Ultraviolet aging test chamber

Ultraviolet aging test chamber


​To simulate the harm caused by sunlight, the testing machine used fluorescent ultraviolet lamps to simulate the effect of sunlight exposure. The tested material is placed in the light at a certain temperature for testing. Hazards that occur outdoor for months or years can be recreated in days or weeks. Types of hazards include: color fading, discoloration, loss of light, power light, cracking, peeling, turbidity, bubbles, brittle, reduced strength, decay and oxidation. It’s widely used in coating ink pain, resin, plastic, printing packaging, adhesives, automotive and motorcycle industry, cosmetics, metals, electronics, electroplating and pharmaceutical industries.



UVA lamp

Use to compare with different polymers, because uv lamp no uv element below 295nm, dislike the UVB lamp can degenerate rapidly materials, The test will be closed to the outdoor results.

UVA-340

Wavelength between 365nm and 295nm, peak wavelength in 340nm, use to compare the formulas of different samples.

UVB lamp

It gives of the unnatural light, wavelength below in 295nm, as test results, it is fatter than uv lamp, widely use in QC and testing durable materials. The test results were somewhat different those outside. There are two UVB lamp to use with same wavelength, the total uv content is different.
