当前铝合金建筑型材在质量上的主要问题是什么呢?最近我中心根据广东省技术监督局的计划安排,对广东省130家铝合金建筑型材生产企业的产品进行了检查,其结果是:尺寸偏差、表面质量、化学成分、力学性能、氧化膜厚度和封闭性能均符合国家标准要求的,产品质量综合判定为合格的仅将近一半;不合格的占一半以上。其中氧化膜厚度与封闭性能不符合国家标准要求的占不合格企业的90％左右。这说明在广东虽然有象华加日、兴发、开平、永利坚、省铝、大 What is the main quality problem of the current aluminum profile? Recently, according to the plan of Guangdong Bureau of Technical Supervision, our center inspected the products of 130 aluminum profiles in Guangdong Province. The result is: Deviation, surface quality, chemical composition, mechanical properties, oxide film thickness and sealing performance are in line with national standards, the comprehensive assessment of product quality as nearly half of the qualified; unqualified accounted for more than half. One of the oxide film thickness and sealing performance does not meet the national standard requirements accounted for about 90% of unqualified enterprises. This shows that in Guangdong, although there are like Canada, Hing Fat, Kaiping, Wynn Jian, provincial aluminum, large
