How to choose the correct fixture for UV Aging Test Chamber?

UV Aging Test Chamber is used for non-metallic materials and rubber products, etc., in the exposure to a closed and contains a certain amount of ultraviolet light in the environment, resulting in cracking aging test, so it should be complete inside the configuration, and there can not be any loose situation, on the test machine fixture, for example, because of the special characteristics of the fixture structure, the user in the selection of UV Aging Test Chamber should pay attention to the following four aspects.

 

1, the tooling fixture to maintain the degree of reliability, can not have all the runaway condition, the application should be convenient, security;

 

2, for must be done in the outdoor high temperature natural environment of the experiment, fixture provisions are very high, not only heat resistance, UV resistance, not deformation, volume to be small;

 

3, for the deformation of large raw materials, because the deformation is too large, so the clamping is difficult, the design of the fixture is a difficult problem; for high frequency, large quantities of large experimental products, overseas manufacturers and customers choose automatic clamping, Chinese manufacturers and customers can also choose automatic clamping, to save time

 

4, UV Aging Test Chamber due to high hardness of steel wire, steel strand specimens, the internal structure is relatively loose, uneven force during the tensile test, clamping specimen jaws easy to wear and other reasons, UV aging test chamber fixture has not been a good solution, the past is the use of clamping aluminum foil to do, a test will cost four pieces, a lot of waste; now the use of spray diamond type The problem of slippage has been solved, but the fracture position has not been ideal, so manufacturers have been using new methods to improve the performance of the fixture to improve the quality of test products.

 

 

How to check the uv outside?

QUV aging chambers allow samples to be exposed alternately to cycles of UV light and condensation, at controlled temperature, In a few days or a few weeks, you get the results of a natural aging of several months or years.
