这些中空玻璃检测的指标你知道多少?

发布时间:2019/05/13    发布人:

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,提供优质可靠的中空玻璃已成为中空玻璃生产厂家研究的问题。每一道中空玻璃都是需经过重重测试,严格把关才能出成品。下面小编给大家总结一下中空玻璃常见的检测指标,希望对大家有所帮助!
The application of hollow glass is expanding, and people have higher and higher requirements for the quality of hollow glass. Providing high quality and reliable hollow glass has become a research issue for manufacturers of hollow glass. Every insulating glass has to undergo heavy testing and strict checks to produce the finished product. The following small edition summarizes the common detection indicators of hollow glass, hoping to be helpful to you all! 
1、初始露点:测试中空玻璃内空气是否干燥,国标规定露点等于或低于-40度为合格。
1. Initial dew point: To test whether the air in the hollow glass is dry or not, the national standard stipulates that dew point equal to or below - 40 degrees is qualified.
2、紫外线照射:测试中空玻璃密封胶是否含有影响视线的有机挥发物。中空玻璃样品经300W紫外灯连续照射168h后,在23±2℃的温度下存放一周,中空玻璃内表面不应出现雾状、油状或其他污染物。
2. Ultraviolet irradiation: test whether the hollow glass sealant contains organic volatiles that affect the sight. Hollow glass samples were irradiated by 300 W ultraviolet lamp for 168 hours and stored for one week at a temperature of 23 2 C. The inner surface of hollow glass should not be foggy, oily or other contaminants.
3、密封检验:测试中空玻璃密封胶的软硬程度,以及是否存在泄露。样品在低于环境气压10±0.5KPa的条件下保持2.5h,厚度增长偏差<15%为合格。
3. Sealing inspection: testing the degree of hardness and softness of insulating glass sealant and whether there is leakage. Samples were kept for 2.5 hours under ambient pressure of 10 +0.5 KPa, and the deviation of thickness growth < 15% was qualified.

4、高温高湿试验:主要测试密封胶的粘结力、水气透过率及分子筛的有效吸附能力是否达到标准要求。样品在高温高湿试验条件下(湿度>95%,温度在25-55℃之间有规律的变化)进行224个循环。每一个循环中空玻璃内的气体都要经过一次膨胀和收缩,这样对密封胶的粘结力就有较高的要求。另外,由于湿度较大,密封胶的水汽透过率应较低,而分子筛要有较强的吸附能力。
4. High temperature and humidity test: mainly test whether the bonding force, water vapor permeability and effective adsorption capacity of molecular sieve meet the standard requirements. Under the conditions of high temperature and high humidity (humidity > 95%, temperature changing regularly between 25-55 C), 224 cycles were carried out. The gas in each circulating hollow glass has to undergo expansion and contraction once, so the bonding strength of the sealant has a higher requirement. In addition, because of the high humidity, the water vapor permeability of sealant should be low, and molecular sieves should have strong adsorption capacity.
5、气候循环试验:这是一项耐老化试验,是对中空玻璃综合性能的考察。它模拟一年中的四季气候(冷、热、风、雨),每个循环都要经过加热、自然冷却和强制冷却三个阶段,共进行320个循环,检验中易出现问题是中空玻璃炸裂、开胶和最终露点升高。
5. Climate Cycle Test: This is an aging test and an investigation of the comprehensive properties of hollow glass. It simulates the four seasons of the year (cold, hot, wind and rain). Each cycle goes through three stages of heating, natural cooling and strong refrigeration. A total of 320 cycles are carried out. The prone problems in the test are cracking of hollow glass, gel breaking and elevation of the final dew point.
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。
With the development of glass processing industry in China and the deepening of people's understanding of the excellent properties of hollow glass, the application scope of hollow glass is expanding. Besides the wide application in glass curtain wall, automobile, aircraft and so on, hollow glass has begun to enter ordinary people's homes.
