The ultraviolet spectrum (UV) can be described as a form of energy that is visible in the electromagnetic (EM) spectrum, which is in between visible light and the x-rays. It has less distance than visible light, but it has higher intensity (or frequencies).
Wavelength = distance between two the peaks, which is in nanometers.
Frequency is the number of waves in a given time, determined per second, or Hz.
Short wavelengths are high-frequency wavelengths that are shorter in duration.
Long Wavelength = less frequency wavelengths require more time to be completed
The EM spectrum is comprised of seven regions that are based on frequency and wavelength.
Radio Waves – Long waves that are used in radio communications, such as voice, radio data, and various other forms of media.
Microwaves – Heating source for microwave ovens, radar , and high-bandwidth communications.
Infrared light is not visible to the human eye , it can be perceived as heat. Think of a toaster.
Visible Light is visible by the human eye.
Ultraviolet (UV) cannot be detected through the naked eye, and is broken down into B, A, C & V
The X-rays produced through the acceleration of electrons. Dangerous.
Gamma Rays are x-rays produced by atomic nuclei can kill cancerous cells. Extremely dangerous.
UV generated by the Sun against Man-made
The sun’s rays contain only 10% UV, and only 1/3 of that UV enters the atmosphere of Earth. Of that third the majority is UVA which is the one with the lowest energy, and is all the time all around us. It causes skin to tan as well as cause cellulite to increase and can damage DNA.
UVB is responsible for the remaining 5 percent of the total and UVB is the UV that causes DNA damage directly within skin cells. It can cause cataracts, sunburn and the majority of skin cancers.
UVC is the one with the most energy however UVC from the sun can not penetrate Earth’s surface due to it being block by the Ozone. UVC is destructive and damages genetic material. UVC is used to cleanse water and air as well as to sterilize and disinfect. UVC is generated or created by running an electric current through mercury that has been vaporized. The artificial (man-made) lighting sources for UV include tanning lamps mercury vapor lamps, as well as germicidal lamps.
The health benefits of UV
The sun’s warmth is a great way to bring out the best of many of us. It helps us feel more energetic and boosts our mood. The exposure to UVB sunlight boosts vitamin D production. This provides numerous health advantages, including producing serotonin. Vitamin D improves sleep, stronger bonesand better immune system and lowers blood pressure. Another benefit of UV is its treatment of certain skin diseases. A light treatment that makes use of UVA exposure to light in conjunction with cream or drug and is thought to combat eczema, vitiligo, lymphoma, and psoriasis.
The Common Everyday Utilization of UV
UV is employed in the process of drying out and disinfecting many items you’ve probably come across and buy. Dentists often make use of UV to cure resins , or to whiten teeth. Also, nail salons employ tiny UV heaters to speedily dry polish. 3D printers and UV printers are used to rapidly dry ink on models and paper.
Although these are all common applications Did do you realize that ultraviolet light is also employed to pasteurize juices and eliminate food-borne microorganisms? Apple cider, as well as other juices, are typically treated using UV light to kill the pathogens that cause microbial infections. UV-C is utilized for greenhouse irrigation in order to clean the water that is contaminated to cleanse vegetables, lettuce and other fruits. Water that is contaminated can trigger an outbreak of E. E. coli that can cause widespread illness.
Germicidal Lamps
The COVID-19 pandemic resulted in several companies and individuals purchase germicidal lamps to clean their offices and homes. In the event of an insufficient supply in N95 respiratory masks, UV suggested as a method of cleaning respirators in hospitals. It was the NIH also published a research study declaring that N95 respirators that were cleaned by ultraviolet and VHP (vaporized Hydrogen Peroxide) could be used for up to 3 times over as long as the wearer is able to verify that the mask is properly fitted.
UV Curing Lamps for manufacturing
Numerous manufacturing industries employ UV to make the products you see every day. UV’s quick-drying, energy efficient and environmentally friendly technology produces zero Volatile Organic Compounds (VOCs) and is utilized for the manufacturing of numerous items, such as:
Food cans and soda
aerosol hairspray
Caps for bottles and lids for jars
toothpaste tubes
plastic and styrofoam cups
Garden and pet supplies bags for pet food and garden supplies
hardwood flooring and high-end vinyl tiles (LVT) flooring
packaging of all kinds
automobile parts, like headlights and windshields for cars
Cell phone components of cell phones
Space is always at a premium when it comes to manufacturing facilities and, depending on the specific application that includes UV curing lamps to a line of production can help a business save space. Traditional thermal drying ovens designed for high-volume production lines range from between 50 and 200 feet in length depending on the type of application and the speed of processing. However, the UV curing chamber that is used that is designed for the same applications will take only 3-10 feet. The introduction of UV curing in the production line will bring faster production speeds as well as shorter cycle times and substantial production and cost savings.
