Purpose. To simplify the manufacturing process of plastic parts reinforced with carbon particles.
Technical properties.
Granule size – 3-3.5 mm, reinforcing particle size – 200 – 500 µm.
Mixing time – 10-30 min depending on the volume of components.
The maximum percentage of the reinforcing component is 22-35% depending on the size of the granules and the size of the reinforcing component particles.
Sector of application. Low-pressure casting. Enterprises using technologies with composite materials.
Advantages. Reduction of waste during the use of the technology. Possibility of using uncleaned reinforcing components.
Technical and economic effect. Reduction in cost and simplification of the manufacturing process of plastic parts with a reinforcing component while simultaneously recycling the mechanical processing of composite material waste.
Description. The problem of waste recycling during the mechanical processing of composite materials. The technology allows recycling waste without using intermediate stages of raw material preparation. In addition, the technology is not demanding on the purity of the input components, i.e. the reinforcing component does not necessarily have to be cleared of the binding components that were used in the production of the original material. The absence of intermediate stages of preparation of composite raw materials for casting, ease of integration into production cycles and ease of control of the amount of the reinforcing component. Dust particles formed during the production of parts from composite materials (their mechanical processing) are mixed with a binding component (usually water) to form a suspension. After that, the output plastic granules are thoroughly mixed in the mixer and the reinforcing component particles settle on the surface. Subsequently, the granules are unloaded and dried. The reinforcing particles are held on the surface of the granules due to Van der Waals forces. After that, the particles are loaded into the hopper of the casting machine and the process of casting plastic into the mold takes place.
