L'aramide est un tissu naturel ignifuge qui a montr\u00e9 de vastes perspectives d'application dans de nombreux domaines en raison de ses propri\u00e9t\u00e9s physiques et chimiques uniques. \u00c9galement connue sous le nom de fibre polyamide aromatique, il s'agit d'une fibre synth\u00e9tique haute performance fabriqu\u00e9e par filage de r\u00e9sines sp\u00e9ciales. Sa structure mol\u00e9culaire est unique, compos\u00e9e de longues cha\u00eenes alternativement reli\u00e9es par des liaisons amides et des anneaux aromatiques. En fonction des diff\u00e9rences de structure mol\u00e9culaire, l'aramide est principalement divis\u00e9e en m\u00e9ta aramide (aramide I, 1313), para aramide (aramide II, 1414) et aramide h\u00e9t\u00e9rocyclique (aramide III) dans l'industrie. Quelles sont donc les utilisations et les caract\u00e9ristiques de l'aramide ?<\/p>\n

\"Aramide\"<\/p>\n

L'utilisation de l'aramide :<\/strong><\/p>\n

1. Long filament
\n2. P\u00e2te \u00e0 fibres courtes
\n3. Papier
\n4. Tissus et mat\u00e9riaux composites
\n5. L'a\u00e9rospatiale
\n6. Militaire
\n7. Le transport
\n8. Communication
\n9. Pneu<\/p>\n

Types d'aramide :<\/strong><\/p>\n

1. Aramide voisin
\n2. Para aramide (PPTA)
\n3. M\u00e9ta aramide (PMTA)<\/p>\n

Avantages de l'aramide :<\/strong><\/p>\n

Il pr\u00e9sente d'excellentes performances, notamment une r\u00e9sistance \u00e9lev\u00e9e, un module \u00e9lev\u00e9, une r\u00e9sistance aux acides et aux bases \u00e0 haute temp\u00e9rature, une l\u00e9g\u00e8ret\u00e9, une isolation, un antivieillissement, une structure chimique stable, une combustion s\u00fbre et une longue dur\u00e9e de vie.<\/p>\n

Inconv\u00e9nients de l'aramide :<\/strong><\/p>\n

Faible r\u00e9sistance \u00e0 la lumi\u00e8re et aux ultraviolets, pas de r\u00e9sistance aux acides forts et aux alcalis, faible r\u00e9sistance \u00e0 la compression et faible module, faible force d'adh\u00e9rence entre les fibres et l'interface de la r\u00e9sine, faible absorption de l'humidit\u00e9 et hydrolyse facile.<\/p>","protected":false},"excerpt":{"rendered":"
