Abstract

The paper presents physicochemical investigations of the structure and properties of a nano-modifier synthesized from peat, the local raw material subjected to pyrolysis in air-free conditions. This nano-modifying additive is a combination of various forms of nanocarbon and polar and non-polar adsorbing materials such as silica (SiO2), calcium carbonate (CaCO3) and carbon (C). Different nanocarbon forms (nanotubes, fullerenes, nanodiamonds, nanofiber, nanodispersed carbon) used in different proportions with micro and macro peat components give multifunctional properties to the synthesized nano-modifier and the ability to positively change tribological properties of hydraulic fluids and oil lubricants. Test results of type TMT-600 show that its different percentage is required to modify tribological properties of the steel tribocouple under different loading conditions. At 0.5 wt.% content of this nano-modifier, stabilization of the friction ratio and an increase of seizure load are observed.

Highlights

Nanomodifiers are being widely used in different fields of science, technology, and production [1,2,3,4,5,6]
The modifiers obtained due to the thermal treatment are divided into four types depending on the treatment temperature
Materials and methods The synthesized ТМТ-600 additive is used in construction industry to control the properties of cement systems

Summary

Introduction

Nanomodifiers are being widely used in different fields of science, technology, and production [1,2,3,4,5,6]. Today the nanomodifier synthesis methods are the relevant and important and significant problem of practical and theoretical interest, which should satisfy the criteria for technological availability and efficiency, energy and resource saving, ecological safety, natural balance, biocompatibility, and economic feasibility[7,8,9]. In-situ resources of the Siberian region allow the researchers to develop peat-based modifiers for the property control of dry mix mortars and other composite materials. The stock of this partially renewable resource available in Tomsk region achieves 29.3 billion tons per year per 40% humidity. The modifiers obtained due to the thermal treatment are divided into four types depending on the treatment temperature.
