1. Introduction
Glass coating
Glass coating can block the summer 45-85 percent heat of direct sunlight into the room, can be reduced 30% or more in winter heat losses; when the glass when broken, glass fragments can be firmly attached to the film surface, to maintain the original shape, and no splash, no deformation; and the glass film able to withstand temperatures up to 500 degrees, the fire can be effectively prevented, to avoid harm to human body, mass good glass film can block ultraviolet glare and 99 percent.
effect
window film has been quite popular in foreign countries, while in China, building utilization rate is still very low, as a new type of energy-saving building materials, glass film has seven major advantages: 1, insulation, thermal insulation; 2, safety explosion-proof; 3, UV protection; 4, anti-harsh glare; 5, easy to create a private space; 6, enhanced visual effects; 7, high temperature fire; the seven advantages of people’s daily lives in , window film to play a very useful, it is precisely because of these advantages, it has been more and more of people’s preferences and praise, widely applied to the majority of people’s lives go; in general, films are attached to the glass inward, so that life can be extended. Minimalist decor favorite, it is translucent and hazy, full of infinite expansion of space and reality separate block, has replaced the traditional decoration style, either make a good indoor natural light and can reduce visibility. It is rich in color, style transformation flexible, creative real simple, low cost, safety and environmental protection, has become the best choice for personal privacy of homes, offices, restaurants, shopping malls reception, as well as bedroom and bathroom.

1, more economical. Upgrading the existing ordinary were hollow glass paste or a heat reflecting coating is a low emissivity film: both tempered glass transparent glass or colored reflective film than the thermal paste to replace the heat reflecting glass 50 for a total cost savings percentage of the remaining cases by analogy, e.g. hollow glass or a heat reflective coating hollow low emissivity coated glass.
2 faster. Remove the old window film than both glass and then put the new glass short duration, easy to operate.
3, more environmentally friendly. Replace the glass cullet will generate a lot of construction waste, transportation and landfill costs will increase, and the glass film can be used both to make insulation and safety upgrades. But also to prevent indoor carpet, curtains, fabric and paint fading, the effective protection of indoor furniture, computers and other office equipment, extending its life.
4, more secure. The insulation film is generally also have some security enhancements, and includes a clip (plastic) viscosity glass debris layer holding performance which is superior to safety glass, security professional security film stronger.
5, more healthy. Mounting the laminated glass film containing UV (ultraviolet) absorber, the barrier 98 may be an ultraviolet percentage -99 percent.
6, more lightweight. If replaced hollow glass or hollow LOW-E glass, part of the total weight of the added hollow glass two double or more, will greatly increase the constructionBuilding load. Film industry in China has more than 10 years time, if investors need to be cautious industries. The method
3, identification
Glass coating
differentiate genuine glass film glass film:
1 nasal smell. Inferior film pressure-sensitive adhesive commonly used, which contains a large number of plastic molecules benzaldehyde, odor volatilized in the sunlight, while the specific vehicle installation plastic film is almost no taste.
2 hand touch. Quality thick film feels a sense of smooth, low-quality thin film is very soft, the lack of adequate toughness, but also easy to wrinkle.
3. Seeing. High resolution quality explosion-proof membrane, regardless of color depth and perspective properties are good, but inferior film color unevenness.
4. Rubbing alcohol, gasoline, cleaning agents Chemicals asphalt. Since only a poor quality film dyed glue, or only the adhesive layer coated at the UV agent, the resist film is removed after wiping layer, you can see bleaching, or by an instrument testing, was found to significantly reduce the UV. The anti-scratch. High-quality film at normal lift windows surface of the film will not be scratched, fameng, poor quality automotive film in this area, there are obvious flaws.
6. Warranty card. Only the manufacturer warranty card film is trustworthy manufacturers warranty card usually contains warranty program, age, payment methods, and true to be found in the manufacturer’s name, address and telephone number.
7 Technical parameters. Visible light transmittance, heat rate, UV blocking rate is used to reflect the performance of the membrane manufacturer professional terms, the relationship between the three is generally: the transparent film, the lower the heat insulation; the reflective film, heat insulation higher. Measuring instrument available to consumers store to see if close to the nominal technical parameters.
8. Whether the sale of products and packaging materials have the original manufacturer’s detailed product type, address, phone number, website, bar code. Also see if you are using the original unified promotional identity, authorized dealers in order to use all propaganda identify the original, otherwise will be chasingStudy tort liability; depends on whether there is a valid marketing authorization certificate.
