Application And Working Principle Of UV Accelerated Testing Chamber
Purpose and working principle:
Using fluorescent ultraviolet lamp as light source, the accelerated weather resistance test of materials is carried out by simulating ultraviolet radiation and condensation in natural sunlight, so as to obtain the results of weather resistance of materials. It can simulate the environmental conditions such as ultraviolet, rain, high temperature, high humidity, condensation and darkness in the natural climate, reproduce these conditions, combine them into a cycle, and let it automatically execute the number of cycles. It is mainly used for non-metallic materials and organic materials (such as coatings, paints, rubber, plastics, and their products) to test the aging degree of relevant products and materials under the change of climatic conditions such as sunlight, temperature, humidity and condensation. Get discoloration, fading, etc. in a short time.
The UV accelerated testing chamber is applicable to the performance reliability test of a variety of industrial products, Refer to 《GB / T14522-93 national standard of the people's Republic of China - Plastics, coatings and rubber materials for mechanical industrial products - Accelerated artificial climate test method》, 《GB / T16585-1996 national standard of the people's Republic of China - artificial climate aging (fluorescent ultraviolet lamp) test method of vulcanized rubber》 and 《GB / T16422 3-1997 plastic laboratory light source exposure test method and other corresponding standard terms》
The UV accelerated testing chamber can reproduce the damage caused by sunlight, rain and dew. The equipment carries out the test by exposing the material to be tested to the controlled interactive cycle of sunlight and moisture and increasing the temperature at the same time. The equipment adopts ultraviolet fluorescent lamp to simulate sunlight, and can also simulate the influence of moisture by condensation or spraying. It is a necessary test equipment in aviation, automobile, household appliances, scientific research and other fields. It is suitable for schools, factories, military industry, research institutes, etc.
The chamber body of the UV accelerated testing chamber is processed and formed by NC machine tool, with beautiful and generous shape. The box cover is a two-way flip type, which is easy to operate.
The inner tank of the chamber is made of imported high-grade stainless steel plate, and the outer tank of the box is sprayed with A3 steel plate, which increases the appearance texture and cleanliness of the UV accelerated testing chamber.
The heating mode is tank tank heating, with fast temperature rise and uniform temperature distribution. The drainage system uses vortex return and U-shaped sedimentation devices for drainage, which is convenient for users to clean.
The UV accelerated testing chamber adopts black aluminum plate to connect the temperature sensor and blackboard temperature instrument to control the heating, which makes the temperature more stable.
The radiometer probe is fixed without loading and unloading each time.
The radiation amount adopts a special ultraviolet radiation meter with high-precision display and measurement.
The radiation degree of ultraviolet climate resistance test chamber shall not be greater than 50W / m.
Illumination and condensation can be controlled independently and alternately.
The independent control time of illumination and condensation and the time of alternating cycle control can be set arbitrarily within 1000 hours.
