Influence of Natural Filler

EPDM Composites filled with Corn Starch and thermoplastic Starch

In den letzten Jahren ist die chemische Industrie auf die Erforschung und den Einsatz von natürliche Quellen ausgerichtet, z. B. von Lignin, Cellulose und Stärke. Eines der Hauptprobleme für Gummiprodukte ist durch den konstant anwachsende Gummiabfall verursacht, dessen Deponierung und dem Mangel an Möglichkeiten der Reduzierung. Es wurde der Einfluss von natürlichen Füllstoffen auf den […] more...

PU-Coating of Steel Sheets

Wear resistance of steel sheets coated by Polyurethane reinforced by Nickel Chrome wires

Sand erosion of steel sheets coated by polyurethane and reinforced by nickel chrome (Ni Cr) wires of different diameters is discussed. The tested polyurethane composite coatings are proposed to defeat sand erosion of steel surfaces during dusty storms. Experiments have been carried out using sand blast test rig. Based on the experimental results, it was […] more...

Polyurethanes & Thermoplastics

Effect of Beta Irradiation on Mechanical Properties of Surface Layer of Injection Moulded High Density Polyethylene (HDPE)

The influence of beta radiation on the changes in the structure and selected properties (mechanical and thermal) polymers were proved. The specimens of high density polyethylene (HDPE) were made by injection moulding technology and irradiated by low doses of beta radiation (0, 33, 66, 99, 132, 165 and 198 kGy). more...
