Friction material is a component material used in power machinery to rely on friction to perform braking and transmission functions. It mainly includes brake pads (brake pads) and clutch faces (clutch pads). Brake pads are used for braking and clutch pads are used for transmission. Due to its high requirements for safety, more attention is paid to the production process, especially its mixing process requires the use of higher performance friction material mixers to solve fiber powder mixing. problem.
Any mechanical equipment and various vehicles in motion must have brakes or transmissions. Friction materials are a key component of such brakes or transmissions. Its main function is to absorb or transfer power through friction. If the clutch disc transmits power, the brake disc absorbs kinetic energy. They enable machinery and various motor vehicles to work safely and reliably. Therefore, friction material is a widely used and even critical material, so its mixing process occupies a higher position, and an efficient mixer can achieve its high performance applications.
Friction material is a kind of polymer ternary composite material, which is a physical and chemical composite. It is composed of polymer binders (resin and rubber), reinforcing fibers and friction performance modifiers, and other compounding agents. It is a product made through a series of production and processing.
Fiber-reinforced material constitutes the main material of friction materials. It gives sufficient mechanical strength to friction products, which can withstand the load of grinding and riveting processing of friction plates in the production process and the braking and transmission generated during use. Impact force, shear force, pressure.
The fibers are generally agglomerated fibers and bundled fibers. The friction material powder mixture contains agglomerated or bundled fibers, and it is difficult to mix uniformly using an ordinary mixer. This is because ordinary mixers do not have the mechanical ability to break up these fibrous structures. Even if a forced-shear mixer is used, the fibrous structures cannot be broken down and the mixing fails.
Using a dual-motion flying knife dispersing mixer is a good way to solve the problem of mixing powder with fibrous tissue. The core of its technology is: using high-speed flying knives to break up bundles and lumps of fibers, and at the same time let the powder fill the gaps between the fibers to prevent re-adhesion between the fibers. Because the flying knife speed of the flying knife dispersing mixer can be set to 1000 rpm or even higher, the speed of the edge of the flying knife reaches 12 meters per second, so the impact force generated by the rotating speed is enough to break up the clumps of fibers or bundle Fibers, so that the dispersed fibers are evenly distributed in the main powder, so that while the fibers are dispersed, the materials are more uniformly mixed.
