There are several types of UV inks: cationic optical curing UV ink, water -based UV ink, hybrid ink, etc. The UV ink of cationic optical curing system is currently the research field that people are concerned about. The light curing system UV ink does not produce unpleasant smell after curing, and once the cation is generated after being raised by UV light, the solidification reaction can continue to be continued after stopping the light. This is difficult to achieve the free radical light curing system. 2. Not suppressed by oxygen, which is conducive to the height of the ink surface, making the coating tough and shiny. And the free radical light curing system ink is severely suppressed by oxygen ink. 3. After the cationic optical curing system UV ink is cured, the volume shrinkage (generally 3% 5%), so it is conducive to improving the adhesion of the substrate. The volume shrinkage of the volume of the free radical light curing system is generally contracted by 10%, which has a greater impact on the adhesion of the substrate. Therefore, the UV ink or free radical/cationic optical optical curing system UV ink with cationic optical curing system UV ink can improve the speed of optical curing, especially for the solidification of the colored UV ink and the thicker network printing UV ink, more For benefits. From the market growth rate of cationic curing materials higher than the total growth rate of the UV curing market, it can be seen that the UV ink with a cationic optical optical curing system or a free radical/cationic composite optical system will be the new development direction of the UV ink. For the characteristics of cationic optical curing system UV ink, how should we choose a solid light source? Following the study shows that the exciting molecular lamp with a wavelength of 308nm is particularly effective for the curing of the uV ink of the cationic optical system UV ink. As far as the UVLED light source is concerned, it can be mixed with 310nm, 365nm, 385nm UVLED lamp beads in light sources.

Installed COB light source development.”Liu Lin, deputy general manager of the same party. It is understood that the COB light source is a naked chip technology used for LED lighting. Putting multiple LED chips in a small unit forms a COB LED lighting module. For LED packaging, this is also a relatively new technology. It installs the LED chip directly on the substrate, forming the LED lighting module Shantou inverted COB light source. Set up. (B) After welding, the temperature of the product drops to room temperature, carefully pay attention to handling the product. COB light source mainstream trend is still“Heroic”随着照明技术的不断进步应用市场的逐渐成熟COB光源成了封装发展的主导方向之一其散热性能好造价成本低体积小可高密度封装至硅片牢固地固定在Until the base, then use the method of wire welding to directly establish electrical connection between the silicon wafer and the base. COB's advantage: In terms of cost, compared with the separated light source devices, the COB light source module can save the cost of component packaging, the production cost of the light engine module, and the secondary lighting cost in the lighting application. In the lighting lamp system of the same function, Shantou inverted the COB light source to cool the COB light source to dissipate fast heat, plus the golden technology, which will almost cause serious light attenuation. So rarely die, which greatly extend the COB light source life. 6. Good Blu -ray suppression: Breaking through the LED world's blue light limitations, good blue light inhibitory can help protect the eyes and ensure the light effect. As the most important material foundation in the packaging structure, the heat dissipation substrate is to bring a large amount of thermal conductivity generated by the chip to the bridge of the radiator. At present, it focuses on different segments. COB is mainly used for key lighting and narrow light beam corners. In the expected future, they will still play a role in their respective market segments. The inverted is replacing the general trend, but is it completely replaced? Although in the next 1-2 years, the inverted COB will pour the COB light source from high-power outdoor and industrial Shantou COB light sources. The COB light source high quality, application advantages, stable electrical parameters, high cost performance and other comprehensive performance advantages jumped and jumped. The head of the industry is in the COB packaging industry in the leading enterprise. Product performance: COB light sources developed for the LED application commercial lighting market, have good anti -sulfurization performance, color consistency, and excellent anti -mechanical damage capabilities. There is no dead lamp after the hot and cold shock (-40 100 ), the golden line,

There are different test standards in each industry. Among the electrical and photoelectric products, the ETL inspection sign indicates that it is tested that it meets the relevant industry standards that meet the relevant industry standards. The ETL inspection logo is widely used in photoelectric products. With the development of the economy, there are more and more related applications involving the ETL authentication AC light source module. But when we apply ETL authentication AC light source module, it will cause problems. So what should we pay attention to? At present, as the LED display is widely used, consumers usually require manufacturers to help installation when buying LED display. Although for sophisticated technicians, the LED display installation can be described as light cars, but for some technicians who have just touched the LED display, it is often easy to ignore some places when installing the LED display, which leads to unnecessary unnecessary unnecessary. There was a problem. 1. The input method used by ETL authentication AC light source modules is low pressure, so you must not enter 220V directly, otherwise the entire module will be damaged, which will cause unnecessary losses. 2. When installing the ETL authentication AC light source module, it is required to use double -sided or woodworking glue to make the module card slot and the plastic base plate firmly paste. When using double -sided glue, you must add glass glue, otherwise it will cause the module to fall off under long -term exposure of the outdoor sunlight. This is quite important. 3. When installing an ETL authentication AC light source module in the sucking word or the box, try to use three points and quarter lines as much as possible to form a loop or multiple circuits in the entire word or the box when connecting. Red and black power cords connect the modules at the end of each stroke according to the positive and negative electrode. When the power cord is connected to the box, it must be connected to the corresponding four or three sets of modules through a quarterly line or a three -point line first. After the power cord enters the box, a large knot should be played to prevent ETL authentication AC light source module. 4. Adjust the output voltage of the ETL authentication AC light source module according to the actual situation. When the module is used in the use process, it cannot adjust the voltage at will, otherwise it will cause an impact. 5. Install the ETL authentication AC light source module without waterproof treatment. Pay attention to whether there are water entering. Moreover. 6. When installing the ETL authentication AC light source module, it should not be too hard to avoid destruction of the device and affect the overall effect. 7. ETL authentication AC light source module has a positive and negative pole. Pay attention to whether the power port wiring is positive and negative during installation. If the positive and negative is the opposite, then the module will not glow. But dont worry, it will not damage the module when it is connected. Just take it back to the normal direction. 8. ETL authentication AC light source module spacing can be adjusted according to the requirements of the brightness. Each square meter cloth is generally controlled between 50 and 100 groups. 9. The number of connected groups in the power port is recommended not to exceed 50 groups, otherwise the tail module will cause the ETL authentication AC light source module due to voltage attenuation. Although this phenomenon can be weakened through the method of circuit, it is not recommended to connect too many modules. 10. Generally, when connecting the ETL authentication AC light source module, the wires are firmly inserted, so as not to cause future falling off. In order to prevent the occurrence of falling off in the future, it is usually refueling on the online design. If the connection is inconvenient, you can exit and re -insert.

UV curing ink (ultraviolet curing ink) is called UVLED ink. Ultraviolet light is printed on the ink layer, which can be immediately widely used in a complete cured ink. Packaging and Printing.
