Description
Известен способ получени пенопластов вспениванием исходного продукта в шнековом устройстве.A known method for producing foams by foaming the starting product in a screw device.
С целью получени готового продукта заданного гранулометрического состава процесс вспенивани предлагаетс вести путем подачи подлежащих вспениванию гранул пенопласта в тороид, где они вращаютс в потоке гор чего воздуха, нагнетаемого вентил тором . Достигнув определенного удельного веса, гранулы автоматически вылетают из тороида.In order to obtain a finished product of a given particle size distribution, the foaming process is proposed to be carried out by feeding foam granules to be foamed into the toroid, where they rotate in a stream of hot air blown by a fan. Having reached a certain specific weight, the granules automatically fly out of the toroid.
Предмет изобретени Subject invention
Способ получени пенопластов путем вспенивани с последуюгцей классификацией, отличающийс тем, что, с целью улучшени качества готового продукта, процесс вспенивани ведут путем подачи подлежащего вспениванию материала в тороид с последующей выгрузкой готового продукта заданного гранулометрического состава.The method of producing foams by foaming followed by classification, characterized in that, in order to improve the quality of the finished product, the foaming process is carried out by feeding the material to be foamed into the toroid with subsequent unloading of the finished product of a given particle size distribution.
