什么是防火窗型材。防火窗是指在一定时间内，连同框架能满足耐火稳定性和耐火完整性要求的窗。在防火间距不足的两建筑物外墙上，或在被防火墙分隔的空间之间，需要采光和通风时，应当安装防火窗。防火窗的主要作用就是隔离和阻止火势蔓延，此种窗多为固定窗。另一个作用呢就是屋内采光，此种窗有活动窗扇，正常情况下采光通风，发生火灾时能够起到防火分隔作用。有活动窗扇的防火窗应具有手动和自动关闭的功能。因此，选择质量优的防火窗型材是至关重要的。

What is a fireproof window profile. Fireproof window refers to a window that, together with its frame, can meet the requirements of fire stability and fire integrity within a certain period of time. When lighting and ventilation are required on the exterior walls of two buildings with insufficient fire separation distance, or between spaces separated by firewalls, fire-resistant windows should be installed. The main function of fireproof windows is to isolate and prevent the spread of fire, and these windows are mostly fixed windows. Another function is indoor lighting. This type of window has movable window sashes, which provide normal lighting and ventilation. In the event of a fire, it can play a role in fire separation. Fire resistant windows with movable sashes should have both manual and automatic closing functions. Therefore, choosing high-quality fire-resistant window profiles is crucial.

那么，如何才能选购到质量合格的防火窗型材？

So, how can I choose high-quality fire-resistant window profiles?

我们要查看防火窗型材出厂的合格证，日期规格技术条件以及企业名称。其次认真耐心查看产品的表面情况，产品颜色是不是亮丽，光泽是不是好，表面不能有明显的划伤，损伤，气泡等一系列缺点。着重注意防火窗型材的壁厚，门窗材料的产品厚度应不能小于1.0mm。接着还要着重注意防火窗型材表面的涂层厚度，阳极氧化产品的膜厚不应低于10μm，电泳涂漆产品的膜厚不低于1717μm，粉末喷涂的涂层厚度不得超出40-120μm范围，氟碳漆喷涂产品应在二涂以上，不能低于30μm。

We need to check the certificate of conformity, date, specifications, technical conditions, and company name of the fire-resistant window profiles from the factory. Secondly, carefully and patiently inspect the surface condition of the product, ensuring that the color is bright, the gloss is good, and there are no obvious scratches, damages, bubbles, or other defects on the surface. Pay special attention to the wall thickness of fireproof window profiles, and the product thickness of door and window materials should not be less than 1.0mm. Next, it is important to pay attention to the coating thickness on the surface of fire-resistant window profiles. The film thickness of anodized products should not be less than 10 μ m, the film thickness of electrophoretic coating products should not be less than 1717 μ m, the coating thickness of powder coating should not exceed the range of 40-120 μ m, and the fluorocarbon coating products should have at least two coats and not be less than 30 μ m.
