The corrosion resistance of waterglass-based putties is influenced considerably by the alkali modulus. The acidresistance of such putties is currently tested according to the standard DIN EN 993 – 16 and described by means ofthe measured change in weight. Dynamic Mechanical Analysis (DMA), a testing procedure to define the viscoelasticbehavior of plastic materials, has brought about new findings on evaluation of the influence of the alkali modulus andthe kind of damage resulting from corrosio...The corrosion resistance of waterglass-based putties is influenced considerably by the alkali modulus. The acidresistance of such putties is currently tested according to the standard DIN EN 993 – 16 and described by means ofthe measured change in weight. Dynamic Mechanical Analysis (DMA), a testing procedure to define the viscoelasticbehavior of plastic materials, has brought about new findings on evaluation of the influence of the alkali modulus andthe kind of damage resulting from corrosion caused by acids, with regard to mechanical behavior. Both applied testmethods have revealed two different effects of corrosion: weight loss on the one hand, and a decrease in the storagemodulusEI, on the other hand.» weiterlesen» einklappen
