鋁合金門窗不合格怎么快速查看出來？
一、氧化膜厚度薄
Thin oxide film thickness
國家標準規定建筑鋁型材氧化膜厚度應不小于10um(微米)。厚度不夠，鋁型材表面易銹蝕、腐蝕。抽驗中一些無產名、廠址、生產許可證、合格證的鋁型材，其氧化膜厚度僅2至4um，有的甚至沒有氧化膜。據專家估算每減少1um氧化膜厚度，每噸型材可減少電耗成本一百多元。
The national standard architectural aluminum oxide film thickness should be not less than 10um (m). The thickness is not enough, the surface of aluminum profile is easy to rust and corrode. Some no name and address, production license, certificate of inspection in the aluminum oxide film, the thickness of only 2 to 4um, some even without film. According to experts estimate that each reduction in the thickness of 1um oxide film, can reduce the cost of electricity per ton of more than and 100 yuan.
二、化學成分不合格
Two, chemical composition is not qualified
摻入大量雜鋁、廢鋁的鋁型材能大大降低成本，但會導致建筑鋁型材化學成分不合格，嚴重危及建筑工程安全。
The incorporation of impurities of aluminum, aluminum scrap aluminum can greatly reduce the cost, but will lead to building aluminum unqualified chemical compositions, seriously endanger the safety of construction engineering.
三、降低型材壁厚
Three, reduce the wall thickness
90系列推拉窗型，按國家標準，鋁型材壁厚低不小于1.4mm，但是市面上很多產品的壁厚僅0.6至0.7mm。46系列地彈門型，國家標準使用的鋁型材壁厚，低不小于1.62mm，而一些產品的壁厚僅0.97至1.18mm。
90 series sliding window type, according to national standards, aluminum wall thickness of not less than 1.4mm, but most of the products on the market wall thickness of only 0.6 to 0.7mm. 46 series of door type, aluminum wall thickness using the national standard, a minimum of not less than 1.62mm, and some products only a wall thickness of 0.97 to 1.18mm.
劣質鋁型材大量減少封閉時間，減少了化學試劑損耗，成本降了，但型材耐腐蝕性能也大大降低了。
A large number of poor aluminum profiles to reduce the closing time, reducing the loss of chemical reagents, the cost down, but the profiles of corrosion resistance is also greatly reduced.
