Sunlight , UV , & Accelerated Weathering
Sunlight is an important cause of damage to plastics, textiles, paints, and other organic materials. Short wavelength ultraviolet light has long been recognized as being responsible for most of this damage2. Spectroradiometric measurements were made to quantify the wide variations in UV content of sunlight under the following conditions: direct summer sunlight, winter sunlight, sunlight filtere...
متن کاملstaining behavior of an anti-graffiti polyurethane clear coating against accelerated weathering test
apermanent anti-graffiti clear polyurethane coating, using a silicone additive, was prepared and studied. various techniques, such as contact angle measurements and edx were employed to characterize and investigate thesurface properties of the coatings. the results revealed that with inclusion of silicon additive to clear coating, according to wu method, surface free energy was decreased from 4...
متن کاملMethodology of accelerated weathering test through physicochemical analysis for polymeric materials in building construction
Physicochemical analysis in the microscopic sense is a critical assessment of monitoring the polymeric materials under a weathering test, and it links the accelerated laboratory test with the outdoor performance results for a long-term durability. Here, by taking an experimented example for vinyl siding after an outdoor weathering test in Okinawa, Japan for 17 years and a QUV accelerated weathe...
متن کاملEvaluation of anticorrosion behavior of automotive electrocoating primers by the AC-DC-AC accelerated test method
A protective coating has been applied onto the phosphated panels using cathodic electrocoating in two different dry film thickness namely 8µm and 20µm. The corrosion resistance of cathodic electrocoatings has been studied using AC/DC/AC method. Twelve cycles of AC/DC/AC test were carried out on each sample which the DC voltage of the first 6 cycles were -4 V VS. Ag/AgCl @ 20 minutes followed by...
متن کاملA Short Term, Accelerated Test Method for Rotary Compressors
Compressor reliability and durability testing has historically required significant time and a variety oftest methods, including basic materials and lubricants testing using Falex test methods or equivalent, long term compressor bench tests, end product reliability tests and final field trials before production release. Reducing the total design cycle time to a minimum, while maintaining a high...
