Blending Systems
Blending systems allow in-house formulation of liquid or liquid and solid particle blends to achieve the specific characteristics of an end product. Polyols typically require the addition of blowing agents, activators, emulsifiers, foam stabilizers, flame retardants or other auxiliary materials to achieve those characteristics.
Metering systems
Based on the specific requirements in terms of accuracy, metering speed, and batch size, dosing is carried out either via a gear flow meter, a mass flow meter, or load cells (with pre-weighing of small quantities if necessary).
Inline dosing
For a continuous mixing the process can also be represented as inline dosing. For this purpose, the main component and additional components are fed into a static or dynamic mixing system in a controlled manner. Through permanent control of the material flows, the mixture is available with the specified recipe and quality after leaving the mixing unit.
Blending systems for liquids and powders
Blending systems precisely meter and blend various additive into the main polyol stream to improve both mixing ability and reaction behaviour. Hennecke offers proven equipment for conditioning, blending and mixing raw materials with the polyol stream, including static or dynamic mixers and integrated gas loading units.
