，具有广阔的应用市场。　　　　3003合金铝卷作为河南明泰铝业的主要产品之一，所销产品表面平整光滑，防锈，防蚀亮度高;铝条表面孔透均匀，直线度好，不变形，尺寸稳定;强度高韧性好，可配合折弯设备连续折弯成任间角度的铝框。3003合金铝卷十几年工艺成熟稳定，产品畅销国内，并深得新老客户的认可和信赖。

靠前，经过互联网查找公司的名声、产品质量等信息，百度查找一下这个公司的称号、看看有没有什么负面的新闻，假如没有的话，这个公司就可以列在考虑之中　　　　第二、对考虑之中的公司供应商进行比照，比较几家厂商的实力和诚信度，有必要是有出产车间的供应商，做出的设备才够好，比方乐陵鑫烨，自己就有四条出产线，在做设备的一起，可以及时的改善和进步设备的质量。有些小供应商连设备怎样用都不知道，就搞了几台电焊机在那做设备，真的是不敢恭维.　　　　第三，眼见为实，耳听为虚.当你经过网络和电话了解的差不多的时分，就要去想收购设备的供应商那看看了，看看供应商的出产能力，还有出产规模等.　　　　第四、到了供应商，首先要看看工厂的营业执照、税务挂号等，只要正规的厂商才干出产出优质的产品，并且今后设备出了什么问题也好处理.　　　　第五、看设备，一般供应商都会有正在运用的中空铝条设备和正在加工的设备，当然，这个要有专业点的才干看的出设备的好坏.　　　　第六、谈报价签协议：在和供应商谈报价的时侯，有些中空铝条设备收购者只知道要讲廉价点的，尽管也不能只认报价，俗话说：廉价没好货，首要仍是以质量为首位，就算是买了一套在职业中较廉价的设备，到时分出产不出铝隔条，受害的仍是自己的公司。　　　　德州市德城区远大中空玻璃制品有限公司坐落山东省德州市天衢工业园，环境优美，交通便利。自古就有“九达天衢，神京门户”之称我们公司的产品销往苏、浙、沪、粤区域及全国各地。这些年，跟着公司内部的革新及业务量的灵敏增加，首要产品有：中空铝条,可折弯铝条,高频焊铝条公司在增强经济实力和革新管理体制方面现已取得了无量的效果。现已构成集研发、出产、出售、效力为一体的公司。

一、插角连接处　　　　我们常用的槽铝式的中空玻璃要求双道密封，无论哪一道的密封出现问题较终都会导致中空玻璃密封失效。内道密封用的是丁基胶，现行的国内国外的机械工艺都不能保证插角连接处的有效密封。插角连接处的问题，目前采取的都是补救措施---即由丁基胶涂布工手工填堵铝条插角的外侧。　　　　首先我们确定一个前提，就是无论哪一道的密封出现问题较终都会导致中空玻璃密封失效;然后我们对这种把丁基胶通过手工填堵铝条插角外侧的工艺做一下评价：先进生产工艺中的落后的手工环节。　　　　并且，您如果到车间去观察一下就会发现，几乎每一个插角连接处所填堵的丁基胶都不足够-即大多数的插角连接处还是单道密封，这会直接导致中空玻璃的密封失效。关于这一环节车间质管部门肯定有所重视，但为什么还会绝大多数填堵不满呢，我认为有两个因素：一是工人基本都是基本工资加计件工资，这一环节粗略一些可以节约较多的时间;二是这种工艺操作较为烦琐且做与不做或做多做少外观观察不到。　　　　折弯铝格条在四个角处是连续折弯的，插角连接处密封与直线处基本一致。较弱的部分体现在直插连接处。在北京和上海的几个玻璃深加工的大厂我观察到，直插连接处基本都是填满了的。为什么呢-因为操作简便且几乎不浪费时间。因此推断，折弯铝条即将推广开来。但是折弯铝条的价格过高，许多厂家不能接受，因此推断，新产品将随着业内的竞争发展而出现，从而使问题得到解决。　　　　以上提醒我们：注意插角连接处的密封，填堵充足。　　　　二、分子筛的吸附时间　　　　即使所有的中空玻璃材料您都用了较好的，有可能您的产品照样无法通过检测。各项材料都有其特性，例如分子筛。　　　　分之筛受检的饱吸附时间是24小时。