Abstract
Procedeul de formare a suprafetei polimerilor expandati liber într-o treapta din amestecuri de lichide caracterizat prin aceea ca în scopul usurarii realizarii pe suprProcedeu de formare a suprafetei polimerilor, conform caruia pe suprafata polimerului ce urmeaza a fi spumat se mentine perpendicular pe peretii înconjuratori cu curent fortat de substanta gazpasa, de preferinta aer. Procedeul este utilizat în industria materialelor plastice.The process for forming the surface of the free-flowing polymers in a stage of liquid mixtures characterized in that, in order to facilitate the process of the surface polymerization process, according to which on the surface of the polymer to be foamed it is kept perpendicular to the surrounding walls with current forced by the gaseous substance, preferably air. The process is used in the plastics industry.
