Lubricants impact improvers

Lubricants. Lubricants represent a broad class of materials that are used to improve the flow characteristics of plastics during processing. Besides this primary task of improving flow properties, lubricants can act as melt promoters, antiblock, antitack, and antistatic agents as well as color and impact improvers. They can be used in conjunction with metal release agents and heat stabilizers. Lubricants are widely...

Note that this DVW pipe formulation contains no impact modifier or other lubricants. Depending upon the desired finished properties of the pipe, the minimum impact strength standards may be achieved simply by increasing the wall thickness of the pipe specimen. Other lubricants may improve processing and fusion speed but may add cost. 

Improved sensors allow computer monitoring of the system for safety and protection of the equipment from damage. Sensors include lubrication-flow monitors and alarms, bearing-temperature sensors, belt scales, rotation sensors, and proximity sensors to detect ore level under the crusher. The latter prevent jamming of the output with too high an ore level, and protect the conveyor from impact of lumps with too low an ore level. Motion detectors assure that the conveyor is moving. Control applied to crusher systems including conveyors can facilitate use of mobile crushers in quarries and mines, since these can be controlled remotely by computer with reduced labor. 

The properties of immiscible polymers blends are strongly dependent on the morphology of the blend, with optimal mechanical properties only being obtained at a critical particle size for the dispersed phase. As the size of the dispersed phase is directly proportional to the interfacial tension between the components of the blend, there is much interest in interfacial tension modification. Copolymers, either preformed or formed in situ, can localize at the interface and effectively modify the interfacial tension of polymer blends. The incorporation of PDMS phases is desirable as a method to improve properties such as impact resistance, toughness, tensile strength, elongation at break, thermal stability and lubrication. 

Additives interact in a variety of ways, both in the bulk oil and on surfaces. Knowing the nature of additive interactions and their impacts on performance can help in oil formulations and improve lubricated systems. Additive interactions in the bulk phase have been particularly useful in understanding synergism and antagonism between different classes of additives. Many of these interactions affect processes on surfaces.

Various surface treatments are now in use for improving surface lubricity, reducing damage by impact, or giving additional decorative effects. 

A broad area of application of plasticizing action of the medium is the use of surface active substances in the treatment of metals by pressure (dragging, rolling, impact extrusion). Plastification of surface layers of the treated metal due to the surface active components incorporated into greases and lubricants significantly reduces loads that one needs to apply in order to carry out these processes. It also improves the quality of the surface and decreases the level of internal stresses in the near-surface layers of a metal...
