Abstract

EN LA FABRICACION DE ESPUMAS SINTETICAS Y TAMBIEN ESPECIALMENTE EN LA DE LOS MATERIALES DE MADERA UTILIZANDO LIGADORES DE CONDENSADO DE FORMALDEHIDO Y UREA, LA RAZON MOLAR ENTRE EL FORMALDEHIDO Y UREA ES DECISIVA PARA LA RIGIDEZ RESULTANTE FINAL Y LA PRESENCIA DE UN FORMALDEHIDO GASEOSO LIBRE. PARA REDUCIR, CON UNA RAZON MOLAR FAVORABLE, LA CANTIDAD DE FORMALDEHIDO GASEOSO QUE PERMANECE EN EL MATERIAL DE MADERA Y AL MISMO TIEMPO PARA OBTENER UNA INCOMBUSTIBILIDAD EFICAZ EN LAS ESPUMAS SINTETICAS Y LOS MATERIALES DE MADERA FIJADOS DE FORMA ADHERENTE CON ISOCIANATO, LA INVENCION PROPONE EL ADHERIR UNA COMBINACION DE SUSTANCIAS EFICACES A LOS MATERIALES VIRGENES INICIALES COMO UN GRANULADO CON UN TAMAÑO DE GRANO DE 80 A 1.500 MY.
