铝板是建筑装饰行业广泛使用的产品。它具有良好的美观性和耐腐蚀性。为了保证其良好的性能,在加工过程中需要对其进行表面处理。下面铝板厂家小编为大家介绍几种表面处理方法。
Aluminum plate is widely used in building decoration industry. It has good aesthetics and corrosion resistance. In order to ensure its good performance, it is necessary to carry out surface treatment in the processing process. The following aluminum plate manufacturers will introduce several surface treatment methods.
铝板幕墙的加工是由两层0.5mm厚的纯铝板夹在PVC或PEC塑料之间,经滚压热合而成。铝合金单板——2~3mm铝合金板。颜色方面,灰色的选择较多。具体颜色需要大订单量加工。色彩均匀性好,方向性高。
The aluminum curtain wall is made of two layers of 0.5mm thick pure aluminum plates sandwiched between PVC or PEC plastics and rolled and heat sealed. Aluminum alloy veneer - 2 ~ 3mm aluminum alloy plate. In terms of color, gray has more choices. Specific colors need to be processed in large quantities. Good color uniformity and high directivity.
铝板幕墙表面经过镀铬等前处理后进行氟碳喷涂处理。氟碳涂料采用聚偏二氟乙烯树脂加面漆和清漆。铝板厂家认为这样处理的氟碳涂层具有良好的耐腐蚀性和耐候性,能抵抗酸雨、盐雾和各种空气污染物,具有良好的耐寒耐热性,能抵抗强烈的紫外线照射,长期保持不褪色和非粉化。
The surface of aluminum curtain wall shall be subject to fluorocarbon spraying after chrome plating and other pretreatment. Fluorocarbon coating is made of polyvinylidene fluoride resin plus top coat and varnish. Aluminum plate manufacturers believe that the fluorocarbon coating treated in this way has good corrosion resistance and weather resistance, can resist acid rain, salt fog and various air pollutants, has good cold and heat resistance, can resist strong ultraviolet radiation, and will not fade or powdered for a long time.
加工主要有加强筋、角码和表面现象喷涂。角码可以直接从面板上折弯冲压成型,也可以在面板的小边上铆接角码形成。加强筋与板后的电焊螺钉连接(螺钉直接焊接在板的背面),使其成为一个坚固的整体。
Processing mainly includes reinforcement, corner code and surface phenomenon spraying. The corner code can be bent and stamped directly from the panel, or it can be formed by riveting the corner code on the small edge of the panel. The reinforcing rib is connected with the electric welding screw behind the plate (the screw is directly welded on the back of the plate), making it a solid whole.

幕墙铝板的表面处理可分为两种方法,一种是阳极氧化,另一种是静电喷涂。阳极氧化膜一般大于12,只有青铜色和白色两种颜色,颜色单调。因为铝板不是由一个批号组成的,并且在化学成分上有很小的差异,并且在氧化过程中诸如电解槽液体的电流密度等因素不能完全相同,所以氧化后的颜色有所不同,这在单个板中可能不明显,但是如果它们都排列在一起,则非常明显。因此,不得将阳极氧化用于铝板幕墙的铝板表面处理。
The surface treatment of curtain wall aluminum plate can be divided into two methods: anodic oxidation and electrostatic spraying. The anodic oxide film is generally larger than 12, with only two colors, bronze and white, and the color is monotonous. Because the aluminum plate is not composed of one batch number, and there is little difference in chemical composition, and factors such as the current density of the electrolyzer liquid cannot be the same during the oxidation process, the color after oxidation may be different, which may not be obvious in a single plate, but it is very obvious if they are all arranged together. Therefore, anodic oxidation shall not be used for the surface treatment of aluminum curtain wall.
幕墙铝板表面处理的另一种方法是静电喷涂。喷涂分为粉末喷涂和液体喷涂。粉末喷涂材料主要包括聚氨酯、聚膨胀树脂、环氧树脂等具有高保色性颜料的原料,可获得几十种不同颜色的喷涂粉末。喷涂粉末耐碰撞、耐磨、耐稀酸和砂浆。
Another method for surface treatment of curtain wall aluminum plate is electrostatic spraying. Spraying is divided into powder spraying and liquid spraying. Powder spraying materials mainly include polyurethane, polyexpandable resin, epoxy resin and other raw materials with high color retention pigments. Dozens of different colors of spraying powders can be obtained. Spray powder impact resistant, wear-resistant, dilute acid resistant and mortar.
