The explosion of door and window glass happens from time to time. Once the door and window glass explodes, it is a great safety threat to pedestrians and indoor residents. What is the reason for the explosion of door and window glass? In the process of customizing doors and windows, what aspects should be paid attention to in order to avoid this risk as much as possible? The explosion of door and window glass may be a quality problem of the glass itself. There are stones, bubbles and impurities in the glass, which are the weak points of the glass and are also important factors causing the glass to break. During the glass processing process, if the glass surface has scratches, deep burst edges and other problems due to improper operation, it will also cause the glass to explode.
The shower room manufacturer reminds you that in addition to the explosion caused by the poor quality of the glass itself, accidental damage and improper installation of the door and window glass can also cause the glass to explode. If the glass is damaged during transportation, the damaged part will change the internal stress of the glass. When the glass is used for the upper wall, the internal stress of the glass will cause the explosion problem. During the installation of doors and windows, when installing the glass, if the size of the door and window glass is not appropriate, the installation will be too tight, which will also cause the internal stress of the glass to change, resulting in glass explosion.
When purchasing door and window glass, users must pay attention to the quality of door and window glass. Choose doors and windows equipped with tempered glass. Tempered glass has strong wind pressure resistance and will be blunt-angled when it bursts, which can reduce the risk of glass bursting and injuring people. Qualified tempered glass has a 3C certification mark, which requires users to identify. Tempered glass without qualified standard certification or produced through informal channels has greater safety risks. In addition, when installing door and window glass, users should also pay attention to strengthening supervision to avoid problems such as glass bursting due to installation violence or improper operation.
There are gaps in the door and window glass, causing this situation: when installing the glass, the debris in the notch is not removed in time, causing the glass to be misaligned with the notch. The gap between the glass and the glass notch is uneven, the rubber strip has poor contact with the glass and the glass groove, and it protrudes from the glass notch, and it is easy to pull the sealing strip off by hand. At the corner, the rubber strip is not broken, nor is it bonded and bonded.
There are anti-crack measures for door and window glass: install glass pads as required to support the weight of the glass and avoid deformation of the window sash. The glass installed in the vertical frame should be equipped with two load-bearing pads below, and the distance between the support point and the vertical edge of the glass should be 1/4 of the width of the glass and not less than 150 mm. The blocks should be set in other directions to fix the glass and ensure that the gap around it is uniform. The glass pad should be made of hard rubber with a hardness of 80 degrees, its width should be greater than the thickness of the supported glass, its length should not be less than 25 mm, and the thickness is generally 2 to 6 mm. Check the position of the pad before the glass is in place to prevent the pad from falling off due to collision and vibration and blocking the drainage channel. Strictly control the glass cutting size, and the difference between the glass size and the internal size of the frame fan should be equal to the thickness of the two pads.
Door and window glass gap rectification measures: Before installing the glass, carefully remove the debris in the notch, such as mortar, brick chips, wood blocks, etc. When the glass is placed, it should be carefully aligned to ensure that the gap on both sides is uniform, and it should be checked in time.
It is fixed to prevent collision displacement and stay away from the center of the notch. The rubber sealing strip cannot be stretched too tight, and the cutting length is 20-30 mm longer than the assembly length. When installing, it should be in place, with a flat surface, and tightly connected to the glass and the glass groove to make the force around the glass uniform. At the corner, the rubber strip should be broken at the bevel, and glue should be injected at the break to bond firmly. When using sealant to caulking and fix the glass, a rubber strip or rubber block should be used to squeeze the glass, leaving a gap for glue injection. The depth of glue injection should not be less than 5 mm. Before the glue solidifies, keep the glass from vibrating.
