彩石金属瓦耐候性如何?

  1、彩石金属瓦表面耐候性试验是模拟夏季高温日照后冬季和夏季突然暴雨和温度的一个重复函数。金属屋面瓦表面加速气候老化试验是检验和评价屋瓦系统质量的重要试验项目。耐候性试验与实际工程有较好的相关性,能较好地反映实际的耐候性。大规模耐候性试验要求,在20个高温(70℃)-降雨(15℃)和20个加热(50℃)-冷冻(20℃)循环后,试样不得出现空鼓、脱落和裂纹。广州万铝与华南工业大学共同对具体的检测方法进行了探讨,获得了一套与国家建材检测中心类似的耐候性检测方法。我公司户外系列产品综合性能测试具有以下特点:

  The first is to simulate the weathering test of summer tiles,simulate the weathering test of summer tiles under high temperature and high temperature in winter and summer torrential rain,and accelerate the weathering test of roof tiles repeatedly;It is the most important test project test and evaluation system that affects the quality of roof tiles.The weathering test has a good correlation with the actual engineering and can reflect the actual weathering situation well.Large weathering tests require 20 times the high temperature(70 degrees Celsius)and rainfall(15 degrees Celsius),and the heating cycle(50 degrees Celsius)-freezing cycle(-20 degrees Celsius)can not appear empty,shed and crack.Guangzhou Wanade and South China University of Technology jointly discussed the specific test methods and obtained a set of testing methods similar to the National building materials testing center weather resistance.Our outdoor product internal performance test has the following characteristics:

  2、高频率:对于一个注重技术和测试的工厂,除了严格地对个别指标和实物产品进行定量检测和分析之外,还应该对每种产品进行研究和开发,调整每种配方,更换各种原材料。进行定性施工绩效和综合性能考核。


  Second,high-frequency technology and testing manufacturers,research and development,replace each product of each formula adjustment,all kinds of raw materials,in addition to the detection and analysis of individual indicators,but also physical products,construction performance and comprehensive performance testing.

  3、高时效性:商场如战场,企业为了满足市场的需求,测试的及时性往往很高,而且大多数检测机构由于制度原因,提供的服务往往很难符合企业的检测要求。


  Efficiency:Market like battlefield,in order to meet the needs of the market,the requirements of aging test are often very high,and most detection mechanisms because of the existence of the system,the services provided by enterprises are often difficult to meet the requirements of the test.


  模仿阳光:目前我国常用的抗衰老试验方法是氙电弧辐射,但氙电弧辐射和紫外光老化试验是国外广泛采用的试验方法。这两种方法基于完全不同的原理。氙灯照明试验盒模仿整个太阳光谱,包括紫外线、可见光和红外线,其目的是模拟阳光。紫外线老化试验并不试图模仿阳光,而只是模仿阳光的破坏性作用。它基于的原理是:长时间暴露在户外的持久材料是短波紫外线造成的老化最严重的损伤。


  Simulation of sunshine:the general anti-aging test method in China is high temperature arc radiation,but in foreign countries,high temperature arc radiation and ultraviolet radiation aging test is a widely used test method,these two methods are based on completely different principles.The dark light test box copies all of the solar spectrum,including ultraviolet,visible and infrared light,in order to simulate sunlight.Ultraviolet aging experiments do not attempt to decompose the sun's rays,but rather mimic the destruction of the sun's rays.Its principle is that prolonged outdoor exposure to durable materials results in the greatest damage to aging caused by short-wave ultraviolet radiation.


  经过全面的价格比较分析:我们计划采用紫外线普通烘焙灯来模拟直射阳光的状态,以保证太阳光的损伤和温度的损害接近实际情况。


  After a comprehensive cost-performance analysis:our company plans to use ultraviolet light+ordinary baking lamps to simulate direct sunlight to ensure that the damage of the sun and temperature damage are close to the actual situation.


  4、温度模拟:根据线路标准的要求,耐候性实验室的温度控制范围应达到-25~30摄氏度,但由于制冷设备的成本较高,根据冷冬热夏地区的温度变化范围,我们临时模拟了温度范围。0~70。方法如下:


  Temperature simulation:According to the requirements of the line mark,the temperature control range of the weather resistance laboratory should reach-25 degrees~30 degrees.However,due to the high cost of refrigeration equipment,and according to the temperature range of winter and summer hot and cold areas,we will conduct simulations at 0 degrees C and~70 degrees C:


  温度范围为1:0~10℃:冰冷却室内,冰水混合物喷雾冷却试验瓦。


  1-10 degrees range:mainly cold laboratory,spray cooling test tiles with ice-water mixture.


  2:10°C~50°C范围:温度控制箱主要用于调节实验室的温度,可调范围是从室温到50°C,同时使用辅助电加热装置来温暖实验室。


  Temperature ranges from 2:10 to 50 degrees Celsius.Temperature control box is mainly used for laboratory temperature regulation.The range is from room temperature to 50 degrees.The auxiliary electric heating mode is adopted for laboratory heating.


  3:50°c~70°c范围:夏季日照时间长,太阳辐射强度大。通常水平屋顶外表面空气的综合温度达到60~70°c,西墙的综合温度达到50~60°c。东墙的综合温度达到45~50°C。根据这一要求,我们使用5-10套烤灯和2套紫外线灯模拟直接阳光用于烘烤,确保实验壁的表面温度达到理想温度和足够的辐照时间。


  (3)range of 50℃:summer sunshine time is long,solar radiation intensity is high,outdoor air temperature usually reaches 60?70℃,west wall temperature reaches 50?60℃,east side temperature reaches 45?50℃,according to this requirement,the solar radiation intensity is high,the outdoor air temperature is 60℃,the west wall temperature is 50℃,the east side temperature is 45?We used 5-10 groups and 2 groups of simulated sun-baking lamps to bake.To ensure that the wall temperature reaches the ideal temperature and ensure sufficient irradiation time.


  5、附述:如上检测要领其实不代表我司产物就可以达到云云请求,但可以拿彩石金属瓦粘合剂所生产出来的彩石金属瓦和其它同类彩石瓦产品做同样的测试来区分优劣。


  These six test methods:does not mean that our products can meet such requirements,but can be used to produce stone tile metal tile adhesive and other similar stone tile products to do the same test to distinguish the pros and cons.
