防火窗是建筑物中必不可少的部件，我们安装它的目的主要是火灾发生的时候能做到隔离火源并阻止火势蔓延。为了保证其使用效果以及寿命，我们需要定期进行保养。在保养时，我们要：

Fireproof windows are essential components in buildings, and our main purpose of installing them is to isolate the fire source and prevent the spread of fire in the event of a fire. To ensure its effectiveness and lifespan, we need to perform regular maintenance. During maintenance, we need to:

1. 防尘，要每天或每周清理铝合金防火窗表面上的灰尘，以防止灰尘积累影响窗户的开关和密封性能。但是，用湿抹布擦拭其表面时，不要长时间放置。因为长时间放置会侵害表面，造成材料变色或脱离。也不要用硬币或其他尖锐物品摩擦，这样很容易划伤表面，污迹太重时，可以使用清洗剂、专用清洗剂等去除污迹。然后后用清水擦拭，擦干。

1. Dust prevention: Clean the surface of aluminum alloy fireproof windows daily or weekly to prevent dust accumulation from affecting the opening and sealing performance of the windows. However, when wiping its surface with a damp cloth, do not leave it for a long time. Because prolonged storage can damage the surface, causing the material to discolor or detach. Do not rub with coins or other sharp objects, as it can easily scratch the surface. If the stains are too heavy, you can use cleaning agents, specialized cleaning agents, etc. to remove them. Then wipe with clean water and wipe dry.

2. 润滑，钢制防火窗的铰链等部位需要定期（3个月或半年）加注润滑油，以保证窗户可以顺畅开启和关闭。

2. Lubrication: The hinges and other parts of steel fireproof windows need to be regularly (3 months or 6 months) lubricated to ensure smooth opening and closing of the windows.

3. 窗缝封条，如果发现窗缝封条出现老化或破损等现象，应该及时更换，才能保证门窗的密合性。

3. If the window seal is found to be aging or damaged, it should be replaced in a timely manner to ensure the tightness of doors and windows.

4. 对钥匙孔进行保养，在使用过程中，经常用的锁芯容易出现硬塞、转不动或失去弹性等情况，应在钥匙孔内加入适量的润滑油保证锁芯能够正常使用。

4. Maintain the keyhole. During use, frequently used lock cores are prone to hard plugs, inability to rotate, or loss of elasticity. An appropriate amount of lubricating oil should be added to the keyhole to ensure that the lock core can be used normally.
