Rhéologie
SiliceLa silice est la forme naturelle du dioxyde de silicium (SiO2) qui entre dans la composition de nombreux minéraux.
La silice existe à l'état libre sous différentes formes cristallines ou amorphes et à l'état combiné dans les silicates, les groupes SiO2 étant alors liés à d'autres atomes (Al : Aluminium, Fe : Fer, Mg : Magnésium, Ca : Calcium, Na : Sodium, K : Potassium...).
Les silicates sont les constituants principaux du manteau et de l'écorce terrestre. La silice libre est également très abondante dans la nature, sous forme de quartz, de calcédoine et de terre de diatomée. La silice représente 60,6 % de la masse de la croûte terrestre continentale.
Solutions de polymèreIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : The article reports on the development of fumed silica particles to improved the rheology control of structural adhesives. It states that the new product is designed to rapidly self assemble in three dimension (3D) network structures when dispersed in liquid polymers with the physical and chemical qualities of epoxy resins. However, the application faces challenges in the production of composite blades for wind energy turbines.

Pressure-sensitive tapes are often designed to meet specific end-use performance criteria, so manufacturers invest considerable resources to select the proper backing for a specific application. Many advances have been made in adhesive and coating technology, but the substrate still needs to be considered when choosing a tape. The key properties of paper-based backings can impact the finished product.Note de contenu : - NO TYPICAL TAPE

Rubans adhésifsIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Nitrile-phenolic film adhesives are a compelling alternative to liquid adhesives for demanding applications.
Demanding manufacturing applications require high-quality materials—from the most prominent base materials to the most imperceptible of components—that will not slow down the production process. Nitrile-phenolic adhesives are used to bond friction materials to metallic substrates in drive components for cars, trucks, off-road vehicles and motorcycles. They can also be found in everyday manufacturing for crane brakes, pressure vessels and machinery clutches/brakes.
The choice of adhesives can make a big difference in how quickly and inexpensively a product can be produced. Thus, it is important to be aware of all of the options available—especially in industries known for strict regulations, fierce competition, demanding consumers and quickly evolving technology.
While liquid adhesives and other traditional fastening devices have been used in manufacturing for years, alternative adhesive materials such as pressure-sensitive adhesives (PSAs) have enabled some manufacturers to create safer, higher quality end products than would have been possible through other adhesion methods. Nitrile-phenolic films, specifically, are structural adhesives that have been shown to deliver quality and performance without requiring substantial manufacturing resources.Note de contenu : - WHAT IS NITRILE-PHENOLIC TAPE ?

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