即使再好的制作工艺，我们对分子筛使用都有一个基本的暴露时间要求：自开袋起直至您所填充的中空玻璃第二道密封胶填充完毕，时间不能超过4小时。如果您对中空玻璃有更高的要求，暴露时间可以缩短为1.5小时。暴露时间越短越好，但小于1.5小时的生产工艺较难在大批量生产中操作。　　　　有的企业对质量把握不严。05年底的一天早晨我去过一家玻璃厂的生产车间，还没到上班时间，只见一个塑料盆里的分子筛堆了半盆，大约有5公斤-如此产品能支撑得过一个夏天和一个冬天吗!。我跟他们老板把后果如实讲了，后来去的时候还是这样，再讲并没有人在意。后来我中断了和他们的业务。　　　　三、聚硫胶的固化时间　　　　一般的操作都在3-6小时之间。大家都知道，固化时间可以用A、B组分的比例来调节。这就牵扯两个问题：　　　　一是固化时间不可以任意调节，固化时间过长车间可能没有足够的空间放置;过短的话则固化速度过快，没有足够的时间来涂敷，更为严重的是会使固化后的聚硫胶的性能降低，具体时间的把握应在厂家给出的范围以内。　　　　二是由此可判断聚硫胶的部分品质-施工性能。比如中原聚硫胶，他的A、B组分的使用比例是100：7~100：14，而很多厂家给出的比例均为：10：1，大家知道，这只是一个理论数值，在实际操作中是不可能实现的，这也成为了部分厂家对质量不负责任的借口。　　　　四、中空玻璃的干燥速度和新成品的水雾　　　　上个月在一个中空玻璃厂，看到刚生产出来的中空玻璃放在了烈日下，不久就出了水雾，大家都很吃惊，猜疑中空玻璃材料的质量和制作工艺。　　　　这种现象可以用中空玻璃的干燥速度解释。大家知道，分子筛吸附水蒸气是有过程的。越好的分子筛的吸附速度越慢。分子筛只是完成了部分吸附，中空玻璃内的静态空气中还含有较多的水蒸气，因此发生了水雾现象。等待分子筛完成任务，水雾自然消失。　　　　影响中空玻璃干燥速度的几个因素有：制作车间的空气湿度、分子筛的填充比例、分子筛的吸附速度、铝条气孔的大小和密度、密封质量等。

高频焊铝隔条是将两片或多片玻璃以铝条支撑，均匀隔开并周边粘结密封，使玻璃层间形成有干燥气体空间的玻璃制品。高频焊铝隔条是一种优秀的隔热、隔音、美观适用、并可降低建筑物自重的新型建筑材料。以下就来简单介绍一下高频焊铝隔条使用细致事项。　　高频焊铝隔条的常规检查,是指对中空玻璃设备的运行情况、技术状态、工作精度、零部件磨损程度等进行测量和校验.通过检查可以及时发现隐患,有针对性地采取措施、消灭故障.根据检查的情况,制定出补缀计划,有目的地做好补缀前的预备,可以进步补缀质量,缩短补缀时间，在使用中空玻璃设备生产的过程中,经常会出现一系列的题目,因为工作人员不知如何处理,而导致故障更加糟糕,这时就是要为上机前对工作人员进行培训,可以及时的应变中空玻璃设备在生产过程的出现的题目,他们必要了解一下:　　当碰到高频焊铝隔条挤出的丁基胶,出现毛刺,不光滑.应对方法:首先要晓畅新旧机器的处理体例是不同的，对于新机器,应先观察出胶孔是否光滑,假如出胶孔粗糙,应先打磨,再试机器;旧机器,因为设备的温度传感器偶然不灵敏,表现的温度与现实的不符合,这时就必要将温度进行上调,直到出胶正常为止.当碰到丁基胶不沾铝条和玻璃时,是因为温度的影响造成,建议将温度进行上调到合适为止。　　高频焊铝隔条是常用的防锈蚀加固器材。由所以通过特别的做工技能处置，在很长时间内，高频焊铝隔条都可以坚持本身的性质和状况。不过跟着运用环境的不一样，这种加固件想要有比较高的额运用寿命，相同需求相应的技能手段作保证。通常来说中空铝条均可依据客户需求，订做各种规格，或许来图来样重新开模订做。为了使其可以具有满足长的运用寿命，会对于不一样的种类进行维护处置，首要是在产品外表做维护膜。首要是通常氧化、通常氧化＋喷砂、硬化处置、硬化处置＋喷砂。对其进行外表镀维护膜的首要意图在于为了添加外表硬度，经用，耐高温，防静电，外表润滑无毛刺等许多特色，出产作业有很大的协助，运用起来灵敏便利，配合度优。最常见的外表电镀的色彩有银色、银白色、亮银、灰色、深灰色、黑色等，或许依据客户的需求电镀各种合适的色彩。

