The Problem of Oxygen Resistance Polymerization of UV Curing
The problem of oxygen resistance of curing materials in liquid form, oxygen in the air will diffuse among them.
Ultraviolet Curing
The photoinitiator can triggere the wavelength determines.The irradiance determines the initiation efficiency of ultraviolet curing light.It directly affects the surface dry (anti-oxygen polymerization) and deep ultraviolet curing effect.And the radiation dose determines whether the ultraviolet curing can be carried out thoroughly.We first inquire about the type of photoinitiator for the materia.We want to cure and choose the best UV light source with peak wavelength.Absorption intensity of different photoinitiators for 365nm wavelength.https://tank007.comproduct-category/uv-flashlight/ initiation efficiency of ultraviolet curing light
Factors affecting of ultraviolet curing
The optical characteristics of UV light source on the photochemical reaction degree of photoinitiator has an important impact.
The Ultraviolet Curing Process
First, we need to understand the components of the curing material and the ultraviolet curing process.
What is ultraviolet curing?
Ultraviolet curing is the most common and mature industrial application of UV.But also occupies the largest market size.Currently it mainly uses in curing UV wavelength of UVA.Curing refers to the process of material from low molecules to polymers.Ultraviolet curing refers to the UV light irradiation.To make the curing material in a short time of photochemical reaction.As well as making the adhesive from liquid to solid in a few seconds. In the curing field, accounting for a large proportion of industrial curing applications.Such as building materials coating, coating of electronic products and other curing.These curing equipment are large, for the consumer [...]
Why UV Flashlight is Purple Light?
The UVA uv spectrum is mainly between 360nm-400nm at present.
Why is Inproved TK566 UV Flashlight so Popular?
No matter interested in antique identification, but introducting to the friend recommended this brand.
What is UVC?
UVC (280nm-200nm): short wavelength with the weakest penetrating power.
What is UVB?
UVB (315nm-280nm): Medium wavelength with medium penetration, its shorter wavelength part will be absorbed by transparent glass.
What is UVA?
UVA (400nm-315nm): UVA has the longest wavelength and strongest penetrating ability.
The wavelength of ultraviolet rays
Since the ultraviolet rays radiation with a wavelength less than 200 nanometers will be strongly absorbed by the air, we basically only study ultraviolet rays with wavelengths above 200nm in our applications.
Ultraviolet radiation
The current national standard in China is according to Article 845-01-05 of GB/T2900.65-004 "Electrical Terminology Illumination".
