Distinguishing method of true and false fireproof glass

I. fake as true

Some unscrupulous manufacturers do not have the factory guarantee ability to monitor fire-proof glass products or do not have the production capacity, so they try to buy several pieces of cesium potassium fire-proof glass from other families as samples and send them to the quality inspection center of fire-proof building materials for type inspection. They cheat the inspection statement and obtain the qualification of market access. In fact, in practical production, the materials, processes, equipment and testing methods reduce the specification requirements and even do not meet the requirements, cut corners on work and materials, pass the fake as the real, and then sell their own fake and shoddy products on a large scale.

II. Counterfeiting with certificate

Although some fire-proof glass manufacturers have production capacity and also hold 2 or 3 inspection certificates, they make a partial generalization and falsely report that all their standardized fire-proof glass products are qualified, so as to grandly promote various other fake and shoddy products in shopping malls & quot; Fraud with certificate & quot;. In fact, an inspection statement only proves that one type inspection of fire-proof glass with one thickness and one specification is qualified, which can not replace the standard fire-proof glass products, and & quot; Only for incoming samples & quot;. This method of counterfeiting is relatively obscure and deceives some users who do not understand and standardize.

III. infringement and counterfeiting

Some illegal manufacturers of fireproof glass infringe on other people's technical patents or registered trademark rights, fake other people's trademark titles, packaging, decoration, fake or falsely use certification marks, fake origin and issue false advertisements, and mix up shopping malls. For example, single piece cesium potassium fireproof glass is a patented product of Guangdong Jingang Glass Technology Co., Ltd., which is listed as a national key torch plan project, a national key new product and a promotion project of scientific and technological achievements of the Ministry of construction in 2002, but some manufacturers pretend to be & quot; Single piece cesium potassium fireproof glass & quot; Our product name is sold in shopping malls.

IV. film counterfeiting

Methods of fake fireproof glass emerge one after another, and another trick is film fraud. Some unscrupulous manufacturers in society, regardless of the objective fact that the manufacturing process of single piece fire-proof glass is complex and the raw materials are valuable, blindly cut corners on work and materials and pursue interests. They even put a layer of organic film on the general glass and lied that it is fire-proof glass, which deceived them into checking the statement. In fact, they bought cesium potassium fire-proof glass products from other families, pasted their own thin organic glue, sent them for testing, and cheated them of certificates.

Fireproof glass is a public product that is classified into national compulsory treatment. The product quality of fireproof glass is closely related to economic construction and people's life and property. Once the fake and shoddy fireproof glass is put into use, it will damage the social environment for a long time. Therefore, it is a major event that the whole society should pay attention to exposing the tricks of fire-proof glass counterfeiting, cracking down on illegal manufacturers and sorting out fire-fighting product shopping malls.
