If the door lock is zinc alloy data, its hardness and rust resistance will be very poor, that is, thick plating is also easy to fade black and rotten and blister, but its advantage is that it is easy to make messy parts, especially pressure casting. The locks of the more messy pictures seen in the market are likely to be made of zinc alloy, and the purchase should be carefully identified. Below are some methods for identifying the traditional hardware lock materials and related maintenance knowledge.
Steel, the strength is better, the cost is lower, but it is easy to rust, usually used as the internal structure of the lock, and should not be used as exterior decoration.
Aluminum or aluminum alloy, general aluminum alloy (except for aerospace) is soft and light, and the data strength is lower, but it is easy to process.
Copper is one of the most widely used lock materials. Its mechanical function is good, its corrosion resistance and processing functions are good, and its color is beautiful. Especially the handles and other locks of copper casting, the appearance is flat, the density is good, and there is no air hole. Sand eyes. It is both strong and rust-proof. It can be used for plating all kinds of surface treatments such as gold or gold. It looks magnificent and noble, and adds a lot of color to everyone's home.
From the point of view of the use, the best information should be stainless steel, especially for the appearance of materials, the more bright the light. It has good strength, strong corrosion resistance and constant color. However, there are many kinds of stainless steel, which can be mainly divided into ferrite and austenite. Ferritic stainless steel is magnetic, commonly known as stainless iron. It takes a long time and the environment is not good. It is also rust. At present, as long as 304 stainless steel is the best stainless steel information.
1. During the use of the lock, periodically (half-year or once a year) or when the key is not inserted smoothly, do not use any liquid oil such as cooking oil as a lubricant to prevent the grease from sticking to the marble spring, resulting in the lock. Can't turn but can't turn on. Usually you can use the pencil at home to apply to the key, and then insert the lock cylinder to rotate a few times to play the role of lubrication. In addition, professional lubricants, rust inhibitors, etc. for locks are also available. Some zinc alloys and copper locks, when installed on the door for a long time, will find "spots". This phenomenon is not rust, but is oxidation. If this happens, just wipe it with a surface wax. You can remove the spots.
2. In the process of using the lock, it is necessary to pay attention to the lock core not to rain into the water, because there is a small spring inside which will rust and inflexibility, which will naturally damage the normal use of the lock.
3. When the lock tongue or the insurance anti-lock lock tongue is exposed, do not force the impact to avoid damage to the lock tongue and the door frame.
4, do not use the key to open the door directly, the key to open the door lock, the lock does not return to the original directly pull the key to open the door, the lock will not be long after you will say goodbye to you.
5. The door lock has a lattice type, and the anti-use wire is inserted into the oblique lock puller which is automatically locked, and the door is pulled open, and the flower lattice type is to be maintained during use. However, you should not wipe the lock body and handle with a damp cloth to avoid rust.
6. When the door lock is not good, switch some lubricant on the oblique tongue to ensure the lubrication effect.
7. When closing the door, it is best to hold the handle, screw the tongue out or screw it into the lock body, and then let go of the door after closing the door. Do not hit the door with a bang, otherwise it will reduce the service life of the lock.
8. Normally keep the lock body clean, prevent foreign matter from entering the lock core slot, causing rolling when opening, or even the lock can not be opened.
