Teach you to identify strengths and weaknesses membrane

 Teach you to identify the advantages and disadvantages of film
1, definition: no matter the color depth of film, high-quality film should be clearly visible at night than 6m articles, and feeling inferior film Huiyou hazy.
2, handle: with thick smooth film feels genuine sense, and poor film feel thin and crisp, easy to wrinkle.
3, color: high-quality paint film is uniformly dissolved, and in the film, durable and difficult to change, in the paste process The scraper will not scratch coated bleaching. And the color of poor quality film role in the adhesive from the adhesive, the tear film of the liner after the car scratch the nail color for fall, the diaphragm is nails scratched the areas will become transparent, in the film during the film when the scraper scraping, sometimes the color will be off on their own, then this film will change color, fade after one year is more obvious.
4, bubbles: when torn car the plastic membrane lining, and then reunited, the poor quality film will be blistering, high-quality film after the intact complex.
5, insulation: thermal insulation is an important indicator of the glass protection film, and this and feel the naked eye is difficult to identify the. here to tell you a little know-how, through a simple test for comparison: in a tungsten put a close to Che film glass, hand feel a trace of is a high-quality hot film, and immediately feel a hot performance indicates that the insulation problem is poor quality film; if you want to feel the protective film is also heat conductive work, use a small piece of film around the tungsten and the like heat, hot can not touch it indicates poor heat conductivity, the winter do not expect this film to give you energy. and vice versa that can block heat transfer foil, and heat insulation effect.
