断桥铝门窗由于产业基础好、市场前景广而备受投资商的青睐。断桥铝门窗经过多年的发展,目前已成为铝建材中技术最成熟、应用状况最好的铝门窗品种之一。 Broken bridge aluminum doors and windows are highly favored by investors due to their good industrial foundation and broad market prospects. After years of development, broken bridge aluminum doors and windows have become one of the most mature and widely used aluminum door and window varieties in aluminum building materials. 目前我国铝合金建筑隔热型材(又称断桥铝型材)主要有穿条式和浇注式两种,断桥铝填充聚氨酯的好处如下 At present, aluminum alloy Building insulation profiles (also known as bridge cutoff aluminum profiles) in China mainly have two types: threading type and pouring type. The advantages of bridge cutoff aluminum filled with polyurethane are as follows 1)防水保温一体化。 1) Integrated waterproofing and insulation. 2)高效节能,因聚氨酯具有超低温热传导率,所以耐热保温效果好。 2) Efficient and energy-saving, polyurethane has excellent heat resistance and insulation due to its ultra-low temperature thermal conductivity. 3)重量轻,大大降低了建筑载荷。 3) Lightweight, greatly reducing the building load. 4)抗老化强度的温度范围大,而且耐弱酸弱碱等化学物质的侵蚀。 4) The anti-aging strength has a wide temperature range and is resistant to the corrosion of weak acids, weak alkalis and other chemicals. 5)密封性能好,填充后无缝隙 5) Good sealing performance, no gaps after filling 6)具备一定的隔音作用 6) Has a certain sound insulation effect
