How to disperse and stabilize pigments

This requirement is usually expressed by saying that the medium needs to be a better-than-theta solvent (i.e. a relatively good solvent) for the polymer chain. In systems where the chains are not so well solvated they will prefer to lie next to each other on the surface of the pigment, providing a very much smaller barrier to inter-particulate attraction.

Using Transparent Iron Oxide Pigments in Wood Finish …

 · The chemical composition of yellow iron is a hydrated form of the red iron oxide and this dehydration process occurs at a relatively low temperature. Since the surface area of transparent iron oxide is significantly higher than opaque iron oxide, the thermal stability is reduced slightly further.

Steel

Mill scale, a form of iron oxide (Fe 3 O 4), is used to reduce carbon content. Aluminum ferrosilicon is added if the steel is to be "killed." A killed steel is one that has been deoxidized to prevent gas evolution in the ingot mold, making a more uniform steel.

4 Ways to Make Iron Oxide

 · To make iron oxide, start by getting an iron source with as much exposed surface area as possible, like steel wool. Then, choose an oxidizing agent, such as hydrogen peroxide, bleach, or salt water. Next, submerge the iron source in the oxidizing agent and wait for it to yield rust, which can take anywhere from several hours to a week depending on the strength of your oxidizing agent.

How to Determine Cutting Speeds for Machining Tools

The outside of the end mill/tire will be zipping past the surface below at 1,320 SFM (surface feet per minute). Okay, but how fast is the thing actually rotating, or its rpm (revolutions per minute)? Since machining centers don’t have gas pedals (nor gages that announce the current cutting speed), spindle rpm is the value we have to plug into the CNC program.
