Air chaud<\/h1>\n

Une machine \u00e0 air chaud produit de l\u2019air chaud avec une temp\u00e9rature pr\u00e9cise et contr\u00f4l\u00e9e afin de chauffer directement la bande adh\u00e9sive. La bande et le tissu sont introduits entre deux rouleaux \u00e0 mouvement inverse et sous pression . La vitesse lin\u00e9aire des rouleaux est la vitesse de soudage.  <\/p>\n

Quand une bande adh\u00e9sive est chauff\u00e9e, l’adh\u00e9sif sur la bande est activ\u00e9. La bande activ\u00e9e est appos\u00e9e sous pression sur une couture de tissu enduit ou stratifi\u00e9. Une fois refroidi, la bande et la couture sont solidement attach\u00e9es. L\u2019adh\u00e9sion est telle que de l\u2019eau sous pression ne pourra s\u2019infiltrer entre la bande et la couture. Vous obtenez ainsi une couture \u00e9tanche. <\/p>\n

Pendant le soudage, de l’air chaud souffle de la buse. L’air chaud qui atteint la surface de la bande est en fait un m\u00e9lange d\u2019air chaud sortant de la buse et de l\u2019air environnant, par cons\u00e9quent, la temp\u00e9rature r\u00e9elle sur la bande est inf\u00e9rieure \u00e0 la temp\u00e9rature de la buse. Plus la distance entre la buse et la bande est grande, plus le pourcentage de l’air environnant est important. Par contre, un d\u00e9bit d’air chaud plus \u00e9lev\u00e9 r\u00e9duira le pourcentage de l’air environnant augmentant ainsi la temp\u00e9rature sur la bande. La position de la buse bec et le d\u00e9bit d’air chaud sont donc des facteurs clefs.  <\/p>\n

Facteurs clefs pour \u00e9tancher une couture :<\/p>\n

– Temp\u00e9rature de l’air chaud
– Vitesse de soudage
– D\u00e9bit d\u2019air chaud de la buse
– Pression d\u2019air de la buse
– Position de la buse<\/p>\n

Quand un produit coh\u00e9rent est exig\u00e9, la combinaison de tous les facteurs clefs ci-dessus doit \u00eatre pr\u00e9cise et correcte. <\/p>\n
