Types and Phenomena of Poor Ultraviolet Curing

There are often various solidification phenomena in UV curing technology. The most prone to bad phenomenon is the following. However, sometimes the reason for the poor curing is comprehensive. In other words, sometimes 2 or more solidified phenomenon occurs at the same time in the same product. The specific solution is to contact the technical personnel of the manufacturers of UV resins, UV mercury lamps, product materials, and UV curing machines first, or completely detect the real cause of the phenomenon of solidification. Effective solution. The concept of poor solidification, so -called solidification, means: first, there is no complete solidification state, that is, the state of not hardening; second, the state of excessive solidification, that is, overcured. If the phenomenon of hardening occurs, it will be burned by the cure, or the heat change phenomenon will occur due to the high calorie of the curing bin. If the phenomenon of unseenized phenomenon is because the resin is not completely solidified, the product is sticky, the adhesive force will be significantly reduced, or the resin solution that is not solidified on the surface of the product. 1. Product thermal deformation heat does not have much effect on metal or wood, but the thin plastic series of film or film products is very sensitive to heat. The calories are extremely sensitive, so it can be said that the top priority in the work of solving product thermal deformation in this field. 1) Wave: Thermal deformation is primary stage. 2) Curl: Start partial deformation. 3) Shrinkage: serious local deformation. 4) Carbonization initial stage: all turn yellow, black, and severe thermal becomes serious. 2. Although the adhesive effect seems to have completed the curing process, the adhesion effect between the materials and the coating is not good. It may be scraped with a nail or coin gently, the curing layer will be scraped off, and the cross -cutting test cannot be tested. Mobile parts, LCD display parts or films, COG/BGA and other chip components must be very firm. 3. Swaging, Bulging) The mother material that needs to be painted is like plastic or rubber, which is very sensitive to thermal material. Part of the mother material or resin will swell out due to heating when curing. , It will cause the phenomenon of burning of the mother material or resin. The expansion of the internal and external bending is severe, and the phenomenon of bubbles appears inside, so that the appearance after solidification will not look good. This kind of bad appears in the optical film and mobile phone display flat solidification. 4. Bubbling (Bubbling, Air Bubble) film, high -quality film and other precision films, although the solidification and bonding can be fully completed, if you observe it with a microscope, you will find that there are fine and micro -cracks existing. The reason for it has not yet been concluded, which is also the phenomenon of bad product that is difficult to solve. We believe that this is the result of the crystal of the resin in the horizontal distribution after the resin is solidified. 5. Surface crack film, high -quality film and other precision film. Although the solidification and adhesion can be fully completed, if you observe it with a microscope, you will find that there are fine and micro -cracks. The reason for it has not yet been concluded, which is also the phenomenon of bad product that is difficult to solve. We believe that this is the result of the crystal of the resin in the horizontal distribution after the resin is solidified. 6. The phenomenon of yellowing is a phenomenon that occurs more when solidifying on transparent resin. You can reduce the phenomenon of yellow change from adding yellow changes in the composition of resin to reduce the phenomenon of yellow change. 7. Film non -dry glue ink printing commonly used thin -film non -drying materials are: polyethylene, polypropylene, polyester, polyvinyl chloride, polystyrene, polyolefin, etc. But the difference is that the film is not absorbed. Therefore, the printing of the film does not dry glue mainly uses UV convex marks and UV soft printing. However, in the process of printing and processing, the problem that label printing companies often encounter are the insufficient paste of UV ink on the surface of the film. The solidification has a great impact on the stretch strength. With the increase of the curing of the adhesive, the cross -linked density increases, the average molecular mass of the cross -linking point becomes smaller. If the epoxy and polyurethane acrylics are coordinated, the adhesion will be greatly enhanced.

Sunlight remains the most common source for achieving a tan, but its ultraviolet (UV) rays come with inherent risks. So is there any risk-free solution for this? Yes, and the answer is UV LED Lights. Let’s not waste a second and dive into the science behind UV light and tanning, explore traditional tanning methods, and introduce Tianhui UV LED, a leading supplier of UV LED solutions, as a potential alternative.
In the food and beverage industry, ultraviolet (UV) disinfection technology is a rapidly expanding sector. UV radiation is used to disinfect water, air, and surfaces by killing bacteria, viruses, and other pathogens to make the food healthy. This technology has grown in popularity due to its efficiency, usability, and minimal cost.
The rapid expansion of the electronics industry has necessitated the development of new and innovative technologies to propel the industry forward. The application of UV LED solutions is one of the emerging technologies in the electronics industry. Due to their unique characteristics, such as long lifespan, energy efficiency, and compact size, these solutions have been extensively adopted in the industry as a suitable alternative to conventional lighting sources.
UV LED curing is a technique that employs ultraviolet light to cure or harden substances. This procedure involves exposing the material to UV LED diodes emitting UV light. When UV light strikes a substance, it initiates a chemical reaction that causes the substance to harden or resolve. UV LED diodes emanate UV-A, UV-B, and UV-C light, which correspond to the wavelengths required to initiate the curing process.
Throughout the years, ultraviolet (UV) light as a disinfectant has gained popularity. UV LED has been used as a UV LED solution that is capable of killing a variety of microorganisms, including bacteria, viruses, and mold. It is also known as UV LED Disinfection process.
As summer approaches, so does the pesky problem of mosquitoes. These tiny insects can ruin a peaceful outdoor evening, leaving us with itchy bites and disease risk. Fortunately, there's a solution in the form of UV LED mosquito traps. These devices use the power of ultraviolet light to attract mosquitoes and other flying insects better.
Are you aware of the latest findings on the transmission rate of the new coronavirus? A recent study has uncovered a shocking discovery- the air transmission rate of the virus may be a staggering 1,000 times that of the contact surface! This means the virus may spread faster and farther than we previously thought. Keep reading to learn more about this groundbreaking research and what it means for our fight against the pandemic.
UV LED printing system is a cutting-edge technology that has revolutionized the printing industry by offering faster printing speeds, improved print quality, and increased energy efficiency. However, like any technology, it has its own pros and cons.
Are you looking for a robust and flexible solution to disinfect your space? Look no further than mobile UV units. These innovative robots move from room to room, eliminating harmful germs and bacteria on surfaces. Mobile UV led diodes are becoming popular as more industries outside of healthcare catch on to the benefits of UV disinfection.
UV LED, also known as Ultraviolet Light Emitting Diodes, is a solid-state device that produces light as soon as you pass electrical currents in a circuit. These currents pass from the positive side to the negative side of a current.
