Abstract

The process for the expanded polyurethane plates manufacturing, according to which the prepared polymerized reaction mixture comprising gas generator is fed to the moving angles (7, 10) of the conveyer for that into the almost hermetically sealed volume (17) takes place the free swelling and polymerization of this mixture.The pressure in this volume is kept under certain limits at the expense of gas continuous feed into the volume supplementary to the educed gas at the simultaneous gas evacuation from the value owing to which in this value can be reduced the pressure vibrations and the variation of other parameters, for example temperature, can be regulated that allows to obtain a foam plastic with constant properties.In this invention is also described the almost hermetically sealed machine for the foam plastic plates continuous manufacturing by means of which is realized the proposed process.
