選擇好鋁材你做好這些了嗎?

來源:http://www.cettools.cn/ 發布時間:2018-11-12

1、看表面和斷面。如果表面和斷面光亮,就表明鋁材的合金成分高,比較純。如果是斷面發黑,或者說表面色澤不光亮,就表明這種鋁材是用回收料做的。
1, look at the surface and section. If the surface and section are bright, it indicates that aluminum alloy has high composition and purity. If the section is black, or the surface is not bright, it shows that this kind of aluminium material is made of recycled materials.
2、看強度。用兩種鋁材,好料和次料碰撞,好的料不會有太大的磕跡,壞的料就會沉下去一個溝槽。
2, look at the intensity. With two kinds of aluminium material, good material and secondary material collision, good material will not have too much scratch, bad material will sink a groove.
3、看報價。材質不一樣,表面處理不一樣,鋁材的壁厚不一樣,報價就不一樣,差很遠。如果報價低的,多半是次料回收,壁厚太薄,同樣1米,人家重4KG的,它才兩公斤多,人家壁厚是5MM的,它才1.2MM。
3, look at the offer. Different materials, different surface treatment, different wall thickness of aluminium, different quotations, far from. If the quotation is low, most of them are recycled secondary materials, the wall thickness is too thin, the same 1 meter, people weigh 4KG, it's only two kilograms, people's wall thickness is 5MM, it's only 1.2MM.

How to make doors and windows for doors and windows?
做門窗所用的鋁材要挑性價比高的,建議如下:

鋁板生產廠家
The aluminum materials for doors and windows should be selected with high cost performance.
1、窗輪要好,壓玻璃的膠條要耐舊耐腐蝕;
1, the window wheel is better, and the glass strip should be resistant to old corrosion resistance.
2、門窗密封性能要好;
2, doors and windows sealing performance is better.
3、紗頁要與材料配套,紗網要不生銹的且厚度及密度要好;
3, the yarn pages should be matched with the materials, and the gauze is not rusty, and the thickness and density are better.
4、性價比要高,型材的表面處理層要是電泳的,且電泳層要厚;
4, high cost performance. The surface treatment layer of the profiles should be electrophoretic and the electrophoresis layer should be thick.
5、安裝框架要打到水平線。
5, the installation frame must be horizontal.
