  • SIZING AGENT COMPOSITION, SIZING AGENT, CARBON FIBER COVERED WITH SIZING AGENT, AND COMPOSITE MATERIAL
    Publication number: 20250034363
    Abstract: The present invention relates to a sizing agent composition, a sizing agent, a carbon fiber covered with the sizing agent, and a composite material. The sizing agent composition includes a polyamic acid and an alkali agent. The alkali agent has a specific molecular weight, and there is a specific molar ratio between the polyamic acid and the alkali agent, such that emulsification stability of the polyamic acid and thermal stability of a sizing layer consisting of the sizing agent are enhanced, thereby increasing interlayer bonding strength in the composite material that is made by the carbon fiber covered with the sizing agent.

  • Rubber pellet treatment
    Patent number: 11472930
    Abstract: Rubber pellets are coated with an anti-tack material. The anti-tack material may be comprised of a metallic stearate, such as magnesium stearate. The coated rubber pellets are loaded on to a rotational conveyance mechanism that rotates at a speed and radial amount to provide an interaction time between the rubber pellets and the anti-tack material. The coated rubber pellets may then be dried in a centrifuge dryer having a plurality of angled fins extending from a rotational shaft.
