Have you ever encountered that you have spent several thousand yuan on the car film, but the windshield blisters, poor sun protection, no heat insulation, pungent smell in the car, etc., then you may have stuck a substandard solar film.
On the occasion of the 3.15 Consumer Rights Day, Shanyou Dishan Co., Ltd., as the setter of the national standard and industry standard for window films, will use simple methods to identify solar films with you to remove the false and keep the truth.
Look at appearance
First of all, high-quality solar film generally uses optical grade polyester film as the substrate, and is processed by precision coating. It should have uniform color, clear perspective, and no bubbles, impurities, scratches, etc. This is an effect that cannot be achieved by using inferior substrates and machines with poor performance. We call it "look at appearance".
Second test intensity
Secondly, the explosion-proof performance of the membrane mainly depends on its mechanical properties. When purchasing, consumers can cut the film to the width of a thumb, peel off the release layer and pull it with bare hands. The one that does not break easily is a high-quality film. We call it "intensity of inspection".
Three smells
Thirdly, the odor of the solar film mainly comes from the glue layer. Tear off the release film and smell it. It is a good film if there is no pungent irritating odor. We call it "smelling".
Four questions about parameters
Infrared and ultraviolet blocking is an important characterization of the thermal insulation and protective properties of the film. The high-quality solar film has high infrared and ultraviolet blocking data at the same time under the state of clear perspective. By asking and comparing the infrared and ultraviolet blocking data of the film, you can have a basic understanding of the performance of the film. So when choosing a film, don't ignore the "ask parameters" at the end.
Of course, these are just simple and basic methods to identify the pros and cons of solar films. For accurate identification, it is much more than that. Some also need to use equipment and facilities. For example, strength and impact resistance tests are the following scenarios:
▲(Unfilmed glass) Tire impact test
▲(Film glass) tire impact test
There are many types of hazardous substances detection as follows:
To confirm the parameters we are asking, we also need a special "solar film tester", or a more accurate "spectrophotometer".
Of course, if you have time and hope to use the solar film in more detail before you dare to use it with confidence, then you can contact the factory, and our professionals are willing to provide you with detailed answers. Because the solar film national standards, industry standards and application technical specifications contain far more rich and complex content than the above.
We are Changzhou Shanyou Dishan Protective Material Manufacturing Company, and a professional solar film manufacturer under China Aerospace. We have been in the solar film industry for 15 years. In addition to producing solar films, we also produce functional films for building glass and safety and explosion protection. , Antibacterial, anti-fog and other protective film products, "aerospace quality, domestic products" will always be our goal as a Chinese brand enterprise of solar film. With us, you can spend with confidence.
Integrity 3.15, Yamayu will act with you!
