Hubei UV aging box

Hubei UV aging boxArtificial accelerated aging test, also known as environmental testing, is commonly involved in the aging of polymer materials such as rubber, plastic, coatings, inks, and resins during use. Aging refers to changes in the properties of polymer materials caused by changes in environmental conditions, such as discoloration, powdering, loss of luster, and decreased strength.

But how do we evaluate the aging resistance of polymer materials? In production and scientific research practice, people have gradually developed two methods for evaluating aging: one is the natural aging test method, which directly uses the natural environment for aging testing, such as the natural exposure test; The second method is the artificial accelerated aging test, which involves using various aging test chambers in the laboratory to simulate certain aging factors and conditions related to natural environmental conditions.

Due to the diverse factors that cause polymer aging and the complexity of polymer aging mechanisms, natural aging is undoubtedly a reliable and important aging test method. However, due to the generally long cycle of natural aging testing, the experiment is too slow; In addition, the significant differences in climate conditions among different regions, years, and seasons have led to poor comparability of the results of natural aging tests. If artificial accelerated aging tests are adopted to simulate and strengthen certain important factors in the natural environment and climate, such as temperature, sunlight, rainfall, etc., it will undoubtedly greatly shorten the cycle of aging tests on the test subjects. More importantly, due to the controllability of the test conditions, the reproducibility of the test results is strong.

Artificial accelerated aging test, as an important supplement to natural aging, is increasingly widely used in the research, development, and testing of various polymer materials, and has become a substitute for natural exposure testing in general industrial and mining enterprises and research institutes.

The production process of Hubei UV aging chamber and UV aging test chamber is briefly described as follows:

Firstly, the selection. To determine whether it is a tower type UV aging test chamber or a box type UV aging test chamber, it depends on the customer's testing requirements. If only performing photo aging to test the photo aging performance of materials without the need for spray function, this desktop is better. If all functions, such as lighting, spray, heating, etc., are required, then,Be sure to choose a vertical fully functional UV aging test chamber.

Secondly, it is necessary to know what control instruments to use. There are pure button type, ordinary touch screen instruments and other instruments, of course, the price varies depending on the instrument.

Thirdly, start sheet metal fabrication. Once the instrumentation and control system are finalized, sheet metal can begin production. Sheet metal production requires attention to the position of instrument openings and the quality of welding parts to ensure that they are not damaged

Can leak water or air.

Fourth, paint. After the sheet metal is completed, start spraying paint. adopted304The shell is made of stainless steel, but in order to ensure(Because stainless steel is also "stainless" for certain environments)Still need to do paint,

Of course, painting also has an aesthetic effect.

Fifth, electrical installation. This part is a reflection of a company's technological strength, and it is also the reason why each company produces different UV aging test kits according to the same standards, because

In terms of implementing a specific function of the UV aging test chamber, different electrical controls can be used, which vary greatly depending on the technical characteristics and cost considerations of each company. However, no matter how vastly different, quality and performance must be guaranteed.

Sixth, install water tanks, light tubes, sealing strips, etc. The sealing issue is a technical detail that many small manufacturers overlook and do not know, so some of them do not even encrypt the sealing strip. It's a bit that the sealing strip is not encrypted at all

It cannot resist ultraviolet rays(We also produce our own UV aging test chamber!),As a result, customers using these sealed products will soon corrode circuit boards and instruments due to water vapor leakage.

Seventh, test the machine.

Eighth, packaging and transportation. The packaging should be ensured not to be damaged or exposed to rain.
