Principle: the heat insulation autochemistry vacuum spray plating or magnetron sputtering will aluminum, gold, copper, silver metal multi-layer to close high heat insulation layer metal film. Metal material in shell layer electronic (electronic) generally is not free nucleus bound Puma Ferrari Shoes White , when light irradiation, make the freedom of the waves of light electric field of electronic absorbs light energy, and produce the same frequency oscillation and light, the oscillation and release it with the same frequencies of light, the light is called light reflection. The higher the coefficient of conductive metal Puma Running Shoes Sale , the shallow penetration depth, the higher the reflectivity. These metal layer will be selective sunlight in various of heat energy, including infrared, ultraviolet and visible light to reflect heat, coupled with the color of the membrane of the sun the absorption of heat, then the second to release, with outdoor air flow away part of the heat. Thus effectively have adiabatic effect.

Book of choose and buy: (1) the transparency and definition: this is the car in the film about driving safety is the most important performance. Choose film, the first to consider clarity and transparency, the high quality the clarity of the film can be as high as 90%, and whatever color depth, transparency are very high, won't have the foggy conditions. (2) GeReXing: car paster primary function of heat insulation and, therefore, is to be a good car explosion protection membrane is through the reflection infrared, and to achieve the purpose of reducing the inside temperature. The customer when the choose and buy besides can through standard of insulation rate, and other indicators to understand the stand or fall of explosion protection film outside, still can use intuitive methods to determine whether the film is with a stick, the glass block the sun, use a hand to feel the way its heat insulation effects. (3) : the inferior explosion-proof anti-blast film feels very soft, lack of enough toughness, not resistant to ultraviolet ray, aging sent fragile. But a good explosion protection membrane, one thousand glass breached also stick to broken glass, shiver not splash hurt. (4) the ultraviolet ray separates rate: good membrane this index generally not be less than 98%, high can amount to 99%. High the ultraviolet ray separates rate can effectively prevent the crew by the excess ultraviolet ray, burns skin, still can protect the car stereo the adornment such as the sun is not bad. And inferior film many without this index, or far less than 98% of the standard.
