[China Glass Net] Soundproof glass doors and windows are more and more popular among consumers because of their sound insulation. External noise affects rest, so soundproof glass is especially important. Then how to distinguish between true and false soundproof glass doors and windows? Let's take a look at it with Xiaobian.
Regular sound-proof glass doors and windows are to seal two pieces of glass with a sealing strip, then vacuum the middle and fill with inert gas. This structure makes the sound-insulating glass doors and windows have good sound insulation. However, many cheap and inferior sound-insulating glass doors and windows are only glued together with two simple glasses. They are not treated as described above, so there is no sound insulation effect unique to the sound-insulating glass.
1, see if the glass is sealed
Many fake glass doors and windows are glued with black PVC foam strips and have no sealing effect. And the real soundproof glass doors and windows are bonded with a special sealing strip, which can guarantee the sealing. There is an aluminum spacer between the two pieces of glass, and there are many venting holes on the aluminum spacer. The desiccant is placed inside, which can absorb some moisture in the gas to prevent fogging after the glass door and window are heated. The phenomenon, while the fake soundproof glass does not have these devices.
2. Identification of profile quality
High-quality sound-insulating glass doors and windows use high-quality profiles, such as the well-known conch profiles and green profiles in China, while the inferior sound-insulating glass doors and windows use low-grade profiles, which are secondary recycling profiles. The high-quality profiles look smooth, smooth, uniform, uniform in color, free from cracks and air bubbles, and there is no breakage in the weld. The hardness is sufficient. The surface of the profile is not broken by the hammer. Inferior profiles are not uniform in color, and there are bubbles and impurities. When they are hit with a hammer, they will rupture, and even if they are pinched by hand, they will be deformed.
Summary: The above information about the authenticity of the soundproof glass doors and windows, Xiaobian introduced here, I hope that everyone in the purchase of soundproof glass doors and windows, use these identification techniques and methods, so that you will not waste energy to waste money .
