Now is an Internet age, many things can be operated directly on the Internet. The Internet makes people’s life more and more convenient, and this requires very high network speed, and optical fiber can maximize the speed of the network. The curing of the fiber coating requires the use of [uvled light curing] technology. Today I will follow the small edition of Koinu Photoelectric to share this knowledge.

The fiber is composed of a core, cladding and coating. The typical core is pure silica glass or germanium-doped silica glass, while the cladding may be pure silica glass silica glass. The diameter of the core depends on the application of the fiber, and the cladding diameter is typically 125μm. The thickness of the polymer coating of the optical fiber is about 60μm. Therefore, the diameter of the fiber is 245μm. Among them, the inner coating is softer and the outer coating is harder. The inner coating is used to protect the surface of the bare fiber from mechanical damage and to buffer the external stress during the use of the fiber. The hard outer coating is conducive to the fiber wear resistance. When the fiber is fused and joined, the coating must be removed cleanly from the glass fiber surface. In order to be able to provide a coating that can be removed with very little force and no residue is left behind, it is necessary to understand the coating properties that affect strippability. To understand these effects, it is necessary to distinguish between the peeling force of the coating and the drawing force of the coating. The peeling strength of the coating is determined by the outer coating of the fiber. The pull force of the coating, that is, the bonding force between the inner coating of the fiber and the quartz glass cladding, depends on the inner coating of the fiber. In actual production, the curing of the outer coating basically reaches the saturation state, so it is necessary to control the UV curing dose of the inner coating of the fiber to ensure that the coating pull output of the fiber meets the requirements of the fiber specification. The basic components of UV-curable coatings are UV-polymerizable synthetic resins, photosensitizers, active diluents and some special additives. Photosensitizer, also known as UV polymerization initiator, is an essential component of UV curable coatings. The curing rate of the film depends largely on the variety and quantity of this component. Most of them are substances that are excited by light in the near ultraviolet region to produce free groups, and they are sensitive to light and stable to heat. During the coating process, the absorption of ultraviolet light can produce free radicals, which can trigger the crosslinking reaction of oligomer and diluent to form the film.

In the actual production, there are many factors affecting the curing of optical fiber, which is more complicated. There are several ways to measure the curing degree of UV cured acrylic coatings and the coating pull power of optical fibers. Some factors affecting the curing of fiber and the corresponding new energy of fiber are discussed. Generally speaking, UV-curable coatings are composed of high-viscosity prepolymers, low-viscosity monomers, photoinitiators and other fillers, which is a thixotropic fluid whose viscosity changes with temperature. The impact of UV curing equipment: UV curing equipment has its service life, and its light intensity will be weakened with the extension of the use time, which will affect the curing degree and curing quality of the fiber, and affect the fiber performance such as coating stripping force. Traditional UV lamps are very obvious in this respect, but as far as UVLED light curing equipment is concerned, the service life of UV point light source, light intensity and so on have been greatly improved. When using a UVLED light source as a luminous body, there is no need to worry about these reasons. LCM is LCD display module, liquid crystal module, which refers to the LCD display device, connector, control and drive peripheral circuits, PCB circuit board, backlight, structural parts and other components assembled together.

Very long life, the service life is more than 10 times that of the traditional mercury lamp curing machine, about 25,000 to 30,000 hours. Cold light source, no thermal radiation, the surface temperature rise of the illuminated product is low, to solve the long-term thermal damage problem of optical communication and liquid crystal production. Especially suitable for liquid crystal edge sealing, film printing and other occasions requiring small temperature rise. The heat output is small, which can solve the problem that the heat output of mercury lamp inkjet equipment is large and the staff is unbearable. Instant light, no preheating is required to achieve 100% power UV output immediately. The service life is not affected by the number of opening and closing times. High energy, stable light output, good uniform irradiation effect, improve production efficiency. It does not contain mercury and does not produce ozone, making it a safer and more environmentally friendly alternative to traditional light source technology.
The development of the Internet is a revolution, the Internet gives people a lot of opportunities, but also unconsciously change the people’s living habits. For many industries, the development of the Internet has ushered in its own opportunities. UVLED curing technology is linked to the development of the Internet through optical fiber.