冷轧钢板就是经过冷轧生产的钢板，俗称冷板。　　冷轧是在室温条件下将No.1钢板进一步轧薄至为目标厚度的钢板。和热轧钢板比较，冷轧钢板厚度更加精确，而且表面光滑、漂亮，同时还具有各种优越的机械性能，特别是加工性能方面。因为冷轧原卷比较脆硬，不太适合加工，所以通常情况下冷轧钢板要求经过退火、酸洗及表面平整之后才交给客户。冷轧最大厚度是0.1--8.0MM以下，如大部份工厂冷轧钢板厚度是4.5MM以下；最少厚度、宽度是根据各工厂的设备能力和市场需求而决定。 　　一般来说，冷轧钢板分为三代产品：沸腾钢为第一代，铝镇静钢为第二代，无间隙原子刚（IF钢）为第三代。   您查询的关键词是：冷轧钢板  。如果打开速度慢，可以尝试快速版；如果想保存快照，可以添加到搜藏。 "冷轧钢板""2,冷轧钢板(YB459-64)""厚度(mm)","宽度和长度 (mm)","理论重量(kg/m2)(比重:8.9)",,"厚度(mm)","宽度和长度 (mm)","理论重量(kg/m2)(比重:8.9)""0.4","600x1200 700x1430 800x1500 1000x2000","3.56",,"2.5","6000x1200 7000x1430 800x1500 1000x2000","22.25""0.45",,"4.01",,"2.75",,"24.48""0.5",,"4.45",,"3.0",,"26.70""0.6",,"5.34",,"3.5",,"31.50""0.7",,"6.23",,"4.0",,"35.60""0.8",,"7.12",,"4.5",,"40.05""0.9",,"8.01",,"5.0",,"44.50""1.0",,"8.90",,"5.5",,"48.95""1.1",,"9.79",,"6.0",,"53.40""1.2",,"10.68",,"6.5",,"57.85""1.35",,"12.02",,"7.0",,"62.30""1.5",,"13.35",,"7.5",,"66.75""1.65",,"14.60",,"8.0",,"71.20""1.8",,"16.02",,"9.0",,"80.10""2.0",,"17.80",,"10.0",,"89.00""2.25",,"20.03""冷轧铜条""2,冷轧铜条(YB459-64)""厚 度 (mm)","宽度 (mm)","长度 (mm)","理论重量(kg/m2) (比重:8.9)",,"厚 度 (mm)","宽度 (mm)","长度 (mm)","理论重量(kg/m2) (比重:8.9)""0.20","200~400","500~800","1.78",,"2.50","200~500","500~2000","22.25""0.25",,,"2.23",,"2.75",,,"24.48""0.30",,,"2.67",,"3.00",,"1000~2000","26.70""0.35",,,"3.12",,"3.50",,,"31.15""0.40","200~500","500~2000","3.56",,"4.00",,,"35.60""0.45",,,"4.01",,"4.50",,,"40.05""0.50",,,"4.45",,"5.00",,,"44.50""0.60",,,"5.34",,"5.50",,,"48.95""0.70",,,"6.23",,"6.00",,,"53.40""0.80",,,"