This paper introduce a way to prepare Guizhou palygorskite mineral nanoparticles by
dry-wet ball milling and modified its surface, with adding it in pre-polymer and dispersing with
supersonic disperser. Then it introduced preparing the tung oil phenolic-formaldehyde (TPF)/
nano-palygorskite composite resin by situ. The TENSOR27 IR and JEM-2000FX II test shown that
the nano-palygorskite particles embedded in the polymer and they were more evenly dispersed. By
NETZSCHSTA409 thermal analyzer for TG analysis, the elevated of compound PF has been
enhanced.
The in situ mechanochemical auto-restoration technology of tribosurfaces has become a subject of great interest in recent years. This paper reports a study of the effect of Ag content in palygorskite (P)/Ag nanocomposites on friction-reducing and antiwear properties of 45 mild steel tribopair. The electron microprobe has been used in its surfaces topography and elemental analysis. The study shows the auto-restoration layers formed on the tribopairs can decrease the wear mass loss and friction coefficient of these samples remarkably; when the Ag content in P/Ag was properly increased, it can help to decrease the friction coefficient of the tribopair samples.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
