Aluminum alloy door and window sealing strip plays a role of waterproof, sealing, energy saving, sound insulation and dustproof in various types of doors and windows. Usually have good tensile strength, good elasticity. There are better weather resistance, expansion of aging. In order to ensure the fastening of the sealing strip and the profile, the cross-sectional structure size of the sealing strip must be matched with the plastic steel door and window profile.
Aluminum alloy door and window sealing strip is divided into two kinds of glass sealing strip and wool strip.
Aluminum alloy door and window profiles usually have notches and bindings of sealing strips. The glass and the frame fan are more closely matched by the fan and the rubber strip of the frame, thus ensuring the air tightness of the doors and windows. There are also requirements for the installation of sealant strips. The contact parts shall be smooth, curled or stretched. The joint shall be less than 1MM. At the same time, the model shall match the reserved gap between notches and doors and windows. If it is too large or too small, there will be corresponding problems. Of course, the sealing strip should be non-toxic. Tasteless environmental protection special sealing strip.
The wool strips are mostly installed on push-pull fans, which mainly play a role in preventing wind and dust. The same specifications should also be matched. If the top specifications are too large or the bristles are too high, it will not only be difficult to assemble, but also increase the movement resistance of doors and windows, especially the initial resistance of opening and the resistance of closing. If the specification is too small, the height of the vertical wool strip is not enough to easily come out of the groove, which greatly reduces the sealing performance of the (door) window. The wool top is divided into ordinary wool top and siliconized wool top. The appearance of qualified wool top is flat and straight surface, smooth bottom plate and vertical hair. No bending, no pitting on the bottom plate. Bubbles. The erection hairs are firmly bonded to the bottom plate, with uniform density and not easy to shed hairs.
The air tightness and water tightness of doors and windows, and the sealing rubber strip are extremely important. But when it comes to sound insulation, although the sealing strip has a certain effect, the highlight falls on the glass. Traditional single-layer glass has limited sound insulation. The emergence of hollow glass and hollow laminated glass has greatly improved the sound insulation effect of windows.
