A review of reflective films for reflective films, the role of reflective films

<>1. Increase the light intensity in the shed, which has a good effect of supplementing the light. 2. Increase the temperature in the shed, which will affect the local air temperature and ground temperature. 3. Shorten the seedling time, shorten the seedling time, improve the quality of seedlings, and reduce the node position of female flowers.

4. Reduce the amount of pesticides, increase the light and temperature, improve the climate in the shed, enhance the disease resistance of the plant, and reduce the use of pesticides and pollution. 5. Increase economic benefits, increase output and increase output value.

Summary. Thank you for your patience, the difference between pro-reflective film and normal film is that reflective film has the ability to reflect light, while normal film does not. As a result, the reflective film can reflect some of the sun's rays and lights, reducing the temperature and glare in the car, and improving driving safety.

Ordinary films, on the other hand, only have the functions of privacy protection and shading. In addition, the reflective film will be higher than the ordinary film**. I hope mine is helpful to you, can you please give a like (rate it in the lower left corner), thank you

Thank you for your patience, the difference between pro-reflective film and normal film is that reflective film has the ability to reflect light, while normal film does not. Therefore, the reflective film can reflect part of the sun's rays and lights, reduce the temperature in the car and reduce glare, and improve driving safety. Ordinary films, on the other hand, only have the functions of privacy protection and shading.

In addition, the reflective film will be higher than the ordinary film**. I hope mine is helpful to you, can you please give a like (in the lower left corner of the rental center to evaluate Oh), thank you

The difference between metal reflective film and ordinary film.

The difference between metallophilic reflective film and ordinary film is that the material is different. Metal reflective film is composed of metal film and polyester film, while ordinary film is usually polyester film or fluorocarbon resin film. Due to the metal reflective film, Lu Yan has a stronger ability to reflect silver light, which can reflect more sunlight and car lights, so the effect is better, but it may produce visual interference of metal reflection.

The reflective ability of ordinary film is weak, but it will not produce reflective visual interference, and the light transmittance will be better. In addition, the metal reflective film will be higher than the ordinary film**.

Reflective film is used in a wide range of applications, including highways, aviation, railways, shipping, automobile license plates and other fields, made from it.

Traffic signs reflect bright and clear light when illuminated at night, so that the envoy or other personnel can see the security police clearly.

Notices or prohibition signs play an increasingly important role in ensuring traffic safety. In addition, in recent years, it has been more and more widely used in fortification boards, billboards, street signs, street signs, etc.

1: The application of reflective film in highway traffic signs: different grades of highways, according to the different design speeds, the use of different levels of reflective film to make signs, usually the design of faster roads (such as highways, expressways, highways, etc.) stipulates the use of reflective film with high retroreflective coefficient and strong reflective brightness; Recently, some economically developed areas and urban roads have also designated the use of high-grade reflective film to make road signs, which is not only beautiful but also improves safety performance; Usually, roads with slower design speeds (such as provincial roads and national highways) use more medium-grade reflective films; And some temporary signs, usually use low-grade reflective film.

2: The application of reflective film in automobile license plates: the number plate used on vehicles in mainland China is a ninety-two type license plate, which is born.

The production process is 1) paste a reflective film with good flexibility on the aluminum plate (usually using a license plate-level reflective film), and use a special machine.

The device stamps out the number, and then silk-screens the color on the number, such as the license plate is black on a yellow background, then use the yellow reflective film to screen black oil.

Ink, the process of processing the license plate for the word non-reflective brand reflective, usually after a period of use, often appear ink off, whole.

The block license plate becomes a color, and the license plate of Guangdong Province is made using this process; 2) Paste the aluminum plate with good flexibility.

Reflective film (usually use license plate-level reflective film), and then silk screen, such as the license plate is white on a blue background, use blue with white reflective film.

Color ink silk screen, and then stamping out the number, with the day that the ink on the number is wiped off, the process of processing the license plate word reverse.

The light plate is not reflective, and the license plate of Hunan Province is made using this process; In 2002, the 02-type personalized license plate was launched, when it was in Beijing

Tianjin, Shenzhen, and Hangzhou were launched as pilots, and the process was completely different, and the pilot was stopped for various reasons after half a year.

3: The application of reflective film in the body logo: "2004 police car special logo" is made of reflective film screen printing;

The relevant departments of the state mandate that the body of a truck that reaches or exceeds a certain weight must use a reflector to show the contour of the vehicle;

Vehicles transporting hazardous chemicals must be labelled with a special label made of reflective material.

4: Application of reflective film in other fields:

1. Body sticker.

2 Equipment & Safety Signage.

3. Signs, street signs, factory indication systems, house numbers.

4 Advertising and Industry Logos.

5 Public Welfare Signs.

With the continuous improvement of people's living standards, the demand for individualization has increased sharply, and the application fields of reflective materials are becoming more and more extensive.

Reflective materials are mainly used to make all kinds of reflective signs and signs, DU vehicle number plates, safety facilities, etc., in the daytime with its bright colors play an obvious warning role, at night or in the case of insufficient light, its bright reflective effect can effectively enhance people's ability to identify, see the target clearly, cause vigilance, so as to avoid accidents, reduce personnel, reduce economic losses, become an indispensable safety guard of road traffic, has obvious social benefits. The scope of use is widely involved in public security transportation, traffic supervision, fire protection, railway, coal mine and other departments, and civil reflective materials are mainly reflective cloth, reflective lattice sheets, reflective inkjet cloth, etc.

