Starting from the end of December 2023, based on information reported by the masses, reporters conducted unannounced visits to some markets selling fire-resistant glass in Tianjin and Hebei. After contacting many people in the industry, they learned that the quality of fire-resistant glass produced by individual companies on the market is now If the glass does not meet the standard, ordinary tempered glass may be used with a fireproof label and sold as fireproof glass. These products are of low quality and low price, posing hidden dangers to fire safety.
reporter: "Are there many such light markings?"
Industry insiders: "There are many."
reporter: "There are light markings that are fake fireproof and are also used on fire-resistant windows?"
Industry insiders Source: "On fire-resistant windows."
Industry insiders told reporters that the substandard fire-resistant glass flowing into the market has a price advantage because it does not adopt strict industrial processes. According to the requirements of the national mandatory standard "Code for Fire Protection Design of Buildings", for buildings with a height greater than 54 meters, each household should have one room, and the exterior windows should use fire-resistant windows with a fire resistance integrity of not less than 1 hour. If the fire-resistant glass installed is unqualified, once a fire breaks out in a high-rise building, the fire-resistant windows will not be able to isolate the impact of the flames, which will greatly shorten the escape time of the residents, and the consequences will be disastrous. The country has always focused on quality inspection of fireproof glass. Where is the fake fireproof glass that cannot strictly play a fireproof role produced? Who would make fake products on fireproof glass so illegally?
According to the instructions of insiders, the reporter came to Shunbo Glass Technology Co., Ltd. in Tianjin, which is a company specializing in the production of fire-proof glass. When walking into the company's production site, the reporter saw two production lines for the production of fire-proof glass. Manager Zhang, the person in charge of the company, told reporters that most of the fire-resistant glass currently on the domestic market is cesium-potassium fire-resistant glass. The so-called cesium-potassium fireproof glass is a product that sprays a layer of cesium-potassium fireproof liquid on ordinary tempered glass and then tempers it.
Manager Zhang of Tianjin Shunbo Glass Technology Co., Ltd.: "It is the kind that is sprayed, in the form of a spray. After spraying, let it sit for two hours and it will react."
Worker of Tianjin Shunbo Glass Technology Co., Ltd.: "Fireproof Use liquid to spray it into a mist, spray one layer, don't let it drip down, it will be mist."
reporters saw on the factory production line that workers held spray cans and simply sprayed on the glass, and the glass was allowed to dry. After drying, the workers began to skillfully mark each piece of glass with a fire protection mark. After further tempering, a piece of so-called cesium-potassium fireproof glass is completed.
However, the reporter saw that another batch of glass that was tempered together with the sample glass was also marked with a fireproof mark on the production line. However, during the entire production process, the reporter did not see the process of spraying fireproof liquid on these glasses and drying them.
Reporter: "Has this fireproof glass been sprayed with liquid?"
Tianjin Shunbo Glass Technology Co., Ltd. worker: "I don't know whether it is sprayed or not."
Reporter: "Is there some that is not sprayed?"
Tianjin Shunbo Worker of Glass Technology Co., Ltd.: "If people want to fake fire protection, just put a mark on it."
Reporter: "Just mark it, right?"
Worker of Tianjin Shunbo Glass Technology Co., Ltd.: "It depends on the customer's requirements. ."
After repeated questioning by reporters, the workers finally told reporters that these fire-proof glass are actually ordinary tempered glass without any fire-proof treatment. At the production site, the reporter also saw that the processing work order clearly stated, "Fire-proof label. ” words. During the investigation,
reporters found that it seems to be an open secret in the industry to produce and sell fake fire-resistant glass with only fire-resistant labels. Not only Tianjin, but also a fireproof glass manufacturer somewhere in Hebei is also engaging in the same fraud.
Reporter: "Is there fireproof glass?"
