  • TIRE
    Publication number: 20250001811
    Abstract: The present invention relates to a tire with noise-reducing main grooves and more particularly to a tire with noise-reducing main grooves for reducing resonance noise of the tire. The tire includes: a groove portion which is formed to extend circumferentially along a circumference of a tire tread; and a knurled portion which is formed on bottom and side surfaces of the groove portion. The knurled portion is provided to reduce noise energy by narrowing an air path formed when the groove portion and the ground contact each other.

  • Apparatus and method for preparing carbon black
    Patent number: 11591224
    Abstract: Disclosed are apparatus and method for preparing carbon black, in which the carbon black may be continuously formed and activated. In one embodiment, carbon black powders formed in a combustion reactor are converted into a slurry which in turn is refluxed to the combustion reactor in a repeated manner, thereby to allow successive activation treatments. In this way, a sufficient residence time for the activation of the carbon black may be secured.

  • Tire with reduced noise
    Patent number: 11117425
    Abstract: Disclosed is a tire configured for reducing noise during running of the tire by forming a predetermined shape in a groove of the tire to reduce a peak of air column resonance sound. The tire with reduced noise includes a first protrusion formed on a sidewall of a groove, protruding in a depth direction of the groove, and dispersing sound waves generated in a tread, and a second protrusion formed on the sidewall of the groove, protruding in a longitudinal direction of the groove, and dispersing sound waves generated in the tread.
