New technology of Cuiguang thermal insulation paper products!

1. Types of thermal insulation paper development: There are five generations of thermal insulation paper products.

(1) The first generation product is “tea paper” instant glue dyeing film. The disadvantages of this type of film are that it is not insulated, easy to fade, and easy to degumming. Most of them are produced in Southeast Asia.

(2) “Explosion-proof film” is the second generation product after “tea paper”.

This kind of film uses new adhesive and a thicker film layer to improve the explosion-proof effect. It has certain heat insulation and sun protection properties. The heat insulation rate is between 20% and 60%, and the UV light blocking is about 80%. In the past year or two, high-quality thermal insulation and explosion-proof membranes have gradually become the mainstream of the market.

(3) Sunscreen insulation film is a third-generation product.

Also known as thermal insulation paper, space film, etc., the ultraviolet blocking rate can be increased to more than 90%, and the infrared blocking rate can be increased to about 30%-95%. The glue is more viscous, thereby reducing the thickness of the film and increasing the Explosion-proof performance. This type of film is mostly made in the United States, with high light transmittance and clear vision. Metal films are generally reliable in quality for 5 years.

(4) Ceramic insulation film is a fourth-generation product.

Based on the shortcomings of metal films such as interference with radio signals and easy oxidation, we developed nano-honeycomb ceramic technology and used vacuum sputtering technology in the production of ceramic insulation films, creating a unique nano-ceramic insulation paper that solved the problem of metal films. The insurmountable technical problems of the film: no interference with radio signals, especially the short-wave signals of satellites, and never oxidized, because of the extraordinary stability of ceramics, thus ensuring consistent thermal insulation performance and never fading, ceramic thermal insulation paper Using the inherent color of ceramics without adding any dyes, ceramic insulation paper will never fade like dyed metal: Super durable, ceramic insulation paper has a shelf life of more than 5 years: Classic beauty, crystal clear like crystal Transparent beauty, soft color, and the most comfortable visual effect.

(5) Cuiguang nano ceramic insulation film is a fifth-generation product.

The nano patent used in Cui Guang GAMA nano ceramic Cui Guang thermal insulation paper was first used in Japan’s thermal insulation material technology. It can be nanosized up to the negative sixth power of 10. It has the world’s top invention patent for nano ceramic thermal insulation. , using advanced nano-coating technology, ceramic products can be used in aircraft and space stations in outer space, and are widely used in various fields such as automobiles, construction, maritime, clothing, etc. The new generation of Cuiguang E series products can achieve nearly 99% blocking effect in the entire infrared band 780nm ~ 2500nm and ultraviolet 380 ~ 410nm at the same time. It is an industry original and achieves the highest dual-function effect of a single product. Nano ceramics The shelf life of Cuiguang thermal insulation paper can reach 5 to more than 8 years.

2. How to choose high-quality thermal insulation paper:

When driving in summer, sun exposure will not only burn the driver’s skin, but ultraviolet rays may also burn the car interior and age some leather goods. The increase in the internal temperature of the car also increases the frequency of air conditioning and increases fuel consumption. Therefore, it is very necessary to apply thermal insulation paper. However, there are many types of thermal insulation paper on the market and the quality is also uneven. Therefore, when choosing thermal insulation paper, you must master certain product identification methods.

(1) Look at the clarity. The clarity of high-quality thermal insulation paper should be more than 6 meters at night, while the clarity of inferior thermal insulation paper is poor, especially at night, and the visibility on both sides and the rear windshield is unclear.

(2) Feel: High-quality insulation paper feels thick and smooth, while inferior film feels thin and brittle, wrinkles easily, and has poor explosion-proof performance.

(3) The color pigment of the product’s high-quality thermal insulation paper is dissolved in the thermal insulation paper. It is durable and not easy to change color. It will not discolor even if it is scraped with a scraper during the pasting process. Inferior thermal insulation paper usually uses dye. The color is in the glue. After peeling off the inner lining of the car film and scraping it with your fingernail, the color will fall off and the area where the film has been scraped by your fingernail will become transparent. During the film application process, when the film is scraped, sometimes the color will fall off on its own. This kind of insulation paper will change color in the same year, and the fading will be more obvious after one year.

(4) Bubbles: After tearing off the release film of the insulation paper and then laminating it again, the inferior film will bubble, while the high-quality film will remain intact after lamination.

(5) Thermal insulation performance is an important indicator of thermal insulation paper, which is difficult to identify with the naked eye and hand feel alone. It can be judged through a simple test method or comprehensive data from various data of thermal insulation paper: TSER, IRR, S.C, UV, VLT, etc.

3. A small method for testing thermal insulation paper.

Put a piece of glass covered with heat-insulating paper on a simulated solar lamp. If you can’t feel a trace of heat with your hands, it is a high-quality film, while if you feel hot immediately, it indicates that there is a problem with its thermal insulation performance and it is a low-quality film!

 UVC wavelength 100~280 nm. The shorter the wavelength of ultraviolet rays, the stronger the energy contained. The most harmful to the skin is ultraviolet C, but most of it is isolated by the ozone layer in the atmosphere. Only a very small amount reaches the ground. However, in recent years, the ozone layer With constant damage, the harm of UVC to the human body has gradually attracted people’s attention.

UVB wavelength 280~320 nm causes instant sunburn on the skin. Thickening, dullness, redness, eye inflammation, pain and dryness of the skin’s cuticles are mainly caused by UVB. UVB energy is stronger than UVA but easier to protect against.

UVA wavelength 320~400 nm More than 95% of ultraviolet rays are UVA, which has strong penetrating power and causes the greatest damage to the skin. And because it can directly reach the dermis, it promotes skin aging and increases melanin eye inflammation, which is the main factor causing spots. Frequent irradiation will cause the skin to relax, produce wrinkles, and cause capillaries to emerge, causing long-term, chronic and lasting damage. UVA can be subdivided into UVA-2 and UVA-1.

UVA1 has a wavelength of 320nm-340nm. It has deeper penetration than UVB and is more harmful to the skin. It can cause sunburn, redness and pain, actinic keratosis (age spots), and loss of transparency. Mainly UVA -1 caused by.

UVA2 wavelength 340~400 nm belongs to the long wave range, with the strongest penetration reaching the deepest part of the skin, reaching deep into the dermis to tan the skin. It is the most harmful to the skin, but it is also the easiest to ignore. Especially in non-summer UVA-1 intensity is weak but still exists, because the accumulated amount over a long period of time is enough to cause skin damage. Especially skin aging and sagging, wrinkles, loss of elasticity, melanin deposition, etc. are caused by UVA-1.
