Grease 101 PART 2: Grease Lubricant Oils and Thickeners

In the previous article, we gave a general description of grease lubricants, including its base penetrability and how it is measured, classification according to NLGI grade, grease drop-point, dmN factor, and more. We also mentioned that grease has three components: lubricants, thickeners, and additives. In this article, we will be going through the first two components of grease lubricant and the different factors to consider within each component.  Also read: Grease 101 PART 1: Understanding the Basics of Grease LubricantTypes

how to read concentration ratios

How to Read the Concentration Ratio

This comprehensive overview delves into the intricate realm of reading concentration ratio, presenting a clear understanding of weight/weight (w/w) and weight/volume (w/v) units. By offering an analogy that juxtaposes the additive nature of mass with the nuanced behavior of liquids, it illuminates how combining equal volumes of liquids may yield unexpected results due to density disparities. The discourse delves into concentration units—percentages, parts per million (ppm), and parts per billion (ppb)—their conversions, and the pragmatic selection of the appropriate unit

hepatitis e prevalance, transmission, and prevention strategies

Hepatitis E Virus (HEV): Prevalence, Transmission, and Prevention Strategies

Hepatitis E virus (HEV) is the leading cause of enteric viral hepatitis worldwide. Recently, autochthonous HEV infection has emerged as a significant concern in Europe, as the EFSA reported, making it a global public health issue. Despite its low prevalence overall, HEV varies significantly in different regions, with higher rates observed in developing countries. In Spain, the general population’s prevalence of anti-HEV antibodies is reported to be 1.1% (Echevarría et al., 2014). HEV is a small, spherical virus, approximately 27-34

The Science of Stain Removal: Alkaline vs Acidic Cleaners

Stain removal has always been a paramount challenge in maintaining pristine surfaces, leading to the development of specialised cleaning agents. Alkaline solutions have emerged as a powerful tool against oil-based stains, leveraging the science of saponification to emulsify and dissolve oils effectively. Conversely, mineral stains demand the acidic touch, as these solutions excel at breaking down stubborn mineral deposits. In this concise article, we uncover the chemical underpinnings of these cleaning practices and explain the reasons behind the remarkable efficacy

what to do about a rusty air conditioner

What to Do About a Rusty Air Conditioner

Your air conditioner endures significant wear and tear throughout its lifespan. While modern units are designed to be highly durable and capable of withstanding harsh conditions, they still require regular maintenance to ensure optimal performance. Neglecting proper AC tune-ups and exposing your unit to high moisture levels can result in issues such as rust formation. A rusty air conditioner not only looks visually unappealing but also exhibits poor functioning. A rusty air conditioner may struggle to cool or heat your

Farm-to-Fork: Ensuring Food Standards

Food is subject to extensive regulation, with specific guidelines for various stages of its production and distribution. In the European Union, for instance, there are stringent standards outlined in Annex I of EU law No. 852/2004, which focuses on the hygiene of food products. This regulation emphasises the importance of maintaining clean conditions for animals prior to slaughter, aiming to prevent the risk of cross-contamination. When it comes to food preparation, whether at home or in commercial establishments, there are established

Different Types of Lubricants and Their Applications

Different Types of Lubricants and Their Applications

In general, lubricants are primarily used to decrease friction between two surfaces; however, it is essential to note that each lubricant has unique properties.   Although lubrication may seem straightforward, it is still crucial to understand the different types of lubricants and their applications. This ensures that the appropriate lubricant is always used for the intended application, which can reduce machine downtime and failures.   To begin with, lubricants can be categorised into four main types: oils, greases, penetrating lubricants,
