When customers buy the solar film, it is difficult for the naked eye to see the difference in performance. However, the LS180 solar film transmission meter can quickly and easily detect and compare the infrared, ultraviolet and visible light transmittance properties of the solar film.
The main function of the solar film is insulation. For the purpose of insulation, first let’s learn some knowledge of solar spectrum. In the solar spectrum, the infrared region accounts for 53% of the total solar energy, the visible region accounts for 43%, and the ultraviolet region accounts for 4%. The infrared zone is the main source of heat in the sun. Therefore, the main reason for solar film insulation is to remove infrared rays.
In the current Chinese market, there are many types of membranes, and the quality is also uneven. For ordinary customers, it is difficult to distinguish the quality of film quality by the naked eye. Moreover, for different models of the brand film, ordinary customers can only choose macro parameters such as color, but it is difficult to distinguish the difference in performance.
The LS180 solar film transmission meter is a meter that can quickly and easily detect and compare the infrared, ultraviolet and visible light transmittance properties of the solar film. Linshang Technology- a professional manufacturer in China. In the brand solar film flagship store, LS180 solar film transmission meter will also be provided for customer to experience and compare.|
Some high-quality solar films are designed to ensure high visible light transmittance and high infrared rejection rate, but due to technical and cost-effective reasons. It is still impossible to achieve idealized visible light full penetration and infrared full barrier.
In the technical parameters of high-quality film, the UV rejection rate is generally not less than 98%, or can be up to 99%, and the inferior film is lower than this index. Generally, the solar film with high light transmittance and high heat insulation rate requires to have high resistance to infrared rays to achieve heat insulation. And at the same time, the visible light is highly transparent to ensure that the driving sight is not blocked by the solar film. The following are the points to judge the performance of the solar film:
1, high UV rejection rate, the higher the better.|
2, high infrared rejection rate, the higher the better.
3. Low visible light rejection rate.
Sun film brand merchants generally mark these three parameters in the manual. The quality of the solar film can be reflected through these three parameters. Testing with the LS180 solar film transmission meter is the best way to avoid business scams.
