鋁型材進行粉末噴涂的原因及結果

來源:http://www.kangyanghua.com/ 發布時間:2021-08-12

鋁型材以其比重小、易加工,機械強度大等特征多年來廣泛運用于修建物的門窗、幕墻等商品上。鋁是具有銀白色光澤的比照生動的輕金屬,其耐蝕性具有以下兩個特征:
Aluminum profile has been widely used in doors, windows, curtain walls and other commodities of buildings for many years because of its small proportion, easy processing and high mechanical strength. Aluminum is a vivid light metal with silver white luster, and its corrosion resistance has the following two characteristics:
純度越高,耐蝕性越好,首要是因為純鋁在空氣傍邊與氧發作作用,在鋁表面出產一層很薄的細密天然氧化膜,比其它金屬氧化膜生成的快并且厚的多,進而阻遏了空氣中有害氣體和水分的進一步腐蝕,起到了保護作用。
The higher the purity, the better the corrosion resistance, mainly because pure aluminum reacts with oxygen in the air, and produces a thin fine and dense natural oxide film on the aluminum surface, which is much faster and thicker than other metal oxide films, thus inhibiting the further corrosion of harmful gases and moisture in the air and playing a protective role.


鋁型材的機械強度高,但耐蝕性低。純鋁的耐蝕性雖好,但機械強度差,這在一定程度上制約了鋁的運用,為此,我們在鋁中參與適當的鎂、銅、鋅等其他金屬,制成各種類型的鋁合金,使鋁的機械強度大大提高,運用范圍大大擴展,但耐蝕性比純鋁差,因而就有可以因氧化而受腐蝕。這就需要進行粉末涂裝對鋁合金型材加以保護。
Aluminum profiles have high mechanical strength but low corrosion resistance. Although pure aluminum has good corrosion resistance, it has poor mechanical strength, which restricts the application of aluminum to a certain extent. Therefore, we participate in appropriate magnesium, copper, zinc and other metals in aluminum to make various types of aluminum alloys, which greatly improves the mechanical strength and greatly expands the application range of aluminum, but the corrosion resistance is worse than pure aluminum, so it can be corroded due to oxidation. This requires powder coating to protect aluminum alloy profiles.
經過粉末涂裝的鋁型材除具有較高的耐蝕性外,還具有顏色多樣化,表面質感好等很多長處,與各種顏色的修建外墻涂料相照顧。
In addition to high corrosion resistance, powder coated aluminum profile also has many advantages, such as diversified colors and good surface texture, which are taken care of with various colors of construction exterior wall coatings.
