1. After the rainy day, the wet glass and door and window frames should be wiped dry in time, and special attention should be paid to dry the water in the chute. The chute is used for a long time and the friction force increases, you can add a little oil or apply a layer of paraffin oil.
2. The sealing tops and glass seals are the key structures to ensure the sealing and insulation of doors and windows. If they fall off, they should be repaired and replaced in time.
Hardware maintenance is the key
1. The connection parts of the door frame frame should be checked frequently, the bolts should be tightened in time, and the damaged parts should be replaced. Locate the vulnerable parts of doors and windows such as shaft pins, wind braces, and floor springs. Check it frequently, add lubricating oil regularly to keep it clean and flexible.
2. Frequently check the joint of the door and window frame and wall. If it is loose for a long time, it is easy to deform the frame as a whole, so that the door and window cannot be closed and sealed. Therefore, the loose screws at the connection should be tightened immediately. If the screw base is loose, apply a small amount of cement to seal with epoxy super glue.
Aluminum alloy doors and windows are relatively fragile and require extra care
1. When aluminum alloy doors and windows are in use, the action should be light. Push and pull go with the flow; if you find it difficult, don't push hard, you should troubleshoot first. Dust accumulation and deformation are the main reasons for the difficulty of pushing and pulling aluminum alloy doors and windows. It is necessary to keep the door frame clean, especially the cleaning of the sliding groove. The dust accumulation of the door seal top strip in the groove can be removed with a vacuum cleaner.
2. When cleaning aluminum alloy doors and windows, people do not step on the aluminum frame, and do not pull the frame for support.
3. Aluminum alloy doors and windows can be dipped in water or neutral detergent with a soft cloth. Do not use ordinary soap and washing powder, let alone decontamination powder, toilet detergent and other strong acid-base cleaners.
