Must-read: mainstream explosion-proof membrane of the evaluation report - explosion-proof membrane - the automotive supplies industry
Explosion-proof membrane Test used a number of new methods Photocatalyst The test is also in operation. We are also exploring a new way of expression, make the industry more closely with your distance.
Test shows The main test Explosion-proof membrane Visible light perspective rate and the actual heat capacity of explosion-proof membrane.
Addition Farate product is provided by stores, "explosion-proof film quality detector" test products, visible and infrared penetration rate perspective, the other are used canopy transmittance precision instrument TM2000, tested on visible light perspective rate . The explosion-proof membrane of the actual heat capacity as a comprehensive performance, there is no simple direct measurement instrument, we used an indirect measurement method.
Proof membrane in the actual measurement of heat capacity, we use a special device, the device from the light source, frame, two precision Electronic Thermometer form. Light source installed in the middle bracket, bracket is divided into between the same two tests. The two precision electronic thermometers were installed between the test center. Test, explosion-proof membrane covering the measured test room in one of the top, measuring both sides of the initial temperature. Cooling measures need to be taken before testing to allow both sides of the initial temperature of not more than 1 degree Celsius, in order to reduce test error. We turn on the light exposure 3 minutes, then twice the temperature measurement, temperature deviation, the more both sides. Value larger the explosion-proof membrane under test the better performance of the real heat!
Be explained that, due to visible light accounts for about 44% of the total energy, therefore, more explosion-proof membrane insulation performance must take into account the perspective of rate of visible light explosion-proof membrane. The same rate in the visible perspective where only directly comparable.
Scorching summer, in order to deal with the strong sun, the majority of owners would buy a new car to the car after the paste Car explosion Membrane.
To Auto Explosion-proof film paste, is easiest to solve the problem car sun most direct way, it can effectively block solar heat, thus reduce the cooling load, improving fuel efficiency, ease the engine load, prevent fading of aging goods vehicle to protect owners skin from harmful UV rays. Car explosion-proof membrane
as a huge market has developed, so businesses have to enter the market in order to share the profits. Currently, many brands on the market explosion-proof membrane, the price is also very different. But the real strength of explosion-proof membrane manufacturers to produce quality not many, a considerable part of the anti-film products for the OEM OEM products, and some low-cost products is no guarantee of quality. Paste these substandard products, and can not play its due role, and may even damage the car glass.
Situation facing the consumer market explosion-proof membrane, recently New Express Automotive Test Center explosion on the market mainstream films were evaluated brand, brands, including 3M, Le Pen, northern lights, Farate and FSK, unfortunately there is no Johnson & Johnson and prestige of the solid for evaluation.
3000 yuan Farate Champion K-375 (for the front windshield) Market Reference Price: 3500 yuan / ordinary cars Test equipment: Farate store's "explosion-proof film quality detector" Test results: visible Perspective rate: 74 percent infrared transmittance: 14% Summary: Farate Champion K-375 explosion-proof membrane of the visible light perspective rate of the front windshield glass, safety requirements, the infrared transmittance levels are relatively low, has good insulation.
Farate champion TK-9096 (for side windows and rear windscreen) Market Reference Price: 4000 yuan / ordinary cars Test equipment: Farate store's "explosion-proof film quality testing instrument" Test results: visible Perspective rate: 19% infrared transmittance: 10% Summary: Farate champion TK-9096 explosion-proof membrane of the visible light perspective rate is very low, stick side windows shall be retained side Rearview mirror Area is not posted, as observed when driving at night affect the external environment. The infrared transmittance is also a lower level, there is good insulation.
2000 yuan Le Pen Blue Diamond BDL506 (for side windows and rear windscreen) Market Reference Price: 2200 yuan / ordinary cars Test equipment: TM2000 Precision Instrument + special thermal transmittance test equipment Test results: Visible perspective: 40% no coatings: the initial temperature of 30.1 degrees Celsius, 3 minutes after the temperature of 38.5 degrees Celsius
When a film: the initial temperature of 29.4 degrees Celsius, 3 minutes after the temperature of 36.5 degrees Celsius
relative temperature difference: -1.3 ° C Summary: Le Pen Blue Diamond BDL506 explosion-proof membrane of visible light perspective rate of side windows and rear windshield of vehicles to meet safety requirements. However, the relative temperature difference of -1.3 degrees Celsius.
3M infinite beauty (for all vehicles) market reference price: 2,800 yuan (front windshield) / ordinary cars Test equipment: TM2000 Precision Instrument + special thermal transmittance test equipment Test results: visible Perspective rate: 80% no coatings: the initial temperature of 29.5 degrees Celsius, 3 minutes after the temperature of 38.7 degrees Celsius
When a film: the initial temperature of 29.0 degrees Celsius, 3 minutes after the temperature of 34.0 degrees Celsius
the relative temperature difference: -4.2 ° C Summary: 3M explosion-proof membrane infinite landscape perspective the high rate of visible light, the relative temperature difference of -4.2 degrees Celsius, a very good insulation, good overall performance.
2000 yuan Farate armored Veyron S44 (for the front windshield) Market Reference Price: Armored Veyron Series (all cars) 1500 Yuan / ordinary cars Test equipment: Farate store's "explosion-proof film quality detector" Test Results: Perspective visible rate: 61% infrared transmittance: 44% Summary: Farate S44 explosion-proof membrane Veyron armored perspective was slightly lower than the visible front window of the security requirements, the infrared transmittance at a relatively normal level, insulation ordinary.
Farate armored Veyron C71 (for side windows and rear windscreen) Market Reference Price: Armored Veyron Series (all cars) 1500 Yuan / ordinary cars Test equipment: Farate store's "explosion-proof film quality detector" Test results: visible Perspective rate: 27%
infrared transmittance: 11%
