UV energy meter and UV related knowledge

The standard UV energy meter (UV-Integrator150) is a high-quality UV energy measuring instrument for measuring the energy of an ultraviolet UV exposure device. The main sensor of the measuring instrument is on the back of the measuring instrument and the measuring range is 250. ~ 410 nm, can be directly displayed on the front of the UV energy meter when reading (in milli-Joules/cm2). The power of this UV energy meter is a 3.6 volt lithium battery. The energy saving circuit, the battery lasts about hours.

The following is UV related knowledge:

UV is the English abbreviation of Ultra-Violet Ray.

Industrial UV wavelengths range from 200 nm to 450 nm for their applications. The UV-curable material is irradiated with UV to harden it, which is called "UV Curing Process".

A. UVB, UVA, UVV, UVC

In the industrial UV wavelength range of 200 - 450nm (fan4 wei2), we divided it into four areas: UVA: 320 - 390 nmUVB: 280 - 320 nm UVC: below 280 nm UVV: 390 nm or more

B. Curing

Curing is "hardened" (or "cured"). In the UV Curing Process, the liquid "UV-irradiated hardenable material" is instantly processed by the UV to become solid (Chun bian cheng gu) process called "Curing". Hardening "Curing" and traditional (_yu chuan tong The drying "Drying" process is similar but not identical. The difference is that the dry process solvent-free erode-hardening process is solvent-free (hair hua jia gong guo cheng ze wu rong ji de hui) .

C. Why Use UV Curing Process (UV Hardening Process)

1, can reduce energy waste

2, there will be no solvent Volatile air pollution

3, shorten the process time to improve production efficiency

4, the required equipment space can reduce the investment cost of the plant

5, due to the process to shorten the quality and easy to control the product yield can be greatly improved.

D. How to use UV hardening process

UV hardening process we can see it as a tool for product processing This tool includes "UV radiation hardenable material" ç…³ "UV light source" and smear equipment. For users of different needs to first select "UV Irradiation of hardenable material" Design the smearing device and appropriate UV light source according to the special name of the material.

E. UV irradiation hardenable (zhao she ke ying hua) material

The UV radiation hardenable material may be a paint varnish ink or adhesive. Among them are: 1. Monomer. 2. Prepolymer. 3. Photoinitiator. 4. Additive. Pigments or dyes (ink).

F. Hardening principle of "UV radiation hardenable material"

Photoinitiators in UV-irradiation hardenable materials absorb light at certain wavelengths in the ultraviolet spectrum (wavelength 200-400nm) and generate broken bonds. These broken bonds then strike the monomer and prepolymerize the chains. The bridging reaction instantaneously changes the material from liquid to solid.

G. How to choose "UV radiation hardenable material"?

This problem should be answered by the industry itself because only the industry itself knows what to do with clear goals before looking for appropriate material suppliers to discuss in order to choose the right UV radiation hardenable material.

H. What is a suitable supplier of UV materials (UV-related knowledge)

The application of UV hardening process is very extensive. Different products have different requirements in their manufacturing process. Even the same products in different manufacturers' factories may have different manufacturing processes. Each UV material supplier is unlikely to produce UV materials. Responds to all different product requirements but each UV material supplier bowl develops some good products for some of the products it concentrates on. The manufacturer can UV-harden for the needs of UV suppliers who provide suitable UV materials. The various benefits of the process.

I. How to choose a UV light source after finding a suitable UV hardening material?

Each UV material supplier of course knows that the most important of the UV materials they provide is to meet the “hardening conditions of each UV material” (Cai2 Liao4 de0_ying4hua4tiao2jian4). The user can select the appropriate UV light source for this hardening condition after having this hardening condition.

J. What is "shen me shi ying hua tiao"?

The main hardening conditions for hardened UV materials are: 1. UV illumination (blank) => lamp output intensity mirror design illumination distance coating thickness. 2. UV cumulative energy => production efficiency temperature. UV spectrum distribution => Selection of lamp types. The "UV light" irradiation UV material provided by the appropriate combination of the above three factors makes the UV material harden to meet the requirements of the manufacturer's product specification. We call this "UV light" suitable "Cure conditions".

K. What kinds of UV light sources are available on the market (UV related knowledge)

Generally speaking, there are two types of light sources used to harden UV hardening materials: (1) Arc UV Lamp (2) Electrode-less UV Lamp.

L. Electrode type UV light source (Arc UVLamp)

Electrode-type UV light source whose lamp tube is evacuated by a quartz tube and then injected with a certain amount of mercury or filler metal fittings connected to the power supply. Features: 1) Lamp length from 4 inches to (ying cun dao) 90 inches 2) Lamps are generally cheaper than the surname 3) Unit strength: 200 W/inch; 300 W/inch; 400 W/inch 800 W/inch. 4) The equipment is cheaper.

M. How to find a suitable UV process?

A suitable UV process is for the industry to improve its production efficiency and increase its product's yield to allow its products to be more competitive in the market. Therefore, users or manufacturers can know how to arrange UV processes on their production lines. On the UV equipment manufacturers can only provide a UV source that can be compatible with the manufacturer's production line. Of course, this UV light source is to be able to correct and stable hardening of the UV materials selected by the supplier. As for the supplier of UV materials also Designed to meet the industry's need to design materials that meet industry requirements and provide a condition to harden this material for UV equipment manufacturers to reference. In short, a suitable (UV) process must be the manufacturer's UV equipment manufacturing Solicitation of the opinions of the suppliers of UV materials.
