How To Conduct Weather Resistance Test In Rotational Molding?
Roto-molding is a commonly used plastic processing method with good weather resistance. It can be used for a long time in outdoor environments without being affected.
In order to ensure that the weather resistance of roto-molded products meets the requirements, a series of weather resistance tests are required.
1. Appearance inspection
Appearance inspection is one of the intuitive inspection methods.
It can be observed by visual inspection whether there are cracks, fading, deformation, etc. on the surface of the product, and
whether the surface quality of the product meets the requirements.
2. Strength test
Strength test is to test the ability of the product to withstand stress in the external environment.
Through tensile, extrusion and other experimental methods, the strength of the product is tested to meet the design requirements, and it is ensured that it is not easy to deform or break during use.
3. Weather resistance test
Weather resistance test is to test the ability of roto-molded products to withstand the influence of natural factors such as sun exposure, rain, temperature changes, etc. under different environmental conditions.
Common weather resistance tests include ultraviolet exposure test, high temperature and humidity test, freeze-thaw cycle test, etc., through which the weather resistance of the product can be evaluated.
4. Chemical performance test
The weather resistance of the product is affected by chemical factors, so chemical performance test is required,
including the test of chemical stability, antioxidant and other indicators of the product, to ensure that the performance of the product in different chemical environments meets the requirements.
5. Aging test
The aging test simulates the situation that the product is exposed to the natural environment for a long time during use.
The weather resistance of the product in actual use is evaluated through accelerated aging test to ensure that its lifespan meets the requirements.
In summary, the weather resistance test of rotomolded products is an important link to ensure its quality and performance. Only through comprehensive inspection by multiple methods can the long-term stable use of the product in outdoor environment be guaranteed. When Foshan rotomolding is conducting weather resistance test, it is necessary to select appropriate test methods based on actual conditions, comprehensively evaluate the weather resistance of the product, and ensure that its quality meets the standard requirements.
