There are many manufacturers of ultraviolet aging test chambers on the market, and their respective test chambers have proposed their functions and application scope. So what are the functions of the ultraviolet weather resistance test box in the practical sense?
The emergence of the ultraviolet aging test chamber has provided many manufacturers with convenience and reliability to improve product quality. Therefore, for manufacturers, the aging resistance and light resistance of the products are extremely important. The ultraviolet weather resistance test chamber can simulate the strongest ultraviolet radiation in summer. It is widely used in: paints, inks, paints, resins, rubber, plastics, Printing and packaging, adhesives, automobile and motorcycle industry, petrochemical industry, cosmetics, metal, electronics, electroplating, medicine, textile and other industries, refer to the plastic ultraviolet lamp light source exposure test method GB9344-88 and GB / T9276-96 "coating color "Design of paint and varnish test".
Working principle of UV aging test box: For durable materials exposed outdoors, the short-wavelength of UV 300 ~ 400nm is the most important cause of aging damage. In the ultraviolet short-wave region, the most natural simulation of the damage caused by ultraviolet aging on the product.
(Note: Climate and sunlight exposure are the main causes of damage to paints, plastics, inks, and other polymer materials. Such damage includes loss of gloss, discoloration, yellowing, cracking, peeling, embrittlement, reduced strength, and delamination. Even Both indoor light and sunlight projected through glass windows will also cause some materials to age, such as causing fading or discoloration of pigments and dyes.)
As a result, the damage of ultraviolet rays is quite large, and the damage to human social products is self-evident. This requires the majority of product manufacturers to recognize this actual situation, improve their product quality, and thereby enhance the competitiveness of enterprises and promote The enterprise has grown stronger.
Survive by quality, develop by credibility, and always meet contract requirements and potential needs.
