How to use uv glue
1, surface treatment: according to specific materials, the surface is dry and clean without weak boundary layer;
2, coating UV glue: continuously coating UV glue without dispersion;
3, optical positioning: low radiation for a short time, and can not be pushed by hand;
4. Remove the spilled UV glue: scrape it clean with a knife, gently wipe off the spilled glue with a soft cloth and paper towel, and dip it in acetone and alcohol;
5, UV glue completely cured: high radiation for a long time, until completely cured, pay attention to the temperature is not too high;
6. Cleaning: gently wipe the soft cloth/paper towel with acetone alcohol;
Uv glue application field
Application of 1 in medical supplies
Disposable products have become one of the driving forces for the increase of ultraviolet curing adhesive consumption. Technology extends to the combination of hypodermic needles with syringes and intravenous tubes, as well as the use of catheters and medical filters. The annual consumption of UV adhesives in this field in Europe is estimated to be 20 tons, with an annual growth rate of 5.4%.
2. Used in glass, handicrafts and jewelry industries.
The amount of UV-curable adhesive has a good growth momentum in other aspects, such as the decoration of kitchen windows and retail stores, architectural applications including stained glass, and more importantly, the application of safety glass. The traditional process is to bond with polyvinyl butyral. Two pieces of glass coated with this glue need to be laminated on a hot press for a certain period of time under the pressure of 130℃ and 1.3MPa. The total production time of this kind of safety glass is about 20 hours. With the help of UV curing adhesive, it only takes a few seconds or minutes to complete the bonding process. This greatly shortens the production cycle, saves energy and improves economic benefits. In the jewelry and decoration industry, you can quickly set and locate gems and crystals. Glass furniture is also an important application field, although it is greatly influenced by fashion.
3. Applications in electrical and electronic industries
The application of UV-curable adhesives in the field of electrical appliances and electronics is the fastest, with an average annual growth rate of 9.2%. The estimated consumption increased from 45 tons in 2000 to 70 tons in 2005. Its main uses include:
① Bonding and sealing between smart card and conductive polymer display;
② Painting and sealing of terminals, relays, capacitors and microswitches;
(3) printed circuit board (PCB) surface components;
(4) bonding an integrated circuit block on the printed circuit board;
⑤ Fixation of coil terminals and bonding of parts.
4. Application in optoelectronic and information industries
Although the electrical appliances, electronics and automobile industries are the fastest growing sectors, the optoelectronic information industry with great potential is the biggest consumer, which mainly includes three consumption areas: digital disc manufacturing, optical fiber bonding and liquid crystal and polymer displays.
In the information age, as one of the most important information carriers, the demand for optical discs is amazing, and it is expected to explode in the next five years. Whether now or in the future, it will be the largest application field of ultraviolet curing adhesive. In the manufacture of CD, CD-R and CD-RW, it is mainly used for plating reflective film and protective film. The larger quantity is in DVD manufacturing, and there are two important points about DVD production: first, unlike its predecessor CD, its manufacturing relies on two layers of polycarbonate films to form a basic disk; Secondly, it is not through the point but through the surface, which increases the dose. In addition, the sealing cover for DVD packaging also uses ultraviolet curing adhesive.
5. Unstructured UV curable adhesive
The output of unstructured adhesives is relatively large, about 4000 tons in 2000. The main types are pressure-sensitive adhesive, cardboard and packing box glue. Four markets of UV photosensitive tapes and labels with good finished products;
① Medical adhesive tape and medical pressure-sensitive adhesive for repair;
(2) Special engineering tape, such as automobile and pipeline industries;
③ transparent film label;
④ Function label.
