Modern technology has made great strides in the development of tools to aid in our everyday lives. Businesses, social interactions and home lives have all been changed in different ways by technology. Today, we will be taking a look at a light bulb with a different use, UV curing. Included here are a few uses for these UV light bulbs.
Curing Processes
When UV radiation was first discovered in the early 19th century, it was referred to as “chemical rays.” This is because the UV lighting had the ability to chemically change substances when the light was shone on them. This process is now referred to as “curing” and is utilized in many industries.
UV light bulbs are used as a cost-effective method of quickly drying a variety of inks, adhesives, lacquers, varnishes and decorative glazes. Because these bulbs are low-maintenance, highly efficient, and do not produce chemical byproducts they are viewed as an incredibly useful tool in manufacturing. UV bulbs are now used by designers, engineers, and manufacturers in a variety of manners.
Sterilization
In recent years, the chemical compound changing effects of UV have been looked at in relation to microbiology. Many scientists are now heralding UV light for its ability to destroy unwanted microorganisms. For instance, some bacteria present in your freshly washed clothes can be deactivated by a session of hanging outside in the sun.
Additionally, UV can be used in even more admirable practices, such as sterilization of medical equipment. UVC light can be used to destroy the DNA strands of many bacterias and viruses, making them useless by way of inability to reproduce. This is helpful in sewage treatment as well as in hospital settings.
Have you ever wondered if that fresh stream flowing off a mountainside was safe to drink? Don’t risk contracting Giardia or worse, utilize UV light! The SteriPEN is a new method of cleaning water instantly when you are out backpacking or camping. In only 48 seconds, the exposure from a SteriPEN’s UV light can eliminate Giardia, E-coli, Legionella, Hepatitis, Cholera, Salmonella and even Shigella.
Skin Tanning
One of the more controversial uses for UV bulbs is in the industry of skin tanning. Because UV bulbs utilize electromagnetic radiation, there is risk of cancer development in the skin. The same chemical changes that make UV a popular curing technique also make it dangerous for human skin.
Regardless of risks, millions of people worldwide still take a trip to the tanners on a regular basis. While the UVB found in sunlight does offer valuable vitamin D, it can cause irreversible skin damage. Before heading to the tanning salon, take a peek at some fake-tanners 20 years down the road and consider popping a supplement instead.
