The application of aluminum alloy doors and windows is more and more widely. When we choose and buy doors and windows, we do not know enough about the hardware of doors and windows, and lack correct judgment and sufficient understanding. However, in doors and windows, the role of hardware and accessories is essential key components, it can be said that hardware and accessories are the most frequently used parts of doors and windows, its quality is related to the service life of doors and windows, and directly affects the comprehensive quality of doors and windows.
It can be said that the key role of the whole door and window, including the door and window hinge, is a key part.
The key to the service life of doors and windows lies in the maintenance of "hardware". The key to the maintenance of door and window hardware lies in the following four points:
1. Stainless steel handle and other stainless steel "hardware" can be wiped with brightener to add brightness.
2. The performance of hinge, hanging wheel, caster and other moving parts may be reduced due to the adhesion of dust during long-time movement. One or two drops of lubricating oil can keep it smooth every half a year.
3. Pay special attention to the direction of the handle rotation and stretching, and avoid using dead force. In particular, children should be educated not to swing on the door handle, which is easy to cause danger and may cause damage to the inner door.
4. When the lock cylinder is not flexible enough, a small amount of black powder can be scraped from the pencil lead and blown into the lock hole gently. This is because graphite is a good solid lubricant. Do not drop lubricating oil, because it will be easier to adhere to dust.
