Aluminum alloy doors and windows sealed plastic strip categories and performance
[China Aluminum Network] aluminum alloy door and window sealant strips in all types of doors and windows to play a waterproof, sealed, energy saving, noise, dust and other effects. Usually has good tensile strength, good elasticity. There is also better weatherability and aging. In order to ensure the tightness of the sealing strip and the profile, the sectional structure of the sealing strip must match the profile of the steel door and window profile.
Aluminum alloy door and window seals are divided into glass sealant and top two.
Aluminum alloy door and window profiles often have sealant notches and beads. Through the fan and the frame of the rubber strip to make the glass and the frame fan closer, thus ensuring the airtightness of the doors and windows. The installation of sealant strips also requires that the contact area should be flat, not curled or stretched, and the joint should be less than 1mm. At the same time, the model should be matched with the slot, door and window reserved space, too large and small will have corresponding problems. Of course, the sealant should be non-toxic. Odorless and environmentally friendly sealant.
The tops are equipped with push-pull fans, which mainly play a role in windproof and dustproof. The same specifications must also be matched. If the size of the top is too large or the pile is too high, not only the assembly is difficult, but also the resistance to movement of the door and window is increased. In particular, the initial resistance to opening and the resistance to closing are large. If the specification is too small, the height of the vertical strips is not easy to escape from the tank and the sealing performance of the (door) window is greatly reduced. Tops are divided into normal tops and siliconized tops. The appearance of the top quality wool is straight and the bottom plate and the pilo are smooth. No bending, no dots on the bottom plate. bubble. The plywood is firmly bonded to the base plate and has a uniform density and is less prone to hair loss.
The airtightness and watertightness of doors and windows, and the sealing strips are the best. But when it comes to sound insulation, although the sealant has a certain role, the highlight is on the glass. The traditional single-layer glass has limited sound insulation. The appearance of hollow glass and hollow laminated glass has greatly improved the soundproof effect of windows.
