如果是劣質鋁卷會有哪些特點?

來源:http://www.cettools.cn/ 發布時間:2023-02-21

鋁卷是一種金屬板材,由鋁錠融化,加上不同合金,通過鑄軋或熱軋、冷軋、退火、橫剪等工藝加工成型。顏色多樣,外形美觀,裝飾力強,被廣泛用于外墻保溫,管道保溫和建筑裝飾。那如果是劣質鋁卷,會有哪些特點呢?鋁卷加工廠家為您分析:
Aluminum coil is a kind of metal sheet, which is melted by aluminum ingot, added with different alloys, and processed by cast-rolling or hot rolling, cold rolling, annealing, cross cutting and other processes. With various colors, beautiful appearance and strong decoration, it is widely used for external wall insulation, pipeline insulation and building decoration. What are the characteristics of inferior aluminum coils? The aluminum coil processing manufacturer analyzes for you:
特點:
characteristic:
1、化學成分不合格,在產品中摻雜大量的雜鋁、廢鋁的鋁型材成本大大減低了,但是會導致建筑鋁型材化學成分不合格,嚴重危及建筑工程穩定。
1. The chemical composition is unqualified, and the cost of aluminum profile doped with a large amount of miscellaneous aluminum and waste aluminum in the product is greatly reduced, but it will lead to unqualified chemical composition of aluminum profile for construction, seriously endangering the stability of the construction project.


2、劣質鋁卷大量減少封閉時間,減少了化學試劑損耗,成本降了,但耐腐蝕性能也大大降低了。
2. Poor quality aluminum coils greatly reduce the sealing time, reduce the loss of chemical reagents, and reduce the cost, but also greatly reduce the corrosion resistance.
3、氧化膜厚度薄。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150多元。
3. The oxide film is thin. The standard stipulates that the thickness of the oxide film of the aluminum profile for building shall not be less than 10um (micron). The thickness is not enough, and the surface of aluminum profile is easy to rust and corrosion. Some aluminum profiles without product name, factory address, production, license and certificate of conformity in the spot check have an oxide film thickness of only 2 to 4um, and some even have no oxide film. According to experts' estimation, the power consumption cost per ton of profile can be reduced by more than 150 yuan per reduction of 1 um oxide film thickness.
4、化學成分不合格。摻入大量雜鋁、廢鋁的鋁型材能大大降低成本,但會導致建筑鋁卷化學成分不合格,嚴重危及建筑工程穩定。
4. The chemical composition is unqualified. The aluminum volume mixed with a large amount of miscellaneous aluminum and waste aluminum can greatly reduce the cost, but it will lead to unqualified chemical composition of the construction aluminum coil, seriously endangering the stability of the construction project.
不合格的鋁卷,使用時會因為空氣、雨水、陽光等影響,導致鋁型材變形,甚至造成玻璃破裂、脫落等現象。
Unqualified aluminum coils will be deformed due to the influence of air, rain, sunlight, etc., and even cause the glass to break and fall off.
對于消費者而言都希望買到物美價廉的產品,這樣不但可以保證其使用效果,還可以節約成本,不過很多顧客在選購鋁卷的時候都會被銷售低價格所吸引,進而忽略產品的質量問題,這是不對的,無論什么時候都要注意產品的質量問題,這是保證產品使用效果的基礎。有關產品事項就來我們網站http://www.cettools.cn咨詢!
For consumers, they want to buy high-quality and cheap products, which can not only ensure the use effect, but also save costs. However, many customers will be attracted by the low sales price when purchasing aluminum coils, and then ignore the quality problem of products. This is wrong. We should pay attention to the quality problem of products at all times, which is the basis for ensuring the use effect of products.
