Evaluating the Performance Through the UV Aging Test Chamber: Emerging Trends in the Market

Through the test of the UV aging test chamber, the performance change of the material under different ultraviolet radiation can be evaluated, such as the color change of the material, the change of the surface quality, the change of physical properties, etc., so as to carry out the development and improvement of subsequent products. Widely used in plastics, coatings, rubber, textiles, cosmetics, auto parts and other fields.

The principle of UV aging test chamber:
The damage to materials caused by natural sunlight and moisture causes inestimable economic losses every year. The UV aging test chamber can reproduce the damage caused by sunlight, rain and dew. The equipment is tested by exposing the material to be tested to a controlled alternating cycle of sunlight and humidity while increasing the temperature.

The device uses ultraviolet fluorescent lamps to simulate sunlight, and can also simulate the effect of moisture through condensation or spraying. In just days or weeks, devices can reproduce the damage that takes months or years outdoors. The damage caused mainly includes fading, discoloration, brightness reduction, powdering, cracking, blurring, embrittlement, strength reduction and oxidation.

The test data provided by the equipment can be extremely helpful in selecting new materials, improving existing materials, or evaluating compositional changes that affect product durability. Devices are excellent at predicting the changes a product will encounter outdoors. the

Simulation of ultraviolet light (uv) and sunlight, although ultraviolet light (uv) only accounts for 5% of sunlight, it is the main lighting factor that causes the durability of outdoor products to decrease. This is because the photochemical influence of sunlight increases as the wavelength decreases. Therefore, when simulating the destructive effect of sunlight on the physical properties of materials, it is not necessary to reproduce the entire sunlight spectrum. In most cases, it is only necessary to simulate short-wave UV light. the

The reason why UV lamps are used in ultraviolet aging test chambers is that they are more stable than other lamps and can better reproduce test results. Using fluorescent uv lamps to simulate the impact of sunlight on physical properties, such as brightness drop, cracking, peeling, etc., is the best method.

There are several different uv lamps to choose from. Most of these uv lamps primarily produce ultraviolet light rather than visible and infrared light. The main difference between the lamps is the difference in the total UV energy they generate in their respective wavelength ranges. Different lamps will produce different test results. The actual exposure application environment can prompt which type of UV lamp should be used.

The future development prospect of UV aging test chamber is very broad. According to a market research report, the global UV aging test chamber market will grow at an average annual rate of 6% in the next few years. This is mainly due to the following factors:

1. Increased demand in the food, beverage and medical industries: These industries have high requirements for high quality, stability and durability of products, so they need to use UV aging test chambers for product testing and verification.

2. The growth of the electronic industry: With the continuous development of technology, more electronic products have entered our lives. These products have high requirements on UV aging, and manufacturers need to use such test chambers to verify the quality and reliability of electronic products.

3. The promotion of environmental protection policies: Environmental protection policies will become more stringent, and manufacturers need to test their products more rigorously to ensure compliance with environmental standards. These test chambers provide very accurate test results, allowing manufacturers to know which environmental standards their products meet.

The UV aging test chamber adopts the research of new principles, new materials and new technologies, so that it is more in-depth and extensive, and new varieties, new structures and new applications are constantly emerging. The development of five major trends will be the focus.
1. Intelligence: implement the integration of various detection functions and data processing, storage, two-way communication, etc.;

2. Informatization: through the due development of information technology and the use of enterprise information resources, the process of improving management level, development ability and operation level to enhance the competitiveness of enterprises;
3. Energy-saving: research and development of green energy-saving products, green energy-saving is the mainstream of development in today’s society;

4. Integration: multi-functional integration has attracted widespread attention;
5. Diversification: The breakthrough of new material technology has accelerated the emergence of many new types of equipment.

UV aging test Chamber is designed for evaluating the resistant performance of non-metallic materials, organic materials (plastics, paints, coatings, rubbers, etc.) under the specified conditions such as sunlight, temperature, and other climatic conditions. It creates a man-made testing environment imitating the natural light source such as sunlight and other damages in the nature, such as rain and dew damage, to impose on the materials and to assess the degree of color changing and fading under the accelerated environment conditions. The chamber fully complies with the requirements of Standard ISO 4892-1, ISO 4892-3, GB/T16585-1996, GB14522-93, GB/T16422.3-1997, ASTMG53 and etc., provides the best UV sunlight simulation, and is easy to use and operate.
