Compared with ordinary inks, UVLED inks have good printing adaptability, color stability, stacking effect and lightness. its solidification speed is fast. Under the light of UVLED UVLED, it can be solidified for a few seconds, especially in packaging and printing. It is often necessary to print a large area of large -scale fields. At this time, the problem of drying becomes very important. Ink is not easy to dry, it often affects the efficiency of printing production. Instead, the UVLED optical ink is used in ultraviolet rays. UV UVLED ink can also prevent the ink cutting skin, solving the worries when the plastic printer is stopped. The conjunctiva is good and has good adhesion for various types of printed materials. Because the ultraviolet UVLED ink does not contain solvents, the thickness of the ink layer after curing is basically the same as the thickness of the printing ink layer. Compared with, 30 % -50 % of the printing area is large. There is no penetration when curing, and can be printed on non -absorbing materials, such as the printing of the card card, etc. This is an area where ordinary plastic printing ink cannot be involved in. Because the UVLED ink does not need to be sprayed when printing, the printing environment has been improved well, and the troubles that are caused by the processing of printed due to the spray spraying, such as the impact on the effect of light and coating. Can be connected. UV UVLED ink color is colorful, and its scratch resistance, abrasion resistance, acid and alkali resistance are better than ordinary ink. Therefore, although its price is much more expensive than ordinary ink, it is still widely used in widely used. For more consultation, please log in to the official website of tianhui

In recent years, more and more scientific research units are consulting Tianhui's UVLED light sources. Among them, there are many Chinese Academy of Sciences and some universities. Previously, a teacher of a well -known college purchased UVLED of Tianhui. When asked what they used to do with UVLED, they told me proudly: use UVLED to study the variation of semiconductor silicon molecules under ultraviolet rays. It is said that it is possible to be possible Growing. Why not use traditional ultraviolet rays? Such as mercury lamps or halogen lamps? Because the growth of semiconductor silicon molecules must strictly control the amount of irradiation and temperature, only one of the variables change can the exact research conclusion be obtained.

1. Storage moisture-proof is very important for the normal use of LED lamp beads. In any case, LED lamp beads should be stored in a dry and ventilated environment. The storage temperature is -40 100 . It is better to use LED lamp beads within 3 months under its original packaging conditions, so as not to rust the bracket. When the packaging bag of LED lamp beads is opened, it should be used as soon as possible. At this time, the storage temperature is 5 28 , and the relative humidity is 60%as follows. 2. Cleaning can not use unknown chemical liquid to wash LED lamp beads, which may damage the appearance of LED lamp beads and even cause collagen cracking. If necessary, soak the LED lamp beads at the alcohol at room temperature. Time should Stimulate within one minute. 3. Do not take shape during welding or after welding. Remember that any behavior of squeezing resin may damage the golden line inside the LED lamp bead. 4. When welding is welded with LED lamp beads, do not apply any external pressure to the lamp body. Otherwise, it may break inside the LED lamp beads, which will affect its internal golden wire connection and cause quality problems to cause quality problems. The colloid must not be immersed in the welding. When welding, the welding point must have at least 2 sisters from the lower edge of the colloid. If the LED lamp beads are uniformly launched with a soldering iron, do not weld the two pins of the uniform LED lamp beads at the same time. What else must be noticed is that the welding temperature or improper time control may cause LED lamp bead lenses deformation or the internal opening of the core of the lights and cause the dead lamp. 5. It is recommended to use the essentials in the process of use, whether it is single or multiple in use, the driver current of each LED lamp bead is recommended to use the IF range. The instant pulse will destroy the internal fixed connection of the LED lamp bead, so the circuit must be carefully designed, so that when the online road is closed, the LED lamp beads will not be impacted by overvoltage (overcurrent) shock. LED lamp beads require the consistency of light and brightness and color when used in multiple uses. Under normal conditions, the consistency of the color of the LED lamp beads and the brightness of the brightness. 6. The protective static electrostatic static electrostatic can cause LED lamp beads to effectively lose effect, so during the use process, it is necessary to avoid the damage to LED lamp beads. 1. LED lamp bead detection and assembly must wear static uniforms and anti -static gloves. 2. Welding equipment and testing equipment, tables, storage racks, etc. must be used for use. Three imported LED lamp beads, using ionic fan to eliminate LED lamp beads during storage and assembly during storage and assembly. Fourth, the ingredient box containing LED lamp beads uses anti -static ingredients, and the packaging bag uses a static bag. The phenomenon of LED lamp beads damaged by electrostatic damage will appear: 1. Inverse leakage, light will cause a reduction in brightness, and in severe cases, the phenomenon of death will occur. Second, the voltage value becomes smaller. LED lamp beads can't shine during low -current driving.

