铝合金门窗为什么越来越少 (铝合金门窗为什么留小孔)

铝合金门窗，日渐式微，原因何在？尽管铝合金门窗曾一度流行，但如今却日渐式微，逐渐让位于其他新型门窗材料。究其原因，主要有以下几点：成本高昂铝合金门窗的成本远高于普通钢制或塑料门窗。铝合金是一种轻金属，但其强度较高，需要经过复杂加工才能成型。铝合金的防腐处理也较为昂贵，导致其整体成本居高不下。性能缺陷铝合金门窗虽然强度高，但耐候性差。铝合金容易氧化，长期暴露在户外环境中，表面容易产生锈蚀。铝合金的导热系数较高，保温隔热性能较差。美观不足铝合金门窗的外观较为单调，颜色选择有限。其表面处理工艺也比较简单，难以满足现代建筑对美观度的要求。安全隐患铝合金门窗的强度虽高，但韧性较差。在受到外力冲击时，容易发生脆断，存在安全隐患。环保问题铝合金门窗的生产过程中会产生大量废料，对环境造成污染。铝合金是一种不可降解的金属，使用寿命结束后难以回收利用。铝合金门窗为什么留小孔？铝合金门窗上留有小孔，主要是出于以下几个方面的考虑：排水门窗框内会 накопиться condensate moisture from the air, which can lead to mold growth and damage to the window. The small holes allow this moisture to escape, preventing damage.VentilationThe small holes also allow for some air ventilation, which can help prevent stuffiness and improve indoor air quality.Equalization of pressureThe small holes can help equalize the pressure between the inside and outside of the window, which can prevent the window from bulging or warping.ConclusionWhile aluminum alloy windows were once popular, their high cost, performance drawbacks, aesthetic limitations, safety concerns, and environmental impact have led them to fall out of favor. Other types of windows, such as vinyl, fiberglass, and composite windows, offer better performance, aesthetics, and value, making them the preferred choice for modern buildings.
