What is Ultraviolet (UV)?2022-03-27T22:39:29+03:00

Ultraviolet or ultraviolet radiation (UV for short) is light with a wavelength between 100 and 400 nm.

How much of the UV rays can the eye see?2022-03-27T22:35:58+03:00

Our eyes are sensitive to wavelengths between 400 and 700 nm. And it cannot detect any radiation other than that. We perceive the smallest wavelength radiation we can see as ‘purple’. Therefore, the light with a wavelength smaller than this is called “ultraviolet radiation”. Beyond the Ultraviolet is the X-Ray.

How are UV rays classified?2022-03-27T22:36:55+03:00

Scientists have divided UV rays into three categories as UV-A, UV-B and UV-C, since they do not have the same characteristics and their effects on living things are different.

What are the classes of UV rays?2022-03-27T22:41:03+03:00

UV-A: They are the most common rays. It is the most common with 95% of UV rays. The ozone layer allows these rays to pass through.
UV-B: It is quite dangerous. Most of these rays are blocked by the ozone layer. It makes up 5% of UV rays.
UV-C: These are the most dangerous rays for health. The ozone layer prevents these rays from reaching us.

What is UVA Sterilization?2022-03-27T22:42:06+03:00

UVA Sterilization is the “slow” process with 390 to 405 nm light. While UVC is broken down to 10 and sterilization is provided, sterilization with UVA provides the disinfectant effect of the sun. A light with a wavelength of 390-405 nm initiates a ‘reactive oxidation reaction’ on organic surfaces and acts by destroying the cell membrane.

It has been reported that this oxidation is also effective in some viruses. The weakness of this method is that its effect is very slow. Although it varies according to the application area and the power used, it can take 3 to 5 days to achieve 99% sterilization on the surface. It is more successful in ensuring the continuity of the sterile environment after disinfection with chemicals or other methods.

Usage power should be selected according to the area used. For example, Staphylococcus Aureus bacteria die 99.9% in 75.3 hours when 70W UVA is applied in 50m2 area from 2.5m height.

What are the Uses of UV?2022-03-27T22:45:03+03:00
  • Food industry,
  • Cosmetics industry,
  • Pharmaceutical industry,
  • Dialysis machines,
  • Mineral water or natural spring water bottling facilities,
  • UV systems are often used to prevent bacterial growth on membranes.
  • UV systems are often used in hot water lines.
  • Against some parasites that have gained resistance to chlorine, a UV device can be used in addition to chlorination.
  • UV systems are used in the disinfection of wastewater.
Why Are Offset UV Dryers Used?2022-03-27T22:46:17+03:00

Offset UV dryers are used for drying after printing with UV Ink and UV Lacquer in offset printing machines of different models and sizes.

Why are the Silk Screen UV Dryers Using?2022-03-27T22:47:33+03:00

For drying the prints made with UV Ink and UV Lacquer, Serigraph UV dryers are used in hand looms of different models and sizes, semi-automatic or fully automatic silk screen printing machines.

How Do Label UV Dryers Work?2022-03-27T22:48:17+03:00

For drying the prints made with UV Ink and UV Lacquer, Label UV dryers are used in various models and sizes of printing machines such as Flexo, letterpress, which work from reel to bobbin.

Label UV dryers also provide solutions with different power and number of lamp applications depending on the speed of the printing machine and the characteristics of the material applied to the printing.

What are the Usage Areas of Roller Coater?2022-03-27T22:49:13+03:00

It is designed for all kinds of paint and varnish applications on flat surfaces.

It is applied with a roller system on the flat surfaces of MDF, chipboard and plywood plates, parquet, door panels, cabinet doors, pvc paneling and modular furniture.
