Insulating glass doors and windows are now more and more popular in the market. A variety of glass doors and windows are for people to see the dazzling, hollow glass doors and windows how to distinguish between true and false, it is exactly what needs to be solved. As the hollow glass doors and windows on the market are getting more and more people's attention, the fake hollow glass doors and windows that imitate the hollow glass doors and windows are followed. Let's take a look at how hollow glass doors and windows distinguish between true and false. How to distinguish true and false hollow glass doors and windows Regular hollow glass doors and windows are to seal two pieces of glass with a sealing strip, then vacuum the middle and fill with inert gas. Such a structure makes the true insulating glass door and window have good sound insulation performance. However, many inexpensive and inferior insulating glass doors and windows are only glued together with two simple glass pieces, and have not been treated as described above, so there is no such sound insulation effect that is unique to insulating glass. The first is to see if the glass is sealed. Many fake glass doors and windows are glued with black pvc foam strips and have no sealing effect. Moreover, the real hollow glass door and window is bonded with glass by 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, and there is no such equipment in the fake insulating glass. Identification of profile quality High-quality hollow glass doors and windows use high-quality profiles, such as the well-known conch profiles and green profiles in China, while the inferior hollow glass doors and windows use low-profile 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.
