Par exemple, la modification de la surface du carbonate de calcium affecte les composites de caoutchouc. Cela affecte leurs performances. De plus, le carbonate de calcium lourd et le N550 renforcent le caoutchouc chloropr\u00e8ne lorsqu&#039;ils sont ajout\u00e9s. Le caoutchouc utilisait du carbonate de calcium lourd de 800 mesh, 2 800 mesh et 4 000 mesh. Il a \u00e9t\u00e9 compar\u00e9 au carbonate de calcium l\u00e9ger. Les r\u00e9sultats ont montr\u00e9 que\u00a0:<\/p>\n\n\n\n<p>Le caoutchouc rempli de carbonate de calcium lourd a une contrainte de traction plus \u00e9lev\u00e9e et une viscosit\u00e9 Mooney plus faible. Ceci est compar\u00e9 au caoutchouc rempli de carbonate de calcium l\u00e9ger. Cela am\u00e9liore le traitement. De plus, le temps de grillage est l\u00e9g\u00e8rement plus court. Mais il r\u00e9pond toujours aux exigences de production.<\/p>\n\n\n\n<p>\u00c0 mesure que la taille des mailles du carbonate de calcium lourd augmente, la viscosit\u00e9 Mooney augmente. Il en sera de m\u00eame pour le temps de grillage et la r\u00e9sistance \u00e0 la traction. Il en sera de m\u00eame pour la r\u00e9sistance \u00e0 la d\u00e9chirure et \u00e0 la rupture du compos\u00e9 de caoutchouc. Cette augmentation am\u00e9liorera la s\u00e9curit\u00e9 des proc\u00e9d\u00e9s et les propri\u00e9t\u00e9s m\u00e9caniques. Cependant, le coefficient de vieillissement peut \u00eatre l\u00e9g\u00e8rement inf\u00e9rieur. Cela r\u00e9duirait la r\u00e9sistance au vieillissement.<\/p>\n\n\n\n<p>Le caoutchouc rempli de carbonate de calcium lourd est plus lisse. Il est \u00e9galement plus r\u00e9sistant au vieillissement et \u00e0 l\u2019air. Ils sont meilleurs que ceux en caoutchouc l\u00e9ger charg\u00e9 de carbonate de calcium. Ils ressemblent \u00e0 ceux des m\u00e9langes de caoutchouc remplis de carbonate de calcium l\u00e9ger. Ils ont les m\u00eames propri\u00e9t\u00e9s m\u00e9caniques, de flexion et de perte par hyst\u00e9r\u00e9sis. Mais l\u2019ajout de carbonate de calcium lourd aux couches de caoutchouc \u00e9tanches \u00e0 l\u2019air peut encore grandement les am\u00e9liorer. Ces avantages du carbonate de calcium lourd le rendent largement utilis\u00e9. Il est utilis\u00e9 dans les compos\u00e9s de caoutchouc en couche herm\u00e9tique. Les m\u00e9langes de caoutchouc \u00e9tanches \u00e0 l&#039;air sont principalement utilis\u00e9s dans le b\u00e2timent et l&#039;a\u00e9rospatiale. Ils stoppent les fuites de gaz, de vapeur d\u2019eau ou de liquide. Sa qualit\u00e9 affecte directement les performances de s\u00e9curit\u00e9 du projet. Ainsi, le carbonate de calcium lourd est une charge inorganique de haute qualit\u00e9. Il peut am\u00e9liorer les performances du caoutchouc herm\u00e9tique. Cela r\u00e9duit \u00e9galement les co\u00fbts et aide les industries connexes.<\/p>","protected":false},"excerpt":{"rendered":"<p>D\u00e9sormais, le caoutchouc herm\u00e9tique du pneu utilise principalement du carbonate de calcium l\u00e9ger pour le gonfler.
