Aluminum extrusion ratio calculation formula is used for expressing aluminum alloy deformation size parameters in the production of aluminum extrusion profile, namely extrusion coefficient. That is products’ total cross sectional area before extrusion (unit mm2) divides products’ total cross sectional area after extrusion (unit mm2). Therefore, extrusion ratio and the deformation degree have the following … Continued
Here are some tips for you to discern the quality of the architectural aluminum profile. 1. Check the factory quality certificate, pay attention to the date of production, specifications, technical conditions, enterprise name, and the production license number. 2. It is important to note that the wall thickness of the aluminum profile product. The thickness … Continued
There are plenty of factors of low zinc coating binding force, but the following five kinds of situations are relatively seen by people. (1) Add too much additive. The brightness of zincate galvanized layer is less than potassium chloride galvanized layer. Some people think that adding more brightener can enhance brightness. As a result, this … Continued
The surface treatment of aluminum ceiling is coating, roller coating, and anodic oxidation. The several technical methods and advantages of the implementation are not identical respectively. Coating is kinds of physical technology, forming by pressing a layer of film and a layer of aluminum plate after high temperature and high pressure. Roller coating is to … Continued
High alumina brick is classified according to the content of Al2O3. It is often used by 48%, 55%, 60%, 65%, 60%, and 75% content. Of course, higher levels content belongs to corundum brick. According to the content, materials’ content is below 55 percent content calls clay brick. It is a kind of neutral refractory, made … Continued

Windows and doors, curtain wall energy saving methods: Aluminum profiles in windows and curtain wall systems, not only plays a supporting role in the keel, but also have a greater impact on energy savings. Typically, the aluminum profile section area smaller than that of glass, therefore, the thermal influence on the energy saving effect is … Continued
Orange peel aluminum surface defect characteristics reflect: Sometimes orange peel surface shape after stretching aluminum wrinkles, this is actually generated by the aluminum metal surface when the stress is greater than the base metal surface metal fragments (grain crushing), if it continues afterburner, stress will be from the table and Lane until the matrix fracture. … Continued
