Thermal insulation principle:

The energy of the sun is transmitted to the earth in the form of electromagnetic waves in the form of radiation. The solar energy entering the earth’s surface includes ultraviolet light, visible light (wavelength range: 380-780 nm) and near-infrared region (wavelength range: 780-2500 nm). nm). Ultraviolet light can be divided into near ultraviolet light (UVA, wavelength range 315-380nm), mid-ultraviolet light (UVB, wavelength range 280-315 nm) and far ultraviolet light (UVC, wavelength range from 100-380nm). 280 nm). Near ultraviolet rays (UVA) can penetrate clouds and glass into indoors and cars, and can penetrate into the dermis layer of the skin, causing sunburn and sunburn. It is also a major factor in skin aging and wrinkles. Mid-ultraviolet (UVB) rays are absorbed by stratospheric ozone, causing sunburn and skin redness, swelling, heat and pain, and are the most carcinogenic. Far ultraviolet light (UVC), although its short wavelength and high energy is more dangerous, it can be absorbed and blocked by the ozone layer, so it will not reach the earth’s surface and will not harm human skin. That is to say, the insulation paper’s blocking of sunlight will mainly target the sunlight energy that contacts human skin through the glass. According to the definition in the American Society for Testing and Materials (ASTM), energy in the solar wavelength range of 300-2500 nm will be discussed by the glass and thermal insulation paper industry. Its energy ratio is ultraviolet (300-380 nm) accounting for 3%, visible light (380-780 nm) accounting for 44% and near-infrared (780-2500 nm) accounting for 53%.

When radiated energy hits an object, its energy will be transferred in three ways: penetration (T), reflection (R), and absorption (A). The heat energy absorbed by the object will be re-radiated as far-infrared energy according to its characteristics, and the ability to re-radiate is usually called emissivity (Emissivity). Therefore, the heat-blocking ability of thermal insulation paper comes from reducing the entry and re-radiation of light and heat energy (including ultraviolet, visible light and near-infrared rays), which is generally called the Total Solar Energy Rejection (TSER). For example, under different visible light transmittance conditions, different technologies can be used to achieve the same total thermal insulation rate.

Generally, thermal insulation paper reflects and absorbs solar heat energy to achieve thermal insulation effect.

Reflective solar thermal energy type: Most are made of metal, such as silver, titanium, iron, aluminum, etc. Reflect energy directly out of the room. Although reflection can greatly block solar heat energy, it also causes indoor reflection.

Solar thermal type: Most of them absorb heat energy in dark colors and store it on thermal insulation paper and glass. There are many colors to choose from, but the heat absorption effect will decay over time, so its heat insulation effect is poor.

Most thermal insulation papers can block UV rays and can effectively reduce the fading and cracking of indoor furniture caused by ultraviolet rays.

“GAMA Nano Ceramic Insulation Paper” has the advantages of solar energy and reflective solar energy. The main structure is ceramic nanocomponents. Using nanotechnology, the coating is ground to 5 to 50 nanometers. We know that when the object is as thin as one It will transmit light to a certain extent. It is by taking advantage of this characteristic that visible light waves can be penetrated, but ultraviolet and infrared light waves cannot be penetrated, resulting in anti-infrared materials. Originally, these materials were first used in military weapons such as the United States’ stealth weapons. The surface of the fighter jet’s body uses this high technology to make “insulation paper” to reduce the penetration of ultraviolet and infrared rays and increase visible light.

Points to consider when choosing thermal insulation paper:

Heat insulation

As the name suggests, energy-saving thermal insulation paper has the main function of blocking heat sources. Pasting thermal insulation paper on the glass of your car can effectively isolate the thermal radiation of solar energy. Generally speaking, the total thermal insulation rate of automobile insulation paper is 40% to 60%, which can meet the insulation needs of ordinary car owners. More than 60% can be considered a high standard, because the total thermal insulation rate of 40% to 60% is Thermal paper can be used with air conditioners to prevent the cold air in the car from flowing out, accelerate the cooling effect in a short time, save energy and reduce fuel consumption.

UV protection

Ultraviolet rays are the killer of skin aging and cancer. It also affects car interiors. Therefore, in order to reduce the damage of ultraviolet rays, in addition to general daily sun protection measures, it is also a good way to use heat-insulating paper for your car. Currently, generally commercially available thermal insulation papers can achieve a UV protection rate of 98~99%, which can easily protect human skin and prevent aging and cracking of car interiors.

Glare isolation

Drivers should have experienced eye discomfort caused by glare from the sun or the lights of oncoming cars while driving, especially when facing the setting sun at dusk, or at night when the headlights of cars coming from behind are illuminated through the rearview mirror. Dazzling glare makes it impossible for drivers to accurately grasp the conditions of oncoming vehicles from behind, which often greatly affects driving safety while driving. Choosing car insulation paper can effectively block glare, allow car owners to effectively control the condition of the car, and increase driving safety.

Protect privacy

Most car owners (especially women and car owners who pay special attention to privacy) do not want their every move in the car to be clearly seen by people outside the car, so they often choose car partitions with darker colors. It is hoped that the hot paper can prevent peeping and increase the privacy effect by reducing the outside-in perspective through high external reflection, and avoid coveting or malicious damage by criminals due to people or property in the car. Whether car insulation paper can provide good privacy has become an important consideration for car owners when choosing stickers. However, drivers are reminded that they should also pay attention to the clarity of vision from the inside to the outside of the insulation paper to avoid affecting driving vision and safety. cause impact.

Safety and explosion-proof

Sudden flying stones while driving, tire skins falling off gravel trucks on the road, traffic accidents, and even malicious damage by gangsters who covet the property in the car often cause damage to the car, broken glass, scattered glass, and scattered glass in the explosion. Glass is often the first harm to the human body when an accident occurs. The thermal insulation paper with explosion-proof function can reduce the degree of harm to the human body caused by accidentally broken glass flying, and even deter criminals from being able to completely break the glass and obtain property at the first time of committing the crime, thus achieving the effect of deterring crime. The quality of the explosion-proof function depends not only on the quality of the base material of the thermal insulation paper itself, but also on the quality of the thermal insulation paper itself, which allows the thermal insulation paper to completely adhere to the glass. When impacted by external forces, the glass can still adhere to the thermal insulation paper without Broken glass will fly and injure people.

Reduce energy consumption

Many drivers often have the habit of turning on the air conditioner as soon as they get into the car, because the hot weather or stuffy cabin often makes people sweat profusely or even make them dizzy. However, using air conditioners can easily lead to high fuel consumption and increase the burden on the car. If you can put thermal insulation paper on your car to block the heat source of sunlight, the effect of the cooling room will no longer be compromised and fuel consumption will be reduced.
