If the hardware fittings are the joints of doors and windows, then the sealing material is the warm clothes for doors and windows. If it is cold, you should add clothes and quilt. Otherwise, you will suffer from cold and be ill in bed if you have a cold.
If the sealing material of a door and window is not selected correctly and the sealing work is not done well, then the door and window can not play its original function. Especially for the current bridge broken aluminum alloy doors and windows, if you want to have good sound insulation and heat insulation performance, you must do the sealing work well first, otherwise the water mist will enter the hollow layer glass, which will make a layer of water mist in the middle of the window glass Line of sight.
The sealing materials for aluminum alloy doors and windows can be divided into sealing materials for inlaying glass and sealing materials for sealing between frames and fans according to their uses; and they can be divided into sealant strips, sealing wool strips and sealants according to the materials.
Sealant is mainly used for inlaying glass, sealing wool is mainly used for sealing between aluminum alloy sliding doors and window frames. Sealant strip plays a role in fixing glass, buffering vibration and blocking water and air flow in the use of doors and windows. Thermoplastic EPDM sealing strip has been widely used in building doors and windows in recent years. Its performance and service life are comparable to those of fluidized EPDM rubber sealing strip, and the processing energy consumption is relatively low. It is important that this sealant does not contain heavy metals and can be recycled after being discarded, which conforms to the development concept of green and sustainable development.
In order to keep the door and window surface dry, it is recommended to apply the glue on both sides of the door and window to keep the door and window dry by 3 times of air drying.
The installation and use of doors and windows require the use of sealing materials to achieve the closure and sealing between aluminum profiles and glass, between fans and frames. Therefore, the sealing material of doors and windows is a functional accessory that can not be ignored in the process of door and window installation, and its performance and service life also need to be paid attention to.
