With the rapid development of wireless communication in recent years, the styles of mobile phones are endless, not only are the functions more and more powerful, but the appearance is more and more sturdy, or dazzling, or refreshing, or clean, light, or elegant. Implied, very rich in texture, it is dizzying. These changes are due to the application of ultraviolet (UV) curable coatings in mobile phone production.

What is an ultraviolet (UV) curable coating?

Ultraviolet Curing Coating 1 (Ultraviolet Coating) is a UV-based coating, which is a new type of polymer environmentally friendly coating that uses UV light as a curing energy source to initiate chemical reactions between different components of a coating at normal temperature. The product does not contain organic solvents, the main components are polymer resins or monomeric lipids, and the coating film has no residual volatiles. Based on its unique curing mechanism and raw material characteristics, the products are characterized by non-toxic environmental protection, energy saving and high efficiency, wear resistance and scratch resistance, and extremely decorative effects. Internationally known as a new green environmental protection material for the 21st century.

Paying attention to environmental protection is a common trend in social development. In the United States, Germany, Japan, Italy and many other countries, legislation has adopted legislation to limit the use of traditional coatings with high VOC (volatile organic compound) emissions, and gradually replace traditional ones with new environmentally friendly materials such as UV coatings. product. On the other hand, due to its high efficiency and energy saving features such as fast curing and no need for heating and baking, it is very suitable for

Pipeline operations, the market's development is increasing at a rate of more than 25% per year. According to the prediction of Hess, Germany, by 2010, the production of solidified coatings worldwide will reach more than 20% of the total surface coating industry. It can be seen that UV radiation curing technology has been increasingly applied to the industrialized large-scale production of commodities, and its wide application has brought a new revolution to the entire surface coating industry.

 Keyboard? UV wear-resistant character ink

If the mobile phone is regarded as one of our partners, the mobile phone keyboard is the place we caress or tortures the most, especially the thumb family, who squats around their heads and squats, and is born as a mobile phone keyboard. Resist, put on the UV "vest" (wearing ink), and then cover the "UV super protective clothing" (special UV varnish).

Circuit board? UV electronic protective glue

As we all know, the circuit board is the core part of the electronic device, and its production is divided into two steps. First, the line is etched to etch the desired line on the copper film, and then the solder line is used to protect the copper line from being covered to prevent damage during component soldering. For extremely high precision requirements, the use of complex circuit boards, you can also solder all the electronic components with a layer of UV electronic protective glue, to be waterproof, dustproof and shockproof.

LCD screen? UV glue

The liquid crystal display can be roughly regarded as a layer of liquid crystal in the middle of two thin glass sheets. We may know that the liquid crystal is not heated and can not be contaminated. Only the UV glue is instantly cured and does not need heating and the ultraviolet light can pass through the glass. The characteristics can be applied to this requirement.

In addition, there are many places in the communications industry that use products based on UV curing technology, such as dyeing coatings for glass fiber filaments in communication cables, resists in semiconductors, photoresists, and so on.

Application of UV curing technology on mobile phones

From the advent of mobile phones, it has provided a unique opportunity for the unique advantages of UV curing technology. The market is full of various models of mobile phones, which are inseparable from the application of UV curing technology, in addition to the surface decoration of common mobile phone cases. In addition, the manufacture of high-precision circuit boards for mobile phones, the manufacture of liquid crystal displays, wear-resistant character inks for mobile phone keyboards, and the manufacture of semiconductors and communication optical fibers must be applied to UV curing technology.

Case surface? Special UV varnish

Undoubtedly, this is the most common and widely used place, and it embodies most of the unique advantages of UV curing technology. The UV varnish produced by UU curing technology can be completely completed in a few seconds to a second. Curing, the curing process does not require high-temperature baking, and it will not cause problems such as deformation of the casing, energy saving and high efficiency, and also reduce the scrap rate. The cured product has no volatile organic residues and is non-toxic and harmless. The workpiece after strong ultraviolet irradiation is also thoroughly sterilized. The gloss of the film can be adjusted from the highest light to the full matt, and with a variety of substrates and primers, it can produce a variety of surface effects. The entire coating is chemically reacted into a single unit that is extremely abrasion and scratch resistant. Several brands commonly used in the market include GOVE, Panstar, Musashi, etc., which are extremely excellent in surface gloss, fullness and texture.

Development of mobile phone-specific UV coatings

With the development of domestic UV coating applications and the market segmentation, a high-tech enterprise with the goal of “professional UV curing technology in high-end fields such as communication and electronics” has emerged. GOOF o

Since the project was launched in 1999, the high-level domain (DOVE) has produced a clear-cut slogan. Since 1998, the researchers have been paying attention to the application prospects of technology in the fields of communication and electronics, and have established close technical cooperation relationships with many famous universities and chemical research institutes at home and abroad, bringing together digital experts and technologies in the field of UV curing. The latest research topic of the elite, through the project feasibility survey in 1998, the same year began the development of high-precision multi-layer circuit board photosensitive etching oil and solder resist oil, in 1999 began the development of silver surface UV varnish and UV electronic protective adhesive, In China, it successfully developed the special wear-resistant UV oil for silver powder foundation, the special wear-resistant character ink for keyboard, the special shadow mask varnish for keyboard, etc., and then successfully developed UV electronic protective glue for communication, high-precision multilayer circuit. Plate photosensitive line ink, solder mask ink and other products, product performance has reached the international leading level by national testing, and successfully entered the various fields of application in the communications and electronics industries. With its low-key and steady behavior and attention to quality and technology, Dove has become a prominent player in the domestic UV industry and has become a representative of high-quality UV suppliers in the communications and electronics industries.
