The Pigment Is Affecting the Water -based UVLED Ink Curing

As a non -optical component in the water -based UVLED curing ink, the competition of pigments and causes to absorb UVLED light, which greatly affects the solidification characteristics of the system in the UVLED curing system. Since the pigment can absorb a part of the radiation energy, this will affect the absorption of light caused by the light cause, and then affect the concentration of the free radicals that can be generated. As a result, it will reduce the curing speed. Each color has different absorption rates (light transmission) of different wavelengths. The smaller the absorption rate of the pigment, the greater the light transmission rate, and the faster the coating. Carshrilia's ultraviolet absorption capacity is high, the slowest solidification, strong white pigment reflector, which also hinders solidification. Generally speaking, the order of absorption of ultraviolet light is: black> purple> blue> blue> green> yellow> red. Different colors are different, and the concentration of pigments of the same color is different. The effect on the fascination of ink membrane is different. As the amount of pigment increases, the curing rate of the ink film has decreased to varying degrees. Among them, the amount of yellow paint has the greatest effect on the curing rate of the ink film, followed by red pigments and green pigments. Because the black absorption rate on ultraviolet light is the highest, the light transmission rate of black ink is the lowest, so the change of the amount of dosage has no significant effect on the curing rate of the ink film. When the amount of pigments is too large, although the curing rate of the surface layer of the ink membrane is fast, the surface of the surface of the surface absorbs a large amount of ultraviolet light, reduces the light transmission of ultraviolet light, affects the curing of deep ink membranes. Do not solidify, it is easy to produce "wrinkle skin" phenomenon. In summary, the color of the pigments is different from the concentration of the pigment that affects the water -based UVLED ink light. After understanding the reason, we should be targeted when selecting the UVLED optical curing system. Different from irradiation time, etc. The effect of the pigment curing is also different.

Deep Ultraviolet Disinfection Sterilization How To Use The Car?
Deep Ultraviolet Disinfection Sterilization How To Use The Car?
UV cleaning of surfaces and air has become more prevalent from outside medical settings with the advent of COVID-19. Several airlines are now employing Air Disinfectionto eliminate any bacteria that might be present in the HVAC system and on flight electronics panels. Additionally, a broad variety of low-output UVC disinfection tools have been offered for use in restrooms, interiors of personal and commercial vehicles, and other tiny places. However, there are several difficulties when employing UV-C germicidal irradiation to clean the inside of vehicles. The cab of a semi-truck or the interior of an automobile may require more than just cheap UVC equipment. Can UVC Clean The Inside Of Cars And Trucks? The first concern is if UVC Air Disinfectioncan clean the interior of automobiles and trucks in any way. Thankfully, the solution to this is simple. No bacterium has yet been identified that is resistant to ultraviolet irradiation. Therefore UVC light wouldn't encounter any further obstacles when it came to neutralizing hazardous pathogens in a vehicle. To clean the air and surfaces in cars, UVC Air Disinfectiondevices can be utilized. But there may be difficulties in these regions. Problems with UVC Use in Fabrics for Vehicle Interiors The CDC suggests using a UV radiation of 1,000 MJ/cm2 to sterilize N95 masks, which is an extremely high UV exposure. It is far greater than the UV dose necessary to render SARS-cov-2, the virus causes COVID-19, inactive in 99.999%, and the UV dose necessary to render MRSA, C. Diff, and other infections inactive. Due to the nature of N95 masks, which are constructed of fabric with patterns and shadows that UVCAir Disinfectionmay not infiltrate well or will create locations for germs to hide in shadows, the CDC advises using this much UVC. This problem will affect almost everything fabric interiors of vehicles and trucks. Leather seats and cushions won't experience the issue to the same extent as those made of fabric, but textiles will need more UV because of the light's poor light penetration. Shaded Regions Large sections of the vehicle's interior may not be covered if only one UVCAir Disinfectiondevice is used. Where the sunlight does not shine, shadows may be cast by seats, the steering column, the center console, and other items.UV sanitation will be minimal in areas without UVC Air Disinfectionlight. Central heating and cooling for vehicles UVC Air conditioning units make a ton of sense and could be the most efficient use of UVC for residential and commercial buildings. They work in tandem with filters to eliminate large particles and neutralize tiny microorganisms as the air circulates through the ducts. There isn't much space to install a UVC HVAC system in a commercial or personal vehicle, and we haven't seen any readily available kits from vendors. This means UVC Air Disinfectionof an automobile's interior should only be done between travels. As a result, UVC is a very limited option for cars in use, and long-term far-UV exposure has not yet been shown to be safe for all varieties of human skin and eyes. Ideal Techniques Clean Surfaces First UVC is most efficient when combined with other hygienic procedures. Large particles and bacteria can be removed from surfaces by wiping them down with a cleaning solution. Smaller particles may also be aerosolized, which will facilitate UVC action. Evenly Place Several UVC Units No matter where UVC devices are installed in the car, there may be various areas of shade. Therefore it may be more sensible to employ many UVC devices than to boost the power of a single lamp. Additionally, it can store UVC equipment near cushions and seats that require high UV dosages.

Additionally, it can store UVC equipment near cushions and seats that require high UV dosages. Portables for Problem Areas Finally, handheld UVC devices can be utilized to access extremely challenging locations with permanent UVC equipment. This might be in places where UV-led modules wouldn't typically penetrate with the devices, including behind seats or in the glove box. Handheld UV devices don't make much sense as a primary option due to the enormous surface area inside a car or truck and the amount of time needed for UV-C to be effective, but they can be a useful addition.

Directly Inserted LED Lamp Beads Manufacturers to Talk About the Difference Between LED Lamp Beads
Directly Inserted LED Lamp Beads Manufacturers to Talk About the Difference Between LED Lamp Beads
Directly inserted LED lamp bead manufacturers to talk about the difference between LED lamp bead bracket information: At present, there are aluminum brackets, brass brackets, copper brackets, etc. on the market. Even if it is a copper bracket, the price of silver plating is divided into up and down. The market is generally called a good stand. The difference between chip size: The size of the chip that is usually reported is MIL. It is difficult to distinguish the size of the chip. It is 230 square MIL, the size of the chip area is a good way to distinguish the size of the chip. The difference between welding line information: The chip and bracket are used to complete the electrode connection with the gold wire welding method. At present, there are two types of alloy lines and pure gold lines on the market. Pure gold lines are divided into 0.7, 0.9, 1.0, 1.2, etc. The thicker the golden line, the lower the thermal group, the longer the life span, everything should be asked about the materials and diameter of the golden line. The difference between fluorescence powder: white light beads are made of blue -light chip and yellow fluorescent powder. The fluorescent powder is mainly divided into aluminum acid and silicate. The performance of aluminate is better than silicate. , YAG performance is stable, low in light, and the chemical stability of the silicate itself is poor, but the brightness is higher than YAG. If you want to make a product with stable performance, don't be fooled by the so -called high brightness. This is a problem. The difference between glue: The fluorescent powder should be stirred with glue and on the chip. The quality of the glue affects light decay and color drift. The poor glue time will be yellow, and the light decay will increase. Good glue is jelly. glue.
