Four strokes make false glass film appearance
Popular villas, high-end residences, and automobile users are popular in the glass window film. The glass film has the functions of light transmission, heat insulation, and UV protection. However, if you encounter counterfeit products, you will incur harm. How can I identify fakes? There are four strokes for reference: Check the certificate: There are official test reports. Transparent films generally have to achieve at least 90% transmittance; thermal insulation must block more than 60% of the infrared; UV blocking rate must be 97% -99% to be qualified. Many glass films are often inversely proportional to the heat insulation rate and UV blocking rate, and the high heat insulation rate often means deep color, which in turn greatly reduces the UV blocking rate.
Look at the film: The genuine product is smooth and delicate, and the texture of the hand is very strong when touched. The counterfeit and inferior goods are dull, rough, and unlustrous. It is also important to note that genuine products often do not make so-called anti-counterfeit imprints on the film itself, as this affects the light control of the film.
Testing: Detecting heat insulation is a subject that the human body feels. It feels like it has an effect. You can feel the heat insulation effect of the product simply by using the spotlight.
Physical identification: A CE-Freda Security Film exclusive agent in Greater China, headquartered in Hangzhou, invented a method of identification and applied for a patent. A six-inch photo-size film was cut from the film and attached to a glass frame. The spotlight was irradiated with a spotlight to sense the heat insulation rate. According to the impact resistance set by the warranty book, 0.5 kg of steel ball was used to measure the heat resistance. A free fall hits the suspended frame at a height of 15 meters. If worn, it means that it is a fake or the product is not qualified.
