The hottest tempered glass is not the thicker the

Toughened glass is not the thicker the better. Bubbles in the glass are a quality problem.

yesterday, a breakthrough was made in the production and utilization of fully biodegradable mulch film. Mr. Lin, a consumer, told this newspaper that he had a worry: he bought a whole bathroom of toughened glass. After using it for less than half a year, the bathroom door suddenly broke. Subsequently, this newspaper interviewed director Nie of the interior decoration engineering quality inspection center of the provincial quality inspection institute with Mr. Lin's questions. He told that the quality of tempered glass products is mixed because they are still in their infancy. Director Nie reminded that when purchasing tempered glass products, you should not blindly believe in the thickness, but carefully check whether the purchased glass products have bubbles, and you can go to the official website to check whether the tempered glass has passed the national certification

according to Mr. Lin, he bought a well-known brand tempered glass bathroom in Jiangxi building materials market last April. "At that time, the shopping guide told me that tempered glass was fired at a high temperature of more than 1000 degrees, which was stronger than stainless steel." Mr. Lin said that he was moved to buy the bathroom at that time because he saw that the whole bathroom made of tempered glass was beautiful, coupled with the safety assurance of the shopping guide. Unexpectedly, in October last year, there was a crack in the place where the handle was installed on the bathroom door, and the crack continued to grow as time went on. On October 15, the bathroom door cracked and fell down by taking root in the system of automobile OEMs and parts factories, leaving the bathroom full of glass fragments. Although the dealer later came to replace a new bathroom door, Mr. Lin was still afraid that the glass would suddenly burst again

at the same time, the consumer Mr. Liu also reported to this newspaper that the toughened glass coffee table he bought suddenly burst. "Toughened glass is the original piece of glass in 7. The requirements of the sample in the sample box are very strict. It is heated to 700 ℃ in the tempering furnace and then cooled evenly and rapidly. This production process makes the toughened glass have 3 to 5 times higher bending and impact strength than ordinary flat glass. Generally speaking, the toughened glass produced by glass manufacturers with national certification will rarely burst. But at present, there are some ordinary glass on the market After thickening, it pretends to be tempered glass, so it is easier to burst. " According to director Nie of the interior decoration engineering quality inspection center of the provincial quality inspection institute, which is responsible for the inspection of tempered glass products, one way to distinguish between tempered glass and ordinary glass is to see the shape of the broken glass. Ordinary glass with sharp edges and corners and broken into large sections, and tempered glass into small particles

"when purchasing tempered glass products, many consumers think that the thicker the glass, the better the quality and the less likely it is to break. In fact, this is a consumption misunderstanding, and consumers should pay more attention to checking whether there are bubbles in the glass." When talking about how to choose qualified tempered glass products, director Nie reminded consumers not to blindly pursue the thickness of glass, but to check whether there are bubbles in the glass. If there are obvious bubbles, such tempered glass will crack or even break with the expansion and contraction of heat. In addition, director Nie reminded that generally speaking, the quality of tempered glass certified by the state can be guaranteed. As long as you know the exact name of the tempered glass manufacturer or manufacturer, you can check whether the product has passed the certification from the official website of China National Certification and Accreditation Administration (WW · introduction to the recycling process and current situation of carbon fiber composites
