ServomécanismesIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Adhesive dispensing systems can be difficult to specify when buying new machines and hard to understand when trying to improve existing performance. Two items critical to dispensing performance and resulting product quality are the metering principle and motor drive selection. The metering principle defines the adhesive delivery process, while the motor drive determines the fluid control method for adhesive delivery. This article explains the purpose of servo motor drives used in dispensing adhesives and sealants.

PolyuréthanesIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Two-part polyurethane elastomer materials, such as polyols and isocyanates, continue to grow in formula variations and are expanding their use with product manufacturers due to their improved performance over other materials. One current example of formula growth is the development by many chemical manufacturers of green, eco-friendly, bio-based, sustainable polyurethanes as an alternative to petrochemical-based products. In many cases, these new formulations affect the design of meter/mix/dispensing equipment.
When compared to epoxies, silicones, polyesters and methacrylates, reactive cure polyurethanes for low-pressure dispensing have unique characteristics, such as faster cure, change ratio to adjust durometer, and increased resistance to external issues and influences. Reactive cure polyurethanes are sometimes used to replace one-part, heat-cure polyvinyl chloride (PVC), two-part epoxies, two-part silicones, two-part polyesters and other materials. One example is two-part, fast-cure polyurethane replacing heat-cure PVC in the filter industry for durometer control, increased resistance to chemicals and high-speed manufacturing.
Two-part polyurethane elastomers have characteristics that usually cause meter/mix/dispensing systems to differ from dispensing systems for other materials. The two-part polyurethane equipment usually needs to include different supply units, temperature control, degassing equipment, air dryers and unique mixers. In addition, the use of reactive polyurethane typically requires precision dispensing systems. Tight ratio tolerances and precise dispense volumes are often more important with fast-cure urethane and high-speed automation applications.Note de contenu : - Reactive metering technology
