随着外墙保温一体板在建筑中运用的越来越广泛,我们在选择保温一体板时要小心谨慎,这样才能避免不必要的损失。那么对于建筑外墙保温一体板在选购的时候都注意哪些问题呢?
1.认真观察饰面层
优质的从外观来看,更加的清晰,整个板材版面线条清晰明了,而且使用年限较长,使用中不会自动脱落等现象,如果是劣质的,价格吸引你,隔音效果差,线条乱七八糟,或者大小不一等问题。
2.合理判断保温材料
保温材料的好坏,首先是检查表面外观是否平整,观察泡孔是否均匀。表面平整,结皮完好,泡孔大小均匀在保温时水和湿气不容易透过材料,保温隔热密封的效果好,反正则不好。其次测试其密度和阻燃性能,有条件可以用天平秤重测出密度,看看是不是在规定范围内。阻燃性能送检是最准确的,如果没有条件,自己可以试验一下,看看在明火中材料是否燃烧,是否有刺鼻气味发出等,来判断阻燃性能。如果离火自熄灭,也可算不阻燃的材料。
 
购买外墙保温一体板时需谨慎,能否买到质量好的产品就在于你能不能按上述几条仔细辨别各种材料的好坏了。

As the external insulation board is used more and more widely in the building, we should be careful when choosing the insulation board so as to avoid unnecessary losses. So for the building exterior insulation board in the purchase of what issues?

1. Seriously observe the decorative layer
From the appearance, the quality is more clear, the entire sheet layout is clear and clear, and the service life is longer, and it will not fall off automatically during use. If it is inferior, the price attracts you, the sound insulation effect is poor, and the lines are messy. Or different sizes.
2. Reasonable judgment of thermal insulation materials
The good or bad insulation material, the first is to check whether the surface appearance is flat, observe whether the bubble holes are uniform. The surface is flat, the skin is intact, and the bubble hole size is uniform. When the heat is kept, the water and moisture are not easy to pass through the material. The effect of thermal insulation seal is good, but it is not good anyway. Secondly, the density and flame retardant performance are tested. Conditionally, the density can be remeasured with a Libra to see if it is within the specified range. The flame retardant performance inspection is the most accurate. If there are no conditions, you can test it to see whether the material is burned in the open fire, whether there is a pungent odor, etc., to judge the flame retardant performance. If the fire is self-extinguishing, it can also be considered a non-flame retardant material.
Be careful when buying a composite wall insulation board. Whether you can buy a good quality product depends on whether you can carefully identify the various materials according to the above.
