Reticulation of Aqueous Polyurethane Systems Controlled by DSC Method

Reticulation of Aqueous Polyurethane Systems Controlled by DSC Method

The DSC method has been employed to monitor the kinetics of reticulation of aqueous polyurethane systems without catalysts, and with the commercial catalyst of zirconium (CATXC-6212) and the highly selective manganese catalyst, the complex Mn(III)diacetylacetonemaleinate (MAM). Among the polyol components, the acrylic emulsions were used for reticulation in this research, and as suitable reticu...

Synthesis of Carbon Spheres of Controlled Size by Hydrothermal Method

Carbon Spheres were fabricated by hydrothermal method and their structural properties were investigated. Carbon Spheres with average sizes around of 230, 320 and 430 nm were synthesized in different concentration of glucose aqueous solution and different hydrothermal reaction time. The temperature of 180 °C by a hydrothermal reaction was fixed in all of glucose concentration and hydrothermal re...

Constant Exposure Method for DSC IGBT Strobe

A constant exposure method for DSC IGBT strobe is proposed. This method is based on two lookup tables (exposure and energy table). In this method, light box is used to generate exposure table and different flash time is used to generate energy table. Through exposure table and preflash result, we can get digital number ratio of preflash to main flash. This ratio and energy table can be used for...
