Analysis of thermal processes during mechanoactivation of MoS2 and MWCNTS

Abstract

The development of the modern transport industry makes increased demands on the reliability and efficiency of road transport equipment, as well as tightening environmental standards. This applies not only to improving the elements of the internal combustion engine (ICE), transmission and suspension, but also to improving the properties of fuel and engine oil. For the mechanical activation of MWCNT and MoS2, the vortex layer apparatus ABC-150 was used - the mechanical action of which is carried out due to the movement of grinding bodies (cylindrical) in an alternating electromagnetic field, as well as the Pulverisette 5 planetary mill (spherical bodies). The studies carried out show that mechanical activation causes heating of dispersed MWCNTs and MoS2, which, when dispersing in a liquid flow, requires limiting this process precisely by the temperature parameter. At the same time, it should be noted the possibility of simultaneous mechanical activation and distribution of MCNT and MoS2 in fuel or engine oil, which ensures high processability of the process and reduces costs associated with the need to use additional equipment. Mechanical activation in a planetary mill is accompanied by a higher uniformity of the temperature field, but at the same time in ABC the process of mechanical activation is more intense and requires less time.The presented technology of mechanical activation can be used to increase the efficiency of distribution of MCNTs and MoS2, both in fuel and in engine oil. Temperature control can be carried out by varying both the mechanical activation time and the number and type of grinding bodies
