In the construction industry, for example, epoxies are used to anchor rebar and threaded rod, as well as for structural concrete repair and crack injection, while polyurethane foams are frequently used for insulation and soundproofing. In the automotive industry, polyurethanes are used to assemble filters, exterior lighting, motor covers, tail lamp lenses and other components.
Regardless of the application, a proper mix of materials is critical to the success of any two-component dispensing process. In most instances, as long as the pumping system is capable of delivering both components to the valve in the correct ratio at the desired flow rate, and an appropriate static mixing nozzle is used, the materials will be thoroughly mixed.
A common system configuration for large-scale, two-component dispensing applications consists of separate reservoirs for the base and catalyst, a pump, a meter/mix valve, and a mixing nozzle. Gear pumps or piston pumps are typically used to transport the two components from the base and catalyst reservoirs to the corresponding inlets on the meter/mix valve. When the valve is actuated, the base material and catalyst are pushed through the manifold of the valve, out to the static mixing nozzle and onto the substrate.Note de contenu : - Incorporated fillers
