Abstract

"SIMULADOR AMBIENTAL PARA ENVELHECIMENTO ACELERADO DE POLìMEROS". Do tipo que é destinado aos ensaios de envelhecimento acelerado de polímeros através da exposição à radiação ultravioleta, caracterizado pelo fato de compreender três compartimentos indicados pelas referências numéricas (1), (2) e (3); sendo que o compartimento (2) ficam situados o conjunto de lâmpadas (L) que formam duas bancadas (B), os suportes (S) das amostras (C) e o reservatório de água (R), usado nos ciclos de condensação que simulam condições de precipitações pluviométricas; no compartimento (2) são previstas duas estruturas em forma de trapézio (4) cada uma das quais sendo uma armação onde são fixadas as braçadeiras (5) que suportam as lâmpadas (L); devido a simetria do equipamento existem, no compartimento (2), duas janelas (6), uma em cada lateral, cujas dobradiças na região superior permitem a abertura no sentido ascendente."ENVIRONMENTAL SIMULATOR FOR ACCELERATED POLYMER AGING". Of a kind intended for accelerated polymer aging testing by exposure to ultraviolet radiation, characterized in that it comprises three compartments indicated by the numerical references (1), (2) and (3); where the compartment (2) is located the set of lamps (L) that form two benches (B), the sample holders (S) and the water reservoir (R) used in the condensation cycles simulating rainfall conditions; in the housing (2) there are provided two trapezoidal structures (4) each of which is a frame to which are attached the clamps (5) supporting the lamps (L); Due to the symmetry of the equipment, there are two windows (6) in the compartment (2), one on each side, whose hinges in the upper region allow the opening upwards.