7.12",,"6.50",,,"57.85""0.90",,,"8.01",,"7.00",,,"62.30""1.00",,,"8.90",,"8.00",,,"71.20""1.20",,,"10.68",,"9.00",,,"80.10""1.30",,,"11.57",,"10.00",,,"89.00""1.40",,,"12.46",,"11.00",,,"97.90""1.50",,,"13.35",,"12.00",,,"106.8""1.60",,,"14.69",,"13.00",,,"115.7""1.80",,,"16.02",,"14.00",,,"124.6""2.00",,,"17.80",,"15.00",,,"133.5""注 铜板和条(热轧,冷轧)的制造牌号为T2,T3,T4和TU和TUP,其化学成分应符合YB145-71规定""特殊用冷轧黄铜条""3,特殊用冷轧黄铜条(YB555-65)""厚 度 (mm)","宽度 (mm)","长度 (mm)","理论重量(kg/m2) (比重:8.8)",,"厚 度 (mm)","宽度 (mm)","长度 (mm)","理论重量(kg/m2) (比重:8.8)""0.20","200~300","500~1000","1.76",,"1.6","200~500","500~2000","14.08""0.25",,,"2.20",,"1.8",,,"15.84""0.30","200~400",,"2.64",,"2.0",,,"17.60""0.35",,,"3.08",,"2.5",,,"22.00""0.40","200~500",,"3.52",,"2.75",,,"24.20""0.45",,,"3.96",,"3.0",,,"26.40""0.50",,"500~2000","4.40",,"3.5",,,"30.80""0.55",,,"4.84",,"4.0",,,"35.20""0.60",,,"5.28",,"4.5",,,"39.60""0.70",,,"6.16",,"5.0",,,"44.00""0.80",,,"7.04",,"5.5",,,"48.40""0.90",,,"7.92",,"6.0",,,"52.80""1.0",,,"8.8",,"6.5",,,"57.20""1.2",,,"10.56",,"7.0",,,"61.60""1.3",,,"11.44",,"8.0",,,"70.40""1.4",,,"12.32",,"9.0",,,"79.20""1.5",,,"13.20",,"10.0",,,"88.00""注 (1)标记举例:用H80制成的,厚度为0.8mm,宽度为300mm,长度为1000mm的1/2硬条标记为:"" 条H80-Y20.8x300x1000YB555-65.""

近日碳酸铅价格成为了众多铅行业人士讨论的话题，可能受到铅价格的影响，铅的周边产品的价格也随之受到人们的关注。目前来说铅价格在今年将会呈现一个W字型，而W字型给予我们的信息就是铅价格在今年必定会震荡十分激烈，而这样的一种发展趋势让很多业界人士表示非常不能明白，大家纷纷表示还得持观望态度。我们平时所说的碳酸铅，它的分子式是PbCO3 ，白色或灰白色斜方结晶。密度6.6g/cm3，溶于酸和碱。不溶于水。在加热到315℃时分解。碳酸铅可由硝酸铅或醋酸铅溶液加碳酸钠或碳酸铵溶液制得。亦可由硫酸铅或氯化沿用碳酸钠处理制得。碳酸铅主要用于油漆和陶瓷工业。通过简单分析我们可以看出碳酸铅价格受铅价格的影响是非常大的，所以近期对于碳酸铅价格的动向我们也很难预料。但是我们不妨从另一个角度来看这一问题，如今市场铅价的下调，会吸引更多的消费企业进行采购，这样可以带动下游的消费，在一定的程度上会消化市场铅库存，使整个市场活跃起来，也许这对于整个市场后期铅价走势的上涨会是一个利好的消息。

