Effect of diatomite on soil evaporation characteristics
For the calcined diatomite, when the mixing proportion is about 3–10%, the increase of the mixing ratio has no obvious influence on the results. The volumetric water content range of the mixture of calcined diatomite at turning point I is 0.124–0.164, the value is about 10% larger than that of the mixture of diatomite. ...

Perlite Filter Aid (PFA) for Vacuum & Pressure Filtration
Filter aids should be added at 500 to 1200 g/m² (10 – 25 lbs/100ft²) of filter area. The precoat is formed by recirculating the filter aid slurry through the filter. The coarser particles deposit themselves first on the screen followed by smaller ones. A precoating rate of 40 L/m²/min. (1 GPM/ft²) is normal.

One Simple Trick Makes Hand Warmers Last a Lot Longer
First, some basics. Most disposable hand warmers contain a mix of iron, water, activated carbon, vermiculite, cellulose, and salt. Once exposed to air, the iron oxidizes and releases heat in the process. After all the iron has reacted, the hand warmer is done and ready for the trash. And therein lies the crucial piece of information.
