Process Flow

29 people coming to dinner? No problem! I thought it was all under control. The apple and pumpkin pies were cooling nicely. The turkeys were out of the oven. The ovens were pretty much empty (or at least, I didn’t see billows of smoke). I placidly sipped red wine as […]

Active California Advisory System Needed –  1 ppm PEL for NMP

The Cal/OSHA Standards Board recently adopted a Permissible Exposure Limit (PEL) of 1 ppm for N-methylpyrrolidone (NMP). This PEL will be legally-enforceable throughout California. Because there is no Federal OSHA standard, the California PEL is likely to be, at the very least, inspirational throughout the United. States. Look for the […]

Rust

Yellow, Orange, Gold – Rust! Beautiful as autumn colors, desirable as a patina on some sculptures, terrible on manufactured parts. Corrosion compromises product quality, both by direct impact on surface quality and by contributing to contamination. In critical cleaning, cleaning agents and cleaning equipment can be sources of corrosion. Corrosion […]

The Physics of Cleaning, Part 8: Builders

Oil and water do not mix (at least not readily); so how can manufacturers successfully remove oil from product using water? The key is in the formulation, in the secret blend of “herbs and spices;” or, for fully-formulated aqueous cleaning agents, in the blend of chemical additives, most of which […]

Too Much of a Good Thing

“All things are poison, and nothing is without poison; only the dose permits something not to be poisonous.” This 16th Century statement by Paracelsus states that at some level there can be too much, even of a good thing. Here are 8 examples where “more” is not better for critical […]

Compatibility  – You Can’t Rely on Eye Charts

“The surgery was a success but the patient died.”  As a manufacturer, you are the surgeon. Think of the product as your “patient.” The goal of cleaning is to remove soil, or matter out of place.  If as a result of the washing, rinsing, and/or drying step the product is […]

Breaking News: More Restrictions on HCFC 225 for Cleaning

Think you know all about the HCFC 225 phaseout?  Think again. Here’s a heads-up about a distinct change in the EPA position regarding the phaseout of HCFC 225 (hydrochlorofluorocarbon 225, AK 225). This is a biggie: starting January 1, 2015, in a little over two years, virgin HCFC 225 cannot […]

OTC Progress – Productive Manufacturing and Better Air Quality 

We see positive progress with a developing Model Rule for Solvent Degreasing, from the Ozone Transport Commission (OTC). The goal is to carry out EPA mandates to improve air quality by reducing Volatile Organic Compounds (VOCs). The rule is significant because it may impact manufacturing in the Northeast/mid Atlantic area. […]