现在钢材市场上出现形形的钢材，可是你又知道哪些钢材呢?关于即将触摸钢材方面的初学者来说，是不是很苦恼?现总结了钢材市场上十一大干流种类的图解与简介，期望这些图解和简介能够给初学者带来协助。 一、螺纹钢 螺纹钢是表面带肋的钢筋，也叫带肋钢筋，一般有2道纵肋和沿长度方向均匀分布的横肋。其间，螺纹钢分为I级螺纹钢(圆钢)、II级螺纹钢(HRB235)、III级螺纹钢(HRB400)、IV级螺纹钢(HRB500)。 带肋钢筋因为肋的效果，和混凝土有较大的粘结才能，因而能更好地接受外力的效果。螺纹钢用于房子、桥梁、路途等土建工程和高速公路、铁路、地道、防洪、塘坝等公用设施上。 二、线材 线材是指直径为5-22mm的热轧圆钢，因为它在市场上以盘卷方式买卖，所以又名盘条。常用的线材产品规格直径为5-13mm。线材的用处也非常的广泛，除直接效果于建筑钢筋外，还能够加工成各类专用的钢丝，如绷簧用钢丝、通讯线等，也能够加工成其他金属制品，如铆钉、铁钉等。 三、无缝钢管 无缝钢管是一种具有中空截面、周边没有接缝的圆形、方形、矩形钢材。它是用钢锭或实心管坯经穿孔制成毛管，然后通过热轧、冷轧或冷拨而近制成的。无缝钢管很多用于运送液体的管道、石油钻杆、轿车传动轴、自行架及建筑施工顶用的钢架手架等。 四、螺旋钢管 螺旋钢管是以带钢卷板为原材料,通过高温揉捏成型，然后再以主动双丝双面埋弧焊焊接而成的。它的用处也很广泛，作液体运送用在：给水、排水。作气体运送用在：煤气、蒸气、液体。作建筑结构用在：码头、路途、桥梁等。 五、镀锌钢管 镀锌钢管表面有热浸镀或电镀锌层的焊接钢管。镀锌能够延伸镀锌钢管运用寿命，添加钢管的抗腐蚀才能。广泛应用于建筑、机械、煤矿、化工、铁道车辆、轿车工业、公路、桥梁、集装箱、体育设施、石油机械、探矿机械等制作工业。 六、角钢 角钢又名角铁、是两头相互笔直成90度角形的长条钢材。角钢分等边角钢和不等边角钢两种。等边角钢的两个边宽持平。 其规格是以边宽×边宽×边厚的毫米数表明。如“∠20×20×4”，即表明边宽为 20毫米、边厚为4毫米的等边角钢。 角钢广泛地用于各种建筑结构和工程结构，如房梁、桥梁、输电塔、起重运送机械、船只、工业炉、反应塔以及容器架等。 七、槽钢 槽钢是截面为凹槽形的长条钢材。其规格以腰高(h)×腿宽(b)×腰厚(d)的毫米数表明，如100×50×8，表明腰高为100mm，腿宽为50mm，腰厚为8mm的槽钢。槽钢首要用于建筑结构、车辆制作及其它工业结构，槽钢还常常和工字钢合作运用。 八、工字钢 工字钢也叫钢梁(英文名称 IBeam)，是截面为工字形的长条钢材。工字钢的翼缘从根部向边上逐步变薄，且有必定的视点，工字钢截面受直压力好，耐拉，可是截面尺度因翼板太窄，不易抗扭。 九、H型钢 H型钢的翼缘都是等厚度的，有轧制截面，由3块板焊接组成的组合截面。因为H型钢的各个部位均以直角排布，所以它具有抗弯才能强、施工简略、节省本钱和结构重量轻等长处。 十、圆钢 圆钢是指截面为圆形的实心长条钢材。其规格以直径的毫米数表明，如“ 40”即表明直径为40毫米的圆钢。圆钢应用在许多方面，用于五金，建筑，轿车、造船、石化、机械、医药、食物、电力、动力、航天等方面。

