[China Glass Network] In recent years, there have been five-star hotels in China that have imported insulation film for glass windows to save energy and reduce energy consumption. However, in actual use, most of them reflect that the heat insulation effect is not obvious, and the air conditioning energy is basically not reduced. Consumption, therefore, there is doubt about the energy-saving effect of the thermal insulation film, they do not know the reason, why is the imported thermal insulation film stuck on the car, and it has no effect on the glass of the hotel?
I want to understand this reason must start from the owner's architectural form. First of all, because the five-star hotel is well funded, it will not use the low-end dye film, it will use imported insulation film, and the imported insulation film is magnetically controlled. The production process of magnetron sputtering is a reflective heat-insulating film, which is applied to a PET substrate by sputtering a metal such as nickel or silver, and these metal layers selectively emit sunlight. The infrared rays in the reflections go back.
The visible light transmittance of the magnetron film should be improved, and its resistance to infrared heat is gradually weakened. For example, there is a high-end magnetic control film, which has a light transmission of 60%, and about 40% of infrared heat cannot be blocked.
The five-star hotel glass is mainly made of LOW-E insulating glass. The LOW-E insulating glass itself is energy-saving glass. It is formed by vacuum magnetron sputtering, plating several layers of low-radiation materials and other metal compound films. The layer has the characteristics of high visible light transmission and high reflection to the far-infrared rays. Its heat-insulating principle and blocking band are the same as the magnetic control film, so that even the magnetic control film is attached to the LOW-E glass, and the heat insulation effect is applied. Not obvious, because the joint part of the two has overlapped, and there is no superposition effect.
For example, there are two gaps in the dam, only one is blocked, even if we block one of the gaps and then the other, the other is not blocked, and the water flows. Sticking the magnetron film on the LOW-E glass is like blocking it again in the same gap, and the other gap is still flowing, meaning little.
The blocking band of the same material is basically the same, and the blocking band of the different materials is different, and it can be complementary on the barrier. Therefore, in order to improve the energy-saving efficiency of LOW-E glass, it is only by selecting products with different materials to block the "other gap", in order to improve the energy-saving efficiency of LOW-E glass.
ENP Han film can selectively penetrate visible light due to its nano-characteristics, blocking 97% of infrared thermal energy, which can make up for the insulation defects of LOW-E glass and improve energy-saving efficiency.
At present, ENP Han membrane can not only meet the glass energy-saving requirements of star-rated hotels, but also has the service life of more than 15 years. It does not affect the lighting in the hotel, nor does it interfere with wireless signals such as blocking mobile phones. Good companion.