The use of high-frequency vibration waves to transmit to two or more material surfaces to be embossed, in the case of pressure, so that the surface of the material rubs against each other to form a fusion between molecular layers, its advantages are fast, energy-saving, high fusion strength, good conductivity, no sparks, close to cold processing.

Features:1The embossing time is short, the ultrasonic automatic embossing, and the width is determined by the customer;

2.Embossing eliminates potential safety hazards and belongs to a new generation of safe and environmentally friendly products;

3.The embossing is clear, the surface is more three-dimensional relief effect, and the product is more high-end and beautiful;

4.After processing, the finished product has no pinholes and no water seepage, which is more waterproof and ambiguous;

5.Using roller mold, it is easy to change the mold, and can stitch out the ever-changing and complex discontinuous and symmetrical patterns, and can develop various flower patterns according to customer needs;

6.The machine has a high degree of automatic intelligence, and the assembly infrared automatic edge alignment system can automatically correct the materials of each layer, so that the upper and lower materials are always aligned during stitching, the processing loss is low, and the product is more flat and stable.

The working principle is to make the reflected light return to the light source from the opposite direction close to the incident light through its functional unit.

The reflective film is composed of multiple film layers, including a weather-resistant surface layer (such as acrylic, PET, etc.), a functional layer, an adhesive layer (including pressure-sensitive adhesive and release material), and there may be several auxiliary functional layers according to the actual situation.

The functional layer is the core unit, which has two different types: glass bead type and micro-prism type, and the design of the unit involves multiple disciplines such as optics and chemical engineering.

For details, please refer to GBT18833-2012 road traffic reflective film

Reflective film is a special structure of PVC film that can reflect light back to the light source by using optical principles. It is composed of a thin film layer with good weather resistance, a micro glass bead layer, a focusing layer, a reflective layer, an adhesive layer and a peeling layer. It is widely used in the road traffic sign manufacturing industry.

Back to the principle of reflection! It's the light that comes from there and goes back there. This is achieved by means of glass beads or microprisms.

To be studied by classification. There are many ways to classify reflective films. Among them, the more commonly accepted classification principle is based on the basic structure of the retroreflective unit, and the ranking method is based on the retroreflective coefficient of the photometric performance of the positive photometric performance of the reflective film.

However, considering the different processes of reflective films, some are specifically designed to solve the non-positive retroreflective brightness, some are designed to take into account both performances, and some are aimed at the visual recognition needs under harsh climatic conditions, so this classification method also has shortcomings. Therefore, it is necessary to be familiar with and master the application conditions and design functions of various reflective films. In the traditional habit, according to the structure of the reflective film reflective unit, the reflective film is divided into two categories, glass bead reflective film and micro prism reflective film.

Each type of reflective film also contains many types, such as micro-prism type reflective film, due to the use of more advanced technology, its material selection and prism structure, there are many changes, can cope with more traffic needs. According to the form and technical characteristics of prisms, micro-prism reflective film can be divided into truncated prism reflective film with good long-distance retroreflection ability, truncated prism reflective film with good close-range large-angle retroreflection performance, and full-prism reflective film that takes into account the needs of all aspects, fluorescent full-prism reflective film with good performance during day and harsh climatic conditions, and prism-type reflective film that meets the traditional engineering-grade retroreflective parameters.

It's a reflective material. Reflective materials, also known as retroreflective materials, are widely used in various road traffic safety facilities such as traffic sign markings, protruding road signs, contour signs, traffic cones, anti-collision cylinders, as well as car license plates, clothing, shoes and hats, fire protection, railways, water transportation, mining areas, etc., which can be divided into traffic sign reflective materials, road marking reflective materials, protruding road signs, contour signs, reflective materials for clothing, etc. The realization of the retroreflective function of light is achieved through various reflective materials with retroreflective properties, most of which are not naturally formed in nature, but rely on human creativity to invent and synthesize new substances the day after tomorrow.

Retroreflectance technology brings together a variety of disciplines and technologies such as optics, materials science, mathematics, organic chemistry, etc. According to the principle of retroreflective, reflective materials can use the illumination of the lamp and the reflection of light to "light up" the front, improve the distance of the driver to find the object in front of him, so as to give the driver more time to take corresponding safety disposal measures. Compared with other types of road traffic safety measures, the application of retroreflective technology is undoubtedly a low-cost and effective solution compared to the cost of various road traffic accident injuries.

In a sense, the application of retroreflective materials is a more proactive safety precaution, which is more safety valuable and more caring for life than measures aimed at reducing the degree of injury after an accident, such as guardrail protection. Figures 1 and 2 show the various typical applications. Since the 30s of the 20th century, in addition to the rapid use of various new retroreflective materials created by the science and technology industry to reduce road traffic injuries as soon as possible, human beings have also begun to gradually start the research on the application of retroreflective technology to improve road traffic safety conditions.
