Title
(EN) NOISE ABSORBING COMPOSITE FOR THE SUSPENSION SYSTEM OF COMPRESSORS, MOTORS AND SIMILAR APPARATUS
(FR) MATERIAU COMPOSITE AMORTISSEUR DE BRUIT POUR LE SYSTEME DE SUSPENSION DE COMPRESSEURS, MOTEURS ET APPAREILS SIMILAIRES
Abstract
(EN)
Noise absorbing composite for the suspension system of compressors, motors and similar apparatus, which can be used in a suspension system of the type defined by metallic helical springs (3A, 3B), which interconnect a fixed case (2) of a hermetic compressor with its motor-pump assembly (1), the latter being provided with a high frequency vibratory movement, said noise absorbing composite (10) being defined by a portion of viscoelastic material, disposed in close and permanent contact with a substantial portion of the surface of said springs (3A, 3B), said viscoelastic material (10) comprising: a main elastomeric portion, defined by 100 parts of a compound, which is selected from the group consisting of: polysiloxanes, tetracyclosiloxanes, pentacyclosiloxanes or mixtures thereof; a portion of vulcanization, defined from 0.2 to 6.0 phr of a compound selected from the group consisting of: di-cumile peroxide; 2.5-bis (ter-butyl) peroxide; 2.5 dimethylhexane, or mixtures thereof.
(FR)
Un matériau composite amortisseur de bruit pour le système de suspension de compresseurs, moteurs et appareils similaires peut être utilisé dans un système de suspension du type défini par des ressorts métalliques hélicoïdaux (3A, 3B) qui connectent un carter fixe (2) d'un compresseur hermétique à l'agrégat (1) de moteur et de pompe qui génère un mouvement vibratoire de haute fréquence. Ce matériau composite (10) amortisseur de bruit comprend une partie en un matériau viscoélastique en contact étroit et permanent avec une partie considérable de la surface desdits ressorts (3A, 3B). Ce matériau viscoélastique (10) contient une partie principale élastomère définie par 100 parts d'un composé sélectionné dans le groupe constitué des polysiloxanes, des tétracyclosiloxanes, des pentacyclosiloxanes ou de mélanges de ceux-ci; une partie vulcanisée définie par 0,2 à 6,0 phr d'un composé sélectionné dans le groupe constitué du peroxyde di-cumile, du peroxyde 2,5-bis (ter-butyle), du 2,5 diméthylhéxane, ou de mélanges de ceux-ci.
