Is there any change in the thermal conductivity of aluminum profile after oxidation? 5
- Of course, the heat conductivity of metals is usually worse after oxidation.Near room temperature:Thermal conductivity of alumina 10W/m = KAluminum thermal conductivity 237W/m = KBut you seem to have another problem hereThe purpose of opening the hole is to use Kong Zengda radiation area to enhance heat dissipation?This oxidation before and after oxidation play no difference.s
What tests do the aluminum profiles used in the curtain wall project do?
- Aluminum alloy material3.2.1 glass curtain wall by chemical composition corresponding to Aluminum Alloy material grades should be consistent with current national standard "the relevant provisions of the chemical composition" deformation of aluminum and Aluminum Alloy GB / T 3190, the quality of Aluminum Alloy section shall comply with the provisions of the current national standard "Aluminum Alloy architecture" GB / T 5237, section size deviation should be allowed to high grade or ultra high grade.3.2.2 Aluminum Alloy profiles by anodic oxidation, electrophoretic coating, powder coating, fluorocarbon paint spraying surface treatment, quality should be consistent with current national standard "Aluminum Alloy architecture" GB / T 5237 requirements, the thickness of surface layer should meet the requirements in table 184.108.40.206.2.3 insulated aluminum profiles produced by the strip process shall be made of PA66GF25 (polyamide 66+25 glass fiber) material and shall not be made of PVC material. A heat insulated aluminum profile produced by pouring process shall be made of PUR (polyurethane) material. The shear strength of the joint must meet the design requirements.3.2.4 and glass curtain wall matching aluminum alloy doors and windows should comply with the current national standard "aluminum alloy door", GB / T 8478 and aluminum alloy window "GB/T 8479" provisions.s
