一、氧化膜厚度薄
Thin oxide film thickness
国家标准规定建筑铝型材氧化膜厚度应不小于10um(微米)。厚度不够,铝型材表面易锈蚀、腐蚀。抽验中一些无产名、厂址、生产许可证、合格证的铝型材,其氧化膜厚度仅2至4um,有的甚至没有氧化膜。据专家估算每减少1um氧化膜厚度,每吨型材可减少电耗成本一百多元。
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、化学成分不合格
Two, chemical composition is not qualified
掺入大量杂铝、废铝的铝型材能大大降低成本,但会导致建筑铝型材化学成分不合格,严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,按国家标准,铝型材壁厚更低不小于1.4mm,但是市面上很多产品的壁厚仅0.6至0.7mm。46系列地弹门型,国家标准使用的铝型材壁厚,更低不小于1.62mm,而一些产品的壁厚仅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.
劣质铝型材大量减少封闭时间,减少了化学试剂损耗,成本降了,但型材耐腐蚀性能也大大降低了。
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.
