The evolution of the film thickness in a grease lubricated rolling bearings is given by continuous process loss and replenishment oil track. It believed that long run, maintained bleeding from reservoirs. capabilities thus have an impact on and/or bearing life. ability to bleed changes during operation due mechanical ageing, which affects fiber structure grease. In this study lubricating consid...

The significant effect of the addition very small proportions nanofibres and nano-particulates on physical mechanical properties solid materials has been long observed described. electrospun fibres liquid not so widely examined. In this paper, polyvinyl alcohol (PVOH), zein nanofibers in sunflower (Helianthus annuus) oil its viscosity was quantified. For a given amount material, trend increasin...

Porous ceramics have attracted researchers due to their high chemical and thermal stability. Among various types of porous ceramics, reticulated both porosity good permeability. These properties are difficult replace with metals polymers. ZTA is used in a variety applications, wealth experimental data has already been collected. However, research reports on zirconia-toughened alumina (ZTA) insu...

Cocoa liquor, butter, and powder represent derived products from a small portion of the fruits, compared with cocoa pod husk (CPH) which accounts for ∼ 70 % fresh weight. CPH, improperly disposed in plantations, can cause diseases threatening worldwide chocolate production. However, this biomass be potential source bioactive compounds aligned circular economy. An overview on different methods e...

Higher concentration is beneficial for the Paste and Thickened Tailings (PTT) operation in metal mine. Partial paste thickeners are produced lower density underflow. Flocculated tailings intended to form a water entrapped network structure thickener, which detrimental underflow concentration. In this study, continuous thickening experiment was carried out ultra-fine tungsten study influence of ...

The application of aloe vera in textile processing is gaining worldwide detection as one the hopeful approaches to pollution issues and cost reduction. Aloe gel possesses some biological activities unique properties such colorless, transparent, viscosity which meet using a printing thickener, mordant, antimicrobial for different fabrics dyes. used pre-treatment scouring, desizing, softening, du...

Mechanical degradation by shear is one of the mechanisms that limits life-time lubricating grease in a rolling bearing. It results change micro-structure thickener–oil system, leading to bleed and consistency. The resistance can be quantified using worker. In this article, novel approach described, where worker used measure rheological properties situ, while aging grease. energy pressure losses...

This work studies the performance of three phosphonium-based ionic liquids ([P6,6,6,14][BEHP], [P6,6,6,14][TCM] and [P6,6,6,14][DEC]) when used separately as additives on thermal conductivity, stability tribological properties two non-additised greases (a lithium-based a calcium-based grease). The main results confirmed that improved both greases. Only mixtures G1 + 5%[P6,6,6,14][BEHP] G2 5%[P6...
