Aluminum veneerWhat are the international quality testing standards for building materials? 

        关于Aluminum veneerNational standards for metal building materials, aluminum veneer quality standards have the following characteristics:

1. appearance quality

The board edge shall be cut without burr or crack. Box is not allowed to open welding and so on. The appearance should be clean, the pattern is clear, the color is basically the same, and there are no obvious scratches. The decorative surface shall be free of obvious indentation, impressions and bumps. There is no obvious color difference, garbage and garbage is not greater2. in arbitration. The appearance quality of the decorative surface should also meet the requirements of the table below. Classification requirements: 1. Roller coating shall not be damaged by leakage coating, corrugation, bubbles or penetrating coating. 2. The liquid spray coating must be free of flow traces, cracks, bubbles, wraps or other surface defects. 3. The powder spraying coating should be smooth and uniform, and no wrinkles, flow marks, bubbles, cracks, and stickiness are allowed.

        二、铝板尺寸、Aluminum veneerThe allowable deviation of dimensions shall meet the requirements of the following table. Where there are special provisions, the supplier and the demand side shall agree on the deviation. Thickness of aluminum substrate /mm, meet gb/t3880.3-2012 thickness and requirements: 1.0mm thick, width ≤ 1000mm, stone 0.07, width 1000~1350mm, stone 0.08. 1.5mm thick, ≤ 1000mm wide, 0.09 width 1000~1350mm, 0.09. 2.0mm thick, width ≤ 1000mm, stone 0.10, width 1000~1350mm, stone 0.10. 2.5mm thick, width ≤ 1000mm, 0.12 width 1000~1350mm, stone 0.10.3.0mm thick, width ≤ 1000mm, stone 0.13, width 1000~1350mm, stone 0.08.

Side length/毫米边长≤2000±2.o-1.5~0,边长&放大器;gt;2000±2.5-2.0~0.对角线/mm,长度≤2000≤2.5≤2.0,长度>2000≤3.o≤2.5。边长/毫米长度≤2000≤2.5≤1.5，长度>2000面板平坦度/(mm/m)：≤2，折角/(o)，shi 1.折叠高度/毫米，≤1.o.注意：上述规定适用于矩形的铝板。当形状是Other形状时，供给方和需求方同意。

        3. film thickness: aluminum plate thickness should meet the following requirements, surface type: film thickness requires roller coating, fluorine, secondary coating, average film thickness≥ 25, minimum local film thickness ≥ 23. Three coatings, average film thickness ≥ 32, minimum local film thickness ≥ 30. The average film thickness of polyester and acrylic is ≥ 16, and the minimum local film thickness is ≥ 14. Liquid spray, fluoride difluoride, average film thickness ≥ 30, minimum local film thickness ≥ 28. Three coatings, average film thickness ≥ 40, minimum local film thickness ≥ 38. The average film thickness of polyester and acrylic is ≥ 25, and the minimum local film thickness is ≥ 23. Powder spraying, fluorine, minimum local film thickness ≥ 30, polyester, minimum local film thickness ≥ 40. 4. welding joints, welding connection is firm, no wrong welding.

       四、阳极氧化板，Aluminum veneerNational standards, long indoor use, no discoloration, no corrosion, no oxidation, no rust. Environmental oxidation of thickened oxide films ( 10μm) national aluminum veneer standard, continuous production of anodized aluminum coil automatic production line, large output, good quality, easy to construct, high-grade oxidation and other main characteristics, strong decoration, moderate hardness, easy bending forming, continuous high-speed stamping, convenient direct processing into products, no complicated surface treatment, greatly reduce the production cycle of products, reduce the production cost of products.

        5. national standard fluorine-containing aluminum is processed from high-quality aluminum alloy materials of world-renowned companies, and then from the United StatesPpg or Akesu pvdf fluorine paint surface spraying refined. The fluorocarbon aluminum monomolecular tube is mainly composed of a panel, reinforced bone and ear. General thickness of aluminum plate: 2.0mm, 2.5mm, 3.0mm. Product color: color variety, light weight, good rigidity, high strength. The plate does not burn and has good fire resistance. Good weather resistance and UV resistance, good acid resistance, alkali resistance under normal outdoor conditions, no fading quality period of 15 years. · Good processing technology, can be processed into a plane, arc and spherical, tower and other complex shapes. * Easy to dye, easy to clean and maintain. Select color wide, excellent decorative effect. Easy to recycle, no pollution, conducive to environmental protection.

       Aluminum veneerProfiles have a highly respected position in architectural decoration materials. Kaimai Xiaobian also highly recommends that you use aluminum veneer curtain wall when decorating exterior walls. I hope today's sharing will help you!
