SOME FORMS ABOUT UVA CURING TECHNOLOIGY

UV curing is a process of chemical formula transformation from liquid to solid state by energy irradiation. Radiation curing mainly includes UV curing and electron beam curing. At present, UV curing is widely used in radiation curing technology, and the infrared curing energy is low, which makes it difficult to cause the short chain crosslinking reaction of molecules. EB curing has been limited due to its large equipment investment.

1、 Radiation curing

Radiation curing is a process of chemical formula transformation from liquid to solid state by energy irradiation. Radiation curing mainly includes UV curing and electron beam curing. At present, UV curing is widely used in radiation curing technology. EB curing is limited by its equipment investment. Therefore, the UV light is the main use of the photocuring.

2、 UV curing

The basic principle of UV curing is that the photoinitiator absorbs light of a specific wavelength by ultraviolet rays, and generates free radicals or cations, which leads to polymerization and cross-linking reaction between monomer and oligomer, and generates polymer with mesh structure in a very short time, and then solidify.

3、 UV LED curing industry chain

UV curing LED industry chain mainly includes raw material supply, curing equipment supply, chemical formula and downstream users.

UV curing raw materials are mainly by-products of petroleum processing. It mainly includes monomer, oligomer, photoinitiator and auxiliary (such as leveling agent, defoamer, wetting agent, smoothing agent, light eliminator, stabilizer, pigment, solvent, etc.). Oligomers are the basic skeleton of light curing materials, and the properties determine the main properties of the substrate coating after curing (hardness, flexibility, adhesion, optical properties, aging resistance, etc.); monomer is used to dissolve and dilute oligomers, which will affect the reaction rate of photocuring and the performance of final film; photoinitiator is the key material in the photocuring system, although the dosage is small, but it is used as the main material But it is very important to determine the curing speed and quality.

Chemical formula products mainly refer to coatings, inks and adhesives, which provide material basis for UV curing application of end users.

Curing equipment refers to the equipment and equipment link for the curing process, mainly including the supply of UV LED devices, modules and other light sources.

Downstream users, the light curing materials are widely used in wood, plastic, paper, metal and other substrates, mainly used in printing, plastic coating, packaging, automobile, home, 3D printing, electronic components, medical and other fields.

What is the concept of heat pipe?

A: heat pipe: it is a kind of artificial component with excellent heat transfer. The commonly used heat pipe consists of three parts: the main body is a closed metal pipe, with a small amount of working medium and capillary structure inside. The air and other sundries in the pipe must be excluded

How does the heat pipe work?

Answer: three physical principles are used in the heat pipe operation: 1) in vacuum, the boiling point of liquid is reduced; 2) the latent heat of vaporization of the same substance is much higher than the apparent heat; 3) the suction force of porous capillary structure to liquid can make the liquid flow

What is a heat pipe radiator?

A: heat pipe radiator: a new product produced by the use of heat pipe technology to make significant improvements to many old-fashioned radiators or heat exchange products and systems

What is the concept of thermal conductivity?

A: "thermal conductivity": is a measure of the thermal conductivity of a substance. The symbol is λ or K. It is defined as: two parallel planes with a distance of 1 m and an area of 1 m2 are taken in the direction perpendicular to the direction of heat conduction in the object. If the temperature difference between two planes is 1K, the heat transmitted from one plane to the other in one second is defined as the thermal conductivity of the substance

What is the thermal conductivity of several commonly used metals?

Answer: beryllium thermal conductivity: 200w/ (m · K) copper thermal conductivity: 397w/m · K copper thermal conductivity: 407w/ (m · K) aluminum conductivity: 238w/ (m · K) tin thermal conductivity: 67W / m.k iron thermal conductivity: 40 × 1.163w/ m.k

What are the application scope of heat pipe?

A: heat pipe is widely used in spacecraft, engine, CPU, telecommunication equipment, LED lamps, agricultural appliances, etc

What are the classification methods of the bulb?

A: 1. tungsten filament bulb, including incandescent bulb, quartz bulb and halogen bulb, etc.e-edison (Edison screw port); b-bayonet (bayonet). 2. common quartz bulbs include type T (JC), Mr, jdr-c (GU10). 3. fluorescent lamp, commonly used FL (T5, T8, T12...) , PL-S, pl-c, 2D and energy saving lamp

What are the treatment methods for aluminum surface?

A: anodizing, electroplating, painting, drawing, polishing, etc

Which of the several commonly used metal materials has the best thermal conductivity?

A: copper (phosphor, copper, brass, red copper)
