[China Glass Network] With the continuous development and improvement of the construction industry, the glass insulation film accompanying it is constantly improving itself, making it more adaptable to the pace of the construction industry, while the glass insulation film is also brought to the construction industry. With a greater advantage, people are increasingly convinced of the wide application of glass insulation film. So how does the glass insulation film make people believe in it more and more?
In fact, the rise of glass insulation film in China is not very long, but in fact, the application of glass insulation film in the international are not between the day and night, as early as the last century, glass insulation film has been in the United States and other European countries. It has been widely used, but the glass insulation film is not used in the construction industry but in the aerospace industry. However, with the improvement of people's living standards and the importance of energy, there is protection for their own safety. The application of glass insulation film has gradually involved in the construction industry. By the beginning of this century, glass insulation film has spread to China and began to be widely used. But many people still don't understand the functions and benefits of this emerging product, let alone distinguish the quality of the film.
The glass film is a high-tech product with extremely complicated production process, and its data detection needs to be completed by using a special inspection mechanism using advanced equipment. However, there are many kinds of glass films on the market, and the quality is uneven. How can the ordinary consumers quickly and easily identify the pros and cons of the glass film and the true and false? The following methods are recommended:
1. Seeing - Observing the clarity of the clear glass film is an important indicator to ensure the field of view. Regardless of the color of the film, please pay attention to whether the outer contour of the object is clear through the film glass. The inferior film may have a misty feeling or even cause the outer contour of the object to be deformed. The high quality film is very high in color and clarity. There will be no foggy phenomenon with unclear vision;
2. Nasal smell - tearing off the lining smelling inferior glass heat-insulating film usually uses pressure-sensitive adhesive, the glue is not stable enough, the quality is not good, contains a lot of benzaldehyde molecules, will volatilize under sunlight, and produce odor, and The special insulation film is almost tasteless;
3. Hand touch - high-quality glass insulation film feels thick and smooth, low-quality glass insulation film is very soft and thin, lacks sufficient toughness, and easy to wrinkle;
4. Seeing - the high-quality glass heat-insulating film has high definition, and the high-quality film pigment is evenly blended in the film. It is durable and not easy to change color. It will not be discolored by the scraper during the sticking process. The color of the inferior film is in the bonding adhesive, the inner liner of the film is torn off, and then the nail is scraped off, and the color is dropped;
5. Rubbing with chemical reagents such as alcohol, gasoline, asphalt cleaner, etc. Because the inferior glass heat-insulating film is only dyed by the glue layer, or only the glue layer is coated with UV-blocking agent, so remove the protective layer of the film and wipe the glue layer, ie Visible fading, or using the instrument test, you can find that the UV is greatly reduced;
6. Anti-scratch high-quality film surface has a layer of anti-scratch layer, which can protect the film surface from being scratched under normal use; if there is no anti-scratch layer protection, the film will be scraped off by the tool. Scratches reduce the clarity of the film and can also seriously affect the life of the film. You can use your nails to scrape back and forth on the glass film (non-lining). If you can easily scratch the scratches, it must not be a good quality glass film;
7. The warranty period of the building glass film is 10 years or more. The shelf life of the auto glass film is 8 years or lifetime. It will vary according to the specific product, but the difference should not be too large;
8. Technical parameters The parameters of general glass insulation film include light transmittance, UV blocking rate, infrared blocking rate, total solar blocking rate, tensile strength, peeling coefficient, shading coefficient, internal/external reflectance, and explosion-proof coefficient. , the age of use, etc., according to these parameters to determine the thermal insulation effect of the glass insulation film, explosion-proof safety effects and prices, etc.;
9. Whether the outer packaging and materials of the products sold have the detailed product model, address, telephone number, website address and barcode of the original manufacturer. In addition, if you are using the original uniform publicity logo, authorized dealers can use all the original publicity logos, otherwise they will be held liable for infringement; it depends on whether there is a valid authorized distribution certificate.
Of course, the above methods select the appropriate method according to the specific situation. Under normal circumstances, some professional parameters or the like need to be solved by professionals, so it is good for the consumer's interests and personal safety suggestions. Go to a franchise store and try not to go to a small integrated store or wholesale office. Because sometimes people will be shoddy, professional brands or big brand franchise stores are determined by national inspections and brands. It is necessary to guarantee the quality and accept the inspection by the state and relevant departments, so consumers should make careful decisions. To ensure a healthy life.
