UV glue, also known as shadowless glue or ultraviolet glue, is a one-component UV visible light curing modified acrylate structure glue. UV curing adhesive is composed of basic resin, reactive monomer, photoinitiator and other components, and is composed of stabilizer crosslinking agent, coupling agent and other additives. The following small series describes how to use uv glue and uv glue applications.
How to use uv glue
1. Surface treatment: According to the specific material treatment, the surface is dry and clean, with no weak boundary layer;
2, coated with UV glue: continuous coating of UV glue, do not disperse;
3, optical positioning: short-term low radiation, gently push by hand;
4, remove the overflow UV glue: knife scraping, soft cloth, paper towel gently remove the glue, you can lick acetone;
5, UV glue completely cured: high radiation for a long time, until completely cured, pay attention to the temperature should not be too high;
6, cleaning: soft cloth / paper towel, acetone, alcohol gently wipe;
Uv adhesive application field
1, in the application of medical supplies
Disposables have become one of the driving forces for the increase in the use of UV-curing adhesives. The technology has expanded to the use of a hypodermic needle attached to a syringe and an intravenous tube, as well as catheters and medical filters. The annual consumption of UV adhesives in this area in Europe is estimated at 20 tons, an annual increase of 5.4%.
2, in the glass and crafts, jewelry industry applications
The use of UV-curable adhesives has shown good momentum in other areas, including the use of kitchen windows and fittings in retail stores, building applications including stained glass, and, more importantly, the application of safety glass. The traditional process is to use polyvinyl butyral bonding, two layers of glass coated with this adhesive need to be rolled in a hot press, temperature 130 ° C, pressure 1.3MPa, and maintain a certain period of time. The total production time of this safety glass is about 20 hours. With UV-curing adhesives, the bonding process takes only seconds or minutes. This greatly shortens the production cycle, saves energy, and improves economic efficiency. In the jewellery and accessories industry, jewels, crystals and other mosaics and positioning can be quickly completed. Glass furniture is also an important application area, despite being influenced by fashion.
3, in the electrical and electronic industry applications
UV-curing adhesives are developing the fastest in electrical and electronic applications. The combined annual growth rate is an average of 9.2%. The estimated consumption has increased from 45 tons in 2000 to 70 tons in 2005. The main uses include:
1 Bonding and sealing of smart cards and conductive polymer displays;
2 Painting and sealing of terminals, relays, capacitors and micro-switches;
3 printed circuit board (PCB) paste surface elements;
4 printed circuit board integrated circuit block bonding;
5 coil wire terminal fixation and component bonding.
4, in the optoelectronics, information industry applications
Although the electrical, electronic, and automotive industries are the fastest growing segments, the largest consumer of optoelectronic information industry is the industry with huge potential, including three major consumer segments: digital disc manufacturing, optical fiber bonding, and liquid crystal and polymerization. Display.
Entering the information age, CD-ROM, as one of the most important information carriers, is in great demand and is expected to explode in the next five years. Whether it is now or in the future will be the largest application of UV-curing adhesives. CD, CD-R, and CD-RW are mainly used for the coating of a reflective film and a protective film. The larger amount is in the DVD manufacturing industry. There are two important points about DVD production: First, unlike its predecessor, the CD-ROM, its manufacture relies on the bonding of two layers of polycarbonate film to form a basic disk; secondly, Instead of sticking together at a point, the amount is increased. UV curing adhesives are also used for sealing covers for DVD packaging.
5, non-structural UV curing adhesive
The production of non-structural adhesives is relatively large. In 2000, it produced approximately 4,000 tons. The main types are pressure-sensitive adhesives and cardboard and packaging adhesives. Four good UV photosensitive tapes and labels for the market:
1 medical adhesive tape and repair medical pressure sensitive adhesive;
2 Dedicated engineering tapes, such as automotive and plumbing;
3 transparent film labels;
4 function tags.
Editor's summary: How to use uv glue and uv glue application field is introduced here, hope to be helpful to everyone. If you want to know more related information, you can pay attention to this website information.
