Ordinary fly ash type C is modified the surface by the agents KOH 3M, Silane Silquest in acidic condition pH = 4 and Stearic acid 2 , respectively. Mixture of bisphenol A epoxy resin GELR 128 resin A and Bisphenol F epoxy resin EPOTEC 170LV F resin is prepared by agitating well in a glass with a agitating speed of 200 rpm at a temperature of 50°C and a time...

Analogy of Some Physicomechanical Properties for Rubber Cement
Team IJTSRD
May 31, 2019
0
The research is aimed to characterize and apply the rubber cement. The physicomechanical properties of rubber cement such as tensile strength, elongation at break, waste uptake and compression percent were determined by standard rubber testing. Tensile strength of 28 to 32 kg cm2, elongation at break of 580 to 630 , water uptake 24 hours of 8 to 10 and compression...

Characterization of Polymer Composite Materials Based on Epoxy Resin GELR 128 Modified with Epoxidized Sunflower Oil Cured by 4.4'-Diaminodiphenylmethane
Epoxidized sunflower oil (ESO) is used to modify the epoxy resin GELR 128 for increase the toughness of epoxy resin. ESO mixed with epoxy resin at different concentrations by one-stage and two-stage process. Epoxy resin GELR 128 and epoxidized sunflower oil were cured by aromatic amine curing agent (4.4'-diaminodiphenylmethane (DDM)). Morphology, physico...

Technological Progress from Ancient Stone Age to Recent Polymer Chemistry World
Technological artifacts are products of a society's economy, a force for economic growth, and a large part of everyday life. Technological innovations affect, and are affected by, a society's cultural traditions. The invention of tools and techniques is evidence of a society's ability to solve problems that were encountered in everyday life. Many sociologists...