4, the principle of
glass film structure, performance and other principles: the basic film composition is: a polyester substrate (PET), one surface coated with anti-scratch layer (the HC), the other side subbing layer and the protective film is mounted. PET is a strong a durable, rugged and resistant to moisture, resistant to high and low temperature resistance are good material. It is clear, by a variety of metallization layer treatment process, magnetron sputtering, dissection of, a film having different properties. Professional film manufacturer typically use viscose for each Pat dissection and mounting adhesive layer. Divided into: pressure-sensitive adhesive and water molecules activated glue. Architectural glass film is divided into two series: solar film and safety film.
The main varieties are: transparent heat mirror, reflecting heat insulation film, a low reflective insulation, low emissivity (Low-E) film, and a frosted translucent decorative film, a transparent safety film. Glass is generally a single layer or a multilayer film PET dissection, there thickness: 2MIL (0.05mm), 4MIL (0.10mm), 7MIL (0.18mm), 11MIL (0.28mm), 14MIL (0.36mm) and the like; in view of safety ease of construction, the film thickness of the substrate should be 2MIL above. The method of installation is generally similar to the film, i.e. after removal of the protective layer, a subbing layer is mounted on the mounting surface of the liquid sprayed clean glass surface and the film; film plated on the glass edges cut off the excess, with the installation tool remove excess water and so on.
5, the application of
In recent years, as the Chinese government have to pay attention to energy conservation, window film has been very popular have been applied to many famous buildings which, summed up can be divided into: 1 the glass film glass film used in commercial buildings with paste to the glass surface so that uniform and harmonious space, to prevent accidental breaking glass splash while more effectively blocking heat radiation, to reduce air conditioning costs, safety and energy saving best of both worlds. Fashion style and soft feeling through crystal clear with perfect one, canFor the building to create a light and spacious and has a very changing fashion business space.
2.

6, the parameter
Glass film solar transmittance Total Solar Transmittance (TST) – the percentage of solar energy through glass film; Solar Reflectance Total Solar Reflectance (TSR) – the percentage of total solar energy reflected by the glass film; solar absorptance Total Solar Absorption (TSA) – percentage of total solar energy absorbed by the glass film; visible transmittance Visible Light Transmittance (VLT) – directly through film the percentage of visible glass; visible light reflectance of visible Light reflectance (VLR) – the percentage of visible light reflected from the glass surface of the foil; ultraviolet baffle of UV Radiation Transimittance (URR) – percentage of total solar ultraviolet transmission of the glass film; sun shield factor Shading coefficient (SC) – the percentage of the total film solar transmittance; U- value Winter Median “U” value (U value) – Fahrenheit loss of BTU per hour per square meter as measured by a glass film; tensile strength tensile strength – tensile force per unit sectional area of the film at the tensile fracture required, given unit pounds per square inch; breaking strength breaking strength – tensile force per unit width of the film when the film breaks required, given units per square inch pounds; puncture strength puncture strength – dedicated experiment The force needed to pierce the film, given units per square inch pounds. Peel strength– peel strength per unit width of the film to force 90 or 180 degrees required for peeling from the glass surface, a given unit pounds per square inch; elongation at break Fracture elongation– for tensile test, the film breaks , percentage increase in length of the film; heat shielding coefficient (SC) – ordinary 3mm clear float glass carrier is detected, the film solar total solar energy transmittance (1- heat rate) and the total transmittance of the film is not ( the ratio is generally between 83-88 percent); “U” value (U value) – when referring to indoor and outdoor temperature 1 ℃, heat 1 ft2 ordinary clear float glass within 1 hour through. The lower the U-value, the less heat transfer, the better the insulation effect; which English units of measurement are: BTU / h · ft2 · ℉ (EnglandMeasurement thermal units / hr ft² Fahrenheit) units of the metric is: W / m · deg.] C (W / m · centigrade) shield shading coefficient (SC) can verify total solar energy blocking rate (TSER), i.e. “heat rate” of the true extent is a measure of the parameters of daylight window heat control, the lower the coefficient of thermal shielding on behalf of its thermal control the better. The SC = 0.5, the heat rate should be truly reflective proof membrane is about 55 percentage; all indicators: visible light reflectance (VLR) + total solar absorptance (TSA)> total solar energy blocking rate (the TSER) ultraviolet screening rate (ultraviolet Rejected): glass through the solar ultraviolet (300-380 nm) and the emission ratio of the total solar ultraviolet rays on the glass system. UV is the main factor leading to the solar spectrum textiles and furniture fading deterioration, exposure to the skin can cause injury. The visible light transmittance (Visible Light Transmittance): glass transmits visible light (380-780 nm) and the total visible light emitted on the glass surface, expressed as a percentage accessible, formed mainly affected by the harsh glare visible light transmittance. Heat: conducted to the heat and infrared filters to remove by the reflection layer, reducing the heat transfer chamber, so as to effectively reduce the room temperature, energy-saving air conditioning power. Way perspective: in strong outdoor light can not see at the scene at the indoor low light, that is not clear indoor outdoor, indoor and outdoor can clearly see the scene. At home wearing free life, to protect the privacy of the room. Explosion: outdoor effective against violence against impact, prevent intrusion, to prevent the glass burst fall injury. Bulletproof: Special anti-riot products with super ability, and even anti-bullet pistol shooting (Ministry of Public Security test report).
