济南铝木门窗是否合格的判断方法!

如今铝合金门窗在门窗行业中已经占有主导地位,因为它坚固耐用、隔音隔热、装饰效果极佳等众多优势深受消费者喜爱,但是对于一些新手客户来说并不清楚应该如何去选择合格的铝合金门窗产品,这不,就为大家带来下文中的内容,帮助你解决难题。
Nowadays, aluminium alloy doors and windows have occupied a dominant position in the door and window industry, because of its strong durability, sound insulation, excellent decorative effect and many other advantages, which are loved by consumers. But for some novice customers, it is not clear how to choose qualified aluminium alloy doors and windows products. This will not bring you the content below to help you solve the problem.
一、氧化膜厚度薄
I. Thin oxide film thickness
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 stipulates that the oxide film thickness of building aluminium profiles should not be less than 10um (micron). Thickness is not enough, the surface of aluminium profile is easy to rust and corrode. Some aluminium profiles without production name, factory site, production license and qualification certificate were sampled and tested. The oxide film thickness was only 2 to 4 um, and some even had no oxide film. Experts estimate that every reduction of 1 um oxide film thickness can reduce the cost of power consumption by more than 100 yuan per ton of profiles.
二、化学成分不合格
2. Unqualified chemical composition
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。
Adding a large amount of miscellaneous aluminium and scrap aluminium can greatly reduce the cost, but it will lead to the unqualified chemical composition of building aluminium profiles and seriously endanger the safety of construction projects.

三、降低型材壁厚
3. Reducing the Wall Thickness of Profiles
90系列推拉窗型,按标准,铝型材壁厚低不小于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,标准使用的铝型材壁厚,低不小于1.62mm,而一些产品的壁厚仅0.97至1.18mm。
According to the national standard, the wall thickness of 90 series push-pull window is not less than 1.4 mm, but the wall thickness of many products on the market is only 0.6 to 0.7 mm. The wall thickness of aluminium profiles used in the national standard is not less than 1.62 mm, while the wall thickness of some products is only 0.97 to 1.18 mm.
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。
Low quality aluminium profiles greatly reduce the sealing time, chemical reagent loss and cost, but the corrosion resistance of profiles is also greatly reduced.
以上就是为大家列出的三条劣质铝合金的标准,供广大消费者参考,这样你还在担心购买铝合金门窗的时候买到不合格的产品吗?
These are the three standards of inferior aluminium alloy listed for the reference of consumers, so you are still worried about buying unqualified products when buying aluminium alloy doors and windows?
