What are the functions of American Weibang building window film?

First, the function:

1, heat insulation against cold:

Weibang window film adopts a unique double-layer magnetron sputtering process to sputter highly reflective precious metals on both sides of PET substrate. In summer, far infrared (heat source) is blocked out to make the room cool; In winter, human body, household appliances, gas, etc. produce far infrared rays. Are blocked indoors, making it warm in winter and cool in summer, greatly reducing the electricity consumption of air conditioning and heating, and saving electricity bills. .

According to the national glass quality supervision and inspection center, sticking a layer of 0.05mm Weibang film on ordinary glass can effectively block about 50-90% of solar energy. In the experiment, under the irradiation of 250W infrared lamp, after 10mm seconds, 45℃ was detected on the back of ordinary glass and 25℃ was detected on the back of coated glass. After 30 seconds, the former reaches 54℃ and the latter is only 29℃.

2, explosion-proof anti-theft:

Weibang window film adopts high-purity PET synthesis technology (PET is a linear fiber resin with high toughness and heat insulation) to synthesize multi-layer PET. When encountering high-strength external force impact, micro-displacement will occur between multiple layers of PET, effectively dispersing external force. The pressure-sensitive adhesive layer on the surface of the film firmly adheres the film to the glass. Even if the glass is broken, Weibang membrane can fix it together to form a whole, resist the invasion of external forces and protect personal and property safety.

3. Bulletproof:

The thickness of Weibang bulletproof film is generally 0. 1mm ~ 0.4mm, which increases the number of layers and strength of PET on the basis of explosion-proof film. According to the inspection by the Security Police Electronic Products Quality Inspection Center of the Ministry of Public Security, sticking a layer of 0.4mm Weibang film on 10mm ordinary glass can block the penetration of Type 64 military pistol at any distance.

4, blocking ultraviolet rays:

Ultraviolet light is the chief culprit leading to fading and discoloration of furniture. According to the national glass supervision and testing center, the ultraviolet isolation layer of Weibang window film can block 99.8% ultraviolet rays, make your furniture and home decoration as new, and make your skin healthy forever.

5. Protect privacy:

Sticking a layer of Weibang one-way perspective film on the inside of the window can protect privacy, which will not affect the incidence of light, but also make the landscape outside the window clear and distinguishable, so that the line of sight outside the window can not peep into the private space inside.

6, decorate the home:

Weibang window film can effectively improve the architectural appearance, beautify the living environment and meet the visual aesthetic requirements of different consumers for living room decoration by using advanced coloring technology, styles and colors.

7, eliminate glare:

Nowadays, buildings use more glass than before, and the trend of open floor design, high ceiling and large-area glass application has become people's first choice standard. However, while glass brings beauty to the city, it also brings a lot of light pollution. Weibang film is helpful to correct the light intensity area and disperse the dazzling and uncomfortable glare.

1July, 970, in the east of Seattle, an important town in the western United States, the right corner of Boeing Aircraft Manufacturing Company, which previously provided riot prevention, heat insulation and cold protection services for Boeing's manufacturing workshops, assembly workshops and office buildings. Was officially listed. It is today's V-BEST company, which is well-known in Europe and America and the world.

After more than 40 years of international exploration and development, today's V-Best has formed a close partnership with dozens of crocodile enterprises or institutions around the world, and its products are sold to dozens of developed countries such as the United States, Britain, Germany, France, Japan and South Korea.

V-BEST has formed a global high-tech new thin film operation system integrating R&D, production, sales and promotion, with annual sales of functional thin films exceeding 500 million square feet. It has become a global supplier empire and global aerospace company with a full range of functional thin film products with the most advanced technology, nano-dense spraying, ceramic nano-spraying, magnetron sputtering coating and sandwich synthesis.

Second, the window film construction:

1. Building window membranes are mainly divided into privacy membranes, decorative membranes, heat insulation and energy-saving membranes, explosion-proof membranes and bulletproof membranes according to their functions, among which explosion-proof membranes and bulletproof membranes can also be classified as safety membranes. According to the production process, it is mainly divided into: dyed film, laminated film, primary color film and quantum film. Usually, the low-priced window film sold in the market is mostly dyed film, because it does not really have the function of heat insulation, energy saving and ultraviolet protection, and its service life is short, and it will fade and fall off after two or three years. Compound film is a kind of film plated on the basis of the original film. Compared with dyed film, it usually has a longer service life, but it will fade slowly with time.

2. Structure:

● One layer, transparent colloid protective layer

Second layer, pressure-sensitive adhesive layer

● Three anti-ultraviolet isolation layers

● Four layers, metal heat insulation film.

● Five layers and PET base layer

● Six layers and fixed adhesive layer

● Seven layers, wear-resistant coating.

3. Function:

Increase comfort

Nowadays, more glass is used in buildings than before. The application trend of open floor design, high ceiling and large area glass has become the first choice standard for people. But glass windows are an energy waste that everyone hates. It makes building owners and managers more and more worried about harsh glare, heat enhancement and high energy consumption. Working in the office or relaxing in direct sunlight at home can lead to fatigue, eye fatigue and distraction. Building film is a product directly installed on the inner surface of window glass, which is helpful to correct the temperature imbalance in strong light area or back sun area, dispel dazzling and uncomfortable glare, and make indoor employees more comfortable and efficient.

Reduce expenditure

The loss of heat through windows in winter not only makes people in the building feel uncomfortable, but also increases unnecessary energy consumption. Installing a solar control film with low emissivity on the inner surface of ordinary single-layer glass can reduce the heat loss by 30%. In summer, building film can block up to 79% of solar heat, thus reducing the cooling cost of buildings. Building film can reflect and absorb most of the solar infrared heat energy, and reduce the thermal conductivity of glass. Sticking the inner surface of the building membrane to the glass can prevent up to 82% of solar heat energy from entering the room.

Stop fading

Mid-ultraviolet radiation from the sun will lead to the fading of carpets, furniture, art paintings, curtains and chemical fiber fabrics, and also lead to skin cancer. Building window film allows visible light to enter, while blocking up to 99% of harmful ultraviolet rays. At the same time, it can also reduce the fading caused by visible light from the sun.

Add aesthetic feeling

Building window film can give the building a brand-new and unique appearance, and its cost is only a small part of other decoration expenses, and it will not cause inconvenience to indoor personnel migration. Deep dyed film, semi-reflective or total reflective film, rich colors and patterns provide a wide conceptual space for architects' design. From the inside out, the building membrane is comfortable and pleasant, blocking strong light and without scene deformation; From the outside to the inside, the appearance of the building membrane is consistent, adding beauty to the building; The translucent or one-way perspective film attached to the inside of your glass window can let light through, but it can block others' peeping eyes. There is also a new series of all-black film and matte decorative film for internal partition, which produces excellent results.