1. The storage conditions of the light oil on the UVLED ink and UVLED are generally: low temperature state, cool and ventilated, or can be stored in the refrigerator. Their shelf life is generally 1 year. If the storage conditions of the above requirements are not met, it is easy to deteriorate and cause material damage. 2. When the UVLED ink or optical oil is applied, the coating should not be too thick and too thin, and it is easy to cause the material and the printing to not be well combined. 3. UVLED ink and upper optical oil cannot be mixed with ordinary ink or upper optical oil. If the material is used to convert from ordinary materials to UV materials, the material should be cleaned with the machine. And the auxiliary agent can only use the UV -specific auxiliary agent. 4. UVLED ink and upper optical oil should use professional cleaning agents such as: acetic acid, ethanol, etc., and our commonly used gasoline and kerosene can not work. 5. Avoid contact with the skin, it will cause itching, redness, pimples, peeling and other symptoms. In case of sticking to the skin, it should be cleaned with soap as soon as possible. (Note: Ethanol acetic acid can be cleaned, but they are not commonly used in life, so in emergency situations, soap is best found) 6. The attachment of UVLED ink And changes, so when a new printing is printed, it should be confirmed first. 7. The black ink in the UVLED ink has a strong ability to absorb ultraviolet rays. Therefore, the curing speed of such ink is slower. During the printing process of UV black ink, it is necessary to slow down the printing speed. The purpose is to increase the time of ultraviolet rays. Make the ink sufficiently solidify.

Directly inserted LED lamp beads in the process of welding, please strictly abide by the following requirements: 1. Be sure to wear anti -static gloves, anti -static wrists, etc. during actual production. Only lead. Because the humidity of the human body on the workbench is 60%-90%, the static electricity of the human body will damage the crystal layer of the LED lamp beads. After a period of time, the LED lamp beads will show failure and dead lamps. 2. Welding temperature is 260 C, 3 seconds. Too high temperature and too long will burn bad chips. In order to better protect the LED lamp beads, LED lamp beads and PC boards should be kept at a distance of more than 2mm to make the welding heat dispel. 3. The normal operating current of the direct -inserted LED lamp bead is 20mA, and the micro fluctuations of the voltage will cause a large fluctuation of the current. Therefore, during the design of the circuit design, different current -limiting resistors should be paid according to the voltage and deployment of LED lamp beads to ensure that the LED lamp beads are in the best working state. When the current is too large, the LED lamp beads will shorten the life, the current is too small, and the required brightness requirements cannot be met. Our company will split the LED lamp beads when batch supply, that is, the LED lamp bead parameters in the same pack of products are consistent, ensuring the consistency of the actual product. At present, the more common LED lamp beads welding method: 1. Single iron welding: the tip of the tip of the soldering iron does not exceed 300 C, the welding time does not exceed 3 seconds, and the welding position is at least 2mm from the colloid. 2. Summit welding: The maximum temperature of soaking welding is 260 C, the welding time does not exceed 5 seconds, and the soaked welding position is at least 2mm from the colloid. Directly inserted LED lamp bead welding curve pins method: 1. Must be 2mm from the collagen to bend the bracket. 2. The formation of the bracket needs to ensure the pins and spacing consistent with the line board. 3. The formation of the bracket must be done with a fixture or by a professionals. 4. The formation of the bracket must be completed before welding.
