铝型材粉末涂装有什么作用?

来源:

1、纯度越高,耐蚀性越好,众所周知,纯铝在空气之中与氧气发作效果,在铝的表面会生产一层很薄的致密自然氧化膜,比其它金属氧化膜生成的快并且厚的多,从而阻止了空气中有害气体和水分的腐蚀,起到了维护效果.
1. The higher the purity, the better the corrosion resistance. It is well known that pure aluminium in the air and oxygen attack effect, on the surface of aluminium will produce a very thin layer of dense natural oxide film, faster and thicker than other metal oxide film, thus preventing harmful gas and water corrosion in the air, playing a maintenance effect.
2、纯铝的耐蚀性虽好,但机械强度差,这在必定程度上制约了铝的使用,因而,人们在铝中加入适量的镁、铜、锌等其他金属,制成各种类型的铝合金。
2. The corrosion resistance of pure aluminium is good, but its mechanical strength is poor, which restricts the use of aluminium to a certain extent. Therefore, people add appropriate amounts of magnesium, copper, zinc and other metals into aluminium to make various types of aluminium alloys.


铝合金的机械强度高,使铝的机械强度大大提高,使用规模大大扩大,铝合金虽机械强度高,但耐蚀性比纯铝差,因而就有或许因氧化而受腐蚀。
Aluminum alloy has high mechanical strength, which greatly improves its mechanical strength and enlarges its use. Aluminum alloy has high mechanical strength, but its corrosion resistance is worse than pure aluminum, so it may be corroded by oxidation.
这就需求进行粉末涂装对铝合金型材加以维护,铝合金以其比重小、易加工,机械强度大等特点多年来广泛使用于修建物的门窗、幕墙等产品上。,
This requires the maintenance of aluminium alloy profiles by powder coating. Aluminum alloy has been widely used in doors, windows and curtain walls of buildings for many years because of its small proportion, easy processing and high mechanical strength. ,
通过粉末涂装,铝型材具有较高的耐蚀性、颜色多样化,表面质感好等众多长处,与不同的修建外墙涂料相照应,以建造出颜色斑斓的修建。
Through powder coating, aluminium profiles have many advantages, such as high corrosion resistance, diversified colors, good surface texture and so on. It corresponds to different exterior wall coatings to build colorful construction.
