1、純度越高，耐蝕性越好，眾所周知，純鋁在空氣之中與氧氣發生作用，在鋁的表面會生產一層很薄的致密自然氧化膜，比其它金屬氧化膜生成的快而且厚的多，從而阻止了空氣中有害氣體和水分的腐蝕，起到了保護作用.
1, the purity is higher, its corrosion resistance is better, as everyone knows, pure aluminum react with oxygen in the air, can produce dense natural oxide film with a thin layer of the aluminum surface, than other metal oxide film generated fast and thick, so as to prevent the corrosion of harmful gas and moisture in the air, to protective effect.
2、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應用，因此，人們在鋁中加入適量的鎂、銅、鋅等其他金屬，制成各種類型的鋁合金，鋁合金的機械強度高，使鋁的機械強度大大提高，應用范圍大大擴大，鋁合金雖機械強度高，但耐蝕性比純鋁差，因此就有可能因氧化而受腐蝕。這就需要進行粉末涂裝對鋁合金型材加以保護，鋁合金以其比重小、易加工，機械強度大等特點多年來廣泛應用于建筑物的門窗、幕墻等產品上。，
2, the corrosion resistance of pure aluminum is good, but the poor mechanical strength, which restrict the application of aluminum, to a certain extent, therefore, the people joined the amount of magnesium, copper, zinc and other metals in aluminum is made of aluminum alloy, various types of aluminum alloy, the mechanical strength is high, the mechanical strength of aluminum greatly improve, application scope greatly expanded, aluminum alloy is of high mechanical strength, corrosion resistance than the pure aluminum is poor, so it is possible and subject to corrosion by oxidation. This requires a powder coating to protect aluminum alloy profiles, aluminum alloy with its small weight, easy processing, high mechanical strength over the years are widely used in the building doors and windows, curtain wall products. ,
經過濟南氟碳噴涂 http://www.mediafiresite.com/ ，鋁型材具有較高的耐蝕性、色彩多樣化，表面質感好等眾多優點，與不同的建筑外墻涂料相呼應，以建造出色彩斑斕的建筑。
After the Ji'nan fluorocarbon coating, corrosion resistance, color aluminum profiles with higher diversification, the surface texture of a good many advantages, echoes with the different building external wall coating, in order to build a colorful building.
