First, the contrast light wattage is not the same Second, the double film is attached, the test film and the film are inconsistent. 4. The fake on the glass and other means to deceive the consumer to consume, so that the consumers who do not know the truth have a big deal. I thought it was cheaper! Especially the ordinary consumers who don't understand optics, building glass film expertise, are very vulnerable to being deceived. Therefore, before purchasing the architectural glass film, the operator must be required to provide the relevant test documents of the test data of the film and the actual test results on the spot. Especially for any film store that exaggerates the data, it should be more vigilant to prevent being deceived.

Third, whether the data published by the merchants is true and reliable, such as: whether there is any forensic report, there are authoritative organizations such as Window Sunlight Group in the world, and the official department of the Ministry of Public Security and other domestic departments for identification; there are no internationally accepted standards for testing instruments, whether the data is true or not. speak. Some brands are arbitrarily exaggerating the performance of the customer's unconditional test data (some irresponsible data can not be achieved theoretically), making the building glass film market difficult to distinguish, low-priced products popular.
