What are the characteristics of UV curing? What is light curing? Light curing technology is an efficient, environmentally friendly, energy-saving, high-quality material surface treatment technology, known as a new technology facing the 21st century green industry. At the International Conference on Radiation Curing in North America held in Charlotte, USA in May 2004, light curing and electron beam curing technologies were summarized as "5E" industrial technologies: efficient (efficient); enabling (wide adaptability); economic (economic); energy saving (energy saving); environmental friendly (environmentally friendly).

 

 

 

1. Efficient:

 

 

 

Common UV coatings, UV ink and UV adhesives for UV curing products. They are characterized by fast curing rate, usually in a few seconds to tens of seconds, fast curing time in 0.05-0.1 seconds, is currently a variety of coatings, inks, adhesives drying curing speed. If the UV optical fiber coating has reached 1500-3000m/min, the UV offset printing ink can also adapt to the printing speed of 100-400m/min, which can meet the production requirements of large-scale automation pipeline, greatly improve production efficiency, and save the space for semi-finished products stacking. The drying and curing time of solvent-based or thermosetting coatings, inks and adhesives usually takes hours or even days, and a large workshop is needed to stack semi-finished products.

 

 

 

2. Wide adaptability

 

 

 

Light curing products can be used in many kinds of substrates, such as paper, wood, plastics, metals, leather, stone, glass, ceramics, etc., especially for some heat sensitive materials (such as paper, plastics or electronic components).

 

 

 

3. Energy saving:

 

 

 

The UV curing product is fast curing at room temperature, and its energy consumption is only 1/10-1/5 of that of the heat curing formulation product. Light curing only needs radiation energy to stimulate photoinitiator, and does not need to heat the substrate, material and surrounding space as heat curing does. It also needs to evaporate the dilution solvent or water, which consumes a lot of energy.

 

 

 

4. Environmental friendliness

 

 

 

Another advantage of UV-curing products is that it does not contain volatile solvents. Active diluents used are high boiling point organic compounds, multi-functional acrylic monomers, and they all participate in cross-linking polymerization when curing. They become part of the cross-linking structure, so they do not cause air pollution and reduce the harm to human body. Fire hazard is a kind of environmentally friendly product.

 

 

 

5. Economy

 

 

 

The production efficiency of UV curing products is high and the energy consumption is low; moreover, the investment of UV curing equipment is relatively low, and it is easy to realize pipeline production. The workshop occupies a small area, which can save a lot of investment; it does not contain solvents, reduces pollution, and saves resources. Comprehensive consideration is economic.

 

 

 

With all kinds of attention to environmental protection and strict legislative restrictions on VOC emission from the atmosphere, the advantages of UV curing products become more prominent. The United States, Europe, Japan and other developed countries will use UV curing technology as one of the important means to reduce VOC emissions.

 

 

 

The advent of UV LED has brought revolutionary changes to the UV curing industry. It has the characteristics of constant illumination intensity, temperature control, portability and environmental protection, relatively low purchase cost and almost zero maintenance cost, which promotes the quality improvement and energy saving of UV curing process.

 

 

 

Light curing technology has been widely used in printing, packaging, advertising, building materials, decoration, electronics, communications, computers, household appliances, automobiles, aviation, aerospace, instrumentation, sports, hygiene and other fields due to its advantages of fast curing, high production efficiency, energy saving, environmental protection, high quality, economy and suitable for a variety of substrates. All walks of life. We believe that through the joint efforts of the whole industry, the future UV curing industry will have a new world of environmental protection and energy saving.
