APPLICATION OF ABRASION RESISTANT EPOXY COMPOSITIONS REINFORCED WITH DISPERSED PARTICLES OF NATURAL SANDS FOR PARTS RECOVERY (BLADES AND CULTIVATOR FEET FOR PLANTING SEEDS)
Developed clearyly self-hardening of dispersion-hardened abrasion resistant material of the following composition: component self-hardening adhesive based on epoxy resin ED-20 and the polyamine - 40 parts; dispersionhardening abrasion resistant component, quartz sand - 60 parts. Using this composite created technologies of restoration of parts with complex spatial geometry (piles and hollow rack of hoes). Technological processes are realized by forming a coating on worn through wiping local sites with the filling of cavities hard-core wear and tear on pre-laid reinforcing mesh by applying the developed composite. The method allows to form an abrasion resistant coating with regard to the curvature of the surface, copying the profile and increase its quality indicators and braking flow through the wiping of the composite in the liquid phase is achieved by attaching a reinforcing mesh with a cell size of not more than 3mm. the Application of a new composite for the restoration of dumps and hoes does not require expensive and scarce components and can be extended to other parts of complex geometrical form. Developed abrasion resistant composite and the offered technologies allow the substitution.
