Grease manufacture

Grease Manufacture Selected lube oil fractions are blended with various metallic soaps to produce high viscosit lubricating greases. 

Multipurpose dry chemical extinguishers (20-A 80B-C) should be provided in warehouses and shop buildings where wood, paper, plastics, and other flammable solids, as well as flammable liquids, may be stored. In grease manufacturing and compounding or similar operations where little or no wood, paper, and similar combustibles are stored, but where flammable liquids may be prevalent, potassium bicarbonate dry chemical extinguishers should be used. Extinguishers should be located not more than 75 ft (23 m) away from any potential Class A fire hazard and not more than 50 ft (15 m) from Class B fire hazards. 

Use Intermediate, rubber compounding, cosmetic ingredients, buffing compounds, alkyd resins, emulsifiers, grease manufacture, and candles. 

Use Soap stock, leather dressing, candles, greases, manufacture of stearic and oleic acids, animal feeds, abherent in tire molds. 

The largest volume of grease in use is made from petroleum products produced from naphthenic, paraffinic, blended, hydrocracked, hydrogenated, and solvent-refined stocks. In addition to petroleum oils, other lubricating fluids, such as esters, diesters, silicones, polyethers, and synthetic hydrocarbons, are also used. Of the synthetic fluids used in grease manufacture, the most common type is poly(alpha)olefin (PAO). 

Many types of thickeners are used in the manufacture of modem greases. Each type imparts certain properties to the finished product. Table 5.71 describes some of the typical properties and applications of greases manufactured with certain common thickeners.
