铝合金窗防腐处理：
Anti corrosion treatment of aluminum alloy window:
(1)门窗框四周外表面的防腐处理设计有要求时，按设计要求处理。如果设计没有要求时，可涂刷防腐涂料或粘贴塑料薄膜进行保护，以免水泥砂浆直接与铝合金门窗表面接触，产生电化学反应，腐蚀铝合金门窗。(2)安装铝合金门窗时，如果采用连接铁件固定，则连接铁件，固定件等安装用金属零件最好用不锈钢件。否则必须进行防腐处理，以免产生电化学反应，腐蚀铝合金门窗。
(1) If the anti-corrosion treatment of the outer surface around the door and window frame is required in the design, it shall be treated according to the design requirements. If there is no requirement in the design, anti-corrosion coating or plastic film can be applied for protection, so as to avoid the direct contact between cement mortar and the surface of aluminum alloy doors and windows, resulting in electrochemical reaction and corrosion of aluminum alloy doors and windows. (2) When installing aluminum alloy doors and windows, if connecting iron parts are used for fixing, it is better to use stainless steel parts for connecting iron parts, fixing parts and other metal parts for installation. Otherwise, anti-corrosion treatment must be carried out to avoid electrochemical reaction and corrosion of aluminum alloy doors and windows.
