Advantages of Using a Handheld UV Curing Light The handheld uv curing light is a powerful curing device that can be used in various applications to cure adhesives, glues, coatings and more. The light emits UVA, UVB and visible light to cure the substrate being used. It can be attached to a power supply to deliver varying degrees of intensity depending on the application and curing needs. The light is available in different configurations that can help a user find the right option for their business. There are many advantages to using a handheld uv curing light, including their compact size and versatility. They are easy to use and can be placed in hard to reach areas. Some even have a retractable wand that makes them easier to use in tight spaces. Additionally, handheld uv curing lights can be easily carried and stored in a case. Some uv curing devices come with additional features that allow the user to customize the curing process, such as the ability to set an alarm or timer. These features can be helpful for users who are working with difficult to cure materials or need to speed up the curing process. UV curing technology has been around for decades and is a widely used method of finishing products, such as inks, paints, and adhesives. The underlying principle is that ultraviolet radiation activates a chemical reaction in the material that causes it to bond to itself and other surfaces. This method is extremely effective and allows companies to create high-quality finished products in a fraction of the time that would be required to make them by hand. One of the main disadvantages of traditional UV curing lights is that they can be very expensive, especially when compared to LED curing systems. They are also dangerous because they use mercury-based bulbs that are toxic if they break. LED systems use an entirely different technology that is safe for the environment, safer for employees, and much more affordable. If you are looking for a high-performance handheld uv curing light, look no further than the Spectratek Instacure 500. This powerful unit can cure UV undercoats, clearcoats, primers, putties, and fillers in just seconds. It can be programmed for automatic or manual curing and is easy to store in a custom case. The 365nm handheld uv curing light is designed for small and medium cure areas. Its ergonomic shape provides a comfortable grip, and the unit comes with a solvent resistant glass lens. The unit is also equipped with a smart battery indicator to let you know when it’s time to exchange the battery. There are many factors that determine whether a UV light can effectively cure resin, such as the type of product being used and its intensity. For example, a UV flashlight may not be strong enough to cure epoxy resin. In addition, the curing process must be followed closely to avoid any potential issues with the finish. Lastly, UV light can cause an intrapulpal temperature rise, so it’s important to wear proper eye protection to prevent blue-light-induced retinal injury. Tags:lamp uv

Wavelength classification and application fields of ultraviolet light According to the different biological effects, ultraviolet rays are divided into four wavelength bands according to wavelength: long-wave UVA, medium-wave UVB, short-wave UVC, and vacuum UVD. The longer the wavelength, the greater the penetration.   UVA Long wave UVA, with a wavelength ranging from 320 to 400 nanometers, is also known as long wave black spot effect ultraviolet radiation. Has strong penetrating power, able to penetrate glass, even up to 9 feet of water; And it exists throughout the year, regardless of whether it is cloudy or sunny, day or night.   Harm to human body: More than 95% of the ultraviolet rays that daily skin comes into contact with are UVA, so it causes the greatest damage to the skin. UVA can attack the dermis through the epidermis, causing severe damage to collagen and elastin in the skin; Moreover, dermal cells have poor self-protection ability, and a small amount of UVA can cause great harm. Over time, the skin develops problems such as looseness, wrinkles, and the appearance of microvessels.   At the same time, it can also activate tyrosinase, leading to immediate melanin deposition and the formation of new melanin, making the skin black and lacking luster. UVA can cause long-term, chronic, and long-lasting damage, leading to premature aging of the skin, hence it is also known as aging radiation.   Application field: UVA ultraviolet radiation with a wavelength of 360nm conforms to the phototactic response curve of insects and can be used to make insect traps. UVA ultraviolet rays with wavelengths of 300-420nm can pass through specially colored glass tubes that completely cut off visible light, emitting only near-ultraviolet light centered at 365nm. They can be used for ore identification, stage decoration, currency verification, and other places.  

