Propylene glycol is an organic raw material, alcohol compound, chemical formula C3H8O2, it is a colorless viscous absorbent liquid, almost no taste, soluble in water and ethanol and other organic solvents. Although propylene glycol is almost non-toxic, when used in excessive amounts of food additives, it can cause serious sleep and kidney disorders. Propylene glycol is also a combustible substance, which will not deteriorate when stored for a long time, but the opening absorbs moisture. Storage and transportation containers should be made of galvanized iron drum, aluminum or stainless steel. According to the general low toxicity chemical provisions storage and transportation.
In terms of storage, try to avoid direct exposure to propylene glycol, use in an air circulation place, after handling or use must be thoroughly cleaned with water.
Propylene glycol in industrial use is unsaturated polyester resin, epoxy resin, polyurethane resin raw materials, can also be used as plasticizers, surfactants, emulsifiers production raw materials, in the food industry can be used as the manufacture of flavor, food coloring solvent, tobacco lubricant] antifungal drinking fruit ripening preservatives, drug excipients, of course, propylene glycol is also an antifreeze, heat carrier and food machinery lubricant use.
Due to the need to strictly control the concentration of propylene glycol solvents in some working environments, considering safety factors and production efficiency factors, the previous manual sampling analysis method is no longer suitable for modern working conditions. Many production lines have begun to gradually replace old equipment and use online refractometers that detect concentration values on optical principles to control the process of propylene glycol working conditions.
CYR-G-PG propylene glycol concentration online detector is an in-situ online detection concentration instrument, the equipment integrates a variety of functions such as detection and data display, composed of optical detection components and electronic components, 2-3 seconds can produce detection results, high detection accuracy, with alarm and cleaner. The installation method is often used for pipeline bypass installation method or small pipe diameter circulation pool installation, and the pipeline installation accessories can also be selected chuck, flange, immersion type and other suitable installation methods, and can also increase the certification qualification explosion-proof box according to the demand, suitable for various working conditions, to solve the process problems of modern industrial upgrading.
