UV Curing Lamp
UV Curing is a photochemical process by which specially formulated liquid monomers are polymerized, or Cure by exposure to ultraviolet radiation.
The UV-Curable monomers contain sensitizes that absorb UV energy which then produce very rapid polymerization.
The relative speed of curing depending on several factors, including the chemical formulation and thickness of the monomer, and the intensity and spectral distribution of the ultraviolet source.
What is Ultraviolet Light Ultraviolet radiation cover a band of wave lengths just beyond the eye's capabilities. This Board band of the UV Spectrum is divided into three ranges:
Long Wave UV-A 320-420nm
Mid Range UV-B 280-320nm
Short Wave UV-C 180-280nm
Future distinctions in wave lengths are often made to define their application :
Ozone Production 184.9nm
Germicidal 253.7nm
Erythemal 300.0nm
Black Light 365.0nm
UV Curing 180-420nm
Advantages of UV Curing
High Productivity fast curing can be achieved at ambient temperatures there by shortening production times and minimizing stacking.
Energy Serving : UV Curing consumes only 20% of the energy needed to cure solvent-based coatings.
No Air Pollution : UV Curable materials are “Solvent Free” and therefore do not release residues or gases into the environment.
Low Heat Output : Because ultraviolet, instead of infrared radiation is used, fragile materials such as paper, plastic and thin films can be processed safely.
Space Saving : UV Systems are usually smaller in size than their conventional counterparts.
UV Curing Applications
New uses of UV Curing are being developed everyday. Among them most wide used are :
- Plating Ink
- Screen Printing On Glass
- Printed Circuit Boards
- Graphic Art
- Metallic Decorations
- Plaint Drying of Plywood
- Setting Adhesives
- Surface hardening
- Photolysis of Toxic Waste
UV Curing Units
There are three types of cooling systems.
1. Air Cooling
2.Water Cooling
3.Combined Air and Water Cooling
Cooling systems for the material to be coated can be added, for example: water plates for the label printing machines.
Most important for the cooling is :
Optical lamp cooling about 600C-900C lamp tube temperatures. If the temperature is too high, the result is diversified , especially in combination with impurities.
At temperatures above 1000C the quartz soften and the lamp blows up or will bend under it’s own weight. It is also important to have the correct temperature at the sealing. It should not exceed 350C. If the temperature is too high, the sealing foil might oxidize and the lamp will lose its vacuum.
Ozone must be removed so that the KAM-value of 0.1 PPM will not exceed. Ozone is unstable and will disintegrate into oxygen after a few minutes.
The picture below shows the most common type of air-cooling. The hot air above the lamp is removed and fresh air can get the housing. Air flow should be between 30m/h – 50m/h depending on lamp Kw.
UV Curing
The UV-emitters are designed for high output in the UVC spectral range ,But can be adapted to the UVA or visible spectrum. The UV-emitters in the table represent only a sample of a much larger program. We can offer various lamp caps and can manufacture lamps to meet specific demands. Ask our experts about the correct emitter for your application. We are able to offer the widest range of original and replacement UV curing lamps all of system.And to meet your exact requirements in power ranges from 80 watts per cm up to 550 watt per cm .Together with a selection of ceramic and metal end caps,lead terminations can be altered to suit your equipment.
Mercury arc lamps are effective in the whole spectral UV range from 200 nm to 400 nm.
Gallium lodide has intensive spectral lines at 403 nm and 417 nm. This is particularly.
Iron lodide enhances the spectral output in the 380 nm region. This is used with good effecton photopolymer and daylight film exposure systems.