UV LED curing UV LED curing is a type of UV curing. It uses UV LED light source to curing UV inks, UV glue, UV coating, etc. As we all know, more than 30 years ago, UV (UV light) was successfully promoted to commercial applications. The adhesive producers have developed a series of UV products for adhesion, sealing, printing, and printing in response to UV optical solidification curing, and are widely used in many fields such as communications, electronics, optics, and printing. These products will be solidified or hardened (aggregated) under UV light (a certain wavelength and a certain light intensity), and are more efficient, energy -saving and environmentally friendly with the traditional product -UV optical curing.     Equipment features The emergence of UV LEDs has brought revolutionary changes to the UV curing industry. It has the characteristics of constant light intensity, excellent temperature control, portability and environmental protection, relatively low procurement costs, and almost zero maintenance costs, which have played a driving role in improving the quality, energy conservation, and consumption reduction of UV curing processes.         Use  life Compared with the traditional UV curing equipment, the use of mercury lamps is only 800-3000 hours, and the service life of UV LED ultraviolet curing systems is 20,000-30000 hours. The LED method can be lit instantly when the ultraviolet is needed, and when duiy = 1/5 (preparation time = 5 irradiation time = 1), the service life of the LED method is equivalent to 30-40 times the mercury lamp mode. Reduce the time to replace the bulb: improve production efficiency, but also very energy -saving. When the traditional mercury lamp method curing equipment, when the lamp lamp is started slowly, and the opening and closing affects the life of the light bulb, it must be lit all the time, which not only causes unnecessary power consumption, but also shortens the working life of mercury lamps.     Environmental protection and pollution The traditional mercury lamp method curing machine uses mercury light to light up. There is mercury in the light bulb. The waste processing and transportation are very troublesome. Improper treatment will cause serious pollution to the environment. The LED -type curing machine uses semiconductors to light, and there is no factors that cause pollution to the environment. Therefore, the LED -type curing machine is more environmentally friendly.     Low energy consumption The UV LED method is more than 10 times more effective than the mercury lamp method. At the same time, no matter whether the mercury lamp method is effective or not, mercury lamps need to be continuously lit, and the electricity has been consumed. The UV LED method only consumes electricity during irradiation, and the power consumption is almost zero during standby.     Simple installation, saving space The volume of the LED curing machine is only 1/5 of the traditional curing machine, making the installation of the equipment easier, reducing the area occupation area of the production site.

Reasons why LED lamps are more popular than traditional UV lamps: 1. Since the LED does not emit light with a wavelength of 280nm and below, it will not produce ozone, and no additional exhaust equipment is required. 2. LED lamps generate less heat than traditional UV lamps. LED lamps generate heat at 60°C, while mercury lamps generate heat in excess of 350°C. In order to remove heat, a large amount of cooling equipment is required. 3. The LED light can be turned on and off instantaneously. Ordinary UV curing lamps need time to warm up. If the bulb is turned off, a certain amount of cooling time will be required after it is turned off. In order to solve this problem, mercury lamp manufacturers have also specially developed shutters to reduce the start and stop time. 4. Due to the need for exhaust, cooling and heat dissipation, traditional UV lamps are bulky. The LED lights are very small. 5. The service life of LED lamps is longer than that of mercury lamps. The working life of LED lamps is> 20,000 hours, while the rated value of mercury lamps is usually between 1000 and 2000 hours. 6. Traditional UV lamps contain a small amount of mercury and must be properly disposed of. LED lamps do not contain mercury. 7. LED lamps are rarely maintained. Traditional UV lamps need to be replaced every 700-1000 hours. The reflector also needs to be cleaned when the lamp is replaced.   After talking about the advantages of LED, let’s talk about the disadvantages of LED lamp technology: 1. Due to the limited number of available photoinitiators, it is challenging to cure paints and coatings with LEDs. The photoinitiators used to cure these products have a tendency to turn yellow during curing. 2. The choice of raw materials (especially photoinitiators) that can be used for LEDs is limited, so the price of LED inks is higher than traditional UV curing inks (about 10% higher). 3. Since the LED light does not contain short wavelength (below 320nm), it can only cure the part related to it. 4. At present, the cost of LED lamps is about twice that of traditional UV lamps. Over time, costs will continue to fall. 5. The power output of the LED lamp is continuously improving, but it is still inferior to the traditional UV lamp. 6. The oxygen suppression effect that affects the photocuring must be reduced.