Worker at the bright hollow tempering factory: "There is no fireproof glass."
reporter: " Is the fire prevention directly marked? "
Shining Hollow Tempering Factory Worker: " The glass is the same, and the label is fireproof. We will give you whatever label you want. "
Staff member of Xianghe Yongbin Glass Factory: "Ordinary tempered glass sells for 50 yuan per square meter, so we will give it a price of 50 yuan per square meter and put a fire protection label on it. "
Shuangfu Aluminum Plastic Doors and Windows Co., Ltd. Manager Zhao: "To put it bluntly, it is fake. Just apply the fire protection label. Many companies do this. "
Manager Zhao of Shuangfu Aluminum-Plastic Doors and Windows Co., Ltd. told reporters that their company can also make cesium-potassium fire-resistant glass, which is more expensive than tempered glass that only has a fire-resistant label.
Manager Zhao of Shuangfu Aluminum-Plastic Doors and Windows Co., Ltd.: "The price of the marked only ones is the price of normal white glass. White glass sells for 45 yuan per square meter, and fireproof glass is generally 80 yuan per square meter. "
Manager Zhao said that they can also provide corresponding qualified inspection reports for customers who purchase cesium-potassium fire-resistant glass.
Manager Zhao of Shuangfu Aluminum Plastic Doors and Windows Co., Ltd.: "My inspection report is fire-resistant for one and a half hours, but the actual glass It can only achieve fire resistance for half an hour. "
Sure enough, the reporter saw in the fire resistance performance column of the inspection report provided by Manager Zhao that the fire resistance integrity was greater than or equal to 1.5 hours. Manager Zhao remained silent on how the company obtained the qualified inspection report, but industry insiders revealed that because the product is an enterprise Go to the management department to submit it for inspection yourself, so the company will prepare expensive qualified fire-resistant glass, pretend to be its own product to submit for inspection, defraud the qualified inspection report, and then openly sell the fake and shoddy products.
But even with a product certificate, counterfeiting In order to ensure the success of counterfeit goods sales, companies are also very well prepared for some details. At some construction sites where buildings are installed, building supervisors generally conduct on-site inspections of glass products. For this reason, some fireproof glass production and sales companies told reporters , when encountering this situation, they will specially equip the construction party with several pieces of qualified high borosilicate fire-proof glass to cope with on-site random inspections.
Salesperson at Ruidafeng Glass Distribution Office: "If you want to do random inspections, it is recommended that we We make samples specifically for you, specifically for testing. "
reporter: " When the time comes, we will be responsible for random inspections. It is up to you to provide several qualified products to the order. "
Manager Xie of Tianjin Baojian Energy Saving Glass Co., Ltd.: " Yes. Reporter
: Does use high borosilicate? "
Manager Xie of Tianjin Baojian Energy Saving Glass Co., Ltd.: "If you want nothing wrong, just use high borosilicate. I am very familiar with high borosilicate. "
Just like this, the state compulsorily requires the installation of fire-resistant glass. The quality inspection management department has fire-proof glass in the testing process from production to application site. Under the deceptive operation of some illegal enterprises, from production and processing to false inspection to obtain product inspection reports, Then to respond to on-site random inspections by changing the situation, fake and shoddy products have entered the consumer market.
reporter: "They are all residential buildings, right?" "
Manager Li of Longdun Glass Co., Ltd.: " is all residential. "
reporter: " I'm talking about fire-resistant glass. "
Manager Li of Longdun Glass Co., Ltd.: " is fire-resistant glass. "
reporter: " Did you use cesium potassium or something else? "
Manager Li of Longdun Glass Co., Ltd.: " Cesium Potassium. "
What is the difference in fireproof performance between fake and shoddy fireproof glass and real fireproof glass? Before the party, the 3.15 investigative reporter brought fireproof glass that met the national standard and fireproof glass samples obtained from many counterfeit companies. We arrived at the National Fire Protection Inspection Center. The staff first tested the fire-resistant glass that complied with the national standard. After burning it for 65 minutes, the fire-resistant glass did not show any melting, cracking or deformation. After that, the staff tested the fire-resistant glass samples obtained by the reporter. Testing, the results are surprising.
