As a kind of adhesive, sealant plays a very important role in our daily life, especially in our home life. The application of sealant is ubiquitous, and our main analysis today is window sealant. The problem. We all know that every household will have windows, and when choosing adhesives for windows, two factors such as durability and stickiness are often taken into consideration. Otherwise, insufficient sealant adhesiveness or poor durability will affect the safety of windows. .
1. The choice of the mouth shape of the rubber strip in the ordinary casement window
Ordinary casement windows (38, 50, etc. series) are mostly sealed with two layers of inner and outer frames, which is relatively simple. Please pay attention to the following points when selecting the mouth shape of the rubber strip:
1. If the doors and windows are installed with hinges, because the window is closed along the hinge axis, the compression of the fully enclosed rubber strip should not be too large, just 1∽2mm, so as to prevent the compression from being too large. Large, it is difficult to close the side of the installation hinge, and the compression amount of the non-closed mouth type can be 2∽3mm.
2. If the doors and windows are installed by sliding bracing, because the window closing is similar to the parallel pressing process, the compression of the rubber strip can be larger, no more than 3mm, provided that the locking is not too laborious.
Second, the choice of the mouth shape of the rubber strip in the casement and lower suspension (inside opening and inverted) window
The casement and lower-hung window is a popular window type in the world. The user can handle the window by rotating the window to realize the two opening modes of the window, horizontal opening and downward hanging, as well as the closing of the window. In the suspended state, good ventilation can be achieved without occupying indoor space, and it can also prevent thieves from entering through the window.
