However, due to the characteristics of light transmission, fire prevention (smoke prevention, fire prevention and heat radiation prevention), sound insulation and impact resistance, ordinary people can judge whether it is fire-proof glass or ordinary glass according to these characteristics. Fireproof glass is generally used for fireproof doors and windows and fireproof partitions.

Identification method of true and false fire-proof glass
1, false is true.
Some unscrupulous manufacturers simply don't have the factory support ability or production capacity to monitor fire-proof glass products, so they try their best to buy several pieces of cesium-potassium fire-proof glass from other companies as samples and send them to the fire-proof building materials quality inspection center for type inspection, thus defrauding the inspection report and obtaining market access qualification.
In fact, in actual production, raw materials, processes, equipment, testing methods, etc. They are all reducing or even completely inconsistent, cutting corners, confusing the fake with the real, and then selling fake and inferior products.
2. Authentication fraud
Although some fire-proof glass manufacturers have a certain production capacity and hold two or three inspection certificates, they are partial and lie that all the fire-proof glass products of all specifications are qualified, so as to promote a large number of other fake and shoddy products in the market, which is a common "certification fraud".
In fact, an inspection report only proves that a kind of fireproof glass with one thickness and one specification is qualified in a type inspection, and it cannot replace all specifications of fireproof glass products, and it is "only responsible for incoming samples". This kind of fraud is obscure and deceives some users who don't understand standards and norms.
3. Tort and fraud
Some manufacturers who illegally produce fire-proof glass infringe on others' exclusive right to use technology patents or registered trademarks, counterfeit others' trademark names, packaging and decoration, forge or fraudulently use certification marks, forge places of origin, publish false advertisements and other unfair competition behaviors, thus confusing the market.
4. Movie fraud
There are many ways to fake fire-proof glass, and another trick is to fake the film. Some unscrupulous manufacturers in society ignore the objective fact that the manufacturing process of single piece of fireproof glass is complicated and the raw materials are expensive, blindly cut corners and pursue benefits, and even put an organic film on ordinary glass and lied that it is fireproof glass, thus defrauding the inspection report.
In fact, it is a trick to steal columns, buy other cesium-potassium fire-proof glass products, paste organic thin glue, and send them for testing to defraud certificates. Fire-proof glass is a kind of public safety product, which has been brought into national compulsory management. The product quality of fireproof glass is closely related to economic construction and people's life and property safety.
Once fake and shoddy fire-proof glass is put into use, it will cause long-term harm to social security environment. Therefore, exposing the tricks of counterfeiting fire-proof glass, cracking down on counterfeit illegal manufacturers and rectifying the fire-fighting product market are major events that the whole society should attach importance to.