7, Category
Glass coating
Glass coating according to their functions and applications are divided into three categories: EEB film, security film, and chamber decorative film. Building energy conservation film, suggests that it is used in residential, office buildings, commercial buildings and other architectural glass doors and windows, glass curtain wall, through solar control, improve the indoor environment, reduce cooling energy consumption for heating, so as to achieve the effect of energy-saving glass film. Which are widely used in home, office, leisure and other places. In the summer, PAN Rong insulation film, Wisdom Bekaert, super film, Sen Jia films, 3M, Johnson & Johnson film, Wei solid film, Sen cool film, LLumar energy-saving films block up to 79 percent by solar thermal energy, can greatly reducing the cost of air conditioning refrigeration; winter, indoor heat loss through the window, not just the person in the room to feel unwell, and adds unnecessary energy costs. The inner surface of the glass film is attached to the energy ordinary glass heat loss can be reduced by up to 30 percentage, so as to achieve the role of warm in winter.
Development of a glass film, glass film for improving the energy efficiency of the application of ordinary glass security can be traced back to 1960. Development of the film was the original intention, in order to control the heating when the solar load caused by uneven cooling, the film has only the early solar radiation reflecting glass window, to prevent the heat within the glass surface of the increased performance. With the continuous development of the manufacturing process, a new generation of body-tinted window film was born, its rich colors provide a broad design space for architects. The main colors: brown, gray, gold, amber, blue, green and so on. US energy crisis of 1970 leads to another aspect of the development of film properties to reduce indoor heat loss (i.e., “insulation.”) Found that, not only the polyester film as the transparent medium, and more capable of absorbing the long-wave infrared radiation inverse . After repeated tests. Material of the membrane, the structure has a large change, but also improve the “insulation” film also produced a “low emissivity film” LOWE film. The basic film constituting the substrate is polyester (PET), one surface coated with anti-scratch layer (SR), the other side adhesive layer and the protective film is mounted. Mounting construction, the protective film is peeled, the exposed side of the adhesive layer is affixed to the inner surface of the glass (if it is particularly designed for the outer film paste, the paste with the outer surface of the glass) the PET is a strong a durable, rugged, high toughness, moisture resistance, high resistance, low temperature resistance are excellent materials. It it clear, transparent mass dyeing, the metallization layer, magnetron sputtering, and other processes dissection treatment, a film having different physical properties to accommodate different commercial buildings, residential, shop windows, bank counters, car or ship need places. The main building is divided into two series with the film to the glass: building energy-saving films and security films. The main varieties are: a body membrane staining, heat reflecting insulation film, insulation film of low reflection, high transmittance films magnetron sputtering, low emissivity (LOW-E) film, museums and archives for film, matte and semipermeableThe decorative film, a transparent safety film. Four basic characteristics: energy-saving insulation, UV resistant, beautiful and comfortable, safe and explosion-proof. Film to the glass in the construction industry can be called: “amphibious” products, which made both for the renovation of old buildings, can also be used for new building.
8. Interpretation
Title: Glass coating Pinyin: bolitiemo English: glassfilms meaning: the film attached to the glass surface, where the glass can have some special effects.
9, maintenance and repair glass film
First, the window film 3 days after installation, do not move the glass.
Second, the window film 15 days after installation, do not scrub water glass film.
Third, the glass film is suspended or unavailable chuck fixing any article with adhesive, self-adhesive decorations can not stick window membrane.
Fourth, the ammonia-component cleaning agent uniformly sprayed slightly window membrane, followed by clean, soft tissue or soft cloth gently dry glass, cotton and paper towels are often required to wring, comprising pure rubbing alcohol on a cotton cloth / paper towel will soon dissolve huge fingerprint smudges and greasy. If the stain is not washed, the washing liquid is sprayed again, the horizontal wipe from top to bottom with soft rubber wiper scraping window membrane until it is dry. Towel dry the edge of the glass film.
Fifth, glue or adhesive residue due to the time window membrane using an adhesive tape, decal, or when the card, to remove these materials, can be used soft clean cloth dipped in acetone gently scrub the contaminated areas, can quickly remove these residues completely viscose on the glass film, a small amount of acetone polyester film is not damaged, but it can immediately dissolve the adhesive and most complete evaporation and spray .
VI erasable not use rigid plate, a brush, cloth cleaning sand containing glass film.
