For laymen, it is easier to identify single fireproof glass, and it is really difficult to identify composite fireproof glass!! Now let's talk about the fake category of composite fireproof glass! In previous articles of others, it can be seen that many articles mentioned the types of fake composite fireproof glass:

1、 Pretend to be true

Some unscrupulous manufacturers simply do not have the factory guarantee ability to monitor the composite fire-proof glass products or do not have the production capacity, so they try their best to buy several pieces of cesium potassium composite fire-proof glass from other families as samples and send them to the fire-proof building materials quality inspection center for type inspection, defraud the inspection report and obtain the market access qualification. In fact, in the actual production, the raw materials, processes, equipment and testing methods reduce the standard requirements or even completely do not meet the requirements, steal work and materials, pretend to be genuine, and then wantonly sell their own fake and shoddy products.

2、 Falsification with certificate

Although some composite fireproof glass manufacturers have certain production capacity and also hold 2 or 3 inspection certificates, they generalize and falsely claim that all their composite fireproof glass products of all specifications are qualified, so as to grandly promote a large number of their various fake and shoddy products in the market, which is a common "certificate fraud". In fact, an inspection report only proves that one type inspection of composite fireproof glass with one thickness and one specification is qualified, which can not replace all specifications of composite fireproof glass products, and "is only responsible for the incoming samples". This method of counterfeiting is more obscure and deceives some users who do not understand standards and norms.

3、 Infringement and counterfeiting

Some illegal manufacturers of composite fireproof glass infringe on others' technical patents or exclusive rights to registered trademarks, fake others' trademark names, packaging, decoration, forge or falsely use certification marks, forge origin and issue false advertisements, and mix the market.

4、 Film counterfeiting

The ways of counterfeiting composite fireproof glass emerge one after another, and another trick is film counterfeiting. Some unscrupulous manufacturers in society ignore the objective fact that the manufacturing process of single-chip composite fireproof glass is complex and the raw materials are expensive. They blindly cut corners on work and materials and pursue interests. They even paste a layer of organic film on ordinary glass, falsely claiming that it is single-chip composite fireproof glass and defrauding the inspection report. In fact, they bought cesium potassium composite fire-proof glass products from other families, pasted their own thin organic glue, sent them for testing and defrauded them of certificates.
