Abstract

In this paper, the kinetics of polyurethane’s foaming reaction is studied in order to be used in the chemical brake system of a CHEMICAL AUTOMOTIVE. The original aim of this project is to control the volumetric expansion of the product foam, so that it cuts off the electrical current produced by an electrochemical source and stops of the automobile at a previously decided distance. The volumetric ratio of reactants, their initial amounts and also the rate, at which they are mixed in the reactor, have been investigated as the effective parameters on the speed of foam growth at room pressure and temperature. Experiments show the rigorous effect of water amount on the rate of growth and the controllability of the foaming reaction. Increase of volumetric ratio of water from 0.5 to 1 and 2, leads to an intense decrease in the rate of foam growth. Also the Polyol to Diisocyanate ratio affects the uniform growth and the stability of the foam and therefore has an intense effect on the controllability of this reaction.
