Abstract

Purpose

This paper aims to explore the leaf-surface wax as green lubricant additive and compare the tribological properties between coastal and inland leaf-surface waxes of the same species plant.

Design/methodology/approach

The leaf-surface waxes were extracted from the leaves of Robinia pseudoacacia cv. Idaho and Populus nigra in coastal and inland areas, and then the compositions of the four kinds of leaf-surface waxes were characterized using a gas chromatography–mass spectrometry. The tribological properties of these leaf-surface waxes as lubricant additives in the base oil of synthetic ester (SE) were investigated by an MFT-R4000 reciprocating friction and wear tester. As well as the surface morphologies and chemical compositions of the wear scars were characterized by a scanning electron microscope and time-of-flight secondary ion mass spectrometry, respectively.

Findings

The results indicate that all the leaf-surface waxes as additives can effectively improve the friction reduction and anti-wear performances of SE for steel–aluminum friction pairs. Therein, coastal leaf-surface waxes have better tribological performances than inland leaf-surface waxes, which are attributed to that the leaf-surface waxes extracted from coastal plants can form a better protective film on the worn surface throughout the friction process.

Originality/value

This paper investigated a new kind of environmentally friendly lubricant additive and compared the tribological properties of the leaf-surface wax extracted from coastal and inland plants. The associated conclusions can provide a reference to explore the tribological performances of leaf-surface wax as green lubricant additive.

Abstract

Oleochemicals can be made from the components of renewable animal, marine and vegetable oils and fats. This oleochemical group of products is a large one, comprising fatty acids, glycerol and numerous derivatives of these including fatty alcohols, fatty esters, and nitrogen‐, phosphorus‐and sulphur‐containing materials. Polyoxyalkylated end products from the above, from heavy metal and water‐soluble soaps, epoxidised chemicals, polymer components, and the quarternary ammonium compounds are found. The oleochemicals of interest to the lubricants manufacturer are those which function in some specific manner. Anti‐corrosive, anti‐oxidant, anti‐squawk, anti‐stick, anti‐sludge, anti‐wear detergent, dispersant and oiliness agents, pour point depressants and viscosity modifying materials, are examples.

Abstract

Purpose

The aim of the present paper to compare the cleaning treatments of paper samples exposed to artificial aging, toluene and isopropyl alcohol gel in cleaning wax stains.

Design/methodology/approach

In total, paper samples were made from wood pulp. They had a deterioration phenomenon represented in the stains of the paraffin wax, so two types of cleaning were used: A traditional method using a toluene solution and another new method using isopropanol gel by a cotton swap in a circular movement until the completion of the cleaning process. Then, all paper samples were treated with toluene and isopropanol to handle the second artificial aging and detect how the samples were affected by artificial aging. For identifying the efficacy of these materials in removing paraffin wax stains, a range of examinations and analyses were used, such as universal serial bus, scanning electron microscope, infrared analysis (IR), pH analysis, color change analysis. Moreover, these results were compared with the standard sample’s results.

Findings

The results of examinations and analyses proved that the use of toluene affected the paper samples. Their effects were twice as weak, fragile and degraded paper fibers compared to isopropanol gel. Therefore, the isopropanol gel is preferred for paper cleaning to the toluene solution.

Originality/value

This paper highlights the efficiency of isopropyl alcohol gel in cleaning wax stains from historical paper supports.

Abstract

Focuses on oleochemicals, a natural alternative to mineral oils for use in liquid lubricants, metal working coolants, quenchants and hydraulic fluids. Natural oil based products generally have many advantages over mineral oils, including lower volatility, better inherent lubricity, higher viscosity index, higher bulk modulus, better fire resistance and better solvency. Details the manufacturing process.

Abstract

The science of lubrication has developed slowly from the earliest use of oils and fats of animal or plant origin, such as tallow and castor oil, to the modern design of lubricants for a specific purpose. The slow evolution of scientific lubrication has been due in part to the complicated nature of lubrication and lubricants, and also to the need to concentrate on the development of lubricants to satisfy the requirements of new and improved mechanisms. Research into the nature of lubrication and the relation between composition and properties of lubricants has been limited by the production demands for more and better lubricants.

Abstract

Purpose

Fruits and vegetables, being good source of energy, health promoting and protecting compounds with unique taste and flavor, are attracting consumers since ages. These horticultural produces start deterioration just after harvest; therefore, their proper storage is must during transportation and storage to retain maximum quality parameters and for good market value. Best storage conditions are required to prevent growth of micro flora and to maintain the nutritional values of harvested produce. Retailers and processors in every corner of world want to move toward the cheaper ways to increase the shelf life and texture of horticultural crops for better consumer preference. The purpose of this paper is to make consumers and researchers aware about different post harvest malpractices in fresh fruits and vegetables.

Design/methodology/approach

Lot of chemicals like colors, artificial ripening agents, sweeteners and waxes are applied on surface of horticulture produce to siphon off money from consumers, and these have adverse health effects directly or indirectly. Various regulatory agencies have launched various programs, acts and laws for monitoring and avoiding such unhealthy ways. Regulatory bodies launched training programs also for the food handlers and consumers to ensure the food safety from farm to fork.

Findings

This paper will throw light on different malpractices followed by retailers to manipulate the quality which causes adverse health effects and to create consumer awareness regarding such malpractices.

Originality/value

The paper emphasizes on current malpractices followed by retailers to mislead the consumers about fruits’ and vegetable’ quality by using sweeteners, colors and other chemical. On prolonged consumption, such substances lead to major health issues such as attention disorder.

Abstract

A corrosion inhibitor may be defined as a material which, when added in small amounts to a corrosive product or environment affecting a metal, effectively decreases its corrosion rate or perhaps prevents it altogether.