随着国内玻璃加工行业的发展以及人们对中空玻璃的优异性能认识的不断深入，中空玻璃的应用范围在不断扩大，除在玻璃幕墙、汽车、飞机等方面得到广泛应用外，目前已开始进入寻常百姓家。这主要是由于中空玻璃的应用能改善门窗的隔热和隔音的效果，使门窗产品不仅仅能遮风挡雨，还有显著的节能效果，减少冬天取暖，夏天制冷的费用。   中空玻璃的应用在不断的扩大，人们对中空玻璃的质量要求也越来越高，如何把握市场的发展机遇，提供优质可可靠的中空玻璃已成为中空玻璃生产厂家研究关心的问题。本文将对中空玻璃基本的加工工艺过程进行简要分析。   首先介绍中空玻璃的种类及中空玻璃国家标准中的五项指标。   一、分类   目前国内市场上有两种中空玻璃：   1.槽铝式中空玻璃：此种中空玻璃80年代引入，相对成熟些，但是加工工艺较复杂。   2.铝条式中空玻璃：此种中空玻璃在国内起步较晚，但是制造工艺简单，因此应用范围广，推广很快。(现玻璃厂家生产的中空玻璃多为此种)   二、中空玻璃的国家标准中的五项指标   1.初始露点   2.密封试验   3.紫外线照射   4.高温高湿   5.气候循环试验   根据国家检测标准，如何安排我们的生产，才能达到中空玻璃的要求呢?由于两种中空玻璃在工艺流程上有很多相似之处，现就他们的共同的工艺流程进行简析。   1.玻璃切割下料   原片玻璃一般为无色浮法玻璃或其它彩色玻璃，遮阳玻璃、钢化玻璃、夹层玻璃，厚度一般为3-12MM，上述玻璃必须符合GB11614中一级品、优等品的规定，经检验合格后方可使用。玻璃切割可由手工或机器进行，但应保证合乎尺寸要求。此道工序工人在操作过程中，应随时注意玻璃表面不得有划伤，内质均匀，不得有气泡、夹渣等明显缺陷。   2.玻璃清洗干燥   玻璃清洗一定要采用机器清洗法，因为人工清洗无法保证清洗质量。清洗前须检验玻璃无划伤，为保证密封胶与玻璃的粘结性，较好使用去离子水。另外为保证水循环使用，节约水资源，可对水进行过滤，保证长期使用。清洗后的玻璃要通过光照检验，检验玻璃表面有无水珠、水渍及其它污渍，若有水珠、水渍及其它污渍，则需对机器运行速度、加热温度、风量、毛刷间隙进行调整，直到达到效果完好为止。洗完后的玻璃应在1小时之内组装成中空玻璃，另外要保证玻璃与玻璃之间不要磨擦划伤，较好有半成品玻璃储存小车，把玻璃片与片之间隔开。   3.铝条式中空玻璃的组装   (1)对环境的要求：温度应在10-30度之间   (2)相对湿度的要求：此种中空玻璃对相对湿度的要求稍低一些，正常情况即可。但应注意的是，干燥剂应选择正规厂家的合格产品，以保证干燥剂的有效使用。干燥剂开封后较好于二十四小时之内用完，因为聚硫胶的透气性较大，密封性差，因此要采用双道密封。用丁基胶作为靠前道密封，起到阻隔气体的作用。用双组份胶作为第二道密封，主要作用是粘结作用，其次才是隔气作用。实践证明，单道密封的中空玻璃寿命只有5年左右，而双道密封的中空玻璃寿命可长达20年甚至40年以上，因此，发展双道密封中空玻璃是大势所趋。   4.玻璃合片   铝条式中空玻璃，合片后铝框外边部和玻璃边部应有5-7MM的距离，用于涂第二道密封胶，双组份胶应均匀沿一侧涂布，以防止气泡，涂完后刮去玻璃表面残余。至此完成铝条式中空玻璃的加工。   5.中空玻璃的放置   中空玻璃的放置正确与否也会对中空玻璃的较终质量产生影响，无论是在生产还是在运输或在工地存放首先堆垛架的设计要求要考虑到中空玻璃的特点，堆垛架要有一定的倾斜度。但底部平面与侧部应始终保持90度，从而保证中空玻璃的两片玻璃底边能垂直地置放在堆垛架上。另外还要注意，玻璃底部不要沾上油渍，石灰及其它容剂，因为它们对中空玻璃的第二道密封胶都会产生不同程度的侵蚀作用，从而影响中空玻璃的密封性能。   为了提高中空玻璃隔音隔热的效果，现在很多生产厂家对中空玻璃采取抽掉中空玻璃内的空气而注入惰性气体，这样的工艺使得中空玻璃的性能得到了进一步的提高。   伪劣中空玻璃几个较主要的做假方法：   1.用普通玻璃替代钢化玻璃   2.用普通双面胶条替代铝合金隔条   3.铝合金隔条中没有添加干燥剂   4.仅做单道密封而不做双道密封   5.用普通密封胶替代双分子胶
